Describes a seventh-grade science process skills test entitled, "In Hot Water." Students respond in writing to a hypothetical problem and then are provided with a model response. Students apply this model response in their performance of subsequent skills. The assessment can be used for individual or group work. (PR)

Describes how students' social skills can be assessed in the context of cooperative learning. Suggests that the following classroom protocols be assessed: (1) listen; (2) be responsible to others; (3) respect others; and (4) stay on task. Provides an assessment scale for these behaviors. (PR)
