Research Aim Examine effects of two different methods of providing expert coaching to teachers on instructional practices Goal of intervention is to improve Head Start classroom and teacher supports for literacy and language development, and childrens language and literacy skills
Expert Coaching Increasingly used as a professional development strategy Includes components recommended in the in-service teacher education literature: –guided implementation of research-based knowledge in classroom practices –individualized delivery –immediate feedback, including analysis of teaching
Role of Technology Technology is an emerging resource in early childhood professional development Viewed as a potentially economical alternative to on-site coaching, particularly for supporting teachers in geographically remote locations Research on effects of technologically- delivered expert coaching is limited
Two Forms of Technology Developed in Current Project Video review tool –Supports critique of videotaped teaching practices submitted by teachers –Used by coach to divide videotaped teaching sample into segments –Coach provides constructive feedback and suggestions on each segment of instruction –Teacher views critique on split screen: segments on left, coach comments on right
Two Forms of Technology Developed in Current Project (cont.) Case-based hypermedia resource –16 cases on how teachers can improve childrens early literacy outcomes –Each case is comprised of video clips of research-based practices plus text that highlights key practice elements practitioner-oriented articles on case topic references to research and other resources links to related cases in hypermedia resource –Links to cases are embedded in coach comments to teachers
Research Design 84 Head Start classrooms in 29 centers randomly assigned to fall or to spring intervention semester Classrooms assigned to spring intervention semester served as control classrooms in fall semester Within each intervention semester, classrooms randomly assigned to on-site or to remote coaching condition
Research Design (cont.) Teacher, classroom, and child outcome data collected before and after intervention semester plus follow up (one-semester post intervention) in fall semester intervention group Teacher/classroom measure: ELLCO Child measures: PPVT, WJ-LW, letter naming, blending
Intervention Two-day workshop prior to intervention semester Remote coaching condition –Critique of teacher-submitted videotape of instruction (M=22 mins) plus hypermedia resource On-site coaching condition –Critique of observed instruction (M=105 mins) provided in one-on-one consultation (M=32 mins) as part of visit to classroom Approximately twice monthly contact in each condition
Sample (2005-2006 cohort) Head Start classrooms serving urban, small city, rural communities Teachers (n = 51) –82% associates or bachelors degree –Median of 3.0 years in current position –No statistically significant background differences between semester or condition Children (n = 470) –27% Latino, 37% African American –4 years of age by December 31
Classroom Instruction Outcomes Intervention and intervention X time differences on ELLCO overall and language-literacy instruction: Both intervention groups had greater gains than control Effect sizes were substantial (approximately d = 1.0)
Child Outcomes Children in intervention groups scored higher and made greater gains on measures of letter and word identification, naming letters, and blending than children in control group Effect sizes were moderate (approximately d=.23) No differences in outcomes between the two intervention conditions
Feedback and Suggestions by Coaching Condition: Amount Preliminary analyses of coaching sessions (n=60) in randomly-selected classrooms (n=8). (Coaches were assigned to both on-site and remote conditions.) Coaches provided feedback/suggestions on more topics in remote than in on-site condition. Coaches offered about twice as many feedback statements and suggestions in remote than in on-site condition.
Amount of Feedback/Suggestions Per Contact Remote M (SD) On-site M (SD) Topics9 (3.2)5 (1.5) Feedback Statements5 (2.5)2 (0.7) Suggestions6 (2.6)3 (1.6)
Feedback and Suggestions by Coaching Condition: Content Higher percentage of coach comments in: –on-site related to literacy materials –remote related to individualization of teaching practices. The percentage of coach comments related to literacy teaching practices for all children was similar across the two coaching conditions.

Rethinking Our Starting Point Original premise: A technologically- mediated method of coaching may be an effective alternative to the dominant (on- site) method of coaching. Revised premise: Technologically- mediated and on-site methods of coaching may provide distinctive, complementary contributions to improvements in teacher quality.
