This study aimed to investigate the effect of conceptual change text (CCT) in the REACT strategy for students' conceptions of solutions. A quasi-experimental method was used in the study. The study was carried out in the spring term of the 2012–2013 academic year with 61 freshmen students (aged 18–20 years) studying in the Elementary Education Department. To gather data, the solutions concept test (SCT) was used as a pretest (PrT) and posttest (PoT) and clinical interviews were used to increase the validity of the data obtained from SCT. In the experimental and control groups, the REACT strategy was used as the teaching strategy. In the experimental group, the REACT strategy was enriched with CCTs. Three CCTs were used for the experimental group. According to the findings, there was a significant difference between the experimental and control groups' PrT and PoT results. The REACT strategy was found to be successful at dealing with the alternative conceptions in solution chemistry. However, no significant difference was found between the groups' PoT results. On the other hand, qualitative analyses showed that the CCTs were slightly effective in remediation of alternative conceptions in solution chemistry. This suggests that we may need to use more than one intervention model to effectively remedy the alternative conceptions in solution chemistry. This study may be helpful for diagnosing alternative conceptions and guide researchers to remedy them. Hence, CCTs can be designed for other chemistry topics for implementation in schools.

This study was intended to examine the effect of teacher scaffolding on grade nine students’ paragraph writing performance in Meneguzer secondary school, Amhara-Ethiopia. The study employed a quasi-experimental research design with explanatory sequential mixed methods of data collection and analysis. There were experimental and control groups of students including 40 students in each group. Test, questionnaire and interview were used to gather data. The quantitative data were analysed using an independent sample t-test, whereas the qualitative data were analysed thematically.  The pre-test yielded a significant value of sig. (2-tailed) =0.659 which was higher than α =0.05. This showed that both the experimental and the control groups of students were equal and homogenous in their writing performance before treatment. However, after the treatment, there was a significant difference between the writing performance of the students in the two groups as the analysis of writing test in post-test yielded sig. (2- tailed) =0.025 which was smaller than α = 0.05. This implies that the treatment enabled the participants in the experimental group to improve their writing skills. The result of the questionnaire and interview analyses further revealed that the experimental group of participants were motivated and initiated by the teacher scaffolding to improve their writing skills. Thus, it can be concluded that teacher scaffolding has a positive significant effect on students’ writing skills. As a result, it motivates students to practice their writing skills independently.

<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>

Background: The present study aimed to evaluate the effect of cold dialysis solution on the sexual dysfunction of patients with chronic renal failure undergoing hemodialysis. Methods: This randomized clinical trial was conducted with a before and after parallel design among 60 hemodialysis patients diagnosed with sexual dysfunction. The selected subjects were randomly allocated to the two groups of experimental and control (30 per each). Patients in the experimental and control groups underwent hemodialysis for one month using 35.5°C and 37°C dialysis solutions, respectively. Following the procedure, male and female sexual function was assessed in the study groups. Data were collected using the International Index of Erectile Functions, the female sexual function index (FSFI), and a demographic questionnaire. Data analysis was performed using Chi-square, Fisher's exact test, Mann-Whitney U test, t-test, paired t-test, and Wilcoxon test at 95% confidence interval. Results: No significant difference was observed between the experimental and control groups regarding male sexual function before and after the intervention (P > 0.05). However, the Mann-Whitney U test indicated a significant difference in the female subjects’ arousal in the experimental group before (3.68 ± 0.38) and after the intervention (3.98 ± 0.46; z = 2.216; P = 0.027). Conclusions: Cold dialysis solution could only increase the sexual arousal of the women in the experimental group, and no changes were observed in other sexual function domains of the male and female patients. Given the short duration of our intervention, it is recommended that further longitudinal studies be performed on larger cohorts of patients in different geographical regions.
