The program for strengthening character education is only carried out in several pilot schools so that there is not much information available to what extent character education has actually been carried out in other schools, especially in non-piloting schools. This study aimed to measure the feasibility of strengthening character education in non-piloting schools. The population in this quantitative descriptive study was teachers at junior high school in Malang. The sampling technique used was purposive sampling. The subjects involved in this study were six teachers of Junior High Schools 20 of Malang, Junior High Schools 27 of Malang, and Muhammadiyah 1 Junior High School. Data collection used questionnaires and analysed descriptively statistically. The results of the study showed that the three schools have implemented character strengthening programs seen from the ten assessment components i.e. pre-assesment, programme socialization, vision, programme design, class-based implementing, school culture strengthening, social partisipation, core value implementing, and evaluation. These results indicated that character strengthening has become a positive habit but not yet optimal. The results of this study can be used as a basis for identifying appropriate follow-up steps for improving achievement of character strengthening in schools.

At this time, many students think that learning mathematics is difficult to understand. While Powtoon animation video-based mathematics learning media is still rarely applied, students feel bored. They do not understand the concept of material when the learning process uses the lecture method. The purpose of this study was to determine the effectiveness of using Powtoon animation video-based mathematics learning media on the material for the Two-Variable Linear Equation System in Junior High School. The type of approach used is a pre-experimental quantitative approach by applying a one-group pretest-posttest design. The research population includes all students of class VII-A at SMP NEGERI 1 NGIMBANG for the academic year 2020/2021, with 32 students consisting of 8 male students and 24 female students. Data collection techniques using tests and questionnaire sheets. While the data analysis technique used is normalized gain. The data obtained show differences in students' test results using the Powtoon animated video and before using the Powtoon animated video. The difference was seen from the average score of the students' test results before using the media of 36.41 and after using the media of 92.58. In addition, the research results from the N-Gain Test results show that the use of Powtoon animation video media is effective in learning mathematics. It is evidenced-based on the results of the expert test and media validation by obtaining 85% and 83.75%, which means that it belongs to the outstanding category. In comparison, the results of the student response questionnaire of 81.29% belong to the outstanding category. Students' test results get an average of 0.88% from the n-gain, which shows a high classification. This study indicates that Powtoon animation video media is effective in learning mathematics compared to learning that only uses the lecture method. 29% of it belongs to the outstanding category, then through the test results, students get an average of 0.88%, which is obtained from the n-gain, which means it shows a high classification. This study indicates that Powtoon animation video media is effective in learning mathematics compared to learning that only uses the lecture method. 29% of it belongs to the outstanding category, then through the test results, students get an average of 0.88%, which is obtained from the n-gain, which means it shows a high classification.

This research’s purpose is to describe the mathematical errors of civil engineer college students in subject Calculus II. The research’s method uses a qualitative approach that are reducing data, serving data, and conclude. Based on the research, it found that the major error to solve the problems of Calculus II is manipulating algebra form. The error of calculating is the second one after the error of manipulating algebra form. The researcher also finds that even the college students choose the right formula to solve the problems, they make an error in implementing the formula that they were chosen.

This study aims to effect of the TGT learning model on student’s creativity and comprehension of concepts in mathematics learning. This study used quasi-experimental research. The population in this study were 256 students of class VIII SMP YPPSB. The research sample was obtained in class VIII-H of 32 students as the experimental class and class VIII-D with total of the students were 31 students as the control class. The test used to analyze the research data was the Independent Sample T-test on the posttest results. The results of the study showed that creativity and comprehension of concepts using the TGT learning model was better than the class that used conventional learning. The average creativity used the TGT learning model tcount = 4.080 and the average comprehension of the concept of tcount = 11.012 with ttable = 2.00 which means tcount> ttable. Thus, the TGT type learning model has a significant influence on student’s creativity and comprehension of concepts in mathematics learning.

Pelaksanaan pembelajaran secara online pada masa pandemi covid-19 ini menuntut guru untuk dapat meningkatkan kemampuan literasi digitalnya. Kemampuan literasi digital yang harus dimiliki guru salah satunya dengan cara mengembangkan bahan ajar pembelajaran online yang sesuai dengan tujuan pembelajaran. Lebih khusus pada guru matematika, harus dapat menggunakan teknologi yang menunjang dalam membuat bahan ajar karena matematika tidak lepas dari penggunaan simbol, menggambar grafik, diagram, bangun datar, dan lain sebagainya. Pendampingan penguasaan aplikasi fx-draw diharapkan dapat meningkatkan kemampuan guru dalam mengembangkan bahan ajar matematika sehingga dapat digunakan pada pembelajaran online. Kegiatan pengabdian ini dilaksanakan melalui empat tahapan yaitu observasi awal pada sekolah mitra yaitu SMP Muhammadiyah 6 Dau dan SMP Diponegoro Batu, perencanaan, pelaksanaan pelatihan aplikasi fx-draw dan implementasi pengguanannya dalam mengembangkan bahan ajar, dan refleksi evaluasi kegiatan. Kegiatan ini terlaksana dengan baik yang dibuktikan dengan penguasaan guru dalam mengoperasikan aplikasi fx-draw sehingga menghasilkan bahan ajar berupa Lembar Kegiatan Peserta Didik (LKPD) dan angket refleksi evaluasi mendapatkan respon positif dari guru sekolah mitra peserta pelatihan.
