A six-month longitudinal study (N = 33) proved the influence of a diversified sport enrichment program on the development of creative thinking in team ball sports among gifted children. A contrast between a gifted control group and a non-gifted treatment group showed that the creative performance of the gifted children significantly improved…

This report is part of a long-term research on the construction of mathematical meanings through the interaction with various technologies. The research involved a set of teaching experiments based on body motion with sensors and calculators at different school levels, from kindergarten to secondary school. Here I refer to the one developed in a…

We report four experiments designed to determine whether visual information affects judgments of acoustically-specified nonspeech events as well as speech events (the "McGurk effect"). Previous findings have shown only weak McGurk effects for nonspeech stimuli, whereas strong effects are found for consonants. We used click sounds that…

Malathion is an organophosphorus insecticide, which is often sprayed to control mosquitoes. When applied to aquatic habitats, malathion can also influence the embryogenesis of non-target organisms such as frogs and fish. We modified the frog embryo teratogen assay in "Xenopus" (FETAX), a standard toxicological assay, into an investigative…

This experiment was designed to help students improve the critical thinking skills that are required to analyze and discuss the results of an organic chemistry experiment in an effective manner. The initial objective indicated in the prelab handout for this puzzle experiment was the synthesis of methyl 4-bromobenzoate using the Fischer…

Attitudinal data tested hypotheses that students have more positive attitudes toward science when teachers regularly emphasize hands-on laboratory activities and when students more frequently experience higher levels of experimentation or inquiry. The first predicted that students would have more positive attitudes toward science in classrooms…

Hands-on science typically uses physical materials to give students first-hand experience in scientific methodologies, but the recent availability of virtual laboratories raises an important question about whether what students' hands are on matters to their learning. The overall findings of two articles that employed simple comparisons of…

In this article, the authors trace the emergence of an institutional discourse of ethical research and interrogate its effects in constituting what ethical research is taken to be and how ethical researchers are configured. They illuminate the dissonance between this regime of truth and research practice and the implications for the injunction to…

This article analyses change of time use and time allocation in three schools participating in a Swedish five-year national experiment in which State regulation of teaching time was weakened. Participating schools could freely decide how to use and distribute teaching time. The experiment was launched at a late stage in a 25-year decentralisation…

The Technology Enhanced Elementary and Middle School Science II project (TEEMSS), funded by the National Science Foundation, produced 15 inquiry-based instructional science units for teaching in grades 3-8. Each unit uses computers and probeware to support students' investigations of real-world phenomena using probes (e.g., for temperature or…

The aim of this paper was to describe the changes in one student's ideas about force and one-dimensional motion concepts and portray the relevant metaconceptual processes that she engaged in during the implementation of metaconceptual teaching interventions. Metaconceptual processes involves metacognitive processes that are directly acting on or…

We report on the construction and application of an instrument entitled the "Science Achievement Influences Survey" to assess combined effects of student attitudes about science, peer interaction, and home support, and the frequency of student-centred and teacher-centred instructional practices on student achievement. Controlling for pre-test…

Inquiry can be implemented in various ways, ranging from simple classroom discussions to longterm research projects. In this article, the authors developed a project in which high school students were introduced to the nature and process of scientific discovery through a two-week guided inquiry unit on "limnology"--the study of fresh water, which…

Science educators are often among the first to use emerging technologies in the classroom and laboratory. For the technologically savvy science teacher, the handheld computer is a terrific tool. A handheld computer is a portable electronic device that helps organize (via calendars, contact lists, to-do lists) and integrate electronic data…

We report a study of three prospective secondary science teachers' development of theories-in-action as they worked together in a group to explore collisions using both physical manipulatives and a computer simulation (Interactive Physics). Analysis of their investigations using an existing theoretical framework indicates that, as the group moved…
