The purpose of this study is to investigate WhatsApp application for teaching and learning in higher education institutions (HEIs). The consideration for the use of the WhatsApp is based on its usefulness, ease of use, low cost of data and maintenance practices for the functionality of the mobile device used for the WhatsApp.

This paper applied systematic literature review in conceptualizing how WhatsApp application could be used for enhanced teaching and learning in HEIs. Most of the articles used in carrying out this study were harvested from Google Scholar. This study was carried out within three weeks internal

This study established that WhatsApp has also served as a learning and teaching tool which has made majorities of university students, irrespective of their geographical locations, become tech-savvy, self-expressive and open to new ways of doing things, including the use of social network applications. The exposition of the authors based on the findings from this study indicates that through the use of WhatsApp, activity theory of mobile learning postulated by Vygotsky and theory of connectives by George Siemens gave them the understanding surrounding how humans interact with technology through continuous use of tools.

This research carried out has a lot of implications to global HEI due to innovation and practices of teaching learning and research.

WhatsApp application has become the avenue through which people learn and retain and share information and knowledge among themselves for a better quality live scenarios. It has brought a shift from traditional to virtual platform of user experience (UX) in the use of digital technologies.

WhatsApp application for teaching and learning in HEIs established that the impact of WhatsApp on teaching, learning and retention of collocation of knowledge among school students or learners cannot be undermined. The result revealed from this study indicates that there is a shift from traditional to virtual platform which has brought diverse opportunities of transformation the educational systems, enhance productivity and quality service delivery and challenges, where lecturers would have to learn and unlearn through UX of the use of digital technologies.

The lecture method has been compared with teaching methods such as flip learning, cooperative learning and simulations to establish which holds the key to students' understanding of concepts. What is bereft in the education literature is its comparative efficiency with the culturo-techno contextual approach (CTCA) in the teaching of computer science education.

This study adopted the quasi-experimental design to determine the efficacy of the CTCA in breaking difficulties related to the study of spreadsheets as a difficult concept in the Nigerian computer science education curriculum. Junior high school students studying computer science education participated in the study. The control group had 30 students, with 35 students in the experimental group. The experimental group was taught using CTCA, while the control group used the lecture method. The spread sheet achievement test, which had 40 items on spreadsheet, was used to collect data.

The results showed that the experimental group significantly outperformed the control group [F (1,60) = 41.89; p < 0.05]. The findings showed the potential of CTCA in improving students' performance in spreadsheets in the computer science education curriculum.

The originality of this study is hinged on its ground-breaking test of the CTCA to the study of the spreadsheet. The findings of this study indicate its efficacy in improving students' understanding of spreadsheet and computer science education.

This study examines the relationship between higher education improvement and tacit knowledge importance. In this context, the scarcity of empirical and theoretical studies on acquiring tacit knowledge to enhance academic performance in higher education suggests that this research area holds significant importance for experts and policymakers. Consequently, this study aims to explore the factors that influence academic research performance at Chinese universities by acquiring tacit knowledge.

To achieve the study aims, the current approach utilizes the research technique based on the socialization, externalization, internalization and combination (SECI) model and knowledge management (KM) theory. To analyze the study objective, the authors collected data from post-graduate students at Chinese universities and analyzed it using structural equation modeling (SEM) to test the model and hypotheses.

The results indicated that social interaction, internalization and self-motivation have a positive impact on academic research performance through the acquisition of tacit knowledge. Furthermore, the findings suggest that academic researchers can acquire more knowledge through social interaction than self-motivation, thereby advancing research progress.

This study addresses the critical issues surrounding the acquisition of tacit knowledge and presents a comprehensive framework and achievements that can contribute to achieving exceptional academic performance.
