IntroductionOnline tutorials for 3rd year aerospace courses

Topics that will be covered

◦ Introduction to composites (with colleague)

◦ A,B and D matrices in laminates

◦ Failure theories in composites

Why create online tutorials?Easier to manage and easily accessible

More appealing to students

 Aim of the studyThe main aim of the study is to investigate if there is a

relationship between the performance of students in an

online tutorial and their perception of the tutorial.

Performance

◦ Data obtained from the results of the students

Perception

◦ Data obtained from feedback provided by students

Quantifying perceptionStudents respond to descriptive statements of the tutorial

Negative response weighted lower and positive response

weighted higher

◦ Strongly Disagree (-2)

◦ Disagree (-1)

◦ Neutral (0)

◦ Agree (1)

◦ Strongly Agree (2)

What is feedback?Feedback is information that can influence the path of asystem

◦ Path here is student’s performance in the tutorial 

Feedback can be of grouped intoNon-adaptive feedback

◦ Simple cognitive feedback (right or wrong)

Adaptive feedback◦ Diagnostic feedback (where you went wrong)

◦ Prescriptive feedback (how to get the right answer)

What is feedback?

Previous researchRaad (2012) and Tuli (2012) considered the effects of different

feedback on performance

Study performed in Semester 1 2012

Utilised tutorials that were created for AERO3410

◦ Closed section shear flow tutorial

◦ Open section shear flow tutorial

Previous researchEstablished that adaptive feedback made students more efficient

◦ 30% less time taken to complete tutorials

Perception of tutorials was more positive for adaptive feedback

MethodologyChoose topics

Concepts that are

hard to visualize

Storyboarding

Helps visualize thetutorial

Unnecessary

content is removed

Helps design theflow of the tutorial

Creation

MethodologyTutorials created using Smart Sparrow platform

◦ Completely online

◦ Graphical interface

Advantages of Smart Sparrow

◦ Creation of trap-states

◦ In-depth tracking of student performance including

◦ Time spent

◦ Number of wrong attempts

◦ “Pathway” followed by students

MethodologyCross-over study

◦ One group receives adaptive feedback

◦ Other group receives non-adaptive feedback

Group 1

Non-Adaptive

Feedback

Group 2

Adaptive

MethodologyIn the next tutorial, the feedback is swapped, so as to :

◦ Prevent any students being disadvantaged

◦ Acquire more refined data

The data that is obtained from these tutorials is thenanalysed

Group 1

Adaptive

Group 2

Non-Adaptive

IssuesEthics of testing on humans

◦ Application rejected in first semester (3 month delay)

◦ Inability to use any data from first semester

Non-serious response from students

Future work and conclusionFramework for study is designed and ready to be tested

Study the role of perception inducing factors such as

◦ Time taken

◦ Visual style

Data obtained from previous studies supports thehypothesis, however more definite testing has to beperformed.
