Analisis Prestasi Calon

A. Kumpulan Calon prestasi rendah

i. Kurang mahir menggunakan K11 ( what is changed)

ii. Cenderung menyalin pembolehubah tidak lengkap (tanpa parameter)

yang diberi dalam jadual sebagai jawapan.

iii Jika jawapan bagi kriteria 11 salah, maka jawapan murid bagi

soalan K6, K8, K9,K10 juga akan salah (kesan domino). Ini kerana

jawapan bagi K11 juga merupakan jawapan dalam K6, K8, K9,K10

Catatan:

K6 - Membuat pernyataan tentang maksud data atau maklumat terkumpul

K8 - Menyatakan hubungan antara pembolehubahK9 - Membuat kesimpulan berdasarkan maklumat yang terkumpul
