基于计算机探究性建模的高中化学“反应速率”教学设计

Teaching Design of “Chemical Reaction Rate” in Senior High School Based on Computer Exploratory Modeling

模型和建模是化学核心素养的重要组成部分。计算机辅助建模具有可视化性,能创设探究性学习环境,在教师引导学生构建模型和学习概念中扮演着重要角色。基于计算机辅助建模的优势,开展注重学生参与度、由学生自主建模的探究性教学。以“化学反应速率”为例,选择计算机建模工具SageModeler作为辅助技术,围绕心智模型的建立、评价、发展和优化,旨在通过建模教学提高学生对模型本质的理解,发展学生建模的观念和能力,形成对化学反应速率的清晰认识。

Model and modeling are important components of chemistry core literacy. Computer modeling plays an important role in guiding students to build models and learn knowledge, because of the benefits on visualizing abstract phenomena and creating an inquiry-based learning environment. Based on the advantages of computer modeling, this paper developed an inquiry-based teaching design by using a computer modeling tool, SageModeler to teach chemical reaction rate. This paper aims to provide an insight of how to use a computer modeling tool to build, evaluate, develop, and optimize students’ mental models in a chemistry classroom. Furthermore, teachers and researchers may implement this exploratory modeling instruction in the real classroom to increase students’ comprehension of the nature of models, develop modeling competency, and generating a clear understanding of chemical reaction rates.
