Research On Elementary School Science Project-based Teaching Design Based On APT Theory

The new era has given information education a new mission.In order to strengthen China’s educational modernization,the Ministry of education has formulated the action plan for educational informatization 2.0,which takes informatization as the endogenous force of contemporary educational transformation,so as to promote the development of educational ideas,educational models and the reconstruction of educational system,so as to cultivate talents suitable for the social development of the 21 st century,Realize the power of education.Primary school science in the new era is a basic,practical and comprehensive course.It pays attention to the cultivation of students’ scientific literacy.It aims to improve students’ ability to use various scientific knowledge to deal with practical problems,so that students can maintain their enthusiasm for scientific learning and lay a solid foundation for lifelong development,PBL(problem-based learning)teaching method is completely consistent with the training objectives of contemporary science.It is problem-oriented and solves problems in the real situation through independent and cooperative exploration,so as to improve students’ ability to solve problems and enhance their interest in classroom learning.In this thesis,the author tries to combine APT theory integrating teaching evaluation,pedagogy and technology with PBL teaching method,in order to optimize science information teaching mode and improve students’ problem-solving ability and learning interest in science classroom.This thesis attempts to solve the following four problems:(1)how to better integrate APT theory with project-based teaching?(2)How to apply the project-based teaching model based on APT theory to the unit teaching of "electric ability" ?(3)how to carry out evaluation in the process of teaching implementation?(4)what is the effect of project-based teaching based on APT theory?In view of the above problems,this thesis uses the methods of literature research,questionnaire survey and experimental research to carry out the relevant research in that stage:firstly,by reading the relevant literature of APT theory and project-based teaching,the APT theoretical model is integrated with project-based teaching,and the project-based teaching model based on apt theory is constructed;Then the teaching model is used to carry out the teaching design,evaluation design and teaching practice for the unit of "power of electricity";Finally,by analyzing the pre-test and post-test questionnaire data,paper and pen test data after teaching,and combined with the timely interview results between students and teachers,we draw the following conclusions:(1)project-based teaching based on APT theory is feasible in the teaching of Science in primary school.(2)To a certain extent,it has improved students’ interest and motivation in classroom learning.Compared with the pre-test,the number of people who are very interested in the current science classroom has increased by 20%,the number of people who are not interested has decreased from 8.6% to 2.9%;and the number of people who want to learn scientific knowledge has increased from 22.8% to 31.4%;because they take the exam,The proportion of people who were praised and required by school teachers decreased by 14.3%,2.9% and 11.4%respectively.(3)The teaching model has a positive impact on students’ problem-solving ability.Students’ ability in three aspects: the attitude towards problems,the way to deal with problems and the quality of problem-solving has been significantly improved.(4)The teaching model has improved the students’ academic performance to a certain extent.In the paper and pen test data of teaching practice,there is a significant difference between the experimental group and the control group,and the experimental composition performance is slightly higher than that of the control group.The project-based teaching based on APT theory improves students’ interest and motivation in science learning,has a positive impact on students’ problem-solving ability,deepens the integration of informatization and primary school science classroom teaching,and provides some reference value for the teaching of other courses.
