Research this base on, proceed from middle school student's thing classroom instruction practice, melt classroom instruction with the training of metacognition for an organic whole, metacognition ability to train student, study adaptability to raise student, settle solid foundation for the thing that students study and grow up healthy and sound all the life. Meanwhile, through study, analyze biology metacognition level, living beings study adaptability, relation of biological academic achievement, in order to promote its academic achievement to pursue a feasible route better.Under study for action, study, consult the literature, visit experts, ask the counterpart through theory study, have worked out the questionnaire of biology metacognition. The questionnaire is tried and repeated test in advance, the result shows: It have surveying characteristic of the better theory idea, good internal reliability, conception validity, distinguish degree, test-retest reliability, criterion related validity , etc. It can test middle school student biological metacognition, one a simple and convenient , effective tool.On the other hand, use method that literature study come, draw lessons from metacognition both at home and abroad train the scheme at first among experiment research, construct one go on the training of metacognition effective tactics that cognition train among biological discipline, experiment for one term that and is scheduled to last in experiment class. Among the experiment, permeate, discuss through thematic lecture, classroom route of exchanging etc. develops student's metacognition knowledge; Enrich the metacognition experience by teaching activity; Through measuring the card oneself, examination test and assess, analyze, question single reforming classroom instruction mode, little teacher, questionnaire result feedback, then guides the student to carry on the self- monitoring, the self- diagnosis, raises the metacognition monitoring skill. On the basis of studying in experiment, analyze the training of metacognition, study adaptability and concrete influence of academic achievement, construct biology metacognition and every key element of route models, construct biology metacognition, study adaptability, relation route model of academic achievement.The important conclusion of this research:1. Go on the training of metacognition among biological teaching, to different to study adaptability basic metacognition competence of classmate of level, all there is prominent improvement at studying the overall level of adaptability. There is improvement of prominent achievement in whole metacognition and every aspect. Among them at the metacognition aspect, study adaptability basic level higher group raise, not so good as medium-sized group, low grade result of group prominent.2. The training of metacognition can improve metacognition competence and academic achievement effectively. Training will improve more prominent to the achievement of the biological content which understands the level within short-term.3. Biology metacognition can promote students' study adaptability integral level to train. This kind of improvement cause more prominent result to study adaptability foundation medium-sized group and low grade group. The training of metacognition to attitude towards study, study technology raise prominent difference, but does not have much influence on academic environment and physical and mental health.4. Biology metacognition level, study adaptability present prominent medium-sized positive correlation extremely on academic achievement. Biology metacognition level is correlated with study adaptability level and exactly presenting the extremely strong one. (P<0.001)5. Biology metacognition, study adaptability, academic achievement between the three, the former two influence each other, the latter two influence each other too. Living beings study adaptability influence academic achievement, biology metacognition through study adaptability then influence the academic achievement indirectly. It is an intermediary variable that the living beings study adaptability. |
