Abstract


Assessment practices of mathematical thinking are an important part of mathematics teachers’ practices. This survey aimed to develop and validate an Assessment Practices of Mathematical Thinking (APMT) instrument. A total of 523 mathematics teachers from Omani public schools were randomly selected as samples. The initial scale consisted of 25 items. The scale was validated by experts in mathematics education and educational measurement and evaluation. Exploratory and confirmatory factor analysis was used to test the APMT model. Results show that the goodness-of-fit indices for the first and second order of the APMT model are placed within the acceptable criteria, and that the magnitudes of loadings for all items are statistically significant. The final version of the APMT scale contains five factors and 21 items. In conclusion, this study has developed an APMT instrument is acceptable psychometrically, and useful to be used for assessing teachers’ assessment practices of mathematical thinking in Arabic context, especially in Oman. The instrument can also be used by teachers for the purpose of self-assessment of their assessment practices of mathematical thinking, which can show their strengths and weaknesses. This instrument is unique because it focuses on different types of assessment practices that can be implemented to evaluate and develop students’ mathematical thinking within and out of the classroom.

Key Words: Mathematical thinking; assessment practices; diagnostic assessment; formative assessment; summative assessment; alternative assessment; electronic assessment; confirmatory factor analysis; exploratory factor analysis; mathematics teachers


Amalan pentaksiran pemikiran matematik adalah bahagian yang penting dalam amalan guru matematik. Kajian tinjauan ini bertujuan untuk membina dan mengesahkan instrumen Amalan Pentaksiran Pemikiran Matematik (APMT). Sebanyak 523 guru matematik dari sekolah-sekolah awam di Oman dipilih secara rawak sebagai sampel. Skala awal terdiri daripada 25 item. Skala ini disahkan oleh pakar dalam pendidikan matematik dan pengukuran dan penilaian pendidikan. Analisis faktor eksploratori dan pengesahan digunakan untuk menguji model APMT. Hasil menunjukkan bahawa indeks goodness-of-fit untuk susunan pertama dan kedua model APMT diletakkan dalam kriteria yang diterima, dan magnitud muatan untuk semua item adalah signifikan secara statistik. Versi akhir skala APMT mengandungi lima faktor dan 21 item. Kesimpulannya, kajian ini telah membina sebuah instrumen APMT yang dapat diterima secara psikometrik, dan berguna untuk digunakan untuk menilai amalan penilaian pemikiran pemikiran matematik guru dalam konteks Arab, terutamanya di Oman. Instrument ini juga boleh digunakan oleh guru untuk tujuan penilaian kendiri amalan penilaian mereka terhadap pemikiran matematik, yang dapat menunjukkan kekuatan dan kelemahan mereka. Instrumen ini unik kerana memberi tumpuan kepada pelbagai jenis amalan penilaian yang boleh dilaksanakan untuk menilai dan mengembangkan pemikiran matematik pelajar di dalam dan di luar kelas.

Kata Kunci: Pemikiran matematik; amalan penilaian; penilaian diagnostik; penilaian formatif; penilaian sumatif; penilaian alternatif; penilaian elektronik; analisis faktor pengesahan; analisis faktor penerokaan; guru matematik
