This research explored the measurement characteristics of two science examinations and the potential to use access arrangements data to investigate how students requiring reading support are affected by features of exam questions. For two science examinations, traditional and Rasch analyses provided estimates of difficulty and information on item…

A field-based environmental geochemistry course was developed at Western Michigan University for undergraduate geosciences and environmental studies students to (1) improve student understanding of complex environmental systems, specifically targeting lake systems; (2) facilitate student development of professional-level, field- and…

Poor science achievement has been an educational issue for a number of years. Students with disabilities have traditionally fared worse. Research suggests that students with disabilities may respond better to instruction using an inquiry-based approach vs. traditional textbook instruction when measuring science achievement on standardized…

The integration of research and education is an essential component of our university's teaching philosophy. Recently, we made a curricular revision to facilitate such an approach in the General Chemistry Laboratory, to teach students that investigative approaches are at the core of sciences. The curriculum revision included new interdisciplinary…

Self-regulation is the controlling of a process or activity by the students who are involved in Problem solving in Physics rather than by an external agency (Johnson, 2011). Selfregulated learning consists of three main components: cognition, metacognition, and motivation. Cognition includes skills necessary to encode, memorise, and recall…

Significant momentum exists for next-generation assessments to increasingly utilize technology to develop and deliver performance-based assessments. Many traditional challenges with this assessment approach still apply, including psychometric concerns related to performance-based tasks (PBTs), which include low reliability, efficiency of…

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…

The purpose of this investigation was to explore students' epistemic beliefs and conceptual understanding of biotechnology. Epistemic beliefs can influence reasoning, how individuals evaluate information, and informed decision making abilities. These skills are important for an informed citizenry that will participate in debates regarding areas in…

This study reports the effects of student response systems (clickers) "versus" online homework on students' long-term retention of General Chemistry I course material. Long-term content retention was measured by a comprehensive yearlong American Chemical Society (ACS) GC97 exam administered seven months after students had completed the General…

Introduction: The study presented here explored the relationship between computer and Internet use and the performance on standardized tests by secondary school students with visual impairments. Methods: With data retrieved from the first three waves (2001-05) of the National Longitudinal Transition Study-2, the correlational study focused on…

This proposal advocates the position that the use of confidence wagering (CW) during testing can predict the accuracy of a student's test answer selection during between-subject assessments. Data revealed female students were more favorable to taking risks when making CW and less inclined toward risk aversion than their male counterparts. Student…

Several prominent scientists, philosophers, and scientific institutions have argued that science cannot test supernatural worldviews on the grounds that (1) science presupposes a naturalistic worldview (Naturalism) or that (2) claims involving supernatural phenomena are inherently beyond the scope of scientific investigation. The present paper…

This study examined the scores on a state standards-based Grade 5 Science assessment obtained by a group of students without learning disabilities who took the standard form of the test and by three groups of students with learning disabilities: one taking the standard form of the test without accommodations or modifications, a second taking the…

Using an innovative recruitment tool, the social network site Facebook, survey data were gathered from samples of the Australian general public and from around the world. Views on the gendering of mathematics, science, and ICT were gathered. In this paper we report the findings from six of the 15 questions on the survey, and only from respondents…

As part of becoming scientifically literate, students should come to appreciate epistemic aspects of science. Little research has been conducted on elementary students' epistemological beliefs specific to science education. This study offers insights into third-grade students' epistemological beliefs while paying attention to the intersection of…
