This study aimed to develop a student worksheet on the Pythagorean Theorem utilizing the Realistic Mathematics Education (RME) approach, designed to meet validity and practicality standards to enhance the mathematical connection abilities of 8th-grade students. The research adopted the 4D development model, which includes the stages of Define, Design, Develop, and Disseminate. To ensure the validity of the student worksheet, three experts conducted a comprehensive validation process. Feasibility data were collected through trials involving 8th-grade students. The validation results indicated a score of 90.77%, categorized as "very valid." Small group trials yielded a practicality score of 89.98%, categorized as "very practical." Furthermore, large-scale trials demonstrated an average score of 89.29%, also categorized as "very practical." These findings highlight the effectiveness of the RME approach in facilitating students' mathematical connection abilities through the Pythagorean Theorem material. The developed student worksheet was proven to be valid, practical, and highly beneficial for supporting the development of mathematical connections among 8th-grade students.

Developing the ability of absolute thinking is needed inmathematic class where the subject has a characteristic as a branch ofscience which the object of study is abstract-natured and related with apattern of thinking. Basic mathematics is one of the courses that can developstudent’s ability to think. The results acquired by the students are still notmaximized; this is because the students struggle to develop their ownknowledge to form concepts. Student’s activities in the learning process areonly skill-natured in solving problems. One of the learning methods that canbe implemented is the Modified Moore method. This research aims todiscover the effects of mathematical thinking capabilities with the ModifiedMoore Method towards the learning achievement of Basic Mathematic II ofChemistry study program from the FKIP of Universitas Riau in the evensemester of 2013/2014 academic year.

In conveying the concept of mathematics in a concrete manner so that it is easily accepted by participants in the mentally retarded education, tools/media are needed. One of the media developed in this study for mentally retarded students is Ceker media and space building media. This study aims to produce Ceker learning media on number material and spatial shapes on blocks and cubes for mild mental retardation students at SMPLB Pekanbaru that meet valid and practical criteria. The research method used is the Borg and Gall development model. Collecting validation data for the addition and subtraction of integer operation materials was carried out by providing validation sheets to three experts. Practical data collection was carried out by distributing questionnaires to SMPLB mental retardation students using a Likert scale . The learning media of Ceker and building spaces that have been validated by 3 validators are very valid with a percentage of 93,3. The development of learning media for Ceker cards and building space for mild mentally retarded students has met the very practical criteria with a percentage of 100%. Based on the results of the research and discussion, it was concluded that the learning media of Ceker and building spaces (blocks and cubes) for mild mental retardation students at SMPLB have met the criteria of being very valid and very practical.
