Principles of Adult Learning
Studies reveal that over a period of 3 days, the retention of learning is 10% of what we read, 20% of what we hear, 30% of what we see (demonstration), 50% of what we see and hear (discussion), 70% of what we say (practice), and 90% of what we say as we do (teach others, immediate use). It follows that an effective learning protocol is to watch one (demonstration), do one (practice), and teach one (use new learning). I hear and I forget. I see and I remember. I do and I understand.

PBL Goals and Objectives Overview of PBL Process Student Role in PBL (Active, Collaborative Learner) Evaluating Students in PBL Concept-Mapping Information Literacy
What is Problem-Based Learning? “ A learning method based on the principle of using problems as a starting point for the acquisition and integration of new knowledge. ” H. S. Barrows 1982
Principles of Adult Learning
PBL Goals § Knowledge – understand apply the science basic to medicine § Skills - scientific reasoning, critical thinking, problemsolving, information literacy, effective communication (the skills of self-directed, life-long learning) § Attitudes - value of teamwork and importance of feedback to personal and professional development
PBL Learning Objectives n Acquire, synthesize and apply basic science knowledge in a clinical context n Engage in analysis, critical thinking and problem-solving n Develop the ability to evaluate learning/gaps in knowledge and collaborate with peers n Effectively utilize information technology and identify the most appropriate resources for knowledge acquisition and hypothesis testing n Contextualize and communicate knowledge to others n Ask for, provide and incorporate feedback
PBL Learning Objectives Engage in analysis, critical thinking and problem-solving Contextualize and communicate knowledge to others Acquire, synthesize and apply basic science knowledge in a clinical context • Develop the ability to evaluate learning / gaps in knowledge • Effectively utilize information technology and identify the most appropriate resources • Ask for, provide and incorporate feedback collaborate with peers
Characteristics of the PBL Process Groups are small (7 -9 students) and collaborative Cases provide a relevant clinical context for inquiry, learning, and integration of basic sciences Cases are characterized by “progressive disclosure” of clinical information (history, physical findings, test results, clinical condition) Students are active participants in the learning process identifying gaps in knowledge, proposing/testing hypotheses and constructing/pursuing/reporting learning issues Tutors are custodians of the group process and guides to collaborative learning and discovery rather than content experts dispensing information.
n The PBL process Roles: Student: leader, reader, scribe, discussant Tutor: facilitator, guide, monitor Student tasks: Analyze the case Identify learning issues Pursue learning issues Present learning issues Critically analyze essential elements of the case and apply basic science learning to them

Good learning issues should…. Relevant to the case. Learning issues should clearly arise from prioritized hypotheses and must be both relevant and fundamental to addressing the concepts that arise in the case. “Owned” by the students. Identifying learning issues is an important part of developing life-long learning skills. Learning issues that are student generated are usually more meaningful and motivating. Specific, rather than too big or broad. However, sometimes a broad overview of a topic is indicated and relevant. When used excessively, LI presentations become redundant, over-bearing and boring. Clearly stated, using appropriate terminology, so that the tutor and students understand them. Framed so that they direct the student’s independent learning and guide their report during the next session. Most often, learning issues should consist of a specific, answerable question that is generated by the case. Organized so that they represent a logical sequence of learning about the case at hand.

Organizing Information – Concept Mapping In PBL, students analyze cases, develop hypotheses and pursue and report on student-defined learning issues. Keeping track of group learning and documenting group progress in understanding basic principles of the case is inherently difficult. Traditionally, students are taught to think and document in a very linear and hierarchical manner (i. e. , “lists” of symptoms or differential diagnoses are generated) rather than focusing on the relationships between concepts or case elements.
Organizing Information – Concept Mapping In contrast, concept maps allow the learner to “create an understanding of information by making connections, creating links as well as exploring and testing links” (Brussow, 2005) which promote the basic processes of problem solving, reflection and creative thinking. Concept maps have the potential for providing a “scaffold” for learning that promotes more effective and deeper understanding of knowledge domains (Novak, 2004). As such, concept mapping may offer a superb vehicle with which to record, track and promote group learning in PBL. As well, concept mapping may be a valid and reliable measure of what a learner understands (Rye & Rubba 2002).
Concept-Mapping
PBL and Concept Mapping “concept maps are graphical tools for organizing and representing knowledge” Concept maps emphasize relationships. In order to draw a line between to concepts, a student must be able to explain how they are related. The inability to draw a line (or link concepts) = a learning issue. A good way to define the context for a concept map is to construct a “focus question”, this is question that clearly specifies the problem or issue the concept map should have to resolve. Most often, this will be “How do we explain Anthony’s signs and symptoms? . . . How are they related? . . What is the underlying pathophysiologic process that explains what is happening to him? ” Concept maps are merely a means to an end…. not the end itself.
PBL and Concept Mapping • Keeping track of group understanding / progress • Generating learning issues • Presenting learning issues • Summarizing group knowledge at end of case • Assessing learning outcomes
