Student needs a help service study that gets to help increase their studying achievement. The research was aimed to: (1) valid student work sheet with reading basis of quadrangle by using CIRC (Cooperative Integrated Reading and Composition) method; (2) measure the effectiveness of the learning material which used student work sheet with reading basis for teaching quadrangle in seven graders by using circ method; (3) describing practicality by used student work sheet with reading basis for teaching quadrangle in seven graders by using CIRC. This type of research used model of 4-D which consisted of the phase of preliminary investigation, the phase of define, design, develop, and disseminate. But, in this reaserch just until phase of develop. It has also been developed student worksheet. The subjects of the research were the seventh graders, with Clutser Sampling, gotten two classes which is the experiment class and control class. The research data were collected from (1) validation sheet; (2) Observation sheet; (3) questionnaire, and (4) the test. The results showed (1) student work sheet developed have been declared valid by the validator with an average score of 3,4 from supreme scores 4, (2) teacher ability observation result gotten 3,6 of supreme scores 4 and student response are gotten 87% one mean developed tool practical; (3) result from experiment showed the average achievement of those trial class which performed better than those of control class. Base explanation upon, concluded that the development of student work sheet with reading basis for teaching quadrangle in seven graders by using CIRC accomplishes valid tools, practical purpose and effective learning. So, Development student work sheet be reached

STRATEGI TRUE OR FALSE DENGAN MEDIA KARTU INDEKS PADA MATA KULIAH TEORI GRAF

This study aims to determine the activities of students in learning subjects through True or False strategy of graph theory by media index cards. Observations show a more focused student activity because students already know the material of what will be learned through the index cards that they get in early learning, and they also know the form of matter or issue that they get when studying the learning material on which they will carry. Students focus on the material presented by the lecturers. At the end of the students' learning spirit in concluding that material has been obtained. Lecturers also seem satisfied when getting feedback from students on material that has been given to the student lecturer. Keyword: true or false, cards, graphs, medi

The Error in Drawing Graphic of Quadratic Function in PBL Model by Using True or False Strategy with GeoGebra-Assisted

Quadratic function is one of the important topic in mathematics. The purpose of this study is to describe the mistakes made by students when drawing a quadratic function graph. In this research, the focus of the problem is what type of mistakes made by students in drawing a graph of quadratic functions. The form of error here referred to an error in doing the exercise of drawing quadratic function graph in learning with the PBL model using a true or false strategy assisted by GeoGebra application. The conclusion of this research states that the error in drawing quadratic function graph is dominated by procedural errors. PBL model with true or false strategy with the help of GeoGebra application can be an alternative learning to overcome students' mistakes in drawing quadratic function graph

PENGEMBANGAN MEDIA PEMBELAJARAN MATEMATIKA BERBASIS APLIKASI ANDROID LINES AND ANGLES PADA MATERI GARIS DAN SUDUT UNTUK SISWA SMP/MTS

Today's technology is rapidly advancing. Educators must keep pace with technological progress. The increasing use of smartphones and tablets among students and teachers has spurred the development of more innovative and interactive Android-based learning media. Android-based learning resources are required to assist technological growth, especially for pupils in junior high school. This study aims to develop a valid Android application-based math learning tool and ascertain teachers' and students' reactions. The 4D development model put forth by Thiagarajan (1974) is the basis for this study's research and development (RD) approach. Analysis was completed using student responses, teacher feedback, and expert validation. The findings revealed that the android-based mathematics learning media for seventh-grade students' "lines and angles" topic achieved an average validity score of 4.253, indicating it's highly valid. Teachers' responses had an average score of 4.3, deeming the media very helpful, and student feedback had an average score of 3.87, declaring it helpful. Based on the results, the proposed learning media is feasible as a learning supplement and is worthy of further development

Statistical Literacy Process of Prospective Mathematics Teachers: A Case Study of Pisa Model Problems

This study explained the use of the statistical literacy process for prospective mathematics teachers in solving PISA model problems. The applied approach was a qualitative descriptive approach The researchers grouped the subjects into low, moderate, and high ability categories based on the previous academic test results. Then, the researchers collected the data from statistical literacy skill tests and interviews. The researchers analyzed the data by reducing, presenting, and drawing conclusions. In this research, the statistical literacy processes consisted of data orientation, data process, data interpretation, and data evaluation. The results showed that moderate and high categories students could focus on math problems. The evidence was the students understood the given information. The middle and high-category students had excellent statistical literacy processes. However, the high-category students could explain the statistical literacy process systematically and carefully. The high-category students could demonstrate their writing, implementing, and interpreting strategies of the obtained answers

PENGEMBANGAN MODUL STATISTIKA DESKRIPTIF BERBASIS PEMECAHAN MASALAH

Penelitian dan Pengembangan ini difokuskan untuk mengembangkan modul statistika deskriptif berbasis pemecahan masalah. Modul dikembangkan menggunakan tahapan perencanaan, perancangan, dan pengembangan yang diadopsi dari model pengembangan Thiagarajan. Modul dikatakan valid berdasarkan penilaian validator; dikatakan praktis berdasarkan hasil angket respon mahasiswa; dan dikatakan efektif berdasarkan hasil ujicoba modul berbasis pemecahan masalah. Hasil validasi menunjukkan bahwa modul memenuhi kevalidan dengan rata-rata 3,45 dari rata-rata maksimal 4,00. Hasil angket respon memenuhi kriteria kepraktisan dengan rata-rata 4,47 dari rata-rata maksimal 5,00. Sedangkan hasil tes kemampuan pemecahan masalah mahasiswa memenuhi kriteria keefektifan yang ditunjukkan dari hasil uji One-Sampel t-Test bahwa pemecahan masalah mahasiswa telah mencapai KKM yang ditentukan. Berdasarkan ketiga hasil tersebut menunjukkan bahwa modul berbasis pemecahan masalah memenuhi ketiga kriteria tersebut, yaitu: valid, praktis, dan efektif. Research and development are focused on developing descriptive statistics based on problem-solving modules. Modules produced using the stages of planning, design, and development adopted from the Thiagarajan development model. Modules are said to be valid based on validator ratings. They are supposed to practice based on the results of the student response questionnaire; and assumed to be effective based on the results of the module-based problem-solving trials. The validation results show that the module meets validity with an average of 3.45 out of a maximum of 4.00. The response questionnaire's results matched the practicality criteria, with an average of 4.47 out of a maximum of 5.00. While the test results of students ' problem-solving abilities meet the effectiveness criteria shown from the results of the One-Sample t-Test that students' problem solving has reached the specified KKM. Based on the three results show that the problem-based module meets the three criteria, namely: valid, practical, and effective
