dc.description.abstract This study focuses on challenges and prospects of the teaching of the Doppler Effect to grade 12 learners. The challenges of teaching the Doppler Effect were established and these findings influenced the development of activities. These activities were tested, refined and re-tested in an iterative cycle and finally provided prospects on teaching the Doppler Effect. Educational Design Research (EDR) was used to bridge theory and practice in education. This study was done in the Vhembe district in the Limpopo province. In the first cycle, questionnaires and interviews with 32 teachers and a subject advisor were used to establish the baseline with regards to the challenges of teaching the Doppler Effect. After the analysis of the data which forms the first cycle of EDR, the content and methodological problems faced by teachers when teaching the Doppler Effect were revealed. In the second cycle of the EDR, learning activities were developed that was informed by the analysis and tried out in 2 schools by learners and their teachers. Completed activity sheets were marked and the results were used to determine if there were a correlation between the activity sheets and the written test. Problems were documented and changes to the activities were again made and tried out in 10 schools by 216 learners with the help of 10 teachers. The data collected from the learners` work sheets were analysed. Pearson`s product moment correlation has shown that there is a statistically significant relationship (r = 0.65; p < 0.01) that exists between these design-research activities and solving of problems on the Doppler Effect. An instructional manual was developed comprising of the final activities. This was distributed amongst the district officials and teachers to assist them in the teaching of the Doppler Effect in the Vhembe district. en
