在常规课堂教学中实施项目式学习———以化学教学为例

Exploring Project-Based Learning in Regular Classroom Teaching: A Case Study of Chemistry Teaching

在不同类型学校、不同年级的中学化学课堂中实施项目式学习，主要分为确立项目和规划项目两个步骤，确立项目要基于课程标准、教学内容和学生经验。规划项目包括三个阶段：拆解项目，确立项目的基本问题、单元问题及内容问题；规划课时及其安排；系统审视、优化设计。在常规课堂教学中实施项目式学习的关键问题和解决对策如下。（１）让学生亲历问题解决过程；（２）注重过程技能的培训和指导；（３）时间紧张，课上课下任务要统筹安排；（４）进行系统性、针对性评价的设计与实施；（５）突发事件的应对与处理；（６）教师需要养成实施项目式学习的教学观念和教学行为。

Project-based learning is a approach to learning that planning and solving project tasks in co- operation group， applying more in comprehensive practical activities and research study in our country， li--tle application and research in a conventional classroom Teaching. Designing and implementing project-based learning in high school chemistry class in different types of schools and different grades is mainly di- vided into two steps， establishing project and planning project. Establishing the project is based on curriculum standards，teaching content and student experience. Planning project includes three phases: dismant- ling project and establishing basic issues，untt issues and content issues； planning class hour and arrangement ；reviewing systematically and optimizing the design. The key ssues and solutions to implement project-based learning in the regular classroom are as follows: (1) allow students to experience the problem- solving process； (2) focus on process skills’ training and guidance； (3) time constraints， co-ordinate arrangements in and out class； (4) designing and implementation of systematic and targeted evaluation； (5) deal with handling emergencies； (6) teachers need to develop teaching concepts and teaching behavior of the implementation in project-based learning.
