Pengembangan Modul Program Linier Berbasis Pembelajaran Mandiri

Modules are teaching materials that are often used in lectures. Modules can be used independently by students and are not spared by the guidance of lecturers in the course. The purpose of this research is to develop a linear program module based on independent learning by using the following steps: defining, designing, and developing. The linear learning module based on independent learning is validated by media experts, material experts, and linguists. Measurement of the validity of this module with a validation sheet and practicality in the value of the questionnaire given to students. Module development is explained qualitatively while data from the validation sheet and questionnaire are analyzed quantitatively. The results of the validation of the presentation, content, and language by media experts, material experts, and linguists obtained values ​​for presentation validation of 4.00, content validation obtained a value of 3.6, and language validation obtained a value of 3.83 which means that the module content the independent learning based linear program is valid in terms of presentation, content, and language. While the analysis of the practicalisation questionnaire by students obtained a value of 90% that the linear program module is based on independent learning in the practical category. Practicality can be seen from attractive and systematic appearance, using problem solving steps, clarity of material content presented, ease of use of modules, and words used are easy to understand according to characteristics college student.

Kemampuan Literasi Matematis Siswa pada Pembelajaran Model Problem Based Learning (PBL)

Students’ ability to mathematical literacy is very important in their math learning process. Less ability of mathematical literacy as students’ way of thinking, argumentation and creating is no improvement so they face difficulties in solving math problems in their learning process related to real life. The analysis of the result from students of SMP Kristen 1 Mollo Selatan shows that they are still a low inability of mathematical literacy. The effect is questions used as exercise are common questions and not related to real life. To solve this problem, the researcher implemented Problem Based Learning (PBL) as a teaching literacy to improve students’ mathematical literacy abilities. This study will compare two classes in which one of them treated with PBL one of the other ones was not treated with PBL. A quasi-experiment quantitative method that used in this study with nonequivalent control group design. Two classes were selected as the sample by using simple random sampling. An essay test related to students’ mathematical literacy ability was used as the instrument to collect the data. The analysis technique in this study was an independent sample t-test to the result showed that the class which was treated used the PBL method was better than the class which was not treated used the PBL method. Students’ mathematical literacy ability in the PBL class was significantly proved in the high category with the score gain 0,8.

Students’ Understanding Of Mathematical Concepts Through The Guided Inquiry Learning

The ability to understand concepts is very important and becomes the basis for supporting the solving of mathematical problems. The connection between one concept and another concept and one topic with another topic is a characteristic of learning mathematics. The relationship requires that each student must have the ability to understand the concepts well, but it cannot be denied that the ability to understand mathematical concepts is still low, as happened to theLangke Rembong 4Junior High School students. Learning innovation needs to be done to achieve a good understanding of concepts. This study aims to compare the understanding ability of mathematical concepts of students who follow a guided inquiry learning model with students who take direct learning. The research design uses Posttest only control group design. The population is all eighth grade students of Langke Rembong 4 Junior High School, totalling230 students. Sampling is done by random sampling with equality test between classes.It is then obtained class VIII A as the experimental class and class VIII C as the control class. Data collection uses tests in the form of description questions. Data analysis uses t-test with normality test and homogeneity test for the assumptions. The results show that the students who follow the guided inquiry learning have higher understanding of mathematical concepts than those who are taught with direct learning model. Keywords: inquiry, understanding of mathematical concepts
