Coaching in Literacy Collaborative and Its Effects on Teachers and Students Gina Biancarosa, University of Oregon Anthony S. Bryk, Carnegie Foundation for the Advancement of Teaching Allison Atteberry, Stanford University Heather Hough, Stanford University Annual Meeting of the Society for Research on Educational Effectiveness March 2010
2
Key Features of Literacy Collaborative Comprehensive school reform program designed to improve elementary children’s reading, writing, and language skills primarily through school-based coaching Used in over 700 elementary schools in 200 districts across 26 states Intensive professional development – Coaches trained over one year (Lesley University and the Ohio State University) – Ongoing support from local and national network Coaches – In-school professional development courses – One-on-one coaching: viewed as the high leverage activity

Anatomy of a coaching session – Pre-briefing – Observation – Modeling – Debriefing Elements of literacy instruction – Interactive read aloud – Shared reading – Guided reading – Interactive writing – Writing workshop – Word study Key Features of Literacy Collaborative
4
Main Research Questions Does Literacy Collaborative improve the value-added to student literacy learning? Can any effects of Literacy Collaborative be indirectly attributed to coaching via teachers’ changing expertise implementing the instructional practices? Can any effects of Literacy Collaborative be directly attributed to coaching? – Does overall coaching activity in a school predict value- added to student literacy learning? – Does individual teacher participation in coaching predict value-added to student literacy learning?
5
Student Data Value-added analyses focused on grades exposed to LC professional development (K-2) Sample: 8576 children, 341 teachers, and 17 coaches in 17 public schools across 8 states in the Eastern U.S. Children tested in fall and spring for 4 years to measure change over time in students’ literacy learning using: – Dynamic Indicators of Basic Early Literacy Skills (DIBELS) – Terra Nova in spring Low Income46.0% Race/Ethnicity African-American Latino Other White 15.5% 5.8% 7.2% 70.6% Limited English Proficiency4.0%

Our early literacy scale Equal differences on scale imply equal differences on the trait measured at any level Reported in logits (which describe the probability of a student with a given ability level getting a particular item right or wrong) But what do they mean given the particular assessments used? 1 2 3 4 Mean at K entry Names about 30 letters in a minute Very low phonemic awareness (PA) Mean at K end & 1 st grade entry Accurate and fast letter recognition Good initial sound PA Little evidence of decoding Mean at 1 st grade end & 2 nd grade entry Accurate (not fast) PA Reads 50-60 wpm Answers 1/3 of 1 st grade comprehension questions correctly Mean at 2 nd grade end Mastery of component skills Reads 90 wpm Answers 2/3 of 1 st grade comprehension questions correctly, 1/3 of 2 nd grade questions correctly

Value-added Hierarchical Cross- classified Effects Modeling Four Levels – time : (students x teachers) : school – Repeated measures on students (level 1) – Students (level 2) who cross Teachers (level 3) over time – All nested within Schools (level 4) The analysis model can be conceptualized as a joining of 2 separate multi-level models – One two-level model for individual growth in achievement over time, and – A second two-level model which represents the value-added that each teacher in a school contributes to student learning in that school in a particular year.

Explaining variability in value-added effects Tested models with cumulative number of coaching sessions per year (derived from coach logs) – Per teacher – Averaged across teachers at school-level Also tested a variety of controls thought to influence teachers’ openness to, participation in, and selection for coaching – Prior use of reform literacy practices – Role conception – School commitment – New to school

Summary of findings Evidence that the mechanism for improved value- added shifts from over time – Year 1: Coaching has no value-added – Year 2: Coaching begins to add to value-added for student learning – Year 3: Coaching becomes the primary mechanism for value-added to student learning Cumulative coaching explains differences in teacher value-added effects, but not school effects
31
Implications Coaching explains differences in teachers’ value- added to student learning Shift in coaching effects from negative in Year 1 to positive in Years 2 and 3 raises interesting hypotheses but offer no answers – A selection effect (on the part of coach or teacher) – A dosage effect – A change in coaching expertise effect – Unexplored school/coach effects Direct positive effects of coaching on students appear to take time to emerge
32
Limitations Limited sample, especially at school level, limits ability to explore contextual mechanisms Coaching was embedded in a school-wide reform model Professional development for coaches is more intense than in most other models
33
Future Steps Continued analyses of current data – Length of coaching session – Focus of coaching session – Observation vs. modeling Development and piloting of the Performance-based Assessment of Literacy Coaching (PALC)
