Molecular Laboratory Experiments in Chemistry

化学（12）这个项目解决了在化学入门级教学中的四个感知问题：需要支持以探究为导向的教学策略的课程材料;学生在连接宏观、微观和符号理解层面上的困难;需要基于计算机的教学材料，这些材料是简单的，动态的和互动的;需要识别和解决学生的误解。我们正在开发的教学材料，可以实施为一个综合的宏观（感官）/微观/符号探究为导向的实验室为基础的教学模式。具体而言，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。每个MoLE模拟是一个功能强大，交互式，动态的计算机模拟，并伴随着指导和开放式探究实验室活动。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入的理解。这些材料还允许教师和学生识别和解决学生可能对每个MoLE模拟中的目标概念存在的误解。几所不同的学院和大学正在测试和评估他们的学生在一些额外的教学设置，包括讲座，讲座补充，家庭作业，计算机实验室，作为团体或个人活动，并介绍或验证概念的材料。

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.
