1. Introduction
The flipped classroom engages students by delivering content outside the classroom and focusing classroom time on collaborative exercises, question and answer sessions, and other interactive communication [
1]. It is a reversed setting of a traditional lecture insofar as content is delivered online in the first stage, and followed by face-to-face sessions in the second stage. Some authors, therefore, call it an inverted or reversed classroom [
2]. Blended learning combines face-to-face with computer mediated instruction [
3]. A virtual classroom is an online learning environment which is often web-based [
4].
Recent research indicates that a flipped classroom setting is well received by participants because it increases motivation, performance, and learning outcomes [
5,
6,
7]. Since the actual course content has to be delivered outside the classroom, an e-learning component is an essential part of any flipped classroom. The way in which such content is delivered can take various formats, such as video clips, animations, ebooks, and even traditional print media. Whether a virtual classroom outperforms a traditional classroom setting is an open question. The main challenge is to determine differences by having a control group.
Table 1 shows a brief summary of comparisons of the two types. Although various authors have been using different definitions of performance, it generally relates to achieving learning outcomes as specified in the curriculum.
Table 1 gives a mixed picture, which leads to speculation about the advantages of a virtual classroom. This paper will not give a comprehensive meta-analysis on the topic, because it would require a deeper analysis. For example, satisfaction should be differentiated further into convenience and interaction with peers and tutors. It might well be that e-learning is more convenient for participants but lacks interaction.
Table 2 looks at the blended learning research, which shows a more positive picture. Blended learning seems to have a positive effect on both student academic performance and satisfaction. All nine studies reviewed were positive. However, O'Flaherty and Phillips [
7] found in their scoping review of 28 flipped learning studies that there is limited evidence on learning outcomes, and results may depend on the actual subject.
During the face-to-face classroom phase, questions and exercises play an important role in engaging students [
20]. Abdulrahman and Al-Zahrani [
21] provided empirical evidence that a flipped classroom increases student creativity when compared to a control group in a traditional setting. However, the fact that a classroom is flipped does not make it automatically more engaging or creativity-enhancing. Technology is only a means to an end. The instructional approach determines learning outcomes, not the technology itself [
8,
12]. Stöhr et al. [
14] found no empirical evidence that virtual learning environments are better or worse than the traditional type, but that this depends on the learning activities that should train students to develop higher-order thinking skills. For this, they need appropriate instructional approaches supported by modern technology and an originality of teaching methods that create the desired skills for the participants [
20]. This teaching approach can be based on authentic events that students have to describe and later reflect upon in a group setting by applying academic models [
23]. Vaughan [
24] warns, however, not to overburden students by using too many forms of assessment to cover too much material. Students can quickly become overwhelmed with content, feel over-assessed, and forget about key concepts.
A critical success factor is the openness of the instructors. They are often unwilling to change [
25]. Maarop and Embi [
26] observed that instructors are often struggling to design engaging and balanced courses. One reason might be that any change will imply the redesign of a syllabus and a teaching style.
Snelling et al. [
27] suggest a seven-step framework to design and evaluate flipped classes, starting with learning objectives/outcomes, pre-class activities, actual delivery online, and followed by face-to-face and final evaluation. Pre-class activities are important because at the initial online phase the lesser motivated participants may be passive if not supported enough. Green [
28] stressed the importance of engaging in a dialogue with participants in the pre-course phase through blogs and discussion fora.
In summary, there is little evidence to support a conclusion that e-learning performs better than traditional classroom learning. However, a combination of both in the form of blended learning can outperform a single approach, which is supported by
Table 2.
2. Materials and Methods
The Euro*MBA implemented the “flipped classroom” concept more than 20 years ago, before it became a popular term. The program is a postgraduate executive MBA (EMBA) program led by a consortium of six European universities. In 1996, they decided to have a joint blended learning EMBA program with the actual course content delivered online, plus six residential weeks (RW) held once at each campus that serves as a face-to-face meeting place. During the RWs, the students work on projects and collaborative exercises, which is combined with one company visit and some lectures. The whole program lasts two years. On average, students have 10.3 years work experience, and each class ranges between 50 and 70 students representing around 20 different nationalities. The program is organized in trimesters. There are two intakes per year. After two online courses—each lasting for seven weeks—one RW follows.
The content is delivered online using IBM Connections in its cloud version. The system differs from traditional LMS (Blackboard, Moodle etc.) in its specific design. It is a collaborative system similar to Facebook. A course is no longer a highly-structured set of topics, but a community with subcommunities who can communicate with other (sub)communities. The students were highly appreciative of the transition from a more traditional LMS to Connections. Each course, depending on the faculty, may include videos, a blog, a wiki, formative assessments, simulations (Excel), discussion fora, team and individual assignments, webinars, and guest speakers.
The organization of the RWs is done by the partner universities. The content is given as part of the curriculum. We follow the seven-step framework as suggested by Snelling et al. [
27]. Step 1 defines learning outcomes and key concepts. Each course has learning objectives, which are shown in
Table 3.
Step 2 refers to the Implementation Strategy. The setup of this European MBA program is unique in the world. Six universities from five different countries agreed on quality standards. They jointly issue a degree, share profit and loss, and commit faculty to teaching in the program. Teaching (mentoring) hours are part of the overall teaching load at the seconding university. Although all the classes are taught in a flipped manner, we analyze a specific course—International Management—in more detail to present exactly how the course is taught. International Management course introductions are always given at Maastricht University (NL) during the January RW. During an introduction, students will learn about the course’s objectives, assignments, available resources, webinar schedule, and assessment rubrics, which are shown in
Table 4. The final grade is constituted of four parts: an Individual Assignment (IA), a Group Assignment (GA, digital storytelling project), forum contributions, and a final exam, each carrying a weight of 25%.
There is no Step 3 in the form of key concepts and related content that students will need to remember and understand before the commencement of the online class. Step 4, class activities, includes four assessment components. For the IA, the students can choose between a case study, writing their own case study, or a company project. Since they are executive students, they are encouraged to write their own case study accompanied by a teaching note in the form of a caselet between 4–5 pages with three components: the context, the task, and the guide to the task. Around 10 hyperlinks pointing to background information should be provided, including some visualization (pictures) of the problem/task. It is mandatory that all three options relate to at least one course topic. The best cases will be used for future classes, and some are even published. The final exam is also based on a case study, which will be given out during the course introduction. The exam itself will take place at the following RW right after the online course. The whole course consists of seven units. Each unit has one forum question. Students are expected to post four to five thoughtful contributions per unit onto the forum board. Webinars are held every Sunday at 3 p.m. CET to allow students from Asia as well as the Americas to participate. The weekly topic reflects the subject of the current unit and often includes a guest speaker. Students are encouraged to host webinars or at least contribute their own experiences. Besides graded assessments, there are also formative ones. Each day the students receive a MCQ (multiple choice question) that relates to the subject. It also serves as an indicator for what page of the textbook they should be at. Executive students tend to shift the main learning activity to weekends, and may become overwhelmed when seeing many posts on the forum, or having textbook and journal articles to catch up with. Joining a discussion at an early stage or late in the process is one criterion of forum assessment. MCQs should help them to pace themselves.
Step 5—delivering the class—happens online. Executive students cannot leave their jobs and meet face-to-face during the seven-week online course. Interactions happen via webinar, discussion forum, and email. Each forum thread will be summarized by the instructor at the end of the unit. Each unit contains at least one journal article that forms the basis for the forum discussion. The students receive special coaching when writing their own case studies or doing a project as an IA. For the GA, there are subcommunities where students can interact, including virtual meetings. Most communication between students and instructors happens through email. One reason is the time zone difference. However, virtual meetings come into play when there is a more complex issue to discuss, such as writing a case study.
Step 6—linking the post-class activities and the assessment—takes the form of a final exam at the RW and seminars on the topic. It also includes a company visit. RWs last for seven full days starting at 8 a.m. (after breakfast) and finish at 7.30 p.m., followed by dinner, and with a 1.5 h lunch break. During the RW, the concepts taught will be discussed and questions answered if this has not been done already during the online course. This is also the time when peers interact by asking each other questions. For example, when they see each others‘ GAs, they can ask for the rationale, the outcome, or latest updates on what has happened in the meantime. A holistic summary of all GAs has been done and posted online by the instructor. Step 7—evaluation of the class—will be discussed in
Section 3.4, Student Evaluation.
Five classes and a total of 276 (N) students were the sample for this research. Each student was given the textbook called International Management, by Fred Luthans and Jonathan Doh. In addition, each week, they received a scholarly article that fit the unit’s topic. The discussion forum played a major part in the course, and was weighted at 25% of the final grade. As a group assignment, also weighted at 25%, they had to create a real-life intercultural negotiation. There were three parts to this assignment: (1) the realistic story itself narrated as it happened; (2) an interpretation of the story based on cross-cultural and negotiation frameworks; and (3) an assessment (survey) of the actors in the story.
To narrate the story, they had to develop a script, and then make a video or use animation software to bring the actors to life. Not all teams managed to handle the video and animation software, so the option was given to use powerpoint, prezi, a blog, a website and so forth, as long as it could elaborate the story. Stories had to be based on real events that happened to the participants. With an average of more than 10 years work experience, the students had no problem coming up with such authentic negotiations.
Figure 1 illustrates one sample story: in it, a woman accuses an expatriate working in Equatorial Guinea of having promised to marry her. Since he is unwilling to do so, her family kidnaps him and asks for US
$200,000 for his release. When his friends involve the police, the negotiation becomes even trickier because the policeman wants to have his cut.
As a part of the flipped classroom, there were three phases of the course: (1) a pre-course introduction during the RW; (2) the online delivery of content; and (3) another RW. The introduction of the course took place at the RW prior to the seven-week course. It generally lasts half a day. The main idea is to see the lecturer in person, and get a course overview which includes a briefing on the group assignment, which is in this case an intercultural negotiation. The introduction takes place on Monday, so students have the whole week to discuss it face-to-face. A team consists of six students, some of whom shoot videos during the week, while others just draft the rough script for an animation. Each team had to develop six stories i.e., one story per team member. To prevent bias before the group assignment, students were not given any theoretical input. The story was instructed to be told as it happened. Had the students been instructed in cross-cultural management, they might have added some details which did not happen to support an interpretation later. In this respect, it is better that they did not know anything about the theory. During the online phase, they had to interpret the stories in the light of cross-cultural frameworks (especially cultural distance).
Table 5 shows the main indicators that are used to measure cultural distance, and the corresponding authors.
These six frameworks represent the mainstream models to measure cultural distance. Hofstede’s [
29] Cultural Dimensions explain why people from different cultures behave as they do. In its original form, it consisted of four dimensions, but was later expanded to six [
30]. One frequently used dimension to measure cultural distance is ‘Power Distance’, which measures the extent to which less powerful people (for example, an employee) accept more powerful people (for example, his/her superior) [
29]. Trompenaars and Hampden-Turner [
31] built upon Hofstede’s [
29] findings, and based their research on 15,000 managers from 28 countries. They derived five relationship orientations—how people deal with each other—that can be considered Cultural Dimensions. Although having used different terms, the findings are similar. For example, whereas Hofstede [
29] used the term ‘Collectivism’, Trompenaars and Hampden-Turner [
31] used the term ‘Communitarism’ to measure whether someone is part of a group rather than being individualistic. In the project GLOBE, a team of 170 scholars collaborated to analyze 17,000 managers from three industries [
31]. Although they used a different approach, they came up with similar categories to Hofstede [
27]. Hall [
31] divided cultures into low and high context cultures. Higher context cultures generally have a stronger sense of group orientation, seniority, unspoken rules, and tradition [
31]. For example, Japan would represent a typically high context culture, whereas the United States would represent a low context culture. Lesser known are Schwartz’s [
34] Value System, and Triandis’ [
35] Individualism-Collectivism model. All six frameworks are compatible despite using different research approaches and different terms.
Analyzing the behavior of the actors in a story was the third part of the assignment, and it was not graded. Students had to fill in a character description form. Besides Cultural Distance (CD), the students were taught about the concept of Cultural Intelligence (CQ), which is defined as an individual’s capability to adapt effectively to situations of cultural diversity [
36], which was also part of the character description form. The students could also add their own criteria on how to measure CQ after forum discussions. After a broader consensus was achieved, the question was then added to the form.
4. Discussion
Flipped classrooms that foster higher-order thinking skills can come in many shapes and sizes. Letting executive students narrate their own experiences as objectively as possible, and in a second step putting them into a theoretical framework, follows a reform-based teaching approach. Reform-based learning is an extension of the constructivist learning paradigm, which emphasizes critical thinking, problem solving, action learning, understanding, and applications. In this case, we assessed intercultural negotiations. In executive education, the emphasis is on competencies, which are a combination of knowledge, skills, applications, and results. The traditional approach to learning concentrates on knowledge. Most classrooms begin with concepts. Our flipped approach begins with practice. In this example, it is a reflection on the negotiation experience of the participant. This practice is analyzed using cultural analysis and related negotiation approaches. This will lead to competencies in international negotiations. It is a more effective pedagogy for executive participants. As it is designed in this flipped International Management course, it represents a better learning approach for executives, moving from the practical to the theoretical to improve practice.
To let students work on a project without prior knowledge of the subject is advantageous because they focus on the reality of their experience. If students had known cross-cultural theories before, their stories might not have been authentic.
The flip side of the online class can be in form of RWs. Evaluations shows that six RWs are highly appreciated. They can take place at one location or at different ones. Although not academically relevant, appropriate logistics should be in place. The findings show low satisfaction with food. Such small things may add to the overall impression and lower or increase the motivation of the participants.
The flipped classroom is a demonstration of the reform-based approach. Is this paper, which considers a course in international management in an executive MBA, the flipped classroom is based on the experience of a wide range of management professionals in international business negotiations. Based on this experience, they developed digital stories which distill their real understanding of what took place in the actual negotiation.
Using the digital stories, executives apply cross-cultural frameworks to specify the cultural distance of the partners involved in and related to the negotiation process. They recognize the importance of cultural intelligence to the negotiation’s success. Most importantly, these executives develop competence in the negotiation process, which relates to successful outcomes.
The informal class dimension of the flipped classroom takes place in RWs. In this phase, the emphasis is on the discussions of frameworks, theories, methodologies, and negotiation approaches that enhance the understanding of the executives’ past experience in international management. This learning process prepares them to be better international executives in the future.
This is the power of reform-based learning and the flipped classroom implemented in executive education. It is a combination of practice and theory, which improves the performance of executives in the accomplishment of learning objectives, and the assessment of those objectives for which executives demonstrated very positive results. In the open-ended comments in the course evaluations, they indicated very favorable responses to the reform-based approach to learning practice and related theories. They appreciated the impact of the course on their professional development.
The methodological limitations of this paper are that it is an actual course in an accredited MBA program. As such, there are requirements in the design and evaluation of the course which limit research potential. Analytically, our paper emphasizes more descriptive approaches because of the journal’s perspective. In another study using the same data base, a sophisticated data mining and content analysis has been applied.
In summary, the reform-based learning approach, as implemented in the flipped classroom, is extremely effective for executive education. The future challenge will be the customization of reform-based learning to cater for the needs of each individual executive without compromising learning outcomes [
