Background: In examining associations of sexual orientation, school connectedness (SC), and depression, no studies have used a continuum of sexual orientation. Additionally, no study has examined whether individuals with higher SC within subgroups of the continuum of sexual orientation are protected from symptoms of depression when compared to…

In the context of introductory physics, we study student conceptual understanding of differentials, differential products, and integrals and possible pathways to understanding these quantities. We developed a multiple choice conceptual assessment employing a variety of physical contexts probing physical understanding of these three quantities and…

Although content validity--how well each item of an instrument represents the construct being measured--is foundational in the development of an instrument, statistical validity is also important to the decisions that are made based on the instrument. The primary purpose of this study is to demonstrate how simulation studies can be used to assist…

The aim of this study is to update the Turkish version of the Revised Cyber Bullying Inventory (RCBI) and eliminate specific technology names. Validity and reliability tests were carried out with 1,803 high school students. The updated version of the RCBI yields valid and reliable scores measuring cyberbullying and victimization.

Mobile technology opens a new avenue for teaching and learning mathematics in schools in the 21st century. This study determined the effects of using a mobile application in teaching mathematics among Grade 8 students of a public national high school, Cebu City, Philippines. The researchers used the quasi-experimental method of research using the…

The Jefferson Scale of Empathy (JSE) is a broadly used instrument developed to measure empathy in the context of health professions education and patient care. Evidence in support of psychometrics of the JSE has been reported in health professions students and practitioners with the exception of osteopathic medical students. This study was…

International standardized tests are showing an underperformance of students in geometry and spatial ability relative to other content domains. In this research, we examined the relationship between a teacher's judgment of third- and fourth-grade students' geometry and spatial ability (i.e., grades), three spatial ability tasks (Water-Level-Task,…

Data from the Autism Inpatient Collection was used to examine the relationship between problem behaviors and verbal ability, which have generally, though not universally, been highly associated. In a comparison of 169 minimally-verbal and 177 fluently-verbal 4 to 20-year-old psychiatric inpatients with ASD, the severity of self-injurious behavior,…

The study investigated the effect of a Target-Task Approach on the performance of advanced level chemistry students in electrochemistry. The study adopted the quasi-experimental research design. Data were obtained from two advanced level chemistry classes from two high schools in Gweru, Zimbabwe. One of the two classes was assigned to be the…

Background: People with intellectual and developmental disabilities (IDD) may be at risk for medication-related problems due to complex medication regimens. The objective of this study was to determine the medication regimen complexity of adults with IDD. Methods: This retrospective study compared the Medication Regimen Complexity Index (MRCI)…

The purpose of the present study was to investigate the preliminary structural, convergent, and incremental classification validity of responses to the Subjective Academic Problems Scale (SAPS), which is a seven-item self-report behavior rating scale intended for use as a triaging tool within secondary-level school mental health screening…

Flipped learning has an almost 20-year history. However, the research is as ambiguous as it has been since its inception. This pedagogical model lacks consistent results. One key component that does have an impact, but not the only factor, has been an active or dynamic component included into the learning environment. The goal of this study was to…

In the research, "Questionnaire on Individual Instrument Course Burnout" developed by Girgin, "Questionnaire on Individual Instrument Training habits" developed by Küçükosmanoglu, Babacan, Babacan and Yüksel, and "Questionnaire on Perceived Family Support for Individual Instrument Course" developed by Girgin were…

Parenting a child with autism spectrum disorder (ASD) can be stressful. Understanding parent's perceptions of their stress and their child's ASD-related symptoms is important for both the well-being of parent and child and for other reasons, such as intervention adherence and diagnostic accuracy. We report parent (N = 570) ratings of both their…

The main objective of this research is to find out whether rate-buildup reading, skimming, and scanning strategies applied in hybrid learning method help students boost their reading speed and comprehension. This research employed quasi-experimental design. 15 students were involved into experimental group and 15 were enrolled into control group.…
