The research involved 30 students from class VIII.1 as participants. Data collection was performed using observation and mathematical problem-solving tests. The findings revealed an improvement in students\u27 problem-solving abilities, with average scores increasing from 26.5 in the initial test to 52.33 in the first cycle and 65.5 in the second cycle. These results demonstrate that implementing the problem-based learning model effectively enhances both the learning process and students\u27 mathematical problem-solving skills at MTs PP Nurul Islam Kampung Baru
Development of ispring-assisted interactive learning media to support students self-regulated learning on flat-sided geometric solids
Full text linkThis research was motivated by the importance of fostering student independence in learning, particularly through the development of self-regulated learning, which does not emerge without external support. The aim of this study is to develop interactive learning media assisted by iSpring that meet the criteria of validity and practicality, in order to support students self-regulated learning and help eighth-grade junior high school/madrasah students understand the topic of flat-sided geometric solids. The development process follows the ADDIE model. The test subjects consisted of eighth-grade students at SMPN 20 Pekanbaru. Data were collected through interviews and questionnaires, using instruments such as expert validation sheets, student response questionnaires, and a self-regulated learning questionnaire. Validation results indicated that the media was classified as very valid with an average score of 3.76. In the small group trial, student responses yielded an average score of 0.92 (very practical), while the self-regulated learning score averaged 77.51% (good). In the large group trial, student responses had an average score of 0.81 (practical), and the self-regulated learning score was 79.61% (good). These results indicate that the developed learning media meets the criteria of being both valid and practical
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Pengembangan Media Pembelajaran Matematika Interaktif Berbasis Articulate Storyline untuk Memfasilitasi Kemandirian Belajar Siswa pada Materi Transformasi Geometri Kelas IX SMP/MTs
No full textThis research is a development research (R&D) with the aim of producing an interactive mathematics learning media based on Articulate Storyline that meets the valid and practical requirements to assist grade IX students of SMP/MTs in understanding geometry transformation material and facilitating student learning independence. This development research uses the Borg and Gall development model which consists of ten stages, but in this study only reached stage seven, namely: (1) potential and problems; (2) data collection; (3) product design; (4) design validation; (5) design revision; (6) product trial; and (7) product revision. Researchers explore potentials and problems through interviews, observations, questionnaires, and literature studies. Learning media and guidebooks were validated by three validators. The instrument used was a learning media validation questionnaire and a learning media guide book validation questionnaire. The average value of learning media validation is 3.37 with a very valid category and the average value of guide book validation is 3.52 with a very valid category. The learning media was tested on six students of class IX SMP, the instruments used were student response questionnaires and student learning independence questionnaires. The product trial result was 0.96 with a very practical category and very well facilitated student learning independence of 84.33%
Development of realistic mathematics education-based worksheets to facilitate mathematical connection abilities on pythagorean theorem material
Full text linkThis study aimed to develop a student worksheet on the Pythagorean Theorem utilizing the Realistic Mathematics Education (RME) approach, designed to meet validity and practicality standards to enhance the mathematical connection abilities of 8th-grade students. The research adopted the 4D development model, which includes the stages of Define, Design, Develop, and Disseminate. To ensure the validity of the student worksheet, three experts conducted a comprehensive validation process. Feasibility data were collected through trials involving 8th-grade students. The validation results indicated a score of 90.77%, categorized as "very valid." Small group trials yielded a practicality score of 89.98%, categorized as "very practical." Furthermore, large-scale trials demonstrated an average score of 89.29%, also categorized as "very practical." These findings highlight the effectiveness of the RME approach in facilitating students\u27 mathematical connection abilities through the Pythagorean Theorem material. The developed student worksheet was proven to be valid, practical, and highly beneficial for supporting the development of mathematical connections among 8th-grade students
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Full text linkThis research aims to develop a mathematics module based on Problem-Based Learning (PBL) for straight-line equation material, designed to enhance students\u27 mathematical problem-solving skills at SMP Negeri 1 Pasir Penyu. The study employed a Research and Development approach, utilizing a 4-D development model that includes the stages of Define, Design, Develop, and Disseminate. The subjects were eighth-grade students at SMP Negeri 1 Pasir Penyu. Data collection instruments included validation sheets to evaluate the module\u27s validity and student response questionnaires to assess its practicality. The module was tested in two phases: a small group trial and a large group trial. Results from the small group trial indicated that the module achieved an average score of 3.66, categorizing it as highly practical. Similarly, the large group trial yielded an average score of 3.57, also placing the module in the very practical category
