Researchers frequently use machine-learning methods in many fields. In the area of detecting fraud in testing, there have been relatively few studies that have used these methods to identify potential testing fraud. In this study, a technical review of a recently developed state-of-the-art algorithm, Extreme Gradient Boosting (XGBoost), is…

Change is the sine qua non of emotion regulation (ER) and, thus, to understand ER we must analyze its temporal dynamics. Articles in the ER section of this special issue provide strong empirical evidence for the centrality of temporal dynamics in the development of ER on 3 levels: Rapid changes in spatial and temporal dynamics across multimodal…

When incorporating the environment into mental processing (cf., "cognitive offloading"), one creates novel cognitive strategies that have the potential to improve task performance. Improved performance can, for example, mean faster problem solving, more accurate solutions, or even higher grades at university. Although cognitive…

How do we assess what we remember? Previous work on metacognition suggests that confidence judgments are more accurate when given after than before a response to a perceptual task. Here we present two experiments that investigate the influence of decision and response on metacognitive accuracy in a memory task so as to establish what kind of…

At the early stages of concept acquisition, physical properties are inseparable of the concepts they form. With development, the concept seems to depart from the physical entities from which it emerged and seems to exist beyond its physical attributes. Numerosity is an abstract concept; however, physical properties such as diameter, area, and…

The testing effect occurs when students, given information to learn and then practice during a test, perform better on a subsequent content post-test than students who restudy the information as a substitute for the practice test. The effect is often weaker or reversed if immediate rather than delayed post-tests are used. The weakening may be due…

Purpose: Frequency lowering in hearing aids can cause listeners to perceive [s] as [?]. The S-SH Confusion Test, which consists of 66 minimal word pairs spoken by 6 female talkers, was designed to help clinicians and researchers document these negative side effects. This study's purpose was to use this new test to evaluate the hypothesis that…

This Data Point uses data from the Adult Training and Education Survey (ATES), administered as part of the 2016 National Household Education Surveys Program (NHES:2016), to examine the relationship between educational attainment and various measures of labor underutilization (defined below). ATES:2016 collected information from a nationally…

Benefiting from item preknowledge (e.g., McLeod, Lewis, & Thissen, 2003) is a major type of fraudulent behavior during educational assessments. This paper suggests a new statistic that can be used for detecting the examinees who may have benefitted from item preknowledge using their response times. The statistic quantifies the difference in…

Writing a thesis is often the culminating experience for undergraduate students enrolled in university honors programs in the United States. Because writing a thesis is one of the most difficult academic tasks that an undergraduate student may undertake, it requires a high level of self-efficacy, or belief in one's capabilities to achieve certain…

Differentiated instruction is a proactive teaching model and philosophy with demonstrated potential to cater for diverse learners and create inclusive classrooms. There is little research, however, into the implementation of this approach in the senior secondary classroom. Teachers' implementation of differentiated instruction has been shown to be…

Student motivation varies quickly, particularly under the pressing context. However, extant literature tends to focus on the individual, rather than contextual, differences in motivational patterns. We examined Korean adolescents' time-varying pursuits of achievement goals and learning outcomes using the experience sampling method, which collects…

Implementing a randomized controlled trial design, the present study investigated the effects of two types of accommodations, linguistic modification and a glossary, for English learners (ELs) taking a computer-based mathematics assessment. Process data including response time and clicks on glossary words were also examined to better interpret…

Objective: Students' enrollment intensity during their first academic semester and year are highly influential in their success and decisions to persist in community college. Limited research, however, has focused on understanding how students navigate the decision-making process of determining their credit load or how institutional support…

There is some evidence that people from lower socio-economic groups (SEGs) are more likely to be either inactive or less active than those from higher SEGs. Currently, there is little evidence to indicate whether this trend is the same for the student population. This study aims to provide this insight to understand the habits and behaviours of…
