Abstract	This paper discusses importance of technology education and evidence of declining performance of junior secondary school students in basic technology subject. Benefits of PowerPoint presentation in classroom instruction as a means to improve classroom teaching in the developing countries are also discussed. The effectiveness of PowerPoint Presentation (PPT) for teaching Technical Drawing concepts in Basic Technology was determined using a pretest-posttest, non-equivalent, non-randomized experimental group design. A 2x2x3 factorial design was employed. One hundred JSS 1 students (53 male and 47 female) categorized into 29 high, 54 medium and 17 low achievers from two secondary schools in Abuja Metropolis formed the sample. The schools were randomly assigned to experimental and control groups. The experimental group was taught some selected concepts from Technical Drawing using PowerPoint Presentation (PPT) while Chalkboard method (CB) was used for the control group. A validated Technical Drawing Achievement Test (TDAT) comprising a 25-item multiple-choice test was employed for data collection. The reliability coefficient of TDAT was 0.88 using Kuder-Richardson (KR-20). The hypotheses were tested using ANCOVA and Sidak post-hoc analysis. Results revealed that the students taught with PPT performed better than their counterparts taught with CB. Also, high achievers performed better than medium and low achievers respectfully. The PPT was found also to be gender friendly. Based on the findings, it was recommended that the use of PPT should be encouraged in Nigerian schools. (As Provided).
