Combo codes have been developed to allow an instructor to, with a single three digit code, to simultaneously modify
[A] the performance threshold, [B] the number of trials, and [C] available decision time, or
[A] the performance threshold, [B] the number of trials, and [C] the number of rounds.
A Combo code does not have the flexibility of using individual modification codes, but to use a Combo code (just three digits) rather than typing in three modification codes (nine digits) can be nice - especially if the digits are being entered by the player by hand.
6## - Performance, Trials, & Decision Time
First, choose a performance threshold: 80% (0), 85% (20), 90% (40), 95% (60), or 100% (80).
Then the number of trials: 10 (0), 20 (4), 30 (8), 40 (12), 50 (16).
Finally, the decision time in seconds available to the player: unlimited (0), 1.0s (1), 2.0s (2), 3.0s (3).
Take your three selections, and add up the values associated with them shown in parentheses. So, for an accuracy threshold of 85% (20), with 30 trials (8), with 3.0s (3), that would sum up to 20 + 8 + 3 = 31. The Combo code would be 631.
7## - Performance, Trials, & Decision Time (Continued)
First, choose a performance threshold: 80% (0), 85% (20), 90% (40), 95% (60), or 100% (80).
Then the number of trials: 10 (0), 20 (4), 30 (8), 40 (12), 50 (16).
Finally, the decision time in seconds available to the player: 4.0s (0), 5.0s (1), 6.0s (2), 7.0s (3).
Take your three selections, and add up the values associated with them shown in parentheses. So, for an accuracy threshold of 90% (40), with 20 trials (4), with 5.0s (1), that would sum up to 40 + 4 + 1 = 45. The Combo code would be 745.
8## - Performance, Trials, & Rounds
Choose a performance threshold: 80% (0), 85% (20), 90% (40), 95% (60), or 100% (80).
Then the number of trials: 5 (0), 10 (4), 15 (8), 20 (12), 25 (16).
Finally, the number of rounds: 1 (0), 2 (1), 3 (2), 4 (3).
Take your three selections, and add up the values associated with them shown in parentheses. So, for an accuracy threshold of 100% (80), with 5 trials (0), and 4 rounds (3), that would sum up to 80 + 0 + 3 = 83. The Combo code would be 883. In this example, the completion code would only be provided after four games (of 5 trials each) were completed, each with 100% accuracy.
The Combo Codes are applied first to a game (6##, then 7##, then 8##), after which the individual modification codes are applied. Thus, you could provide the code 631 (for an accuracy of 85%, 30 trials, and a decision time of 3.0s) and follow that up with 250 (to update the decision time of instead be 5.0s), so that the code would look like this "631250". Though ideally the single Combo Code would accomplish it all.
If you will be requiring students to provide a modification code to adjust play of a game, it may be convenient for the student to provide the passcode and modification code all at once.
To do this, the student would first type in any modification codes (include Combo codes), followed by a dash, the passcode, and finally any accommodation code.
So, if the Combo code 631 is used (for an 85% threshold, with 30 trials, and 3.0s decision time), it could be combined with the passcode (e.g., 2288), to be "631-2288"
The student would enter the entire string using the Accommodation dialog box, and this would both modify the game appropriately and specify the passcode up front. Then, at the end of a successfully completed game, the related completion code would be presented to the student.
Finally, if accommodations are allowed, the student might request unlimited time, using the accommodation code of #17, and thus type in "631-2288#17" (resulting in a completion code that is slightly off from the actual completion code by +/- 2 points).
