根据化学教学的特点,教师可从以下几方面加强对学生能力的培养 一、记忆能力的培养 记忆是进行学习、获得知识和技能的必备条件。要增强和提高学生记忆能力,在教学中教师要做到:(1)要求学生充分利用视觉器官注意观察,抓住事物特征,切忌粗枝大叶看一遍。(2)利用必要的重复来加深对记忆事物的印象。如教师多次重复提问,学生反复回答或师生通过叙述再现等方法加强对问题的记忆。(3)揭示规律,理解记忆。告诉学生 相似文献

新课标要求我们在教学上的培养目标是培养高素质的人才,培养动手能力和理论能力都强的人才.这就需要首先培养起学生对于化学的兴趣,只有这样学生才会自主的学习,才能够提高自身的动手能力.兴趣是最好的老师,当学生对学习化学产生了兴趣,自然就会在学习中用心去感受,这样学生们对化学知识的理解就会更深.一、运用情境教学方法,增加学生的兴趣良好学习习惯的培养不仅仅是利于学生化学成绩 相似文献

This article describes a study conducted in Israel which focused on how learning industrial chemistry case studies affects
students' perceptions of their classroom learning environment and their interest in chemistry studies. The goal of the study
was to determine the effects of industrial case studies on students' perceptions of chemistry in general, and industrial chemistry
in particular. Information on students' perceptions was gathered from a learning environment inventory specifically developed
for this study. It was observed that industrial chemistry case studies helped in providing students with a relevant picture
of chemistry in general and their chemistry studies in particular. It was also found that teachers who had attended an intensive
training workshop were the most successful in presenting the relevance of chemistry in the case studies. These teachers also
were more successful in raising students' awareness of the social implications of chemistry studies. Furthermore, their students
had a better awareness of the contribution made by chemistry studies to their preparation as future citizens and for a possible
career in chemistry. These findings have important implications for any decisions about whether to make industrial chemistry
case studies obligatory for students who major in chemistry. There are further implications regarding the content and learning
strategies to be used for the professional development of science teachers in general and chemistry teachers in particular.

Peers, family, mentors and the media may influence students’ attitudes towards chemistry and their intention to enrol in tertiary chemistry courses. In this paper we report on an investigation of the perceptions students hold about their associates’ attitudes towards chemistry and chemists. Data were gathered from interviews with 37 tertiary chemistry students, for whom chemistry had differing roles in their degree. The data suggest that although many of the students’ associates subscribe to stereotypical images of chemistry and chemists, students’ choices of enrolment are predominantly based on their own previous experiences. 相似文献

论化学教师的PCK结构及其建构 总被引：1，自引：0，他引：1
梁永平 《课程.教材.教法》2012,(6):113-119
教师专业发展的核心问题就是发展他们的PCK。化学教师的PCK主要包括基于化学科学理解的化学学科知识、关于学生理解化学的知识、关于化学课程的知识和化学特定课题的教学策略及表征的知识。教师的PCK是在实践中建构和发展的。PCK的发展是一个非线性的、螺旋发展的动态的过程。化学教师PCK建构的基本策略是:形成促进PCK发展的教学思维方式,提升对化学科学的理解水平,关注学生对于化学的理解,发展化学课程知识,提高整合转化能力,多渠道丰富PCK资源库。 相似文献

Context-based curriculum reforms in chemistry education are thought to bring greater diversity to the ways in which chemistry teachers organize their teaching. First and foremost, students are expected to perceive this diversity. However, empirical research on how students perceive their teacher's teaching in context-based chemistry classrooms, and whether this teaching differs from traditional chemistry lessons, is scarce. This study aims to develop our understanding of what teaching looks like, according to students, in context-based chemistry classrooms compared with traditional chemistry classrooms. As such, it might also provide a better understanding of whether teachers implement and attain the intentions of curriculum developers. To study teacher behaviour we used three theoretical perspectives deemed to be important for student learning: a content perspective, a learning activities perspective, and an interpersonal perspective. Data were collected from 480 students in 24 secondary chemistry classes in the Netherlands. Our findings suggest that, according to the students, the changes in teaching in context-based chemistry classrooms imply a lessening of the emphasis on fundamental chemistry and the use of a teacher-centred approach, compared with traditional chemistry classrooms. However, teachers in context-based chemistry classrooms seem not to display more ‘context-based’ teaching behaviour, such as emphasizing the relation between chemistry, technology, and society and using a student-centred approach. Furthermore, students in context-based chemistry classrooms perceive their teachers as having less interpersonal control and showing less affiliation than teachers in traditional chemistry classrooms. Our findings should be interpreted in the context of former and daily experiences of both teachers and students. As only chemistry is reformed in the schools in which context-based chemistry is implemented, it is challenging for both students and teachers to deal with these reforms. 相似文献

There are many factors that shape students’ attitudes toward science, technology, engineering and mathematics. This exploratory study of high school students examined the effect of enriching chemistry with math on chemistry students’ attitudes toward math and careers involving math. To measure student attitudes, a survey was administered before and after the 18-week chemistry class; results from the chemistry class were compared to survey results from students in an elective science class that did not emphasize mathematics. At the end of the 18-week period, only the chemistry students exhibited more positive views toward their abilities in mathematics and careers that involve mathematics, as compared to their views at the outset of the course. To ensure that chemistry mastery was not hindered by the additional emphasis on math, and that mastery on state end-of-course examinations reflected knowledge acquired during the math-intensive chemistry class, a chemistry progress test was administered at the start and end of the term. This exploratory study suggests that emphasizing mathematical approaches in chemistry may positively influence attitudes toward math in general, as well as foster mastery of chemistry content. 相似文献

The purpose of this study was to model the relationship between pre-service chemistry teachers’ epistemological beliefs and their preference to use constructivist-learning environment in their future class. The sample was 125 pre-service chemistry teachers from five universities in Turkey. Two instruments were used in this study. One of the instruments was constructivist-learning environment scale developed by Taylor, Fraser and Fisher. The other instrument was Epistemological Questionnaire (EQ) developed by Schommer. In order to analyse data, Structural Equation Modelling was conducted by using LISREL 8.7. The results provided evidence for the good fit of the hypothesised model. Pre-service chemistry teachers’ epistemological belief scores were found to be correlated to their constructivist-learning environment scale scores with the value of .35. This study revealed that pre-service chemistry teachers with sophisticated epistemological beliefs favoured constructivist-learning environment in their future class. 相似文献
