Research On The Effectiveness Of Task-driven Teaching Method In Junior High School Science Experiment

As a new teaching model based on the theory of constructivism,task-driven teaching is compatible with the concept of independent inquiry in scientific experiment class,and connects the activities of teachers and students with task as the carrier.It is important to put forward the corresponding rationalization strategy and test its effectiveness in practice.Through literature review and analysis,classroom record observation and in-depth interviews with teachers,this study investigated the implementation status of task-driven teaching method in experimental classrooms.The problems mainly focusing on task setting,teacher teaching and student activities.Taking into consideration,this paper combines the existing basic framework of task-driven teaching method to distinguish "traditional assigned tasks" from "task-driven teaching" and makes strategy improvement and effectiveness test.The first is to extract error-prone points,add task chains,and strengthen understanding through trial-and-error teaching;Secondly,it focuses on the elaboration of instruction language and the addition of problem chain to promote effective interaction in class;The third task list is designed to clarify the group responsibility system,enrich the evaluation system,and improve students' participation and ability.On the basis of the design of teaching case and carry on empirical research,correct judgment during the course of the research topic of draw gear and corresponding examination site small statistics,comprehensive volume(experimental group)shows A class teaching effect is better than that of class B(control group)to some extent.The effects of individual scores and class total scores were more significant,which is embodied in the fill in the blanks with the probe into two parts.At the same time,it is found that the setting of teaching schedule and task difficulty is an important factor for the subsequent improvement,hoping to provide reference Suggestions for teachers to effectively implement the task-driven teaching method in the experimental class.
