Research On The Unit Integrated Teaching Design Of High School Chemistry Based On In-Depth Teaching

The rapid development of the new era has promoted the current educational reform,and society needs innovative talents with deep learning capabilities,and "knowledge workers" who stay in shallow learning will eventually be eliminated.The Standardfor General High School Chemistry Curriculum(2017 Edition,2020 Revision)points out that the classroom should be based on the principle of "adhering to the requirements of the times" to transform the training mode of talents;Theme-led to achieve the structuring and contextualization of course content,thereby promoting students’ in-depth understanding of knowledge and improving students’ deep-learning ability.As the guide of students’ development,teachers should point out the direction and path for students’ deep-learning based on in-depth teaching theory.At the same time,the unit integrated teaching can realize the structure and contextualization of knowledge,which can provide an effective implementation way for in-depth teaching.Therefore,taking "nitrogen and its compounds" as an example,the overall teaching of units based on in-depth teaching is carried out at the high school level to improve students’ deep learning ability.The specific contents are as follows:(1)This paper reviews the research status of deep-learning and in-depth teaching,visually analyzes the literature of the unit integrated teaching,clarifies the development context of deep-learning,in-depth teaching and unit overall teaching,and determines the research theme.Guided by constructivist learning theory,Bloom’s cognitive goal taxonomy and learning transfer theory,questionnaires for students and teachers are designed to understand students’ deep-learning ability and unit teaching status.(2)Six key processes of the unit integrated teaching design based on in-depth teaching were constructed:(1)The learning theme was established;(2)Formulate unit teaching objectives;(3)Reconstruct knowledge content;(4)Design unit theme activities;(5)Plan the overall teaching process of the unit;(6)Formulate unit teaching evaluation plans.(3)Taking the unit of "nitrogen and its compounds" as an example,the unit content was analyzed and reorganized in combination with the textbooks published by Shandong Science and Technology Press,Jiangsu Education Press and Shanghai Science and Technology Press.It was realized that the secondary development of the teaching materials under the unit content.On the basis of improving the relevant teaching design,the teaching practice was carried out,and the 5th and 8th classes of the first grade of a high school in J Province were selected as the research objects for practical comparison.(4)Unit test questions were designed based on the two dimensions:learning level and cognitive level,and after the implementation of teaching intervention,the experimental class and the control class were tested.The test results show that the students in the experimental class have a deeper understanding of knowledge,and the experimental class is significantly better than the control class in terms of academic performance and deep-learning ability.The results show that the unit integrated teaching based on in-depth teaching can significantly improve students’ deep-learning ability,promote students’ development,and provide an effective method for cultivating students into adaptive and innovative talents in the 21st century.Teachers and scholars can selectively apply the process paradigm and teaching design proposed in this paper to practice according to the actual situation.
