Effectiveness Of Constructivist Strategies With Lecture In Science

Abstract

The constructivist approach is a philosophy of teaching in which a learner constructs their knowledge with the help of their previous experiences. The constructivist approach advocates the teaching method and strategies which gives more scope to the learners in the classroom.This approach offers many strategies for teaching science which promote the construction of knowledge by the learners.This paper is intended to investigate the effectiveness of constructivist strategies with the lecture method. In the present study, the researcher has used the “pre-test post-test non-equivalent control group” design. All students of standard 9^thof Vadodara city were considered as the population of the study.Two schools in Vadodara city have been purposively selected by the researcher. The sample of 100 (55 in the experimental group and 45 in the con[1]trol group) students who were studying in standard 9^th. For Intervention, the syllabus suggested by NCERT has been followed by the researcher.The researcher has given intervention for amonth. During the intervention, the researcher used constructivist strategies with the lecture method according to the demand for content.For data collection, a self-made achievement test has been used. The researcher has used the Mann-Whitney U testto analyze the data. The finding revealed that if constructivist strategies are used with the lecture in the classroom for teaching science,then the achievement of studentsbecomes enhanced in comparison to the lecture.
