A Study Of Teaching Strategies To Achieve The Core Literacy Goals Of The "Regulation Of Animal And Human Life Activities" In Senior High School

The high school biology curriculum shoulders the important mission of cultivating the core literacy of students in biology.The thesis uses modern educational teaching theory and modern teaching design concepts,with "core literacy ? core literacy in biology disciplines ? unit teaching design ? class teaching design" as the basic idea,taking the Human Education Edition of high school biology compulsory 3 "steady state and environment" Take the "Adjustment of Animal and Human Life Activities" as an example,fully tap the teaching materials that are conducive to the realization of core literacy,stand on the standpoint of students,start from expecting students to "learn what",and think retrospectively about "how students learn" around the whole unit conduct unit instructional design.Try to change teaching concepts,adjust teaching ideas,optimize teaching forms,and innovate teaching methods,integrate different "teaching strategies" based on "core literacy",and carry out the three-in-one teaching of "target,teaching,evaluation".When designing the teaching strategy for this unit,we should focus on the achievement of the core literacy goals of the overall biology of the unit,the teaching strategy of the unit and each class hour is designed systematically according to curriculum standards,unit content,student conditions,learning goals,teaching evaluation,which is conducive to the realization of the core literacy goals of the biology discipline.Based on the full use of multiple teaching strategies,focusing on the teaching characteristics of the unit content,the "four-step" concept teaching strategy,the inquiry teaching strategy of the history of biological sciences,and the STSE teaching strategy are emphasized.For example,most important concepts such as “neuroregulation”,“resting potential”,and “action potential” in this unit are relatively abstract,and mainly adopt the “four-step method” concept teaching strategy(the introduction of concepts,the construction of concepts,the consolidation of concepts,Concept deepening),and guide students to gradually understand important concepts,and form core literacy.The history of biological sciences such as "Discovery of Bioelectricity","Discovery of Secretin" and "Invention of Vaccine" are the best materials for cultivating the core literacy of biological disciplines,which contains the process of scientists exploring and discovering biological mysteries,mainly Adopting an inquiry teaching strategy in the history of biological sciences,focusing on cultivating students' scientific thinking and scientific inquiry literacy.The application of hormone drugs,the harm of drugs,organ transplantation,AIDS and other contents are closely related to science,technology,society and human health.They mainly adopt STSE teaching strategies and focus on training students' social responsibility literacy.The thesis uses "regulation through the nervous system","discovery of secretin" and "AIDS" as specific classes to show the teaching process of these three teaching strategies.After teaching design and practice,the following conclusions are drawn:(1)Under the premise of extensive use of multiple teaching strategies,this unit adopts the "fourstep" concept teaching strategy,the inquiry teaching strategy of the history of biological sciences,and the STSE teaching strategy to train students to the core of the biology subject according to the characteristics of the teaching content of each class.Literacy works well.(2)There are many teaching strategies conducive to the achievement of core literacy goals.At the level of instructional design,the combination of macroscopic unit instructional design and microscopic class instructional design is more conducive to the achievement of core literacy goals in biology.At the level of classroom teaching,the comprehensive use of multiple teaching strategies based on various teaching elements is more conducive to achieving the core literacy of the biological discipline.At the level of teaching evaluation,diversified teaching evaluation strategies can more effectively evaluate the achievement of core literacy goals.(3)Teachers should change teaching concepts,actively participate in the implementation of core literacy teaching,and reasonably choose teaching methods based on new curriculum standards and core literacy requirements,different teaching objects,different teaching environments,different teaching content,etc.method.The teaching strategy itself is not good or bad,the key is that teachers choose and use it properly in teaching.The use of various teaching strategies can be emphasized according to the personality of the teacher,and the combination of the development of the teaching sequence can form a unique combination,which cannot be rigidly applied.
