Journalists have reported large-scale lead poisoning affecting children in cities such as Flint, Michigan. Unfortunately, children's exposure to lead is not isolated and occurs throughout the country in both urban and rural settings. The effects of lead exposure can cause children to develop disabilities, potentially requiring special education…

Academic department chairs are middle managers in higher education that have unique positions within an institution. This study examined novice department chairs' leadership identity within eastern United States community colleges. Novice was defined as a person having three or fewer years of experience in the department chair position. The gap in…

College students' interactions with campus leaders are a crucial element of their success and satisfaction in higher education; however, little is understood about students' identification, perceptions, or expectations of campus leaders. To help fill this gap in the literature, I led two exploratory studies in collaboration with my committee chair…

Heterocyclic compounds are an integral part of research, particularly in the pharmaceutical field. The synthesis of such compounds in an undergraduate laboratory can help students understand the relevance and importance of their field of study. Our experimental activity introduces a novel procedure to synthesize coumarin, a heterocyclic formed by…

Generation Z, born between 1997 and 2012, has taken over university classrooms. A sample of 592 U.S. Generation Z students enrolled in an agricultural leadership course was examined to determine if talent theme trends exist for the target population and how this information could enhance learning environments and agricultural education. The…

Early identification and intervention are recognised as important elements of the clinical pathway for autism spectrum disorder (ASD). Children with ASD and attention deficit hyperactivity disorder (ADHD) may be diagnosed at a different age than children who only have one of these diagnoses. This systematic review aimed to identify the age at…

This study aimed to describe: the correlation of achievement motivation with student talent, the correlation of self-efficacy with student talent, the correlation of achievement motivation and self-efficacy with students' talents. This study used a quantitative approach with a descriptive method of correlation. While the population of this study…

Nationally, educators suspend Black students at greater rates than any other group. This disproportionality is fueled by stereotypes casting Black students as "troublemakers"--a label students too often internalize as part of their identities. Across two independent double-blind randomized field trials involving over 2,000 seventh…

Previous research has produced mixed results on the question of whether confidence in ad hoc veracity judgments can be used as an indicator of judgment accuracy. These studies have used a variety of measures to analyze the confidence-accuracy relationship; however, they have rarely explicitly addressed why a particular measure was chosen and what…

Research has consistently shown people predominantly rely on undiagnostic nonverbal cues when detecting deceit, whereas verbal cues are more accurate. In three experiments, we investigated whether the simple instruction not to focus on nonverbal cues would make people focus more on diagnostic verbal cues and hence more accurate in detecting lies.…

The rise of online proctoring potentially provides more opportunities for item harvesting and consequent brain dumping and shared "study guides" based on stolen content. This has increased the need for rapid approaches for evaluating and acting on suspicious test responses in every delivery modality. Both hiring proxy test takers and…

With Big Data revolution, the education sector is being reshaped. The current data-driven education system provides many opportunities to utilize the enormous amount of collected data about students' activities and performance for personalized education, adapting teaching methods, and decision making. On the other hand, such benefits come at a…

The approach to identifying evidence for inclusion in realist reviews differs from that used in 'traditional' systematic reviews. Guidance suggests that realist reviews should be inclusive of diverse data from a range of sources, gathered in iterative searching cycles. Saturation is prioritised over exhaustiveness. Supplementary techniques such as…

Some research indicates that face masks impair identification and other judgements such as trustworthiness. However, it is unclear whether those effects have abated over time as individuals adjust to widespread use of masks, or whether performance is related to individual differences in face recognition ability. This study examined the effect of…

What is bias? A review of the library literature reveals no attempts to define the concept. Nor does it reveal systematic attempts to develop interventions that teach the identification and evaluation of bias. Current pedagogical approaches (checklists and bias charts) tend to assume a self-evident definition that categorises bias as…
