Observe Your Shadow was the title of an observational experiment that was, among others, conducted in the scope of the past year's (2014-2015) first Slovene science competition for elementary school pupils between the ages of 6 and 13. The main reason for establishing a new science competition was popularization of science and its experimental…

This paper reports an undergraduate laboratory experiment to measure heterogeneous liquid/gas reaction kinetics (ozone-oleic acid and ozone-phenothrin) using a flow reactor coupled to an attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectrometer. The experiment is specially designed for an upper-level undergraduate Physical…

A simple experiment is described to measure the coefficient of rolling friction for a low bounce ball rolling on a horizontal surface. As observed previously by others, the coefficient increased with rolling speed. The energy loss due to rolling friction can be explained in terms of the measured coefficient of restitution for the ball, meaning…

In this paper, we discuss some of the ways in which forces of globalisation have transformed the spaces in which educational policies are now developed and practices now enacted. We will consider further the widely held claim that the emergence of these transnational spaces requires new ways of thinking about comparative education. We will examine…

The aims of this research are 1) to explore the inter-relationships within the individual elements or tenets of Nature of Science (NOS), based on the dimensions of scientific knowledge in science learning, and 2) to consider Kuhn's concept of how scientific revolution takes place. This study suggests that instruction according to our NOS Flowchart…

A multi-instrument approach has been applied to the efficient identification of polymers in an upper-division undergraduate instrumental analysis laboratory course. Attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) is used in conjunction with differential scanning calorimetry (DSC) to identify 18 polymer samples and…

The design and fabrication of functional scientific instrumentation allows students to forge a link between commonly reported numbers and physical material properties. Here, a two-point and four-point probe station for measuring electrical properties of solid materials is fabricated via 3D printing utilizing an inexpensive benchtop…

We report here the development of an inexpensive and engaging laboratory-based activity that can help students learn about the scientific method and the role of plant epicuticular waxes and surfactant function on waxy plant leaves as real life example in the agricultural industry. Three each of nontreated collard leaves ("Brassica…

Fostering students' ability to engage in scientific argumentation is an essential component of science teaching.. Unfortunately, research shows that teachers often lack sufficient prior experiences. As teacher educators, we sought to better understand how to effectively provide such critical experiences. Furthermore, we wanted to understand how…

In this article, I explore the tension between the current political context in which science needs defending against anti-intellectualism and outright assaults on evidence as a means of decision-making on the one hand and the overzealous scientism that can result from backlash against a perceived lack of rigor in various forms of inquiry. To do…

Very little research examines the critical intersection between science and special education (SPED), let alone between the nature of science (NOS) and SPED. Thus, this study focused on preservice SPED teachers' conceptions of NOS, their NOS instructional practices, and their perceptions of the influence of course components on their NOS…

The purpose of this study is to determine specific features of investment regulation mechanism aimed at providing effective implementation of projects in the context of industrial-innovative development of Kazakhstan. There the used the system of general scientific and special research methods providing the possibility to disclose processes and…

The distinction between facts and moral values is highly desirable: science and politics should keep to their own territories. Traditionally speaking, science can be seen as an ivory tower, which attempts to do its job in isolation of external influences. Politics does not mandate methods of scientific research or standards of justification;…

The purpose of this study was to find out more effective teaching among problem solving strategy with a scientific approach to students' mathematical abilities in high order thinking skills. This quasi experimental study used non-equivalent pretest-posttest control group design. The experimental group was students who were taught with problem…

Young's double-slit experiment is one of the most historically significant works in physics, and one that is easily done in an introductory physics class. It is also an excellent example of an investigation that allows us to infer the nature of phenomena beyond direct observation. Unfortunately, perhaps because of this, it is often also an…
