Abstract

One of the goals of mathematics learning is that students are expected to have good understanding mathematics concept abilities. The application of discovery learning model in the process of learning mathematics is one of the learning modelsthat can improve students understanding of mathematics concepts. The learning process uses the discovey learning model so that students can find the concepts of the material being studied and can conclude their own concepts that have been found based on their ability to understand. This research aims to determine that: (1) students understand the mathematics concepts of discovery learning model in effective;(2) students understand the mathematics concepts of conventional learning model in effevtive; (3) the effectiveness of discovery learning model and conventional learning for understanding mathematics concepts, and to know in 11th Senior High School at SMA N 1 Gamping. This type of research is an experimental quasi experiment with research design Posttest Only Control Design. The population in this study were students of class XI IPS SMA N 1 Gamping. The sample in this study was class XI IPS 1 as an experimental class and class XI IPS 2 as a control class. The instrument used in the study was the observation sheet of the implementation of learning and the students understanding mathematics concepts test questions. Analysis of the data used is the t-test and the prerequisite test used are normality and homogeneity test. The result showed that using discovery learning model and conventional learning model were effective that students understand the mathematics concepts, and learning using discovery learning model was more effective than conventional learning model when viewed from students understand the mathematics concepts.

Abstract

The research purpose was to produce learning material as the quality of Student Work Sheets based on contextual learning to facilitate Mathematics concept understanding skill of Junior High School student 7th Grade at triangle material and to describe the quality of Student Work Sheets that has a valid, simple and effective qualification. Student Work Sheets development based on Ministry of Education development model that adapted from Borg and Gall procedure development through some steps: (1) doing product development analysis, (2) developing beginning product, (3) expert’s validation and revision, (4) small-scale field test and product revision, and (5) significant scale field test and last  product. Student Work Sheets quality described based on the marking result of material expert, media expert, and mathematics teacher for the validation aspect, student respond questionnaire and observation sheets of learning application for simplicity aspect, also a post-test question for affectivity aspect. The research result showed that the quality of Student Work Sheets product in validation aspect fulfill good and very good criteria based on the mark from a material expert, media expert, and assessor with the average score for each aspect was 4,19; 4,31; and 4,23. Simplicity aspect fulfills good and very good criteria based on the result of student respond questionnaire and observation sheets of learning application with the average score for each aspect was 3,55 and 93,68%. However, for affectivity aspect fulfill good criteria based on student post-test with the average score was 79,17 from the maximal score was 100 and completeness percentage was 69%.

Sekolah Penggerak is a school that implements an independent curriculum. SMP N 4 Patuk is one of those who are included in the first batch. End of school year activities must provide reports on student learning outcomes and confirmation of grade promotion. The first batch of driving schools have not found examples or best practices in compiling the document. Thus, there is a need for mentoring and strengthening of the learning committee in completing grade promotion documents. This is the basic foundation for the implementation of service and is carried out through three steps, namely preparation, implementation, and closing. At firts stage, the team communicated for permits from both schools and universities. In addition, the service team prepares materials related to the preparation of learning outcomes reports.

Abstract

Complex problem solving is a cognitive skill to obtain information about obscure problem situations and use knowledge to achieve self-formulated goals in solving problems. The purpose of this study is to describe the level of complex problem-solving ability of students who are prospective mathematics teachers. This research uses descriptive qualitative methods. The subjects of this study were 3 prospective mathematics teacher students in semester VII of the Mathematics Education Study Program at Tidar University. The main instrument is the researcher himself, supported by complex problem-solving tests and interview guidelines. The data studied are answer sheets for complex problem solving tests which are then analyzed through the stages of data reduction, data presentation, and drawing conclusions. The results showed that the level of complex problem-solving ability is divided into 3, namely novice, medium, and proficient.
