ABSTRAK

Tujuan utama kajian ini adalah untuk menghasilkan bukti kesahan dan kebolehpercayaan metrik pengukuran kebergunaan perisian kursus matematik secara psikometrik dan seterusnya membentuk rumus skor kebergunaan. Kertas ini membincangkan pembentukan rumus kebergunaan. Berdasarkan pandangan secara teori, satu model hipotesis kebergunaan dengan tiga faktor iaitu kebolehgunaan, kefungsian dan kecekapan dan 85 metrik dicadangkan. Melalui pengesahan pakar dan ujian kebolehpercayaan metrik kebergunaan dikurangkan kepada 64. Instrumen dengan 64 metrik ditadbir ke atas 620 guru matematik di lima zon di Malaysia. Mereka diminta melayari perisian kursus matematik (PKM) sambil melengkapkan instrumen. Analisis faktor penjelajahan dilakukan untuk mengesahkan konstruk kebergunaan manakala analisis faktor pengesahan dijalankan untuk membentuk model berstruktur dengan memadankan 34 metrik dengan model hipotesis. Ujian-t dan ujian ANOVA mendapati tiga pembolehubah iaitu, bidang pengkhususan guru, pengalaman menggunakan komputer dan ralat penilaian menyumbang kepada skor kebergunaan. Dapatan ini digunakan untuk membentuk rumus kebergunaan PKM.

Kata kunci: Metrik kebergunaan; model kebergunaan; pengesan ralat; ralat penilaian; skor kebergunaan

ABSTRACT

The primary purpose of this study was to provide psychometriks evidence of validity and reliability of metriks for evaluating the usefulness of a mathematics courseware (MC) and eventually to construct the usefulness score formula. In this paper the construction of usefulness score is discussed. Based on the theoretical perspective, a hypothesized evaluation model with three factors which were usability, functionality and efficiency and 85 metriks were proposed. The instrument was administered to 620 mathematics teachers in five regions in Malaysia. They were required to explore a MC and complete the questionnaire. Exploratory factor analysis was employed to validate the usefulness construct while confirmatory factor analysis was conducted to develop a structural model by befitting 34 metric with the hypothesis model. T-test and ANOVA suggested that three variables, which were teacher’s academic background, computer usage experience and evaluation error, had significant impact to MC usefulness score. From these findings MC usefulness score formula was constructed.

Keywords: Evaluation error; safeguards; usefulness metriks; usefulness model; usefulness score
