高中化学图像语言理解现状的调查分析
发布时间：2018-07-16 19:34
【摘要】：化学图像语言贯穿于整个中学化学学习阶段。化学图像不仅在平时化学教学以及学习中频频出现,在高考试题中更是必不可少的一个环节。然而,现在有关学生化学图像语言理解方面的研究较少。因此,展开高中生化学图像语言理解的研究具有重要意义。本文的研究包括理论研究和实证研究两大部分。理论研究部分对化学图像语言有关的核心理论进行了解释,包括语言、图像语言以及化学图像分类,并分析了学生化学图像语言理解相关的影响因素并初步提出了教学策略。在理论研究的基础上,组织了关于不同学校不同年级高中学生关于化学图像理解的调查问卷活动,并对结果进行归纳和分析,由此得出了本文研究的结论及教学启发。调查研究结果表明：在化学图像语言理解水平上,重点高中学生明显优于非重点高中；男生与女生在化学图像语言的理解上并不存在明显的差异性,总体来说处于同一个水平；随着年级的增长以及学生知识的不断积累和巩固,高年级学生在化学图像语言理解水平上整体上呈现了一种缓慢增加的趋势。为提升学生对化学图像语言的理解,在教学中可以采取如下措施开展教学教学活动：选取合适的图像语言表达方式,激发学生学习兴趣；加强互动交流,引导学生发掘化学图像含义；引导学生观察,提升学生图像理解能力；引导学生分析图像,增强学生图像加工处理能力；理论联系实际,在实践中锻炼图像理解能力；时刻注重学生数学运算能力的培养；引导学生构建完善的化学知识体系。
[Abstract]:Chemistry image language runs through the whole middle school chemistry study stage. Chemistry image not only appears frequently in chemistry teaching and learning, but also is an indispensable link in college entrance examination. However, there is little research on students'understanding of chemical image language. Therefore, it is of great significance to study the language understanding of chemistry images in senior high school students. The research of this paper includes two parts: theoretical research and empirical research. In the part of theoretical study, the key theories of chemical image language are explained, including language, image language and classification of chemical image, and the influencing factors of students' understanding of chemical image language are analyzed and the teaching strategies are put forward. On the basis of theoretical research, this paper organizes questionnaire activities on chemical image understanding of senior high school students in different schools and grades, summarizes and analyzes the results, and draws the conclusion and teaching inspiration of this paper. The results show that the key high school students are better than the non-key high school students in the level of understanding of chemical image language, boys and girls do not have significant differences in the understanding of chemical image language, generally speaking, they are at the same level; With the growth of grade and the accumulation and consolidation of students' knowledge, the senior students have a slow increasing trend in the level of chemical image language understanding. In order to improve students' understanding of chemical image language, the following measures can be taken in the teaching: selecting the appropriate expression of image language, arousing students' interest in learning, strengthening interactive communication. Guide students to explore the meaning of chemical images, guide students to observe, improve students' ability of image understanding, guide students to analyze images, enhance students' ability of image processing, combine theory with practice, and exercise their ability of image understanding in practice. We should pay attention to the cultivation of students' mathematical arithmetic ability and guide them to construct perfect chemistry knowledge system.
