This paper describes an in-class activity to introduce random assignment, paired data, and learning effect. The activity requires minimal materials, can be completed in a single class period, and is suitable for those using technology to conduct data exploration but can also be adapted for use in a technology-free classroom. The activity consists…

Joint attention (JA) has been found to correlate with many developmental outcomes. However, little is known about how naturalistic JA is established and develops during early infancy. In this study, free-flowing tabletop toy play between infants at 5 and 15 months and their mothers (N = 48 dyads; 65% white) was observed to (1) examine changes in…

This article aims to provide a comparative study between theater and performance art, focusing on a particular approach to design and execution in theater. In this approach, everything happens collaboratively, and instead of individual directing and playwriting, design and execution are carried out as a group effort, with the author primarily…

For institutions intent on improving their research student outcomes, it is important to identify the variables most strongly associated with timely or tardy completions, which the university has the potential to influence or amend. For this to occur the analyses of doctoral completion times need to be conducted at an institution or discipline…

This research presents the findings of an 8-month ethnographic case study of one infant/toddler classroom in the southeastern United States. Participants included the classroom's two (white, female) teachers and a racially diverse group of 12 children between one to 2 years of age. Grounded within an ethics of care theoretical framework, this…

Modifications are presented for the iodine clock reaction to introduce the concept of activity and to help students better appreciate molecular aspects of chemical equilibrium. The addition of an unreactive salt affects the activity of the reactants in the iodine clock reaction. The difference in activity affects how long the iodine clock reaction…

Since the Middle Ages, Augustine and the wealth of his writings have had an enormous impact on Western philosophical thinking. His approach to time and memory, which he sets out in his eleventh book of the "Confessions," is one of the most important sources for research about the philosophy of time. Augustine describes time as a…

Curiosity can be a powerful motivator to learn and retain new information. Evidence shows that high states of curiosity elicited by a specific source (i.e., a trivia question) can promote memory for incidental stimuli (non-target) presented close in time. The spreading effect of curiosity states on memory for other information has potential for…

This collective writing piece takes its points of departure from the chronotope - a spatio-temporal matrix that constitutes current cultural experiences, which are subjected to dialogic philosophical analysis. Doing so renders unconscious or abstract elements as 'profoundly spatial and concrete' (Bakhtin, 1981, p. 208, emphasis in original),…

Several states in the US have removed time limits on their state assessments. In Indiana, where this study takes place, the state assessment is both untimed during the testing window and allows unlimited breaks during the testing session. Using grade 3 and 8 math and English state assessment data, in this paper we focus on time used for testing…

The science, technology, engineering, and mathematics (STEM) sciences play a pivotal role in developing nations, both in terms of developing newer and better solutions to problems and also in the approach used to solve those problems. An excellent predictor of future success in the STEM sciences is the ability to mentally manipulate shapes, also…

The prevailing hypothesis for observed post-rest motor reaction time improvements is offline consolidation. In the present study, we present evidence for an alternate account involving the accrual and dissipation of reactive inhibition. Four groups of participants (N = 159) performed a finger-tapping task involving either massed (30 s per trial)…

Community colleges were established as affordable postsecondary education opportunities for all residents within their local areas. Typical measures of access to postsecondary institutions use binary indicators based on the presence of institutions within geographic areas or straight-line distance between student residences and college locations…

Between the Fall of 2016 through February of 2022 (the start of the pandemic) the author drove as an independent contractor for both Uber and Lyft--the ridesharing companies. During this time, he provided 4,590 rides (with a 4.97- star rating) in Boston, MA and the neighboring communities. When he decided to drive for these rideshare platforms, he…

Natural environments provide a rich spatiotemporal context that allows for visual objects to be differentiated based on different types of information: their absolute or relative spatial or temporal coordinates, or their ordinal positions in a spatial or temporal sequence. Here, we investigated which spatial and temporal properties are…
