This is a fairly long blog post, so in case you don’t have time to read it all, the key message is this:

Flipping the classroom is likely to lead to improvements in student performance and reduced failure rates when it is used as part of an overall strategy to create a more active learning environment. These gains are likely to have the greatest impact in classes with less than fifty students.

---

One important question arising from our earlier blog posts, ‘What is the flipped classroom?’ and, ‘Designing a flipped module in NILE’, is whether or not flipping your class will improve student learning. Clearly there must be some evidence to support a flipped approach to teaching and learning, otherwise we wouldn’t be suggesting it, but what is that evidence, and where is it?

At the risk of appearing to concede defeat before we’ve even begun, I would like to start by looking at a recent paper which argues that flipping the classroom does not guarantee any gains in student achievement.

 

Flipping the classroom is neither a necessary nor a sufficient condition to generate improvements in learning

‘Improvements from a Flipped Classroom May Simply Be the Fruits of Active Learning’ is a very interesting paper by Jensen, et al (2015), and it is clear from the title what their findings are. They begin the paper by stating one of the main problems behind many of the claims that the flipped classroom improves student learning, which is that there are normally too many variables that have changed between the flipped and the non-flipped classroom to isolate flipping as the key variable. They note that flipping the classroom usually leads to more active learning taking place (indeed, this is often the reason that teachers want to flip the classroom in the first place), and they investigated the extent to which the increase in the amount of active learning, not flipping, is the key variable.

Jensen, et al (2015) took a class of 108 students and divided them into two groups, one of 53 and one of 55. One group had a flipped experience, the other a non-flipped experience – however, both sessions were very active. The diagram on the left indicates how the sessions worked. The flipped and non-flipped classes were compared with each other, and also with the previous year’s class of 94 students, referred to as the original class. While the content and the underlying structure of the teaching remained consistent, a great deal of time and effort was put into creating additional materials for the flipped and non-flipped classes, which is evident from reading the paper.

As will be clear from the title of the paper, the flipped classroom did not produce statistically significant learning gains or improvements in attitudes to learning over the non-flipped classroom, and neither the flipped nor the non-flipped classroom significantly outperformed the original class. The one area in which the flipped classroom did produce a statistically significant improvement was in final examination scores of low level items (e.g., remember and understand type questions) over the original class.

Regarding these results I think that it is important to make at least two observations. Firstly, it should be borne in mind that the students in the study were high ability, highly motivated students attending a private university at which the average ACT score of students is 28 and average GPA is 3.82. For context, an ACT score of 28 would put a student in the top 10% and a GPA of 3.82 would be between an A- and an A. Whilst not necessarily Oxbridge students, they are solid Russell Group students, the kind of students who “virtually teach themselves; they do not need much help from us” (Biggs and Tang, 2011, p.5). Secondly, the original class appears to have been be a fairly active class already, certainly if judged by the standards set in the definition by Freeman, et al (2014) which we will look at later.

The study by Jensen, et al., did come up with other interesting findings though. One finding (2015, p.8 and p.10) which reinforces the importance of time spent with lecturers was that,

Students “perceived their time with the instructor as more influential for learning, regardless of whether they were participating in” the flipped class or in the non-flipped class … “the presence of the instructor and/or peer interaction had a greater influence on students’ perceptions of learning than the activities themselves.”

Additionally, Jensen, et al., were not dismissive of the potentials and advantages of the flipped classroom, noting (2015, p.10) that,

“If active learning is not currently being used or is being used very rarely, the flipped classroom may be a viable way to facilitate the use of such approaches, if the costs of implementation are not too great. As the research indicates, using active learning in the flipped approach can increase student learning as well as student satisfaction over traditional, non-active learning approaches.”

The claim made by Jensen, et al., that active learning is the key variable is certainly very credible, and, as we shall see, it is increasingly apparent in recent publications that flipping the classroom is a very popular way of creating a more active learning environment.

 

Flipping the classroom is a good way of making classrooms more active

‘The Flipped Classroom of Operations Management: A Not-For-Cost-Reduction Platform’ is a 2015 paper by Asef-Vaziri, and it provides an excellent introduction to the flipped classroom. Additionally, the literature review in the paper gives a good overview of some recent publications on the subject. A wide variety of active learning ideas are discussed in the paper (pp.74-80) and they give a good insight into the practical workings of Asef-Vaziri’s flipped classroom. Right from the outset Asef-Vaziri (2015, p.72) makes it clear that the benefits of using the flipped classroom are because it allows more class time to be spent engaged in active learning:

“Class time is no longer spent teaching basic concepts, but rather on more value-added activities, such as problem solving, answering questions, systems thinking, and potentially on collaborative exercises such as case studies, Web based simulation games, and real-world applications”

Asef-Vaziri’s classes were fully flipped in the autumn of 2012 (141 students) and 2013 (157 students), and the average grades were compared to those of the classes in the spring and autumn of 2011 (both with 160 students) which not flipped. The results were as follows:

	Autumn 2012 flipped classroom	Autumn 2013 flipped classroom
Average grade increase over spring 2011 traditionally taught class	+7.4%	+7.3%
Average grade increase over autumn 2011 traditionally taught class	+11.8%	+11.6%

The improvements in Asef-Vaziri’s students’ grades are undoubtedly impressive, and these high gains are likely to result from the significant amount of time and effort that Asef-Vaziri put into re-designing the course.

What came across very clearly in Asef-Vaziri’s paper is the idea that the flipped classroom offers ‘the best of both worlds’, creating increased opportunity to engage in active learning in ways that are difficult for the traditional classroom (due to lack of time) and difficult for online classes (due to lack of face-to-face interactions).

A cursory glance at a number of other recent publications about the flipped classroom makes it clear that a key motivation for using it has been in order to create more active learning opportunities. For example, in their paper, ‘Moving from Flipcharts to the Flipped Classroom: Using Technology Driven Teaching Methods to Promote Active Learning in Foundation and Advanced Masters Social Work Courses’, Holmes, et al (2015) state that the desire to engage in more active learning was the primary driver behind introducing the flipped classroom.

A number of other papers bear out the notion that flipping the classroom is a popular way of adopting a more active approach to teaching and learning, including: Gilboy, et al (2014); Hung (2015); Love, et al (2013); Roach (2104); See and Conry (2014); Simpson and Richards (2015); and Tune, et al (2013). All of these papers make the connection between the flipped classroom and increasingly active approaches to teaching and learning.

Hopefully the above discussion goes some way to making the case that the flipped classroom is a good (or, at least, a popular) way of creating a more active classroom. We will now look at some more evidence in support of the idea that adopting an active approach to teaching and learning is likely to improve student performance.

 

Active learning increases student performance

Active learning is certainly not a new idea. John Dewey (1902, p.6) knew that learning is an active process, and referred to it as such since the beginning of the last century. Some years later, 112 to be exact, Freeman, et al (2014) published an important meta-analysis of STEM education in which 158 active learning classes were compared with 67 traditionally taught classes. Aleszu Bajak, writing in the daily news site of the journal ‘Science’, summarised the paper as follows: ‘Lectures Aren’t Just Boring, They’re Ineffective, Too, Study Finds’. And Eric Mazur, cited in Bajak (2014), said

“This is a really important article—the impression I get is that it’s almost unethical to be lecturing if you have this data.”

The results of the paper “indicate that average examination scores improved by about 6% in active learning sections, and that students in classes with traditional lecturing were 1.5 times more likely to fail than were students in classes with active learning.” (Freeman, et al, 2014, p.8410) To get a sense of the significance of the results, the authors note (p.8413) that had it been a medical randomised control trial it may have been stopped early because of the clear benefit of the intervention being tested; in this case, the active learning. The authors also note that because the retention of students on active learning courses is higher, and because it is lower ability learners who typically drop-out, the positive effects of active learning could actually be greater than reported because the active learning classes were holding on to a higher proportion of their lower ability learners than the traditional classes. And, good news for Waterside, active learning was shown to have “the highest impact on courses with 50 or fewer students.” (p.8411)

One issue which may be useful is to define what is meant by active learning. For the purposes of their study, Freeman, et al (2014, p.8413-4) adopted the following definition:

“Active learning engages students in the process of learning through activities and/or discussion in class, as opposed to passively listening to an expert. It emphasises higher-order thinking and often involves group work.”

Freeman, et al (2014, p.8410) state that for the purposes of their study the “active learning interventions varied widely in intensity and implementation, and included approaches as diverse as occasional group problem-solving, worksheets or tutorials completed during class, use of personal response systems [clickers] with or without peer instruction, and studio or workshop course designs.”

Other studies about the effectiveness of adopting a more active approach to teaching and learning in STEM subjects include Hake’s 1998 paper ‘Interactive-engagement vs traditional methods: A six-thousand student survey of mechanics test data for introductory physics courses.’ The paper concludes that:

“Comparison of IE [interactive engagement] and traditional courses implies that IE methods enhance problem-solving ability. The conceptual and problem-solving test results strongly suggest that the use of IE strategies can increase mechanics-course effectiveness well beyond that obtained with traditional methods.”

Also of interest is ‘Peer Instruction: Ten years of experience and results’ in which Crouch and Mazur (2001) discuss the positive effects of replacing a more traditional approach to physics teaching with Mazur’s method of peer instruction, an approach to teaching and learning developed in the 1990s which inspired the flipped classroom movement.

Whilst a good deal of the most rigorous and credible quantitative studies into active learning have been carried out in STEM subjects, Hung (2015) makes the point in the paper ‘Flipping the classroom for English language learners to foster active learning’, that,

“it is evident that although the flipped classroom approach has mainly been conducted in STEM fields, its feasibility across disciplines (in this case, language education) should not be underestimated.”

 

Conclusion

It’s important to make clear that this has not been an extensive, rigorous and systematic study of every recent publication on the flipped classroom, so any conclusions drawn must take that into account. Nevertheless, and with this in mind, I think that we can still draw a few conclusions with certainty, and a few more with slightly less certainty.

We can be very confident that:

• Active learning produces statistically significant improvements in student achievement in science, engineering and mathematics.
• Active learning in classrooms of under 50 students produces the largest gains.
• Even a small amount of active learning will produce positive gains in student achievement.

We can be reasonably confident that:

• The positive effects of active learning seen in science, engineering and mathematics will be applicable to other subject areas.
• Lecturers in a variety of subject areas have successfully flipped their classrooms.
• The gains in students’ learning achieved by the flipped classroom are more likely to be a result of increasing the amount of active learning taking place online and/or in the classroom.
• Flipping the classroom is a good way of creating a more active learning environment.

It may be the case that:

• The gains in student achievement produced by flipping the classroom will have a greater effect in non-Russell Group universities.
• Flipping the classroom will have a greater effect when focused at the level of knowledge, understanding and application rather than analysis, synthesis and evaluation.

From the papers looked at, it is not clear:

• Whether there are significant differences in the effectiveness of different types of flipped/active learning opportunities.
• Whether there is an optimal level of student activity online and in the classroom (i.e., is more always better?)
• Whether students from all cultural backgrounds experience similar improvements in performance from the flipped/active classroom.
• Whether students whose first language is not the language in which the course is taught experience additional benefits or disbenefits from flipped/active classroom.

Readers wanting to look at the literature themselves and draw their own conclusions are directed to the further reading section at the end of this blog post, which provides links to many recent papers on the flipped classroom from a diverse range of subject areas.
