Finding 1

• The number of professional development hours in which a student’s science teacher participated was a small but significant predictor of student performance on the science WASL above and beyond what could be explained by socioeconomics (FRL) and the student’s skill level (previous math WASL).

• This finding is consistent with earlier studies.

Finding 2

• Grade 5 teachers must have participated in at least 18 hours of professional development before an impact on student achievement was measurable, and the impact of the professional development on student achievement increased as the number of professional development hours increased.

Finding 3• Grade 5 teachers who had participated in

science professional development served:– A larger proportion of students eligible for free

or reduced-price lunch;– A greater proportion of Hispanic and Latino

students; and– A smaller proportion of White students.

• These differences may account for the differences in student achievement.

Module-Level Assessment of Student Content Knowledge • Evaluation Questions

– What science content knowledge gains do students make as a result of their use of the inquiry-based instructional modules?

– What is the relationship between the science PD of the teacher and the gains in student content knowledge?

17

Module-Level Assessment of Student Content Knowledge

• Assessment– Obtained Permission to use Horizon Research

Assessment– Selected Horizon Research Instruments

• Human Body from FOSS• Levers and Pulleys from FOSS• Rocks and Minerals from STC• Electric Circuits from STC

18

Module-Level Assessment of Student Content Knowledge

• Administration Plan– Recruit teachers with a range of PD levels– Data collection for each student

• Pre and post student scores• Student demographics

– Gift certificate compensation to teachers– Data collected spring 2008

• 53 classes completed both pre and post assessments• 1087 students

Finding 5• The relationship between student performance and teacher

professional development was inconclusive.– The performance of the students whose teachers participated in

fewer than 18 hours of professional development was significantly lower than the performance of students whose teachers participated in 18 or more hours professional development.

– Students whose teachers did not participate in professional development outperformed students whose teachers participated in some professional development.

• Additional data will be collected during the 2008–2009 school year.

Student Assessment Gains as a Function of Professional Development

24

Sentinel Site Selection• Schools With Significant LASER Participation• Identified 36 Schools

– 13 Schools Refused Participation– Added 11 New Schools

– Visited 34 Schools

• Defined 2 Groups of Schools Based on Science WASL Change Between 2006 and 2007 – Demonstrated Significant Positive Gains– Demonstrated Little, No, or Negative Gains

25

Sentinel Site Visits• 10 Site Visitors• Each site visit: 1 ½ to 2 days

– Principal Interview– At Least 5 Teacher Survey & Interviews– At Least 3 Classroom Observations

• Data Collection Instruments– http://www.rmccorp.com/LASERSiteVisits/

• Conducted 3 web-based training session• Round 1: Spring 2008• Results Reported As Rubric Scores

26

Finding 6• The site visitors gave the vast majority of the

schools visited very high ratings in several areas indicating that the schools served by the LASER Alliances had:– Successfully established a core sequence of inquiry-

based instructional modules across all of the grade levels, and

– Had materials support system that delivered modules to teachers on time and ready to use.

27

Finding 7

• There were several significant differences between schools whose students demonstrated increased performance on the science WASL compared to schools whose students did not.

28

Schools with Grade 5 Students• Schools whose Grade 5 students’ science

WASL scores increased had significantly greater:– Participation in professional learning communities– Time during the workday for school-based

professional development– Evidence of positive parent and community support– Evidence of teachers integrating literacy with science

29

Schools with Grade 8 Students• Schools whose Grade 8 students’ science WASL

scores increased had:– Time during the work day for school-based professional

development– Greater participation in professional development that

involved examining student work– Lessons that more often engaged students in

discussion based on scientific evidence– Lessons whose content was more significant, accurate

and worthwhile

30

Schools with Grade 8 Students (cont.)• Schools whose Grade 8 students’ science WASL scores

increased had:– Lessons that more often built on prior ideas and

experiences– Lessons whose content was more closely connected to

the lesson activities– Lessons that were effective at fostering student

understanding– Lessons that included mechanisms to monitor students’

understanding of science content– Lessons that helped students make sense of scientific

concepts– Lessons that routinely provided opportunities for students to

reflect on their new understanding

31

Finding 8• The schools that demonstrated an increase in the

percentage of students who met the science standards had teachers with significantly fewer years of education experience than the schools with no gains.

• This difference was more pronounced in the schools that served Grade 8 students.

– Testing for demographic differences between the schools that improved their science WASL scores and schools that did not could not account for the findings. Factors examined include:

• School size• Ethnic/racial composition of the student population• Program membership of the students• Teacher education and experience

32

Conclusion• The infrastructure to support the use of a core

curriculum of inquiry-based science instructional modules is in place and is functioning adequately in the schools visited.

• Although these conditions are necessary for the implementation of inquiry-based science instruction, they are not sufficient to raise student achievement as measured by the science WASL.

33

Recommendation 1• Ensure that the professional development on

research-based instructional practices is consistent and explicit across all of the LASER Alliances– Help teachers understand the elements of effective

science instruction and use the modules as a means of carrying out the element with their students.

34

Elements of Effective Science Instruction• Intrinsic Motivation

– Relevant, interest to student, resolution of dissonance• Eliciting Student’s Prior Knowledge

– Articulating what they already believe about a concept• Intellectual Engagement

– Students do the thinking• Use of Evidence

– Discourse: Justifications and explanations based on evidence• Sense-Making

– Closure, meta-cognition, reflection

Banilower, E., Cohen, K., Pasley, J., & Weiss, I. (2008). Effective science instruction: What does research tell us? Portsmouth, NH: RMC Research Corporation, Center on Instruction.

35

Recommendation 2

• Increase support for school-based professional development that helps teachers:– Assume accountability for student learning

that results from the use of the modules, and

– Collaboratively implement the elements of effective science instruction.

– Ample structure and leadership for success

36

Evaluation Activities for 2008-09• Sentinel Site Visits (30 to 35)• Student Content Assessments

– Fall, Winter, & Spring– 7 Instructional Modules

• Analysis of 2008 WASL Data• Online Surveys

– School Principal Survey– Alliance Directors

• PD Provider Online Surveys (3)

ASK-IT Schools Show What Science Engaged Schools Can Do

ASK IT schools had teachers who: Used formative assessment to

determine student understanding of key concepts

Met in professional learning communities to inform their teaching based on student data

Increased their science teaching time so most teachers completed each unit.
