Abstract

Background: In countries that endorse science, technology, engineering, and mathematics (STEM) education as an educational movement, design-based learning is deemed a pedagogical approach. Purpose: Because the integration of the engineering design process and scientific investigation has been an issue in science education, this study examined the effect of initial design experience on students’ understanding of pulleys. Methodology/Approach: We used quasi-experimental research, comparing two experimental groups with one control group in terms of their understanding of pulleys, measured by 10 multiple-choice conceptual questions. We used a one-way ANOVA and Tukey's HSD tests to compare the groups prior to and after design-based learning. Paired-sample t-tests were used to compare the pre- and postscores of each group. Findings/Conclusions: The results indicate that, while the experimental groups did not have a better understanding of pulleys than the control group did in the pretest, they outperformed the control group in the posttest. Moreover, although the control group did not demonstrate a significant improvement, the experimental groups did so with large effect size. Implications: Based on the premises of experiential education, it is suggested that, for design-based activities to be effective, students should design using their prior knowledge before engaging in scientific investigation.
初步设计体验对学生科学理解发展的影响
背景:在认可科学、技术、工程和数学(STEM)教育作为一种教育运动的国家,基于设计的学习被认为是一种教学方法。目的:由于工程设计过程与科学研究的整合一直是科学教育中的一个问题,本研究考察了初始设计经验对学生对滑轮的理解的影响。方法/方法:我们采用准实验研究,比较两个实验组和一个对照组对滑轮的理解,通过10个选择概念题来衡量。我们使用单因素方差分析和Tukey的HSD检验来比较基于设计的学习前后的组。配对样本t检验用于比较各组的前后得分。结果/结论:实验结果表明,实验组在前测中对滑轮的理解并不比对照组更好,但在后测中却优于对照组。此外,虽然对照组没有表现出明显的改善,但实验组有较大的效应量。启示:基于体验式教育的前提,建议学生在从事科学调查之前,应先运用已有的知识进行设计,以使设计型活动有效。

期刊介绍: The Journal of Experiential Education (JEE) is an international, peer-reviewed journal publishing refereed articles on experiential education in diverse contexts. The JEE provides a forum for the empirical and theoretical study of issues concerning experiential learning, program management and policies, educational, developmental, and health outcomes, teaching and facilitation, and research methodology. The JEE is a publication of the Association for Experiential Education. The Journal welcomes submissions from established and emerging scholars writing about experiential education in the context of outdoor adventure programming, service learning, environmental education, classroom instruction, mental and behavioral health, organizational settings, the creative arts, international travel, community programs, or others.
