Abstract

It is imperative that a profound transformation be carried out in the traditional way in which we teach science subjects, so it is necessary that the role of student change from being a mere recipient of information to being the main player in the construction of his knowledge. One of the strategies to achieve this is to make use of ICT, within which are educational simulators, as a support resource to facilitate the teaching-learning processes taught in the classroom. The didactic strategy developed in this work was carried out with the PhET (https://phet.colorado.edu) simulator was used to improve the teaching of the Law of Conservation of the Matter and its relationship with chemical reactions. To evaluate the learning acquired by students, the Hake factor was determined. In terms of the implementation of this didactic strategy, students demonstrated greater recognition, understanding, and appropriation of the knowledge gained about the importance of this law in chemical reactions. This teaching strategy is useful for higher middle-level schools that do not have a school science lab.
高中物质守恒定律与化学反应在线模拟教学
我们必须对传统的科学教学方式进行深刻的变革,因此学生的角色必须从单纯的信息接受者转变为构建知识的主要参与者。实现这一目标的战略之一是利用信息和通信技术,其中包括教育模拟器,作为一种支助资源,促进课堂上讲授的教学过程。在这项工作中开发的教学策略是通过PhET (https://phet.colorado.edu)模拟器进行的,用于改进物质守恒定律及其与化学反应关系的教学。为了评价学生获得的学习,我们确定了哈克因子。就这一教学策略的实施而言,学生表现出对化学反应中这一定律重要性的认识、理解和运用。这种教学策略对没有学校科学实验室的高等中等学校很有用。
