This study is development research, which aims at producing guided inquiry-based IPA (Natural Sciences) learning tools in energy and life system subject which is valid, practical, and effective, discovering the level of validity, practicality, and effectiveness of guided inquiry-based IPA learning tools in energy and life system subject developed. The development of learning tools employed Thiagarajan (Four-D) model which consists of four stages, namely defining, design, development, and dissemination. The test of learning tools was conducted to the students of grade VII.1 at SMPN 36 Makassar of academic year 2018/2019. Data collecting employed observation sheet and questionnaire. The data were then analyzed by using descriptive analysis technique. The products produce in this study are the lesson plan (RPP), student’s worksheet (LKPD), and student’s textbook (BAPD). The results of the validation on the learning tools developed, it is obtained the mean score based on the assessors which met the valid criteria and all of the components of learning tools are valued as reliable. The result of the field test on the practicality of learning tools developed shows that there is consistency between the result of experts’ perceptions and observers’, which is both gave high criteria or good. The learning tools are also effective to be applied because the result of the field test indicates that there is consistency between the result of experts’ perceptions and observers’. The result of experts perceptions gave the effectiveness result with high criteria or good. The result of observation on four indicators of effective criteria were all met.

This study aims to improve the skills of writing persuasive speech texts by using a multimedia-assisted Problem Based learning model for grade 9J students of SMP Negeri 2 Mataram. This research method used classroom action research. Data were obtained by using field notes, observations, tests, and documentation in the form of assignments. The data analysis technique in this research is descriptive analysis. The results of this study indicate that the application of the Problem Based Learning model assisted by multimedia can increase the activeness of students in learning to write persuasive speech texts. The increase can be seen from the percentage of activeness of 65.71% in the first cycle to 94.29% in the second cycle. In addition, the multimedia-assisted Problem Based Learning model can improve the skills of writing persuasive speech texts. This can be seen from the writing results of students who achieved the KKM in the first cycle of 74.29%, increasing to 100%.

The ability of mathematical representation is an ability that students should have in order to assist in interpreting problems into verbal, visual, and symbolic forms. The low ability of students' mathematical representation and learning tools that are made by the teacher has not facilitated enough the ability of mathematical representation the main objective of this study. Researchers developed learning tools consisting of syllabus, lesson plans, and student worksheet using the Problem Based Learning model to improve students' mathematical representation skills. The development model used is the Borg and Gall’s model. The instruments used were validation sheets and student response questionnaires. The data analysis technique used is the analysis of validity and practicality. The result of the percentage of validity shows that the learning device is included in the valid category with an average syllabus percentage of 92.18%, RPP is 93.64% and LKPD is 93.06%. The student response questionnaire analysis showed that the device was included in the very practical category with an average of 92.2%. The tools developed by researchers have met the valid and practical categories to facilitate the mathematical representation abilities of students.

This research is motivated by the real condition that students do not understand the concept of linear equations and one variable linear inequality and the teacher tries to improve understanding of these concepts. An alternative to solve this problem is by applying experiences, language, pictures, symbols, application (ELPSA) learning model using sticky tape media. This study aims to improve students' understanding of concepts in the subject matter of linear equations and inequalities with one variable in junior high school mathematics. Research subjects, students of SMPN Bulo Odd Semester 2018/2019 Academic Year class VII A consisted of 27 people. Methods of data collection, observation, tests, questionnaires and field notes. The implementation is carried out in 3 cycles, each cycle consisting of planning, implementing, observing, and reflecting. The data analysis technique was carried out in a descriptive qualitative manner. Descriptive analysis, to describe the implementation of the learning model and calculate the percentage of students who completed. Qualitative analysis using flow methods, namely data reduction, and drawing conclusions or verification. Conclusion (1) Learning with the ELPSA model with stick tape media can improve the concept of linear equations and inequalities of one variable in students of SMPN Bulo class VII A. (2) The ELPSA learning model with stick tape media can improve learning outcomes of linear equations and inequalities of one student variable SMPN Bulo class VII A.
