Research On Teaching Effectiveness Of Chemical Experiment In Junior Middle School

In the long-term teaching practice, education workers have been after is highly effective classroom teaching. How to improve the class The effectiveness of class teaching, improve the classroom teaching quality is a hot spot in current research.Chemical experiment is an important part of chemistry teaching content, is the most realistic and chemical image carrier, the most vivid, the most effective teaching. Although the literature of effective teaching and chemical experiment teaching is very rich, but from the perspective of effective teaching of junior middle school chemistry experiment research is rarely. Based on this, the author decided to carry out Junior middle school chemical experiment teaching effectiveness research.This study based on the new standard, the effective teaching and constructivism, advance organizer, under the guidance of the theory of effective teaching existing in the definition of some common content, to promote the development of the students from the teachers’ teaching behavior the perspective, defining the effective teaching of junior middle school chemical experiment. Through a questionnaire survey of students to understand the current situation of junior middle school chemical experiment teaching, and the situation about students’ learning and teachers’ teaching two dimensions analysis of the results of the investigation, summarizes the factors hindering the research on the experimental teaching to achieve goals, and targeted put forward the corresponding strategies: the zetetic experiments in a timely manner, the "force-feeding" to "heuristic" experimental teaching mode, experimental scheme optimization, the experiment of life, the selective use of multimedia technology, develop pluralistic evaluation, application of the corresponding teaching strategies to improve the effectiveness of the junior middle school chemical experiment teaching.
