We describe and evaluate a method to mitigate unwanted student collaborations in assessments, which we recently implemented in a second-year undergraduate mathematics module. The method requires a list of specific pairs of students to be prevented from collaborating, which we constructed based on the results of previous assessments. We converted…

Can metaphorical reasoning involving embodied experience--such as color perception--be learned from the statistics of language alone? Recent work finds that colorblind individuals robustly understand and reason abstractly about color, implying that color associations in everyday language might contribute to the metaphorical understanding of color.…

Negation is usually considered as a linguistic operator reversing the truth value of a proposition. However, there are various ways to express negation in a multimodal manner. It still remains an unresolved issue whether nonverbal expressions of negation can influence linguistic negation comprehension. Based on extensive evidence demonstrating…

Colors in the learning environment are likely to affect students' memory. In addition, each individual's interest and attitude towards colors change over time under the influence of different factors. Thus, this very question arises "what is the relationship between color preferences and effects of colors on memory on students' learning in…

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…

Purpose: The current project aimed to examine the effects of two experimental cognitive-linguistic paradigms, the Stroop task and a primed Stroop task, on speech kinematics and perioral muscle activation. Method: Acoustic, kinematic, and surface electromyographic data were collected from the verbal responses of 30 young adult healthy control…

Classroom lighting, when set to high luminous (lx) and cooler correlated color temperature (CCT) conditions, can increase student focus, concentration, and oral reading fluency (Mott et al., 2012; 2014). However, when illuminance is too high and color temperature is too cool, irritating and adverse effects can occur such as visual fatigue and…

Children (N = 103, 4-9 years, 59 females, 84% White, c. 2019) completed visual processing, visual feature integration (color, luminance, motion), and visual search tasks. Contrast sensitivity and feature search improved with age similarly for luminance and color-defined targets. Incidental feature integration improved more with age for…

Quinacridone red and violet are visually different colors, an observation confirmed by their visible reflectance spectra and CIE L*a*b* coordinates. However, their IR spectra are extremely similar. Though chemically identical, the two quinacridones are polymorphs. In this experiment, designed for and tested by nonscience majors, the pigments are…

Photochemical reactions are the reactions that are induced by light. Many of these reactions are found in natural processes, including photosynthesis and the formation and decomposition of ozone in the atmosphere. Classroom demonstrations are effective in enhancing students' learning and retention. Herein, we have developed a simple demonstration…

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…

A simple demonstration adaptable to classroom conditions is presented, which involves the preparation of raffle tickets using filter paper and the solution of selected fluorophores. With an appropriate dilution, the text written on the tickets is not visible to the naked eye; however, it becomes readable once put under a UV lamp. Besides being a…

Repeating a single-prime stimulus as a target to respond to usually facilitates responses. However, sometimes, prime repetition slows the responses and produces the single-prime negative priming effect. In this study, the distractor set hypothesis was proposed as a mechanism of attentional control that can contribute toward single-prime negative…

Practical experiments enhance students' understanding of basic concepts and promote deep learning experiences in chemistry. The smartphone application of Lab4Chemistry was utilized to replace colorimeters with smartphone camera sensors. Low-cost and readily available materials, including anthocyanin (fresh red cabbage) and common kitchen…

The following activity was developed to allow students to actively participate in and measure the kinetics of a multistep process. Each group of students is given a stack of blank coloring pages, each with a rainbow design printed on it. Each student in a group is given a different color crayon and colors in their portion of the picture before…
