Some simple modeling with Riemann sums can be used to develop Beer's Law, which describes the relationship between the absorbance of light and the concentration of the solution which the light is penetrating. A further application of the usefulness of Beer's Law in creating calibration curves is also presented. (Contains 3 figures.)

The uniform precession of a simple form of gyroscope is analysed via a direct application of Newton's laws, using only concepts generally taught to physics and engineering students in the first two years of an undergraduate programme, with an emphasis on understanding the forces and torques acting on the system. This type of approach, in the…

The ice cream laboratory experiment is designed to illustrate and promote discussion of several engineering and science topics including material and energy balances, heat transfer, freezing, mass transfer, mixing, viscosity, and freezing point depression in a sophomore level engineering class. A pre-lab assignment requires the students to develop…

This paper is an general article about the influence of constructivism on nature of science. Constructivism has influenced research on the teaching and learning of nature of science, as well as actual teaching of the nature of science ideas. In the area of research, a constructivist learning theory perspective has influenced researchers to shift…

The past two decades have seen an increased need for better consumer reporting in education. This has resulted in part from a variety of education initiatives sponsored by the US Department of Education (ED) and others. The initiatives have increased the number of school improvement options available to educators and encouraged--or sometimes…

This article explores the meaning of the nature of science education to enhance scientific literacy. It argues that the teaching approach for science education should be regarded as "education through science", rather than "science through education". A model of the nature of science education is proposed, having its foundations based on activity…

Problem statement: In the context of science education reform in Thailand, we need to prepare science teachers who can face science and social issues controversial; teachers can response the question socioscientific issues and let their students to meet the goal of science education. This study investigated the conception leading preservice…

Constructing scientific explanations and participating in argumentative discourse are seen as essential practices of scientific inquiry (e.g., R. Driver, P. Newton, & J. Osborne, 2000). In this paper, we identify three goals of engaging in these related scientific practices: (1) sensemaking, (2) articulating, and (3) persuading. We propose using…

This paper presents staff perceptions of higher education science and engineering learning communities derived from a cross-case analysis of four case studies across the New Zealand university and polytechnic sectors. First we report staff expectations and experiences in terms of infrastructure and resources, and their own careers. Staff…

One hundred years after its conception, the scientific method continues to reinforce a kind of cultural lore about what it means to participate in inquiry. As commonly implemented in venues ranging from middle school classrooms to undergraduate laboratories, it emphasizes the testing of predictions rather than ideas, focuses learners on material…

I begin by examining the natures of science and religion before looking at the ways in which they relate to one another. I then look at a number of case studies that centre on the relationships between science and religion, including attempts to find mechanisms for divine action in quantum theory and chaos theory, creationism, genetic engineering…

The No Child Left Behind Act of 2001 (NCLB) specifies that all educational programs or curricula be supported by "scientifically based research" in order to ensure better quality control. However, in the arena of sex education, the federal government allocates millions of dollars in grants for schools and organizations to implement…

A sixth-grade class investigated the ecologies of two local retention ponds over the course of one school year. In this context, instruction assisted development as students designed models of the pond in one-gallon jars and attempted to stabilize these jars in sustainable ecosystems that could be used to study questions about the ponds.…

In this paper I ask whether the University has a special role to play in democratic societies. I argue that the modern University can no longer lay claim to a research monopoly since nowadays research is conducted in many places outside of the University. The University can, however, still lay claim to a kind of knowledge monopoly which has to…

Models are often used when teaching science. In this paper historical models and students' ideas about genetics are compared. The historical development of the scientific idea of the gene and its function is described and categorized into five historical models of gene function. Differences and similarities between these historical models are made…
