Practical Research On The Integration Of ’Teaching,learning And Evaluation’ In Middle School Chemistry Based On SOLO Classification Theory

In order to effectively implement the core quality of chemistry discipline of Chinese middle school students,the new curriculum standard puts forward the teaching concept of "teaching,learning and evaluation" integration,and expounds the importance of "teaching,learning and evaluation" integration in chemistry education and teaching.SOLO classification theory is a method of evaluating students’ academic performance,which can guide teachers to divide students’ thinking levels into five different structural levels:pre-structural,single point structure,multi point structure,correlation structure,and abstract extension structure and then guide teaching design and practice to further help students find their "closest development zone",mobilize the learning enthusiasm of students with different scientific thinking,and improve students’ thinking level and cognitive level,promote the formation of students’ good cognitive structure and develop students’ core quality of chemistry.In order to better implement the integration of "teaching,learning and evaluation" in teaching practice,based on the SOLO classification theory,first of all,combs the research progress of the SOLO classification theory and the integration of "teaching,learning and evaluation" by using the literature analysis method.Secondly,based on the analysis of the new curriculum standards and teaching materials,the contents of "sodium and its compounds" in the first volume of compulsory high school chemistry in the New Education Edition are sorted out,and the hierarchical structure of knowledge level is divided under the guidance of SOLO classification theory.Thirdly,the questionnaire method is used to understand the current situation of chemistry learning of senior high school students from the perspective of students,and the interview method is used to understand the current situation of middle school chemistry teachers’ integrated teaching design and implementation of "teaching,learning,and evaluation" based on SOLO classification theory from the perspective of teachers,and analyze the problems existing in the current middle school chemistry teaching: a few students’ interest in chemistry learning and the efficiency of chemistry classroom is not high enough,it is believed that teachers cannot provide targeted feedback to help students adjust their learning styles in time;due to teaching time and other force majeure factors,teachers cannot effectively implement the integration of "teaching,learning and evaluation".Finally,based on the above findings,taking "sodium and its compounds" as an example,this paper designs three teaching cases of "teaching,learning and evaluation" integration of senior high school chemistry based on the SOLO classification theory,which are "active metal element-sodium","sodium oxide of sodium-sodium oxide and sodium peroxide","sodium carbonate and sodium bicarbonate",it also applied the experimental research method to carry out teaching practice in two parallel classes with the same level of chemistry.Through the analysis of teaching results,it was confirmed that the integration of "teaching,learning and evaluation" and the integration of SOLO classification theory were beneficial to improve students’ self-confidence,stimulate students’ interest in chemistry learning,and promote the development of students’ thinking and core quality of chemistry discipline.
