What I learned was a lot more than how to be a base group supervisor, by Shadi Jafari

When I began my occupation at Linköping University, I frequently encountered discussions about problem-based learning (PBL). Despite the abundance of information surrounding PBL, I lacked both a comprehensive understanding and practical experience with it. Even my colleagues’ explanations, though insightful in outlining the purpose of PBL, did not equip me adequately for the role of a PBL group tutor. However, being assigned to be a PBL tutor provided the necessary motivation to enroll in a PBL course, a decision that I am now exceedingly content with.

I consider myself fortunate to have started my tutoring journey with a PBL group while simultaneously undertaking the course. This arrangement afforded me the unique opportunity to put the knowledge I acquired into immediate practice. I also came up with numerous ideas on how to effectively manage the group for optimal outcomes. Furthermore, my experience has inspired me to apply the insights gained from the course to enhance my lectures and laboratory sessions, ensuring that my students derive maximum benefit from my classes.

PBL stands apart from conventional teaching methods by placing a significant portion of the learning responsibility squarely on the student’s shoulders. To support students in this endeavor, base group meetings play a pivotal role. Each base group comprises a few students and serves as a forum where students collaboratively tackle problems through various scenarios. Subsequently, they embark on individual journeys to seek the knowledge needed to address these problems, drawing from resources outside their base groups. In the subsequent base group session, participants engage in discussions and reflective exercises centered around their newfound knowledge. Based on my observations, this arrangement results in a unique sense of accomplishment and satisfaction in students, very similar to the feeling one has after solving a complicated math problem.

The role of the supervisor within the core group is diverse. Their primary goal is to foster learning, as opposed to conventional teaching methods (Nielsen & Danielsen, 2010). What I’ve learned from this course is that as an educator, my role extends beyond mere facilitation. Students may select their subjects for various reasons, not all of which stem from a pure love of learning and improvement in that particular field. This is when my role as a teacher becomes even more crucial. I must utilize every available method to instill a sense of curiosity and motivation in my students, inspiring them to explore and actively pursue knowledge. It’s at this point that I can consider myself successful as an educator or supervisor.

Another tutor’s role within the core groups is to provide support in the learning process, as outlined by Barrows in 1988. The tutor’s responsibility is to maintain the group’s focus on their tasks, thus assisting them in achieving their learning objectives. Moreover, the supervisor should engage the students on a metacognitive level, encouraging them to reflect on their own learning experiences and fostering a critical approach to knowledge acquisition, allowing them to build their own understanding.

Barrows emphasizes the significance of creating an open and positive learning environment within the core group. It is essential for students to feel comfortable admitting when they don’t understand something and be capable of providing constructive feedback to one another. Barrows describes three phases in the tutorial process. In the initial phase, known as modeling, the supervisor often prompts metacognitive thinking in students to encourage reflection on their learning and problem-solving methods.

As the students become more self-sufficient but still require some guidance to ensure the process runs smoothly, they transition into the coaching phase, which is the second phase. During this phase, the supervisor may need to step in and challenge students to promote progress, ultimately leading to the third phase known as fading. In the fading phase, the group can autonomously navigate the processes, and the supervisor takes on a less active role.

It is crucial for a supervisor to recognize that each core group is unique. What was effective in one core group may not necessarily apply to the next. Additionally, supervisors should regularly assess the phase their core group is currently in and tailor their approach accordingly.

It is imperative that the supervisor provides support to students to ignite their motivation for learning. This can be achieved, for instance, by offering positive feedback when students excel in their tasks. By instilling motivation in students, you can contribute to enhancing their critical thinking skills and fostering a more profound learning experience. It’s crucial to perceive the group as a cohesive unit rather than as individual students. Through the supervisor’s approach, the group can also view the base group as a mutually beneficial arrangement; it’s essential for both giving and receiving within the group. The group should evolve collectively, and it’s essential to remember that the supervisor’s role is not that of a lecturer.

Azer (2005) appears to emphasize the importance of establishing a harmonious group dynamic within base groups. Individuals within the group come from diverse backgrounds and have varying life situations. However, the learning process should be conducted professionally. Therefore, it’s crucial to establish a shared consensus on various ground rules so that everyone understands the expectations. This forms a solid foundation for an effective group. Azer believes that it is important as a supervisor to instill trust, give feedback, support discussions, asks open-ended questions when the students do not progress and encourages the group to have a secretary who writes down what the group arrives at when working on the problem.

Furthermore, being able to analyze the group’s dynamics is essential, recognizing that it comprises diverse individuals who share a common goal—learning. As a supervisor, fostering an open and inclusive atmosphere within the group is crucial to motivating and facilitating deep learning in students. High motivation often leads to deeper learning, and it’s the supervisor’s responsibility to inspire students. Motivation, according to Biggs and Tang (2011), can be categorized into four main types: extrinsic, performance, intrinsic, and social. Understanding these motivation types is crucial because students with different motivations may be present in each base group.

Given the presence of diverse individuals with varying levels of motivation within each base group, the role of the supervisor can be challenging. How should one consider the individual while prioritizing the group’s learning objectives? As a prospective supervisor, addressing varying levels of motivation among base group members is a key concern. The PBL tutoring course has equipped me with pedagogical tools to navigate these complex scenarios. Through role-playing, I’ve gained insights into the responsibilities of a PBL tutor. I know that I won’t start as the perfect supervisor, as excellence takes time and effort. What I can commit to is having the motivation to continually improve as a supervisor for my base group and, occasionally, I may need to gently guide my group, recognizing that strength lies in unity.  I think as long as the base group maintains its motivation and achieves effective learning, I will consider my role a success.

Problem based Learning: Theoretical foundation and evaluation of PBL as a pedagogical method – Shumaila Sayyab

Problem-Based Learning (PBL) is a dynamic and innovative pedagogical approach that has gained popularity and is implemented in several disciplines worldwide, particularly in the fields of medicine and healthcare. PBL represents a shift from traditional lecture-based instruction to a student-centered, problem-driven model. This approach is grounded in several theoretical foundations that emphasize active learning, constructivism, and self-directed exploration.

Theoretical Foundations of PBL

Central to the PBL philosophy is the constructivist theory of learning, in which the learners actively build knowledge through their experiences and interactions with the environment. In PBL, knowledge is not simply transmitted from teacher to student but constructed by the learners themselves.1 PBL addresses cognitive load theory, which suggests that learning is most effective when the cognitive load imposed by instructional materials matches the cognitive capacity of the learner. PBL’s focus on solving complex, real-world problems aligns with this principle by providing learners with authentic, context-rich tasks that engage their cognitive abilities. PBL incorporates social and psychological constructivist principles, emphasizing social interaction and collaboration among students. Learning in small groups fosters discussion, debate, and the co-construction of knowledge. This collaborative aspect is informed by socio-constructivist theories of learning.2

The PBL architecture

The PBL architecture typically involves shifts in three levels of curriculum.3

  1. Content coverage to problem engagement
  2. From lecturers to coaches in tutor role
  • From passive learner to problem solvers in student’s role

PBL begins with the presentation of a complex, open-ended problem or scenario or vignette. This problem serves as the focal point of the learning experience, motivating students to explore and understand the underlying concepts and principles required to solve it. The problem is carefully designed to be thought-provoking and relevant to real-world situations.

Instead of traditional lecturers, PBL tutors act as facilitators or coaches. They provide support, pose probing questions, and help students navigate their learning journey. The tutors ensure that discussions stay focused on the problem and guide students towards relevant resources.

In PBL, the students take on an active role in their education. They are responsible for identifying the key questions related to the problem, determining the knowledge and resources needed to address these questions, and independently acquiring this knowledge. This self-directed approach enhances students’ autonomy and problem-solving skills.3 This allows the students to take the role of active problem solvers rather than passive learners waiting to be spoon-fed.

Often, PBL is conducted in small groups, encouraging collaboration, communication, and peer learning. Within these groups, students share their perspectives, insights, and research findings, fostering a rich exchange of ideas and diverse viewpoints.

This educational approach challenges the learners to build on their prior knowledge and connect it with the existing concepts in solving the problem. The students’ progress is continuously assessed through their reflections on the scenario/vignette, which allow the tutor to identify the gaps in their understanding and refine their problem-solving strategies. PBL encourages experiential learning, where students actively engage with problems, reflect on their experiences, and refine their understanding through iterative cycles of problem-solving.4

PBL methodology evaluation

When thinking about implementing PBL methodology in our teaching context, Marincovich beautifully explains and reminds us that the PBL image of classroom is different where PBL is student centered, with the tutor role as guiding rather than directive and it is process oriented which is different from the traditional classroom with the students sitting in rows, in front of a teacher lecturing them.5 Research on the effectiveness of PBL methodology has yielded mixed findings, with studies showcasing both its strengths and limitations. PBL offers several advantages as a pedagogical method:

  1. Enhanced Critical Thinking: PBL compels students to think critically and analytically as they tackle real-world problems. This fosters a deeper understanding of the subject matter and promotes higher-order thinking skills.
  2. Motivation and Engagement: The problem-solving nature of PBL often leads to increased motivation and engagement among students. Learners are more invested in their education when they can see the direct relevance of what they are learning.
  • Long-Term Knowledge Retention: PBL emphasizes understanding over rote memorization, leading to better long-term knowledge retention. Concepts learned in the context of solving a problem tend to stick with students.
  1. Collaboration and Communication Skills: Working in small groups fosters collaboration and communication skills, which are essential in professional and real-world settings.

On the other hand, despite its merits, PBL is not without challenges and criticisms. Kirschner et al. argued that PBL may overload working memory, hindering the transfer of knowledge to long-term memory.6 In another study, authors have raised concerns about the inconsistency in PBL implementation and the need for faculty development.7 Some of the challenges of PBL include:

  1. Resource Intensiveness: It can be resource-intensive, requiring well-designed problems, trained tutors, and adequate time for group discussions. This may limit its scalability in resource-constrained environments.
  2. Variable Implementation: The implementation of PBL can vary widely, making it challenging to standardize and assess its effectiveness. Variations in facilitation styles, problem quality, and student readiness can impact outcomes.
  • Assessment Challenges: Assessing student performance in PBL can be complex. Traditional assessment methods may not align well with the process-oriented, problem-solving nature of PBL.

In conclusion, PBL is a pedagogical method that holds promise in fostering critical thinking, motivation, and collaborative skills among students. This innovative approach equips students with not only subject-specific knowledge but also valuable problem-solving skills and the ability to apply their learning in real-world contexts. However, it is not a one-size-fits-all approach, and its effectiveness depends on various factors, including the quality of problem design, tutors’ expertise, and institutional support.

The Importance of Feedback or Self-reflection in the process of Problem- Based-Learning, by Maike Schneider

Problem-Based-Learning (PBL) is a teaching approach that originated as case-studies for medical students, to train the appliance of theoretical knowledge to real-world scenarios. Today, PBL is understood as a teaching strategy that relies on self-responsibility and group work, thereby opposing traditional teaching approaches, like, e.g., lectures. As such, PBL can be incorporated into a wide variety of academic areas. This method of teaching has three main goals: to facilitate learning (I), to provide students with a skillset that will allow them to find relevant information as life-long learners (II) and to develop social skills and group-work competence that will prove useful in their future working career (III) (1). One important cornerstone of PBL as a concept is constant evaluation in the form of a self-evaluation or feedback given by peers.

Different types of evaluation or feedback

Evaluation can be carried out in many different ways. For example, self-evaluation is a personal reflection of the own performance while peer-evaluation is the commenting on the performances of others in the group. This form of feedback is most often more accurate and truthful than the self- reflection, but it is also more complicated to give and receive with regard to interpersonal relationships (2,3). While the two first types of evaluation focus on an individual’s performance, group evaluations are used to assess the success of the group, as a whole, regarding learning but also group dynamics.

The effectiveness of evaluations can differ depending on multiple aspects. If there is a power imbalance between the person giving feedback and the person receiving (tutor to student or student to tutor) the feedback is regarded as asymmetric. For example, if the giver of the feedback has a higher status as the receiver the empathy of the giver can be diminished, which will ultimately lessen the quality of the feedback. In contrast to that we speak of symmetric feedback when the people who evaluate each other are on the same academic level (peers). It is a strength of the PBL setting, that peers are able to provide the more productive type of feedback, the symmetric feedback (1).

Is feedback always beneficial in group-learning-processes?

A study from 2013 wanted to address 3 research questions evaluating the effectiveness of midterm peer feedback in a PBL setting. The study focused on investigating if the quality of individual contributions increased after the midterm feedback (I), the effectiveness of feedback depends on whether the students are new to PBL or acquainted with the concept (II) and which points, do students think, can be improved (III). To answer these questions 87 first- and second-year students from Maastricht University performed a pre-test in the beginning of the term that would rate the quality of their PBL contributions, followed by an intervention in form of a midterm peer feedback and followed up by the same performance rating in the end of the term. This quantitative assessment of performance was complemented with a questionnaire that allowed for qualitative assessment of each individuals perception of peer feedback (4). Evaluating the data of the individual performance tests it was concluded that the feedback did not improve the performance of students that were already doing well in the pre-test. However, students with a poor rating in the pre-test profited from peer feedback and improved their contributions to the PBL group, which ultimately increases the quality of the PBL for the whole group. Unsurprisingly, students that were new to the PBL setting improved more than students of the second year as these are already comfortable in the setting of a PBL and so less susceptible for feedback or less willing to work on further improvements (4). One limitation of the study is that the peer feedback was given in written form. A pivotal part of receiving feedback is to completely understand what the other person means. The possibility of face- to-face discussion is crucial for feedback to be understood, accepted and heeded (3).

Another study brings forth the aspect of feedback tools not just being able to improve a groups cognitive performance but also the social interactions and satisfaction with the collaborative learning process (5). In this study the feedback tools “Rader” (peer feedback tool) and “Reflector” (self- evaluation) were used throughout the whole duration of the group project which could be superior to the one-time feedback approach the first study mentioned used. This could be a hint towards the importance of continuous evaluation throughout the whole process of a PBL semester.

Another possibility in which feedback can be elevating the quality of a PBL session is to evaluate not just the students but also the tutor’s performance. A study from 2017 found that peer coaching is an effective way to improve a tutor’s facilitation skillset. It was also observed that while self-evaluation after reviewing video footage can help to recognise bad behavioural patterns, peer feedback is required in most cases to actually improve the behaviour. Tutors claimed that a peer evaluation was benefiting them not just improving their approaches but also reassuring them in their work (6). A peer evaluation system for tutors can be a tool to improve the framework of a PBL to give the students the chance to profit most from a group learning approach.

Conclusion

Considering all points mentioned above one can conclude that using evaluations and feedback effectively is not an easy task. There are many different types of feedback and it is usually dependent on the situation but also on the personalities of the one giving and the one receiving the feedback, which type of evaluation is the most applicable (3). These circumstances could explain the results in studies which do not find any major improvements of group work performance after a feedback intervention. In a study from 2014 no enhancement of the quality of individual PBL contributions could be found after a one-time peer feedback intervention. However the authors proclaimed that just having 3 meetings after the intervention is probably too short of a time to establish new learning patterns and improvements in group interactions (7).

However, there is a lot of evidence to be found in the scientific literature that points to evaluation as a vital tool for improving group work performances (both intellectual and interpersonal). This is especially true when the right form of feedback is given with regard to the situation. It is also crucial to provide a professional environment, in which each group member feels comfortable giving and receiving feedback.

A personal reflection on PBL, by Natia Bendeliani

My story with PBL started when I decided to do a PhD, with minimal knowledge but with an eagerness to learn more about it. Skimming endless papers on PBL and finding the right loop for my research, I realized that I was falling in love without actually seeing PBL in a real classroom. Later on, I attended PBL class as a student and then participated in a workshop about PBL, but my understanding of how it really works and feels to be a PBL student or tutor was not completely clear.

Then I found the article ’what can PBL do for Psychology, but what can Psychology do for PBL?’ which has become the possibility of experiencing the whole essence of it. In September 2022, I was invited to Linköping University, where I had an opportunity to attend the PBL course, hosted by Sally Wiggins Young.

By the end of the course, I was able to analyze how learning happens in PBL class and what is the role of problems in this process.

‘But how does it work?’ This was my driving question in the course and as a learner, I’ve experienced it and now I will try to reflect on it. An intriguing puzzle or problem arises situational interest in the learner which leads to focused attention, and increased concentration. This phenomenon is described as a cognitively induced experience of knowledge deprivation (Schmidt, et al 2011). ‘Knowledge Deprivation’ is the combination of words I was looking for to describe my state after the first session of the PBL course because after brainstorming I identified many gaps and I wanted to revisit all articles I have ever read about PBL. At this moment, compared to my previous experiences, I was intrinsically interested and wanted to understand what is being studied and I had a situational necessity to know and understand whatever I was reading. Doing reading independently, without realizing the application of it did not happen to be memorable. “When information is presented out of context, or for some unspecified possible future use, students may not appreciate the importance of the information, which may affect their motivation to learn”(Hunt, Chalmers, 2012, p. 148). I would characterize this process as a very safe process, the learner does not need to face failure, but she/he sees gaps, which could be closed on stage 7 on the PBL wheel (Acquiring knowledge). While in a traditional classroom, when the teacher asks direct questions and tries to examine your prior knowledge can not always become the prerequisite of learning, but the moment of avoiding shame. In literature, this approach to learning is called deep learning. A review of the literature demonstrates that PBL does enhance a deep approach to learning because students are involved in the process of developing and explaining hypotheses, and searching for evidence to explain, conceptualize and apply (Dolmans et al, 2015). Several studies where micro analytical measurement approach is used have demonstrated that from the phase of problem presentation to the identification of learning goals the situational interest is increasing significantly, and when students start self-study and they take steps to the elaboration of what was learned the situational interest is decreasing, but not substantially (Schmidt, et al 2011).

‘But what is the nature of the problem?’ which is becoming the starting point in PBL class, that was the second question I wanted to address because as a tutor, we are supposed to design problems for the class. At the same time, it becomes a stairway to self-directed learning. In the article ‘All problems are not equal: Implications for Problem-Based Learning’ attention is made to the external factors that define the difficulty of the problem, which are external to the learner because factors such as level of domain knowledge, reasoning skills, experience in solving problems, etc. are the characteristics that can not be controlled by teacher/tutor. As I learned, the focus shall be made on the degree of complexity which is measured by the number, level of advancement, and degree of abstractness of concepts involved in solving problems. Complexity is also measured by the so-called solution path length, which refers to the steps needed for students to overcome. A second important parameter is the structuredness problems which encompass the following characteristics: transparency, stability, and predictability. Notably, the number of possible interpretations form ill-structured problems, and vaguely defined problems are considered highly ill-structured (Jonassen, Hung, 2008). Reflecting back to the vignette, we were given in the first session, seemingly it was ill- structured because it could have had many interpretations and we found it quite difficult to come up with one specific formulation of the learning outcome. Even though not all parties were happy with the given formulation of the problem, it still remained possible for everyone to do self-study and narrow down the topic they were interested it. Researchers identify two types of interpretations of problems. Vaguely defined problem, that can be interpreted in multiple ways and the second type is related to viable (feasible) solutions. By the end of the article general principles of designing problems are given, which we shall be considering while designing PBL problems. PBL problems should be open-ended, ill-structured but with a moderate degree of strucuturadness, on the other hand, complex, however, the degree of complexity should be motivating, challenging, adapted to students’ prior knowledge, cognitive development and readiness and last but not least, it should be authentic, which means that it’s adapted to the student’s future or potential workplace and are contextualized (Jonassen, Hung, 2008, p.16).

As a final saying, reflection can not be completed here, because in the PBL process not only designing problems but collaborative learning happens to have very significant importance because PBL as a whole concept of learning is based on a constructivist approach, but discussing cognitive benefits of group collaboration might need deeper analysis and it can elaborated in different paper.

The challenge of PBL in universities with high students/staff ratio by Shaimaa Nasr Amin

Problem-based learning (PBL) is a student-centered methodology of teaching that integrates knowledge deeply to promote learning (Maudsley and Scrivens, 2000). Unfortunately, it is not always applicable, especially in faculties with many students compared to staff members. That is the case in Cairo University, Egypt (my primary affiliation and home university) and the Hashemite University, Jordan (the current affiliation). In this case, traditional teaching seems to be the easiest solution and maybe the only model used for the financial and infrastructural makeup of the institution that hardens the implication of PBL activities. Teaching involved PBL activities with many students within large lecture halls is a difficult issue that puts a psychological burden on the educator. Moreover, it may evoke the feeling of conflict between what is available and what should be done to provide the students with the necessary skills to take the competitive positions for the postgraduate career or studies.

There are some approaches previously used by other institutions to overcome the challenge of PBL implementation for large groups. It is worth noting that; in universities that deliver teaching by traditional methods and plan to introduce PBL methodology, it is crucial to orient the students properly and ensure that the process that will be applied in PBL is transparent for them, and this orientation must be accomplished before the start of the course by a sufficient time. This pre-course orientation can be conducted through lectures or a written guide.

i-PBL scenario relative to the Course description:

The scenarios presented via the PBL should be linked and deepen the knowledge of the intended contents described in the course description. These scenarios should be appropriately planned according to the designed weeks for the course (usually 12-16 weeks). The tutor should arrange regular meetings and communicate through another platform like the course website or MS teams (Pastirik, 2006).

ii-Virtual or web-based PBL:

During the COVID pandemic, virtual PBL has been used and achieved positive outcomes (Haley and Brown, 2020). It will be a practical approach to consider web-based PBL, especially in institutions that use traditional learning as the students become familiar with the web-based environment and deal during the meetings for traditional lectures or virtual office hours. Different platforms can be used for the virtual PB like MS teams, zoom, and WebEx Haley and Brown (2020) studied virtual PBL using WebEx and provided the tutors and the students with the guidelines for the online-based PBL, for example, using the device, adjusting the setting for recording, video meetings, sharing files, technical issues. They also shared other rules to ensure the integrity of the process, like not using the browser for activities unrelated to the given problem’s activities. Professional training also has been arranged for the tutors through WebEx with backup facilitators for any unexpected technical problems during the live sessions. For the content delivered to the students, the cases were edited into day-to-day rather than whole case activity. Accordingly, the objectives have been modified to supply the students with swift guidance.

iii-Hybrid-PBL:

Another approach is to use both the PBL and traditional teaching as the principal teaching method; this approach is satisfactory for specific fields in which the nature of the subject makes this hybrid pattern of teaching meets the needs of the students like medical field (Lian and He, 2013). Lian and He (2013) studied the hybrid PBL; they divided the students into small groups and assigned 40% of the contact hours for PBL. The cases of PBL presented to the students one week before the session to be prepared and induce an independent pattern of learning. The session starts by showing the case in a large lecture hall in 2 or 3 slides. The students sit in this large lecture hall as groups as previously assigned, and after the slides presentation on the screen of the hall, the students start working within their groups. The time allowed for the first discussion was 5-10 minutes, and the tutor did not supervise these discussions as in this arrangement, there was one tutor in the whole large lecture hall. Then all groups participate in an open discussion briefly and concisely to allow all groups to be represented. The selection of the first group during the open discussion is achieved randomly, ensuring the attention and readiness of the other groups. Notes were taken during the open discussion on a whiteboard in the hall, and the tutor asked questions to keep the students on track. Additional data are presented, followed by the same sequence of closed groups discussion not guided by the tutor and open discussion by all groups guided by the tutor. The final case conclusion was reached through this random repeated format.

Lian and He (2013) evaluated their study on the hybrid PBL approach by exam and questionnaires: the students had written examinations at the end of the semester in the form of multiple-choice questions, short assays, and case studies. Besides, they shared two questionnaires to assess students’ preference for hybrid PBL versus lecture-based learning and students’ satisfaction.

In these few paragraphs, I tried to outline previous universities’ approaches with few staff compared to the students’ number, which interferes with applying straightforward PBL methodology. These approaches deserve to be tried in my university, especially with the reported outcome by the previously mentioned studies to achieve the best level of deep and student-guided learning.
