MATHEMATICS TEACHER’S SELF-EFFICACY OF TECHNOLOGY INTEGRATION AND TECHNOLOGICAL PEDAGOGICAL CONTENT KNOWLEDGE

This study conducted to determine the mathematics teacher’s self-efficacy of technology integration and Technological Pedagogical Content Knowledge (TPACK) based on gender and teaching experience. In this research, 66 mathematics teachers from national secondary schools were chosen as the samples to answer a survey questionnaire containing 71 items with a five-point Likert scale. Descriptive statistics, such as mean, percentage, and standard deviation, were employed to analyze the data. T-test was used to gauge the mathematics teacher’s self-efficacy of technology integration and TPACK based on gender, and one-way ANOVA was employed to determine mathematics teacher’s self-efficacy of technology integration and TPACK based on teaching experience. Besides, Pearson’s correlation coefficient was used to determine the relationship between the mathematics teacher’s self-efficacy of technology integration and TPACK. The findings showed no significant difference between genders and the teaching experience of the mathematics teacher’s self-efficacy and TPACK. However, mathematics teacher’s self-efficacy of technology integration and TPACK were strongly associated. In conclusion, whether male or female, for as long as mathematics teachers had been working, they have a positive self-efficacy in initiating technology integration and introducing TPACK. The implication was gender and teaching experience were not a critical factor for mathematics teacher’s self-efficacy of technology integration and TPACK. For future research related to this study, it could introduce other factors, such as academic qualification and technology courses they had attended

[The Early Unsung Scholars in Arabic Grammar (69-183h)] Sarjana Tatabahasa Arab Terawal yang Tidak Didendang (69-183h)

This article discusses the biographies of the earliest ancient Arabic grammar figures. Books related to the history of Arabic grammar often feature the earliest scholars of Arabic grammar such as Abu al-Aswad al-Du'ali (69-129H), 'Abdullah ibn Abi Ishaq (149-183H), al-Khalil ibn Ahmad al-Farahidi ( 100-170H) and Sibawayh (148-180H). While there are some of the names of the earliest scholars of Arabic grammar of the time that are almost unknown about their biographies, but their service to the development of Arabic grammar is great. This study focuses on the biographies of the earliest Arabic grammar scholars who lived between the years 69H to 183H. Data collection was done using al-Maktabah al-Shamilah software which involves digitally filtering 1,066 books. All data collected will be critically analyzed and analyzed. The procedure for analyzing content data is to identify the source of reference, secondly, critical research on information literacy; third, analysis and classification of information by category and fourth writing of study data. This study produces two research findings to coincide with the research problem. The findings of the study show that the isolation of information about some of these past figures is based on the scenario of writing past historical sources. The writing style of these sources focuses more on well-known figures than other figures. In addition, the findings of the study also show the lack of information for some of the Arabic grammar figures of the past. Based on the data and findings of the study shows the lack of information on this unspoken figure. It is hoped that more research on this isolated figure is done by other researchers. Differences in study results may be compared and used as a guide for future researchers Artikel ini membincangkan biografi tokoh tatabahasa Arab silam terawal yang kurang didendangkan. Buku-buku berkaitan sejarah tatabahasa Arab sering menonjolkan tokoh sarjana tatabahasa Arab terawal seperti Abu al-Aswad al-Du’ali (69-129H), ‘Abdullah ibn Abi Ishaq (149-183H), al-Khalil ibn Ahmad al-Farahidi (100-170H) dan Sibawayh (148-180H). Sedangkan di sana terdapat beberapa nama tokoh sarjana tatabahasa Arab terawal sezaman yang hampir tidak diketahui mengenai biografi mereka, namun jasa mereka terhadap perkembangan tatabahasa Arab adalah besar. Kajian ini memfokuskan biografi tokoh sarjana tatabahasa Arab terawal yang hidup di antara tahun 69H hingga 183H. Pengumpulan data dibuat dengan menggunakan software al-Maktabah al-Shamilah yang melibatkan penyaringan 1,066 buah buku secara digital. Kesemua data yang dikumpul akan diteliti dan dianalisis secara kritis. Tatacara menganalisis data kandungan adalah dengan mengenal pasti sumber rujukan, kedua, penelitian terhadap literasi maklumat secara kritis; ketiga, penganalisisan dan pengelasan maklumat mengikut kategori dan keempat penulisan data kajian. Kajian ini menghasilkan dua dapatan kajian bertepatan dengan permasalahan kajian. Dapatan kajian menunjukkan keterpencilan maklumat mengenai beberapa tokoh silam ini adalah berdasarkan senario penulisan sumber sejarah lepas. Corak penulisan sumber-sumber ini lebih banyak memfokuskan tokoh yang sedia terkenal berbanding tokoh-tokoh lain. Selain itu, dapatan kajian juga menunjukkan ketidakwujudan maklumat untuk beberapa tokoh tatabahasa Arab silam ini. Berdasarkan data dan dapatan kajian menunjukkan kepincangan maklumat terhadap tokoh yang tidak didendangkan ini. Diharapkan lebih banyak kajian mengenai tokoh terpencil ini dilakukan oleh pengkaji lain. Perbezaan hasil kajian mungkin dapat dibandingkan dan digunakan sebagai panduan untuk pengkaji akan datan
