The purpose of this study was to determine the effectiveness of East Tennessee State University's summer science institute training through the effect on mean Normal Curve Equivalent science test scores of students in a Northeast Tennessee school system whose teachers participated in the ETSU summer science institute training. Data analysis were compiled using students' science NCE scores to determine if there were significant differences in scores for those students whose teachers participated in the summer science institutes and those who did not participate. Students' NCE scores were compiled from the middle school setting over a 3-year academic period: 2004-2005, 2005-2006, and 2006-2007. Paired-samples t tests were used to analyze the effectiveness of teacher participation by comparing preparticipation and postparticipation students' science NCE scores for years 3 years. Independent-samples t tests were used to compare students' gender, socioeconomic status (free- and reduced-price meals), and NCE science scores (using 5th grade only) for 2 consecutive years of the study (2005-2006 through 2006-2007). Two analyses were used to determine teachers' participation and the effect on students' NCE science scores among two subgroups: gender and socioeconomic status. For research questions 4 and 5, a mean net gain and NCE raw scores average was performed.
The findings from this study indicated significant differences in years 2004-2005 and 2006-2007 favoring students of teachers who participated in the summer science institutes However, the results from year 2005-2006 showed no significant differences in students' science NCE scores of teachers who participated or did not participate in summer science institutes. In the consecutive year (2005-2006 through 2006-2007) using 5th grade only comparisons, data analyses showed significant differences in students' science NCE scores when performing NCE raw scores comparisons for gender and socioeconomic status. The comparisons for gender showed male students' science NCE scores were higher than were females' science scores. The NCE raw scores comparisons for socioeconomic status showed those students on the meals program had higher science NCE scores than did those students not on the program. There was no significance in students' science NCE scores when using mean net gain scores comparison for gender and socioeconomic status.
