Spatial Visualization

Standard Test:

Fig 3

a)Mental Cutting Test

Mental Cutting Test - Subjects have to mentally cut 3D geometrical figures which are

hollow. The figures are to be cut using a plane or another geometrical figure and

resulting cross section is to be determined..

Examples of Mental Cutting

Test

Proposed by

(CEEB,1939)

Study

Spatial Visualization

Standard Test:

Fig 3

a)Mental Rotation Test

Mental Rotation Test - the subject is asked to compare among options of rotated 3D

objects to tell which option matches the object in the question.

Example of Mental Rotation Test

Proposed by

(Vandenberg

& Kuse, 1978)

Technology

Acceptance

Model:

Fig 3

Models how users come to accept and use a technology. When users are presented

with a new technology, a number of factors influence their decision about how and

when they will use it, notably:

•Perceived usefulness (PU) - This was defined by Fred Davis as "the degree to which

a person believes that using a particular system would enhance his or her job

performance".

•Perceived ease-of-use (PEOU) - Davis defined this as "the degree to which a person

believes that using a particular system would be free from effort"

Proposed by

(Davis, 1989)

Technology

Acceptance

Model:

Fig 3

Perceived usefulness and perceived ease of use have been extensively

investigated in a number of studies, which proved that they are important factors

positively influencing computer acceptance .

Perceived enjoyment -Studies proved that has a significant positive influence on

attitude toward using, thus, it should be included in the TAM model

Design Project 4

Empirical Study

Research Aim:

Fig 3

1)To measure the effect of the VR learning tool on the performance of the

students for the topics of Projection and section of solids.

2)To find out the attitude of students towards using this tool for their learning

based on TAM.

Empirical Study

Controlled

Experiment Design:

Fig 3

Hypothesis:

Immersive VR significantly improves the performance of students in learning

projection and section of solids.

Treatment Group: Student using Immersive VR for Learning.

Control Groups: Student taught only through conventional methods.

Independent Variable: Use of Immersive VR

Dependent Variables: Score on given Quiz, Time

Design Project 4

Empirical Study

Experiment

Procedure:

Fig 3

Pre Test Questionnaire: Collect biographical information from students prior to the

experiment. Apart from background details, this includes questions about their grades,

gaming habits and past experience with gestural + virtual interfaces A small spatial

visualization test would also be given to them.

Making the clusters of students having the similar academic performance in

their Engineering Drawing Exam.

Random Assignment: Assigning 20 students each randomly to both treatment

group and the control group.

Design Project 4

Empirical Study

Experiment

Procedure:

Fig 3

Instruction: The treatment group would be taught the topic using the VR tool,

the control group would be taught with the instructional content used in the

course i.e. animated videos and lectures.

Performance Evaluation :After the instruction, they would be asked to take a

quiz which would include multiple choice questions based on mental cutting test,

mental rotation test and 5 informal sketching questions. Time for doing the test

would also be evaluated

Measuring Acceptance: They treatment group would also be asked to fill up

the post-questionnaire to measure their attitude towards using Immersive VR as

a learning tool

Think Out aloud and qualitative question being asked to understand the actions

of students more deeply.

Perceived usefulness (PU)

• The use of such a system improves learning in the classroom.

• Using the system during lessons would facilitate understanding of certain concepts.

• I believe that the system is helpful when learning.

Perceived ease of use (PEU)

• I think the system is easy to use.

• Learning to use the system is not a problem.

• Operation with the system is clear and understandable.

Perceived enjoyment (PE)

• I think the system allows learning by playing.

• I enjoyed using the system.

• Learning with such a system is entertainment.

(5 point Likert scale items with results from strongly disagree to strongly agree)

Attitude toward using (ATU)

• The use of such a system makes learning more interesting.

• Learning through the system was boring (reversed item).

• I believe that using such a system in the classroom is a good idea.

Intention to use (ITU)

• I would like to use the system in the future if I had the opportunity.

• Using such a system would allow me to learn projection and section of solids

on my own.

• I would like to use the system to learn engineering drawing and other

subjects.

Other questions would be regarding content and motivation to learn
