The aim of this study was to compare motivation of sixth-grade students engaged in instruction using reform-based curriculum with sixth-grade students engaged in instruction using a traditional curriculum. There were 273 sixth-grade mathematics students, 123 in the control group and 150 in the treatment group, involved in the study. This study took place in North Florida. The researchers used a questionnaire, the Course Interest Survey (CIS), administered to the students before and after a five-week of instruction. The paired-samples t-test, the independent-samples t-test, and ANCOVA with α = 0.05 were used to analyze the quantitative data. The study showed that there was a statistically significant difference in motivation between the groups favoring the treatment group. In other words, the reform-based curricula designed on the basis of van Hiele theory, compared to a traditional one, had more positive effects on students' overall motivation in learning geometry at the sixth grade level.
The aim of this study is to investigate the effects of using concept maps on the mathematics classes achievement of students. The sample consists of 71 students, who are in two sixth grade classes at a Secondary School in Turkey. One of the sixth grade classes was used as the experimental group and the other one as the control group. The equality of the groups was determined by t-test analysis on a pre-test. The research was carried out over four weeks. The control group studied with conventional teaching methods and the experimental group studied with a teaching method including the use of concept map. Achievment Test was used us a data source and t-test was used to evaluate the hypothesis. Results showed there was a significant difference between the control and experimental group based on results of the achievement post test. The experimental group was more successful than the control group, p=.000 (p<.05). Based on this results we concluded the teaching the subject "fractions" through the use of concept map increase the knowledge of fractions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
