Affordances of Augmented Reality in Science Learning: Suggestions for Future Research

Augmented reality (AR) is currently considered as having potential for pedagogical applications. However, in science education, research regarding AR-aided learning is in its infancy. To understand how AR could help science learning, this review paper firstly has identified two major approaches of utilizing AR technology in science education, which are named as image-based AR and location-based AR. These approaches may result in different affordances for science learning. It is then found that students’ spatial ability, practical skills, and conceptual understanding are often afforded by image-based AR and location-based AR usually supports inquiry-based scientific activities. After examining what has been done in science learning with AR supports, several suggestions for future research are proposed. For example, more research is required to explore learning experience (e.g., motivation or cognitive load) and learner characteristics (e.g., spatial ability or perceived presence) involved in AR. Mixed methods of investigating learning process (e.g., a content analysis and a sequential analysis) and in-depth examination of user experience beyond usability (e.g., affective variables of esthetic pleasure or emotional fulfillment) should be considered. Combining image-based and location-based AR technology may bring new possibility for supporting science learning. Theories including mental models, spatial cognition, situated cognition, and social constructivist learning are suggested for the profitable uses of future AR research in science education.

关于初中学生学习动机的调查

天津市初中学生的学习动机大都处于中等水平;初中学生的成功动机和自己责任性随年级的增加而降低;他们考试焦虑的促进的紧张和要求水平的发展趋势呈“马鞍型”。而考试焦虑的失败回避动机的发展趋势呈“峰型”;初中女生的综合成功动机、自己责任性和要求水平比男生强,但考试焦虑的促进的紧张水平比男生弱。
