The study investigated the dynamic of blended learning and technology supported learning strategies on tertiary students’ performance in English writing. The sample for the study is made up of ninety (90) students from public tertiary institutions in Ekiti State. Stratified random sampling technique was used to select the ninety (90) respondents from the three (3) sampled higher institutions in the state. The study used a quasi-experimental research method to explore the relationship between variables. The quasi-experimental design for the study was the non-randomized pretest, post-test control group design. The instrument used for data collection was an English Writing Skill Performance Test. Three research questions were raised to guide the study and they were answered descriptively using mean and Standard Deviation. Four research hypotheses were formulated for the study and tested using t-test analysis of independent sample and a two way Analysis of Covariance (ANCOVA). Based on the data analysis, findings revealed that students that were exposed to blended learning instructional strategy significantly outperformed their counterparts who were exposed to technology supported method strategy and those taught using conventional method of teaching. Also, students who were exposed to technology supported method performed significantly higher than those taught using conventional method. It was further found that significant difference existed in gender performance with respect to the two strategies employed in the experimental group. While female students outperformed their male counterpart when been exposed to blended learning strategy, no significant difference existed when they were exposed to technology supported method. Lastly, the study concludes that there was significant effect of blended learning, technology supported and conventional methods on the tertiary students’ learning outcomes in post-test. government, in conjunction with curriculum developers, the federal and state government; other professional bodies like National Universities Commission should create resource centers that can sensitize other stakeholders in the educational sector on the efficacy of blended learning and technology supported learning approach.
