More than half of U.S. children fail to meet proficiency standards in mathematics and science in fourth grade. Teacher professional development and curriculum improvement are two of the primary levers that school leaders and policymakers use to improve children's science, technology, engineering and mathematics (STEM) learning, yet until recently,…

Background: This paper discusses a framework for analyzing the dependence on mathematical theory in test items, that is, a framework for discussing to what extent knowledge of mathematical theory is helpful for the student in solving the item. The framework can be applied to any test in which some knowledge of mathematical theory may be useful,…

The purpose of this study was to investigate the relative effectiveness of experimenting with physical manipulatives alone, virtual manipulatives alone, and virtual preceding physical manipulatives (combination environment) on third-grade students' science achievement and conceptual understanding in the domain of state changes of water, focusing…

The purpose of this study is to examine students' perceptions of instructional practices in the classroom, and to further investigate the relationships among instructional practices, motivational beliefs and science achievement. Hierarchical linear modelling was utilised to examine the Trends in International Mathematics and Science Study 2007…

The focal course for this study, Pharmaceutics I, is a foundational course for the first year students (P1) enrolled in the in the PharmD program. It focuses on helping students create integrative bridges between the prepharm chemistry courses and the clinical courses in the PharmD curriculum. The main expected outcome of this course is that…

The study investigates teachers' classroom assessment practices of secondary schools in Bangladesh. The study is mainly quantitative with some integration of qualitative approach. Secondary science teachers and their science classrooms were main data source of the study, which were selected randomly. Data sources were secondary science teachers…

This study uses a quantitative content analysis of learning competences -- as described and prescribed in 21st century frameworks -- and those competences evaluated by international assessments to explore the nexus between recommendation and reality. In drawing insights from the theoretical underpinnings of human capital theory we argue, with…

A systems-based classroom intervention on environmental education was designed for seventh grade students; the results were evaluated to see its impact on the development of systems thinking skills and standard science achievement and whether the systems approach is a more effective way to teach environmental issues that are dynamic and complex. A…

This mixed method study investigated the extent to which the use of a model built around student-led questioning and feedback improved the learner engagement and attainment of a cohort of students. It compared outcomes from an experimental with a control group of students in Key-Stage 3 using a set of parameters. It found that the experimental…

The transition to college is challenging for most students, especially those who aspire to major in the science, technology, engineering, or mathematics disciplines, in which introductory courses can be large and instruction less than optimal. This paper describes a novel, disciplinary first-year seminar (FYS) course, Exploring Biology, designed…

Due to apartheid policies, Black African learners in South Africa have been severely disadvantaged in school science. Despite policy changes to redress these historical imbalances, Black African learners continue to underperform in science. Previous research has identified motivation as a key factor that impacts performance. Achievement goal…

This paper presents results from the evaluation of the Nurture thru Nature (NtN) programme, a natural science and environmental education intervention designed to help elementary school children from disadvantaged backgrounds increase their knowledge of science and strengthen overall academic performance. Using an experimental design the pilot NtN…

This study is motivated by two research questions: (1) How does Culturally Congruent Instruction (CCI) influence American Indian (AI) students' attitudes and achievement in natural resources science at a tribally controlled college/university (TCU)? And (2) What is the nature of the relationship between CCI course modifications and changes (or…

Section 29.182 of the Texas Education Code (TEC) makes provision for all students in the State of Texas to participate in Career and Technical Education (CTE) programs. CTE programs incorporate competencies that lead to the attainment of academic and technical skills, industry recognized certificates, licenses, and credentials for employment as…

Hierarchical linear models have become a familiar method for accounting for a hierarchical data structure in studies of science and mathematics achievement. This paper illustrates the use of cross-classified random effects models (CCREMs), which are likely less familiar. The defining characteristic of CCREMs is a hierarchical data structure…
