PBL as a strategy for change: development and diversity of practice

• Problems as focus and stimulus for learning• Self directed learning• Student-centred and tutors as facilitators/guides• Team work

• Problem orientation• Interdisciplinarity• Exemplary learning• Participant directed• Group work

5

What is/are PBL(s)?

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

6

What is/are PBL(s)?

PBL reflects the way people learn in real life; they simply get on with solving the problems life puts before them with whatever resources are to hand.

(Biggs 2003)

7

What is/are PBL(s)?

Problem-based learning helps students to see that learning and life take place in contexts, contexts that affect the kinds of solutions that are available and possible. (Savin-Baden 2003)

8

What is PBL?

Problem based learning is a pedagogical strategy for posing significant, contextualised, real world situations, and providing resources, guidance and instruction to learners as they develop content knowledge and problem-solving skills (Mayo et. Al., 1993)

9

What is PBL?

–PBL is Student-Centred Learning–Where motivating and activating

students is the prime concern–The point of departure for the learning

process is an ill-structured real life problem

Teaching = Learning ?

13

Teaching = learning?Yes, it’s

actually true – you can get a

degree by repeating

everything the teacher says.

”We pretend that there is co-incidence between what is being taught and what is being learned” (Knud Illeriis, 1998)

14

Teaching = Learning?

(Karl Smith, UMN)

“Teaching does not mean transferring knowledge but creating opportunities for …producing and constructing it.” (Paulo Freire)

15

Learning – is it only about how brain works?

16

Constructivist view on Learning• Learning is not only a process of

transferring knowledge to the students, who should not be passive receivers

• Too much learning directed towards curriculum that the student must learn (or rather memorize)

• Overweighed focus on assessment measurement of the knowledge students have memorized – but not ability to produce new knowledge or to use their knowledge in real settings

Philosophy and theories related to PBL

17

Constructivism on learning• Knowledge and learning created

by students – not given• Learning and knowledge

construction is facilitated by collaboration – dialogue, critical reviews, coordinating efforts.

• Knowledge and learning should be about construction, and not re-construction of knowledge

• Learning is about producing new knowledge, solutions, theories and methods.

A conceptualisation of PBLPBL can be conceptualised as three central dimensions or

processes that are stretched between teacher and participant control:– Problem – who defines and re-formulate?– Work Process – who chooses theory, methods and

ways of working?– Solution – who owns the solution?

PBL – Regional development• PBL AAU as a good example of linking students with the local

economy (OECD 2007, Puukka and Marmolejo 2008)– Students benefit from

• Gaining transferable skills and authentic work experiences– University benefits from

• gaining feedback and access to instructive cases and ideas for research and teaching

• Improving graduate retention • Higher rate on-time finishing ( AAU 87% v.s 38% others in

DK) • Lower drop-out rate (AAU lowest in DK)• Improved interdisciplinary collaboration among teaching

staff – Enterprises benefit from

• A clearer picture of what the university stands for and how the students might fit in as prospective employees

Taxonomy PBL practice (Barrows 1986)

• Lecture-based cases: cases used to demonstrate the relevance of information provided by lectures

• Case-based lectures: cases are used to highlight material that will be covered in the subsequent lecture

• Case method: cases are studied in preparation for class discussion

• Modified case-based method: cases provide opportunities for deciding between a limited number of options

• Problem-based learning: cases are used in a problem simulation format that encourages free inquiry

• Closed loop, or problem-based learning: a reflective phase complements the problem-based format

Types of projects – nature of problems

– The task project– The discipline project– The problem project

Problem and Project in AAU PBL

THE TASK PROJECT

Problem Discipline

• Considerable planning and control by the supervisors • The problem and the subject as well as the methods are chosen

beforehand• The educational objectives are easily controlled• More control

An Example:

In firm X they have a machine emitting too much noise.

The task given is to measure the noise level, to calculate the necessary attenuation and find a silencer.

THE DISCIPLINE PROJECT

DisciplineProblem

An example:

a description of the scientific objectives as using a digital signal processor and creating a filter.

The student will then have to start by finding a problem where a filter is needed in the solution and it would be a good idea to use a digital signal processor.

• disciplines and methods are chosen in advance • students identify and define a problem within the described disciplines • educational objectives are mostly formulated for each discipline• supervisor - a bit uncertain, however, the scientific field is described well

THE PROBLEM PROJECT

Problem Discipline

• problems as the starting point• The problem will determine the choice of disciplines, theories and

methods• educational objectives emphasises ability to analyse and methodological

skills • The problem has to be chosen within a broader social and technical frame• a self-directed learning process• supervisor – challenging (can be part of the big research projects)

An example:In firm X there is too much noise emitted in the production hall.Analyze the problem in order to find the noise sources and find solutions.

‘It is so exciting to work on this, we solve problems and we see things happen…’ - Students from EE

‘It is boring to only focus on technical things… I don’t want to become nerds by studying engineering. I want to work with technology in a creative way and to do something for people…’ - Students from A&D

International Master Program of Environmental Management

Semester 1 ThemeCompany perspective – Environmental management industries and

cleaner production and products

Project focus In-depth analysis of a company’s environmental strategies and

performance and suggests improvements in relation to production processes, the product life cycle, or management policies. At the end of the semester, a project report is submitted, presenting relevant theories and an analysis of the case study.

Group 3: Environmental Impacts of Passive Houses (group 3 report)

Contextand aims

To determine how significant the choice of materials is when designing energy-efficient houses in relation to their lifecycle environmental impacts.

Researchquestion

Controlling for energy efficiency and design, what are the estimated costs and environmental impacts related to two energy-efficient houses, conceived in accordance with either a sustainable development or an energy efficiency criteria?

Theories Life cycle thinking, sustainable development and construction, passive house, passive and active systems, big bale building, LS/EPS Passive house

Researchmethods

Case study, interviews Costs analysis, life cycle assessment

Results The construction costs were the most persuasive element of the partialresults. The BBB is significantly less expensive to construct. The usestage showed an important financial dominance over the two otherstages. The global warming category revealed itself to be the mostimportant feature to consider among the environmental categoriesselected in this study, and at a lesser degree nutrient enrichment. Thechoice in the materials is of great importance of the other stagesespecially in relation to the embodied energy due to transport which

formed an important feature in LS/EPS impact profile.
