Research On The Teaching Mode Of STEM Class Based On Project-based Learning

STEM education is a comprehensive teaching of science,technology,engineering and math,and plays an important role in the cultivation of innovative talents.Project-based learning provides students with a real learning environment that is connected to reality and provides ideas for the design of STEM teaching models.The STEM lesson teaching model based on project-based learning is an important way to cultivate talents.At present,the research of STEM lesson example teaching mode mainly focuses on the combination with related subjects and certain theories,relatively speaking,it lacks the integration with teaching practice,and has not yet formed a complete set of STEM lesson example teaching mode based on project-based learning..Therefore,this research attempts to construct a STEM lesson teaching model based on project-based learning.First,through literature analysis and visits to relevant schools that carry out STEM courses,a set of project-based learning STEM lesson teaching models for primary and secondary schools are designed based on STEM core literacy.This model takes teachers and students as the two main bodies to prepare for learning,learning process,and Learning evaluation is divided into three stages,with six small steps including context,tasks,resources,process,presentation and evaluation,which run through contextual learning,inquiry learning and evaluation learning.Secondly,iterative teaching experiments are carried out in elementary schools with action research to guide the design of lesson examples,using multiple,diversified,and multi-dimensional evaluation methods to measure teaching effects from the dimensions of STEM knowledge,STEM value,and STEM attitude.The survey of the completion of teaching objectives and the satisfaction of teaching methods in the first round of experiments found that this model can improve students’ core STEM literacy to a certain extent,but there are still some problems in student product production and teaching evaluation.After the model was modified,the second round of experimental data showed that the model had a positive impact on students’ STEM literacy,and it corrected and improved the problems that appeared in the first round of experiments.Therefore,iterative experimental research proves that the STEM lesson teaching model based on project-based learning can develop and improve students’ STEM literacy to a certain extent,and cultivate innovative talents with interdisciplinary literacy.In the future,we hope to apply different STEM lesson examples to further optimize and improve the STEM teaching mode,in order to provide new ideas for the construction of STEM...
