项目摘要
This project is creating new active-learning curricular materials, labeled active learningpackets (ALPs), for the topics of stoichiometry, acids and bases, thermochemistry, kinetics, gas-phase equilibria, acid-base equilibria, and electrochemistry. The motivation for the creation of the ALPs is research on student learning that suggests instruction utilizing only lecture, recitation, and laboratory experiments produces only small increases in the understanding of fundamental concepts in chemistry. The ALPs are incorporating techniques, including McDermott's guided inquiry framework, visualization and inquiry simulations, and writing-to-learn strategies that research has shown will improve conceptual learning. The active learning materials are being designed to both elicit common student difficulties regarding the topics under study and to lead students to confront these difficulties head-on with a tightly focused and strategically sequenced series of exploratory activities, questions, and exercises. For each topic, three or four discrepant events, phenomena that lead to an unexpected outcome and often produce conceptual conflict, are included. A discrepant event sufficiently surprising or contrary to an expected or predicted outcome captures the attention of the student and encourages rethinking. An integral feature of the proposed learning activity exercises is the requirement that students explain their reasoning process with written statements. In the course of working through these inquiry activities, students are being guided to resolve their difficulties and confusion and to attain a firm grasp of the targeted concepts. The activities consist of a tightly linked set of (1) brief textual expositions in highly "interactive" format, (2) concept-oriented questions for use with classroom communication systems in large classes, (3) a structured series of questions that lead students to elicit and then resolve conceptual difficulties, and (4) exploratory visualization and inquiry simulations and hands-on activities and writing-to-learn exercises to strengthen understanding. The activities are emphasizing qualitative understanding, reasoning, and mastery of fundamental concepts. They are encouraging students to develop multiple representations of concepts in pictorial, diagrammatic, and graphical formats and to relate these representations to symbolic and macroscopic representations. The effectiveness of the ALPs is being rigorously assessed by continual in-class use and redesign, in conjunction with evaluation of student learning gains.
该项目正在为化学计量学、酸和碱、热化学、动力学、气相平衡、酸碱平衡和电化学等主题创建新的主动学习课程材料,标记为主动学习包(ALP)。创建ALP的动机是对学生学习的研究,该研究表明,仅利用讲座,背诵和实验室实验的教学只会对化学基本概念的理解产生很小的增加。ALP结合了一些技术,包括麦克德莫特的引导式探究框架、可视化和探究模拟,以及研究表明将改善概念学习的写作学习策略。主动学习材料的目的是既引出共同的学生的困难,关于正在研究的主题,并带领学生面对这些困难的头部与一个紧密的重点和战略顺序的探索性活动,问题和练习。对于每个主题,三个或四个差异事件,导致意想不到的结果,往往产生概念冲突的现象,包括在内。一个与预期或预测结果完全相反或令人惊讶的不一致事件会吸引学生的注意力,并鼓励他们反思。建议的学习活动练习的一个不可或缺的特点是要求学生用书面陈述解释他们的推理过程。在开展这些探究活动的过程中,引导学生解决困难和困惑,并牢牢掌握目标概念。这些活动包括一系列紧密联系的:(1)高度“互动”格式的简短文本阐述,(2)用于大班课堂交流系统的概念导向问题,(3)引导学生引出并解决概念困难的一系列结构化问题,以及(4)探索性可视化和探究模拟以及实践活动和写作学习练习,以加强理解。这些活动强调定性理解,推理和掌握基本概念。他们鼓励学生发展概念的多种表现形式,如图画、图表和图形,并将这些表现形式与符号和宏观表现形式联系起来。通过课堂上的持续使用和重新设计,以及对学生学习成果的评估,对ALP的有效性进行了严格的评估。
