Early education in the Qur'an is expected to produce young people having a strong mental foundation, education not only makes children as prosperous in the world, but also provides sufficient provisions to both improve their religion and practice their scriptures. To be able to practice the Holy Qur'an correctly, children must be guided and taught how to read the Qur'an properly in accordance with the rules of true recitation.

As time goes by, the Qur'an learning at MI Al-Hidayah has increasingly developed by applying the so-called Wafa method.

The purpose of this study was to evaluate the relative effectiveness of Plasma TV (PTV) integration in teaching secondary school Biology at Haramaya University Secondary Model School Ethiopia. The sample consisted of 48 students from Grade 9 and were randomly split into control [non-plasma TV] and experimental [plasma TV] groups. A chapter on “Cell Biology” was taught to the two groups by two teachers having similar qualifications for a month's time. After the treatment, post-test was administered to the subjects. Independent-sample t-test was used to determine whether there was a statistically significant difference in the mean scores of the two groups. The analysis of data indicated that there were no significant differences in the mean scores between the two groups on pre and post- tests. Similarly, high achievers in the control and experimental groups didn't significantly differ either. Furthermore, there was no significant mean scores difference between low achievers of control and experimental groups. The results generally implied that teaching students through PTV didn't significantly contribute to better understanding of the lesson compared to the conventional method of teaching. Finally, the present study provides an opportunity to be replicated to make a comprehensive conclusion about the effectiveness of PTV to teach secondary school Biology.

This study investigates the effectiveness of mobile learning in the teaching and learning of Probability. The context of mobile here is not just restrained to gadgets such as smartphones but also the fact that teaching and learning can occur beyond boundaries and anywhere according to the convenience and personal preference of the students. This study made use of the pretest – posttest quasi experimental design and the students chosen for the study were from a pre-university college located in the northern region of the country. A total of 92 students made up the sample of the study. There were 46 students each in the experimental and control groups respectively. Cluster random sampling was employed as the sampling method here. The instrument used to collect data with the aim of strengthening the outcome of the study was the achievement test. A quantitative approach was undertaken specifically to analyse the obtained data. The paired sample t-test and independent sample t-test were executed in the data analysis process. Initially, every student involved in the study regardless of the group they were in possessed equal strength in their understanding of the content being covered as indicated by the results of their pre-test. The paired sample t-test yielded p < 0.05 which meant that there was a significant difference between the mean score of the pre-test and post-test in the experimental group and control group respectively. The outcome of the independent sample t-test showed that there was a significant difference between the mean score of the experimental group and that of the control group in the post-test (p < 0.05). This indicated that the treatment via mobile learning had indeed played a role in the improved performance of students in Probability, hence proving the effectiveness of mobile learning in the teaching and learning of Probability.
