Problem-Based Learning Model

Problem-Based Learning (PBL) is an educational approach that focuses on using real-world problems to drive student learning. Instead of relying on the traditional method of presenting facts and concepts directly to students, PBL engages students in solving complex, authentic problems. It is a student-centered teaching method that encourages active learning, critical thinking, problem-solving skills, and effective communication.

In PBL, students are presented with a challenging problem that mirrors a real-life situation. These problems are often interdisciplinary, requiring students to draw knowledge and skills from various subject areas. The problems are open-ended, meaning there are multiple possible solutions or approaches. Students work collaboratively in small groups to analyze the problem, identify relevant concepts and principles, and develop potential solutions.

The role of the instructor in PBL is that of a facilitator or guide rather than a lecturer. The instructor helps students identify key learning objectives, provides necessary resources and guidance, and encourages critical thinking and reflection throughout the problem-solving process. The emphasis is on students actively constructing their knowledge through inquiry and discovery rather than passively receiving information.

PBL offers several benefits to students. Firstly, it promotes a deep understanding of concepts and principles by connecting them to real-world applications. Instead of memorizing facts, students engage in meaningful problem-solving that requires them to apply their knowledge in context. This approach enhances long-term retention and transferability of knowledge.

Secondly, PBL develops critical thinking and problem-solving skills. By grappling with complex problems, students learn to analyze information, evaluate different perspectives, and generate creative solutions. They also learn to think critically about the quality and reliability of research materials and evidence, fostering information literacy.

PBL encourages effective communication and collaboration. Students must work together in groups, exchanging ideas, negotiating solutions, and articulating their reasoning. This cultivates teamwork, interpersonal skills, and the ability to communicate complex ideas effectively.

PBL can be implemented in various educational settings and contexts. It can be used as the primary instructional method throughout a semester, integrating problem-solving activities into the entire curriculum. Alternatively, it can be incorporated into specific classes, such as laboratory experiments or design projects, to provide hands-on, practical learning experiences. PBL can also be utilized for initiating discussions or creating assessment tasks, enabling students to demonstrate their understanding and problem-solving abilities.

When adapting any subject area to Problem-Based Learning (PBL), certain characteristics of good PBL problems can be considered. These characteristics apply across disciplines and are outlined as follows:

  • Motivating students: The problem should spark students’ curiosity and drive them to seek a deeper understanding of the underlying concepts. By presenting a challenging and relevant problem, students are motivated to explore and learn.
  • Reasoned decision-making: The problem should require students to make informed decisions based on critical thinking and logical reasoning. Students must analyze the problem, consider various options, and provide justifications for their chosen solutions.
  • Connecting to previous knowledge: The problem should be designed in a way that connects the content objectives to students’ prior knowledge or previous courses. This helps students see the relevance and applicability of their existing knowledge in solving real-world problems.
  • Promoting collaboration: If the problem is intended for group projects, it should possess a level of complexity that necessitates collaborative work among students. The problem should be challenging enough that individual efforts alone may not lead to a satisfactory solution, thereby encouraging teamwork and cooperation.
  • Engaging multistage projects: In the case of multistage projects, the initial steps of the problem should be open-ended and captivating. By presenting the problem in an intriguing manner, students are drawn into the learning process from the beginning, fostering their engagement and investment in finding a solution.

Guidelines For Creating Problem-Based Learning (PBL) Problems

This section provides guidelines for creating problem-based learning (PBL) problems, particularly in the context of a classroom setting. Problem-based learning is an instructional approach that focuses on solving real-world problems to promote critical thinking, problem-solving skills, and a deep understanding of concepts.

1. Choose a central idea, concept, or principle:

Select a fundamental topic that is typically taught in the course. This could be a key concept, principle, or idea that students need to understand.

2. Find a typical end-of-chapter problem or assignment

Identify a problem or assignment that is commonly used to help students learn the selected concept. This problem will serve as a starting point for the development of a more engaging and real-world-oriented problem.

3. Develop a real-world context

Introduce a real-world context or scenario that relates to the chosen concept. This could involve adding a storytelling aspect to the problem or researching an actual case that can be adapted. The aim is to provide motivation for students to solve the problem and encourage them to explore applications of the concept in practical situations.

4. Introduce the problem in stages

Break down the problem into stages or pages to guide students’ learning process. Each stage should raise open-ended questions and present learning issues that prompt students to research and explore the targeted concepts. This incremental approach helps students identify what they need to learn and guides their research.

5. Determine the structure and duration

Consider how the problem will be structured and how long it will take to complete. Decide on the number of class periods or sessions required. Additionally, determine whether students will receive information gradually as they progress through the problem.

6. Identify necessary resources

Determine the resources that students will need to solve the problem effectively. This includes both physical resources, such as books or articles, as well as digital resources like websites or databases. Encourage students to utilize various resources, including libraries and the Internet.

7. Define the end product

Specify the expected outcome or end product that students should produce upon completing the problem. This could be a written report, a presentation, or any other form of demonstration that showcases their understanding and application of the targeted concepts.

8. Create a teacher’s guide

Develop a detailed instructional plan for teachers on how to implement the problem in the course. This guide may include a combination of mini-lectures, whole-class discussions, and small group work with regular reporting. It helps teachers navigate the different stages of the problem and suggests strategies for facilitating student learning.

9. Provide key resources for students

While students are encouraged to independently identify and use learning resources, it can be helpful for instructors to recommend a few reliable sources to get them started. Encourage students to go beyond the internet and explore resources available in libraries or other relevant sources.

By following these guidelines, educators can design engaging problem-based learning experiences that promote active learning, critical thinking, and the application of knowledge in real-world contexts.

The method for distributing a problem-based learning (PBL) problem involves three teaching techniques: case studies, role-plays, and simulations.

  • Case studies: In this technique, students are given written descriptions of real-life situations or problems. These case studies provide detailed information about a particular problem, allowing students to analyze and understand the context, identify key issues, and propose solutions.
  • Role-plays: This technique requires students to act out or improvise scenes based on given character descriptions. Through role-plays, students can explore different perspectives, understand the motivations and behaviors of various stakeholders, and develop problem-solving skills by considering different viewpoints.
  • Simulations: Nowadays, simulations often involve computer-based programs. In this technique, students engage in interactive virtual environments that replicate real-world scenarios. They can manipulate variables, make decisions, and observe the consequences of their actions. Simulations provide a hands-on experience that allows students to apply theoretical knowledge, develop critical thinking skills, and understand the complexities of real-world problems.


These advantages contribute to a more engaging and effective learning experience, preparing students for future challenges and success.

  1. Enhance Student-Centred Learning

One advantage of problem-based learning (PBL) is that it enhances student-centered learning by actively involving students in the educational process. In PBL, students are not passive recipients of information but are actively engaged in problem-solving activities. This active involvement fosters a sense of ownership and empowerment, as students take responsibility for their own learning. By participating in the process of identifying and solving problems, students become more invested and interested in the subject matter. Their active engagement leads to improved motivation and a higher level of satisfaction with the learning experience.

Additionally, PBL promotes the retention and development of lifelong learning skills. By confronting students with real-world problems, PBL encourages the application of knowledge in practical contexts. This application-based approach not only helps students understand the relevance of what they are learning but also enhances their ability to retain and transfer knowledge to different situations. Moreover, PBL stimulates the development of deep learning, where students engage in critical thinking and problem-solving strategies. They learn to analyze complex issues, draw connections, and think critically, which are essential skills for lifelong learning. PBL also encourages self-directed learning, as students take charge of their own learning process and develop the ability to seek out information, resources, and solutions independently.

  1. Upholds Lifelong Learning

Problem-Based Learning (PBL) has the advantage of upholding lifelong learning. PBL fosters a student-centered approach where learners actively participate in problem-solving scenarios. This method encourages students to identify their learning goals, seek out relevant resources, and take responsibility for acquiring the knowledge needed to address the problem. By engaging in self-directed learning, students develop skills such as goal-setting, resourcefulness, and accountability, which are essential for lifelong learning. Additionally, PBL promotes long-term knowledge retention by promoting deeper understanding and application of concepts. By connecting new information to real-world problems, students develop a comprehensive understanding of the subject matter, enhancing their ability to transfer knowledge to future situations.

  1. Enriches the teacher-student relationship

Problem-Based Learning (PBL) has the advantage of enriching the teacher-student relationship. In PBL, students are self-motivated, engaged in teamwork, and take charge of their own learning. As a result, teachers who have experience in both traditional and project-based learning formats often prefer PBL because they find it more nurturing and beneficial to the cognitive growth of students. The shift in the teacher’s role from a sole provider of information to a facilitator and mentor allows for a more collaborative and interactive relationship. Teachers have the opportunity to guide and support students as they explore real-world problems, providing feedback, individualized instruction, and fostering a sense of trust and mutual respect.

Moreover, PBL enables a more meaningful and personalized curriculum. By incorporating real-world problems, students can see the relevance and practical application of what they are learning. This sense of purpose and intrinsic motivation enhances the teacher-student relationship as students become actively engaged in the learning process. Teachers can tailor instruction to meet individual student needs, offering guidance and support tailored to each student’s progress and challenges. The personalized nature of PBL fosters a stronger connection between teachers and students as they collaborate, problem-solve, and develop a deeper understanding of the subject matter together.


  1. It’s Time-consuming

Problem-based learning (PBL) has the disadvantage of being time-consuming for both students and instructors. While PBL offers benefits such as improved problem-solving abilities and engagement, it requires instructors to invest more time in assessing student learning and preparing course materials compared to traditional lecture-based learning (LBL). In PBL, students actively participate in solving real-life problems, which involves extensive research, data analysis, and collaboration. As a result, instructors need to dedicate significant time to assessing each student’s progress, evaluating their problem-solving skills, critical thinking abilities, and application of knowledge to practical situations. This individualized assessment process takes more time than the conventional methods of evaluating an entire class simultaneously.

Additionally, PBL involves student presentations where they share their research findings and insights with the class. This presentation component adds to the time requirements, as each student needs to be given an opportunity to present their work. Unlike LBL, where the instructor delivers information to the entire class at once, PBL necessitates allocating time for individual presentations. Moreover, the brainstorming sessions in PBL, which aim to generate ideas and explore different perspectives, can be perceived as disorganized and time-consuming. Instructors must invest additional time in facilitating and guiding these brainstorming sessions to ensure productive outcomes. These factors contribute to the overall time-consuming nature of PBL, requiring instructors to spend more time on assessment, student presentations, and managing the collaborative problem-solving process.

  1. Traditional Assumptions Of The Students

One disadvantage of problem-based learning (PBL) lies in the traditional assumptions of students. In many traditional educational settings, students are accustomed to viewing their teachers as the primary source of knowledge. They are used to being passive recipients of information, expecting their teachers to provide them with all the necessary knowledge and answers. This mindset can pose a challenge in the initial years of PBL.

When students transition to problem-based learning, they are expected to take on a more active role in their learning process. They are required to independently explore and seek out information, critically analyze problems, and develop their own solutions. However, due to their previous educational experiences, students may struggle to adapt to this new approach. They may initially lack the ability to engage in open-ended inquiry and may find it difficult to generate their own questions and ideas without explicit guidance.

  1. Pupil’s Evaluation

One disadvantage of problem-based learning (PBL) is the challenge it poses for evaluating students’ achievements. In traditional lecture-based learning, assessment methods often revolve around written examinations with objective questions. However, in PBL, instructors need to adapt and employ new assessment methods to effectively evaluate the pupils’ progress.

These modified assessment methods may include written examinations with modified essay questions that assess the students’ critical thinking and problem-solving skills. Additionally, practical examinations can be used to evaluate how well students can apply their knowledge in real-world scenarios. Peer assessments, where students evaluate each other’s performance, and self-assessments, where students reflect on their own progress, are also incorporated to provide a comprehensive evaluation of the students’ learning outcomes.

The need for these diverse assessment methods in PBL can be seen as a disadvantage because it requires instructors to develop and implement new evaluation techniques. This process may demand additional time and effort from the instructors, as they have to familiarize themselves with these alternative assessment approaches and ensure they are fair and effective in evaluating the students’ achievements.
