This paper discusses the development and validation of a concept inventory for interpreting kinematics graphs in the Tanzanian context. The study involved 61 participants comprising physics pre-service teachers, secondary school teachers, diploma college tutors, and a university lecturer from Tanzania. We developed 25 multiple-choice questions for interpreting kinematics graphs. The different steps in the development process used are selecting the topic, setting objectives, constructing questions, validating questions, and reliability testing. We carried out descriptive and inferential statistical analysis by using Statistical Package for Social Science (SPSS) version 22 followed by item analysis for pre-and post-piloting. Findings revealed normal distribution scores with a mean and standard deviation of 39.28±10.893 for pre-piloting and 40.16±8.08 for post-piloting. It also revealed no significant difference between pre-and post-piloting results with a p-value of 0.414.  In addition, correlation coefficients for test re-test reliability were .783 and .878 for single and average measures respectively. Moreover, item analysis in terms of difficulty index, discrimination index, and distractor efficiency agreed with the published standards. Based on these findings, the study recommends the use of developed and validated kinematics graphs concept inventory by physics educators in both research and classroom instructions in the Tanzanian context.

Compliance with any policies, laws and regulations, including university compliance with quality assurance mechanisms globally, depends on the practicability of those mechanisms. Like other countries, Tanzania has quality assurance mechanisms that require universities to comply. However, the existing audit reports have shown non-compliance cases to such mechanisms. This study sought to explore the practicability of the existing quality assurance mechanisms in promoting universities’ compliance in Tanzania. The documentary reviews, interviews, and focus group discussions were used to collect data from the 4 universities and 46 students, academics, and quality assurance directors and officers as a sample size selected purposively. The data were analysed through content analysis. The findings revealed that the existing quality assurance mechanisms are generally practicable; however, there are quality assurance requirements with practicability challenges due to contextual factors. Such requirements include senior academics in administrative duties, academics’ promotion, academics’ recruitment, inclusive and participatory teaching approaches, requirements with extra financial costs, examination scripts’ marking, and invigilation restrictions. This study concludes that the practicability challenges of some quality assurance mechanisms are one reason for non-compliance cases at some Tanzanian universities. It recommends that key stakeholders be involved in establishing mechanisms, and all contextual factors must be addressed to enhance practicability.
