Study On The Effective Classroom Teaching Strategy Of Junior Middle School Chemistry Based On Learning Science

Learning science has developed from the interdisciplinary field of study in the past 30 years,involving the brain science,education psychology,cognitive science and many research fields such as information technology.It is mainly about all areas of knowledge and more in-depth comprehensive study on how people learn widely in recent years.However,there is few systemic research about junior middle school chemistry and the application of the theory of learning science in middle school teaching research has not done yet.Therefore,the author carries on the research and exploration of the effective classroom teaching strategy based on the learning science theory and combined with the junior high school chemistry teaching practice.Through the questionnaire survey and teacher interview,more Information about the current condition of junior middle school students' chemistry learning is gathered.The current class is mainly taught by the teacher for a whole period,whether it is new class or exercise class.Students' activities in class are very few,which leads to students' easy fatigue and sometimes inattention.The teacher speaks continuously and the students' questions can't be solved in time,which causes the awful effect;What's more,it also takes a long time for the students to finish the homework after class.If the questions are not sorted and comprehended,mistakes will be made again,which means that students' learning efficiency in chemistry is not high enough.Combined with the cognitive load theory,skinner's program teaching method and other relevant theories on the study of neuroscience and psychology in learning science,the effective classroom teaching strategy of junior high school chemistry is formed by using the school digital teaching platform.It includes: preparing strategy class strategy and strategy effective lessons after class.The mode is divided into three,including personal practice,group preparation and collective lesson preparation from the platform.The strategies of effective classroom teaching include: stimulating students interest in learning by led-in interestingly,for example,knowledge is contextualized in daily life,making knowledge abstract to concrete.Also,Clever memory method reduces students' memory burden;Digital platform “big data” leads teaching;Output type,fully mobilize students each other to solve the problem efficiently strategy which make use of digital platform layered homework after class the function of the automatic generation of electronic wrong topic one-to-one tutoring for targeted planning effectively,is the precondition of efficient classroom,efficient strategy can make the classroom get twice the result with half the effort,in class after class review,effectively for the consolidation of knowledge to lay a good foundation for efficient preparation in class after class strategy of the trinity,power efficient teaching and learningThrough applying effective strategies to the practice of teaching,experimental classes use efficient preparation classes and after-school tutoring strategy,and the comparative classes are still use the traditional teaching strategies.In the half a year's experiment contrast research,through the analysis of the results of large-scale test,and through the questionnaire survey to understand students' chemistry learning situation,finds that the experimental classes of students are better than that in comparative classes both in terms of chemical achievement and interest in chemistry study habits.Experimental teachers' abilities are also improved,reflecting the effectiveness of the highly effective classroom teaching strategiesEfficient teaching strategy is not only reflected in the achievement of teaching objects and the improvement of students' performance,but also reflected in the cultivation of students' interest and habits and the potential to stimulate the improvement of discipline quality...
