基于3C-FIAS与音频波形的化学优质课教学语言研究

Research on Teaching Language of Excellent Chemistry Course Based on 3C-FIAS and Audio Waveform

基于现代化学课堂教学互动分析系统(3C-FIAS)和音频波形分析系统,以6堂浙江省高中化学优质课为参考样本,建立化学优质课的3C-FIAS教学行为变量参数,从课堂语言、课堂活动、课堂氛围、课堂节奏4个维度分析变量参数的适用性、科学性和实用性,同时根据授课教师音频波形图中高能片段出现的位置、内容和频次等进行教学语言评析,发现6名教师虽然接纳学生回答的方式、调动课堂气氛的方法各不相同,但都能游刃有余地把握课堂节奏,运用语音语调的技巧也较为相似。为了提高化学课堂教学的质量、创新授课的风格和方式,化学教师可以尝试从以下方面努力:提升提问水平,讲究问答艺术;合理运用素材,把握使用程度;加强师生交互,追求互动艺术;重视语音技巧,讲求语言艺术。

Based on the analysis system of the FIAS based on contemporary Chemistry class(3 C-FIAS)and audio waveform,six high-school excellent Chemistry course of Zhejiang Province were selected as reference samples.The 3 C-FIAS teaching behavior variable parameters of excellent Chemistry courses were novelty established in this work.The applicability,scientificity,and practicability of the variable parameters were analyzed according to the four dimensions including course language,course activities,course atmosphere,and course rhythm.At the same time,according to the position,content and frequency of high-energy fragments in the audio waveform of the teachers,the teaching language was evaluated and analyzed.It was found that the six teachers had different ways to accept students’answers and mobilize the classroom atmosphere,but they were all able to grasp the classroom rhythm with ease and had similar skills in using pronunciation and intonation.In order to improve the quality of Chemistry classroom teaching and innovate the teaching style,Chemistry teachers can try to make efforts from the following aspects:improve the level of questions and pay attention to the art of question answering;reasonable use of materials and pay attention to the degree of use;strengthen teacher-student interaction and pursue interactive art;attach importance to phonetic skills and language art.
