Quantifying Student’s Scientific Problem Solving Efficiency and Effectiveness
Ronald H. Stevens and Vandana Thadani

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.
