Psychological Science Faculty Works
Using online problem-solving tasks and machine learning tools, a measure has been developed to quantify the effectiveness and efficiency of students’ problem solving strategies. This measure can be normalized across problem solving tasks allowing the efficiency of problem solving to be measured across individuals, classes, schools and science domains. This extensible approach has relevance for helping teachers to teach, students to learn, and administrators to make intelligent, data-driven decisions via documentation of students’ problem solving progress.

Heads Up!
Electronic versions of questionnaires have the potential to improve research and interventions in the addictions. Administering questionnaires electronically to groups, however, has proven difficult without a multitude of computers, but gathering data electronically from a group could make for easy assessment and quick feedback. Using a sample of 107 college students, we examined the validity of wireless keypad survey responses by comparing them to traditional paper-and-pencil questionnaires. The two formats led to almost identical responses that did not differ significantly from each other (all effect sizes less than g =.15) and high correlations between formats. The wireless, handheld keypad procedure …

Heads Up!
As part of a larger intervention study, the authors hypothesized that change rulers created for alcohol and safer sex would be equivalent to longer questionnaires. Ninety-six male college students completed rulers and questionnaires for assessing behavior change readiness. Participants' scores on the rulers significantly correlated with their scores on the questionnaires (r = .77 for alcohol; r = .77 for safer sex). In both domains, the rulers outperformed the questionnaires in predicting behavioral intentions, suggesting that the rulers had at least comparable concurrent criterion validity. This finding is the first of its kind in the safe sex literature and suggests …
