The critique argues that the Standard Behavior Chart is a technically adequate and useful measurement tool. (JDD)

This article responds to a criticism (EC 231 964) of a paper that discusses graphs for measuring progress on individual education plans (EC 210 837). It notes that the type of chart used is not a major issue; the important point is that teachers repeatedly gather data on educationally relevant tasks and evaluate intervention effectiveness. (JDD)

For 83 low-achieving elementary students, predictions of future performance were computed on the basis of reading and written expression data and were subsequently compared to actual data. Analyses indicated that predictions were more accurate when the data had been graphed on equal interval graphs rather than semilogarithmic charts. (Author/JDD)
