摘要

研究的目的是在基本化学概念的基础上对环境污染问题进行专家验证。研究的类型是设计和开发,涉及三个专家作为验证者。数据处理采用SPSS ver。通过肯德尔测试。渐近线的值。在与国家课程和可持续发展目标指标的兼容性、与创造性思维指标的兼容性以及语言使用的清晰度方面,学习前问题是有效的。学习前问题分为十个指标。他们大多要求学生描述温室气体、重金属、固体或液体纳米塑料是如何破坏环境的。学生们解释并写下这些过程的化学表征,即宏观的、亚微观的和象征性的。学习前的问题是有效的,因为他们已经进行了课程回顾和需求分析。此外,在创作过程中还需要教师掌握基本的化学概念,了解学生的情况。经过验证的学习前问题可以帮助教师更好地传达环境污染化学的基本概念,从而达到教师的学习目标。

Fundamental chemistry concepts on environmental pollution: Experts validation of pre-learning questions
The purpose of the research was conducting expert validation on environmental pollution problems based on the fundamental chemistry concepts. The type of research was design and development that involved three experts as validators. Data processing was carried out using SPSS ver.26 through the Kendall test. The values of Asymp.Sig. showed that pre-learning questions were valid in terms of the compatibility of pre-learning questions with indicators of the national curriculum and SDGs, compatibility of pre-learning questions with creative thinking indicators, and clarity of language use. The pre-learning questions were divided into ten indicators. Most of them asked students to describe of how greenhouse gases, heavy metal, and solid or liquid nano-plastic destroy environment. Students explained and wrote the chemical representations of those processes, namely macroscopic, sub-microscopic, and symbolic. Pre-learning questions were valid because they have conducted a curriculum review and the needs analysis. Besides, the creation process also involved teachers who mastered fundamental concept of chemistry and understood the condition of students. The validated pre-learning question is expected to help teachers deliver the fundamental concepts of chemistry on environmental pollution well so that teachers can achieve learning objectives.
