Acquisition of Higher-Order Cognitive Skills (HOCS) Using the Flipped Classroom Model: A Quasi-Experimental Study.

Abstract

IntroductionFlipped classroom refers to a teaching model where the lecture and homework elements of the class are reversed. Students develop knowledge and understanding during the pre-class session, and use the in-class time for active learning such as small group discussions, wherein they are expected to develop the skills of problem-solving (application) and critical thinking (analysis). An educational psychologist, Benjamin Bloom, proposed Bloom’s Taxonomy for the cognitive domain. According to this taxonomy, knowledge, and understanding have been considered to be lower-order cognitive skills (LOCS), while application (problem-solving), analysis (critical thinking), synthesis, and evaluation have been considered higher-order cognitive skills (HOCS). Only one study has reported that flipped classroom approach helps in the acquisition of HOCS such as application, analysis, synthesis, and evaluation. The present study aims to compare the flipped classroom model with the traditional lecture model and focuses particularly on the acquisition of HOCS such as application and analysis, by assessing the students using multiple-choice questions based on clinical vignettes.MethodsThe study was conducted in the Department of Physiology at Government Medical College, Bhavnagar. A total of 102 students in two groups, Group A (n=52) and Group B (n=50), participated in all the phases of the study. In the flipped classroom group, students watched the pre-recorded videos and studied standard textbooks, followed by a group discussion in the class. The traditional Lecture group attended the didactic lecture only. Topic I was taught to Group A using the flipped classroom model and to Group B using the traditional didactic lecture approach. Topic II was taught to Group B by using the flipped classroom method and to Group A using the traditional didactic lecture.Both groups of students were assessed after a gap of one week with multiple-choice questions based on clinical vignettes for checking the HOCS. These questions were designed based on Blooming Biology Tool (BBT).The feedback collected responses regarding the learning experience, perceived value of the flipped classroom, the course materials, the teaching process, and the evaluation system.ResultsThe students, who participated in the flipped classrooms, performed statistically better than those in the traditional lecture model (5.36 ± 1.69 vs. 4.94 ± 1.34) (p<0.05). The students strongly agreed that the flipped classroom method was an enjoyable way of learning: it enhanced their problem solving and analytical ability as well as developed their ability to work as team members and plan their own work. Students in both the flipped classrooms gave a similar perception indicated by the small effect size (r <0.3).ConclusionThe pre-class time of the flipped classroom model helps students remember the facts and understand the concepts (both lower-order cognitive skills), and uses the valuable in-class time to master the application of the concepts and critically analyze them (application and analysis being higher-order cognitive skills).
