Using qualitative data collection and analyses techniques, we examined mathematical representations used by sixteen (N=16) teachers while teaching the concepts of converting among fractions, decimals, and percents. We also studied representational choices by their students (N=581). In addition to using geometric figures and manipulatives, teachers…

Investigating predictors of environmental attitudes may bring valuable benefits in terms of improving public awareness about biodiversity degradation and increased pro-environmental behaviour. Here we used an evolutionary approach to study environmental attitudes based on disease-threat model. We hypothesized that people vulnerable to diseases may…

This article describes the development of the Redox Concept Inventory (ROXCI) as a measure of students' understandings and confidence of both the symbolic and particulate domains of oxidation-reduction (redox) reactions. The ROXCI was created using a mixed-methods design in which the items were developed based upon themes that emerged from…

The purpose of this study was to identify the perceptions of pre-service science teachers about using vee diagrams and preparing electronic portfolios in physics laboratuary course. 103 first grade pre-service science teachers who took general physics laboratuary course were the participants of the study. Pre-service teachers constructed vee…

Critics have been attempting to debunk the mythical retention chart at least since 1971. The earliest critics, David Curl and Frank Dwyer, were addressing just the retention data. Beginning around 2002, a new generation of critics has taken on the illegitimate combination of the retention chart and Edgar Dale's Cone of Experience--the corrupted…

The authors are attempting to set the record straight regarding the sources frequently cited in the literature of the mythical retention chart and the corrupted Dale's Cone. They point out citations that do not actually connect with relevant works; provide correct citations of sources that are often cited erroneously; add references for overlooked…

This article explores the ways faculty and student affairs professionals can impact the student experience, particularly for Students of Color. Experiences at two institutions illustrate how developing deeper relationships and broader perspectives make a significant difference not only for students, but also for those who teach and support them.…

Digital games offer an appealing environment for assessing student proficiencies, including skills and misconceptions in a diagnostic setting. This paper proposes a dynamic Bayesian network modeling approach for observations of student performance from an educational video game. A Bayesian approach to model construction, calibration, and use in…

California is in the middle of a nearly unprecedented period of change in the state's education system. Following voter approval of Proposition 30 in 2012, the Legislature adopted the Local Control Funding Formula (LCFF) in 2013. The LCFF upended the way California funds schools, redistributing revenues toward schools and school districts facing…

The global immigration of people has increased the call by governments for multicultural education. Across the globe, in country after country, multicultural education have come to represent the theory and practice to teach majority and minority citizens and immigrants and to explore issues of policy and practice as it relates to: ethnicity,…

Dual-process theories have been proposed to explain normative and heuristic responses to reasoning and decision-making problems. Standard unitary and dual-process theories predict that normative responses should increase with age. However, research has focused recently on exceptions to this standard pattern, including developmental increases in…

Conceptual change requires learners to restructure parts of their conceptual knowledge base. Prior research has identified the fragmentation and the integration of knowledge as 2 important component processes of knowledge restructuring but remains unclear as to their relative importance and the time of their occurrence during development. Previous…

We report on the development of an item test bank and associated instruments based on the National Research Council (NRC) K-8 life sciences content standards. Utilizing hundreds of studies in the science education research literature on student misconceptions, we constructed 476 unique multiple-choice items that measure the degree to which test…

The purpose of this study is to reveal the metaphors of primary school students (n = 362) relating to the concept of global warming. Data collected by completing the expression of "global warming is like..., because..." of the students were analysed by use of qualitative and quantitative data analysis techniques. According to findings of…

Despite the endangered status of the orangutan, very little research has sought to understand what people know about this species or the conservation challenges they face. As zoos are well placed to influence such understandings, the present study sought to explore knowledge following a visit to orangutan exhibits at three Australian zoos…
