Access to quality education is still a major bottleneck in developing countries. Efforts at opening the access to a large majority of citizens in developing nations have explored different strategies including the use of multimedia technology. This paper provides a systematic review of different multimedia tools in the teaching and learning processes with a view to examining how multimedia technologies have proven to be a veritable strategy for bridging the gap in the provision of unrestricted access to quality education and improved learners' performance. The review process includes conducting an extensive search of relevant scientific literature, selection of relevant studies using a predetermined inclusion criteria, literature analysis, and synthesis of the findings of the various studies that have investigated how multimedia have been used for learning and teaching processes. The review examines various case study reports of multimedia tools, their success and limiting factors, application areas, evaluation methodologies, technology components, and age groups targeted by the tools. Future research directions are also provided. Apart from text and images, existing tools were found to have multimedia components such as audio, video, animation and 3-D. The study concluded that the majority of the multimedia solutions deployed for teaching and learning target the solution to the pedagogical content of the subject of interest and the user audience of the solution while the success of the different multimedia tools that have been used on the various target groups and subjects can be attributed to the technologies and components embedded in their development.

Yoruba festivals are numerous and multifarious. For this reason, some are of the view that the Yorubas are deeply spiritual. In addition to the generally celebrated festivals among the Yorubas, each Yoruba tribe has its own festivals. A series of these festivals called the Ojude Oba festival is celebrated by the Ijebus who are renowned for both their enterprise and affluence. This article examines the cultural and spiritual significance of the Ojude Oba festival. It analyzes the early beginnings of the festival while providing insights into the epoch of the Ijebus. The festival constitutes a major commercial activity that brings about economic integration and development of the Ijebu community. This article argues that the Ojude Oba festival should not be seen simply for its entertainment value, but as a manifestation of Yoruba cultural, socio-economic, and spiritual values.

One of the most direct methods of exposing corruption in corporate or public institutions is whistleblowing. Quite a number of countries, including Nigeria, have introduced a whistleblowing policy. Among its provisions is to deter corrupt behaviours and guide formal investigations into them. However, Nigeria still lags far behind in this respect, perhaps out of structural inertia in dealing with corruption cases. In this article, the author argues that Nigeria can benefit from the institutional, educational and spiritual framework embedded in whistleblowing in Islam through ‘amr bi-l-ma'rūf wa-naḥy ‘an al-munkar i.e., enjoining good and forbidding wrong. The article, through historical and descriptive approaches, explains the policy of whistleblowing from the Islamic perspective, hence, clarifying some Muslims misconceptions. This study, therefore, presents Islamic principles on the whistleblowing policy and explains some pivotal approaches to addressing whistleblowing policy in Nigeria.
