Reflecting a need to prepare students for working in diverse organizations, this document was developed to increase school officials' awareness of bias in instructional materials and help them select bias-free materials. A number of the examples illustrate situations dealing with diversity in the workplace. The guide is divided into three parts: guidelines and procedure for evaluating bias in instructional materials, bias awareness training worksheets, and bias awareness and procedure training course. Part 1 defines bias, explains why bias-free instructional materials are critical, and discusses dimensions of bias that must be considered. Presented next is a four-step bias review procedure that entails selecting appropriate materials, reviewing their quality, deciding whether they contain biases, and implementing the bias review decision. Examples of biasing elements and a bias review checklist are included. Part 2 contains a 23-item bibliography and sections about the following types of bias: gender bias; racial/ethnic bias; bias against physical, mental, or emotional disabilities; and socioeconomic bias. Included in each section are an overview of the bias, a list of slurs reflective of the particular bias, and training worksheets consisting of questions to help identify bias in materials. Part 3 is a training package consisting of trainer directions, handouts, and transparency masters for a 3- to 6-hour course preparing reviewers to use the bias review procedure and evaluation guidelines.
