To understand the concepts or principles in mathematics, children who have a concrete operational stage need physical objects that can bridge abstract concepts in mathematics. This research aims to evaluate the influence of coastal contextual learning media on a child’s understanding concept in the material of numbers counting operation. This research is a single-case research with the A-B-A withdrawal design. This research used dependent variable in the form of target behavior which consists of the understanding of integer counting operation concept material. Intervention in the form of the use of coastal contextual learning media was independent variable. The media used in this research were seashells that had been colored. The research subjects were 6th graders of one of the primary schools in Tarakan City of North Kalimantan Province, Indonesia. The instrument used to collect the data was a test consisting ten items. The data was analyzed with descriptive statistics in the form of analysis in conditions and among conditions. The research result shows that the coastal contextual learning media in the form of shells was effective to improve the understanding of concept in number counting operation for the research subject. It can be seen from the improvement of the correct answers on the test of understanding concept given.

沿海语境学习媒体对数数运算概念理解的单例研究

为了理解数学中的概念或原理，具有具体运算阶段的孩子需要能够连接数学中抽象概念的实物。本研究旨在评估沿海情境学习媒体对儿童在数数运算材料中理解概念的影响。本研究是采用 ABA 退出设计的单例研究。本研究采用目标行为形式的因变量，包括对整数计数运算概念材料的理解。以使用沿海情境学习媒体的形式进行干预是自变量。这项研究中使用的介质是经过着色的贝壳。研究对象是北加里曼丹省塔拉干市一所小学的六年级学生，印度尼西亚。用于收集数据的工具是一个由十个项目组成的测试。数据采用条件分析和条件间分析的形式进行描述性统计分析。研究结果表明，贝壳形式的海岸语境学习媒体有效地提高了研究对象对数数运算概念的理解。从所给理解概念测试中正确答案的提高可以看出。研究结果表明，贝壳形式的海岸语境学习媒体有效地提高了研究对象对数数运算概念的理解。从所给理解概念测试中正确答案的提高可以看出。研究结果表明，贝壳形式的海岸语境学习媒体有效地提高了研究对象对数数运算概念的理解。从所给理解概念测试中正确答案的提高可以看出。
