OVERVIEW: Apply mathematical concepts while learning basic VRML programming
AUTHOR(S): Melissa Hissem
VITAL INFORMATION
Subjects:	Technology
Unit and Topic:	Unit: Gamers’ Paradise: Video Gaming Across the Curriculum Topic: Basic VRML programming
Grade/Level:	9-12
Time Allotment:	1.5 hours
Pre-Requisite Skills:	Basic geometry concepts (taught during the previous session)
Objective(s):	Students will be able to create three-dimensional cones, cylinders, and spheres using a computer programming language. Students will be able to manipulate computer-generated cones, cylinders, and spheres by altering programming code. Students will be able to identify the relationship between geometry concepts and computer programming.
Summary:	Students will create three shapes (cones, cylinders and spheres) using VRML. Students will first learn the basic programming skills necessary to create these shapes (including how to open TextPad and how to view their progress). They will then learn how to use geometry concepts to manipulate the size of the shapes (radius, height, etc.). Students will be asked to apply what they have learned to create and alter specific shapes. A discussion about IT careers, video game development, and computer programming will be incorporated into the lesson.
PREPARATION
Instructional Materials	Handout 1: VRML handout and corresponding PowerPoint Handout 2: Code for first shape Handout 3: Code for all three shapes Handout 4: Assignment
Resources:	Computers (1 per student) Computer/projector/screen (1 total) Copier Technology resources: Textpad VRML Tools PowerPoint (on teacher computer)
IMPLEMENTATION
Introduction/Motivation:	Refer back to the video game and tell students they will get a taste of what video game programmers do. Students will experience hands-on computer programming.
Learning Context :	This lesson gives students a chance to apply mathematical skills Computer skills are necessary both at school and in the workplace This relates back to the overall theme of video game development Students will transition from programming to writing/literacy/story development
Procedure:	Introduce students to programming and explain that programming is an integral part of video game development AND a way to apply mathematical skills, including those they just learned Introduce VRML and show example (PowerPoint) Explain objective: Students will not create video games; they WILL learn how to create basic geometric shapes and learn how to adjust the size and color of these shapes (PowerPoint) Using a handout and PowerPoint presentation, walk students through a basic program (sphere, cylinder, and cone at different locations on the screen). Give students the code for the first shape, then give them an opportunity to figure out how to create the other two shapes on their own (Handouts 2 and 3) Give students their assignment: Change the size and color of the three shapes they have created (Handout 4) Emphasize how important details are in programming; for example, one misspelled word will cause the program not to work Transition to English segment of the unit
Differentiated Instruction:	Information will be presented both verbally and visually. Students will have the opportunity to help each other.
Sample Student Products:
Collaboration:	Students will have the ability to collaborate with each other.
Author's Comments & Reflections:	Although boxes (cubes) were not incorporated into this lesson (time constraints), they could certainly be added. Some students will finish the activities very quickly. Try to engage these students while they are waiting for the others to finish (e.g., teach them how to use the color picker, review what they have already learned, etc.)

NT.K-12. Technology Productivity Tools: Students use technology tools to enhance learning, increase productivity, and promote creativity.
Assessment/Rubrics	Observation and questioning throughout the lesson to ensure that the students understand the material and can complete the assignment. Observation will focus on the following: n Students understand the connections between programming, geometry, and video game development n Students understand how VRML code determines the size and color of the shapes you create n Students can create new shapes by making minor adjustments to the code they have just typed n Students can change the size and color of their shapes by making minor adjustments to the their code n Students understand the importance of details and exactness in programming
