Usability of the resource:Very usable Comments:Instructors who teach solid-state structure should find this a very useful program to use. Assumptions of model clearly stated:Yes Constraints on model clearly stated:Yes Adequate instructions provided:Yes Comments:This site provides a downloadable program which allows the user to visualize a number of crystal lattice types, elements, and compouds. The "help" file provides answers to the above questions. Rating:Excellent Comments:Easy to use program that has great graphics. Is there an instructor's guide:Yes Help easily available:Yes Student activities provided:No Site easy to navigate:Yes Comments:Great, easy-to-use site for use during lecture to help students see the 3D nature of simple materials. Could also be used by the student in a lab setting, or for homework. Usability Rating:Excellent Comments:Well-done graphics. Are pre-requisites identified:No Comments:The program contains an introduction to its contents in the "help" file and tells the user what is covered. Is the audience identified:No Comments:The program will be useful to use during discussion of solid-state structure at various levels. t ', 'Scientific/Proffesional', 'Educator', 'High School', 'College'] K-12 standards alignment provided:No Comments:No K-12 standards included. Necessary software referenced for lesson:Yes Necessary software referenced for model:Yes Links to free download information:Yes Comments:Freely downloadable program for Windows. Suggested improvements:No Comments:The program is well-done, provides a variety of viewing options, and should be used by those who cover solid-state structure. Material could be expanded to other grade levels:No Special arrangements made for disabled:No Special arrangements made for blind:No Special arrangements made for deaf:No

Usability of the resource:Very usable Code runs without problems:Yes Comments:Download was fast and installation was simple. Did the code crash:Never Comments:This is a downloadable program and is browser independent. Does the model require browser add-ons:Yes Comments:OpenGL graphics must be supported by the users system. Does the model require a specific operating system:Yes Comments:The download site specifies Windows 98, ME, 2000, or XP as the OS. Sufficient documentation to understand basics:Yes Sufficient documentation to select required inputs:Yes Sufficient to understand outputs:Yes Are the stated assumptions reasonable:Yes Based on known physical laws:Yes Derivations in model used correctly:Yes Does the model accept all inputs:No Model results consistent with documentation:Yes Did you run tests with experimental data:Yes Comments:The progam contains models of known compounds, and these models were of the correct structure. Comments:This program should find use by all who teach solid-state structure. Recommended improvements:None
