The gasometric analysis of nitrogen produced in a reaction between sodium nitrite, NaNO[superscript 2], and sulfamic acid, H(NH[superscript 2])SO[superscript 3], provides an alternative to more common general chemistry experiments used to study the ideal gas law, such as the experiment in which magnesium is reacted with hydrochloric acid. This…

This chapter is a call for consequential education research that has transformative potential: intellectually, educationally, and socially. It is about learning to see differently. It is an argument about seeing our work with youth and communities in ways that can help education researchers see ingenuity instead of ineptness and inability, to see…

Researchers are increasingly interested in working memory (WM) training. However, it is unclear whether it strengthens comprehension in young children who are at risk for learning difficulties. We conducted a modest study of whether the training of verbal WM would improve verbal WM and passage listening comprehension and whether training effects…

Background: This research investigates the impact of a junior secondary astronomy education programme undertaken in four Australian educational jurisdictions. Purpose: Junior secondary students' perceptions of the science they experience at School are examined both before, during and after their engagement with a science programme targeting…

The Anatomy Learning Experiences Questionnaire (ALEQ) was designed by Smith and Mathias to explore students' perceptions and experiences of learning anatomy. In this study, the psychometric properties of a slightly altered 34-item ALEQ (ALEQ-34) were evaluated, and correlations with learning outcomes investigated, by surveying first- and…

The effects of the duration of remember and forget cues were examined to test the differential rehearsal account of item-based directed forgetting. In Experiments 1 and 2, cues were shown for 300, 600, or 900 ms, and a directed forgetting effect (better recognition of remember than forget items) was found at each duration. In addition, recognition…

Simple numerical data analysis is described, using a standard spreadsheet program, to determine distance, velocity (speed) and acceleration from voltage data generated by a skateboard/longboard speedometer (Hare 2012 "Phys. Educ." 47 409-17). This simple analysis is an introduction to data processing including scaling data as well as…

Nowadays, in the United Kingdom, citizens take for granted clean water pumped directly into their homes, but it was not always the case, and is still not so in many countries. Could people clean water themselves if they had to and what could they then use it for? Would it actually be "clean enough" to drink? The author presents children…

Dimensional analysis is often a subject reserved for students of fluid mechanics. However, the principles of scaling and dimensional analysis are applicable to various physical problems, many of which can be introduced early on in a university physics curriculum. Here, we revisit one of the best-known examples from a first course in classic…

In this paper of I have reviewed the test done for validating the special theory of relativity using masers and lasers in last one century. Michelson-Morley did the first experimental verification for the isotropy of space for the propagation of light in 1887. It has an accuracy of 1/100th of a fringe shift. The predicted fringe shift on the basis…

African violet (genus "Saintpaulia") was identified as a particularly suitable genus for the study of specialised plant cells in the classroom using microscopes. The techniques described here involve simple preparation without staining. The cells and structures that can be investigated include: trichomes (hairs); stomata; guard cells and…

The study of electricity and magnetism is fundamental to all first-year physics courses. Developing simple electricity laboratory experiences that are open ended and inquiry based can be difficult. We wished to create a lab experiment where the students have some control over the experimental design, data analysis is required, and students…

Past research has shown that hostile schemas and adverse experiences predict the hostile attributional bias. This research proposes that seemingly nonhostile beliefs (implicit theories about the malleability of personality) may also play a role in shaping it. Study 1 meta-analytically summarized 11 original tests of this hypothesis (N = 1,659),…

A book written in a foreign language and migrated to the US along with its author, an art historian, finds a new communicative dimension by becoming a ready-made for art making purposes. Starting with an introduction explaining the genesis of the collaborative project "Access Denied," this article focuses on one of the series'…

Efforts to provide active research context to introductory courses in basic sciences are likely to better engage learners and provide a framework for relevant concepts. A simple teaching and learning experiment was conducted to use concepts in organic chemistry to solve problems in the life sciences. Bryant University is a liberal arts university…
