This study aims at: 1) investigating elegibility of comic-illustrated mathematics module on the materials of scale and comparison for grade VII students of SMP/MTs, 2) investigating the effectiveness of comic-illustrated mathematics module on the materials of scale and comparison for grade VII students of SMP/MTs. This study was a research and development (R & D) in mathematics learning at SMP/MTs. The applied development model was a development model postulated by Borg and Gall modified by Sukmadinata, which consists of three stages, including: 1) preliminary research, 2) development, and 3) field testing, each of which contains several steps. The product validation process was carried out by material experts, media experts, and respondents. The effectiveness testing for the module carried out in MTs Negeri Ngawi. The data collecting instrument used was the mathematics performance test. The content validity was measured by validators. The reliability test for measuring the test instrument applied KR-20 formula and the discriminatory power used product-moment correlation formula by Karl Pearson. The balance test was carried out by using t-test. The prerequisite tests covered normality test using Lilliefors testing method and homogeneity test using Barttlet method. The experimental design for this research was randomized post-test-only control group design. On the basis of the research findings and development, the research is concluded: 1) the comic-illustrated mathematics module was feasible to be used in learning process, the comic-illustrated mathematics module is considered feasible when the evaluation result from retriever is "good", 2) the average students learning achievement in experiment class is better than that in control class, this conclusion is in accordance with the hypotheses proposed, namely learning with comic-illustrated mathematics module on the materials of scale and comparison for grade VII of SMP/MTs is more effective than direct learning without comic-illustrated mathematics module.

Understanding a concept is needed by students as a prerequisite in solving mathematical problems, because by understanding a concept students can explain and describe in detail a thing he understands using his own language. This study aims to describe the understanding of junior high school students in solving mathematical problems in terms of learning styles, namely visual, auditorial, and kinestetik. This research is a descriptive research with qualitative approach and data collection technique is done by written test and semi structured interview. Subjects in this study consisted of three students who have different types of learning styles with relatively equal mathematical abilities and have good communication. If triangulation in two times the data retrieval process has received data that tends to be the same then the data is considered valid and made the conclusion. In the first and second data retrieval process concluded that the visual subject in understanding the problem and preparing the plan had a formal understanding whereas in carrying out the plan and checking back has an instrumental understanding. Auditorial subject when understanding the problem has an instrumental understanding, when developing a plan has a formal understanding, when implementing the plan has a relational understanding, as well as in checking back having a formal understanding. And kinesthetic subjects have a formal understanding when understanding the problem, relational understanding when drawing up a plan, as well as in carrying out the plan and checking back has an instrumental understanding.
