The assessment of ecological factors that affect individual mental health or academic functioning is an important component of educational and psychological consultation. Researchers and practitioners have conceptualized such ecological or environmental factors in a variety of ways and from a broad range of perspectives. In this article we…

One challenge for music educators is to find techniques to help students "listen across time" to the examples they are assigned to study and to stay focused on a piece as they listen. Measurement tools to assess music listening have a long history, ranging from very simple to very complex, and very dated to very recent. This article traces the…

This dissertation studies clouds over the polar regions using the Multi-angle Imaging SpectroRadiometer (MISR) on-board EOS-Terra. Historically, low thin clouds have been problematic for satellite detection, because these clouds have similar brightness and temperature properties to the surface they overlay. However, the oblique angles of MISR…

Purpose: The purpose of this paper is to investigate the role of instruments defined as artefacts, rules, models or norms, in the articulation between knowing-in-practice and knowledge, in learning processes. Design/methodology/approach: The paper focuses on a distributed, knowledge-intensive and instrumented activity at the core of any collective…

These days, multiplying two numbers together is a breeze. One just enters the two numbers into one's calculator, press a button, and there is the answer! It never used to be this easy. Generations of students struggled with tables of logarithms, and thought it was a miracle when the slide rule first appeared. In this article, the author discusses…

A simulation game is used to teach students in instrumental analysis courses to find the latest developments in the field, use the journal literature, and apply critical thinking to determine the relative importance of the work they find. They also learn about the business of chemical instruments and to make oral presentations. The competitive…

This article details the construction and use of the 555-timer checker. The 555-timer checker allows the user to dynamically check a 555-timer, an integrated circuit device. Of its many applications, it provides timing applications that unijunction transistors once performed. (Contains 4 figures and 3 photos.)

Accusport analyzers were used to generate lactate performance curves in an investigative laboratory activity emphasizing the importance of reliable instrumentation. Both the calibration and testing phases of the exercise provided students with a hands-on opportunity to use laboratory-grade instrumentation while allowing for meaningful connections…

In the field of automation technology, research and development for industrial applications has increased rapidly in recent years. Therefore, industrial automation and control education is a very important element of the industrialization process in developing countries, such as Turkey, which needs to keep abreast for the latest developments in…

Early math skills are the strongest predictors of later math achievement in school. This two-wave study addressed three research questions about the role of families in fostering these skills in preschool-aged children. First, how do families talk about math at home? Second, how do these conversations vary across families with different…

A linearization method of the nonlinear differential equation for conservative nonlinear oscillators is analysed and discussed. This scheme is based on the Chebyshev series expansion of the restoring force which allows us to obtain a frequency-amplitude relation which is valid not only for small but also for large amplitudes and, sometimes, for…

The plumbing products most appropriate for a high-end hotel or executive restroom will differ from those most suited for school and university restrooms, where large numbers of boisterous students may charge through the doors all day long. However, installing plumbing that can stand up to rough-and-tough student use does not have to compromise…

A novel wireless communications systems laboratory course is introduced. The course teaches students how to design, test, and simulate wireless systems using modern instrumentation and computer-aided design (CAD) software. One of the objectives of the course is to help students understand the theoretical concepts behind wireless communication…

The drooping mercury electrode (DME) was previously used to carry out electrochemical experiments but invention of polarography technique changed this. Voltammetry with DME was given the term polarography and are used in measurement of current as a function of potential at small electrodes.

Princeton Applied Research Corporation (PAR) was a small electronic instrument company in early 1960s but once they entered electrochemistry they were very successful. Since then they have developed and designed successful instruments with their tremendous knowledge and have made great contribution to the field of analytical chemistry.
