This article presents findings from an intervention across sixth and seventh grades to teach academic words to middle school students. The goals included investigating a progression of outcomes from word knowledge to comprehension and investigating the processes students use in establishing word meaning. Participants in Year 1 were two sixth-grade reading teachers and 105 students (treatment n = 62; control n = 43) and in Year 2, one seventh-grade reading teacher and 87 students (treatment n = 44; control n = 43) from the same public school. In both years, results favored instructed students in word knowledge, lexical access, and morphological awareness on researcher-designed measures. In Year 2, small advances were also found for comprehension. Transcripts of lessons shed light on processes of developing representations of unfamiliar words. [ABSTRACT FROM AUTHOR]

Does the race of interviewers introduce a bias in estimating the test score gap between blacks and whites in the United States? To answer this question, I use an adult sample from the General Social Survey (GSS) in which vocabulary testing involves face-to-face and one-on-one interaction between the respondent and the interviewer. I find that black respondents perform better when tested by a black interviewer as opposed to a white interviewer. For white respondents, however, the race of the interviewer does not have a significant impact on test performance. Because most black respondents are tested by white interviewers in the GSS, the test performance of black respondents is downward biased, and the black–white test score gap is overestimated.
