Abstract: The purposes of this study were: 1) to determine the process and to get the development of learning materials in accordance with Edmodo, 2) to decide whether the level of students probabilistic thinking that use learning materials with Edmodo better than the level of probabilistic thinking that use the existing learning materials or not.This study is a research and development (R&D). This study is divided into three stages namely the preliminary stage, the development stage and the testing stage or experimentation. Preliminary stage includes research and information collecting. The development stage includes planning and develop preliminary form product, preliminary field testing and main product revision, main field testing and operational product revision, operational filed testing and final product revision. The testing stage includes the qualitative analysis and quantitative analysis with the Kolmogorov-Smirnov test . Data analysis that used is descriptive analysis and the quality of learning materials based on the criteria of validity, practicality and effectiveness of learning materials. Determination of the final product is done by focus group discussion (FGD) between researchers and teachers or practitioners. Based on the study results obtained the following conclusions : 1) the preliminary stage is concluded learners at the level of the subjective and transitional; the development stage is conclude the obtained validity with an average of 3.57 of a media expert, 3.67 of subject matter experts; the practicality has exceeded the criteria above 75 % and the effectiveness gained an average response learners receive is 93.25 %; and from the result of FGD concluded that learning materials can be used in the process of learning in the curriculum 2013 and can be disseminated, 2) learning that use Edmodo learning materials is more effectively to improve the level of probabilistic thinking learners than the learning that use the existing learning materials.Key words: learning material, Edmodo, level, probabilistic thinking

Abstract: 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 âgoodâ, 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.Keywords: Learning Module, Mathematics Comic, Scale and Comparison.
