Relevance to objectives: 5-Since it is a self paced tutorial program, the student may proceed the review lessons as quickly or as slowly as desired.  Each question is compiled based upon previously learned material and the student cannot proceed until successfully answering the questions.
Provides practice of relevant skills: 5-Absolutely provides repetitive (drilling) of chemistry periodic table which is a prerequisite to further learning.
Likely to arouse/maintain interest: 4-Only if student is interested in the subject.
Likely to be comprehended clearly: 5-Yes since each question is a precept to the following.
Technical quality (durable, attractive): 5-A very well organized, both with factual information, and style/artistic quality of presentation.
Game: Winning dependent on player actions (rather than chance): 3-This is not programmed to be a game, but the lessons do reinforce the student by encouraging correct responses.
Simulation: Validity of game model (realistic, accurate depiction): 3-The simulation is relevant to scientific equations.
Evidence of effectiveness (e.g. field-test results): Received top rating from ZDNet
Clear directions for play: 5-Very simple directions.  If student is not answering correctly, the moderator instructs the student to go back and review.
Effectiveness of debriefing: 5-Encourages the student when lessons are successfully completed and since the program is based upon previous precepts learning various science subjects should transpire.
