Current Situation And Development Strategies Of Chemistry Criticalthinking For High School Students

The current situation of senior high school students’ critical thinking in chemistry had been explored and the corresponding development strategies had been put forward. The present work had been focused on the following two aspects:In the "basic research" part, critical thinking at home and abroad had been summarized through the means of literature. Domestic summary Involved four aspects on critical thinking as follows, the formulation of measuring tool, the investigation on the level of thinking, the influence factors and the strategy of the cultivation. Foreign summary listed the development situation of critical thinking according to time order. Overall, the foreign study had been started earlier and more in-depth than domestic study. However, domestic research had been paid more and more attention in recent years.In the "supporting study" part, the core concept of "critical thinking" had been teased through the means of literature and my own definitions had been put forward. In addition, closely connected with critical thinking, development rules of teenagers thinking and critical education theory had been elaborated.In the "core study" part, first,a survey of the use of "Critical Thinking Disposition Scale" critical thinking of students conducted a survey, wanted to study grade, gender, and class type(specialty classes and non-specialty classes) and class level(key classes and ordinary classes) on critical thinking, the survey showed no significant difference between male and female high school senior grade students critical thinking, Middle School boys did better than girls; There was no significant difference between specialty classes and non-specialty classes.In senier two and three,the students in special class did better job than those in non-specialty classes. Key classes in three grades performed better than ordinary classes.The level of critical thinking of senior one and senior two was higher than that of senior three.Overall, the measured critical thinking of students lied in middle and upper levels, but then based on "Critical Thinking Disposition Scale" questionnaire,chemistry students critical thinking ability is poor, which needs to be improved. Secondly,based on the results of the questionnaire survey, combined with interviews and classroom observation, the factors affecting critical thinking and training strategies were analyzed.Factors affecting the development of students’ critical thinking were many externalfactors induding socio-cultural factors, educational institutions and educational patterns and other factors, while internal factors were the student’s own development, including the formation of critical motivation, knowledge and personality reserves.Finally, according to the combination of factors, the strategy of students’ chemistry critical thinking was summarized. From the teachers’ point of view, teachers should to change teaching ideas, change teaching mode, and teached students to create a harmonious atmosphere of democracy; They also payed attention to the rational design of teaching case, focusing on the importance of experimental teaching. From the perspective of students, they needed to strengthen their motivation and knowledge critical reserves, and continued to improve the students’ personality cultivation.
