Abstract: The purpose of this study was to investigate the performance of chemistry in Zanzibar Secondary Schools. It was conducted in all regions of Zanzibar in public and private secondary schools and Ministry of Education officials. The objective of the study included finding out causes of poor performance in chemistry. Views, opinions, and suggestions of teachers and students to improve performance of chemistry and a descriptive survey was adopted for the study. 45 teachers and 200 students were randomly sampled from 15 secondary schools in Zanzibar and ten Ministry of Education officials were purposively sampled for the study. Questionnaires and open-ended interview schedules were the main instruments used in obtaining relevant data from respondents. Data collected from the field was analyzed both qualitatively and quantitatively. Qualitative analysis involved content analysis of the responses obtained through interviews and quantitative analysis involved generation of tables, frequencies and percentages. The results revealed that there were shortages of trained teachers, lack of proficiency in the language of instruction (English) and major facilities like laboratories and books. These led to poor delivery of subject matter and consequently resulting in poor performance. Based on the findings, this study recommends that provision of trained, competent, and effective teachers as vital aspects to be considered. Government through Ministry of Education should put effort to stalk libraries and equip laboratories with modern books and instruments. In addition, the ministry should strengthen teachers’ training and encourage use of instructional media in class and make conducive learning environment to both teachers and students.
Abstract: This paper presents the design, development and
evaluation of an application prototype developed to support
tuberculosis (TB) patients’ treatment adherence. The system makes
use of graphics and voice reminders as opposed to text messaging to
encourage patients to follow their medication routine. To evaluate the
effect of the prototype applications, participants were given mobile
phones on which the reminder system was installed. Thirty-eight
people, including TB health workers and patients from Zanzibar,
Tanzania, participated in the evaluation exercises. The results
indicate that the participants found the mobile image-based
application is useful to support TB treatment. All participants
understood and interpreted the intended meaning of every image
correctly. The study findings revealed that the use of a mobile visualbased
application may have potential benefit to support TB patients
(both literate and illiterate) in their treatment processes.
