计算机辅助物理实验教学的几点思考

探讨了物理实验教学引入智能化仪器的必要性和意义，指出引入计算机辅助教学必须对传统的实验教学内容和方法重新设计，同时软件的设计应给学生留有接口的余地。     

Fractional commensurate, composition, and adding schemes: Learning trajectories of Jason and Laura: Grade 5

A case study of two 5th-Grade children, Jason and Laura, is presented who participated in the teaching experiment, Children’s Construction of the Rational Numbers of Arithmetic. The case study begins on the 29th of November of their 5th-Grade in school and ends on the 5th of April of the same school year. Two basic problems were of interest in the case study. The first was to provide an analysis of the concepts and operations that are involved in the construction of three fractional schemes: a commensurate fractional scheme, a fractional composition scheme, and a fractional adding scheme. The second was to provide an analysis of the contribution of interactive mathematical activity in the construction of these schemes. The phrase, “commensurate factional scheme” refers to the concepts and operations that are involved in transforming a given fraction into another fraction that are both measures of an identical quantity. Likewise, “fractional composition scheme” refers to the concepts and operations that are involved in finding how much, say, 1/3 of 1/4 of a quantity is of the whole quantity, and “fractional adding scheme” refers to the concepts and operations involved in finding how much, say, 1/3 of a quantity joined to 1/4 of a quantity is of the whole quantity. Critical protocols were abstracted from the teaching episodes with the two children that illustrate what is meant by the schemes, changes in the children’s concepts and operations, and the interactive mathematical activity that was involved. The body of the case study consists of an on-going analysis of the children’s interactive mathematical activity and changes in that activity. The last section of the case study consists of an analysis of the constitutive aspects of the children’s constructive activity, including the role of social interaction and nonverbal interactions of the children with each other and with the computer software we used in teaching the children.     

仪器分析测试技术信息化教学探索与实践

针对高职学生的特点，以仪器分析测试技术课程实训教学为例，按照课前布置学习任务，学生翻转课堂学习，"教、学、做"一体化课堂教学，课后复习巩固的形式，开展信息化教学的探索与实践，并对信息化教学的效果和存在的问题进行了分析。通过信息化教学改革，仪器分析测试技术课程突破了传统教学时空的限制，激发了学生学习的兴趣，构建了"学生主体、教师主导"的教学新模式，提高了课堂教学效果，对推动高职课堂信息化教学的改革具有一定的借鉴意义。

Use of Spectroscopic Representations in Student‐Generated Atomic Models

Abstract

The goal of this paper is to illustrate college students' levels of sophistication of their spectroscopic representations (SRs). For example, a photon is drawn as a wavy line, which might be used to enhance their atomic models (AMs). Study 1 was a quantitative study in which 70 students, enrolled in first semester general chemistry, drew or described their own model of the atom. Despite the fact that they had just completed a unit on atomic structure, only 30.6% of these students were classified as having a good understanding of the Bohr AM. Most of these students, 93.8%, incorporated SRs into their models. Conversely, only 41.2% of those who had a moderate AM understanding and only 5% of those with a poor AM understanding used SR in their AMs. Study 2 was a qualitative study in which 10 volunteers, enrolled in the same course but during a different semester, interacted with a multimedia instructional package and with a tutor. Interviews with two students were selected for in‐depth analyses. Each one enhanced their own AM by adding dynamic SR to their original AMs.

《聚合物基复合材料》课程中的问题式学习

问题式教学是以增强问题意识和发现、分析和解决问题的能力为目的的教学模式。问题式教学对改变传统教学方式,培养学生发现、分析和解决问题的能力,形成创造力具有重要意义。吉尔福特的智力结构理论把智力分解成120个智力因子,有助于理解思维的基本属性。在聚合物基复合材料课程中把问题式教学和智力结构理论结合起来,针对不同的智力因子有目的性地设置问题,可以培养学生科学的思维方式,锻炼归纳、分析、联想等思维能力,提高学习和科研水平。
