The Application Research Of UbD Instructional Design Promoting Deep Learning In Biology Teaching In Junior High School

Biology Curriculum Standards for Compulsory Education(2022-year Edition)first proposed to cultivate students’ core biological literacy in the junior middle school stage.Deep learning is not only an important path for deepening curriculum reform and implementing core literacy in China,but also an important direction for talent cultivating.How to implement and achieve deep learning has become an urgent problem for front-line teachers.With the "big concept" as its core,and the "understanding" as its goal,and the end as its beginning,the method of Understanding by Design(UbD)is committed to guiding teachers to think about how to make students study in a more comprehensive and specific way from the "output end".It can not only have a high degree of internal synergy with the concept of deep learning,but also bring a new path for teaching design based on developing deep learning.Based on literature analysis,this paper examines research background and significance,summarizes research questions and contents,analyzes the research status,and clarifies the synergy of deep learning concept and UbD from theoretical perspective.Namely,both of them reflect unithood of teaching,highlight guidance of teachers,and focus on the transferability of knowledge.Thus,the feasibility of the research is determined.According to concrete ability representation of deep learning in three fields and six dimensions in junior high school biology,this study complies a questionnaire,and analyzes and summarizes status quo of biology deep learning ability of junior high school students.Based on the above theoretical research and investigation,the method model of Understanding by Design that promotes deep learning is constructed and interpreted.In order to verify the feasibility and effectiveness of this model in junior high school biology teaching,this paper revolves around the big idea,takes SKSX version of junior high school biology "Transport of Substances in Human Body" as the learning unit,designs unit learning objectives,conducts continuous unit learning assessment,unit learning experience and teaching,uses various classroom teaching strategies that promote deep learning in the experimental class,carries out practical application by class hours,and implements regular classroom teaching according to textbook arrangement in the control class.Lastly,the assessment evidence of continuous unit learning collected in unit teaching process is sorted out through educational qualitative research and other methods.The practical value of this model is assessed and the shortcomings in practice are reflected.The main conclusions of this research are as follows:Firstly,the method model of UbD for improving deep learning was constructed.Under the guidance of the big idea,teachers can organize relevant learning content into learning unit themes,clarify the literacy-oriented unit learning objectives,determine the continuous unit learning evaluation schemes,design the unit learning experience and teaching,and carry out classroom teaching practice.Secondly,the UbD model that promotes deep learning is feasible.This paper organizes the learning unit of "Transport of Substances in Human Body" and conducts practical application of UbD model that promotes deep learning.Through effective integration of unit content and reasonable allocation of class hours,teachers successfully conduct unit learning activities,guide students to demonstrate understanding ability via appropriate expressive tasks,and propel deep learning of students.Thirdly,UbD is favorable to trigger students’ deep learning.This study compares the evidence of various procedural and summative assessments of students in the experimental class in the unit learning process with five characteristics of deep learning proposed by Professor Guo Hua,and finds that students have made progress in five aspects of deep learning:"association and structure","activity and experience","essence and variation","transfer and application",and "value and evaluation".Therefore,the method model of UbD for improving deep learning can be effective in the field of junior high school biology teaching.
