Abstract

Flipped classroom model is now a well-established learning approach which has brought a paradigm shift by blending technology with the traditional method of teaching. The real meaning of Flipped classroom model is that the traditional lecture method is flipped so that learners get the initial learning material at home and class time is used for cooperative learning. The tools used for the flipped classroom model include Learning management system, social media and like. A lot of research studies exist on Flipped classroom model but these studies lack a unified approach over its significance.  If one set of studies ranks Flipped classroom model better than the traditional lecture method; the other instruction models consider its success due to its integration with technology. There are also studies that associate Flipped classroom model with student-centered approach especially in university education. This article reviews a few of these studies with the objective to understand this debate about the right method of learning; and to identify which studies acknowledge the significance of Flipped classroom model. A set of 33 articles published from 2012 to 2020 were selected for this study. The statistical results show a mixed reaction about the acceptability and adaptability of the Flipped classroom model in the modern learning environment.

Keywords: Flipped classroom model, Learning strategy, Technology, Teaching, Traditional method.

Contribution/ Originality

This study makes a critical review of 33 studies on Flipped classroom model with the view to understand how the previous studies have acknowledge the importance, adaptability and of flipped classroom model in the modern learning environments and also how they differentiated this model from the Traditional Lecture Method.


1. INTRODUCTION

Learning is an essential element of humankind and crucial for the development of a nation (Hafeez et al., 2020). Buckman et al. (2010) stated that there are four important strategies for active learning (1) create individual activities in and out of the classroom (2) integrate students in group activities (3) inspire informal group, and (4) assign project tasks to cooperative students. Engaging these concepts with “Flipped classroom model” involves students to take part in the learning process with full concentration. This model enables students to learn more cooperatively and think critically. It also allows students to share their knowledge with peers (Michel, Cater III, & Varela, 2009). The Flipped classroom model improves the efficacy of learning and increases the motivation level of students to learn actively (Lewis, Chen, & Relan, 2018). The Flipped classroom model of instruction was established by Bergmann and Sams (2012) to deliver lecture to students of secondary schools who had not taken all the classes. In the Flipped classroom instruction model, work is done by the students prior to a class.  The Bloom’s taxonomy related to traditional and flipped learning approaches is shown in Figure 1.

Figure-1. Bloom’s taxonomy related to traditional and flipped learning approaches.

The researches indicate that in Flipped classroom model of instruction, the learners actively participate and achieve better conceptual learning as compared to other traditional lecture methods (Sezer, 2010). Roehl, Reddy, and Shannon (2013) stated the Flipped classroom instruction model can be easily integrated with technology before the class and the class time can be used for active and cooperative learning. The Flipped classroom model also applies student-centered approach for learning process (Abeysekera & Dawson, 2015). Flipped classroom model is getting more attention in educational activities specially in university education (Toppo, 2011). In Flipped classroom model, the traditional lecture method is flipped so that learners get the initial learning material at home and class time is used for cooperative learning. The tools used for the flipped classroom model include Learning management system, YouTube, WhatsApp (Pohl, Bouchachia, & Hellwagner, 2018).

1.1. Flipped Classroom Learning or Blended Learning

Graham, Woodfield, and Harrison (2013) suggested that in blended learning, face to face and computer-based instructions are mixed. The Flipped classroom model of learning is based on online video and audio lectures provided out of the class and the problem-solving discussion sessions are conducted in the classroom. The blended learning is type of learning in which mixed teaching strategy (traditional and information technology) is provided to learners. The blended learning is therefore also called Flipped classroom model of learning (Staker & Horn, 2012).

The comparison between the traditional classroom and Flipped classroom in achieving higher order thinking skills in Blooms Taxonomy is stated in Table 1.  There are three levels of learning in traditional lecture and flipped classroom model of instruction. For remembering learning level, face to face learning happens in traditional classroom while pre-recorded lecture and videos are used for the learning process. For understanding learning level, Question and answer tools are used in traditional classroom and peer to peer discussion tools are used in flipped classroom for understanding learning level.  For analyzing understanding level of learning, homework tool is used in traditional lecture classroom while in flipped classroom, projects and presentation tools are used.   

Table-1. Comparison of traditional and flipped classroom in blooms taxonomy.

Level of Learning Traditional Classroom Tools Flipped Classroom Tools
Remembering Face to face lecture Pre-recorded lectures, reading material and watching video lectures independently
Understanding Question and answer Reflection, Peer-to-peer discussion and collaboration
Analyzing Homework Classroom activities such as group discussion
Applying, Evaluating, Creating Homework or nothing Student projects, presentations and instructor evaluation

Table 2 shows that how traditional and Flipped classroom instructional methods are demonstrated according to the classroom time management stated by Bergmann and Sams (2012). The classroom activities in both traditional and flipped classroom models of instruction are distributed in various time steps. In traditional lecture method, the warm up activity is done for 5 minutes, previous homework is revised for 20 minutes, the new content is delivered for 30-45 minutes and Guided and independent practice and active learning is done for 20-35 minutes. In Flipped Classroom model of Instruction, the warm up activity is done for 5 minutes, Questions and Answering on video lecture is performed for 10 minutes and Guided and independent practice and active learning is done for 75 minutes.

Bishop and Verleger (2013) suggested that the interaction with teacher during learning process is less significant during instructions as compared to real life problem solving based, discussion based, and inquiry-based learning. The Flipped Classroom instruction method exploits on this peculiarity.

1.2. Significance of Flipped Classroom as an Active Learning Approach

The effectiveness of Flipped classroom model of instruction has been proved in many studies as an active learning strategy (Kim, Jin, & Lim, 2015; Park & Park, 2018; Wilson, 2020).  

These studies have discussed flipped classroom as an important part of the paradigm shift from teacher-centered to student-centered learning, in which teachers move the knowledge delivery outside of formal class time. In formal class time, students actively and extensively interact with teachers and peers through collaborative work such as “whole-class brainstorming, group-based hands-on assignments and peer-review, feedback exchange and remedial help” (Missildine, Fountain, Summers, & Gosselin, 2013).
The Flipped Classroom model of instruction highlights the priority of Problems-Solving method over the lecture or traditional teaching method in a classroom. The learning approaches like project-based learning, student-centered learning, problem-based learning and inquiry-based learning emphasize on students to participate actively in the learning process. Most of these learning approaches use Flipped classroom model of instruction (Grant, 2013; Keengwe & Bhargava, 2014).

1.3. Purpose of This Study
A lot of studies have been conducted on the evaluation of the effectiveness of Flipped classroom model of instruction and traditional lecture method, but there is still little unanimity and consensus regarding the most effective methods. The results of previous studies are divergent. There have been many studies including (Bernard, 2015; Chen et al., 2018; Gillette et al., 2018; Hew & Lo, 2018; Miles & Fogget, 2016) which examine Flipped Classroom model as more effective, less effective or making no significance differences. The purpose of current study therefore was to review the previous literature about flipped classroom model and traditional lecture method and to compare the results statistically.

2. REVIEW OF LITERATURE

It has been  a practice that instructors use the traditional lecture method in their classrooms and students follow up lecture with homework (Abedi, Keshmirshekan, & Namaziandost, 2019). The traditional lecture method makes learners passive in getting knowledge as compared to Flipped classroom model as it makes creators. Knowledge becomes viable when there is dynamic participation in the learning process and communications happen between the components of learning practice (Abedi et al., 2019).

Many researchers including (Ash, 2012; Shakibaei, Namaziandost, & Shahamat, 2019) stated that a lot of instructors have moved away from traditional lecture methods. In traditional learning method, the learners are required to just submissively attend and listen to teacher’s lecture and then gather facts from the notes. This method of teaching has been exposed to be unproductive for learners in present era (Abedi et al., 2019; Brunsell & Horejsi, 2013) . Positive results have been stated by those teachers who have assimilated the Flipped classroom model. The Learners were noted to be more active solving the real-life problems (Lai & Hwang, 2016; Roach, 2014). It is stated that students were involved in self-learning procedure in Flipped classrooms model (Sohrabi & Iraj, 2016).

Hew and Lo (2018) conducted 28 revisions equating the flipped classrooms model of instruction to the traditional method of teaching in Nursing. The statistical results show that Flipped classroom model has a 0.33% more significant value than the traditional lecture-based classroom.

Chen et al. (2018) reviewed 46 empirical researches in the field of non-health and health contexts. Their conclusion was that Flipped classroom model has a 0.47% more significant value than traditional lecture based classroom.

Gillette et al. (2018) acknowledged five revisions in the perspective of medicinal education and concluded that there is no significant relation between the flipped classrooms model of instruction and traditional lecture method on last examination grades.

2.1. Flipped Classroom Model of Instruction and Students’ Academic Achievements

In current era, several researches have concentrated on the influences of flipped classrooms model of learning on academic achievements of learners.

Zengin (2017) conducted a research to create Flipped classroom learning environment in Khan Academy and by using an open source mathematical software. The objectives of this research were to inspect the impacts of flipped classrooms model of instruction on academic achievements of students and expose the opinions about the application of flipped classrooms model of instruction. There were 28 participants in research in the subject of Mathematics. The conclusions of the study showed that the flipped classrooms model environment created by Mathematical software and Khan Academy increased students’ academic achievements two times more than that of the traditional lecture method.

Zhonggen and Guifang (2016) directed an investigation to explore the efficiency of Flipped classrooms model on English reading and writing courses by using mix method approach. The data was collected on the bases of satisfaction, a test on Business English course and interview. The results of the study showed that members used flipped classrooms model and scored higher grades than the members taught by traditional lecture method. To demonstrate the efficiency of the flipped classroom Model of learning, Janotha (2016) inspected the level to which flipped classrooms model affected students’  academic achievements in a nursing program. The consequences of the revision exposed that the learners who were taught with Flipped classrooms model scored higher grades as compared to the students taught by traditional lecture method.

A qualitative study about flipped classroom model and traditional lecture method was conducted by O'Flaherty and Phillips (2015). The video lectures were used for the flipped classroom learning process. The results of the study concluded that in flipped classroom model learning strategy, the students achieved higher grades and actively participated in the learning process as compared to the traditional learning method.  

The results of the studies reviewed in this study are illustrated in Table 3 and 4.

The effectiveness of flipped classroom model of instruction has been proved by many studies including (Afzali & Izadpanah, 2021; Bhat, Raju, Bhat, & D’Souza, 2020; Enfield, 2013). The application of flipped classroom model of instruction as a substitute to the traditional learning settings has drawn the attention of instructors and researchers (Johnston, 2017). It is even asserted that the flipped classroom model, which is used to create effective teaching environments at schools, is the best model for adapting with technology (Hamdan, McKnight, McKnight, & Arfstrom, 2013). Studies about the flipped classroom appear in different disciplines including information systems (Davies et al., 2014), engineering, sociology, and humanities (Kim, Kim, Khera, & Getman, 2014) mathematics education (Zengin, 2017) and English composition (Zhonggen & Guifang, 2016).

A review study has been conducted to compare the effectiveness of flipped classroom model of instruction and traditional lecture method. The review of literature and statistical results show that in most of the cases, flipped classroom strategy is very useful for the active learning, student’s engagement, problem solving and students higher order thinking skills. However, there are number of results in which there was no significant difference between flipped classroom model and traditional lecture method has been found.

3. CONCLUSION

A critical comparison of Flipped classroom model and Traditional lecture method has been presented in this study. This comparative review shows that Flipped classroom model is an effective strategy for learning. It increases the self-efficacy of students in comparison with the Traditional lecture method. The main features of flipped classroom model of instruction presented in the literature are active learning method, group discussion, collaborations and problem-solving method. When statistical results are compared between 33 selected articles, the Flipped classroom model shows more significance value in 22 articles and no significance is found in 11 articles between Flipped classroom model and Traditional lecture method. So, it can be concluded that Flipped classroom model is more effective teaching strategy as related to the Traditional method of teaching.

4. RECOMMENDATIONS

In order to be consistent with the results of most of the literature reviewed in this article, the instructor should follow the flipped classroom learning strategy to achieve the high academic performance.
