Abstract

The process of reasoning has a very strong connection with mathematic world, especially on problem solving skills. But in real life, teachers usually use textbook to measure how much do their students understand materials taught by the teachers. Hence, it is necessary to understand completely do the widely used mathematic textbook has led students to increase their mathematic reasoning skills. The method used were descriptive qualitative, with Competency Test’s problems in 2013 Curriculum text book revised in 2014 for 1 th grade used for research subjects. Documentation method was used as data collection method. Problems analysis guide was based on mathematic reasoning skills indicator according to NCTM. The analysis result tells that from 225 problems analyzed there were 76 problems fulfilled the indicator 1, 110 problems fulfilled the indicator 2, 30 problems fulfilled the indicator 3 and 183 problems fulfilled the indicator 4. Analysis also shows that based on mathematic reasoning skills, from 225 problems there were only 8 problems haven’t fulfilled the mathematic reasoning skills with 3,56% presentation number. While the rest there were 217 problems have fulfilled the mathematic reasoning skills with 96,45% presentation number with 49 problems with 21,78% presentation number have a good criteria, 80 problems with 35,56% have an average criteria and 88 problems or 39,11% have a low criteria.

Abstract

The PBL model used by the teacher in learning mathematics in SMP N 2 Karanganyar is considered unable to solve problems in class. The teacher has involved students in learning, students are required to conduct interviews and observation activities in the field. Teacher expectations with these activities, students can get used to solving math problems in class. But when students are given different problems, students have not been able to make the solution. Flipped Classroom is an alternative learning model that can overcome these problems. This study aims to determine (1) whether students' mathematical problem solving abilities through the flipped classroom model can achieve KKM, (2) students' mathematical problem solving abilities using the flipped classroom model are better than students' mathematical problem solving abilities using the PBL model. This type of research is a quasi-experimental. The instrument used in this study is a test. Analysis of the data in this study using the proportion test and t test. The results of this study indicate that: (1) the problem-solving ability through the flipped classroom model can achieve KKM, (2) the problem-solving ability of students with the flipped classroom model is better than the PBL model.

Abstract

Learning activities at SMK Muhammadiyah Kesesi are still less use of instructional media, teachers still use the available package books in school and power point at the time of learning so that students feel bored. This research develops electronic teaching materials based on flipbook maker linear class X material program at SMK Muhammadiyah Kesesi. The purpose of this research is to know the validity and the practicability of the developed electronic materials. The research conducted using the Borg & Gall development model included in Putra (2012:120-121). The steps of the research are: 1) research and data collection; 2) development of initial product type / shape; 3) initial field trials; 4) field implementation test; 5) product improvement. There are 8 validator in this research and there are 28 students as respondent. Based on the research results obtained the average total criteria from the validator V a  4, 1. According to the validation criteria, it can be conclud that the electronic teaching materials using kvisoft flipbook maker application on the material linear, class X SMK is said to be valid. While the calculation of the value of the practicality of electronic materials using kvisoft flipbook maker application on material linear class X SMK obtained from the student response questionnaire is 85,9 %. It means, the developed electronic teaching material is declared to be practical. Therefore, it can be concluded that the electronic teaching materials using kvisoft flipbook maker application on material linear class X SMK is suitable to use as one of the learning resources.

Abstract

The rapid progress of science and technology in the world of education underlies the existence of learning by utilizing Information Technology as a learning medium, one of which is known by the term web-based learning. The development of instructional media using Adobe Dreamweaver CS6 application with inquiry method in the tangents of circle alliance aims to overcome the problems in the learning process in SMP Muhammadiyah Pekajangan which still use simple learning media. This development research uses the Borg & Gall development model. The stages are research and data collection, product design, product validation, product trial and product improvement. The purpose of this study is to develop a quality learning media by testing the validity and validity of the learning media. Based on the result of the research, the average of total aspect from all validator 4.7. While the calculation of the value of practicality of learning media from questionnaire response obtained percentage of 85.19%. According to the criteria of validity and the criteria of practicality it can be concluded that the learning media developed valid and practical.

Abstract

The purpose of this research was to develop valid tools for mathematic lessons. In this research, the developed lesson was basic mathematic capita selecta textbook based on Telaah, Eksplorasi, Rumuskan, Presentasikan, Aplikasikan, Duniawi dan Ukhrowi (TERPADU) to increase student’s problem solving in mathematic. The lesson tools which would be developed were: (1) Syllabus, (2) Semester Development Plan (SDP), (3) Textbook, and (4) Mathematic Problem Solving Skill Test, for students of Mathematic Educational Department, Wiralodra University. The development model used were lesson tools’s developing using Plomp modificate-model. The validity of lesson tools were assested by expert team validation and colleges. The result gained validation for tools developed by five experts and gained overall average score “usable”. This validation counted as an excellent category thus the tools are valid.
