Rating: (1-5)

Relevance to objectives: 4, Clear and precise.  You definitely get good practice on your math facts!
Provides practice of relevant skills: 4, Allows the player to adjust the level of game that is played.  Can go from very easy to hard (even for a college student).
Likely to arouse/maintain interest: 2,  It is pretty straight forward but not enough graphics to keep the attention of the student. When you get done with a section it states "you get a star".  Actually putting a star on the screen would be nice.
Likely to be comprehended clearly: 4,  It is very easy to understand. There is step by stap instructions/directions for the student to follow.  It is easy to get going on the game without many instructions.  Some kids may find it hard to type in the answers quick enough even if they know the answer.
Technical quality (durable, attractive): 2.  Not very attractive,  Sound and graphic effects are weak. This seems like a game from about 5-10 years ago.  The main emphasis is on the math, but kids can get that in school.
Game: Winning dependent on player actions (rather than chance):  Given there is two players it scores the total time taken to complete the round.
Simulation: Validity of game model (realistic, accurate depiction):5, Not really a game but it does allow you to  compete for time.  Makes you feel as if you are on a game show.
Evidence of effectiveness (e.g. field-test results): My 7 year-old  daughter enjoyed the game, but in the end she got bored. The quizzer was repetitous and not to appealing to her.  She, as most 7 year-olds are these days, is used to more graphics and fun in games.
Clear directions for play: 5,  Instructions were clear and understandable.
Effectiveness of debriefing: 5,The practicing of the quizzer will allow the students to learn more about time quality and improve the math skills.  You have to know the facts backward and forword to get the answer in on time.
