| The new course reforms emphasize the teachers’ leading role and the students’ dominantposition. The aim is to promote students’ active learning, and the purpose of comprehensive,healthy and harmonious development. The main channel of education is classroom activity.Moreover, lead-in is the first link of the classroom teaching. A wonderful lead-in is anessential part of success in teaching, a golden key to motivate students’ interest and a measureto guide students into knowledge palace. It stimulates students’ interest and thinking, thus itenables students to learn the new lesson concentratedly, actively, and naturally.This dissertation combines investigation with theoretical knowledge for middle schoolphysics. Some design principles and methods for art of lead-in are researched based onlead-in status on first-line teaching practice. Multidimensional interactive lead-in model isconstructed for first-line teaching, and some requests to teachers and students for lead-in arediscussed. Finally, teacher-student cooperation model is proposed based on art of lead-inunder new course reforms.Six parts are divided in this dissertation. The chapter I describes the research background,research status and methods under new course reforms. Art of lead-in for middle schoolphysics teaching is proposed. The chapter II studies the theory for art of lead-in, andintroduces a comprehensive art of lead-in to middle school physics teachers. The chapter IIIsurveys the lead-in status of middle school physics teaching through interview andquestionnaire, and analyzes current problems in middle school physics teaching. Art oflead-in is summarized to six aspects including lead-in design, lead-in contects, lead-inmethods, lead-in time, students’ participation and teachers’ factors. The chapter IV proposedthe design principles and methods for Art of lead-in in middle school physics teaching basedon lead-in theory and characteristics of the new curriculum. The chapter V constructs amultidimensional interactive lead-in model to middle school physics projects. Aimed toteaching practice, some teaching activities are explored for multi-dimensional interactivelead-in model. Based on teaching practice, some requests to teachers and students for lead-inare researched. Moreover, teacher-student cooperation is proposed based on art of lead-inunder new course reforms. Some results and prospects are shown in chapter VI. Based on art of lead-in, middle school physics teachers improve their theoretical level andclassroom activities ability. Moreover, art of lead-in can improve classroom teaching effects,and make students more motivated to learn physics knowledge. The presented methods areworthy of being used in teaching reforms and researches and it offers its reference value formiddle school physics teachers. |
