Abstract

This study aims to analyze and determine: (1) the level of students' mathematical creative thinking ability when taught using the Contextual Teaching and Learning (CTL) model; (2) a description of the students' creative thinking process in mathematics during the learning process using the Contextual Teaching and Learning (CTL) model. This research is a descriptive qualitative study. The subjects of this research were 30 students of class VIII-2 from SMP Negeri 1 Pematangsiantar. The research findings are as follows: (1) 18 students in the high-ability category were classified as highly creative, fulfilling 3 indicators of creative thinking: fluency, flexibility, and novelty; 9 students in the moderate-ability category were classified as creative, fulfilling 2 indicators of creative thinking: fluency and flexibility; and 3 students in the low-ability category were classified as less creative, fulfilling only 1 indicator of creative thinking: fluency. These results indicate that students demonstrated an improvement in creative thinking abilities after being taught using the Contextual Teaching and Learning (CTL) model. It is also hoped that the Contextual Teaching and Learning model can be applied in the learning process to enhance students' mathematical creative thinking abilities.: Answering Process; Contextual Teaching and Learning; Creative Thinking.

Abstract

Computational thinking abilities assist students in solving complex problems, enhancing productivity, and preparing them to face challenges in various fields. The problem-based learning (PBL) model was chosen because it is believed to improve students' computational thinking skills, as well as their critical and creative thinking abilities, which are often difficult to achieve through conventional learning. This research aims to determine the differences in students' computational thinking abilities through the application of problem-based learning and traditional learning methods. The research method was an experiment involving a population of all 2020 Mathematics Education students who took six linear program courses at Medan State University. Sampling was conducted using a random sampling technique, focusing on the PSPM 20B and PSPM 20C classes, totaling 60 students. This study employed a pretest-posttest control group design. Results from previous research indicated that the average computational thinking ability of students in the experimental class was higher than that of the control class, with scores of 82.67 for the experimental class and 69.00 for the control class. From the results of the average difference test, it can be concluded that there is a significant difference in the computational thinking abilities of students taught using the problem-based learning model compared to those taught using the traditional learning model, with PBL being more effective.

Abstract

Specifically, it examines (1) the feasibility of using these digital books and (2) their practicality digital books in a real classroom setting. The research follows Plomp's development model, which includes three stages: initial investigation, development or prototyping, and assessment. The study focuses on class X students at SMK Taman Siswa Binjai. To gather data, questionnaires were distributed to media and material experts to evaluate the feasibility of the digital book learning media. Additionally, student response questionnaires were used to assess the practicality of these digital books. The data analysis examined the validity and practicality of the digital book learning media created with Flip PDF Corporate, based on digital literacy. The findings reveal that the developed digital book learning media is highly feasible, with an impressive feasibility score of 98%. Moreover, the practicality assessment showed that students found the digital book products very practical, with a high approval rating of 94.72%. Future research should consider conducting longitudinal studies to evaluate the long-term effects of using digital book learning media on students' knowledge retention, critical thinking skills, and motivation. This research provides valuable insights into the sustainability and effectiveness of digital learning media.
