Figure 5.

Scatter plots reveal increases in individual student's KI scores after using Science Skills instruction and assessment tools. (A) Comparison of pre- and midassessment scores for each student. (B) Comparison of pre- and postassessment scores for each student. Data points were jittered in the R Software Environment so that all were visible. A red line with a slope of 1 indicates no improvement; points above the line indicate increased improvement; points below the line indicate decreased improvement. Note that the data set is the same as that analyzed in Table 2 and Figure 4.
