Abstract

A learning process is said to be good if learning is student-centered. Students perform activities in the learning process by using context as a starting point in learning. Design Research with a cycle that contains components of knowledge (K), design (D), experiment (E), reflection (R) is an alternative to create student-centered learning and obtain information and findings in research. This research was conducted in one of the junior high schools in Palembang City with a sample of 23 students. Research procedures were carried out including observation data analysis, interviews and documentation analysis. The conclusion of this research is that the existing knowledge of students is used as a basis for designing learning activities so that when implementing experiments students are able to carry out activities that are related to the initial abilities of students so that the context appears to be a strating point in learning so that the findings that arise can be analyzed and become a reflection to carry out cycles. Then the effectiveness of learning goes according to design and produces a series of understanding of numbers and also the situation of "pulling" and "stretching" in the kite game can be converted into "positive and "negative" symbols

Abstract

Abstrak Penelitian yang dilakukan oleh Solomon dan Rothblum (1984), diketahui bahwa 50% sampai 90% terjadi prokrastinasi akademik pada mahasiswa. Knaus (2002) menemukan bahwa 95% mahasiswa di AS dengan sengaja menunda mengerjakan atau menyelesaikan tugas, dan 70% mahasiswa tergolong sering melakukan prokrastinasi. Penelitian lain yang dilakukan oleh Kartadinata dan Tjundjing (Mayasari dkk., 2010) di sebuah Perguruan Tinggi di Surabaya menemukan bahwa 95% mahasiswa mengaku pernah melakukan prokrastinasi akademik. Banyak faktor yang menyebabkan terjadinya prokrastinasi akademik, diantaranya yaitu kontrol diri dan konformitas. Penelitian ini bertujuan untuk mengetahui hubungan antara kontrol diri dengan prokrastinasi akademik serta mengetahui hubungan antara konformitas dengan prokrastinasi akademik pada mahasiswa program studi psikologi Universitas Negeri Surabaya. Penelitian ini menggunakan metode kuantitatif korelasional dengan sampel sebanyak 194 mahasiswa. Teknik analisis data yang digunakan adalah uji regresi logistik biner. Hasil dari penelitian ini menunjukkan bahwa kontrol diri memiliki hubungan yang signifikan dengan prokrastinasi akademik dengan nilai signifikansi sebesar 0,000, maka hipotesis pertama diterima, kontrol diri memiliki hubungan yang signifikan dengan prokrastinasi akademik. Hasil penelitian juga menunjukkan bahwa konformitas tidak memiliki hubungan yang signifikan dengan prokrastinasi akademik dengan nilai signifikansi 0,087, maka hipotesis kedua ditolak, yaitu konformitas tidak memiliki hubungan yang signifikan dengan prokrastinasi akademik. Nilai Negelkerke R Square sebesar 0,485 mengartikan bahwa variabel prokrastinasi akademik dipengaruhi oleh variabel kontrol diri sebesar 48,5%, sisanya 51,5% disebabkan oleh variabel lainnya yang tidak diteliti dalam penelitian ini. Kata Kunci: Kontrol Diri, Konformitas, Prokrastinasi Akademik, Mahasiswa Abstract Research conducted by Solomon and Rothblum (1984), it is known that 50% to 90% occurred academic procrastination on students. Knaus (2002) found that 95% of students in the U.S. with deliberately delaying the work or complete the task, and 70% of students classified as frequent procrastination. Another study conducted by Kartadinata and Tjundjing (Mayasari et al., 2010) at one of university in Surabaya found that 95% of students admitted to having academic procrastination. Many factors contribute to the academic procrastination, among which self-control and conformity. This study aims to determine the relationship between self-control and academic procrastination and determine the relationship between conformity and academic procrastination on students of psychology Universitas Negeri Surabaya. This study used a quantitative correlation with a sample of 194 students. The analysis technique used was a binary logistic regression. The results of this study indicated that self-control has a significant relationship with academic procrastination with a significance value of 0,000, the first hypothesis is accepted, self-control has a significant relationship with academic procrastination. The results also showed that conformity does not have a significant relationship with academic procrastination with a significance value of 0,087, the second hypothesis is rejected, conformity does not have a significant relationship with academic procrastination. Negelkerke R Square value of academic procrastination is 0,485 means that the variable was affected by self-control variable by 48.5%, the remaining 51.5% were caused by other variables not examined in this study.

Abstract

The use of gadgets in elementary school children is alarming. Prolonged use can lead to negative things for the growth and development of elementary school children. This service aims to realize the golden generation in 2045 by providing education to elementary school children about the impact of gadget use. There are 3 main focuses of the training that will be carried out, namely: Understanding and definition of gadget use, positive and negative impacts of gadget use, and minimizing gadget use. These three main activities are important activities that are followed by elementary school children. The results showed that the students were very enthusiastic and eager to participate in this educational activity. They actively asked questions and discussed the impact of gadgets. Students in this class showed commitment to apply the tips and strategies taught in the educational activities. They promised to reduce their gaming time, choose positive content, and interact more with friends and family. The education program also received a positive response from the school principal and teachers. The headmaster gave high appreciation for the initiative of the academician students in conducting this education. collaboration between the academician and the school is needed in order to realize the sustainability of the program that has been implemented.

Abstract

Probabilistic reasoning is a fundamental competency in high school mathematics education, yet the comparative strengths and limitations of empirical (frequency-based, real-world data) versus classical (a priori, theoretical) probabilistic reasoning approaches remain understudied in the Indonesian secondary school context. This Systematic Literature Review (SLR) synthesises 25 peer-reviewed studies published from 2021 to 2025, supplemented by four methodological anchor studies (2012–2024), identified through a PRISMA 2020-compliant search of Scopus, ERIC, Google Scholar, and SINTA databases. Studies were screened against predefined inclusion/exclusion criteria and assessed for quality using the Mixed Methods Appraisal Tool (MMAT). Findings indicate that empirical reasoning significantly outperforms classical reasoning in probabilistic literacy and critical reading of statistical information from media sources (66.7% vs. approximately 15%), while classical reasoning is superior in procedural accuracy and conceptual depth, particularly in applying Bayes' theorem (58% vs. 10.6%). The transposed conditional bias affects more than 50% of participants in empirical contexts, while the equiprobability fallacy is more prevalent in classical settings. Both approaches yield comparable proportions of students reaching the reflective use metacognitive level (approximately 36%), but through distinct cognitive pathways. Integration of both approaches within non-routine problem-based learning environments is recommended to develop holistic probabilistic competency in high school studens
