Implementing of the Aptitude Treatment Interaction (ATI) Learning Model for Linear Equation Systems and Matrix Materials for Prospective Mathematics Education Teacher Students

Tue, 30 Jan 2024 00:00:00 +0000

ABSTRACT

This study aims to see the learning outcomes of prospective mathematics education teacher students after applying the Aptitude Treatment Interaction (ATI) learning model for linear equation systems and matrix. This study uses a quantitative descriptive approach with data collection techniques are test and documentation. Subjects were grouped into three categories, namely subjects with high mathematical abulity, medium, and low mathematical ability. The results showed that the application of the Aptitude Treatment Interaction (ATI) learning model gave a good response to learning outcomes with an average of 78.10 in the good category. This can be seen from the student learning outcomes as a whole, both students with high mathematical ability, medium, and low mathematical ability. So, it can be concluded after applying the Aptitude Treatment Interaction (ATI) learning model that the overall intake of students when viewed from their mathematical abilities does not cause a wide gap between them.

Eduardus Beo Seso Delvion, Cecilia Novianti Salsinha, Minanur Rohman (Author) — Tue, 30 Jan 2024 00:00:00 +0000

The problems that occur in analyzing survival models based on parametric distributions require parameter values obtained from estimators. This study aims to obtain an estimator model of the lognormal distribution which has parameters and . Therefore, the maximum likelihood method approach is used to obtain the estimators and . However, the problem encountered is that the maximum likelihood model of the lognormal distribution for Type II cencoring data produces quite complex equations, so an approach with a Taylor series is needed only for the first order. The results obtained are estimators and which can be applied to Type II cencoring data based on a lognormal distribution.

Rahma Dani Ilham, Fazri Zuzano, Listy Vermana (Author) — Tue, 30 Jan 2024 00:00:00 +0000

This research was motivated by students lacking enthusiasm and being less active in learning mathematics. One effort to overcome this problem is to develop problem based learning worksheets because they can help teachers in developing student centered learning which makes students active in learning. This type of research is development using the ADDIE development model which has 5 stages, namely analysis, design, development, implementation and evaluation. Product trials were carried out at SMP N 1 Kuantan Hilir. The research subjects were 10 students in class VIII.2. The research results showed that problem based learning worksheets were valid by two validators. Worksheets based on problem based learning were declared practical with a score of 63%. So that problem based learning worksheets are valid and practical. From the research, it is recommended that teachers use LKS based on problem based learning as teaching materials and several shortcomings during the research include: (1) in groups of students only a few people are looking for answers and apart from that they only see answers from their group friends (2) students tended to tell stories during learning (3) the researcher did not take all the subjects in the class (4) when filling in the practicality sheet the students were not honest.

The penetrating waterbird on the east coast of North Sumatra is Egretta Garzetta. It is a kind of water bird that lives in water or parts of wetlands. The presence of waterbirds is an important indicator to evaluate the environmental quality and productivity of wetlands. Bird distribution patterns are needed to overcome problems related to habitat, such as food availability and population size. This study aims to apply themethod Nearest Neigbord Analysis to the distribution pattern of Egretta Garzetta in the Mangrove area of North Sumatra. This study uses a quantitative approach to the type of applied research (Applied Research). The type of data used in this research is secondary data. Analysis of the data in this study using Nearest Neighbor Analysis. The pattern of the spread of Egretta Garzetta in the Mangrove areas in North Sumatra have clumped pattern (clustered).The results from Nearest Neighbor Analysis show that the index value of the clustered distribution pattern can be caused by the abundance of food sources in a habitat.

Rahaju Rahaju, Dias Wahyulina, Riski Nur Istiqomah Dinullah (Author) — Tue, 30 Jan 2024 00:00:00 +0000

Negative perceptions of mathematics cause students to be lazy, uninterested and even refuse to study mathematics, resulting in low student achievement. The aim of this research is to describe the steps for learning pair check with the help of question cards to improve learning achievement in circle material. This research is classroom action research. The research subjects were 30 class VIII students at SMPN 2 Turen. Data collection uses observation, documentation and test techniques. The research instruments used observation. Sheets, field notes, photo and video documents, and test. The research results show that pair check learning begins by assigning students to study reading material individually, then solve problems in groups of 4 students. Next, give question cards to be completed in small groups (2 students). In small groups, students take turns playing the role of partner and coach in solving the questions card. Discussion of question answers is carried out classically through presentation activities. Student learning achievement using the pair check model assisted by question cards has increased. In cycle 1, 70% of students had completed their studies. The results of this research are expected to provide alternative stages and learning media that can improve student learning achievement.

Febi Sanjaya (Author) — Tue, 30 Jan 2024 05:47:42 +0000

Mata kuliah Pengantar Analisis Real termasuk mata kuliah yang tidak favorit di prodi Pendidikan Matematika Universitas Sanata Dharma. Salah satu alasannya adalah karena mata kuliah ini penuh dengan pembuktian dan abstrak. Berdasarkan pengalaman peneliti, selama mengajar mata kuliah ini mahasiswa kesulitan dalam memahami proses-proses pembuktian terkait sistem bilangan real. Penelitian ini bertujuan untuk mengetahui kemampuan mahasiswa dalam mengonstruksi pembuktian pada mata kuliah Pengantar Analisis Real. Penelitian ini menggunakan metode deskriptif kualitatif, dengan menggunakan instrumen berupa 3 soal essay untuk mengetahui kemampuan mahasiswa dalam mengkonstruksi pembuktian. Subyek dari penelitian ini adalah 31 mahasiswa Pendidikan Matematika Universitas Sanata Dharma, yang sedang menempuh mata kuliah Pengantar Analisis Real. Hasil penelitian ini adalah 74% mahasiswa sudah mampu mengonstruksi bukti dengan benar untuk permasalahan sederhana (permasalahan 1), tetapi kurang dari 30% mahasiswa yang mampu mengonstruksi bukti dengan benar untuk permasalahan yang lebih kompleks (permasalahan 2 dan 3).
