ABSTRACT

This research investigates students’ learning about the electron transport chain (ETC) process in photosynthesis by watching a video followed by playing a serious board game -Electron Chute- that models ETC. The learning objectives targeted enriching a mental model that students could use to explain the causal relationship of the ETC common misconceptions students hold. Eighth graders (N = 120) participated in a one-day activity using a video and game designed by the researchers to model ETC. This model explained how sunlight energy was converted into ATP involving a flow of electrons. A quasi-experimental design involved a pre-test/post-test essay where students from the two treatments - video only and video+game - were asked to interpret a diagram about ETC. Playing Electron Chute after watching the video was effective on addressing misconceptions about sunlight absorption by chlorophylls, oxygen, ATP and NADPH production and the electron flow during ETC. A survey collected data about students’ experiences after the video+game treatment. The majority of students agreed that playing the game increased their ability to explain how plants use light energy. This study demonstrates a principled approach for designing a video and game to support students’ ability to make sense of how complex systems work.

使用视频和严肃游戏学习光合作用中的电子传递链过程

摘要

这项研究通过观看视频,然后玩一个模拟 ETC的严肃棋盘游戏 - Electron Chute ,调查学生对光合作用中电子传输链 (ETC) 过程的了解。学习目标旨在丰富学生可以用来解释学生持有的 ETC 常见误解的因果关系的心智模型。八年级学生 (N = 120) 使用研究人员设计的视频和游戏来模拟 ETC,参加了为期一天的活动。该模型解释了阳光能量如何转化为涉及电子流的 ATP。准实验设计涉及前测/后测论文,要求来自两种治疗方法的学生 - 仅视频和视频+游戏 - 被要求解释关于 ETC 的图表。玩电子滑道观看视频后,有效地解决了关于叶绿素吸收阳光、氧气、ATP 和 NADPH 产生以及 ETC 期间电子流的误解。一项调查收集了有关视频+游戏治疗后学生体验的数据。大多数学生同意玩这个游戏可以提高他们解释植物如何利用光能的能力。这项研究展示了一种设计视频和游戏的原则方法,以支持学生理解复杂系统如何工作的能力。
