The problem tests of PISA resulted that 36% of students attained scores above 60. Furthermore, students’ percentage could complete the measuring aspects, predicting aspects, applying concepts, and the inferring aspects were 64%, 38%, 36%, and 42%. Students’ percentage based on observation instruments' results were predicting 52%, applying concepts 43%, measuring 48%, inferring 46%, experimenting 0%, asking question 23%, classifying 37%, communicating 28%, and observing 55%.
