摘要

本研究的目的是通过RADEC学习模型的实施,改进海洋污染物迁移的基本概念和化学表征。污染物在海洋中被溶解、电离甚至水解。本研究采用准实验设计,包括一组测试前和测试后设计。使用的仪器是四级诊断测试。它用于观察学生对海洋污染物迁移概念的基本概念和化学表征的改进。在课堂结束时,大多数学生的水平是缺乏知识,甚至缺乏科学概念。统计数据显示,学生的测试前和测试后存在显著的平均差异。这清楚地表明,RADEC学习模式对学生的基本概念和化学表征水平产生了影响。工作表引起的改进。它激发了学生们创造废物过滤器或化学产品的灵感,这些过滤器或产品可以吸收海洋中的废物,甚至可以创造亚微观的表现。

Fundamental concepts and chemical representations on sea pollutant migration: can it be improved through RADEC
The purpose of this research is to improve the fundamental concept and chemical representation of sea pollutant migration through the implementation of the RADEC learning model. Pollutants are solved, ionized, even hydrolyzed in the sea. The research employed a quasi-experimental design with a one-group pre-test and post-test design. The used instrument was four-tier diagnostic tests. It was used to see the improvement of students' fundamental concept and chemical representation on the sea pollutant migration concept. At the end of the class, most of the students' level was lack of knowledge 1 even scientific conception. The statistical data showed there was a significant mean difference between the students' pre-test and post-test, It clearly stated RADEC learning model gave an impact on students’ level of fundamental concepts and chemical representation. The improvement caused by the worksheet. It inspired students to create waste filters or chemical products that can absorb waste in the ocean even created sub-microscopic representations.
