| Abstract | In light of the need to close the achievement gap among our culturally and linguistically diverse students, more specifically the Hispanics and the Hispanic English Learners (ELs), the effects of teacher professional development (2 year PD vs. 1 Year PD vs. no PD) on the implementation of a standards-aligned and inquiry-based science curriculum program - the Integrated Coordinated Science for the 21st Century published by It's About Time, Inc. (ICS-IAT) -- on the LAUSD ninth graders science scores were examined. Participants included 8,937 9th grade students (7,356 Hispanics). The primary outcome measurement was scaled scores from the California Standard Test (CST) in Integrated Coordinated Science (CST_ICS1). Correlations between California English Language Development Test (CELDT) component subscores (reading, listening and speaking) and CST scores were also examined.; Results indicated that the science scores of the students of teachers who participated in two year PD were significantly higher compared to the scores of students of the one year PD group and the control group. The results show that all ethnic groups benefited from two years of teacher PD, except the African American group. Among Hispanics, students classified as IFEP, RFEP and EO gained from the teachers having two years of professional development. But the target population, ELs did not benefit from two years of teacher PD.; The correlations between the CELDT and CST_ELA were much higher than the CELDT and CST_ICS1 correlations. This finding validates Abedi's claim (2004) that EL students are disadvantaged because of their language handicap on tests that have a greater language load.; Two year PD participation significantly enhanced the accessibility of science to the ninth graders. The essential features in the PD were classroom simulation of all the activities identified in the storyboard with the actual and correct use of needed equipment and materials; creation and presentation of sample or model Chapter Challenges; practice on the use of the storyboard; facilitation of activity debriefs using a debrief template; and the use and practice of identified strategies and scaffoldings targeting ELs. Three innovations developed by the LLAUSD-ICS Leadership Team also were introduced in the PD sessions. They are the storyboard, "cartoon analysis" and debrief template. |
