On the basis of teachers’ misconceptions to typhoons, the study aims to develop a teaching aid of typhoon augmented reality in science field of elementary school by using design-based research. To understand the acceptance and suggestions from the experts and learners toward the interface design, content difficulty and conceptual model, the teaching aid is going along through analysis, design, development and formative evaluation.
According to the literature, one of the sources of students’ misconceptions is from teachers’ instruction. However, there is a high percentage of science teachers who are non-science background. Those teachers are easy to convey their own misconceptions to students if they are just scripted or think intuitively. Moreover, these misconceptions could continually affect students’ learning. They may even neglect the preparation against typhoons. Thus, in light of the teachers’ three misconceptions: direction of rotation, wind speed distinction and the rain differences, the study develops a teaching aid by adopting design-based research. It is expected that science teachers will avoid or correct their misconceptions. To sum up, augmented reality is a new application of integrating technology into teaching, which involves virtual objects in real environment, allowing the expansion of environmental information and interactions.
The teaching aid is revised by four experts under formative evaluation after the first prototype is finished. Next, the teaching aid is amended according to the experts’ suggestions. Then, five non-science background teachers are asked to use the second revised prototype. After that, the teaching aid is modified in terms of learners’ formative evaluation. Finally, the development of teaching aid is done.
To ground on the result of formative evaluation, the experts consider the teaching aid can highlight typhoon’s structures and achieve the design goals by adding text tips and strengthening contrast effects. What is more, most learners agree that this teaching aid can correspond to learning objectives and is easy to use. The overall assessment is beneficial. In the end, form the perspectives of augmented reality, misconception and design-based research, some suggestions for future research are proposed.
