Despite of several efforts made by stakeholders in alleviating the problem, it still persists. This might have been caused by among others, the lack of appropriate teaching aids to aid demonstration of difficult concepts in the subject. The objective of the study was to develop educational multimedia teaching aids for Hydraulic Press System and Screw and Jack sub-topic prototypes from the topic of simple machine in Physics subject book two and assess their effectiveness in complementing classroom teaching in selected secondary schools. The study was both qualitative and quantitative in nature, with semi-structured questionnaires for assessment of interactive educational multimedia courseware as quantitative part, and collected data from 134 students from three selected secondary schools from Dar es Salaam and Singida regions. Prior to development and assessment of multimedia teaching aids, requirements for system design were collected from 80 form two students and 3 Physics teachers from Jangwani girls and St. Anthony secondary schools in Ilala and Temeke municipal councils in Dar es Salaam region. Requirements were also collected from interview with examination officers from NECTA as well as from documentary review. The study findings revealed that the developed multimedia teaching aid prototype assisted 88.8 per cent of the students to understand difficult concepts in Physics more clearly, and about 74 per cent of them were motivated to learn the subject; thus improving their way of learning the subject.enPhysicsStudy and teaching (Secondary)Aids and devicesAudio-visual aidsSecondary schoolsTanzaniaThesis
