Abstract

This research aims to describe the problem of cheating in reducing similarity using Turnitin software in writing scientific articles, as well as the factors causing cheating problems carried out by students. The research method used is qualitative with a case study approach. Data collection techniques include observation, documentation, and interviews with students taking the scientific paper course. The sample consists of students taking the scientific paper course with focus on research mathematics in Open University, Study Program X, using purposive sampling technique. The research findings indicate, there are cheating techniques used to reduce similarity that are undetectable by Turnitin: (1) adjusting spaces in a text that is too large or too small, (2) converting text files into images, (3) adding specific letters to the manuscript, (4) inserting specific small-sized numbers that are almost invisible, (5) intentionally making typing errors, and (6) adding specific symbols to the scientific article manuscript.

Abstract

This study aims to investigate the improvement of students' understanding of mathematical concepts in class VII C of SMP Muhammadiyah 8 Yogyakarta by implementing the Contextual Teaching and Learning (CTL) model with the assistance of mind mapping media. The method applied is Classroom Action Research consisting of two cycles, each cycle involving four stages: planning, implementation, observation, and reflection. The research subjects are 28 students from class VII C of SMP Muhammadiyah 8 Yogyakarta. The results of the study indicate that the application of CTL with mind mapping is effective in enhancing students' understanding of mathematical concepts. This is evidenced by the average scores increasing from 51.80 in the pre-cycle, to 59.50 in Cycle I, and reaching 85.80 in Cycle II. Improvement is also observed in the percentage of understanding mathematical concepts in each indicator, rising from 50.19% in the pre-cycle to 82.88% at the end of Cycle II. This demonstrates the effectiveness of the CTL model with mind mapping in enhancing students' mathematical comprehension.
