Abstract

This research is based on the problem of low mathematical reasoning ability of high school students. This study aims to examine the improvement of mathematical reasoning ability among students who get Differentiated Instruction approach and conventional learning. The research design was quasi experiment with non-equivalent control group research design using Purposive Sampling technique. Instruments used include mathematical prior knowledge test, mathematical reasoning tests, observation sheets, and interview guides. Quantitative analysis was performed by using t-test and two-way anova test. The result of the research shows that (1) the improvement of student’s mathematical reasoning ability through DI learning is better than conventional learning, (2) The improvement of student’s mathematical reasoning ability through DI learning is better than the students who follow the conventional learning in terms of Mathematical Prior Knowledge. Keywords: Differentiated Instruction, Mathematical Prior Knowledge, Mathematical Reasoning.

Abstract

This study aims to determine how students critical thinking ability who study with probing-prompting and conventional learning models are. This research is a quantitatif research with a quasi-experimental design group. The research population was all students of class X SMK Setih Setio 2 Muara Bungo, Jambi. The research sample consisted of two classes with a sample size of 62 people determined by simple random sampling, namely X MM as the control class using the conventional learning model and X AK as the experimental class using the Probing-Prompting learning model. Requirements analysis test has been carried out so that the data obtained are not normally distributed and not homogeneous. The hypotheses were analyzed using the U-Mann Whitney test at a significant level of α=0,05. Based on data analysis and hypothesis testing, it was found that: (1) there were differences in students' critical thinking skills taught using probing-prompting and conventional learning models, and (2) there is an increase in students' critical thinking skills taught by using probing-prompting and conventional models.

Abstract

There is a decrease in mathematics learning achievement and teachers have difficulty in determining appropriate learning models and strategies in the online learning process. Therefore, this study aims to identify the comparison of mathematical abilities based on an interactive learning model setting cooperative, expository, and problem-based learning. This research is a quantitative research with a quasi-experimental type conducted in one of the high schools in Jakarta. The inferential analysis technique is divided into two, namely the normality test using the Chi-Square test and the homogeneity test using the Levene test in the SPSS calculation program. The hypothesis test used by the researcher used the one-way ANOVA test because it used 3 variables and the data used were normally distributed and homogeneous. Furthermore, the researchers continued the paired hypothesis test t test. The results of the t-test resulted in a cooperative setting interactive learning model with expository learning and problem-based learning models having a significant difference in average mathematical ability. Cooperative setting interactive learning with problem-based learning model has a significant difference in average mathematical ability. Meanwhile, expository and problem-based learning model does not have a significant difference in average mathematical ability.

Abstract

Kondisi permasalahan yang dihadapi dalam pengabdian ini antara lain guru kesulitan dalam mencari dan menentukan sumber belajar yang cocok. Meskipun sumber belajar yang variatif tersedia, tidak semua guru memiliki pemahaman dan keterampilan yang cukup untuk memanfaatkannya secara efektif. Guru masih kurang akrab dengan teknologi atau kurang paham tentang cara mengintegrasikan sumber belajar tersebut ke dalam pembelajaran. Tidak semua sumber belajar yang tersedia memiliki kualitas yang sama, sumber belajar yang tersedia di internet mungkin saja tidak relevan atau tidak sesuai dengan tujuan pembelajaran yang akan dicapai. Oleh karena itu diperlukan pelatihan tentang pemanfaatan sumber belajar yang variatif bagi guru. Maka dalam hal ini, tim melakukan sharing knowledge bagi guru dan pembelajaran kepada siswa. Diskusi mencakup prinsip pembelajaran era zaman now, pembelajaran berbasis budaya, menggunakan edmodo dan kahoot. Melalui pelatihan dan pembelajaran yang dilakukan diperoleh bahwa: 1) Siswa menerima pembelajaran matematika yang menyenangkan; 2) Guru-guru mendapat penambahan ilmu dan wawasan baru mengenai penerapan IT dalam pembelajaran dan bagaimana tetap menekankan pemahaman konsep dengan memanfaatkan benda-benda sekitar siswa/i tersebut; 3) Guru-guru juga bisa menerapkan penggunaan pembelajaran online dengan menggunakan Edmodo dan Kahoot.

Abstract

This study aims to analyze the difficulties faced by students when solving algebraic operation problems based on the criteria of problem solving ability. This study was conducted to understand the factors that master students' difficulties in solving algebraic problems. This research used descriptive method with qualitative approach. The research subjects consisted of 35 students of class VII-G at SMP N 8 Tambun Selatan. Data were collected through observation, tests, questionnaires, and documentation. Data analysis used the Miles and Huberman data analysis model. Data validity was checked through method tringulation. The results showed that of the 35 students studied: 1) 61% of students had difficulty in understanding the problem, 2) 57% of students had difficulty in planning the solution, 3) 73% of students had difficulty in carrying out the plan, and 4) 86% of students had difficulty in checking back. The main factors that influence these difficulties are students' understanding of basic algebraic concepts, difficulties in applying mathematical concepts to the algebraic context and underdeveloped problem solving skills. In understanding math problems and formulating the steps needed to solve them, students often face difficulties.

Abstract

The demand of the Indonesian society to own homes and properties is increasing along with the growth of Indonesia's population. This has led to an increase in population density, causing property prices to rise. The way to own property or a house in accordance with monthly income is by using bank housing loans. Three Indonesian banks renowned for housing loan applications, namely BTN, Mandiri, and BSI, were selected as samples in this study. These three banks have their own advantages and different bank interest rates. Therefore, this research was created as a tool for consumers to make decisions by considering the advantages obtained when applying for a loan at one of the three banks. This study employs the Newton's interpolation method to generate formulas that can help solve consumer problems. The results of this study generally indicate that Mandiri bank has an advantage in terms of lower installment costs compared to BTN and BSI.
