The study investigated the effect of three modes of mobile augmented learning strategies on pre-service teacher learning outcomes in machine woodwork. It focused on determining the effects of mobile blog of Video, Audio and Text on academic achievement and retention of pre-service teachers. Two research questions and two corresponding hypotheses were formulated and tested in the study. The study adopted a quasi-experimental design and the population of the study comprised 350 woodwork students in the six Federal and State Government owned Colleges of Education in the seven North-Western states. The sample was 144 males and 42 females NCE III Woodwork students making a grand total 186. Two instruments constructed by the researcher used for data collection were: Machine woodwork Achievement Test (MWAT) and Machine Woodwork Retention Test (MWRT). MWAT was pilot tested using test-retest method and reliability index of 0.86 was obtained. The study findings showed that there was significant difference in the academic achievement of pre-service teachers taught machine woodwork using Vblog, Ablog and Tblog in favour of the Ablog. There was also a significant difference in the mean retention scores of pre-service teachers taught machine woodwork using Vblog, Ablog and Tblog in favour of Tblog. The study, therefore, concluded that video blog is more effective in enhancing students' academic achievement in machine woodwork and development of positive attitude towards machine woodworking.
