Volume 1 of this sourcebook is a compendium of information about tests used to assess critical thinking, problem solving, and writing. It serves as a tool for people who want comparative data about the policy relevance of specific student outcomes measured in these areas. An interactive version of Volume 1 allows users to specify their areas of interest and create a customized search of assessment measures in the three domain areas. The tests described in Volume 1 are those that are designed to measure cognitive variables for traditional students. The compendium does not describe less traditional methods such as portfolios and competencies. In addition, the evaluations of the tests are based on the way test developers represent them in their materials and, in some cases, in information from third-part reviews. Volume 2 is a companion volume that provides eight case studies of institutions that have addressed related issues through the use of assessment methods in Volume 1. Volume 1 contains the following sections: (1) "General and Specific Issues in Selecting Assessments"; (2) "Critical Thinking and Problem Solving"; (3) "Templates--Critical Thinking and Problem Solving"; (4) "Writing"; (5) "Templates--Writing Commercially Developed Tests"; and (6) "Templates--Writing Locally Developed Tests." Volume 2 discusses the eight case studies and contains four appendixes providing details about the methodology. (Volume 1 contains 10 tables and 150 references.) (SLD)
