We review the GIDNA and CDM packages in R for fitting cognitive diagnosis/diagnostic classification models. We first provide a summary of their core capabilities and then use both simulated and real data to compare their functionalities in practice. We found that the most relevant routines in the two packages appear to be more similar than…

In this article, we ask the question of what it takes for targeted efforts to be reasonably successful in altering students' misconceptions and unproductive beliefs and ensuing myths about mathematics as a discipline and a school subject and about themselves in relation to mathematics, so as to pave the way for satisfactory learning. We attempt to…

Universal screening is the first mechanism by which students are identified as at risk of failure in the context of multitiered systems of supports. This study examined the validity and diagnostic accuracy of a reading computer-adaptive test as a screener to identify state achievement test performance for third through fifth graders (N = 1,696).…

Nearly three-quarters of public schools in the United States enroll English language learners (ELLs). That means teachers at all grade levels need to know how to help these students achieve full academic English language proficiency. In "Dispelling Misconceptions About English Language Learners," Barbara Gottschalk dispels 10 common…

This article explores an approach to tracking student progress in GCSE courses that yields useful diagnostic information. As well as obtaining an overall score, teachers can learn more about some of the generic characteristics that affect performance.

School resource room guidance personnel handle services to students with disabilities in institutions of higher education in Taiwan. This study conducted a survey of the kind of work performed by university and college resource room guidance personnel, and used a questionnaire to investigate 244 such personnel. This questionnaire contained…

This study investigates modality in textbooks designed for learners of English by exploring the frequency and distribution of modal verbs in two corpora--one of authentic native-speaker language and a pedagogical one used by francophone learners of English in Quebec--with a view to identifying areas where added support for learning may be…

The Diagnostic Assessment and Achievement of College Skills (DAACS) online system assesses newly enrolled college students' skills in reading, writing, mathematics, and self-regulated learning, and provides individualized feedback and links to resources. The purpose of this study is to examine validity evidence regarding the internal structure of…

Students' understanding of models in science has been subject to a number of investigations. The instruments the researchers used are suitable for educational research but, due to their complexity, cannot be employed directly by teachers. This article presents forced choice (FC) tasks, which, assembled as a diagnostic instrument, are supposed to…

The objective of this study is to analyze the Attention Deficit and the Low Performance in the area of English in Children of the Initial Level in the Educational Institution Martina Vizcaino La Raiz, in the Municipality of Maimon, during the first semester of 2018. The instrument was a way to determine their attention deficit and the low…

We propose a conceptual framework which may guide research on fostering diagnostic competences in simulations in higher education. We first review and link research perspectives on the components and the development of diagnostic competences, taken from medical and teacher education. Applying conceptual knowledge in diagnostic activities is…

Intergroup comparison studies have shown that children with specific learning disorders hold lower self-perceptions regarding their abilities than their typically developing peers, especially in an academic setting. This small-scale study investigated the potential effect of diagnostic timing on competency perceptions within a sample of…

Background: This article presents the Afrikaans translation of an originally German diagnostic test for early number concept development. The process of 'importing' a test to South Africa by considering linguistic-, functional-, cultural and metric equivalence is outlined. A theoretical model describes five levels of young children's hierarchical…

Reading is a fundamental skill which changes the achievement trajectory of students, particularly in low-income communities. Children who cannot read proficiently by the upper elementary grades are at-risk for a multitude of poor outcomes, and disparities in the literacy performance of students from culturally and linguistically diverse…

Visual-spatial ability is important for mathematics learning but also for future STEM participation. Some studies report children with dyslexia have superior visual-spatial skills and other studies report a deficit. We sought to further explore the relationship between children formally identified as having dyslexia and visual-spatial ability.…
