【摘要】：在当前教育信息化趋势下,PPT课件由其简单方便的特点逐渐成为教师多媒体课堂教学的首选。然而伴随着其在教学中的普遍应用,逐步积累了一些问题,不合理的图片设计便是其中重要的一个。如果教师在课堂教学中,引用了一些对学生学习没有帮助的,甚至可能产生反面效果的课件,最终只会降低学生的学习效率。因此,在PPT课件中合理的设计图文资源便成为衡量现代教师信息技术素养高低的标准之一。随着眼动技术在教育技术领域的运用,研究者可以直接观察到学习者认知加工的过程,了解学习者学习过程中的注意规律,进一步规范多媒体教学方式,会从很大程度上提高学生学习效率。目前,已有大部分学者对PPT课件和图片进行研究,但是利用眼动实验法对这两者进行更加客观的研究与记录,还是少有涉及。本研究以已有的PPT课件研究和眼动方法研究为基础,通过图片呈现方式和图片呈现位置两个实验,对48名初中生的课件学习情况进行研究,分析测试成绩及热点图、注视时间、注视次数、首次进入时间、首个注视点注视时间、访问时间等相关眼动指标,探讨PPT课件中图片设计对学习者的影响,得到以下结果。(1)在不同的图片呈现方式下,测试成绩、注视热点图、注视时间、注视次数、首次进入时间、首个注视点的注视时间六项指标间均存在差异。图文内容相关性高的前提下,图片以动态示意图方式呈现时对初中生有较大影响,且学习效果最好。(2)当图片以不同的位置呈现时,测试成绩、注视热点图、注视时间、注视次数、访问时间指标之间均存在差异。在图文内容相关性高的前提下,右图位置(即图片呈现在文字右侧)对初中生学习的影响较大,且学习效果最好。最后,本研究对两个实验中的各项眼动指标数据进行详细的分析,综合探讨在PPT课件教学中图片设计的规律。研究结论可以给教师PPT课件设计带来指导作用,从而促进更有效的多媒体教学。
[Abstract]:PPT courseware has gradually become the first choice of multimedia classroom teaching for teachers from its simple and convenient characteristics under the current trend of educational informatization. However, with its widespread application in teaching, some problems have been accumulated gradually. Unreasonable picture design is one of the most important ones. If the teacher quotes some courseware that is not helpful to the students' learning and may even have negative effects in the classroom teaching, it will only reduce the students' learning efficiency in the end. The reasonable design of graphic and text resources in PPT courseware has become one of the standards to measure the information technology literacy of modern teachers. With the application of eye movement technology in the field of educational technology, researchers can directly observe the process of learners' cognitive processing. Understanding the rules of attention in learners' learning process and further standardizing multimedia teaching methods will greatly improve the learning efficiency of students. At present, most scholars have studied PPT courseware and pictures. However, more objective research and record of these two methods by eye movement experiment method are seldom involved. This study is based on the existing PPT courseware research and eye movement method research, through two experiments: picture presentation method and picture presentation position experiment. This paper studied the courseware learning of 48 junior middle school students, analyzed the relevant eye movement indexes, such as test results and hot spots, fixation time, fixation times, first entry time, fixation time at the first fixation point, interview time, and so on. This paper discusses the influence of picture design on learners in PPT courseware, and obtains the following results: under different presentation modes of pictures, the test results, the fixation hotspots, the fixation time, the fixation times, the first entry time, On the premise of high correlation of graphic and text content, the pictures have great influence on junior high school students when they are presented in dynamic schematics. When the picture is presented in different positions, there are differences between the test results, the focus map, the fixation time, the fixation times and the visit time. The location of the right image (that is, the picture on the right side of the text) has a great influence on the learning of junior high school students, and the learning effect is the best. Finally, this study makes a detailed analysis of the eye movement index data in the two experiments. The rule of picture design in the teaching of PPT courseware is discussed synthetically. The conclusion of the study can give guidance to the design of PPT courseware for teachers and promote more effective multimedia teaching.
