OVERVIEW:
Virtual reality: perspective is everything (VRML)
AUTHOR(S): Charles Parker
VITAL
INFORMATION
Subjects:
Introduction
to computers
Unit
and Topic:
Basic
VRML programming to teach students the integration of virtual reality images
with the concept of perspective in an Art class.
Grade/Level:
6th
Time
Allotment:
Five
days ( 48 minute periods)
Pre-Requisite
Skills:
Students must
have
- Basic typing skills and familiarity with
Micro- Soft Office
Objective(s):
The students
will be able to:
- Create a rectangular room in Text pad
and then insert a tabletop into this virtual room. Upon successful completion of the
programming segment of the lesson, the student will be able to view these
objects in 3d and using the translations and rotations function of VRML
will be able to manipulate these items to get an understanding of how the
point of perspective (the Vanishing Point) changes depending on the orientation.
The student will make connections between 3D graphics, art class and
career applications.
Summary:
The
student will gain insight into career applications, learn basic VRML
programming and make connections to art class.
The student will use a handout and information from teacher modeling to
create these objects in Textpad.
PREPARATION
Instructional
Materials: Handout for VRML steps, list
of VRML shortcuts and color charts.
(These resources are attached at the bottom of this document.
Resources:
- Computers with VRML, Textpad and CITERA
tools loaded, smart board for teacher modeling
IMPLEMENTATION
Introduction/Motivation:
·
The
class will engage in discussion about 3D graphics, careers in this field and
how it relates to other subjects. The students will engage in hands-on computer
programming and will engage in peer teaching as they teach the student form the
art class how to create the virtual room.
Learning
Context :
This
lesson fits into my career exploration and introduction to computers unit.
Procedure:
The
teacher will summarize the discussions of the career and graphics dialogue and
then model for the students how to create the required shapes in a Textpad
using VRML.
Differentiated
Instruction:
The
students will be paired for this assignment and lower level students will be
paired with higher-level students as needed.
Sample
Student Products:
Collaboration:
Students will begin work as
individuals and will be paired by ability as needed. After the initial lesson each
of them will pair with an art class student and through student (peer) teaching
they will work as teams to help the art student complete a virtual room. The
art student will help the computer student understand the concept of
perspective.
N.B.: In one of three succeeding 9-week rotations (marking periods)
each computer student will be similarly teamed again, but this time in the
position of art student*, further reinforcing what they
learned this quarter from their art student-partner.(*This could
be done with many other classroom teachers such as science teachers and using
VRML for the solar system.)

Comments & Reflections:
This
is my first foray into teaching this subject matter or co teaching with an art
instructor. Any feedback will be greatly appreciated and this lesson will be
updated as needed. Make sure that you explain the error messages and how to
read which line of code is incorrect and the procedure to fix them.
This
lesson works very well with the connections to perspective like the CSO’s
in an art class. The lesson could be
easily adapted to math concepts, social studies, science and many other areas
in curriculum. The age group that I tried this lesson with ranged from 6th
grade to 10th and they were equally engaged. This particular lesson can be adapted to many
grade levels and abilities.

knowledge to change tabletop to jpeg image etc.
The student
has two boxes inserted into the room.
The student
has correctly saved the project to a flash drive, labeled it, and can retrieve
it in text pad.
ADDENDUM
VRML project code: If the students copy the following code they
will end up with the virtual room outlines in the lesson plan. If the code is
opened in Textpad, it will show up in color.
