A qualitative case study was conducted to investigate the understanding of the limiting reagent concept and the strategies used by five Year 11 students when solving four reaction stoichiometry problems. Students' written problem-solving strategies were studied using the think-aloud protocol during problem-solving, and retrospective verbalisations…

Insects are ideal models for demonstrating an array of biological and ecological concepts and the application of biology to solve real-world problems. Integrating service-learning, a pedagogy bridging theory and practice, into the entomology curriculum at the University of Georgia provides students an opportunity to participate in developing and…

The aim of this study was, first, to investigate any pattern between students' quantitative contribution to argumentation and their science understanding, and second, to analyze any relationship between students' qualitative contribution to argumentation and their scientific knowledge. Participants of the study were four tenth-grade students. The…

This third article in a series describing survival analysis of engineering student retention and graduation introduces accelerated failure-time as an alternative to the Cox proportional hazards model to the context of student data. The new survival analysis of graduation data presented here assumes different distributions including exponential,…

Accompanying the rise in the number of working parents is a growing demand for after-school care schemes for children. After-school care schemes, in addition to school, provide pupils with more learning opportunities than the experiences that school provides. The hypothesis is that after-school care schemes offer a better knowledge-basis for…

Discovering what determines students' success in the Secondary Education Institutional Exam is very important to parents and it is also critical for students, teachers, directors, and researchers. Research was carried out by studying the related literature and structural equation modeling techniques. A structural model was created that consisted…

Recent calls for improvements in the teaching of science have supported the implementation of numerous reform strategies in the elementary classroom. Reviews of the different reform strategies have indicated varying levels of effectiveness. One method shown to be effective in producing changes in teachers, the teaching process, and student…

In this paper we combine the findings from two recent studies relating to participation and attainment in school science --a re-analysis of existing official data for England and a review of wider international research evidence in the literature relevant to the UK. Although the secondary data are drawn mainly from England, the comprehensiveness…

The purpose of this study was to better understand how an online, multimedia case study method influenced students' motivation, performance, and perceptions of science in collegiate level biology classes. It utilized a mix-methods design including data from pre- and post-test, student surveys, and focus group interviews to answer one primary…

This study examines the impact of the inclusive environment on student performance. As schools work to comply with the Least Restrictive Environment requirement of the Individuals with Disabilities Education Act, including students into the general education environment has become the norm as opposed to the exception. The improvement in…

The demands of national educational reforms require high school biology teachers to provide high quality instruction to students with and without special needs. The reforms, however, do not provide teachers with adequate teaching strategies to meet the needs of all students in the same context. The purpose of this grounded theory study was to…

In 2004, the National Center for Engineering and Technology Education (NCETE) secured funding from the National Science Foundation (NSF) to infuse engineering design into the schools through technology education. In order to reach this goal the researchers, in cooperation with NCETE, conducted a two phase study to identify outcomes for high-school…

The main goal of this study was to explore whether the use of multimedia in genetics instruction contributes more to students' knowledge and comprehension than other instructional modes. We were also concerned with the influence of different instructional modes on the retention of knowledge and comprehension. In a quasi-experimental design, four…

This paper reports a two-year longitudinal study of the effects of cooperative learning on science attainment, attitudes towards science, and social connectedness during transition from primary to high school. A previous project on cooperative learning in primary schools observed gains in science understanding and in social aspects of school life.…

In the move from elementary to middle school mathematics, students encounter major changes in instructional materials and approaches, work expectations, school structure, and general level of difficulty in material. Research shows that, in general, students suffer significant declines in academic achievement in the transition from elementary…
