高中生物“研究性课题”指导设计及案例分析

Design and Case Analysis of "the Topic for Study or Discussion"in Senior Biology

“研究性课题”是编排在现行高中生物教材中的一类实施研究性学习的课程载体.主要介绍了研究性课题的内涵及特征,阐述了课题的指导策略和设计要素,选取了“培养学生搜集和分析资料能力”这一专题(采用1个典型案例),进行了研究性课题案例的指导设计、教学实践以及分析.由此可得出结论:生物学是与生产和现实生活密切联系的学科,非常适合开展研究性课题;一个自由、和谐、宽松和平等的教学氛围是激发学生创造性思维所必需的;研究性课题有极大的开放性,因此教师要把握好开放的“度”;教师应注重启发学生拓宽搜集资料的渠道,教给他们处理资料信息的方法.

'The topic for study or discussion'(TSD) arranged in the present textbook of senior biology is a kind of course carrier by which inquiry study can be carried out.The meaning and identity of TSD are introduced,guide strategy and design elements are elaborated.The special topic,namely 'fostering students'ability of gathering and analyzing information'is selected for making a design and analysis of case of TSD.And then the teaching practice are carried out by the case designed well.It could be concluded that biology is a subject closely cont acted with real production and life,therefore it is very suited to put TSD into effect by biology;a free,harmonious,relaxed and equal teaching atmosphere is essential for inspiring students to the creative thinking;TSD is very open,therefore teachers should have a good grasp of the degree of openness;directors should enlighten students on opening up the channel to collect information and teach them the methods of dealing with information and message.
