The science and engineering practices in the "Next Generation Science Standards" seek to engage students in complex tasks including planning and carrying out investigations or engaging in argument from evidence. However, such tasks often require students to effectively collaborate. While our students get better at working together in an…

Two studies investigated the accuracy of eight different interval-based group observation methods that are commonly used to assess the effects of classwide interventions. In Study 1, a Microsoft Visual Basic program was created to simulate a large set of observational data. Binary data were randomly generated at the student level to represent…

Simulations and games offer interactive tasks that can elicit rich data, providing evidence of complex skills that are difficult to measure with more conventional items and tests. However, one notable challenge in using such technologies is making sense of the data generated in order to make claims about individuals or groups. This article…
