A laboratory experiment is described in which students fabricate disk-shaped gold and platinum microelectrodes with diameters of 10-50 [mu]m by sealing sodalime glass with metal microwires. The electrodes are characterized by performing cyclic voltammetry in aqueous and acetonitrile solution. Commercial microelectrodes are expensive (cost depends…

Curtis, Jeremy – School Science Review, 2012
Gravity affects everything we do. Only in very recent years have we been able to carry out experiments in orbit around the Earth and see for the first time how things behave in its absence. This has allowed us to understand fundamental processes better and to design new materials using this knowledge. (Contains 6 figures.)

Australian and New Zealand universities commenced a new academic year in February/March 2020 largely with "business as usual." The subsequent Covid-19 pandemic imposed unexpected disruptions to anatomical educational practice. Rapid change occurred due to government-imposed physical distancing regulations from March 2020 that…

Dopico, Eduardo; Linde, Ana R.; Garcia-Vazquez, Eva – Journal of Biological Education, 2014
Introducing research in undergraduate biology studies may contribute to creating research vocations and generate the idea that science may influence all aspects of common life. However, laboratory practices are too often disconnected from current investigations and rarely address real-life questions that are really interesting for students.…

Information and communication technologies are an effective means of formation of the creative potential of future physics teachers, as with their science-based application in the educational process at the university they allow fully activating learning activities of students, and provide conditions for their creative self-realization in the…

Gomez-Sacristan, Angel; Sempere-Paya, Victor M.; Rodriguez-Hernandez, Miguel A. – IEEE Transactions on Education, 2016
Teaching in university engineering departments is currently facing a number of challenges, especially for those involved in the most innovative and dynamic areas of information and communication technology. Learning model developments that place greater weight on laboratory activities require investment in specific equipment that is often very…

Hendel, Samuel J.; Young, Elizabeth R. – Journal of Chemical Education, 2016
Electrochemical analysis is an important skill to teach in chemistry curricula because it is a critical tool in current high-impact chemical research. Electrochemistry enables researchers to analyze a variety of systems extending from molecules to materials that encompass research themes ranging from clean energy to substrate activation in…

Ryan, Wendy L.; St. Iago-McRae, Ezry – Bioscene: Journal of College Biology Teaching, 2016
Experimentation is the foundation of science and an important process for students to understand and experience. However, it can be difficult to teach some aspects of experimentation within the time and resource constraints of an academic semester. Interactive models can be a useful tool in bridging this gap. This freely accessible simulation…

Grosu, Ioan; Featonby, David – Physics Education, 2016
This driven top is quite a novelty and can, with some trials, be made using the principles outlined here. This new top has many applications in developing both understanding and skills and these are detailed in the article. Depending on reader's available time and motivation they may feel an urge to make one themselves, or simply invest a few…

Childers, Jane B.; Parrish, Rebecca; Olson, Christina V.; Burch, Clare; Fung, Gavin; McIntyre, Kevin P. – Journal of Cognition and Development, 2016
An important problem verb learners must solve is how to extend verbs. Children could use cross-situational information to guide their extensions; however, comparing events is difficult. In 2 studies, researchers tested whether children benefit from initially seeing a pair of similar events ("progressive alignment") while learning new…

DeCaro, Marci S.; Van Stockum, Charles A., Jr.; Wieth, Mareike B. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2016
Higher working memory capacity (WMC) improves performance on a range of cognitive and academic tasks. However, a greater ability to control attention sometimes leads individuals with higher WMC to persist in using complex, attention-demanding approaches that are suboptimal for a given task. We examined whether higher WMC would hinder insight…

Després, Christophe; Jacoboni, Pierre; Py, Dominique; Lekira, Aina – Journal of Interactive Learning Research, 2016
In this paper, we study how to support a human tutor who regulates learners' activities, in a situation of mediated tutoring. Our goal is to provide the tutor with information about the effect of his/her interventions. To achieve this, we adopt an indicator-based approach and define the notion of meta-indicator. The distinguishing feature of…

Usami, Satoshi; Sakamoto, Asami; Naito, Jun; Abe, Yu – International Journal of Testing, 2016
Recent years have shown increased awareness of the importance of personality tests in educational, clinical, and occupational settings, and developing faking-resistant personality tests is a very pragmatic issue for achieving more precise measurement. Inspired by Stark (2002) and Stark, Chernyshenko, and Drasgow (2005), we develop a pairwise…

Balancing Efficiency and Effectiveness for Fusion-Based Search Engines in the "Big Data" Environment
Li, Jieyu; Huang, Chunlan; Wang, Xiuhong; Wu, Shengli – Information Research: An International Electronic Journal, 2016
Introduction: In the big data age, we have to deal with a tremendous amount of information, which can be collected from various types of sources. For information search systems such as Web search engines or online digital libraries, the collection of documents becomes larger and larger. For some queries, an information search system needs to…

Nunn, John – Physics Education, 2016
This paper aims to enable schools to make their own low-cost temperature logging instrument and to learn something about its calibration in the process. This paper describes how a thermistor can be integrated into a simple potential divider circuit which is powered with the sound output of a computer and monitored by the microphone input. The…
