Abstract


In this study, cognitive psychology theoretical guidance to junior and senior students as research subjects , through empirical study investigated the chemistry experiment in problem-solving types of errors and wrong reasons , draw students in the experimental problem solving existing problems and differences , and to explore the students to solve problems that exist in chemical experiments obstacles and reasons for the differences . Further optimization of classroom teaching experiment design , selection of effective experimental problem solving strategies to make classroom teaching without formality , on an experimental basis so that students construct knowledge consciously promote experimental problem solving skills , play experimental teaching educational function . In this study, the following two aspects : 1 , the use of self \2 , the use of self \Total experiment selected 157 subjects , of which 99 were sophomore , third year 58 people, each grade in accordance with the student's academic level is divided into three groups. Final conclusions are as follows : 1, knowledge barriers is the main reason leading student errors . 2, the complexity of the issues that affect students' problem solving chemistry experiment . 3 , the novelty of the problem situation and presentation of information for students to solve problems affecting chemistry experiment . 4, the implied conditions for students to solve problems affecting chemistry experiment . Based on the findings , we propose in the teaching process can take the following measures to promote student development of chemistry problem solving : 1. Orderly arrangement of knowledge , to form a good cognitive structure (2) training in the use of effective problem solving , problem solving process to give students a proper trail Tip 3 . improve experimental teaching methods to provide students with more hands-on opportunities
