Nanoparticles are an increasingly important tool in chemistry research, but currently there are few opportunities for chemistry students to work with nanoparticles in undergraduate analytical courses. In this exercise, designed for an analytical or instrumental analysis lab course, students have the opportunity to work with solutions of silver…

It has been suggested that attenuated adaptation to visual stimuli in autism is the result of atypical perceptual priors (e.g., Pellicano and Burr in "Trends Cogn Sci" 16(10):504-510, 2012. doi:10.1016/j.tics.2012.08.009). This study investigated adaptation to color in autistic adults, measuring both strength of afterimage and the…

This article posits that the comic medium, wedded with traditional essay assignments, may be a powerful tool for social studies teachers, those who prepare social studies teachers at the collegiate level and other teachers and professors who desire to teach about citizenship in an era of "fake news" and alternative facts.

The identification of coloring substances is a relevant task in the field of conservation and restoration, but it can be challenging as in real samples the target analytes are inserted in a very complex matrix made of binders and additives. Understanding this concept is fundamental for upper-division undergraduate students interested in…

Student feedback from an undergraduate biochemistry lab course suggested the use of visibly traceable proteins may assist learning. Based on this feedback, we used guided inquiry lab exercises where students developed and characterized a suite of fluorescent protein-dihydrofolate reductase (DHFR) fusions as tools for a biochemistry teaching lab.…

Every substance is associated to emission of electromagnetic radiation whose peaks are essentially influenced by temperature. Hot bodies (i.e., at T >700 °C) emit electromagnetic radiation in the field of visible light (incandescent light). The radiation emitted by cold bodies (i.e., at normal ambient conditions) in the visible light range is…

How does a picture teach a viewer to look at it, understand it, and make meaning? (The theoretical basis of this article and elements of its expression have been drawn from Peter Pericles Trifonas. (1998). "Cross-mediality and narrative textual form: A semiotic snalysis of the lexical and visual signs and codes of the picture bnook."…

For the first time, this study investigated whether children with autism spectrum disorder (ASD) and typically developing (TD) children matched on language comprehension (M age equivalent = ~ 44 months) are more likely to retain words when learning from colour photographs than black-and-white cartoons. Participants used mutual exclusivity to fast…

People often misrecognize objects that are similar to those they have previously encountered. These mnemonic discrimination errors are attributed to shared memory representations (gist) typically characterized in terms of meaning. In two experiments, we investigated multiple semantic and perceptual relations that may contribute: at the concept…

Everyday task sequences, such as cooking, contain overarching goals (completing the meal), subgoals (prepare vegetables), and motor actions (chopping). Such tasks generally are considered hierarchical because superordinate levels (e.g., goals) affect performance at subordinate levels (e.g., subgoals and motor actions). However, there is debate as…

In this paper, I aim to explore what role persuasion plays in the early education of children. Advocating Wittgenstein, I claim that persuasion involves imparting to a pupil about a particular world-picture ("Weltbild") by showing rather than explaining. This because we cannot introduce a child to the hinges of a world-picture through a…

As the population of the United States becomes more diverse the ethnic makeup of postsecondary institutions expands. Women of color (WOC) represent a growing number within the academic community earning more postsecondary degrees then men and serve as leaders in higher education throughout the county. The increased presence of WOC in academic…

The purpose of the present study was to clarify comprehensively how and to what extent inhibition, spatial working memory (WM), and auditory WM influence agility, balance, and dexterity of motor coordination and comprehensive physical ability in kindergarteners. Participants were 43 children between the ages of 4 and 5 years old. The children…

This study investigates the effects of Processing Instruction (PI) on the acquisition of grammatical gender and gender-marked pronouns in German. PI was compared to Traditional Instruction, i.e. a traditional, vocabulary-oriented approach using color cues (TI) and a Categorization and Memorization task (CM). The results of an immediate posttest…

This article uses reflective drawing to explore representations of multilingualism by Anglophone migrants in Luxembourg. Analysing twelve interviews in which participants drew and described their language experiences, we examine the language ideologies Anglophone migrants adopt in response to the ideologies of English they encounter. Participants…
