Abstract

In this modern era, it is important for teachers to use Android as a learning medium. This aims to facilitate the learning process. The purpose of this study was to test the validity, practicality, and effectiveness of Android-assisted learning media to improve junior high school students' thinking skills. This study used the ADDIE model with 30 students of Rengat 1 Public Middle School as research subjects. The instruments used are non-test instruments in the form of validation sheets and practicality sheets. For data collection techniques, namely by taking validation data, practicality data and effectiveness to students. The data analysis technique used is to conduct product validation tests on experts, practicality and effectiveness tests on students. From the research results, it was found that the media was already in very valid results with a percentage of 88.25%, and for practical results a percentage of 80.26% was obtained with a very practical category. The effectiveness results showed that the pretest results of students who achieved KKM were only 20%, and the posttest of students who achieved KKM increased by 80%. This makes the learning media ready to be used by the teacher to students in the classroom.

Abstract

NOTICE OF ARTICLE RETRACTION Dear Readers and Stakeholders,We hereby announce that the article titled "Mapping Research Trends of TikTok in Education: A Bibliometric Analysis", published in IJIE (Indonesian Journal of Informatics Education), Volume 8, Issue 2 (December 2024), has been officially retracted from publication.Reason for Retraction:Following a thorough internal investigation, it was discovered that a violation of publication ethics was committed by the corresponding author. Specifically, the violation involved the addition of author names by editing the article metadata after the article had been accepted for publication. This act is deemed an exploitation of the publishing system by including authors whose contributions could not be clearly verified in the preparation of the article.This behaviour violates the principles of transparency, academic integrity, and the ethical publishing guidelines established by IJIE (Indonesian Journal of Informatics Education), as well as the standards set forth by the Committee on Publication Ethics (COPE).Further Actions:The article has been officially retracted and will be clearly marked as such on our publication platform.Information regarding this retraction will remain accessible to ensure transparency and accountability within the academic community.Further steps will be taken in accordance with our publication ethics policies.We reaffirm our commitment to upholding the highest standards of academic integrity and quality in scientific publishing. We sincerely apologise to our readers, contributing authors, and the wider scholarly community for any inconvenience caused by this matter.Thank you for your understanding and continued support. Yours sincerely,Editor-in-ChiefAbstract:This study aims to identify research trends related to the use of TikTok in the field of education using bibliometric analysis. Data was obtained from 46 publications obtained from the Scopus database in 2020–2023, which were filtered based on TikTok keywords in the context of education. Data analysis was carried out with the biblioshiny package of the RStudio application. The results showed that publications increased sharply in 2022. Geographically, China and the United States contributed the most. The main keywords included "social networking", "TikTok", and "students" representing the research trends on utilising TikTok for learning. The most cited articles indicate TikTok's potential as an innovative pedagogical tool to increase learners’ engagement and motivation and expand public access to education and health information. Further research was recommended to enrich multidisciplinary perspectives and maximise the benefits of TikTok for learning.

Abstract

This study is developmental research that aims to develop a numeracy literacy instrument based on computational thinking in mathematics learning, using the Plomp model to ensure the quality and relevance of the instrument. Selection of respondents using Cluster Random Sampling involving 220 grade 8 students at 5 State Junior High Schools in Bantul Yogyakarta, the instrument was tested for content validity using the Aiken method, resulting in an average validity score of 0.81, indicating that the instrument is valid. Confirmatory Factor Analysis (CFA) results showed that all latent variables had loading factor values above 0.5, these items more accurately represent numerical literacy abilities based on the computational thinking being measured.. Construct Reliability (CR) and Average Variance Extracted (AVE) analysis show that all dimensions meet the criteria, although the Problem Decomposition dimension requires more attention to its indicators because its AVE value is only slightly above the minimum limit. This study is limited to a relatively small number of respondents, so it is necessary to expand the sample coverage to increase the generalizability of the results. This research develops an effective instrument to improve mathematics learning and prepare students for final exams such as the Asesmen Standardisasi Pendidikan Daerah (ASPD) with better numeracy literacy skills.

Abstract

This study investigates the influence of principal leadership, infrastructure utilization, and administrative services on school effectiveness in public junior high schools in Tual City. Effective school management is essential for improving educational outcomes, particularly in regions where resources and leadership play a critical role in performance. The research involved 133 teachers and 318 students, selected through appropriate sampling techniques. Data were collected using a structured questionnaire covering four key variables: principal leadership, infrastructure use, administrative services, and school effectiveness. Data analysis was conducted using SPSS version 25, employing tests for normality, linearity, multicollinearity, and heteroscedasticity to ensure statistical validity. Findings revealed that principal leadership, infrastructure use, and administrative services were rated in the high category, with more than 86% of both teacher and student responses reflecting positive perceptions. Regression analysis showed a positive and significant combined effect of these three variables on school effectiveness, with results for teacher responses (F = 5.122, sig. = 0.00) and student responses (F = 32.334, sig. = 0.00) indicating strong statistical significance. These results emphasize the crucial role of leadership quality, efficient use of infrastructure, and strong administrative support in enhancing school effectiveness. The study underscores the need for targeted efforts in strengthening these areas to improve the overall quality of education in Tual City's junior high schools.
