Abstract

This study focuses on analyzing the application of differential equations in modeling the population growth of Kediri City through a logistic growth model, and aims to predict the city's population for the years 2021-2030. Employing a literature study approach, this research utilizes secondary data sourced from the official website of the BPS (Central Statistics Agency) of Kediri City. The data encompasses population figures from 2005 to 2020. To ensure the accuracy of the population predictions made by the logistic growth model, a comparison with the official data from the Central Statistics Agency is necessary. A critical aspect of this research involves estimating the carrying capacity of Kediri City's population, which is identified as 295,672 individuals in the year 2030. The findings indicate a significant growth trend in the population, characterized by a specific growth rate. To validate the accuracy of the logistic growth model, the Mean Absolute Percentage Error (MAPE) method was applied, resulting in an error percentage that falls within the highly accurate category, thus affirming the reliability of the model in predicting population growth trends.

Abstract

Differences in personality types significantly influence learning processes and outcomes, including problem-solving skills. This research aims to describe numeracy problem-solving skills among eleventh-grade students in the science group, focusing on the DISC personality types. The study, conducted in Kediri, West Java, Indonesia, involves two representatives for each personality type. The research utilizes the DISC personality test by William Moulton Marston, a numeracy problem-solving assessment consisting of three problems, and an interview guideline. Data accuracy is ensured through source and technique triangulation, along with member-checking to validate interview results. The findings reveal that students with dominance personality types generally follow a four-step numeracy problem-solving process, occasionally skipping the re-checking step for specific questions. Influence personality types also exhibit a four-step approach to numeracy problem-solving. In contrast, students with steadiness personalities accurately describe four levels of problem-solving to achieve correct results. Compliance personality types, while adhering to a four-step process, encounter inaccuracies in certain problem solutions. In summary, students with different personality types consistently undergo a four-step numeracy problem-solving process, but variations arise in the final outcomes of problem-solving.

Abstract

Kemampuan berpikir komputasi merupakan salah satu kemampuan yang harus dimiliki siswa pada abad 21. Penelitian ini bertujuan untuk mengetahui keefektifan metode scaffolding dalam meningkatkan kemampuan berpikir komputasi siswa SMP pada materi perbandingan. Pemilihan sampel menggunakan teknik sampling jenuh, di mana seluruh anggota populasi menjadi sampel penelitian. Jenis penelitian yang digunakan adalah quasi experiment dengan desain two group pre test post test. Pada kelas kontrol diberi perlakuan metode diskusi tanpa bantuan guru dan kelas eksperimen diberi perlakuan scaffolding. Data kemampuan berpikir komputasi siswa dikumpulkan menggunakan tes uraian yang memuat indikator berpikir komputasi (dekomposisi, abstraksi, algoritma, dan pengenalan pola). Data dianalisis menggunakan uji komparasi dan uji efektifitas. Berdasarkan hasil analisis data diperoleh bahwa pada kelas kontrol dan kelas eksperimen terdapat perbedaan kemampuan berpikir komputasi sebelum dan sesudah diberi perlakuan. Uji efektifitas dilakukan menggunakan N-Gain dengan kategori Hake (1999). Nilai mean N-Gain prosen pada kelas kontrol sebesar , artinya metode tidak efektif. Pada kelas eksperimen adalah 0,58 , artinya metode cukup efektif. Nilai sumbangan efektivitas berdasarkan rumus dan kriteria Cohen’s d (2007) diperoleh pada kelas kontrol adalah 1,146 yang berarti memberi efek sedang dan pada kelas eksperimen adalah , yaitu berpengaruh kuat dalam meningkatkan kemampuan berpikir komputasi siswa.

Abstract

Mathematization competencies among prospective teachers, focusing on their ability to construct and communicate mathematical arguments, are crucial for effective mathematics education. This exploratory study aimed to produce qualitative-descriptive data on prospective teachers' competencies of mathematization in teacher education programs. The study employs word problems based on everyday-life problems that are solved by the mathematization process and assessed based on three indicators of mathematization competencies. The data were collected from three groups of prospective teachers in the first, third, and fifth semesters, respectively, in the mathematics education study program at a public University in Kediri, Indonesia. The findings revealed that while all prospective teachers demonstrated basic skills in identifying assumptions and organizing problems, fifth-year students exhibited better abilities in mathematical argumentation, particularly in generalizing mathematical problems. These advanced abilities included the formulation, analysis, and presentation of proficient mathematical arguments, indicating a deeper understanding and mastery of mathematization that developed progressively throughout their education. The results of this study underscore the importance of sustained and structured learning experiences in mathematics teacher education programs to foster higher-order mathematical competencies. This study enriches the mathematics education literature by illustrating the growth of argumentation skills in mathematization among prospective teachers, highlighting the need for educational curricula that emphasize these advanced skills.

Abstract

This research was conducted at MTs Sunan Muria Ploso with the aim of describing the application of realistic mathematics education material of row and arithmetic series. Some research said that, in schools, applies mathematical concepts directly which causes students to feel bored quickly and the methods used are less varied. In order for mathematics learning to be creative, interesting and fun, then one way is to apply the Realistic Mathematics Learning approach. This research is a descriptive qualitative research with 40 students of class VIII-D MTs Sunan Muria Ploso as the subjects. Data collection techniques using the method of documentation, and interviews conducted by researchers with students. Data collection techniques using the method of documentation and interviews conducted by researchers with students. The sampling technique used was purposive sampling. The data analysis technique in this research is qualitative data analysis, which consists of data reduction, data presentation, and drawing conclusions. The research instrument is a test and interview guide. The results showed that the arithmetic series material can be applied well with the RME approach. The conclusion of this study is that the Learning with Realistic Mathematics approach can support students in understanding and determining arithmetic series formulas, students use various symbols in implementing them so as to help students understand the concepts of arithmetic series.
