Based Activities - Construction Of The "amount Of Substance The Instructional Design And Practice

This study is in the background of new course on the "construction activity" research on the teaching mode of practice. For Chemistry concept teaching we cannot simply teach them, but attention should be paid in the process of concept formation, by arousing students ' interest in learning, changing the way students learn, to create a learning environment for students, students in the activities of autonomous complete construction of the concept, developing the student's logical thinking ability, is conducive to improving the scientific literacy of the students. This is advocated by the new courses. At this point I have learn from predecessors on the basis of research results, guided by relevant theory, concepts in high school chemistry teaching design and practice in teaching research, to explore "construction activities" that the adequacy and effectiveness of a teaching strategy.I turn first to the "amount of substance" research status, activity theory, constructivism, through a system of inspection and analysis, providing a theoretical basis for teaching design. The second step, senior high school students of the first concept exploration for the teaching of design analysis, on chemical teaching of high school students, teacher interviews were conducted. By high school students interview further clearly insufficient when a student learning puzzles and, through interview with clear knowledge of heavy and difficult to teachers, teaching strategies and techniques. Teaching design work to lay a good foundation for the future..Practice stage, researchers of high school chemistry "amount of substance" this core concept by "construction activity" teaching. After the completion of teaching practice, through the analysis of experimental and control classes, student interviews, and half-term number of tracking this teaching model has significant effect is observed. Final adoption of the research to the inspiration I was: teaching should pay attention to creating question situation teaching design to be fully prepared in the course "learning activities"; generated to focus on the students ' knowledge in the teaching process.
