Deep learning refers to the learning that on the basis of understanding knowledge,learners can critically learn new ideas and facts,integrate them into the original cognitive structure,connect among many ideas,transfer existing knowledge to new situations,make decisions and solve problems.As a form of efficient learning,how can deep learning take place effectively in the real teaching situation? This problem has become the focus of scholars’ research,and it is also an urgent problem to be solved in the research of in-depth learning.In foreign countries,problem-based learning is called "problem-based learning"(hereinafter referred to as PBL),which refers to a problem-oriented learning method.PBL teaching is a teaching model that puts students in complex and meaningful problem situations and improves students’ various abilities in the process of solving problems.This study mainly discusses two problems: 1 What kind of teaching strategy can promote students’ in-depth learning? 2.Whether PBL teaching can effectively promote students’ in-depth learning,and what is the effect of promotion? Therefore,based on the analysis of the relevant research on deep learning and PBL teaching at home and abroad,this study expounds the concept,characteristics and process of deep learning and PBL teaching in detail,puts forward the proposition of "PBL teaching promotes deep learning",and reveals the relationship between PBL teaching and deep learning from the theoretical level: the use of PBL teaching can promote students’ deep learning,This solves the problem of "how to promote students’ in-depth learning".However,can PBL teaching really effectively promote students’ in-depth learning in practical teaching? To answer this question,we need to contact the teaching practice,collect and analyze relevant data in the process of teaching for verification.Therefore,according to the teaching objectives in Chapter 4 material input and output of molecules and cells,a compulsory course for senior high school biology,combined with the psychological development characteristics of senior high school students and the previous research results,I constructed a PBL teaching process model to promote deep learning,and put forward its evaluation principles and methods;In the teaching practice,the questionnaire survey method,classroom observation method and test paper test method are used to collect the relevant data of students’ learning status and results.According to the data,the effect of PBL teaching on in-depth learning is analyzed.It is concluded that PBL mode has a significant effect in promoting the achievement of students’ knowledge objectives,the improvement of high-level abilities such as analyzing and solving problems,and the transformation of learning attitude and learning methods,It proves that it is feasible to use PBL teaching to promote deep learning. |
