Impact of Team Teaching on Mathematics Students' Achievement in Tertiary Institutions in Delta State

Abstract

The study aims to examine the impact of team teaching on mathematics student's achievement in tertiary institutions in Delta State. A quasi-experimental research design will be employed, utilizing a pretest-posttest control group approach. The experimental group will experience mathematics instruction through a team-teaching model, while the control group will continue with conventional single-teacher methods. The experiment will be conducted before and after the intervention to measure changes in learning outcomes, student engagement, and teacher professional development. The study is based on a sample of mathematics lecturers from the Federal College of Education (Technical) Asaba and Dennis Osadebay University Asaba in Oshimili South Local Government Area of Delta State, Nigeria. The sample will be divided into two groups: a control group and a group with a single teacher. The control group receives a questionnaire to measure students' levels of engagement and participation in mathematics lessons. The group will receive a pre-and post-test test to determine how team teaching improves students' academic performance in mathematics. Results from the study indicate that team teaching enhances problem-solving skills, academic performance, and student engagement in mathematics classes. In conclusion, it was recommended that: Tertiary institutions should incorporate team teaching into mathematics curricula to enhance student understanding and academic performance ;Regular training and workshops should be organized to equip lecturers with effective team-teaching skills; Clear communication and role definition among teaching team members are essential to avoid confusion and ensure productive collaboration; Institutions should monitor and evaluate the outcomes of team teaching to identify areas for improvement and measure its impact on student achievement and Encouraging interdisciplinary team teaching can help students connect mathematical concepts to real-world applications, enriching their learning experience.
