化学课在工科中专学校是一门基础课,化学学科的特点是以实验为基础,培养学生动手操作能力,促进学生创造性思维的发展。本文根据中专学生的实际情况,结合中专基础化学学科特点,从中专化学教学的实际出发,在中专化学课堂教学中探索如何将传统的教学手段与现代化教学手段有机地结合,适时、适度、适量地将多媒体技术应用于课堂教学中。 本文依据建构主义的理论,遵循“学教并重”教学指导思想,采用了准实验法、问卷调查法、访谈法及观察法对在中专化学课堂教学中应用多媒体技术的切入点、原则及时机进行了研究,并得出以下结论:1、根据教学目标和教学对象的特点,将多媒体技术适时、合理、灵活的与传统的教学手段相结合,发挥各自的优势,相辅相成,会在中专化学教学中激发学生的学习积极性。2、多媒体应用于教学可以突破传统教学不能解决或解决得不好的难点内容,可以加深学生对化学知识的理解。3、在中专基础化学教学中把多媒体技术与传统教学手段有机结合起来,能够优化中专化学课堂教学的效果。4、多媒体技术在中专化学课堂教学中应用的适时性表现在它是否能根据教学目标和学习对象的特点,在符合化学科学的科学性和教学规律的原则下,把握好适合的时候、时机、时间、时限、时效和实效。
Chemistry is an essential curriculum in the Technical Secondary School of engineering. Its characteristic is cultivating students" practice ability and promoting the improvement of student"s creative thought on the basis of experiments. According to the facts of the technical secondary school students and chemistry teaching, this paper combined with the characteristic of chemistry curriculum probes into how to realize the organic integration of traditional teaching means and modern teachings means, and apply multi-media technique to teaching timely, reasonably and properly in the chemistry classroom teaching of the Technical Secondary School.In terms of the Constructivism Learning Theory and following the guide idea of "pay equal attention to learning and teaching", the paper adopts the methods such as informal experiments, questionnaire, interview and observation to study the cut-in point, principle and time of applying multi-media technique in chemistry teaching. The research has come to a conclusion: 1. According to characteristic of teaching target and object, the way of integrating multi-media technique with traditional teaching means timely, reasonably and flexibly and exerting each advantage supplement each other to achieve supplement each other would arouse the enthusiasm for study of students on chemistry lessons. 2. The application of multi-media technique can break through difficulty that couldn"t be settled or solved drastically by traditional teaching so that students have a further knowledge of the chemistry. 3. The organic integration of multi-media technique and traditional teaching means can optimize the chemistry teaching effect. 4. The timely application of multi-media technique in the chemistry classroom teaching of the Technical Secondary School shows in whether it can grasp the proper time, opportunity, time limit, time effect and actual effect according to characteristic of teaching target and object and on the principle of the chemistry"s science and teaching law.
