基于弗雷泽建构主义课堂环境理论构架,采用量化研究与质化研究相结合的方法,编制了中学化学建构主义课堂环境量表(SCCLES),并运用SCCLES测量了625名中学生对建构主义化学课堂环境的感知状况。研究结果表明:SCCLES具有良好的效度和信度,是较为经济、实用、有效的过程性课堂评价工具;中学化学课堂环境存在“传统型”“中间型”和“建构型”等3种类型;不同课堂环境类型的学生在“学生声音”“个人相关”“合作”“任务取向”等维度的感知存在显著差异。 相似文献

With its tailored learning content, flexible learning environment and directed teacher guidance, the flipped classroom in "nutrition chemistry" has effectively solved the problems of students' specialty, large number and limited time in the course of elective course. The teaching mode based on the cultivation of students' ability and the core of improving scientific literacy was constructed. 相似文献

The COVID-19 broke out on a large scale, and online teaching became the first choice for teachers. Avoiding network congestion and ensuring learning effects are the dilemmas faced by online teaching. With the help of the UOOC platform and the Tencent Classroom, taking the "Polymer Structure and Performance" course as a sample, we suggested a new "online asynchronous teaching" model. Among them, the SPOC course is convenient for students to manage their learning time; "Chapter Quiz" and "Student-to-Student Mutual Evaluation" are helpful for students to obtain multi-angle feedback; project tasks are focused on case analysis so that students carry out inquiry-based learning. Overall, the "online asynchronous teaching" model breaks the time and space restrictions on teaching and learning, guarantees the quality of teaching during the epidemic, and lays the foundation for creating a "golden class". 相似文献

This paper explored "the classroom debates" in "nutrition chemistry" course. After evaluating the students' expectation in participating activities, the participating degree and their gains from the activity, it was found that the performance and gains from the "classroom debate" were influenced by provincial locations, genders and majors. The results showed that "the classroom debates" need to coordinate the students' speculative thinking ability, creative thinking, team playing, medical ethics and professional education as a whole. This would help the students to form a way of critical thinking as well as the right outlook on life and value system. 相似文献

In the article, we presented an instructional design of "Particle in One-Dimensional Box Theory" and "HMO Theory" application based on flipped classroom teaching. The students are instructed to use both "Particle in One-Dimensional Box Theory" and "HMO Theory" to solve the electronic structure of olefins and enhance their understanding of quantum mechanics theory via comparison of "Particle in One-Dimensional Box Theory" and "HMO Theory". 相似文献
