The purpose of this study was to understand if a STEM camp (Gear Up 4 STEM) offered during school breaks could improve science outcomes and engagement of elementary school students. This study followed two cohorts of students in Knox County Schools (grades 3, 4, and 5) over one school year and assessed their performance on the state administered…

Biology education plays a vital role in nurturing the understanding of learners about the intricacy of life. Various efforts have emerged to strengthen learning biological concepts but there were still studies that showed that learners have low mastery in some aspects. To determine how well students understood various biological topics, including…

This report leverages state educational agency data to explore the association between Alabama Science in Motion (ASIM) implementation and student outcomes. We conducted this study in Alabama to evaluate the potential of teacher implementation of ASIM lab activities to improve high school level student achievement in science. This study follows a…

The aim of this study is to reveal the opinions of teachers, who gave the science lessons that took effect in Turkey in 2004 and 2013, on the sub-components of the programs and to identify to what extent the objectives of the program have been achieved. In total 89 teachers, out of which 42 were females and 47 were males, in the study which was…

Even though school administrators and their leadership practices are rarely explored within science education research, our recent efforts to understand organizational influences on achievement disparities induced an elevated regard for elementary school principals. In this paper, we report on policy buffering by principals at schools whose…

Previous research has linked inquiry-based science instruction (i.e., science instruction that engages students in doing science rather than just learning about science) with greater gains in student learning than text-book based methods (Vanosdall, Klentschy, Hedges & Weisbaum, 2007; Banilower, 2007; Ferguson 2009; Bredderman, 1983;…

"Differential item functioning" (DIF) and "differential distractor functioning" (DDF) are methods used to screen for item bias (Camilli & Shepard, 1994; Penfield, 2008). Using an applied empirical example, this mixed-methods study examined the congruency and relationship of DIF and DDF methods in screening multiple-choice items. Data for Study I…

This study investigated the impact of an inquiry-based science program on the critical thinking skills, science process skills, creativity, and science fair achievement of middle school students. Although research indicates the connection between inquiry and achievement, there is limited empirical research relating specific inquiry-based programs…

This study investigated the effectiveness of a guided inquiry integrated with technology, in terms of female middle-school students' attitudes toward science/scientists and content knowledge regarding selective science concepts (e.g., Greenhouse Effect, Air/Water Quality, Alternative Energy, and Human Health). Thirty-five female students who were…
