普通高中化学课程标准中强调要提高学生解决实际问题的能力，在问题解决的过程中引导学生经历发现、质疑、批判、反思的过程，从而实现知识的知识的自主建构是发展素养的重要途径之一。国内外专家都致力于研究研究问题解决教学的实践，项目式学习是当今国际流行的教育方式之一，但目前基于项目式学习理论的进行的课程开发成果仍然不够丰富。

本研究以项目式学习理论为基础设计开发了以“纳米金属材料”为主题的项目式校本课程的教学案例，并通过课程实施研究项目式课程的可行性及评价方法。

研究过程主要分为以下几个阶段：

第一阶段，查找梳理以“纳米金、纳米银”为主题的相关文献，归纳总结纳米金、纳米银在制备与应用方面的研究进展，运用项目式课程开发理论的标准规则完成“纳米金属材料”项目式校本课程的设计，包括查找真人真事，思路外显、将真人真事的研究思路转化为教学思路，课程框架的设计等。

第二阶段，实施项目式课程，对课程案例中任务一、任务二完成课程实施，通过调查问卷、课堂学生表现，访谈等方法分析学生问题解决思维、学科能力变化，研究项目式课程的实施效果。

研究结果表明，以“纳米金属材料”为主题的项目式校本课程具备一定的可行性，有益于构建学生解决问题的思维习惯，提升问题解决的能力并加深对化学的兴趣爱好。

The chemistry curriculum standard of ordinary senior high school emphasizes that it is necessary to improve students' ability to solve practical problems and guide students to go through the process of discovery, query, criticism and reflection in the process of problem solving, so as to realize the independent construction of knowledge is one of the important ways to develop literacy.

Experts at home and abroad are committed to studying the practice of problem-solving teaching. Project-based learning is one of the most popular international education methods, but the results of curriculum development based on project-based learning theory are still not rich enough.

Based on the project-based learning theory, this study designs and develops the teaching case of project-based school-based curriculum with the theme of "nano-metal materials", and studies the feasibility and evaluation methods of project-based curriculum through curriculum implementation.

The research process is mainly divided into the following stages:

In the first stage, we search and sort out the relevant literature with the theme of "nano-gold and nano-silver", summarize the research progress in the preparation and application of nano-gold and nano-silver, and use the standard rules of project-based curriculum development theory to complete the design of project-based school-based curriculum of "nano-metal materials", including finding real people, revealing ideas, transforming the research ideas of real people into teaching ideas, the design of curriculum framework and so on.

In the second stage, we implement the project-based curriculum, complete the implementation of task one and task two in the curriculum case, and analyze the changes of students' problem-solving thinking and subject ability through questionnaires, classroom student performance, interviews and other methods. to study the implementation effect of project-based curriculum.

The results show that the project-based school-based curriculum with the theme of "nano-metal materials" has a certain feasibility, which is beneficial to build students' thinking habits of problem-solving, improve their problem-solving ability and deepen their interest in chemistry.
