摘要:新课程理念给课堂教学改革带来了深刻的变化,对化学教师提出了新的、更高的要求,也给教师教学技能发展赋予了新的内容。为适应新课程改革,化学师范生应具有怎样的教学技能结构?高校如何去培养师范生的这些技能?本文借鉴各种教学技能的分类,结合化学教学的特点以及新一轮化学教学改革和教师专业化的需要,按照化学教学工作体系,设想化学师范生教学技能的结构并提出了相应的培养对策。
the teaching of experimental operation activities should be clearly unbundled, action should be standardized, especially to enable students to see the crux of the operation , through talks, so that students understand these steps, action is required what . Instructors skilled, accurate, standardized operation give students a visual beauty, which will deeply infected students, stimulate their desire to learn and imitate . For example during the purple litmus test solution dropped into chlorine experiment in addition to the correct experimental operation in addition to careful observation should guide students to experiment with this purple litmus test solution prior to instillation of the acidic solution is different phenomenon place, and then led the students to question , analyze , draw conclusions finally explain to everyone why.
Similarly, I will teach chemistry knowledge and skills into chemistry concepts chemistry lecture skills. Because high school chemistry concepts involved is extremely rich , so that the teaching of chemistry in which occupy a considerable proportion. Chemistry Teaching mainline structure of matter , and then the main line above interspersed substance composition, properties of matter , as well as physical changes between other aspects of knowledge . In the process of organizational knowledge is based on a kind of simple to complex, from shallow to deep logical sequence organized. Then let the students to grasp these concepts is a very important part . So chemistry concepts taught skills directly determines the level of teaching quality . Teaching skills mainly includes the following aspects , first intuitive teaching skills , teaching skills of a second variant , the third heuristic teaching skills , the fifth definition of the concept of skill , practice and consolidate the Sixth conceptual design skills . Which visual teaching instructor asked them to be able to compare the skilled application of modern multimedia devices. Skills training to teach the concept of teaching contents should make clear what are the chemical concepts . Chemistry Teaching mainline structure of matter , and then the main line above interspersed substance composition, properties of matter , as well as physical changes between other aspects of knowledge . In the process of organizational knowledge is based on a kind of simple to complex, from shallow to deep logical sequence organized. Secondary chemical properties of matter content for the presentation of roughly the same logic , for example, we finished the nature of chlorine to chlorine students summed up the nature of their learning in this chapter and the next logical order to learn the nature of other substances analogy , the formation of a scientific way of thinking and understanding of concepts can be on a new level.
Chemistry concepts taught chemistry skills are taught basic skills , skills are taught chemistry chemistry concepts taught in a higher level of skills in chemistry , we can understand the linkages between the various concepts . So talk about a good chemistry concepts is a prerequisite for good chemistry . Even so , however chemistry teaching also has his own characteristics , we must first understand the basic concepts , then the concept of life linked to inspire students to question the thinking and let each student a deep understanding of these principles is correct. For example, in explaining the original battery can be an entry po
