This study sought to find out if (a) the performance of 113 Jamaican 11th-graders on a mole concept test was satisfactory or not; (b) there were significant differences in their performance linked to their chemical and mathematical abilities, gender and socioeconomic background (SEB); and, (c) there were significant relationships among the four…

Kinetic models of a gas can be hard for students to understand. Typical tools do not display events at the microscopic level, yet computer simulations of the molecules lack a hands-on aspect. Here a new tool is described that combines the squeezing of a syringe with a computer simulation, and it is shown that this has worked well in class for both…

Today's biology teachers are confronted with many challenges as they endeavour to maintain or improve the quality of their courses. Increasing enrollments, decreasing budgets, environmental considerations, student concerns, and curriculum changes often necessitate change. Providing a quality laboratory experience under such constraints is…

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…

For many, the dominant model of curriculum development in science includes generating a topic, clarifying science content, identifying activities associated with the topic, and figuring out an assessment. Unfortunately, this approach tends to overemphasize activities and underemphasize mastery of science concepts and the process of scientific…

The study explored the relationship of self-concept and locus of control to science engagement and science achievement. Furthermore, the relationship of self variables with science engagement and science achievement was studied across ethnicity, gender, and socioeconomic status (SES). The data were accessed from the 3 waves of the National…

This study aims at highlighting the collaborative activity of two high school students (age 14) in the cases of modeling the complex biological process of plant growth with two different tools: the "paper & pencil" concept mapping technique and the computer-supported educational environment "ModelsCreator". Students' shared activity in both cases…

This article discusses the relationship between procedural and conceptual problem solving in a computer-supported collaborative learning (CSCL) environment designed within the field of science education. The contribution of this article, and our understanding of this phenomenon, is anchored in our socio-cultural interpretation, and that implies…

While increased academic requirements for high school graduation have long been advocated, current research shows a mixed record in mathematics and science achievement among American middle and high school students relative to some of their international peers. In response to these concerns and other calls for reform, states have increased the…

High Schools That Work (HSTW) Assessment data show the need to improve science education in both the middle grades and high school. Science education increases students' critical thinking and problem-solving skills. This publication is designed to help principals, other school leaders and teachers identify rigorous instruction and successfully…

Federal legislation requires that supplementary aids and services be provided to students with diagnosed disabilities to assist them in accessing the general-education curriculum. Such modifications to the curriculum may include assistive technology (AT) devices and services. AT can be any item, piece of equipment, or teacher-made product that is…

"Hands-on" activities play an important, but controversial, role in early science education. In this study we attempt to clarify some of the issues surrounding the controversy by calling attention to distinctions between: (a) type of instruction (direct or discovery); (b) type of knowledge to be acquired (domain-general or domain-specific); and…

This article describes 6 aids for science instruction, including (1) the use of fudge to represent lava; (2) the "Living by Chemistry" program, designed to make high school chemistry more accessible to a diverse pool of students without sacrificing content; (3) NOAA and NSTA's online coral reef teaching tool, a new web-based "science toolbox" for…

Cognetics provides an exciting cooperative learning experience for students that develops both thinking skills and content knowledge. In Cognetics, teams of students in grades 3 to 12 create solutions to problems. This set contains a student manual and a teacher's manual. The teacher's manual explains the concept of cognetics and then provides…

Recent surveys on writing in secondary school science classes indicate that a variety of modes of writing are incorporated for different purposes. The critical essay, the research report, and term paper assignments still demonstrate their usefulness as promoters of learning science. The study guide, another standard teaching tool, also continues…
