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.

The objectives of this study are aimed at: 1) analyzing the effect of Information Literacy Learning model on the learning outcome of eighth-grade students of Public Junior High School 2 of Kendit in Situbondo in social science subject; 2) analyzing the effect of Problem-based Learning model on the learning outcome of eighth-grade students of Public Junior High School 2 of Kendit in Situbondo in social science subject; 3) analyzing the differences in the learning outcome of eighth-grade students of Public Junior High School 2 of Kendit in Situbondo between the application of the Information Literacy Learning model and Problem-based Learning. This research is a correlational study. Based on the results of data analysis, the study has drawn several conclusions. First, there is a very significant influence, marked at 53.7%, of the Information Literacy Learning on learning outcome. Second, there is a significant effect of the Problem-based Learning on learning outcome, as evinced by a correlation magnitude of 57.7%. Third, the analysis has identified no significant difference between Information Literacy Learning and Problem-based Learning on learning outcome shows. This shows that both learning models are equally well applied to improve learning outcome.
