This study investigated the influence of two contextual factors, parental involvement and perceived career barriers, on math/science goals. Using social cognitive career theory (SCCT; Lent, Brown, & Hackett, 1994), a path model was tested to investigate hypothesized relationships between math- and science-related efficacy beliefs (i.e., task and…

The case-based computerized laboratory (CCL) is a chemistry learning environment that integrates computerized experiments with emphasis on scientific inquiry and comprehension of case studies. The research objective was to investigate chemical understanding and graphing skills of high school honors students via bidirectional visual and textual…

Members of a team of educators and university students participating in the project, Pittsburgh Partnership for Energizing Science in Urban Schools, addressed the issue of helping students develop investigative skills within the context of an introductory science unit for fourth graders. The unit focuses on data-collection techniques and is a…

This paper reports on a quasi-experimental study which examined the effectiveness of concept mapping as a revision tool in enhancing pupils' examination performances in primary science. The research objective seeks to determine whether there are significant differences in achievement between the concept mapping and traditional method of revision…

This article presents a learning cycle with the aim of helping students understand the evidentiary basis of scientific claims. Students consider data and interpretations as used to support contradictory views in the debate surrounding the causal relationship between human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS).…

Making connections is an emerging education theme of the 21st century. Science teachers are encouraged to connect new learning with prior knowledge, learning with student interests and experience, and classroom activities with the history and nature of science. Strategies that facilitate these connections enrich and enhance instruction. In this…

"How much popcorn will our classroom hold?" This intriguing question sparked a terrific integrated science and math exploration that the author conducted with fifth-and sixth-grade students. In the process of finding the classroom's volume, students developed science-process skills (e.g., developing a plan, measurement, collecting and interpreting…

A video-based program on lesson analysis for pre-service mathematics teachers was implemented for two consecutive years as part of a teacher education program at the University of Lazio, Italy. Two questions were addressed: What can preservice teachers learn from the analysis of videotaped lessons? How can preservice teachers' analysis ability,…

This paper reports on a small scale study undertaken at the University of Iowa to examine whether students perceive a difference as to the value of learning in General Education Requirement (GER) science classes compared to learning in science application courses. It also explores the need for a different approach to the teaching of science…

'Scientific Investigation' was the first of the four Attainment Targets which prescribed the science component of the national curriculum in England and Wales in 1991. Following a brief historical account of the origins of scientific investigation as a curriculum objective, this paper comments upon the attempt by the central government to define a…

This book is organized around a set of simple observational physics activities that stimulate questioning and answering and encourage the generation of answers to stimulate individual creativity. The activities integrate drawing, counting, measuring, predicting, recording, hypothesizing, and verifying. The activities are designed to sharpen…

Science educators and other are faced with determining what changes must be made in education to insure scientific literacy for all students. One area that has been identified as playing a crucial role in science achievement outcome is assessment. This monograph focuses on improving assessment techniques used by teachers as they devise tests to…

The question addressed here is how to integrate computational tools, namely interactive general-purpose platforms, in the teaching of process units. Mathematica has been selected as a complementary tool to teach distillation processes, with the main objective of leading students to achieve a better understanding of the physical phenomena involved…

An established methodology involving the sequential presentation of five skills on ASPEN Plus to undergraduate seniors majoring in ChE is presented in this document: (1) specifying unit operations; (2) manipulating physical properties; (3) accessing variables; (4) specifying nonstandard components; and (5) applying advanced features. This…

This report provides guidance for a rigorous science curriculum in the middle grades based on a solid set of essential standards that can prepare all students to perform at least at the basic level of proficiency and for increasing percentages of students to perform at the proficient and advanced levels. This report is organized around 19…
