4.4.1. Development of the GC instructional worksheets and instrument
Before the experimental research was conducted, a proper plan for the development of the GC instructional worksheets and instrument
were drafted and designed. In the development process, the GC instructional worksheets were developed for the four chosen topics as per
the probability syllabus and based on the ‘balance approach’ as mentioned earlier. Four problem solving questions on the four chosen topics
were set in the PAT. The development of the GC instructional worksheets took for about 5 months, whereas the development of the PAT took
for about 1 month.
