Chan, Louis K. H.; Chan, Winnie W. L. – Cognitive Research: Principles and Implications, 2022
From infrared body temperature surveillance to lifeguarding, real-life visual search is usually continuous and comes with rare targets. Previous research has examined realistic search tasks involving separate slides (such as baggage screening and radiography), but search tasks that require continuous monitoring have generally received less…

Ramos, Cristiana V.; Samelo, Jaime; Martins, Patri´cia A. T.; Moreno, Maria João – Journal of Chemical Education, 2022
The amount of protein in complex matrices such as food products is an important characteristic, at both a nutritional and a pedagogical level. There are several methods available for protein quantification, from simple UV absorption to mass spectrometry. The most common are based on the interaction of the proteins with colored compounds followed…

Zhu, Pengfei; Ling, Yizhou – Journal of Chemical Education, 2022
Conventional mobile phone colorimetry usually utilizes the RGB color mode to measure concentration of solutions, but the paper entitled "Determining the Amount of Copper(II) Ions in a Solution Using a Smartphone" proposes the use of hue ("H") to measure the concentration. It is pointed out that the "H" value increases…

Winum, Jean-Yves; Bernaud, Laurent; Filhol, Jean-Se´bastien – Journal of Chemical Education, 2021
Syntheses of analogues of historical indigo and Maya blue pigments using an inquiry-based approach are presented. Derivatives of indigo were synthesized (in particular Tyrian purple) and used as vat dyes for dyeing cotton or wool fabrics or mixed with a sepiolite clay to create new hues or colors of Maya blues using a green chemistry hydrothermal…

Filgueiras, Matheus Fernandes; Borges, Endler Marcel – Journal of Chemical Education, 2022
Students quantified the protein content in beer, milk, powdered milk, and whey protein using the Bradford assay. The assay was carried out using absorbance measured at 595 nm (standard method) and 96-well-plate images (proposed method). They built analytical curves using bovine serum albumin (BSA) and casein and determined that protein type…

Skelton, Alice E.; Maule, John; Franklin, Anna – Child Development Perspectives, 2022
A remarkable amount of perceptual development occurs in the first year after birth. In this article, we spotlight the case of color perception. We outline how within just 6 months, infants go from very limited detection of color as newborns to a more sophisticated perception of color that enables them to make sense of objects and the world around…

Ferrarello, Daniela; Gionfriddo, Mario; Grasso, Federico; Mammana, Maria Flavia – ZDM: Mathematics Education, 2022
The objective of this work is to show an educational path for combinatorics and graph theory that has the aim, on one hand, of helping students understand some discrete mathematics properties, and on the other, of developing modelling skills through a robust understanding. In particular, for the path proposed to middle-school students, we used a…

Werchan, Denise M.; Amso, Dima – Developmental Science, 2021
Previous work has shown that infants as young as 8 months of age can use certain features of the environment, such as the shape or color of visual stimuli, as cues to organize simple inputs into hierarchical rule structures, a robust form of reinforcement learning that supports generalization of prior learning to new contexts. However, especially…

Stephens, Pamela; Fürst, Andrea; Walkup, Nancy – Art Education, 2021
Friedensreich Hundertwasser (1928-2000), an artist with different ideas of architecture, envisioned colorful buildings that incorporate organic shapes and forms, irregular patterns, uneven surfaces, and forests that grow from windows and rooftops. As early as the mid-20th century, Hundertwasser dealt with architecture in ways that offered…

Dahl, Kimberly L.; Stepp, Cara E. – Journal of Speech, Language, and Hearing Research, 2021
Purpose: The purpose of this study was to determine the effect of cognitive load on relative fundamental frequency (RFF) in individuals with healthy voices. Method: Twenty adults with healthy voices read sentences under different cognitive load conditions. Each sentence contained color terms printed in colored ink, creating an embedded Stroop…

Jaconiano, Yasmim R.; Goulart, Juliana S.; Barros, José C.; Michel, Ricardo C. – Journal of Food Science Education, 2021
It began in 1869, and today we have 118 elements listed in the Periodic table, thanks to Mendeleev's work. Carbon, hydrogen, oxygen, and nitrogen are elements presented in many organic compounds. Some of them can exhibit photophysical and photochemical properties. Herein, we proposed an easy to make an experiment in chemistry classes to connect…

Cortel, Adolf – Physics Teacher, 2021
Chladni patterns are one of the most fascinating physics demonstrations. They can be produced very easily using commercially available apparatus based on metallic plates attached to a mechanical driver, similar to a loudspeaker without the membrane, and a signal generator. The figures are observed using sand sprinkled on the surface of the plate.…

Skulmowski, Alexander – Education and Information Technologies, 2022
Digital learning increasingly makes use of realistic visualizations, although realism can be demanding for learners. Color coding is a popular way of helping learners understand visualizations and has been found to aid in learning with detailed visualizations. However, previous research has shown that color coding must not always be an effective…

Martinez, Miriam; Harmon, Janis; Hillburn-Arnold, Margaret; Wilburn, Marcy – Journal of Children's Literature, 2020
Children's literature scholars have written about the importance of color in the visual texts of picturebooks: Color can establish mood, provide clues to the emotional states of characters, highlight particular objects in illustrations, and signal links between characters and/or objects (e.g., Lewis, 2001; Moebius, 1986; Nodelman, 1988). However,…

Zavaruieva, Inna; Bondarenko, Larysa; Fedko, Olha – Review of Education, 2022
The paper considers the practical experience of creating educational visual materials on the Ukrainian language as a foreign language using innovative technologies, namely, the specifics of the role and place of colour and colour symbols as a code sign during the assimilation of new educational information. This study employed the following…
