2. Some activities from the course to look at
3. Was the approach successful? – some results

Why Critical Thinking?
“If engineers are to be more than technical functionaries in the next millennium, there is a need to provide young engineers with …skills in critical analysis and ethical judgement and an ability to assess the long term consequences of their work.”
BEDER, S. 1999. Beyond Technicalities: Expanding Engineering Thinking, Journal of Professional Issues in Engineering Education and Practice, January , pp.12 – 18, pg12.

What is Critical Thinking?
1. Assumptions: a. uncertainty exists, b. no one right answer
2. The critical thinking process: (adapted from Cottrell, 2005)
- Collect knowledge from many sources
- Identify sources’ positions / methods / approaches
- Question the evidence and identify limitations
- Draw own conclusions
Skills@Library
Stages of the development of Critical Thinking
St. Characteristics Learning activity
1 Knowledge is certain, concrete Rote learning
2 Knowledge is certain, not everyone has access to it
Explore pros and cons of a problem
3 Knowledge is certain in some areas and temporarily uncertain in others
Identify own perspectives
4 Knowledge is uncertain due to limitations of knower
Explore other’s perspectives in groups
5 No knowledge is certain – all interpreted by individual knower
Class discussions challenge perspectives
6 Knowledge is uncertain and depends on context and evidence
Explore unanswered question in writing
7 Knowledge is outcome of process of inquiry Analyse new problems – inquiry process
Adapted from King and Kitchener (1994) and Kronholm (1996) in Siller (2001)

Critical thinking: Ice-breaker
Discuss:
Women are better drivers than men.
Student response: ‘but what is the right answer?’

1. When I am searching for information online, I always question the reliability of the sources I find.
4 = strongly agree, 3 = agree, 2 = sort of agree, 1 = disagree, 0 = strongly disagree
Skills@Library
Seven Pillars of Information literacy
1. Recognise a need for information
2. Distinguish ways to address the information gap
3. Construct strategies for locating information
4. Locate and access information
5. Compare and evaluate information obtained from different sources
6. Organise, apply and communicate information to others appropriately
7. Synthesise and build upon existing information, contributing to the creation of new knowledge
Skills@Library
Critical thinking in literature searching
Construct research question (s) Mindmap exercise
Select appropriate sources Primary and secondary sources exercise Academic and popular sources
What is a journal?Consider language Search tools and techniques (workshop)
Matching need to appropriate tools Tracking down the full text article
Evaluating and referencing and plagiarism exercises
Skills@Library
Writing a Literature Review: What is one anyway?
The purpose of a literature review is to summarize, synthesize and critique the sources relating to your topic.
OR
To provide an overview
To evaluate sources
To categorise sources
To compare sources
To make links to your project
NB: Critical thinking + joined-up thinking! (links)
NB: Paraphrasing!
Skills@Library
Writing a Discussion Section
Hardest section to write!
- Principal findings
- Strengths and weaknesses of study
- Comparison to other studies (references)
- The meaning of this study for the field- Unanswered questions: further study
NB: Critical thinking and joined up thinking

general

Results: Critical Thinking Self-Assessment
- Pre-test in intro. lecture; post-test in final lecture.
- Paired sample T-test using SPSS 14
- Average score pre-test = 52.8 / 80
- Average score post-test = 61.3 / 80
- Scores increased by average of 8.5 points
- It is unlikely that this increase is due to chance
- (1:1000 probability that this is due to chance)

The Learning Log
- The most useful thing I have learned today
- What I have learned today that I can apply to:
- my project
- my ethics essay
- my professional development
- my critical thinking skills
- Any other comments
Skills@Library
Results: Learning Log Feedback
‘There is no link between this lecture and my project’
‘I cannot see how writing a literature review will be helpful in my professional life.’
‘[Critical Thinking is] not throwing away other’s ideas I may not agree with.’
‘My personal experience in the glass industry could affect the approach I take to my project. I should evaluate other methods to see if they are relevant.’
Skills@Library
Results: other effects
- Attendance from 50% last year 80-90% this year
- Greater engagement: > number of questions / comments
- First Mech. Eng. drop in students at Skills@Library
Skills@Library
Personal Reflection
- Lower level of writing and CT than expected
- Reluctance to read
- Reluctance to write
- Unfamiliarity with journal articles
- Learning log – 2 way communication

Conclusion
1. More awareness raising input on Critical Thinking is needed
2. Developing CT skills is a slow burn (long time period needed)
3. Developing CT skills is best embedded in a subject
