Nowadays, the expansion of new technologies in developed countries requires their inclusion in the higher educational systems, focused on the development of new skills to promote a continuous and independent learning process for the students. Internet technologies have reached a wide social diffusion, mainly among young people, and therefore the use of digital technologies at university, from smartphone apps to online collaboration tools, is becoming more and more embedded. This article describes the exploration of using wiki to promote the study of a degree in Pharmacy, particularly in the area of Pharmaceutical and Organic Chemistry, by creating a collaborative network that encourages group interaction instead of individual achievement. Our initiative is aimed at developing a number of skills and abilities of students and improving their academic performance and their comprehensive training. This work has been carried out with students, who followed Pharmaceutical Chemistries I and II, compulsory courses of the degree in Pharmacy, and it has been extended to other compulsory (Organic Chemistry II) and optional courses (Advanced Chemistry of Drugs), for a total of 200 students. Students have worked in teams on topics related to the subjects above indicated and have used wiki to develop their work. Opinion polls have shown a degree of satisfaction between high and very high in their performance, highlighting the benefits of using wiki in learning.
KeywordsStudents’ learning Wiki Collaborative network University education Web 2.0
The use of technological tools on learning, such as online collaboration tools, presentation software or online course materials, has achieved widespread social dissemination (Tapscott, 2009), especially among young people, inviting the search for possibilities to improve teaching and to achieve the proposed educational objectives. The update on the university education system, due to the adaptation to the European Higher Education Area (EHEA), implies new demands on teachers (Curaj, Matei, Pricopie, Salmi, & Scott, 2015). The creation of this area poses significant challenges, mainly derived from the change in the approach to the educational process. It has passed from teaching based on the transmission of knowledge and configured around the professor to a student-centered system, and to develop skills which enable them to perform their future professional work in the most appropriate way, as well as to facilitate their integration into the labor market system (Pérez Ríos, 2003).
We are now in a situation where the educational request is demanding and diverse, so it has been necessary to incorporate technologies for learning into teaching. This is what is known as e-Learning (Bichsel, 2013; Rosenberg, 2001). The development in recent years of new trends on the Internet, together with the concept of Web 2.0, has given rise to the need to move their application to education with the confidence that their characteristics contribute to achieve some of the goals set by the new system (Boza, 2009; Moreno, 2011). By using these new technologies (blogs, wikis, social networks, etc.), users do not behave as passive users only receiving the information, but they go on to become active members participating and contributing to edit that information.
In the last decades, emerging technologies, as this case work, have been introduced to both traditional classrooms and online courses, increasing motivation and facilitating the interchange of knowledge and expertise among students (Wankel, Marovich, & Stanaittyte, 2010).
Wiki is a tool that can facilitate social interaction and collaboration, and this technology can be used to create a student-centered collaborative learning environment (Ruth & Houghton, 2009; Augar, Raitman, & Zhou, 2004; Hu & Johnston, 1990). In this way, wiki is a website where a group of users can create, write, delete or change the content of a web page by easy and rapid interactivity. Wiki can also facilitate collective and constant review and the possibility of periodically extending the content and activities, essential in a learning process (Lipponen, 2002).
The use of such technologies is significant in teaching different subjects of the Degree in Pharmacy, such as Organic Chemistry and Pharmaceutical Chemistry. On the other hand, classes usually have a large number of students making it difficult to ensure effective verification of their work.
In this sense, this paper describes our experience and research based on the use of a wiki to help better understand the contents of these subjects. This Wiki could ease the exchange of ideas, motivate the students and promote their interest in the subject as well as facilitate the review of the students work by the instructor.
This initiative was developed over two academic years and carried out in different subjects of the Degree in Pharmacy. This involved Organic Chemistry II (second year), Pharmaceutical Chemistry I (third year), Pharmaceutical Chemistry II (fourth year) and Advanced Chemistry of Drugs (fifth year), a total of 200 students. Students, whose participation in the use of a wiki was optional, have worked in groups of 2-3 people, on topics related to the subject and have used a wiki to develop their works. For example, they had to explain and review a scientific article related to a particular topic, or had to solve a synthetic route of different compounds with therapeutic activity based on knowledge of organic chemistry. Then, they had to expose their work done.
Informational meetings about the use of wiki in university teaching, so that students know clearly the tool that will be used to share their knowledge within different subjects of Pharmaceutical and Organic Chemistry.
Making a private wiki for collective learning in “wikispaces.com” by the administrator (teacher), and including students of the different subjects as group members.
Offering students topics and scientific articles related to the subjects to perform their works in group through wiki, to promote teamwork and collective intelligence. This aims to help students to understand better and assimilate the bases and contents. Students would work in each topic using wiki, sharing information with their peers through it, making their tasks and modifying in real time their work without the need of a physical meeting.
Oral presentation of the work done through wiki, aimed at helping students to gain a better understanding of the theoretical contents of the different subjects.
Self assessment by opinion polls of both the acceptance and the impact that this wiki has had on students who have used it.
The second section (Fig. 2) included four issues about the results achieved after using this tool. It seeks to check if the set time is enough to carry out the work, if the wiki really enable more contact with the teacher and colleagues or it helps the students to improve other skills. In these two sections, to answer the questions, participants had to choose one of four grades: low, intermediate, high and very high.
In the third section (Fig. 3), and through three questions, students were asked if they previously used the Wiki, also about the improvements they consider appropriate to perfect the wiki and its possible utility in the future.
Finally, the fourth part of the questionnaire was evaluated by the students also with four levels (low, intermediate, high and very high) to find out their overall rating (Fig. 4), regarding the initiative of using wiki and their involvement in this experience.
The questionnaires were collected at the end of the term. Once the survey data were gathered, all analysis was conducted with the SPSS version 15.0. Graphs were carried out to illustrate the results obtained.
The purpose of this initiative is to develop a range of skills and abilities in students to enhance their interest for the subjects by promoting group interaction instead of individual achievements and motivating them in order to improve their academic performance and comprehensive training.
Internal evaluation and instruments
The assessment of this experience was made to the students who participated as volunteers by opinion polls. The results are discussed in the following four areas and are showed in Figs. 1, 2, 3 and 4.
Students opinion on the usefulness of the Wiki
Regarding the usefulness of Wiki in the teaching process, 37 % of the participants qualify it as intermediate and 48 % as high. This data indicates a wide acceptance of the method and implicitly an additional positive contribution that could be reflected in different levels. Thus, 52 % of users think that the use of this tool promotes and encourages the teamwork since the work was carried out in groups without the need to be physically. Furthermore, the majority of students consider that they have acquired greater relevance and role in the learning process with their own contributions, contents and active participation (Fig. 1). Also they believe that the knowledge acquired through the teamwork development could not be learned in the normal course of the subject since only 8 % indicates otherwise.
Respect to the handling of the Wiki, the vast majority believes that this tool is easy to use and to add contents to it (25 % intermediate, 38 % high, and 31 % very high) which was reflected in the fluency work and the few technical difficulties. 30 % and 14 % of students chose the high and very high option to indicate that the Wiki enables the expansion of the knowledge, discovering other aspects of the subjects like the research field and, not limited to the basic knowledge given in class. Finally, a very high percentage of the participants recommends the use of this method in other subjects of the Degree in Pharmacy and even incorporate it into more degrees.
Student opinion on the communication and value of the Wiki
Seventy-seven percent of students think that the time to carry out the work has been adequate (53 % high and 24 % very high). In the set time, students had to read, understand, discuss and point their observations, opinions and reviews about scientific papers and works proposed by the instructor. Then, they had to prepare an oral presentation on the topic. In addition, a great number of students states that Wiki enables more contact with their teacher and classmates due to the discussions generated about the topics covered, which improves relationships between peers and provides a good study environment (Fig. 2).
Moreover, almost 60 % of students (between high and very high options) consider that the use of Wiki and the oral presentation of work done contributed to improve other skills, among which the enhanced use of tools, learning the use of the page, managing specific programs for organic synthesis, or understanding some synthetic mechanisms in order to better assimilate the subject.
Student opinion on how the use of the Wiki could be improved
Students consider adequate the use of Wiki since only 8 % of them would change some aspect in the development of the work done such as for example, to have more time for the preparation and presentation of work, while 66 % believe they would not change any aspect, and 26 % are indifferent (Fig. 3a). Besides, 76 % of participants think that Wiki is useful to be reused in the future (13 % very useful and 63 % quite useful), others believe that their usefulness is limited (22 %) or not useful (2 %) (Fig. 3b). Finally, most of them say they have not used this platform previously (94 %), and only 6 % have used it ever (Fig. 3c).
In general, the score of this initiative was quite satisfactory since only 1 % of the students who have participated gave a low score, while most users qualify as high (66 %) or very high (11 %), both the tool itself and the acquisition of knowledge through it (Fig. 4a).
As for involvement in this experience, 82 % gives a high and very high score, and only 17 % an intermediate one (Fig. 4b), indicating that Wiki environment has been well accepted by students being useful to improve their learning process.
Evaluation of student learning
The evidences discussed in this section regarding student learning are based on the observation of lecturers and their personal appreciation of the evolution after using the Wiki in teaching. They suggest: Firstly, an increase of the users’ motivation by issues related to Pharmaceutical and Organic Chemistries, resulting in a greater understanding of the theoretical contents reflected in improved exams marks. In addition, students increased their relationship with their teachers, as they need to solve questions related to the use of this tool in the work performance. Furthermore, an improved relationship among students has been noticed, as they should develop their work and solve problems together, agreeing on how to synthesize and transfer the work into the offered literature.
On the other hand, students have improved collectively their capacity of understanding, synthesis and presentation of the results. Also, an increase of students’ interest in the work performance by using these new tools applied to teaching has been perceived. In addition, their critical capacity to be able to conduct the review and correction of issues uploaded to the platform by peers has been enhanced. Finally, an increase in the discussion, debate and communication between students has been observed along with the ability to take decisions together.
This project has created a collaborative work platform on the web, which allows both teacher and students, to work together, which has promoted the collective intelligence and the exchange of ideas with improvement in the teacher-student relationship. In this way, an alternative learning method has been developed that allows a better integration of lessons, seminars and performance of works proposed by the teacher. In addition, as have been illustrated in the survey results, this initiative has led to a greater motivation of students for the acquisition of knowledge by using simple methodologies, and their critical capacity has been promoted, reflected in a better academic performance.
The ability to work independently, remote (on-line), at any time, from different computers without any meeting.
Increasing interaction, not only between partners of the same group but also among colleagues from different groups.
The encouragement of the student participation closer to the teacher.
Learning to use a new platform and accommodating the use of this new intuitive technology.
The ability to know the development of the work and changes made by peers.
Learning to better expose in public.
Increasing interest in the subject and knowing concepts that are not taught in class.
The use of a new tool unknown for most of the student.
The difficulty of understanding scientific texts in English, which sometimes affects the well development of the work.
In summary, a new tool has been learnt by students that can be useful for them in the future. They have increased their knowledge beyond the theoretical programme of the subjects, enhancing their academic yield. This method has improved collective and constant review by teachers and students. The performance of tasks has helped to understand better the theoretical contents of Pharmaceutical and Organic Chemistries as well as other skills related to it, such as the ability to synthesize and to expose in public. Wiki’ flexibility and simplicity have been demonstrated as a platform that helps to improve student learning and to increase the diversity of perspectives while maintaining quality. The use of Wiki platform encourages students to learn about collaborative processes and fosters a sense of community, instead of an individual achievement as in a traditional competitive assessment.
Finally, opinion polls have shown a degree of satisfaction between high and very high on their performance, highlighting the benefits of using Wiki in the learning process.
