Ninth-grade students’ perceptions on the design-thinking mindset in the context of reverse engineering

Abstract

Recently, design thinking has become recognized as a necessity for every student, especially when they engage in design-based learning, as a pedagogical approach to science, technology, engineering, and mathematics education. However, design-based learning is mostly based on forward engineering, in which students' design thinking can be nurtured by designing unknown solutions. Little is known about whether design thinking can be facilitated in the context of reverse engineering, when students learn from already designed products. This study therefore seeks to explore the perceptions of 38 ninth-grade students on the characteristics of design thinking before and after a four-week reverse engineering project, using Likert scales to measure six aspects of design thinking, namely (a) being comfortable with uncertainty and risks, (b) human-centeredness, (c) mindfulness to the process and impacts on others, (d) collaboratively working with diversity, (e) orientation to learning by making and testing, and (f) being confident and optimistic to use creativity. The data were analyzed using descriptive and inferential statistics, including means, standard deviations, paired-samples t-tests, and Wilcoxon signed-rank tests. The results indicate that two aspects, human-centeredness and being confident and optimistic to use creativity, were significant (p = 0.008 and p = 0.043, respectively), with size effects of 0.43 and 0.34, respectively. Based on this potential, reverse engineering can be a design-based learning approach to facilitate students' design thinking. It is recommended that instructional activities involving reverse engineering maintain some degree of ambiguity and risk to prevent design fixation among students.

Analysis of Students' Design Thinking in Creating 3D Creative Works Utilizing Mobile Technology within the Framework of Local Wisdom

“…These findings align with previous research indicating that technology-based courses that emphasize hands-on learning yield higher design thinking scores compared to traditional teaching methods (Lin et al, 2020). Furthermore, prior studies have also demonstrated that students' design thinking performance improves when involved in design-based learning (Ladachart et al, 2022).…”

“…Quantitative data were collected using a self-perception questionnaire called the Design Thinking Scale, developed by Ladachart et al (2022). This instrument assessed six indicators of students' design thinking competencies, including comfort with uncertainty and risks, human-centeredness, mindfulness of process and impacts, collaborative work with diversity, orientation to learning by making and testing, and confidence in using creativity.…”

Cultivating a Design Thinking Mindset in Educationally Disadvantaged Students Using a Design-based Activity

“…In Thailand, where this study was conducted, DT has gained increasing attention because of the STEM education policy. As Thai scholars, we also used Dosi et al's (2018) comprehensive list of aspects of DT to measure teachers' and students' perception of their DT (Ladachart, Ladachart, Phothong, & Suaklay, 2021;Ladachart, Cholsin, Kwanpet, Teerapanpong, Dessi, Phuangsuwan, & Phothong, 2021). While DT can be measured in several ways, measuring individuals' perceptions of their own DT using Likert-type surveys can 'provide insights about the extent they are able to think like designers' (Koh et al, 2015, p. 115).…”

Designing a Flipped Learning-Based Education Model (Case Study of Education in the Districts of Tehran Province)

“…Therefore, a flipped classroom in elementary school would look different from one in high school (Gholami et al, 2023). From about 6 to 11 years old, roughly the years of primary or elementary school, children become proficient in basic skills such as reading, writing, and arithmetic, show interest in discovering and understanding their surroundings, and their personal control increases (Ladachart et al, 2022). Children are the most valuable human assets of any society and play a significant role in shaping the future of any country, but they can only fulfill this role properly if they are empowered with the necessary capabilities.…”
