落实新课程,开展研究性学习,目的是为了适应新的课程改革,教师要把观念从化学教学转变为化学教育.课程改革要求教学方式不断更新,科学手段不断完善,拓宽教学思路,发挥化学学科优势.高中化学新课程则是要帮助学生来主动构建自身在化学中所需要的基本知识和技能,同时还要进一步对化学学科的特点进行了解,并加深对物质世界的认识;这样有利于学生探究科学和体验科学,加深学习科学的基本方法,对科学本质上的认识,增强自身创新精神和实践的能力;有利于学生形成科学的自然观和严谨求实的科学态度,那么,对于新课程的思想、理念与实施,我们如何反思长期以来惯用的化学教学模式,如何构建适合新课程标准要求的化学模式.下面我们谈谈在高中化学教学模式创新中具体实施的一些做法. 相似文献

新课程改革背景下,高中化学教学要求有了较大的改变,高中化学教学更为注重对学生思维能力,学生探究性精神以及化学学科观念的培养与建设.新课程背景下,高中化学课该怎么上,该采取何种教学模式进行高中化学课堂教学,成为每一位化学教师想要弄清的问题.笔者认为在新课程背景下,在高中化学教学过程中实施"问题驱动"教学模式不仅能够有效地调动学生的思维,还能够培养学生的探究性精神,帮助学生建立化学学科观念,不失为一种十分有效的教学模式.本文就如何在高中化学教学中构建问题驱动教学模式进行实践与探索.一、结合生活实际构建化学问题情境 相似文献

Scientific writing is related to the practice of communicating scientific knowledge. This study treats scientific writing as a social practice, taking as its premise the notion that participating in related activities such as reading, peer evaluation, and discussion would positively affect the competence of students’ scientific writing, by developing their epistemic cognition regarding scientific knowledge communication and legitimation. An empirical study was conducted with twenty-two Chinese undergraduate students to test this premise. These students were majoring in chemistry and undertook a researcher-designed intervention course (Advanced Organic Chemistry Experiment), which embodied the integrated strategy of reading, peer evaluation, and discussion on scientific writing. Based on data pertaining to those students’ performance in terms of the normativity, objectivity, and logicality of scientific writing drawn from a previous study by the current author (Deng, Kelly, & Xiao, 2019. The development of Chinese undergraduate students’ competence of scientific writing in the context of advanced organic chemistry experiment course. Chemistry Education Research and Practice, 20, 270–287), alongside data drawn from students’ written texts in reading reflections and on-line discourse related to peer evaluation and discussion, this study claimed that the tasks of reading, peer evaluation, and discussion were seen gradually to lead to the development of Chinese undergraduate students’ greater competence in scientific writing regarding the synthetic experiments of organic chemistry. 相似文献

论数学心理观的历史性和必然性 总被引：1，自引：0，他引：1
笔者通过对心理活动的数的性质进行回顾和概括，提出数学心理观作为心理的认识观之一是心理科学发展的历史的必然，并从数学心理观的侧面说明理论心理学在反对科学主义和实证主义、提倡人文科学精神的同时，也重视倡导科学的实验方法。 相似文献

国内外科学教育界普遍认为科学实践与科学认识的协同发展是培养学生科学素养的重要途径。本文以化学学科为例,对科学实践与科学认识的内涵进行了解构,认为科学实践由“一般科学实践”“学科实验活动”“学科能力活动”组成,科学认识由“学科核心知识”“学科认识方式”组成。在阐述科学实践与科学认识协同发展必要性的基础上,提出了促进科学实践与科学认识协同发展的四维模型,对促进二者协同发展的教学设计提供了建议。 相似文献

We contend that Chemical education proposals for changing the conception of chemistry literacy should include making explicit the relationship between chemistry as science and chemistry as technology. The potential for increasing students' confusion about what these interconnected activities involve is significant. In this paper we illustrate the importance of distinguishing between scientific and technological activities by explaining the events and processes that are occurring, firstly between material objects (instruments, machines) and practical activities and ideas; and secondly between ideas (theory) which may be called explanations and those that we call knowhow. We illustrate this by exploring the controversy in the development of chemical theory in history - the supposed isomerism of ethane. The additional purpose of this article is to highlight the importance of the history of chemistry in the education of chemists. 相似文献

This study aimed to investigate the effects of inquiry-based laboratory activities on high school students’ understanding of electrochemistry and attitudes towards chemistry and laboratory work. The participants were 62 high school students (average age 17 years) in an urban public high school in Turkey. Students were assigned to experimental (N?=?30) and control groups (N?=?32). The experimental group was taught using inquiry-based laboratory activities developed by the researchers and the control group was instructed using traditional laboratory activities. The results of the study indicated that instruction based on inquiry-based laboratory activities caused a significantly better acquisition of scientific concepts related to electrochemistry, and produced significantly higher positive attitudes towards chemistry and laboratory. In the light of the findings, it is suggested that inquiry-based laboratory activities should be developed and applied to promote students’ understanding in chemistry subjects and to improve their positive attitudes. 相似文献

The objective of this study is to facilitate progressive transitions in chemistry teachers understanding of nature of science in the context of historical controversies. Selected controversies referred to episodes that form part of the chemistry curriculum both at secondary and university freshman level. The study is based on 17 in-service teachers who had registered for an 11-week course on ‘Investigation in the teaching of chemistry’ as part of their Master’s degree program. The course is based on 17 readings drawing on a history and philosophy of science perspective with special reference to controversial episodes in the chemistry curriculum. Course activities included written reports, class room discussions based on participants’ presentations, and written exams. Based on the results obtained it is suggested that this study facilitated the following progressive transitions in teachers’ understanding of nature of science: (a) Problematic nature of the scientific method, objectivity and the empirical basis of science; (b) Myths associated with respect to the nature of science and teaching chemistry; (c) Science does not develop by appealing to objectivity in an absolute sense, as creativity and presuppositions also play a crucial role; (d) The role of speculation and controversy in the construction of knowledge based on episodes from the chemistry curriculum; (e) How did Bohr confirm his postulates? This goes beyond the treatment in most textbooks; (f) Differentiation between the idealized scientific law and the observations. It is concluded that given the opportunity to reflect, discuss and participate in a series of course activities based on various controversial episodes, teachers’ understanding of nature of science can be enhanced. 相似文献

Many studies have used the potential of computer games to promote students’ attitudes toward learning and increase their learning performance. A few studies have transformed scientific content into computer games or developed games with scientific content. In this paper, we employed students’ common misconceptions of chemistry regarding the properties of liquid to develop a computer game. Daily life situations and everyday phenomena related to the chemical understanding of the properties of liquid were also taken into account. Afterward, we applied a process-oriented, inquiry-based active learning approach to implement the game in a Thai high school chemistry course. We studied the implementation of a game-transformed inquiry-based learning class by comparing it to a conventional inquiry-based learning class. The results of this study include aspects of students’ conceptual understanding of chemistry and their motivation to learn chemistry. We found that students in both the game-transformed inquiry-based learning class and conventional inquiry-based learning class had a significantly increased conceptual understanding of chemistry. There was also a significant difference between the gains of both classes between the pre- and post-conceptual understanding scores. Moreover, the post-conceptual understanding scores of students in the two classes were significantly different. These findings support the notion that students can better comprehend chemistry concepts through a computer game, especially when integrated with the process-oriented, inquiry-based learning approach. The findings of this study also highlight the game-transformed inquiry-based learning approach’s support of students’ motivation to learn chemistry.
