The present study examines whether school bullying moderates gender differences in outcomes on the TIMSS mathematics test among fourth-grade students in Bosnia and Herzegovina. The sample consisted of 3,324 fourth-grade students (1,654 girls and 1,670 boys). Mathematics achievement was assessed using TIMSS plausible values, and analyses accounted for the complex survey design using the student sampling weights. Results showed a significant negative association between school bullying and mathematics achievement for both genders, as well as a significant gender × bullying interaction. Boys achieved higher scores at low and moderate levels of bullying, whereas girls outperformed boys under high bullying exposure. This pattern was consistent across all plausible mathematics values. The results suggest that efforts aimed at improving school social climate and reducing bullying may play an important role in promoting both students’ academic achievement and their well-being. </style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">157-167</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Yoon Fah Lay</style></author><author><style face="normal" font="default" size="100%">Khar Thoe Ng</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">CORRELATES OF SCIENCE CLASSROOM TEACHING WITH SOUTHEAST ASIAN AND EAST ASIAN EIGHTH GRADERS’ SCIENCE ACHIEVEMENT IN TIMSS 2015 </style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">classroom teachings</style></keyword><keyword><style  face="normal" font="default" size="100%">comparative study</style></keyword><keyword><style  face="normal" font="default" size="100%">science achievement</style></keyword><keyword><style  face="normal" font="default" size="100%">TIMSS</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2021</style></year><pub-dates><date><style  face="normal" font="default" size="100%">June/2021</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2021/457-1623676864.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">79</style></volume><pages><style face="normal" font="default" size="100%">Continuous</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Trends in International Mathematics and Science Study (TIMSS) is an international comparative study that has been implemented by the International Association for the Evaluation of Educational Achievement (IEA) since 1995. This proposed study is aimed to identify the correlations of science classroom teachings with eighth graders' science achievement in TIMSS among Southeast Asian and East Asian countries. The freely downloadable secondary data were analyzed using IEA's International Database (IDB) Analyzer (version 4.0) for TIMSS, a plug-in for SPSS. TIMSS uses an imputation methodology, involving plausible values, to report student performance. This study found that countries with higher average science achievement allocated higher percentage of educational hours for science teaching, students were taught the TIMSS science topics, students attended schools with science laboratories and have assistance available when conducting experiments, computer availability during science lessons, with science teachings were not limited by student needs, and less frequency of student absences. Based on the research findings, policy recommendations were made to the Malaysian Ministry of Education to boost Malaysian eighth graders' science performance in the forthcoming TIMSS assessments. </style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><work-type><style face="normal" font="default" size="100%">Original article</style></work-type><section><style face="normal" font="default" size="100%">425-450</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Yoon Fah Lay</style></author><author><style face="normal" font="default" size="100%">Murugan Rajoo</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">AFFECTIVE FACTORS CONTRIBUTING TO SOUTHEAST ASIAN AND EAST ASIAN EIGHTH GRADERS’ SCIENCE ACHIEVEMENT IN TIMSS 2015</style></title><secondary-title><style face="normal" font="default" size="100%">Problems of Education in the 21st Century</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">affective factors</style></keyword><keyword><style  face="normal" font="default" size="100%">comparative study</style></keyword><keyword><style  face="normal" font="default" size="100%">science achievement</style></keyword><keyword><style  face="normal" font="default" size="100%">TIMSS</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2020</style></year><pub-dates><date><style  face="normal" font="default" size="100%">December/2020</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://oaji.net/articles/2021/457-1612880930.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">78</style></volume><pages><style face="normal" font="default" size="100%">Continuous</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Trends in International Mathematics and Science Study (TIMSS) is an international comparative study that has been implemented by the International Association for the Evaluation of Educational Achievement (IEA) since 1995.

The freely-downloadable secondary data were analyzed using IEA's International Database (IDB) Analyzer (version 4.0) for TIMSS, a plug-in for SPSS. TIMSS uses an imputation methodology, involving plausible values, to report student performance. This study found that students' views on engaging teaching in science (BSBGESL) were negatively and significantly contributed to eighth-grade students' science achievement in Thailand, Singapore, Chinese Taipei, and Hong Kong SAR. Students Like Learning Science (BSBGSLS) were positively and significantly contributed to eighth-grade students' science achievement in Malaysia, Singapore, Thailand, Hong Kong SAR, and Chinese Taipei. Students Confident in Science (BSBGSCS) were positively and significantly contributed to eighth-grade students' science achievement in Korea, Japan, Chinese Taipei, Hong Kong, Thailand, and Singapore. Students Value Science (BSBGSVS) was positively and significantly contributed to eighth-grade students' science achievement in Japan, Korea, Thailand, Chinese Taipei, Singapore, and Malaysia.
