摘 要

本研究利用眼动追踪技术考察了中学生在解决科学问题时的信息加工模式与特征,为提高中学生解决科学问题能力、培养学生科学素养提出合理性建议。我们采集了126名初三学生在解决6个PISA经典科学问题时的眼动数据,在通用眼动数据分析的基础上发展了兴趣区注视序列折线图方法,结果表明:(1)相比于错误解决科学问题的学生,正确解决科学问题的学生其总注视持续时间、注视次数更多,更集中于问题的关键区域,即推理、选项区域。(2)相比于错误解决科学问题的学生,正确解决科学问题的学生能够在文字条件与图片选项的不同兴趣区之间中进行准确匹配。(3)在正确解决科学问题的学生中,存在着顺序和交互两种不同的眼动模式。(4)在正确解决科学问题的学生中,女生在总注视持续时间、注视次数两个指标上显著高于男生,且更集中于背景文字区域。上述眼动结果表明,相比于错误解决科学问题的学生,正确解决科学问题的学生具有较高的图文转换能力,进行了更深入的认知加工和更复杂的注意分配,从而能够更好地协调和整合信息。在正确解决科学问题的学生中,相较于交互眼动模式,采用顺序眼动模式的学生更全面地掌握了概念和模型,具有较大的工作记忆,能够高效快速地解决科学问题。在正确解决科学问题时,男、女生采用了两种不同的认知策略:男生解题时对于题目的理解更加有把握且认知加工更快,而女生更注重解题的细节把握,采取缓慢谨慎的解题策略。

Abstract

This study used eye tracking technology to explore the information processing patterns and characteristics of middle school students in solving PISA scientific problems which can be not only beneficial to improve the scientific problem solving ability of middle school students in practical science teaching, but also provide reasonable and valuable suggestions for cultivating students' scientific literacy. We collected eye movement data of 126 junior high school students in solving six PISA scientific problems. Based on the analysis of general eye movement data, we produced a graph that included both time-on-item and fixation location that we have termed a zone graph. Our eye-tracking research found that: (1) Total fixation duration and total number of fixation of the correct problem solvers are significantly higher than those incorrect problem solvers. This means that the correct problem solvers are more focused on the key areas of the problem, namely, reasoning areas and option areas. (2) The correct problem solvers can match description information and diagram information more accurately than incorrect problem solvers among different interest areas. (3) There are two different eye movement modes among the correct problem solvers, namely, sequential mode and interactive mode. (4) Among the correct problem solvers, total fixation duration and total number of fixation of the girls are significantly more than the boys, which means that girls are more concentrated in the background and descriptive information.

The above eye movement results reflect that: firstly, compared with the students who cannot success in solving scientific problem, the correct problem solvers have higher converting and integrating ability between description and diagram information. Meanwhile, they carry out more in-depth cognitive processing and more complicated attention distribution. Secondly, students adopting the sequential eye movement mode have a more comprehensive understanding of concepts and models and have greater working memory so that they can solve scientific problems more quickly and efficiently than those in the interactive eye movement mode. Lastly, when solving scientific problems correctly, boys and girls adopt two different cognitive strategies: boys usually solve problems more confidently and their cognitive processing is faster. By contract, girls often pay more attention to the details of the problem and take slow and cautious problem-solving strategies in general.
