Research On The Design Strategy Of Junior Middle School Physics Teaching Question Chain Based On Scientific Thinking

The "Compulsory Education Physics Curriculum Standard(2011 Edition)" pointed out that cultivating students' good thinking habits plays a very important role in learning physics.Therefore,developing students' scientific thinking is the primary task of junior high school physics teaching.Through three years of teaching practice,it is found that teachers use a lot of questions in classroom teaching,but the effect is not good.In classroom teaching,the questions raised by teachers are more random,unclear,and poorly related,which leads to students' unanswered questions and difficulty in developing students' scientific thinking.According to related research,the question chain can cultivate students' material scientific thinking,to study how to effectively design the question chain to cultivate the physical science thinking of junior high school students.Through literature study,according to the needs of the times and teaching experience of curriculum reform,the current junior high school physics classroom teaching questions are untargeted and unrelated.Guided by the recent development area theory and constructivist learning theory,combined with the junior high school physics curriculum standards,The characteristics of junior high school physics,the thinking characteristics of junior high school students learning physics,and the design process and preliminary strategies of the question chain of junior high school physics teaching based on scientific thinking are proposed.Using the process and strategy of question chain design,three examples of junior high school physics teaching were designed,and teaching practice was carried out in X junior high school of Qin'an County,Gansu Province.Based on classroom observations,teacher and student interviews,the questions of junior high school physics teaching based on scientific thinking were tested.Preliminary strategy for chain design.Based on the practical effects of the preliminary design strategy and related teaching theories,the junior high school physics teaching question chain design strategy based on scientific thinking has been further improved: situation-question strategy,question-structure strategy,follow-up-focus strategy,thinking-construction strategy and method-analogy Strategy;put forward the corresponding application suggestions,and finally carried out reflection and prospects.The problem chain design strategy of junior high school physics teaching based on scientific thinking studied in this article has certain reference significance for cultivating junior high school students' physics scientific thinking.
