Kajian ini bertujuan membina dan menguji kebolehgunaan modul pengajaran berasaskan peta pemikiran i-Think bagi topik Nisbah, Kadar dan Kadaran. Modul pengajaran dibina berdasarkan model Sidek dan model ASSURE dikenali sebagai modul pengajaran berasaskan peta pemikiran i-Think bagi topik Nisbah, Kadar dan Kadaran untuk mata pelajaran Matematik Tingkatan Dua (Pp-Mt2). Nilai kesahan kandungan bagi modul Pp-Mt2 yang di sahkan oleh empat orang pakar adalah baik (86.67%). Manakala kesahan instrumen soal selidik diperolehi melalui semakan tiga orang pakar yang mendapati instrumen adalah baik dan mencukupi bagi mengukur kebolehgunaan modul. Analisis kajian rintis menunjukkan nilai kebolehpercayaan instrumen adalah tinggi dengan nilai alfa Cronbach sebanyak 0.882. Modul Pp-Mt2 diuji kebolehgunaannya melalui kaedah tinjauan terhadap 57 orang sampel yang terdiri daripada guru Matematik Tingkatan Dua di daerah Besut. Dapatan soal selidik yang menggunakan skala Likert lima mata menunjukkan responde.....

Novel coronavirus (COVID-19) was discovered in Wuhan, China in December 2019, and has affected millions of lives worldwide. On 29th April 2020, Malaysia reported more than 5,000 COVID-19 cases; the second highest in the Southeast Asian region after Singapore. Recently, a forecasting model was developed to measure and predict COVID-19 cases in Malaysia on daily basis for the next 10 days using previously-confirmed cases. A Recurrent Forecasting-Singular Spectrum Analysis (RF-SSA) is proposed by establishing L and ET parameters via several tests. The advantage of using this forecasting model is it would discriminate noise in a time series trend and produce significant forecasting results. The RF-SSA model assessment was based on the official COVID-19 data released by the World Health Organization (WHO) to predict daily confirmed cases between 30th April and 31st May, 2020. These results revealed that parameter L = 5 (T/20) for the RF-SSA model was indeed suitable for short-time series ou.....
