Chemistry (12)This project addresses four perceived problems in instruction at the introductory level in Chemistry: a need for curriculum materials that will support an inquiry oriented instructional strategy; the difficulty students have linking macroscopic, microscopic and symbolic levels of understanding; a need for computer-based instructional materials that are simple, dynamic and interactive; a need to identify and address students' misconceptions. We are developing instructional materials that can be implemented as an integrated macroscopic (sensory)/microscopic/symbolic inquiry-oriented laboratory based instructional model. Specifically, we are developing eight Molecular Level Experiment (MoLE) Simulations: Gas Laws, Gas Phase Equilibrium, Kinetics, Atomic Structure and Periodicity, Acid-Base Chemistry, Calorimetry, Electrochemistry and Molecular and Solid State Structure. Each MoLE Simulation is a powerful, interactive, dynamic computer simulation, and is accompanied by a guided and open-inquiry laboratory activity. The materials help students link the macroscopic, microscopic and symbolic worlds together and allow them to develop a deeper understanding of these chemical phenomena. The materials also allow faculty and students to identify and address misconceptions students might have concerning the target concepts in each MoLE Simulation. Several different colleges and universities are testing and evaluating the proposed materials with their students under a number of additional instructional settings, including lecture, lecture supplements, homework assignment, computer laboratory, as either group or individual activities, and to introduce or verify concepts.

化学(12)这个项目解决了化学入门阶段教学中的四个公认问题：需要支持以探究为导向的教学策略的课程材料；学生难以将宏观、微观和符号层面的理解联系起来；需要简单、动态和互动的基于计算机的教学材料；需要识别和解决学生的错误概念。我们正在开发教学材料，可以作为一个以宏观(感官)/微观/符号研究性实验室为基础的综合教学模式来实施。具体地说，我们正在开发八个分子水平实验(Mole)模拟：气体定律、气相平衡、动力学、原子结构和周期性、酸碱化学、量热法、电化学以及分子和固态结构。每一次摩尔模拟都是一个强大的、交互的、动态的计算机模拟，并伴随着一个有指导的、开放式的实验室活动。这些材料帮助学生将宏观、微观和符号世界联系在一起，并让他们对这些化学现象有更深的理解。这些材料还允许教师和学生识别和解决学生在每个鼹鼠模拟中可能存在的关于目标概念的误解。几所不同的学院和大学正在一些额外的教学环境下与学生一起测试和评估拟议的材料，包括讲座、课堂补充材料、家庭作业、计算机实验室，作为小组或个人活动，并介绍或验证概念。
