The aim of this research is to study the efficiency of the order-2 extrapolated implicit Runge-Kutta methods. The order-2 methods being considered are the implicit midpoint (IMR) and implicit trapezoidal (ITR) rules. These methods are applied with the polynomial and rational extrapolations actively and passively with smoothing to improve the accuracy. In order to reduce the round-off errors, a technique known as compensated summation with simplified Newton is implemented in all the numerical codes. The results are given based on numerical experiments that are carried out using MATLAB software. The findings showed that passive polynomial extrapolation by the IMR and ITR are more efficient than with active and passive rational extrapolation. The smoothing technique with extrapolation by the IMR and ITR gives better behavior than without the smoothing technique. It is therefore concluded that in solving chemistry, linear and nonlinear chemical and logistic curve problems, passive polynomi.....

The purpose of this study was to determine the effectiveness of an interactive geometry software program, Geometer’s Sketchpad (GSP), in the teaching and learning of mathematics among technical schools’ students. The quasi-experimental study was conducted on 56 students from a randomly selected technical school. The students were assigned into a controlled and an experimental group using cluster (class-based) random sampling. The control group received conventional teaching method while the experimental group was taught using a GSP module on a chosen topic namely Trigonometric Functions for the duration of 8 weeks. Three sets of tests, which are pre-test, post-test and retention-test were administered to both groups of students in weeks 1, 8 and 10, respectively. Besides the tests, a set of questionnaires and an interview protocol were used in collecting the empirical data. The results of tests and questionnaires were analysed using descriptive and inferential statistics such as me.....

Kajian ini bertujuan menentukan kesan penggunaan kaedah Suai Gabung Graf (SGG) terhadap kemahiran di dalam topik Gerakan Linear dalam Fizik Tingkatan Empat. Pendekatan kuantitatif digunakan dengan kaedah eksperimen kuasi. Skor pelajar dikumpul dengan menggunakan Penilaian Kemahiran Menggraf Gerakan Linear (PKM). Instrumen tersebut ditadbirkan dalam dua sesi pengujian iaitu praujian dan pascaujian yang setara. Perbandingan min skor pelajar dianalisis menggunakan ujian-t. Seramai 197 orang pelajar Tingkatan Empat telah dipilih sebagai sampel dan dipecahkan kepada dua kumpulan iaitu 101 orang dalam kumpulan kawalan dan 96 orang dalam kumpulan ujikaji. Hasil kajian menunjukkan tahap kemahiran menggraf gerakan linear kedua-dua kumpulan menunjukkan peningkatan yang signifikan. Namun begitu, tiada perbezaan yang signifikan antara min skor pascaujian kedua-dua kumpulan tersebut. Kesimpulannya, kaedah SGG memberikan kesan interaksi positif yang lebih tinggi terhadap kemahiran menggraf gerakan l.....

Kajian ini bertujuan untuk meneroka penggunaan Model Refleksi Evolusi dalam pengajaran. Reka bentuk kajian kes digunakan untuk meneroka secara mendalam proses pemikiran guru semasa melakukan refleksi berdasarkan Model Refleksi Evolusi. Data dikumpul melalui temu bual sebelum pengajaran dan selepas pengajaran, pemerhatian pengajaran dan penelitian dokumen. Seramai 12 orang guru bahasa yang terdiri daripada 4 orang guru Bahasa Melayu, 4 orang guru Bahasa Inggeris dan 4 orang guru Bahasa Tamil. Dapatan kajian menunjukkan bahawa Model Refleksi Evolusi merangsang pemikiran guru-guru bahasa untuk mengamalkan refleksi secara sistematik ke arah mempertingkatkan kemahiran mengajar mereka. Guru-guru yang mengamalkan secara berurutan langkah-langkah Model Refleksi Evolusi didapati lebih sistematik dalam membuat perancangan mengajar, pemilihan strategi pengajaran, pemilihan bahan, membuat penerangan dan membuat penilaian. Manakala guru-guru yang mengamalkan langkah-langkah secara tidak berurutan M.....

The purpose of this study was to determine the underlying constructs of an instrument to measure self-regulated learning (SRL), examine the correlation between SRL and academic performance, determine the SRL predictors of academic performance and how gender and age moderated this relationship among nontraditional learners (n=519) in the Primary School Graduate Program (PGSR). Factor analyses, Pearson bivariate correlation, linear regression analysis and moderated multiple regression analyses were performed. Additionally, this study examined the barriers to learning and how SRL could be utilized to resolve these barriers. The items in the Self-Regulated Learning Questionnaire (Sf-ReLQ) was found to comprise a robust scale. Findings revealed that there was a moderately significant relationship between SRL and academic performance. An intriguing finding was the insignificant negative correlation of time study management and academic performance. Overall results of the multiple regression .....

Kajian ini melibatkan dua peringkat, iaitu kajian awal secara tinjauan dan kajian eksperimen. Terdapat tiga (3) tujuan kajian awal iaitu; Pertama, mengukur tahap stres secara keseluruhan; Kedua, mengukur tahap elemen-elemen simptom stres iaitu Somatizasi (SOM), Obsesif- Kompulsif (OC), interpersonal-Sensitiviti (IS), Kemurungan (DEP, Kebimbangan (ANX), Permusuhan (HOS), Fobia (POB), Pemikiran Paranoid (PAR), Psikotisme (PSY) dan Dimensi Tambahan (AD); dan Ketiga, mengukur tahap stres keseluruhan berdasarkan daerah bertugas dalam kalangan staf Jabatan Kebajikan Masyarakat (JKM) negeri Johor. Kajian awal melibatkan subjek kajian seramai 240 orang (120 lelaki; 120 perempuan) dipilih secara persampelan rawak berstrata. Data dikumpul menggunakan Inventori Simptom SCLR-R-90 (Symptom Inventory version of the SCL-R-90) dan dianálisis secara perbandingan peratusan dan min. Dapatan kajian tinjauan menunjukkan 23% subjek mengalami tahap stres yang tinggi. Antara elemen stres pula menunjukkan tah.....

Penggunaan gaya bahasa dalam puisi berbeza antara kesusasteraan Arab dengan kesusasteraan Melayu. Gaya bahasa ini memainkan peranan dalam menghasilkan karya sastera yang indah. Walau bagaimanapun, kajian yang dijalankan terhadap gaya bahasa puisi adalah sedikit dibandingkan dengan prosa. Oleh itu, gaya bahasa "ilm al-bayan dalam kesusasteraan Arab dan gaya bahasa perbandingan dalam kesusasteraan Melayu dipilih sebagai dua perkara pokok yang dikaji. Konsep puisi bagi kedua dua kesusasteraan yang berbeza turut dikaji. Teks daripada Diwan Abi Tammam dan Syair Siti Zubaidah dipilih untuk dianalisis bagi melihat persamaan dan perbezaan gaya bahasa yang terkandung dalam kedua-dua teks puisi tersebut. Pendekatan kepustakaan digunakan untuk mengumpul maklumat-maklumat yang berkaitan dengan kajian. Kajian ini turut menganalisis tanda atau lambang yang terdapat dalam Diwan Abi Tammam dan Syair Siti Zubaidah dengan menggunakan teori semiotik Charles Sander Pierce. Pendekatan bandingan pula diguna.....

This is a study on how to improve the writing ability of Form Three students in a secondary school in Ipoh, Perak. The use of model essay and process writing was applied to this research to find out their effectiveness in improving students' writing ability. The data was collected from essays written by a Form Three student who was the sample for this research. In my experience as an English teacher for 18 years, I found that many students were weak in writing essays due to the effectiveness when presenting points in essay. Students often committed grammatical errors in their essays. Insufficient knowledge, lack of exposure to reading materials and also lack of practice may have contributed to this weakness. Most of the time students were given guided essays and after a short discussion they were told to write the essay. The study showed that the sample's essay has improved through the use of model essays aided by the process writing method. By using model essays, the sample was able t.....
