The implementation of learning apps in biological education: a quantitative study of the current situation in Austria

Purpose – This research paper aims to provide information about certified learning apps for biological education and gave an ordered list of all learning apps currently used by Austrian biology teachers in the classroom, which should serve as an overview for all biology teachers. In addition, the (currently little known) certification process of learning apps (seal of quality for educational applications) is described. Design/methodology/approach – Online questionnaire for all biology teachers throughout Austria, on the one hand to find out the apps, and on the other hand toresearch how Austrianteachersfind suitable apps. The data were evaluated using descriptive statistics. Findings – A total of84 different learning apps are currently used by biology teachers in Austria. There are two certified lernapps in Austria, both are used. The most common app in biology lessons is “ Anton ” . The teachers find the information about apps throughout their own research or through colleagues. There are regional and school-specific differences in regards of usage and knowledge about seal of quality. It needs its own teacher training (TT) via suitable learning apps, because problems (data protection, advertising) are sometimes not taken into account during use. Research limitations/implications – Limitations of this paper are that some of the teachers indicated the apps from other subjects (mathematics) to use this learning app, although this is not possible for biology lessons.Dataprotectionwasstatedtothebestoftheauthors ’ knowledgebytheauthors,iftheauthorswerenot sure it says “ unsure ” . The participants are mainly women, but this corresponds to the gender ratio, which is typical of the Austrian teaching profession. Practical implications – The overview of the apps, compiled by this Austria-wide research, can be taken over into the biology lessons of all teachers. In addition, on the basis of this study, a TT at the University of Education 2023 in Linz was created. In addition, the (currently little known) certification process of learning apps is described.

Introduction
The COVID-19 pandemic and digitization (BMBWF, 2020a) have drastically changed Austrian teaching in recent years.Distance learning, hybrid teaching, tablet classes, and a new subject "Digital Education" (BMBWF, 2020b) have recently caused many teachers quite a bit of a stir and presented them with many new challenges (H€ ormann et al., 2021; H€ ormann et al., 2022; H€ ormann et al., 2023).Within emergency remote teaching (ERT), educational applications (learning apps) were increasingly used in distance and hybrid teaching (H€ ormann et al., 2021).Nevertheless, neither then nor now was there a suitable overview with accompanying materials of existing learning apps for the subject "Biology", which covers most of the teaching content, is GDPR compliant (data protection)and affordable for everyone.
Today, if a biology teacher wants to use an educational application, you are faced with one big question: "Which learning app can I use in my classroom?".As a result, in the App stores and online, teachers can find numerous apps (Papadakis and Kalogiannakis, 2017), especially for younger students (Bouck et al., 2016), that are associated with the topics "education" or "biology".Teachers do not want to use "any" learning app, because the mobile or web-based application should be suitable for their lessons, but what criteria do educators use to select them?It is criticized by researchers that there are no apparent quality criteria on the basis of these, how and which learning apps are selected (Papadakis and Kalogiannakis, 2017;Harrison and Lee, 2018).Although there are many specific websites, blogs, print media, or podcasts currently available that review learning apps, according to Papadakis, most of them do not utilize an adequate scientific quality assessment (Papadakis and Kalogiannakis, 2017;Papadakis, 2021).
In a desperate need to create a standard for quality and an overview for all certified learning apps, some EU countries (e.g.Finland, Austria) are now beginning to instrumentalize websites and specific quality assessments based on quality criteria in their countries (BMBWF, 2021;Education Alliance Finland, 2021).In Austria, the Ministry of Education, Research and Development (BMBWF) formed in 2021 a model for quality criteria regarding web-based and mobile educational applications through a state-controlled quality assessment procedure (OeAD, 2021;BMBWF, 2021).With the certification of learning apps, the fifth point of the eight-point plan for digital teaching of the Federal Ministry of Education, Science and Research (BMBWF) is realized (BMBWF, 2020a).The evaluation and certification, performed by the Ministry of Education, and the Austrian Agency of Education and Internationalization (OeAD) (OeAD, 2021;BMBWF, 2020aBMBWF, , 2021)), introduce quality assurance.The associated "seal of quality" is intended to offer teachers, students, but also legal guardians, and other interested parties orientation in the selection of learning apps (OeAD, 2021).The eight-point plan for the digitization of Austrian schools involves all central areas of the education system that are necessary for high-quality, future-oriented school operations (BMBWF, 2020a(BMBWF, , 2021)).

Austrian certification process and current status of certified science apps in Austria
Therefore, to answer the question: "How can a learning app get the Austrian seal of quality (German: G€ utesiegel), and how does the certification process work?".The certification procedure is standardized in several steps over a period of several months (OeAD, 2021;BMBWF, 2021).First, app developers submit the app for the certification process, which then are checked for elimination criteria (e.g.available for both iOS/Android, General Data Protection Regulation-compliant (GDPR), no advertising) by the OeAD.After a positive analysis and assessment by three evaluators (in-service teachers), on the basis of an evaluation grid (OeAD, 2021;BMBWF, 2021;Schmidthaler et al., 2022), the app receives the "seal of approval" for two years and is publicly marked as "certified" on the OeAD website (OeAD, 2021).Currently (January 2023), there are 35 certified learning apps for 20 subjects JRIT available in Austria (OeAD, 2021).Therefore, not all school subjects and school levels (only secondary school) are covered.In addition, all certified apps are provided for fifth grade and higher, 24 are free of charge (OeAD, 2021;Schmidthaler et al., 2022) and only two certified apps, "Anton"' and "App ins Holz", are available for the subject "Biology" for all Austrian secondary schools (OeAD, 2021).
Definition: what is an educational application?According to the OeAD, an educational application (learning app) is defined as a mobile or web-based "digital tool that supports independent and interest-driven learning activities as well as learning in the context of school lessons, in which students can develop, practice, deepen, repeat, structure, or apply learning content independently of time and place and pursue their own areas of interest" (OeAD, 2021).In addition, the app is not an organization tool (e.g.calendar).Moreover, the app is no reference work (e.g. term definition), does not serve to design the learning environment and it does not rely exclusively on user-generated content (OeAD, 2021).However, other researchers define an educational application as a mobile learning application (for Smartphone or tablet), designed to assist the user (e.g.children of all ages, students, parents, educators and educational institutions) with remote learning, and gaining knowledge of any kind (Shokurova, 2021;Papadakis et al., 2017;Papadakis and Kalogiannakis, 2017).In the context of this article, educational applications are mobile or webbased learning apps which actively support students or teachers in their learning process, in class or in their leisure time (e.g.lesson preparation, correction, homework and fieldwork).

Benefits of educational applications
There are multifold advantages regarding the utilization and implementation of learning apps into the learning process and education, according to current research (Shokurova, 2021;Camilleri and Camilleri, 2019;Qing, 2017).By definition, a learning app assists its user within their learning process (Shokurova, 2021;Schmidthaler et al., 2022).Additionally, they are user-friendly, and can be employed, regardless of location and time, to provide information very quickly.They are oftentimes more specific or up-to-date than analogue material (e.g.printed literature).In addition, in terms of the weight of the school bag, digital technologies are more back-relieving for the students (Camilleri andCamilleri, 2019, 2020;Qing, 2017;Schmidthaler et al., 2022;Papadakis, 2021).The apps' design and tasks (e.g.providing immediate feedback, error detection, quizzes, exercises and multimedia features) are simplifying the learning procedure and assist the user (e.g.students or teacher) to learn in an intuitive and automatic way (Papadakis et al., 2017).Therefore, according to many studies done by the authors and other researchers, learning apps have the possibility to increase fun, engagement, commitment, self-confidence, collaboration and learning outcomes during a lecture, by possibly working at their own individual level (Alonso-Martinez et al., 2019;Gangaiamaran and Madhumathi, 2017;Camilleri andCamilleri, 2019, 2020;Qing, 2017;Shokurova, 2021;Schmidthaler et al., 2022Schmidthaler et al., , 2023a, b;, b;Papadakis, 2021;Shapley et al., 2011;Saidin et al., 2015;Kruchinin and Bagrova, 2021;Harrison and Lee, 2018).Moreover, besides the many student-centered advantages, there are also recommendations from the BMWBF, to use the latest digital technologies in school (BMBWF, 2018(BMBWF, , 2020a)).

Disadvantages of educational applications
In addition to these many advantages, however, there are also concerns and drawbacks in terms of using learning apps.Some educators and guardians are worried that the students will become dependent on their smartphone applications and therefore neglect real-life social contact.Furthermore, there are concerns that whilst learning with the smartphone (m-learning), notifications from other apps (e.g.social media) could distract children.Therefore, these disturbances and distractions might prevent learning success and could lead to undesired learning outcomes (Schmidthaler et al., 2022(Schmidthaler et al., , 2023a;;Papadakis and Kalogiannakis, 2017;Dong et al., 2020).Furthermore, for effective usage, WIFI or mobile data, as well as technical devices are required, and not every student or teacher can fulfill these technical requirements.In addition, some learning apps are not free of charge, are not data protection compliant, contain advertising, in-app purchases, incorrect or incomplete information, or (age-)inappropriate content (BMBWF, 2021;Schmidthaler et al., 2022Schmidthaler et al., , 2023a;;Papadakis and Kalogiannakis, 2017;Dong et al., 2020).Therefore, there is a high demand regarding assistance and quality assessment for teachers, parents and students, to help them not wasting their time utilizing inferior or inappropriate apps (Papadakis et al., 2016).
Joly et al., tried to find out if Pl@ntnet could be effectively used as a sustainable determination tool.This analysis clearly showed the high attractiveness of the app as well as the potentially huge amounts of botanical observations that could be produced and observed.On the other hand, the limitations of current data flows were also highlighted (especially the bottleneck in validation) (Joly et al., 2016).In another study (2022), Pl@ntnet was tested with 86 secondary school students.Students had to identify six plants with the Internet, with the app, and with the textbook.Results showed that children had the least problems using the app (with the Internet solely the most) but preferred to use a textbook.The authors propose a combination of Pl@ntNet and a pictorial identification key for identification exercises (Lang and Sorgo, 2022).Otter et al. (2021) did a comparison of popular iPad applications: Picture It, Pl@ntnet and PlanSnap.Seventeen toxic plants could be identified with those three apps.Findings indicate that PictureThis had the best performance (59% correctly), followed by Pl@ntnet (47%), and PlantSnap (5.8%).The authors suggest that Pl@ntnet and Picture It could be of assistance in identifying toxic plants (Otter et al., 2021).
The second biological topic area where learning apps are used is in cell biology.Mobile applications and their educational quality were already assessed (de Oliveira and Galembeck, 2015;Stark, 2012).Stark (2012) provides an overview and description of cell biology educational apps for Apple devices regarding this topic (Stark, 2012).In another study by Lustosa de Oliveira and Galembeck (2015), 97 cell biology apps were surveyed in order to identify whether there are new approaches for modeling cells using the latest technologies.Findings indicate that cell apps might perform an essential role in cell modeling, because of their sophisticated design with easy-to-use features.The authors concluded that most of the analyzed learning apps for cell biology have a "great potential to expand the practice and delivery of cell biology teaching and many other areas in biological education" (de Oliveira and Galembeck, 2015).
The third major area where biological learning apps are more likely to be used is the wide field of human anatomy (Çelik et al., 2020), especially apps with augmented reality (AR) JRIT functionality or 3D visualization, such as 3D Anatomy or Insight Heart.Research regarding the perceptions of Austrian teachers and students on mobile AR apps (mAR) has already been done by the authors (Schmidthaler et al., 2023a).Studies show that mAR enables complex and abstract biological content and concepts to be better understood and visualized for students (Yapıcı and Karakoyun, 2021;Fuchsova and Korenova, 2019;Çelik et al., 2020).Henceforth, it is no surprise that educators are more likely to implement such promising mobile AR apps in their biological education classes (Çakır et al., 2021).
There are also many studies on the subject of "sustainability" in connection with learning apps, such as Codecheck App or Labels for your Planet (Vortmann, 2019;Alonso-Martinez et al., 2019).The findings of a study ( 2019) indicate that through the employment of learning apps in the classroom students showed an expansion of their interest in environmental issues.The authors suggested teaching sustainability and environmental topics in a combination with more traditional teaching methods to increase the students' learning effects (Alonso-Martinez et al., 2019).In a secondary school experimental study with students on microplastics in cosmetic products, the authors refer to the possible use of the app in combination with a physical experiment in school (Vortmann, 2019).
Description and research regarding "Anton" and "App ins Holz" In the learning app "App ins Holz" biological topics, such as ecology of the forest, wood, paper and climate protection, are discussed.The app includes flashcards and has a quiz function.Furthermore, the application is ad-free, GDPR compliant, and available for free download in the App Store (Android and iOS), as well as free of charge as a web-based app on all devices (as shown in Table 2).The app was developed as part of a "citizen science project" of the Innovation Foundation Education.Particularly noteworthy is the free manual for the app, which students, teachers and parents can download, and the feature that users have to reach a predefined weekly goal (Pro: Holz, 2022).
"Anton" is the learning app for many subjects besides biology (including Russian, Ukrainian, German, German as a foreign language, Mathematics, Physics, etc.) from preschool to higher secondary school (Anton, 2020).The app currently contains over 100,000 tasks, 200 interactive exercise types, explanations and learning games, and is constantly updated and supplemented.Like "App ins Holz", all learning content is free of charge and without advertising (as shown in Table 2) (Anton, 2020;Apple, 2022)."Anton" is GDPR compliant, and includes rewards (e.g.collecting stars and trophies), quizzes, and games.Moreover, the app can be useful for teachers and school classes, because it allows the user to create an entire school class, assign tasks and track learning progress (Anton, 2020;Apple, 2022).

Learning apps in biology
With the certified learning app "Anton" (Anton, 2020), a qualitative study was carried out on the importance of the mobile app in the subject "German as a second language".The authors conclude that "Anton" is recommended for beginners with only little language skills, but to be able to speak and write a new language really fluently, the app is not sufficient (Erim and Sarı Bıyık, 2021).However, considering an article in "Medienimpulse" (2019), the app for language learning is mentioned very positively and is recommended for teaching (Rotschopf, 2019).Furthermore, "Anton" is also recommended to educators because the app can be used as an aid for targeted, and to use interaction-based teaching as mobile applications can be an enrichment for all learners (Erim and Sarı Bıyık, 2021).Clemens and Thibaut (2020) describe that during the COVID-19 pandemic, the app was used in elementary school.It is criticized that the sole use of "Anton" in distance teaching has no advantages for the relationship level between students, parents and teachers (Clemens and Thibaut, 2020).In another study, in which "Anton" was used in mathematics lessons, the participating students showed increased and sustained motivation in learning, as well as an increased willingness to make a higher effort compared to analog learning methods.As a result, the authors conclude that digital learning with the app "Anton" for targeted tasks is a decisive factor influencing the learning success of the students (M€ uller and Sagmeister, 2022).Both apps ("App ins Holz" and "Anton"), are advertised online on the official Austrian website for teachers (Lehrerweb, 2022), but scientific studies related to the subject of biology are completely missing.There are no studies on "App ins Holz" yet, as the app is still very new and has only recently appeared on the market (Pro:Holz, 2022).

Research question and aim
The main aim of this research is to provide an overview of the learning apps which are currently used by biology teachers in Austria.Concerning this research, the overview of all learning apps in biology lessons as well as their descriptions will be published as Open Educational Resource (OER) on a website accessible to everyone (COOL Lab, 2020), and serves a basis for upcoming teacher training (TT) in 2023 at the University of Education in Linz ("P€ adagogische Hochschule").
In addition, it was also investigated where Austrian biology teachers receive information about suitable learning apps.Secondly, this study wants to find out whether Austrian biology teachers use certified educational applications and visit the website for certified learning apps (BMBWF, 2021) promoted by the Ministry and the OeAD in their search for apps, or not.

Data collection and processing
The data of the Austrian biology teachers were collected via an online survey using the tool LimeSurvey and took place from September 2022 until December 2023.The questionnaire (target group: all Austrian biology educators) was sent out to more than 400 schools from every federal state.It consisted of demographic questions, one openended, and five closed-ended questions (Yes/No (y/n), multiple choice (MC), and single choice (SC): (4) Do you know the "Seal of Quality" for learning apps in Austria?(y/n) (5) How do you find a suitable learning app for your lessons?(MC) (6) Which one of the mentioned options is your preferred method for finding a new learning app? (SC) All the quantitative data were processed using descriptive statistics (via spreadsheet), as recommended in similar studies (And i c et al., 2018(And i c et al., , 2019;;Mikropoulos et al., 2003) and previously done by the authors (Schmidthaler et al., 2022(Schmidthaler et al., , 2023a)).Additional qualitative data (name of apps), were collected in an Excel Sheet, manually checked, according to exclusion criteria, and entered into a list with several items, based on the evaluation grid of the certification process by the OeAD and BMBWF (e.g.data protection, advertising) (OeAD, 2021; BMBWF, 2021).The following elimination criteria were determined by the authors: ( 1) "ambiguity" (due to serious spelling mistakes; several similar-sounding apps); "wrong subject assignment", "no learning app by definition".

Sampling
In this mixed-method study 117 (87.18% female, 12.82% male) Austrian in-service secondary school biology educators participated in.The distribution of school types, and participating federal states are shown in Table 1.The average age of participants was 42.85 years (y) (Standard deviation 5 11.52 y; Minimum 5 23 y; Maximum 5 64 y), and had an average service experience of 16.82 y (Standard deviation 5 12.07 y; Minimum 5 0 y; Maximum 5 40 y).
In terms of school location and type of school, only secondary school teachers from all federal states (except Carinthia) took part, but the majority of the teachers surveyed work in Lower Austria (52.14%), followed by Upper Austria (23.08%) and Vienna (10.26%).In addition, predominantly middle school teachers (52.99%), followed by general secondary school teachers (43.78%) and special education teachers (21.22%), answered the online questionnaire, as shown in Table 2.

Results
In the following the quantitative results are provided and presented in two topics: (1) An Overview of the Implementation Regarding Educational Applications in Austrian Biology Lessons (2) Access Possibilities and Usage of the Website "Quality Seal for Learning Apps"

Learning apps in biology
An overview of the implementation regarding educational applications in Austrian biology lessons When asked if they know what a learning app is, 99.15% of the biology teachers surveyed answered this statement in the affirmative.Also, 81.20% of teachers (n2 5 95) are employing learning apps in their biological education, as shown in Figure 1.
The findings of the quantitative online survey showed that 95 participants are using at least one learning app in their biological education, eighteen apps maximum (n 5 117; arithmetic mean: 2.5; median: 2), as shown in Figure 2. Furthermore, younger teachers, especially 30-40-year-olds, tend to use learning apps in class.In the first years of service and with increasing age, app usage decreases, as shown in Figure 3.
Furthermore, the educators, who know what a learning app is (99.15%) and are app-users (n 5 95) in their class, are implementing 84 different apps in their biology lessons.Tables 3  and 4 show excerpts of all apps, divided into two groups: apps, which contain biological and science-based content (e.g."Pl@ntnet", "Seek", "Flora Incognita"; f1 5 54) and apps, which do not contain such topics (e.g."Mentimeter", "Quizlet", "Kahoot"; f2 5 30).Further, all apps are distinguished into "non-certified" and "certified" learning apps ("seal of quality").In addition, they are classified according to whether they are a "web-based" and/or a "mobile" application ("usability").Moreover, data regarding frequencies of usage and the web-pages of the applications are provided.Furthermore, possible costs, advertisements, data protection In summary, 95 Austrian biology secondary school teachers use 82 uncertified and two certified ("Anton" and "App ins Holz") learning apps in their lessons.Fifty-four contain full or in parts biological content, and 30 do not have biological or science content whatsoever.The majority of the apps are available as freeware (f 5 77), however 30 of the stated learning apps in use provide in-app purchases.Furthermore, 22 contain advertisements, and 30 are not GDPR compliant, or there was no clear evidence regarding data protection found.All evaluated mobile learning apps are available for IOS (f 5 45).Only 86.67% of the mobile apps (f 5 39) are accessible for Android, and web-based app-users employ 18 (37.5%)applications in their education.
Apps were not included in the list, if, firstly, they were not a learning app by definition of the authors (e.g."Moodle", "Schoolfox", "Eduthek"), they were misspelled to the point of being unrecognizable, or there were similar-sounding apps in app stores available (ambiguity) (e.g."Plus").Lastly, if the learning app can be clearly assigned to another subject (e.g."Bettermarks", "Geogebra", "Matheluisa", and "Mathearena" to mathematics), it was not considered either.
Access possibilities and usage of the website "Quality Seal for Learning Apps" The participating biology teachers stated that they mainly find suitable or new learning apps for their biology lessons through their colleagues (63.25%) or through their own research on the internet (50.43%).These two methods are the first choice of their preferred search method and access possibility (as shown in Figure 4 and Table 5).Respondent two (female, AHS, 29): "I prefer to hear experience reports (about the apps) from my friends.In practice, my own research on the Internet (for suitable apps) is the first choice".Another teacher wrote (Respondent three: female, middle school and special education teacher, 55) that her preferred method is to "share experiences with (her) colleagues".In addition, the participants also get to know new learning apps through the assistance of their friends (17.09%), social media  Learning apps in biology (13.68%), and school meetings (14.53%).Only a few teachers visit the OeAD website for certified learning apps (9.40%), or get their information directly from the ministry (1.71%), as 70.09% of participants did not even know the OeAD website (Figure 1).Concerning the federal state comparison with regards to employment location of all participants, in Vienna (33.33%) most teachers know about the seal of approval for learning apps, followed by Lower Austria (31.15%) and Upper Austria (29.63%).In other federal states, no comparison was made due to insufficient number of participants.Four participants (4.26%) visit the website "Quality Seal for Learning Apps" as a first preference in their search for new suitable educational applications (Table 5).One respondent (33, male, general lower and higher secondary school teacher) stated that he "only uses (his) self-designed apps".
With regard to the comparison of school types in terms of employment, it can also be seen that in Austrian middle schools 90.32% of the biology teachers use learning apps in their lessons, followed by general secondary school (AHS: lower 80.77%; higher 76%), as shown in Figure 5.There is a trend that schools with a certain focus (e.g.vocational training, inclusion and special needs) tend to use fewer learning apps.It can also be observed that in schools with younger students (aged: 10-14 y) without vocational training and special care (lower AHS, MS), slightly more biology teachers use learning apps than with older students in higher school classes (BMHS, higher AHS).

Discussion
This study investigated which learning apps are used by Austrian secondary school teachers in biology lessons.Further, it was explored, where do these educators access or find educational applications for their students.The stated learning apps were checked according to predefined exclusive criteria (BMBWF, 2021) and afterward presented in an overview.

JRIT
It is worth mentioning in terms of limitations that predominantly women are participants in this study.However, since no gender-specific links and conclusions have been drawn, and the Austrian distribution in the teaching profession corresponds to that of this study, this point can be neglected (BMBWF, 2020c).Furthermore, it must also be mentioned that there was disagreement regarding three apps and their assignment.Most of the apps that were excluded from the assignment from the final overview table were those that were linked to another subject.It was discussed within the team whether "Schoolfox", "Moodle" and "Geogebra" are suitable learning apps in biological education, since "Geogebra" has the possibility to create a "Geogebra book", with possible use in the subject of biology."Schoolfox" and "Moodle" finally were excluded because these apps are used by educators in class, for their preparation, communication with students and parents, correction work, or follow-up.Finally, it should be declared that the question regarding the first reference in terms of app search has originally been designed as a SC.The question was mistakenly implemented as an open-ended question in Limesurvey.Therefore, in addition to their first choice, few teachers wrote statements, excerpts of which can be found in the results as direct quotations.
In regard to the final findings, it was pleasing that a certified learning app "Anton" (Anton, 2020;OeAD, 2021), is the most frequently used learning app in Austria according to the participants.Moreover, this circumstance was surprising, as only a few teachers know about the certification process, and therefore about the advantages of the seal of quality.The three most common learning apps ("Anton", "LearningApps.org","Kahoot") consist of multimedia and quiz features where students can win prizes or compete against other classmates.These additional features have been discovered in other "Kahoot" studies to increase collaboration, engagement, motivation and participation in the classroom (Virga et al., 2022;Bawa, 2019;Zhang and Yu, 2021).
Further, the differences between federal states in terms of the level of knowledge about the seal of quality were striking.Reasons could be the proximity of the Ministry of Education, different assessment strategies throughout the states, or the higher population density in the capital city.It was to be expected that app use decreases with increasing age, but surprisingly many more experienced teachers still use a lot of different learning apps in biology lessons, although the knowledge about the certification is so low, and suitable overviews, as well as additional teaching material are lacking.Therefore, this study can dispel the myth that older teachers refuse to use the latest technologies and apps in relation to biology lessons in secondary education.

Learning apps in biology
In terms of usage, it was noticeable that more MS teachers are app-users than in all other school types.Reasons for this could be on the one hand the school specific focus (vocational training, inclusion), and on the other hand the age of the target group.Nevertheless, there are also differences in terms of implementation in comparison between lower AHS level and MS.In consideration of that, it can be assumed that learning apps are still not rewarded as a sustainable teaching method in the minds of some AHS teachers.Further studies must take place with regard to this presumption.
Due to the often very scarce school budget, it was not surprising that the majority of the apps used were free, or available as a free version, but it is frightening how many teachers use apps, although they sometimes contain inappropriate or annoying advertising and in-app purchases (Schmidthaler et al., 2022(Schmidthaler et al., , 2023a)).This can lead to unwanted subscriptions and further problems with students or parents.Moreover, it seems that in addition to advertising, no attention is paid to data protection.Hence, it can be assumed that some teachers themselves have little or no idea about Data Protection Regulation or other dangers in dealing with learning apps (e.g.inappropriate content (Schmidthaler et al., 2022), or apps in general with chat or comment sections (e.g."Youtube", "TikTok") (e.g.cybercrimes (Almadhoor et al., 2021)).This circumstance could be due to their possible ignorance, or lack of knowledge or training, partly probably due to time constraints, or the lack of supply.Therefore, there is a great need to stress suitable TT, to firstly provide suitable apps, and secondly, to emphasize the importance of follow-up sessions in school, as part of digital education".Concerning obtaining information about apps for their profession, word of mouth among colleagues is still the number one source of information.This result is not surprising either, and highlights again the importance of TT tailored to biology teachers.

Conclusion and outlook
After the evaluation of the implementation of educational applications in Austrian biology classes it can be concluded that the majority of all Austrian biology teachers in secondary education use 82 different learning apps.The certified learning app "Anton" is the most common besides "Kahoot" and "Learningapp.org",due to their motivating, entertaining and engaging quizzes, and multimedia applications.Furthermore, it can be assumed that many Austrian biology teachers have a lack of knowledge regarding safety issues in terms of learning apps, and there is a great need to fix that issue with special TT.
In order to test the assumption that middle school teachers are more positive about learning apps and that AHS teachers use them less frequently because they do not consider it a suitable teaching method, a qualitative study will be conducted in 2023/24 where biology teachers from both types of schools (MS and AHS) will be interviewed.In addition, another Austria-wide quantitative study regarding motives, opinions and frequency of use will take place in 2023; and an additional qualitative study to highlight strengths and weaknesses for biology teachers and their students in the classroom, according to secondary school teachers, will take place at the beginning of 2023.In addition, on the basis of this study, and additional quantitative results of a second study, a TT ("apps-periments") specially tailored to the wishes and needs of Austrian biology teachers will be developed and will take place at the University of Teacher Education Linz ("P€ adagogische Hochschule") in 2023.
