<p><em>Generally, the performance of students in organic chemistry in Zambia is not encouraging. This can be attributed to the nature of the subject in addition to other factors. This study explored the composite effect of concept mapping and ICT on students’ performance in selected topics in organic chemistry. One hundred and thirty-four grade 12 students were involved. Data was collected using an organic chemistry performance test. A pre-test, the post-test quasi-experimental design was adopted. The study comprised of three</em><em> </em><em>groups randomly assigned to experimental group one, experimental group two and a control group. Experimental group one was taught using concept mapping, experimental group two was taught using a combination of concept mapping and ICT and the control group was taught using conventional methods (discussion). ANOVA results for the three groups were F (2,131) = 2.237 and p = 0.111. This indicates that there was no significant difference amongst the three groups at the beginning of the study. After treatment the results revealed that experimental group two outperformed the other two groups with a p valuep-value</em><em> </em><em>0 at F (2,131) = 2.237 at ? = 0.05. Post hoc analysis using Fisher’s </em><em>L</em><em>east </em><em>S</em><em>ignificant </em><em>D</em><em>ifference (LSD) test showed that the mean scores were statistically significant amongst the three groups. A very large effect was seen between experimental group one and control and between experimental group two and control. A sizable effect was seen between experimental group one and two. The conclusion is that using concept mapping with ICT has a positive effect on the performance of students in organic chemistry. The results corroborate the findings of studies that the use of concept mapping and ICT teaching strategy improves the performance of students. Consequently, this study seems to offer a positive solution towards the enhancement of students’ performance in organic chemistry in secondary schools.</em></p>

The study aims at finding out the effect of process-based writing teaching supported by students' reflection on their performance in, and attitude toward writing. It hypothesizes that there is no statistically significant difference between the mean score of the experimental group taught writing according to the reflection-supported process-based approach and the control group taught writing according to the process-based approach in the writing performance test and writing attitude scale. To achieve the aims of the study, two second year sections in the Department of English of the College of Education/ Ibn Rushd for Human Sciences are randomly assigned as the experimental and control groups with 43 and 45 students respectively. The experiment in this study lasts for 15 weeks during which both groups are taught writing according to the process approach and given one writing assignment per week. Only the experimental group students are required to reflect on their writing performance in every writing assignment by using a reflection sheet prepared for this purpose. At the end of the experiment, the two instruments of the study, i.e., a writing performance test and attitude toward writing scale are administered on both groups. The statistical manipulation of the results achieved shows that supporting the process orientation to writing teaching with a phase of students reflection on their writing performance is effective in developing their writing performance and helping them formulate positive attitude toward writing. In the light of the results and conclusions achieved, a set of recommendations is put forward.
