Students who have special needs also have the right to obtain an education as a provision for life, just like regular students. However, several learning tools for them are still very few. It is because some researchers always focus on standard students. Therefore, this study aims to develop visual-based mathematics teaching materials on integer arithmetic operations, one of which is deaf students. The development model used is a modified development model from the 4D model. Teaching materials that have been developed and tested on deaf class VIII students are suitable for use as a learning medium because they meet the criteria of being valid, practical, and effective. Valid because the average value of the three validators is 3.85. Furthermore, the practical standard is because the percentage of the average response score of students obtained is 80%. Finally, the effective criterion is that the average score of students trying to solve the test questions is 81. The results of this study contribute to providing alternative teaching materials for deaf students.

This study is development research, which aims at developing Natural Sciences (IPA) learning tools for SMP (junior high school) based on discovery learning oriented on problem solving skills and learning outcomes on acidic-base and salt material which is valid, practical and effective. The development model employed in this study referred to 4D development model, which consisted of define, design, develop, and disseminate. The learning tools developed are RPP, LKPD, BAPD, Media, and THB. The IPA learning tools for SMP based on discovery learning which had been developed was then validated by two experts. After being validated, the test of learning tools based on discovery learning was conducted at SMPN 36 Makassar in grade VII.9 with the total of 32 students. The results of the study reveal that the learning tools based on discovery learning developed which had been validated indicates that the mean score is 3.74 which is in very valid criteria. The learning tools based on discovery learning is stated as practical and effective, because the results of the practically test reveal (1) the implementation of learning tools based on discovery learning is in the average of M = 1.9 in the category of (1.5 ≤ M ≤ 2.0) meaning that the aspects and criteria observed on the implementation of learning tools based on discovery learning is in entirely implemented category, (2) the teacher gave a very positive response on the learning tools based on discovery learning with the percentage of 92.07%, and (3) the students gave a very positive response on the learning tools based on discovery learning with the percentage of 92.77%. The learning tools is also met the criteria of effective with the following results: (1) the improvement of problem solving skills of students from 27.22% becomes 74.50%, (2) the learning outcomes has met effective criteria that the average of the percentage is 83.48% with the classical completeness 87.50%, whereas, the improvement of learning outcomes based on N-gain test is 0.82 with high criteria. Therefore, the results of the study shows that the product of learning tools developed is categorized as valid, practical, and effective.

This study aims to determine the effectiveness of practicing problem-solving skills from ESD-based science learning tools. This research is development research with the ADDIE development model and a one-group pre-test post-test design. Data collection methods using validation and tests. Learning tools in all aspects are stated to be very valid so that they can be implemented. The pre-test average score was 52.96 and the post-test score was 79.84 with an N-gain score of 0.67 in the moderate category. This shows that students can be improve in problem-solving skills with ESD-based learning. Students can improved problem-solving skills in the Lapindo mud phenomenon by integrating the liquid pressure material (Archimedes Law and Bernoulli's Law) with the ESD concept (social, ecological, and economic). In terms of ecology, Lapindo mudflow can be overcome by applying Bernoulli's Law. In the economic sector, the overflowing Lapindo mud can be used as a building material. This is studied in the material of Archimedes Law. In the social point, students can communicate the results of problem-solving with the concept of ESD to the surrounding community.
