It was obvious long ago that for mechanical behavior a gravitational field and an accelerating frame of reference are equivalent. Or in other words: it is impossible to decide whether you are in an accelerating elevator or in a closed room on a planet with a different value of "g". In the first section of this article I will describe a simple…

Understanding the role of "representations" in cognitive science is a fundamental problem facing the emerging framework of embodied, situated, dynamical cognition. To make progress, I follow the approach proposed by an influential representational skeptic, Randall Beer: building artificial agents capable of minimally cognitive behaviors and…

The metamemory approach to memory confidence was extended and elaborated to deal with semantic memory tasks. The metamemory approach assumes that memory confidence is based on the products and processes of a completed memory task, as well as metamemory beliefs that individuals have about how their memory products and processes relate to memory…

Tomlinson's explanation of Artful Teaching and her 2017 expansion of this concept The Five Key Elements of Differentiation provide the theoretical framework of this examination of the need for science investigations in elementary schools. The Artful Teaching framework uses an equilateral triangle with vertices labeled The Teacher, The Student, and…

To improve the student learning outcomes of an introductory Human Anatomy and Physiology course we have implemented many changes over the last two years. In this study, the third of a three-part series, we present data from surveys collected and analyzed during the spring semester of 2018 at the University of Northern Colorado. The results reveal…

Research-based learning motivates students to identify with different subjects. The orientation program MINTgrün at Technische Universität Berlin offers two study semesters for open choices of teaching modules, including a series of specially designed laboratories covering topics like robotics, construction, environmental research, programming,…

The current empirical study examines relationships between network measures and learning performance from a social network analysis perspective. We collected computerized, networking data to analyze how 401 junior high students connected to classroom peers using text- and video-based material on iPads. Following a period of computerized…

At many higher education institutions, admissions decisions often rely on standardized test scores and high school grades; yet, they are less reliable predictors for applicants falling slightly below cutoff points, what we call borderline applicants. Since borderline applicants are often from underrepresented backgrounds and diverted to 2-year…

The urgency of the given problem is caused by the necessity to develop an innovative education system capable of producing highly qualified specialists with a wide range of social and professional activities and broad-based abilities ready for individual operating innovative activities. The article is intended to searching for the ways of…

In this work, an educational experience is described in which a microwave communication link is used to make students aware that all electromagnetic waves have the same physical nature and properties. Experimental demonstrations are linked to theoretical concepts to increase comprehension of the physical principles underlying electromagnetic…

The extraction and analysis of fats from convenience foods (crackers, cookies, chips, candies) has been developed as an experiment for a second-year undergraduate organic chemistry laboratory course. Students gravimetrically determine the fat content per serving and then perform a [superscript 1]H NMR analysis of the recovered fat to determine the…

There is growing interest in the use of low enthalpy geothermal (LEG) energy schemes, whereby heated water is extracted from sandstone aquifers for civic heating projects. While prevalent in countries with volcanic activity, a recently proposed scheme for Manchester offered the perfect opportunity to engage students in the viability of this form…

A Web site is described that facilitates use of the free computational chemistry software: General Atomic and Molecular Electronic Structure System (GAMESS). Its goal is to provide an opportunity for undergraduate students to perform computational chemistry experiments without the need to purchase expensive software.

William Henry Bragg moved from Cambridge in Britain to South Australia to take up a professorship at the University of Adelaide in 1885. He brought with him a broad interest in many areas of physics, but when Wilhelm Roentgen discovered X-rays in the 1890s, Bragg's interest was stimulated. William's Australian-born son, Lawrence (WL Bragg), began…

People consider alternative causes when deciding whether a cause is responsible for an effect (diagnostic inference) but appear to neglect them when deciding whether an effect will occur (predictive inference). Five experiments were conducted to test a 2-part explanation of this phenomenon: namely, (a) that people interpret standard predictive…
