Most biology undergraduates learn about mutations in multiple classrooms throughout their college career. Understanding personalised genome test results, genome editing controversies, and the appearance of new variants of viruses or antibiotic resistant bacteria all require foundational knowledge about mutations. However, the abstract nature of…

This study examined the clinical utility of the Massachusetts Youth Screening Instrument--Second Version (MAYSI-2) among African American (AA) incarcerated youth and used White incarcerated youth as a comparison group. Data were analyzed for 314 incarcerated youth (193 AA offenders and 121 White offenders) of ages 13-17 years who were adjudicated…

The Performance Assessment for Leaders (PAL) was developed by a team of nationally recognized experts in response to a Massachusetts requirement to determine and evaluate the leadership abilities of candidates seeking initial school principal licensure. This article describes and evaluates research conducted on all aspects of a 2014-2015 statewide…

In this article, we report on a mixed method study conducted through a previously validated bilingual instrument. The purpose was to understand elementary bilingual and dual language (BDL) teachers' perspectives of science and engineering (S&E) teaching in Massachusetts and Puerto Rico with the goal of developing situated professional…

Learning problems (LP) can have wider implications than the academic deficits per se. The goal of the present series of studies was to develop a reliable and valid quality-of-life measure targeted to children and adolescents with LP. In Study 1, using a 35-item questionnaire, we surveyed 151 parents/guardians of children referred for assessment of…

Background: Recent efforts supporting children's dietary behaviors suggest the importance of food literacy (FL), which is a multidimensional concept that encompasses food-related knowledge, skills, and behaviors. To date, FL has been largely informed by adult and adolescent research. Aims: To assess the FL experiences, perceived skills, and…

The paper presents the conceptual basis of the theories: Behaviorism, Gestalt, Cognitive Psychology, and the Historic-Cultural Psychology. The essential categories of these theories were validated in a population of 2704 courses at the Massachusetts Institute of Technology, MIT (USA). The research seeks the relationship of theories with course…

After three decades of scholarship describing why and how students ought to be taught to think historically, this study asks what happens when they are. Ten high school students from a school that incorporated historical thinking into all history coursework repeated the think-aloud task from Wineburg's 1991 study of the cognitive processes…

Asking students to raise their hands is a time-honored feedback mechanism in education. Hand raising allows the teacher to assess to what extent a concept has been understood, or to see where the class stands on a particular issue, and then to proceed with the lesson accordingly. For many types of questions, as the evidence here demonstrates, the…

This mixed methods study examines perspectives on failure in the classroom by elementary teachers new to teaching engineering. The study participants included 254 teachers in third, fourth, and fifth grade who responded to survey questions about failure, as well as a subset of 38 of those teachers who participated in interviews about failure. The…

The purpose of this study was to provide further validation a new measure of mental toughness in sport. The Inventory of Mental Toughness Factors in Sport (IMTF-S) was originally developed and validated using principal component analysis. For the present study, the psychometric properties of the IMTF-S were again evaluated, but by way of the Rasch…

There is empirical evidence to suggest that oral language and vocabulary on entering kindergarten are the best predictors of later reading success. Identifying skills that are predictive of later achievement using psychometrically sound measurement methods is a necessary component of early intervention efforts. Currently, there are limited methods…

Background: Expressed emotion (EE) is a measure of family emotional climate found to be predictive of symptom levels in a range of psychiatric, medical, and developmental disorders, including autism. Method: Employing data from 104 mothers of children with autism, this study examines the Autism-Specific Five Minute Speech Sample (AFMSS), a…

Readers differentially adopt an agent's perspective as a function of pronouns encountered during reading. The present study assessed the reliability of this effect across narrative contexts and self-reported variation in levels of engagement during reading. Experiment 1 used an extended sample (N = 263) and replicated an interactive influence of…

Objectives: To determine (1) reliability of new food environment measures; (2) association between home food environment and fruit and vegetable (FV) intake; and (3) association between community and home food environment. Methods: In 2005, a cross-sectional survey was conducted with readministration to assess test-retest reliability. Adolescents,…
