The most significant concern in teaching mathematical concepts is developing and improving mathematical communication skills. However, the reality reveals that communication skills possessed by students are still relatively low. This causes students’ difficulty in understanding the material, solving problems, and conveying mathematical ideas both in oral or written form. Furthermore, students’ teaching material is not adequate to support the expected learning goals. It creates students’ difficulty in understanding the materials and it doesn’t integrate mathematical communication skills. This study aims to develop teaching materials in the form of mathematics module based on reciprocal teaching to improve students' mathematical communication skills. This is a research development that employs Four-D model. Subjects of the study are the teachers and the seventh grade Junior High School. In collecting the data, the researchers employ observation, interviews, questionnaires, and mathematical communication skills test. The results show that teaching material in the form of module that is assessed by experts has reached excellent criteria in terms of material and media. The module is also practically used by students and teachers in the learning process. It means, module based on reciprocal teaching can improve students' mathematical communication skills

This research is motivated by the lack of mathematics teaching materials that can make students learn on their own. The teaching material can be created by teachers as they are the ones who possess the knowledge about their students’ characteristics. Further, learning materials are a set of materials (information, tools, or texts) that can aid teachers and students to carry out the learning process. The two-variable linear equation system (SPLDV) is one of the mathematics materials taught to eighth-grade students of junior high school; it contains problems related to daily life. However, it is found that this material is still difficult to master by most students. Therefore, it is necessary to develop the SPLDV teaching materials that can help students learn and solve problems as well as be used as examples by teachers in developing other materials. This research aimed to make problem-based SPLDV teaching materials. The research method refers to the Four-D Model by Thiagarajan, Semmel, and Semmel (1974). It consisted of defining, designing, developing, and disseminating. The results showed that problem-based SPLDV teaching materials could be used in learning activities as the students and the teachers had shown their positive responses after going through expert assessments. This study also suggested that the teachers use this teaching material and adopt teaching materials for other similar materials.

As a case study of the introduction of efficient and effective teaching materials and methods that enhance students' technological literacy in different areas despite the relative lack of classroom hours devoted to technology education in Japanese junior high schools, a front-loaded horn speaker system was proposed as a component of multipurpose teaching materials and methods integrating several areas. Following the development of teaching materials and lesson plans, their effectiveness was evaluated through implementation. Acoustic measurements showed that the horn speaker provided high efficiency in the midrange. Moreover, the results of a post-lesson questionnaire administered to junior high school indicated that the speaker system was highly effective as teaching material. It was therefore concluded that the new design enhanced not only student interest but also their technological literacy, as they demonstrated an understanding of the acoustic mechanism and high satisfaction with their final products.

Measurement And Control

The rapid growth of the information technology industry in recent decades requires an increasing number of programmers and engineers, as well as an excellent training environment for relevant human resources. Currently, school curricula promote information education and, since 2012, “measurement and control by programs” have become compulsory topics of study in the technology and home economics (technological field) class in junior high schools. In addition, it has been determined that programming education will be made a compulsory topic in elementary schools from 2020 onward. Thus, programming education is included in the mandatory education program and, accordingly, various associated teaching materials have been developed and distributed to date. However, adequate steps have not been taken to improve the information education skill of the teachers who use the aforementioned teaching materials. In particular, only very few teachers understand the essence of programming control, such as the role played by a program in measurement and control. Hence, there is an urgent need to train teachers to make them capable of providing programming education in school settings. Hence, in this study, we develop a teaching material that helps teachers understand the flow of measurement and control by program using an optical distance sensor and an actuator and design a class practice for the students in the faculty of education. Finally, based on this education practice, we discuss an educational effect of the aforementioned teaching material and its applicability in junior high school settings.
