For Students, Faculty, and Staff: MyU One Stop

Pilot study

Since 2013, the research team has worked with teachers to develop, pilot, and refine the DBI-TLC professional development package.

A participating teacher shared...

The thing I really like about DBI is that I am the researcher. I can come to an IEP meeting and show the team, especially the parent, that the student is making progress with this intervention at this time. I like DBI because it helps me improve my practice. Instead of asking "What is wrong with the student?" I ask "What is it that I need to change, so that this student can make progress?"

Study findings

Findings from the pilot study, indicated that teachers who received DBI-TLC outperformed teachers who did not receive DBI-TLC in their knowledge and skills of data-based instruction.

Title: Pre-Post Growth on DBI Knowledge and Skills (Number Correct)

X axis: Pre-test and Post Test

Y axis: Teacher score 0.0 to 35.0 on Knowledge and Skills test.

A line is drawn from pre-test to post-test for six sets of data (Control MN, DBI-TLC MN, Control MO, DBI-TLC MO, Control Total, DBI-TLC Total). For all six groups, the teacher’s pre-test Knowledge and Skills performance was, on average, 25.0, on a scale of 0 to 40.0. At post test, control teacher’s Knowledge and Skills (MN, MO, and total groups) were slightly below 25.0, whereas teachers in the experimental group (MN, MO and total groups) average Knowledge and Skills were around 32.0. There was a significant difference of time p = .016 and Time by condition p<.001, with an Effect Size of 2.92.].

Though there were no statistically significant differences, students of teachers who participated in DBI-TLC outperformed, on average, students of teachers who did not participate as measured by writing tasks.

Research also suggested that, on average, students in the DBI-TLC group outperformed their peers in the control group on Curriculum-Based Measures at post-test. Differences between groups were non-significant in the pilot study, which may be due to the study being underpowered (small sample size).

X-axis: four categories are listed: of PW_WW (Picture Word: Words Written), PW_WSC (Picture Word: Words Spelled Correctly, PW_CWS (Picture Word: Correct Word Sequences), and PW-CIWS (Picture Word: Correct minus Incorrect Word Sequences).

Y-axis:Student score 0.0 to 30.0 on posttest CBM Picture Word

Within each category, two bar graphs are present, the left bar graph representing control and the right bar graph representing DBI. In all four categories, DBI-TLC students outperformed control, however, the differences were non-significant. PW_WW: p= .448, ES .225, PW_WSC = p= .435, ES = .232, PW_ CWS = .292, ES = .312, PW_CIWS: p = .279, ES = .328.]

Findings suggest that DBI-TLC appears feasible to implement in schools and holds promise as practice to promote student writing outcomes.
