Roles and Groups Dynamic as a Systematic Approach to Improve Collaborative Learning in Classroom ()
1. Introduction
Since the establishment of the Bologna Plan in European universities as a referential frame, the proposed methodological approaches have provided an identity marker that focuses mainly on students, their autonomy, their processes of acquisition and construction of knowledge and on them playing active role in their learning (Huber, 2008) . This model based on constructivist teaching strategies has mobilised an important change as it proposes modifying the conceptions and teaching styles of university professors, with respect to teaching based on traditional education strategies (Caballero & Botía, 2015) . Thus, the university system is facing the challenge of proposing a transformation in terms of the teaching-based education model, fostering a new learning-based model, which commits to the profile of an active student who can ask questions, investigate, select and organise information, analyse data, draw conclusions, express themselves adequately, etc. (Rekalde, Martínez, & Marko, 2012) . The methodology based on active learning model can be understood as the generation of knowledge through experimentation (Barros & Ramízez, 2009) . For authors Araujo & Slomski (2013), “the education of future professionals requires skills development, critical-thinking and reflesive ploblem-solving ability”.
Konopka (2015) proposes active learning as a technique that complements the traditional reading by its interactive nature and that teachers apply with the intention of maintaining student interest and creativity.
Fernández (2006) states that teaching methods with the participation of students, where the responsibility for learning depends on their activity, engagement and commitment, are more formative than informative, as they generate a more in-depth, significant and long-lasting learning, facilitating the transfer to more heterogeneous contexts. In this regard, it is important to have an in-depth knowledge of the methodological repertoire and experiment with it to evaluate the possibilities offered by the different strategies in order to adapt them to our needs, with the aim of achieving a learning context that fosters the students’ engagement. The possibility of developing academic and professional competences, developing interpersonal and communication skills, and even changing attitudes are attributed to these methodologies. For Ruiz (2011) active methodologies promote the development of the basic competences of teacher training, and make it possible to dynamically combine attributes related to knowledge, skills, attitudes and responsibilities, thus showing the learning results of a programme, which the students are able to demonstrate at the end of the learning process. Palazón, Gómez, Gómez, Pérez, & Gómez (2011) point out that this type of methodology has a significant influence on the learning quality of these students and on their academic results. However, it must be taken into account that the important part of the methodology used is its adaptation to the learnings and to the intended purpose, considering the competences to be developed, if they used in a technically correct manner and if they are not used as a reaction to each other (Rodríguez, 2011) . Professor López (2005) indicates in his book Metodología participativa en la enseñanza universitaria (Participative methodology in university teaching) that to make the move towards participatory methodology, professors must be trained, not only in positive attitudes and values, but also in new teaching skills that will enable them to help their students change at a cognitive, emotional and attitudinal level. Likewise, the aspects of innovation and renovation are also essential, entailing changes in methodology, ideas, values and beliefs both in professors and students. In any case, as indicated by Zabalza (2003) , the methodological decision teeters on a tightrope, as there are variables that can be changed, but others are sometimes impossible to change.
From the viewpoint of the teachers’ motivation in applying this type of methodology, Lobato & Madinabeitia, (2011) point out that teachers, who are undergoing a learning process in active methodologies through the Eragin programme carried out at the University of the Basque Country, are intrinsically very motivated, and despite the fact that extrinsic motivations are present in this learning process, they are relegated to a second plane. This conclusion coincides with that obtained by Bruinsma & Jansen (2010) who point out that teaching enthusiasm is positively related to the quality of the training programme and satisfactory teaching experiences in the classroom.
After more than one decade of experiences in incorporating learning strategies based on active methodologies applied to the field of university education, it is a good moment to reflect upon the possibilities offered by these methodologies. A review of the most commonly used active methodologies is shown (Table 1).
Given that the majority of the competences to be developed by engineering students have a high practical component and the future exercise of the profession entails situations where they will have to carry out an active role, this type of methodology is adequate in their university education, especially in those subjects where the students express certain doubts about the utility of these subjects in their future professional lives, such as for example, Technical Drawing (Vergara & Rubio, 2013) . These methods permit associating theoretical explanations with direct application in professional situations and real-life (Benegas & Villegas, 2006) . Thus, students

can see for themselves the relationship between certain theoretical aspects and their utility.
The methodology of module projects (Manchado & López, 2012; Serrano, Hernández, Pérez, & Biel, 2013) has been applied since the implementation of the Engineering Degree in Industrial Design and Product Development (GIDIDP) of the University of Zaragoza. Here, students play an active role, associating the knowledge they acquire about the different subjects. The groups and roles systematic approach, presented in this paper, aims to complement the methodological process applied in the GIDIDP, in which an active role of the student is propitiated, increasing the motivation and collaborative learning in acquiring theoretical contents.
This work has been accepted as an Innovation Teaching Projects 2014-2015 at the University of Zaragoza. This experience has involved freshmen (participating in the subject of Artistic Expression) during the first semester. After this pilot experience and obtaining the necessary feedback from students the methodology has been implemented with some changes and improvements in the 2nd semester with sophomores (in the subject of Graphic Design and Communication) and juniors (subject of Corporate Identity).
The goal of this paper is to show the results obtained after the application of this methodology in the lectures of the subjects from 1st, 2nd and 3rd Degree in Industrial Design and Product Development Engineering at the University of Zaragoza, with the aim of presenting its efficacy, flexibility and transferability to other educational contexts and encouraging lecturers to implement it in their teaching practice. The significance of this paper consists in the presentation of a new active methodology developed by the authors and its viability in the context of other active systematic approaches.
This paper structure is as follows: Section 2 contains the principles of the systematic approach conducted in the experience of working with groups and roles. In Section 2.1, there is presented an example of this methodology carried out in one of the three subjects in which this activity has implemented and paragraph 2.2 presents comparative of methodological application between this three subjects. Section 3 contains the results with the discussion of the work and finally section 4 presents the conclusions of the investigation.
2. Methodological Proposal
The systematic approach by groups and roles is based on a learning of theoretical contents in which the student takes an active role.
The aim of implementing this methodology is to:
・ Associate the contributions of the subject to the field of knowledge.
・ Foster the active participation of students in the teaching/learning process.
・ Get to know the students’ learning difficulties and their improvement proposals.
・ Increase the students’ engagement and responsibility in their learning process and interest in the contents.
The experience has enabled students to perform different activities worked collaboratively. These activities have been put forward throughout the semester and students have been able to develop systemic, instrumental, interpersonal specific competencies assigned to different roles.
The following tasks have been assigned to each one of the roles (Figure 1):
・ Red group: its mission was to detect the difficulties in learning the topic or carrying out the exercises proposed, indicating which concepts required explanation and why they represented a difficulty. In this regard, solutions were invited to help towards understanding. The aim of the activities of this group was for the student to develop instrumental competences.
・ Green group: its mission was to identify the practical meaning of the content dealt with in the subject and detect contributions to the discipline of product design. The aim of the activities of this group was for students to develop specific competences.
・ Orange group: its mission was to propose possible activities in which the theoretical content explained is applied. The objective of this role was to develop systemic competences.
・ White group: this group was divided up and integrated into the meetings of the other groups, acting as moderators whenever needed. During the presentation of results of this role, the type of need that arose in each group was indicated as well as the decisions adopted to solve the problems. The aim of the activities of this group was for students to develop interpersonal competences.
・ Blue group: its mission was to assess the proposals/initiatives proposed by the other groups (red, green, orange and white), as well as indicate if they considered them to be adequate or inadequate, and why. The blue group intervened after listening to the contributions of the rest of the groups. It had 10 minutes to prepare its presentation. The aim of the activities of this group was to develop instrumental competences.

2.1. Example of the Implementation of the Methodology
As an example the organisation and the schedule of this activity in the course of Artistic Expression is presented below. To implement this dynamic the first day of class the students were divided into 5 groups (red, green, orange, white and blue) and assigned a specific role. At the end of each theoretical explanation given by the professor, the groups met for 15 minutes to carry out the actions corresponding to each role. After performing the tasks assigned by roles, the groups presented their results orally.
Table 2 shows the organisation of classroom sessions and the development of the works done during the first semester of Artistic Expression of the Engineering Degree in Industrial Design and Product Development at the University of Zaragoza. The table shows the distribution through roles of Group 11, which comprises 39 students. The table does not include the week of class in which the visit of an expert is received and the subject of color is tackled. After each theoretical explanation by the teacher, the groups met for 15 minutes to carry out the actions corresponding to each role. After performing the tasks assigned by roles, groups reported their results verbally.
Likewise Table 3 includes a summary of comments made by the different groups in which the main con- tributions regarding the design theme products display panels are appreciated. The term display panel refers to media containing relevant information about a product design, concept or idea.
Table 2. Development of the activity at the subject of artistic expression, course 1, group 11.
Table 3. Example of the results of work of the different groups in the issue of product presentation boards.
After the oral presentation in class, students attached the panels with the graphic summary of group work.
The activity has been assessed with a value of 10% over the final mark of the subject and a heading was designed to assess the development of the competences.
2.2. Comparison of the Methodological Application in Different Subjects
Once after the first semester has ended, there has been a reflection on the applied methodology in Artistic Expression and some changes to improve this dynamic and also to adapt it to the realities of the subjects of the second and third year have been proposed. The most important change was to eliminate the oral presentations at the end of each class and to replace them by a joint presentation once the theoretical part of the course has finished. This change has been motivated by the lack of time for presentations at the end of each class and turned out to be positive, since the students have had time to synthesize the results of group work and to present it with the support of panels. At the same time this kind of presentations has served them as a review of contents. This has meant the removal of blue role throughout the course since the last day of class all students have performed it evaluating the work done by themselves and their peers.
To the white role tasks an obligation to present at least 5 proposals of possible test questions was added. This task has forced the students with this role assigned to be watchful throughout the theory class act and not only for the work of other groups. Students indicated that this work made them to review the contents carefully, which helped them to prepare for the theoretical exam.
Table 4 summarizes the changes of the methodology applied in 3 subjects taught in different degree courses.
In the next courses following this pilot experience the methodology will continue to be adapted to the needs of the subjects in which it is applied.

2.3. Questionnaire Design and Students Sample
A questionnaire comprised of four blocks of questions was designed with the aim to discover the following aspects: the level of affability and difficulty of each role, the extent to which the different competences are developed and the students’ perception about the organisation of this activity. The questionnaire includes a total of 37 items and it was completed by a total of 64 students of the Artistic Expression subject, 44 students of Graphic Design and Communication and 37 students of Corporate Identity. This sample is representative for the population of the students enrolled in the subjects. The items have been evaluated in agreement with a Likert 7-point scale, where 1 corresponds to total disagreement and 7 with total agreement. The results obtained are described in the section below.
3. Results and Discussion
The results of the research are presented in four blocks. The results presented below are based on the average obtained from the evaluation of the experience of the three courses.
In the first block, the students’ perception about the level of affability of each role in this activity is studied (Figure 2). Results show that the most pleasant roles were the orange and the green ones with an evaluation of 5.6 and 5.5, respectively. The blue role was the worst appraised with a score of 5.23. In general, it can be observed that all the roles exceeded 5 on the 7 scale, indicating that none of them have been unpleasant.

Figure 3. The students’ perception of the level of difficulty of each role in this activity. D-Standard deviation. Z-Standard score.
With respect to the level of difficulty, students indicated that the blue and green roles involved the greatest difficulty with scores of 4.5 and 4.47, respectively Figure 3. The role that turned out to be the simplest was the white one with a score of 3.87. Results indicate that the group and role activity has average difficulty with values of between 3.8 and 4.5.
From the point of view of skills development (Figure 4) the students perceive that the activity helps them to learn the material, they stand that to prepare the questions for the exam helps them to study the theoretical content of the subject (6.48). They also indicate that this approach allows the development of critical thinking (6.09) and helps to compare the quality of their work from that of other group (6.08). However, the least valued aspect is referred to the fact that observing the difficulties of other groups helps to reflect on the learning process (4.98).
In general, the result obtained by the development of interpersonal, instrumental, systemic and specific competences was homogenous (between 5 and 6.5 scores), positively appraising the activity, and understanding that it helps towards developing these competences.

The students’ perception about the usefulness of this activity (Figure 5), is evaluated with 5.19, and introducing this methodology into other subjects with 4.88. With reference to the organisation of the activity, students considered that the most adequate place to carry it out was the classroom, opposed to the possibility of carrying out the experience on an online platform.
In the evaluation of experience done by the students it has been observed that with the maturity of the students the perception of the satisfaction of having participated in this activity has been higher (Figure 6).

4. Conclusion
The methodological activity of groups and roles applied in the Engineering Degree in Industrial Design and Product Development of the University of Zaragoza (Spain), in the subject of Artistic Expression, Graphic Design and Communication and Corporate Identity, has fostered in students an active role in the acquisition of theoretical contents.
Noteworthy among the contributions of this methodology are: the application of the theoretical knowledge to real problems (green role), the development of analytical (red, blue and white roles) and creative capabilities (orange role), social skills and responsibility towards work (all of the roles).
The changes in the dynamic in classroom made in the different subjects show that it is a flexible and transferable methodology to other educational contexts. Each teacher depending on the subject, the time available and the number of participating students can adapt it according to his or her needs.
Coinciding with Martínez et al. (2007) this experience has shown that it is possible to get the teachers to gradually adopt new teaching methods to deliver their subjects and to get students to participate more actively in their learning. The adoption of this type of methodology entails an increase in teaching dedication to the teaching/learning process. However, the authors consider that it is important to continue motivating the students with new learning experiences that entail actions in which students actively develop the required competences.
The experience described is presented as a new active methodology that is in keeping with current work lines that offer the possibility of improving competences, applying a system that entails students’ active participation.
Naturally, the experience carried out is in an experimental phase and its continuation will permit the improvement of this methodology, both at organisational level and from the viewpoint of tools for its evaluation.
