浅谈《化工基础》课堂教学导入设计

教学导入是课堂教学中的一个重要环节,是课堂教学内容的前奏,如同一出戏的“序幕”。课堂教学导入的合理设计可为一堂课的教学效果创造一个良好开端。根据《化工基础》课程的特点,本文笔者主要介绍了几种该课程教学中常用的导入方法。     

大学化学反应级数测定实验的研究

本文通过Fe^3＋反应级数测定的实验．介绍大学化学实验教学方法的一种思路：在课前安排学生预习并思考一些问题,实验过程中以学生自己动手为主．教师适当加以引导．最后对每组的情况进行点评．此方法可调动学生的积极性,培养学生发现问题和分析解决问题的能力．激发学生曲创新音犋     

化学分析技术和仪器分析技术课程改革初探

笔者根据化学分析技术和仪器分析技术课程特点,结合多年的教学经验,对化学分析技术和仪器分析技术教学体系进行初步改革,这种改革在初步实践中取得了明显效果。     

药学类专业“化工原理”课程教学的探讨

药学类专业的化工原理课程学时少,学生的知识体系有别于化工专业。在教学内容的选择上,应侧重和制药过程相关的内容;采用多媒体教学能使学生直观了解化工单元操作的情况,提高学生学习的兴趣和主动性;加强任课教师在制药领域的知识能够更好地引导学生应用基础理论解决实际制药过程中的问题。     

体验式教学及其在高中化学教学中的重要性

在高中化学教育中实施体验式教学是新课改实施的重要举措,以学生为主体,师生互助合作,共同创造激发学生兴趣、提高学生积极性的课堂情境和教学情境,共同推进化学教育迈向新的台阶。     

高中化学问题解决中的表征与策略研究

高中化学问题的解决需要依赖问题的表征和策略.如果对问题的表征正确处理,那么在解决问题时难度就会降低.对高中化学问题解决中的表征和策略研究有利于指导化学教师开展教学,对学生的学习也有积极的指导意义.     

Aspen Plus在化工学习中的应用

在化工学习中,应用Aspen Plus对化工生产中的典型工艺———苯加氢合成环己烷系统进行模拟,结果表明,Aspen Plus不仅可以简化复杂的化工过程,而且可以提高学生学习的效率和质量,增强工程意识,有利于理论和实践的结合。     

A jigsaw cooperative learning application in elementary science and technology lessons: physical and chemical changes

Cooperative learning is an active learning approach in which students work together in small groups to complete an assigned task. Students commonly find the subject of ‘physical and chemical changes’ difficult and abstract, and thus they generally have many misconceptions about it.

Purpose

This study aimed to investigate the effects of jigsaw cooperative learning activities developed by the researchers on sixth grade students’ understanding of physical and chemical changes.

Sample

Participants in the study were 61 sixth grade students in a public elementary school in Izmir, Turkey.

Design and methods

A pre-test and post-test experimental design with a control group was used, and students were randomly assigned to the experimental and control groups. Instruction of the subject was conducted via jigsaw cooperative learning in the experimental group and via teacher-centered instruction in the control group. During the jigsaw process, experimental group students studied the subjects of changes of state, changes in shape and molecular solubility from physical changes, and acid–base reactions, combustion reactions and changes depending on heating from chemical changes in their jigsaw groups.

Results

The concept test results showed that jigsaw cooperative learning instruction yielded significantly better acquisition of scientific concepts related to physical and chemical changes, compared to traditional learning. Students in the experimental group had a lower proportion of misconceptions than those in the control group, and some misconceptions in the control group were identified for the first time in this study.

Conclusions

Jigsaw cooperative learning is an effective teaching technique for challenging sixth grade students’ misconceptions in the context of physical and chemical changes, and enhancing their motivation, learning achievements, self-confidence and willingness in the science and technology lesson. This technique could be applied to other chemistry subjects and other grade levels.     

Implementation of a cooperative methodology to develop organic chemical engineering skills

The objective of this work is to investigate how most of the competences required by engineering students may be developed through an active methodology based on cooperative learning/evaluation. Cooperative learning was employed by the University of Huelva's third-year engineering students. The teaching methodology pretends to create some of the most relevant engineering skills required nowadays such as the ability to cooperate finding appropriate information; the ability to solve problems through critical and creative thinking; and the ability to make decisions and to communicate effectively. The statistical study carried out supports the hypothesis that comprehensive and well-defined protocols in the development of the subject, the rubric and cooperative evaluation allow students to acquire a successful learning.
