Application Of "Teaching-Learning-Assessment-Assistance" Integration Model In Chemistry Teaching In Junior Middle School

The traditional teaching evaluation mode is that teachers only evaluate students 'performance in the semester or academic year according to the results of the exam,which has a certain monicity.Compared with the single traditional teaching evaluation mode,the integrated mode of "teaching-learning-evaluation-help" pays more attention to the use of modern teaching tools to realize the diversification and comprehensiveness of teaching process evaluation and formation evaluation.The new curriculum standard requires students to develop all-round way,which requires changing from traditional academic performance evaluation only to all-round and diversified evaluation of students,but also includes students ' self-evaluation.In the 1990 s,foreign studies on the integration of "teaching-learning-evaluation" have appeared,and have achieved some results.With a new round of curriculum reform and teaching tools,weifang vigorously promote and implement the "teaching-learning-evaluation" integrated teaching mode at the same time,in order to give full play to the role of modern information technology and modern teaching tools,and further put forward the "teaching-learning-evaluation-help" integrated teaching mode,the tablet computer as an important teaching auxiliary tool,the integration of modern education technology and education teaching depth.Teachers formulate different levels of evaluation measures through the tablet according to the basis of different students,and more easily and quickly understand how the students learn over a period of time through the data analysis on the tablet.This research is based on the theory of the theory of metacognitive theory,constructivist theory and information processing theory,based on the core chemistry literacy,based on the research on the integrated teaching of "teaching-learningevaluation" at home and abroad,the integrated teaching mode of "teaching-learningevaluation-help" is applied to the teaching process of chemistry in the third grade.We implement the integrated teaching of "teaching-learning-evaluation-help" through the unit design of the Air Around Us and the Chemistry of Metal and Solbility.In the process of teaching implementation,through the analysis of curriculum standard,textbooks,teaching situation,establishing teaching objectives,evaluation task design,and specific teaching activities design according to the specific evaluation tasks.In the whole teaching process,the tablet computer-aided method is adopted to promote the integrated teaching of teaching evaluation.The teaching practice results show that the implementation of the "teachinglearning evaluation-help" integrated teaching model helps the teachers to pay attention to the students ' learning at any time,and help the students to recognize the learning situation of this stage,their own shortcomings,and the gap with other students.Using tablet computers,real-time communication between teachers and students,students can conduct mobile learning anytime and anywhere,consult and sort out materials by themselves,timely pay attention to the latest achievements of scientific research,expand students ' thinking and broaden their horizons.The application of modern teaching tools helps students to review and consolidate their knowledge,and cultivate students ' learning ability and thinking ability.The integrated mode of "teaching-learning-evaluation-help" changes the boredom in traditional teaching and the uniqueness of student evaluation,and the way that teachers evaluate students is more diversified;which helps to the personality development of students.The integrated teaching mode of "teaching-learningevaluation-help" will be more widely used in chemistry teaching.
