Abstract

Purpose

This paper proposes the combination of rapid prototyping and physical modelling as a set-based concept evaluation method in the early stage of new product development.

Design/methodology/approach

The concept evaluation method is applied in a case study of a new metal additive manufacturing process for aluminium, where a set of four extruder concepts has been modelled and evaluated. Rapid prototyping was used to produce plastic models of the different designs, and plasticine feedstock material was used to physically model the metal flow during operation. Finally, the selected concept has been verified in full-scale for processing of aluminium feedstock material.

Findings

The proposed method led to several valuable insights on critical factors that were unknown at the outset of the development project. Overall, these insights enabled concept exploration and concept selection that led to a substantially better solution than the original design.

Research limitations/implications

This method can be applied for other projects where numerical approaches are not applicable or capable, and where the costs or time required for producing full-scale prototypes are high.

Practical implications

Employing this method can enable a more thorough exploration of the design space, allowing new solutions to be discovered.

Originality/value

The proposed method allows a design team to test and evaluate multiple concepts at lower cost and time than what is usually required to produce full-scale prototypes. It is, therefore, concluded to be a valuable design strategy for the early development stages of complex products or technologies.

Abstract

Purpose

This research study explores the perceptions of the importance and meaning of innovation in education by qualified teachers. The authors deliberately selected geography teachers for the research because the extraordinary dynamics of changes and innovations the teacher has to deal with are significantly reflected, particularly in geography teaching.

Design/methodology/approach

The main aim of the research was to determine geography teachers' views on the importance, role and meaning of innovation in teaching. The research group consisted of 12 qualified teachers, and a semistructured interview was chosen as the research method. The research was conducted over six months, from October 2020 to March 2021.

Findings

This research confirmed the interest in introducing innovations into teaching by the teachers interviewed. Teachers mainly think of innovation as new ways of teaching that aim to revive and make teaching more attractive, to increase the motivation of all actors in the learning process. While teachers with more ample teaching experience connect innovations mainly with presentations, education games, and excursions, teachers-beginners and teachers with shorter teaching experience understand innovations mainly as the application of new trends in education, such as research projects and working with GIS and digital technologies. The research confirmed that lectures supported by presentations are the most frequently used teaching method for explaining the geography curriculum in primary and secondary schools. Presentations in which teachers focus on linking relationships and explaining connections more deeply replace existing textbooks and teaching texts for most teachers interviewed.

Research limitations/implications

The number and qualifications of the teachers involved in the research.

Practical implications

Teachers see the quality of the school environment and the education system as the significant barriers to providing better geography education. They often come to innovations through their own study and activities and feel a significant lack of available materials for the practical application of innovations in teaching. They also perceive the support for creation by state authorities and educational institutions as insufficient. Most teachers interviewed would welcome regular training courses and vocational education on the appropriate introduction and use of innovations in the classrooms in the form of practical examples and developed methodologies.

Originality/value

The selection of teachers for the research was deliberate and included active teachers of both genders working in primary and secondary schools. The selected teachers had varying teaching experiences and studied different combinations of teaching subjects with geography.

Abstract

Purpose

The paper aims to examine the concept of architectural design communication (ADC) for updating design studio dynamics in architectural education during the Covid-19 pandemic. Within this perspective, the changing and transforming contents of architectural education, the thinking, representation and production mediums are examined through the determined components of ADC. There are five components in the study, which are (1) Effective Language Use, (2) Effective use of Handcrafts, (3) Effective Technical Drawing Knowledge, (4) Effective Architectural Software Knowledge and (5) Outputs.

Design/methodology/approach

The research method is based on qualitative and quantitative methods; a survey study is applied and the comparative results are evaluated with the path analysis method. The students in the Department of Architecture of two universities have been selected as the target audience. Case study 1 survey is applied to Altinbas University (AU) and Case study 2 survey is applied to Universitat Politecnica de Valencia (UPV) students during the COVID-19 pandemic; ‘19-‘20 spring term, online education.

Findings

As a result, two-path analysis diagrams are produced for two universities, and a comparative analysis is presented to reveal the relationships of the selected ADC components.

Originality/value

This paper fulfills an identified need to study how ADC can be developed in online education platforms.
