The purpose of this study is to assess high school students' abilities to comprehend graphs, and to afford fundamental data to find a teaching method to improve their graphing abilities. As a result of this study, High school students' abilities to comprehend the types of graphs were different according to the types of graphs. They comprehended more column graph, line graph and circle graph than 100% bar graph and scatter. They were familiar with column graph(84.0%) and line graph (77.3%), and when forms of graphs were given, they gave right answers in order of column graph (86.6%), circle graph(77.3%), dot graph(71.4%), line graph(70.6%), scatter(22.7%) and 100% bar graph (16.0%). Students need to have many opportunities to encounter and be familiar with various types of graphs. High school students' abilities to comprehend the usages of graphs were lower than their abilities to comprehend the types of graphs in general. They gave right answers in order of column graph(39.5%), line graph(31.1%), circle graph(21.0%), 100% bar graph(16.0%) and dot graph(6.7%), and nobody gave right answer to usage of scatter. When the text with data were given, they chose proper type of graph well with circle graph(78.2%), but they had poor abilities to choose proper type of graph with other types of graphs. Therefore there is a need to teach them about accurate usages of graphs and provide them various activities to choose proper graphs with various experimental data.
Abstract
The purpose of this study is to assess high school students' abilities to comprehend graphs, and to afford fundamental data to find a teaching method to improve their graphing abilities. As a result of this study, High school students' abilities to comprehend the types of graphs were different according to the types of graphs. They comprehended more column graph, line graph and circle graph than 100% bar graph and scatter. They were familiar with column graph(84.0%) and line graph (77.3%), and when forms of graphs were given, they gave right answers in order of column graph (86.6%), circle graph(77.3%), dot graph(71.4%), line graph(70.6%), scatter(22.7%) and 100% bar graph (16.0%). Students need to have many opportunities to encounter and be familiar with various types of graphs. High school students' abilities to comprehend the usages of graphs were lower than their abilities to comprehend the types of graphs in general. They gave right answers in order of column graph(39.5%), line graph(31.1%), circle graph(21.0%), 100% bar graph(16.0%) and dot graph(6.7%), and nobody gave right answer to usage of scatter. When the text with data were given, they chose proper type of graph well with circle graph(78.2%), but they had poor abilities to choose proper type of graph with other types of graphs. Therefore there is a need to teach them about accurate usages of graphs and provide them various activities to choose proper graphs with various experimental data.
