This study aimed to integrate blended teaching approach to explore students' satisfaction and measure its effectiveness in undergraduate curriculum. Moreover, study aims to find out the difference in academic achievement of students in blended and traditional mode. The population of the study was all BS programmes students of Institute of Education and Research (IER) enrolled in Spring semester 2018. The Purposive sampling technique was employed for desired sample. All BS science education students (N=51) were selected as sample for this pedagogical intervention. Blended learning toolkit was adapted to measure the perception, satisfaction and effectiveness of undergraduate students. The reliability of the instrument was α = .883. The 50% content were taught through face to face interaction and remaining 50% through an online blog. Study found that integration of blended learning approach has influenced academic achievement of students because students' mean scores were higher in blended mode (M=42.0) contrary to traditional mode (M= 36.5). Most importantly, students claimed that blended learning approach was cost and time effective. Study concluded that blended learning facilitates students in conceptual understanding and students considering blended mode of teaching more effective, interactive, and productive.
