Examined the world views of children after they had experienced a natural disaster, Hurricane Andrew, in Florida in 1992. Responses of 127 fourth and fifth graders indicated differences and similarities in the children's world views by ethnicity, socioeconomic status, and gender. Discusses implications for promoting science literacy for all…

Identifies and quantifies the chemistry conceptions used by students when solving chemical equilibrium problems requiring application of LeChatelier's Principle, and explores the feasibility of designing a paper and pencil test to accomplish these purposes. Eleven prevalent incorrect student conceptions about chemical equilibrium were identified…

Observed Hindi-speaking Indian caregivers and their children to examine how caregivers use language to create diverse conceptions of personhood. Distributional analyses examined the proportion of person references and class-based patterns of co-occurrence between particular social acts and person references. Discussion explored ways in which…

Argues that mathematics literacy begins at birth and that all that children need to construct mathematics concepts for themselves are a stimulating environment and receptive adults. Provides suggestions for promoting emergent math for children from birth through 4 years, including using rhythm and music, incorporating mathematics concepts into…

Two experiments were conducted using match-to-sample methodologies in an effort to model lexical classes, which include both arbitrary and perceptual relations between class members. Training in both experiments used a one-to-many mapping procedure with nonsense syllables as samples and eight sets of abstract stimuli as comparisons. These abstract…

The value of conceptual physical education knowledge has long been acknowledged (American Alliance for Health, Physical Education, and Recreation, 1969; Kneer, 1981; NASPE, 1995) yet has not been formally measured or assessed. Seven multiple choice tests with established validity and reliability (Ayers, 2001b) were used to assess the concepts…

Web-based peer assessment is an innovative method that can be used to assess students' learning portfolios in order to improve their learning. However, students cannot easily compare their own evaluation schemes or think reflectively to improve their learning through web-based peer assessment if they do not understand how others perceive the…

This paper reports a cross-sectional study of Taiwanese physics students' understanding of subatomic phenomena that are explained by quantum mechanics. The study uses students' explanations of their answers to items in a questionnaire as a proxy for students' thinking. The variation in students' explanations is discussed as is the development in…

This study explores general-chemistry instructors' awareness of and ability to identify and address common student learning obstacles in chemical equilibrium. Reported instructor strategies directed at remediating student alternate conceptions were investigated and compared with successful, literature-based conceptual change methods. Fifty-two…

As the study of student connection to school has expanded, so too has the lexicon of terms, concepts, and measurement tools. In summarizing the literature to guide current practice and future research, the various terms and definitions need clarification. The intent is not to settle on a single term, though agreed on language may benefit future…

This article presents and discusses some results of the authors' analysis of international and national institutional documents related to environmental education from the 1970s to the present day. The aim of the study is to present a critical characterization of how environmental education is conceptualized and introduced through the ongoing…

Constructivism, as a set of theories about how learners learn, has been an important discourse in the educational research literature for a number of years. Interestingly, it has been far more visible in science education research than in environmental education research. This article considers conceptual change theory within constructivism as a…

Recent advances in genomics and structural biology have resulted in an unprecedented increase in biological data available from Internet-accessible databases. In order to help students effectively use this vast repository of information, undergraduate biology students at Drake University were introduced to bioinformatics software and databases in…

This paper proposes a methodology to calculate both the difficulty of the basic problems and the difficulty of solving a problem. The method to calculate the difficulty of problem is according to the process of constructing a problem, including Concept Selection, Unknown Designation, and Proposition Construction. Some necessary measures observed…

The study examined (a) the extent to which teachers and preservice teachers understand the concept of energy and adhere to particular preconceptions associated with it; and (b) their ability to predict pupils' knowledge and understanding of the same concept. Teachers and preservice teachers completed a test by indicating for each item what their…
