This study examined the problem of assessing group process in a collaborati
ve problem-solving situation. Students in seven collaborative groups worked
on a two-part math and logic problem-first individually, then in groups, a
nd finally, individually again. Groups engaging in behaviors that facilitat
ed collaboration obtained higher group and individual accuracy scores on a
challenging problem set. High-achieving students were influential in group
problem-solving outcomes. Group scares did not reflect the individual achie
vement of low-achieving students. Examining collaborative group process and
outcomes offers a new direction in functional and contextualized assessmen
t for school psychologists. (C) 2001 John Wiley & Sons, Inc.
