关于高师院校化学专业实验课程体系改革的思考 总被引：1，自引：1，他引：1
推进高师院校化学专业实验课程体系的改革,打破"四大化学"的界线,以实验基本操作技术为主线,在4年中分别开设化学实验基本技术、化学中级实验技术、综合性实验和设计性实验4门课程,使实验课程教学具有独立的课程体系,既体现了实验教学和理论教学的等同地位,也强化了综合性、设计性实验的开设过程,充分发挥了实验教学对学生综合实验能力、创新意识的培养功能. 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.

初三化学实验正处于学生探索化学奥秘,追求真理,实事求是的启蒙阶段,对初学化学者的吸引力不言而喻;同时,化学实验作为化学学科和化学教学的基础,在化学教育教学中的地位不可替代。目前,毕节市七星关区四中、七中、十二中、十三中的化学实验教学设备设施已基本建成,部分学校实验教学正有条不紊地进行。但化学实验教学不受重视,开展难,仍然是大多数学校存在的瓶颈。着力加大实验教学投入,改变教师教学观念,势在必行。 相似文献

This paper concerns Bildung-oriented chemistry education, based on a reflective and critical discourse of chemistry. It is contrasted with the dominant type of chemistry education, based on the mainstream discourse of chemistry. Bildung-oriented chemistry education includes not only content knowledge in chemistry, but also knowledge about chemistry, both about the nature of chemistry and about its role in society. In 2004 Mahaffy suggested a tetrahedron model based on Johnstone’s chemical triangle. The latter represents the formal aspects of chemistry teaching (macro, submicro, and symbolic) and the top of the tetrahedron represents a human element. In the present paper the following subdivision of the top is suggested (starting from the bottom): (1) applied chemistry, (2) socio-cultural context, and (3) critical-philosophic approach. The professional identity of the Bildung-oriented chemistry teacher differs from that of the chemist and is informed by research fields such as Philosophy of Chemistry, Science and Technology Studies, and Environmental Education. He/she takes a socio-critical approach to chemistry, emphasising both the benefits and risks of chemistry and its applications. 相似文献

The aim of the study was to investigate prospective gymnasium teachers' conceptions of chemistry learning and teaching. Data were collected through individual interviews with nine prospective teachers at one German university. Phenomenography served as the methodological framework for the study. The findings revealed that chemistry learning is conceptualized as gaining knowledge, problem-solving and constructing personal understandings; and that chemistry teaching is conceptualized as transferring knowledge, problem-posing and interacting with pupils. The majority of the prospective teachers' conceptions of learning chemistry were considered reproductive rather than constructive and their conceptions of chemistry teaching were viewed as facilitating reproductive learning. Comparisons of the dominant conceptions of learning chemistry and teaching chemistry held by each prospective teacher revealed mixed support for the assumption that if one holds a reproductive (or constructive) conception of teaching, then (s)he will also hold a reproductive (or constructive) conception of learning. Support for the assumption was found in the reproductive-oriented relationship between conceptions of learning chemistry as gaining knowledge and of teaching chemistry as transferring knowledge, but not found in the relationships between learning chemistry as problem-solving and teaching chemistry as problem-posing and between learning chemistry as gaining knowledge and interacting with pupils. 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
