        <p>Universitat Politècnica de Valencia is devoting a large scale effort in applying Flipped Learning to University's courses. For that there is a program that both encourages and support teachers in this educational technique. The program has been carried out as a pilot in two semesters of the academic term 20142015 and as a production service in the ongoing academic term 2015-2016. So, by participating in this program teachers can choose between different kinds of Flipped Learning implementations, some use video as a learning tool and some don't. This has allowed us to make a comparison between the ways students use the educational content in both cases. Result shows that students like video as their primary tool in Flipped teaching, and also that video-supported courses get better overall results in the appreciation and engagement from the students.</p>

      <p>
        The Universitat Politècnica de Valencia (UPV) is a higher education institution with a
strong history in applying IT technologies to learning processes. Beginning with the
campus-wide LMS deployment in 2002, and then with the learning objects production
with the “Networked Teaching” project, the development of the Polimedia system [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ],
the Videoapuntes lecture recording system [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ], and in the last years the integration of
automated transcription and translation systems. Also the production of MOOC
courses, being an active member of the edX consortium.
      </p>
      <p>While these programs have had a remarkable success in terms of the amount of
learning materials, their quality and the students’ opinion, they have been mainly used in a
blended-learning system, in which classical lectures are complemented with those
learning objects. In other cases, as in the MOOC courses, that material has been used
also to create complete online courses.</p>
      <p>
        However, recently a new paradigm in pedagogy has been developed: Flipped
Learning (FL). In Flipped Learning [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ] [
        <xref ref-type="bibr" rid="ref4">4</xref>
        ] there is an inversion in the classical lecture system
so that students receive in advance the theoretical content that they used to receive in
the lecture hall and the time in the lecture hall is used to clarify, reinforce and practice
the subject they are studying.
      </p>
      <p>
        By applying FL the learning environment moves from student-centered to
teachercentered. As Bishop proposes in [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ], in the student-centered classroom, students share
responsibility for their learning and become more engaged in the learning process. This
typically means that students are introduced to contents prior to class in order to then
practice what they have learned in a guided setting.
      </p>
      <p>The popularity of the flipped, blended, or hybrid classroom has grown rapidly in
recent years, due in part to the understanding that traditional methods of instruction are
not always the most successful. Although teachers in traditional classrooms often work
to differentiate lessons for students of different levels of interest and ability, it is
difficult to help every individual student find his or her way.</p>
      <p>This paradigm requires a change in the functions of the teachers, but also a
production effort having that teaching materials before the assigned time in the lecture hall.</p>
      <p>Following this idea UPV developed a project to both encourage and help teachers to
join the FL methodology, and also to verify that the results presented in other
experiences were, or not, applicable to its particular conditions. This project began as a pilot
in the academic term2014-2015 and is fully deployed in 2015-2016. During this time,
several evaluation have been carried out, and we have obtained valuable data.</p>
      <p>The objective of this paper is to present the experience and investigate the
differences between video supported FL and non-video supported FL in the ongoing
academic year 2015-2016. To do so the paper is structured as follows: In section 2 we will
briefly review the related work about FL evaluation. In section 3 we will describe the
experience for this year, and the available data from it. Section 4 will be for the analysis
of that data and finally section 5 will be devoted to conclusions.

      <p>
        There have been quite a number of papers evaluating flipped teaching experiences,
but as far as we have found there is no comparison between video supported FL and
non-video supported FL. As a broad reference, Bishop et al [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ] did a survey of 24
studies related to the flipped classroom, with the characteristics of each of those
experiences, including the study type, sample size, measurement instruments, theoretical
framework, in-class activities, and out-of-class activities. While this is a great
reference, Bishop didn’t consider non-video supported FL as a real experience, so this
research lacks in that part.
      </p>
      <p>
        In [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ] Amresh et al. study the improvements of Computer Science abilities in a CS1
course. A correlation analysis between computing self-efficacy and students'
perceptions of value toward the flipped classroom model was shown to be not significant.
Authors’ suggest that the course improved computing self-efficacy, but that the flipped
classroom pedagogical approach was not the reason for this increase. Authors point to
video length as a key factor in creating engagement for the students. A recent reference
from Guo [
        <xref ref-type="bibr" rid="ref7">7</xref>
        ] supports also that finding that short length videos are a must for a
successful engagement.
      </p>
      <p>Flipped Learning experiences at UPV</p>
      <p>With all these FL activity in mind, UPV feel natural to make a pilot test to know
what would be the challenges and the results of actually deploying Flipped Learning in
a wide scenario of courses. So, for the first semester of the 2014-2015 academic year,
a group of students in two faculties (Computer Science and Business) received all their
courses with Flipped Learning.</p>
      <p>The results of that experience were great in terms of satisfaction of both the students
and teachers, while there wasn`t a significant improvement in the assessment. Those
results were considered enough good to continue the project.</p>
      <p>So, for the 2015-2016 academic term UPV moved a step forward in applying FL to
his courses, by planning a large-scale deployment of more than 100 courses with around
200 teachers involved. Teaching is done on two semesters, and for the first semester 45
courses were flipped.</p>
      <p>In our case we define the flipped classroom as an educational technique that consists
of two parts: computer-based individual instruction before the lecture session and
interactive group learning activities inside the classroom in the time that was set up for
lecturing in standard courses. It’s worth noting that we don’t restrict this definition to
employ videos as an outside of the classroom activity.</p>
      <p>Teachers that apply for the flipped teaching project have a learning session in which
they get the directions to apply FL in their courses. However, while they are encouraged
to use videos they are allowed not to do it and rely in more conventional techniques
like HTML content on the University’s LMS platform or even PDF files. Nearly half
of the teachers decided not to use videos and stick with that semi-traditional approach.</p>
      <p>So we can classify the courses because of why they are distributing the previous
content in 5 different groups, belonging to two main families: video and non-video.
Usually video supported courses also includes HTML and PDF content.</p>

        <p>The 2015-2016 experience, in the first semester, got evaluated 45 FL courses, with
2668 students involved. A summary of courses and students in each category is shown
in table 2.
In order to evaluate the experience we did an anonymous survey to the students of those
courses, divided by courses. The survey included a broad number of questions, some
related to the a priori learning beliefs of the students, some to the overall structure of
the experience and finally on the students’ perception on the value of the FL
methodology.</p>
        <p>The survey is not fully included because of space restrictions. It had 13 questions, in
three groups
1. Questions Q1 to Q4, Q5 and Q12 were included to verify our information about the
course and avoid duplicates.
2. Questions Q6 to Q11 are the valuating questions of the survey. Here is where we can
gather info about the experience
3. Question Q13, with its sub questions, is designed to know the a priori beliefs of the
student, and can help us to identify different learning styles.</p>
        <p>There is some overlap between questions, and we have taken it into account. For
instance, questions Q8, Q9 and Q10 have a high correlation value, which means that we
may use Q8 as a proxy estimator for students’ satisfaction. This data is shown on table
3.
─ Q8 I’m very satisfied with this experience/methodology
─ Q9 I would recommend this experience/methodology to my fellows
─ Q10 I would like to have this methodology in more courses</p>

Beginning with the a priori beliefs, first we look at the question Q13_SQ23: I agree
that I prefer assisting to lecturing than watching online videos (1 lowest - 5 highest).</p>

In this case we can see that there is no a priori preference for video content, apart from
the small PDF group, so we can assume that the satisfaction differences are not based
from sampling problems.</p>
        <p>This can be compared perceived value of the students, the results that we get from
question Q8 by type of content is depicted on table 5.</p>

This table clearly shows a great difference between video and non-video supported FL.
Acceptance rates for non-video are just fair, that means that video should be a must in
considering FL experiences.</p>
        <p>We want also to consider the student engagement. An estimator for that could be in the
sub questions of Q6 After your Flipped Learning experience, show your agreement with
the following assertions (1 lowest - 5 highest):
─ Q00006_SQ001
─ Q00006_SQ002

─ Q00006_SQ007</p>
        <p>I have done the required previous out-of-class work
I have been more engaged on the course
I am happy in this course
I have needed a lot of time to comply with the work of this
Teacher has more time to solve doubts while in class
There is more group work</p>
        <p>I feel well prepared for my final exams
It’s worth noting that all questions but Q6_SQ4 can be considered positive, in the sense
that the higher the better. Q6_SQ4 is negative, so the lower the better.
Here is the correlation matrix for Q6, So, we see that in order to estimate the
engagement we may consider these questions separately.

all students participate actively in the experience (Q6_SQ1), video students get more
engaged (Q6_SQ2), are happier (Q6_SQ3), and require some more time to complete
the out-of-class work (Q6_SQ4). Teachers have more or less the same in-class time
(Q6_SQ5), but in the case of longer videos (Other videos), which also don’t help in
group work (Q6_SQ6). Finally, high quality studio recordings are viewed are the best
in order to be prepared for the examinations (Q6_SQ7).</p>

      <title>Conclusions</title>
      <p>We have presented a large Flipped Learning (FL) experience with more than 2500
students in 45 courses that happened on the first semester of the 2015-2016 academic
year.</p>
      <p>This experience was designed in a way that allowed teachers to choose between
different ways of implementing the FL methodology. Thus we have been able to compare
between those different ways of doing FL, and we have centered our investigations in
the role of video in supporting out-class learning activities.</p>
      <p>The clear conclusion from this investigations is that video supported FL students get
more satisfied and more engaged with a noticeable margin (around 20%), so there is no
sense in trying to deploy FL without video support. Also, small on-purpose videos are
much better that long classical TV documentaries in terms of engagement.</p>
      <p>Also we haven’t found significant differences between the videos recorded by the
teachers themselves and the studio recordings. Our guess is that while the recorded
videos are of more visual quality, they lack the capacity of be changed during the
learning course, so in the Screencast paradigm, teachers can adapt faster to students’ needs.
In any case, this is a topic that calls for further investigation</p>
