Intervention and education programs for autistic individuals have been greatly informed by the medical model of disease/disability. Under this model, autism is seen as something to be fixed or remediated, and interventions have often focused on reducing autistic traits in an effort to get the autistic person to appear more "typical."…

Within physics education research (PER), resource theory has proven to be a useful framework for investigating knowledge and learning and informing instructional design. To analyze learning over longer timescales and across cases, PER scholars must first identify and describe the resources activated within and across physics contexts and domains.…

In line with the journal volume's theme, this essay considers lessons from the past and visions for the future of test validity. In the first part of the essay, a description of historical trends in test validity since the early 1900s leads to the natural question of whether the discipline has progressed in its definition and description of test…

Since Gisela Granena's influential work, LLAMA D v2, a sound recognition subtest of LLAMA aptitude tests, has been used as a measure of implicit learning aptitude in second language acquisition research. The validity of this test, however, is little known and the results of studies with this instrument have been somewhat inconsistent. In this…

The extent to which an intervention is perceived as socially valid significantly influences whether the intervention is selected, implemented, and maintained (Kern & Manz, 2004). Social skill interventions and evidence-based practices are often ranked with low social validity by adolescents (McCoy et al., 2016). Interventions delivered through…

This study serves as an initial attempt to establish content validity for graphs likely to be included in trainings targeting progress monitoring for professionals serving learners with or at risk for disabilities. We created a survey containing 32 graphic displays of hypothetical learner data. These surveys were administered to a sample of…

Recent research seeks to develop more comprehensive learner models for adaptive learning software. For example, models of reading comprehension built using data from students' use of adaptive instructional software for mathematics have recently been developed. These models aim to deliver experiences that consider factors related to learning beyond…

Individuals with autism spectrum disorders and other developmental disabilities (ASD/DD) often need to be explicitly taught personal hygiene skills (e.g., menstrual care, penile care and washing and cleaning of intimate body parts). The taboo and private nature of intimate care skills has often led practitioners to avoid teaching these skills…

Instructional coaching, informed by observation tools that measure teachers' practices, has been effective in improving teaching quality in early learning programs. However, existing measurement tools limit teachers' abilities to implement this type of instructional coaching at scale. To address this challenge, a team at SRI Education, along with…

The impact of the social determinants of health (SDH) on health outcomes is receiving increased attention. Health profession students need to learn about SDH; however, there are no validated tools to measure student competence in assessing SDH. There is a need for a brief, valid instrument to measure student competency and knowledge of SDH. This…

The Critical Race Theory Measurement (CRTM) was developed to evaluate the understanding of the six major principles of CRT and the significance of race relating to the preparation of practitioners providing services to people of color. The objective of this study was to evaluate the scale's psychometric properties. The CRTM self-assessment…

This study introduced the Scale of Adolescents' Perceptions Toward Adults (SAPTA), which was developed in Turkey. The validity and reliability study for SAPTA was performed using the data obtained from 1008 high school students whose ages ranged between 14 and 18. The internal consistency coefficient calculated with the Explanatory Factor Analysis…

We evaluated the validity of using the GRE General Test to assist with graduate school admissions for individuals with disabilities. We studied a sample of 16,239 graduate students from 10 U.S. research universities in three groups: students without any reported disabilities, students who reported disabilities and took the computer-delivered GRE…

Using mixed methods to develop new scales is not a new idea since the 2000s. However, there exists inadequate literature that discusses scale development using mixed methods, with steps including how to design the study, how to implement the process, and how to conduct validation. This study proposes a hands-on model of using mixed methods to…

The current study examined the criterion validity of a computer adaptive universal screener with an end-of-year state mathematics assessment using extant data provided by a local education agency. Participants included 1,195 third through eighth graders. Correlational analyses were used to report predictive and concurrent validity coefficients for…
