B. Study findings related to the second hypothesis

  1. The study showed that there were statistically significant differences at &=0.01 significance level between the experimental and control groups' independence skills averages in the post-assessment, i.e. after applying the functional curriculum in teaching the experimental group.
  2. The study showed that there were statistically significant differences at a 0.01 significance level, between the average independence skills scores of the experimental group that was taught the functional curriculum, and those of the control group after isolating the effect of the experimental group's pre-assessment scores. Therefore, the proposed functional curriculum is effective in helping students with moderate intellectual disabilities acquire functional skills.
  3. The results of the associated variance analysis revealed that there were statistically significant differences at a 0.01 significance level, between the experimental group and the control group in favour of the former, in strands 1, 2, 3, 4, 6, 7 and 8, after isolating the effect of the associated variable (experimental group pre-assessment scores).
  4. The study showed that there were no statistically significant differences at a 0.05 significance level between the experimental group and the control group in the post-assessment score in the security and safety strand, even after teaching the former the functional curriculum.

Figure 11. Differences between the calculated averages of the experimental and control groups in the pre- and post-assessment in the self-care strand

Line graph that shows the differences between the calculated averages of the experimental and control groups in the pre- and post-assessment in the self-care strand. In the pre-assessment strand, the calculated average of the control group is between 31 and 32 and the calculated average of the experimental group is almost 35. In the post-assessment strand, the calculated average of the control group is between 32 and 33 and the calculated average of the experimental group is between 36 and 37.

Line graph that shows the differences between the calculated averages of the experimental and control groups in the pre- and post-assessment in the domestic skills strand. In the pre-assessment strand, the calculated average of the control group is between 7 and 8 and the calculated average of the experimental group is between 10 and 12. In the post-assessment strand, the calculated average of the control group is between 7 and 9 and the calculated average of the experimental group is between 16 and 18.

Figure 13. Differences between the calculated averages of the experimental and control groups in the pre- and post-assessment in the first-aid strand

Line graph that shows the differences between the calculated averages of the experimental and control groups in the pre- and post-assessment in the first-aid strand. In the pre-assessment strand, the calculated averages of the control and experimrntal groups are 0. In the post-assessment strand, the calculated average of the control group is 0 and the calculated average of the experimental group is almost 3.

Figure 14. Differences between the calculated averages of the experimental and control groups in the pre- and post-assessment in the telephone use strand

Line graph that shows the differences between the calculated averages of the experimental and control groups in the pre- and post-assessment in the telephone use strand. In the pre-assessment strand, the calculated average of the control group is almost 1 and the calculated average of the experimrntal group is between 0.8 and 1. In the post-assessment strand, the calculated average of the control group is almost 1 and the calculated average of the experimental group is between 1.4 and 1.6.

Line graph that shows the differences between the calculated averages of the experimental and control groups in the pre- and post-assessment in the security and safety strand. In both assessment strands, the calculated average of the control group is between 0.5 and 0.6 and the calculated average of the experimental group is between 0.15 and 2.
