Applications of polytomous IRT models in applied fields (e.g., health, education, psychology) are abound. However, little is known about the impact of the number of categories and sample size requirements for precise parameter recovery. In a simulation study, we investigated the impact of the number of response categories and required sample size…

Maternal sensitivity during an observed mother-child clean-up task at 18 months and maternal sensitivity during an observed mother-child free-play task at 18 months were tested as independent predictors of child internalizing symptoms, externalizing symptoms, social competence, and language development at 24 months. Participants (n = 292 mothers)…

Boredom has a bad reputation in higher education, as many negative outcomes are associated with this experience. But should boredom be avoided at all costs? Could boredom be guided towards more appropriate, even desirable outcomes -- such as creativity? Through making use of concept analyses to investigate current conceptualisations of boredom and…

Previous research extensively studied reasons for and ways to avoid low response rates, but it largely ignored the primary research issue of the degree to which response rates matter, which we address. Methodological survey research on response rates has been concerned with how to increase responsiveness and with the effects of response rates on…

Background and Context: Students' programming projects are often assessed on the basis of their tests as well as their implementations, most commonly using test adequacy criteria like branch coverage, or, in some cases, mutation analysis. As a result, students are implicitly encouraged to use these tools during their development process (i.e., so…

We conducted a systematic literature review on automated grading and feedback tools for programming education. We analysed 121 research papers from 2017 to 2021 inclusive and categorised them based on skills assessed, approach, language paradigm, degree of automation, and evaluation techniques. Most papers assess the correctness of assignments in…

In March 2020, the higher-education community faced one of its largest disruptions to date with the COVID-19 pandemic forcing campuses to close their doors to thousands of students. The university-wide closures prompted a collaboration between researchers and college administrators to assess the impact of COVID-19 on First-Generation College…

This study aimed to explore stakeholders' perspectives on the ethical considerations for returning individual pharmacogenomics research results to people living with HIV. A qualitative approach to investigation involved five focus group discussions with 30 Community representatives, 12 key informant interviews with researchers, and 12 in-depth…

Background: The research involved 170 adolescents from Brazil and Ecuador, ages 12 to 19, comprising 87 Brazilians and 83 Ecuadorians, with a gender distribution of 95 females and 75 males. Purpose: Examine the correlation between impulsivity, emotional symptoms, and the use of alcohol and drugs among teenagers in these countries. Methods:…

Viewing teacher vulnerability as a pedagogical tool, this comparative case study examined two secondary literacy teachers' use of vulnerability in relation to various instructional goals. Through the analysis of eight video-recorded lessons, we found that teachers demonstrated vulnerability through multiple ways within their literacy instruction…

The purpose of this dissertation was to expand knowledge and theory around instructor social presence in online learning during the COVID-19 pandemic. This study provided a depiction of real-world experiences from the perspective of high school teachers during their shift to online learning amid the COVID-19 pandemic in 2020. The study surveyed 50…

As demonstrated through the experiences of executive administrators who lost their jobs, higher education leaders experience pain when they fail. Leaders at any stage of their life and career can process the pain of failure in constructive ways using a recovery formula built on a "half-life of pain" concept. The time it takes for a…

Educational feedback is a crucial factor in the student's learning journey, as through it, students are able to identify their areas of deficiencies and improve self-regulation. However, the literature shows that this is an area of great dissatisfaction, especially in higher education. Providing effective feedback becomes an increasingly…

Background Study: Peer feedback has been used as an effective instructional strategy to enhance students' learning in higher education. Objectives: This paper reports on the findings of an explorative study that aimed to increase our understanding of the nature and role of peer feedback in the students' learning process in a computer-supported…

Objective: To examine a) whether college students' eating behaviors are different by students' sex and/or body mass index (BMI) categories and b) the correlations between college students' eating behaviors and the degree to which they rely on internal bodily signals for food intake. Participants: Undergraduate college students 18-24 years old at a…
