Research On The Design And Application Research Of Micro-lecture In Junior Chemistry Teaching

Nowadays, with the rapid development of information technology, teaching means and methods has become more abundant and diverse.Wherein the micro-lecture (Micro Video Course for short) is a new thing in education under the information age. The core resources of micro courses, micro-video, mix together text, pictures, music, animation and other elements of fusion, appear as a single point of knowledge for all learners to learn anytime, anywhere, with its unique advantages in education has attracted more and more attention.I chose the " Research on the Design and Application research of micro-lecture in Junior Chemistry Teaching", aimed at combining the characteristics of chemistry, taking the advantage of micro-lecture, mix together chemistry class, micro lecture with the existing education mode, with the purpose of playing the best of classroom teaching. Research is divided into two parts, theoretical research and applied research, in the theoretical research complete these tasks:(1) From the analyzing of current research, we know origin of the micro-lecture and the reasons why it get wide attention.we define the concept of micro-lecture, clear the characteristics of the micro-lecture. (2) Combining the characteristics of junior high school chemistry, micro-lecture of junior high school chemistry is unique, thus comes unique micro-lecture type of junior high school chemistry lessons.(3)According to the design principles of micro-lecture and the analysis of the subject and the students,1 designed the production process of chemistry micro-lecture, expounded the advantage of micro-video recording software;(4) Under the guidance of cognitive load theory, constructivist theory, I produced three junior high school chemistry class lesson examples,that is experimental demonstration class, reasoning and calculus class. (5) Proposed currently three models of the applies of micro-lecture-flipped classroom, embedded micro-lecture classroom teaching, students1 extracurricular learning. In the practice, some major work was completed:(1) Do comparative analysis experiments in two cognitive levels similar classes, applied the micro-lecture into teaching practice. Take the lessen<air> for example,Use flip classroom model using micro-lecture resources, analysis the process and make a summary. (2)Using questions testing in the experimental class and the control class, compare the influence of the use of micro-lecture. (3) With questionnaires survey the effects after the application of micro-lecture.(4)With interviews of the experimental class teachers about the experience and evaluation of the application of micro lecture teaching investigation, which were analyzed and summarized.In practice, the study found that the experimental class student achievement improves significantly, they are more interesting in Chemistry, self-learning ability was improved, information processing and problem solving-ability has been raised. All these indicate that there is a practical effect of applying of the micro-lecture in junior high school chemistry teaching.At last I summarized the study, make a few suggestions for the micro-lecture resource development and application of the micro-lecture. I hope in the future the applications of micro-lecture will be more complete and perfect.
