Resumen: Los futuros docentes del idioma inglés como lengua extranjera deben ser equipados no  
sólo la proficiencia lingüística del estudiante sino también las destrezas necesarias para afrontar el  
desafío de alcanzar altos niveles de motivación y desempeño académico entre sus estudiantes,  
quienes son considerados nativos digitales; desafíos que encontrarán en las aulas de clase del siglo  
2
1. Dichas destrezas pueden ser desarrolladas a través de la aplicación del modelo de clase  
invertida durante sus estudios de pre-grado, razón por la cual el presente trabajo investigativo  
busca explorar diferentes estrategias que pueden ser empleadas para enlazar teorías; tales como,  
las inteligencias múltiples el aprendizaje a niveles superiores y el desarrollo del pensamiento  
crítico, todo ello combinado con el uso de la tecnología dentro y fuera del aula de clases. Se presta  
especial atención a la adaptación de la instrucción acorde a las necesidades e intereses de los  
estudiantes, a los diferentes niveles de proficiencia en el idioma Inglés, y a la promoción de la zona  
próxima de desarrollo con el fin de ser incorporados al modelo de Clase Invertida. De ésta forma  
los futuros docentes aprenderán a través de la experiencia y podrán aplicar con mayor facilidad  
dicho modelo como una práctica efectiva de enseñanza aprendizaje con sus educandos.

Abstract: In teaching English as a foreign language (EFL) to future in-service teachers, instructors  
st  
need to develop not just the students’ language proficiency, but also the necessary skills for 21  
century teaching in the ever changing classroom where pupils are considered as digital natives.  
The required skills future teachers need to accomplish, a higher level in both the students’  
performance and class interest, can be developed through the Flipped classroom model, which is  
why this research work aims to explore diverse strategies that can be applied to blend theories such  
as multiple intelligences and higher order thinking in order to develop students’ critical thinking  
skills through the incorporation of technology outside and inside the classroom. Considerations to  
differentiated instruction (DI), students’ different levels of Second Language Acquisition (SLA),  
and the fostering of the Zone of proximal development (ZPD) of learners are also given as a feature

that needs to be incorporated in flipped classrooms. In real-to-life teaching practice, this offers  
students the possibility to incorporate effective practices that can be directly applied in their future  
classrooms.

Introduction  
Technology has changed the human life in all aspects and education is not an exception. In  
2
000 The American Council on Education stated “the growth of the Internet coupled with a  
growing demand for convenient and flexible access to higher education have brought about the  
greatest change in education delivery since the first correspondence courses were made available  
in the early nineteenth century” (as mentioned by Lehmann, 2004); this prediction has come true  
and it is a reality inside our classrooms. Our students are digital natives, they are familiarized with  
the use of the Internet and all kind of digital devices because they are surrounded by technology  
since the moment they are born (Presnky, 2001).  
The digital generation has also a huge impact in teacher’s instruction and the way how it  
should be delivered. Teachers should be aware that due to the fact that because of the  
“upbringing and experiences with technology, digital natives have particular learning preferences  
or styles that differ from earlier generations of students” (Bennet, Maton, & Kervin, 2007). The  
twenty-first century teacher should seek the development of students’ critical thinking skills, the  
application of differentiated instruction to cater to students’ individual needs, and the  
incorporation of technology to the class in order to prepare learners to be successful in their  
current and future lives. The teaching of English as a foreign language (EFL) also has to prepare  
future in-service teachers to match this reality by incorporating these instructional features as  
effective teaching practices for their future classrooms. This creates a need for EFL instructors to  
not only work on future in-service teachers language proficiency, but also work on the  
development of teaching skills that incorporate the use of technology in class delivery in order to  
meet digital native learning needs; thus, making the implementation of flipped classroom in this  
area worthy of consideration.  
Flipped Classroom  
The pioneers of this teaching model were two teachers from a high school in Woodland  
Park CO, United States of America. Jonathan Bergman and Aaron Sams were concerned about  
students who missed classes in order to attend sports competitions or other events. For that reason,  
they decided to record their Chemistry lectures by using screen capture software that were later  
uploaded as videos to YouTube. In this way, their students could download the lectures and watch  
them at home whenever they wanted and as many times they needed it. The students were  
benefitted with a better understanding of the content. Since 2007, this teaching model has been  
applied by many teachers around the world. (flippedclass, 2011)  
A flipped classroom is defined as a class where “students are required to use web resources  
as homework and undertake initial instruction of the lesson content themselves on new topics,  
while the class time is used for interesting laboratory explorations or practice activities using the  
new content” (Bender & Waller, 2013, p. 80). In other words the traditional model where the  
teacher explains the new content to the students inside the classroom and gives reinforcement tasks

to be developed at home is changed for a model where the teacher becomes a facilitator of learning  
by monitoring classroom activities and by reinforcing and building upon the concepts that the  
students have already reviewed at home. The leaders of the Flipped Learning Network (FLN)  
highlight the difference between flipped classroom and flipped learning. They state that teachers  
can flip their classroom by sending students to read at home or watch educational videos but it  
does not necessarily means that the learning is being flipped. FLN states that a flipped learning  
should be based in the four pillars of F-L-I-P “flexible environment, learning culture, intentional  
content, and professional educator” (Flipped Learning Network, 2014)  
The first pillar flexible environment involves differentiated instruction through considering  
our students learning styles and multiple intelligences during the instruction and assessment. The  
second pillar is the learning culture which considers the student as the center of the instruction.  
This pillar is based on the constructivist approach for that reason the classroom time is used for  
students to analyze the topic in depth and to work with the teacher and partners to understand and  
take ownership of the content in meaningful ways. The third pillar is the intentional content. It  
guides the teacher to decide which content should be taught in the classroom and which content  
can be managed by students at home. Finally, the fourth pillar is the need of professional  
educators. It involves the critical reflection from the teacher of his teaching practice. It is the  
sharing of educational strategies with other teachers and the acceptance of criticism in order to  
improve instructional practice. It is the searching of teaching tools that best fit their students’  
needs. (Hamdan, McKnight, McKnight, & Arfstrom, 2013) . In other words, flipped classroom  
and flipped learning are correlated but they are not considered interchangeable terms.  
Literature Review  
Despite the fact that this teaching model is innovative the research done so far  
demonstrates the effectiveness of using flipped classroom in teaching different subjects.  
Schwankl (2013) conducted a study to measure the effects on achievement and students  
perception of flipped classroom in a rural southwestern Minnesota school. The sample involved  
two groups, one control and one treatment group. The students were enrolled in Integrated II  
Mathematics classes. The participants were freshman and sophomores students and one junior  
student. The researchers applied pre-tests and post-tests to both groups. The treatment group  
received classes by applying flipped classroom model; the teachers recorded the lectures by  
using Screencast-O-matic and then they uploaded the videos on Youtube, the teachers also gave  
the students the option to access to the recorded lectures by using a flash memory. The students  
were required to watch the videos at home and develop assignments and learning activities  
during the classroom’s time. The control group received classes by using the traditional  
instruction. Both groups studied the same content during the research period. The total score in  
the post-tests reflected a higher achievement of the treatment group (5.54%) over the control  
group (1.81%).  
Pearson (2013) reports how the flipped learning model dramatically improves course  
approval rates for at-risk students in the Clintondale High School in Clinton Township, Michigan  
in United States of America. The participants were 32 teachers and 553 students. In 2010, the  
high school implemented Flipped Classroom for teaching Math, Science, Social Studies, and  
English Language arts to freshman at-risk students. The teachers created videos of their

classroom lectures and posted them online in order to the students watched the videos at home as  
homework; the classroom’s time was used for educators to work with students on individual  
tasks and to foster collaborative learning through small groups tasks related with the content  
studied by the students at home. The results showed that by the end of the first semester of  
implementing this teaching model the pass rate increased in Math from 56% to 69%; in Science  
from 59% to 78%; in Social Studies from 72% to 81% and in English Language Arts from 48%  
to 67%. In addition of these case studies more qualitative and anecdotal data can be found online  
as support of flipped classroom benefits for teachers and students.  
For the aforementioned reasons, these studies prove the effectiveness of implementing  
flipped classrooms to achieve higher levels of students’ performance and class interest.  
Application  
In order to apply flipped classroom as a teaching model for EFL instruction four aspects  
need to be considered: the sources, the homework, the activities developed by the students within  
the class time, and finally the assessment tools.  
Sources  
When EFL teachers think in the term flipped classroom the first thing that arises in their  
mind is technology. There are two main issues for future in-service teachers to consider  
regarding to technology. The first concern is the students’ access to internet or technology itself.  
It is well known that in developing countries not all students have access to an internet  
connection at home which can make it difficult for learners to fulfill certain tasks assigned by  
teachers. On that regard, teachers should take special attention to enquire about students’  
technology access and ensure taking the necessary measures to overcome students’ limitations to  
perform tasks; for instance, the use of flash memories can be enforced or the availability of  
computers during school time could be allocated.  
The second issue is related to the teachers’ struggle with technology. Despite the current  
importance given to technology in teaching, there is still a big group of teachers considered  
digital immigrants who still struggle with technology. Most of these teachers are afraid to use  
technology as part of their curriculum delivery because they think that it is demanding, stressful  
and difficult to handle. It is important to remark that it is not necessary to have high level tech  
knowledge to address a flipped classroom model. We can find online recording software or  
applications easy to handle. The easiest way is to record the lesson and upload it at Youtube. The  
video can be recorded by using Screencast-O-Matic which is a screen capture software, which is  
available for free to educators. This application gives teachers the option to record just their  
voice and explain what appears on the screen; educators can also include themselves on the  
screen by using a webcam. Educators can use websites, power point or any other tool to explain  
the content of the lesson to the students. When the recording is done teachers have the choice to  
publish the video to you tube or to publish a video file; the second one allows teacher to save the  
video on their computer in the format that they choose in this way the students have the  
opportunity to access to the videos by using internet or by saving the video in a flash memory to  
be watched at home. (Reardon, 2014).

Homework  
According to Bergmann and Sams (2012) educators should observe four stages for  
making the videos that students will watch at home as homework. Those stages are: Planning the  
lesson, recording the video, editing the video, and publishing the video.  
Planning the lesson. Teachers should plan the lesson as they usually do before starting  
with the recording, it is crucial to “determine the objective of your lesson and decide whether a  
video is an appropriate instructional tool to accomplish the educational goal of the lesson”  
(Bergmann & Sams, 2012). Teachers have to use practical wisdom to choose the videos and the  
content of the videos that best fit with the target of the lesson and the National Curriculum  
Standards.  
Recording the video. Teachers have to avoid overacting in front of the webcam. The  
instruction should be in the same way as he was in front of the class. It is advisable to record the  
lessons in a more conversational style rather than formal style because it will foster the students’  
engagement. (Bergmann & Sams, 2012)  
Editing the video. This step can be time consuming but it is necessary because during  
this process teachers can add more information or take out irrelevant information from the video.  
The objective is to “highlight and reinforce what has been said in the recording with a visual cue  
that can aid in students understanding”. (Bergmann & Sams, 2012)  
Publishing the video. One of the most accessible ways to publish a video would be to  
upload it to YouTube. In order to do this, teachers can open a YouTube account and give the  
students the link were they can view the videos. Another option would be saving the videos in a  
flash memory or to burn them on a DVD for students who do not have access to internet. The  
suggestion is “to pick one or two methods that meet the needs of your students and do them  
well” (Bergmann & Sams, 2012)  
As EFL teachers, flipped classroom offers us a world of possibilities by using free tools  
available online for teaching EFL students. These tools can easily meet the content of the lesson  
and our students’ different learning styles for instance “videos can really be a good addition to  
any class, especially for students who may be struggling readers or those who are visual  
learners” (Arntsen, 2014). Visuals will help our students have a better understanding of the  
content. Tools that can be used for EFL teachers are available online, for example the Learn  
American English Online site offers students resources that include readings and tasks to  
improve English grammar and vocabulary acquisition. It includes content for different levels of  
Second Language Acquisition (SLA). According to Lowe (2014) “the website is a great resource  
in a “flipped classroom,” because it allows students to preview a grammar point at home before  
coming to class to practice the use of the grammar in communicative activities”. This preview  
grammar knowledge can be used to develop listening and speaking skills during the class time.  
Class Time Activities

Flipped classroom is a student-centered model which is related with the differentiated  
instruction (DI) approach. DI allows teachers “to develop lesson plans and activities that keep  
children from being left behind or waiting to move on” (Heacox, 2012), it gives educators the  
opportunity to meet their students’ needs. It takes into consideration the different levels of  
Bloom’s taxonomy to promote the student’s development of higher order thinking skills while  
also giving attention to the different multiple intelligences found in the classroom. In addition,  
flipped classrooms create a class ecology where the use of the Zone of Proximal Development  
(ZPD) theory becomes a main staple to foster students’ scaffolding of knowledge.  
According to Gardner (1983) there are eight ways in which people learn and he called  
them intelligences, they are: verbal/linguistic, logical/mathematical, visual/spatial,  
bodily/kinesthetic, musical, interpersonal, intrapersonal, naturalist and existential. (as  
mentioned by Garcia, 2004) Each one of these intelligences has different characteristics and EFL  
teachers can use diverse strategies in the class time to reinforce learning and monitor students’  
development of language skills. Some strategies are suggested in the table below.  
Table 1

initiative_09.06.06_u  
Other strategies that can be used in class time are related to Bloom’s Taxonomy of  
Educational Objectives (Bloom, 1984). Bloom presents different levels of thinking that students  
have to develop to reach meaningful learning. Using the flipped classroom model “tasks are

scaffolded to align with Bloom’s Taxonomy and build student understanding of the text”  
(Bretzmann, 2013). Each one of the levels assist learners in developing higher order thinking  
skills by doing class time assignments that encourage students to go beyond the prior knowledge  
they reviewed at home.  
Figure 1 shows what levels are covered by the lesson videos (homework) and what levels  
should be covered in class time. EFL teachers can apply different strategies for incorporating  
Bloom’s taxonomy in flipped classrooms, for instance students can work with graphic organizers  
for developing reading and comprehension skills.

https://www.iste.org/explore/articleDetail?articleid=14&category=In-the-  
classroom&article=4+learning+strategies+that+make+the+most+of+flipped+learning  
EFL teachers should also take notice of the activities that can be developed in each one of  
the thinking levels and different types of graphic organizers that can assist on reaching that level  
objectives. If the students have access to computers or iPads in the classroom educators can use  
online tools to create graphic organizers or visual products; a suggested free tool to be used is  
EFL teachers are aware of the importance of interaction among students in order to  
develop language skills. Flipped classroom allows teachers to mostly use the class time to foster  
these interactions. The ZPD theory (Vygotsky, 1997) states that through collaborative learning  
people can understand content, they can achieve tasks and they can solve problems in a level that  
they would not be able to reach individually. Figure 2 explains the four stages of ZPD.  
During class time teachers become a facilitator of learning by grouping students to  
accomplish a variety of activities and by monitoring the process and giving feedback and  
reinforcement when necessary. On their work Bergmann and Sams (2014) quote an anecdotal  
teacher’s experience with flipped classrooms:  
In traditional classroom, students spend the precious time they have with the  
teacher listening, as opposed to interacting. The flipped classroom flips the focus of the

teacher to the students. I believe it offers students more down time to really practice,  
learn new concepts, and later on master them. (Bergmann & Sams 2014).  
Figure 2. Model of four stages in the zone proximal development by Gallimore and Tharp, 1990.  
Assessment Tools  
Flipped classroom allows educators to apply formative assessment assigning in-class  
activities to students or assigning different activities to be accomplished out of class time. EFL  
teachers can develop assessment tools that blend the different levels of SLA with the diverse  
multiple intelligences. For instance to evaluate the students accuracy of applying new vocabulary  
words about the lesson “occupations”, EFL educators can apply activities suggested in table 2.  
The activities described can also be done by using technological tools if they are available  
for the students in classroom. The teacher can grade the assignment by applying rubrics which  
should be explained to the students in order to have a better understanding of the tasks’  
objective. The learners can choose what activity they will develop as assessment according to  
their English language level and learning preferences. Feedback can be send via email to the  
students and parents.

Conclusion  
Technology has changed the traditional teaching and educators are conscious about this  
fact. Flipped classroom is starting to be a reality in classrooms everywhere and EFL future in-  
service teachers need to be ready to cater to the needs of highly digital learners through this  
novel teaching model. The benefits of flipping the classroom are many. It allows the opportunity  
to apply differentiated instruction that is palpable for students inside the classroom because the  
content is delivered at home and the class time is used for reinforcing and monitoring. Diverse  
strategies can be applied to blend students’ multiple intelligences with the different levels of  
higher order thinking from Bloom’s taxonomy. Also the teacher can differentiate the teaching by  
grouping the students in their different levels of SLA and by fostering the ZPD of the learners.  
Despite the fact that this teaching model is rather recent the research and the experience of many  
teachers support its application on different subjects. The results that can be achieved regarding  
students’ motivation and performance make the flipped classroom model a tool worthy of  
consideration for teaching English as a foreign language.
