This report describes efforts to measure teachers' knowledge of their own students' abilities in mathematics and offers preliminary findings. It provides a description of the sample, a description of the study design and its realization, and descriptive statistics for teacher judgment accuracy. The work described here was completed as part of a…

This study investigates the impact of secondary school students' perceptions of mathematics teachers' formative assessment practices and feedback delivery on their feedback use, and mathematics performance. The sample consisted of 2767 Form 3 (Grade 11) students from 48 secondary schools in Tanzania. Surveys and focus group discussions were used…

The purpose of this study was to answer the following two questions: (1) Do significant differences exist in high-school learning experience, interests, self-efficacy, and career aspirations between male and female science, technology, engineering, and mathematics (STEM) students? (2) Can high-school learning experiences, interests, and…

Concerns about poor L1 reading skills in undergraduate students have been expressed in several contexts. These skills form a basis for building robust L2 reading comprehension skills, vital for translators. This study, which is part of a larger organization-based action research study to improve L1 reading levels, aimed to explore how L1 reading…

This study investigated children's and adolescents' predictions of inclusion and evaluations of exclusion in interracial and same-race peer contexts. The sample (N = 246) consisted of African American (n = 115) and European American (n = 131) children and adolescents who judged the likelihood of including a new peer, evaluated the group's decision…

The development of academic English proficiency and the time it takes to reclassify to fluent English proficient status are key issues in English learner (EL) policy. This article develops a shared random effects model (SREM) to estimate English proficiency development and time to reclassification simultaneously, treating student-specific random…

Recent studies report the cumulative prevalence of behavioral disorders among school-age children to be second only to anxiety disorders. Unfortunately, by the time behavior has been identified as needing special education services, patterns of disruptive and externalizing behavior have often become unremitting. If at-risk behavior can be reliably…

Technology has changed the social landscape and the nature of social interaction. Education has been affected by these changes, as technology has facilitated the creation and Implementation of new educational environments and delivery methods (e.g., distance and blended-learning structures). While the prevalence of such approaches has increased…

We present a proof-of-concept study that sketches the use of compression algorithms to assess Kolmogorov complexity, which is a text-based, quantitative, holistic, and global measure of structural surface redundancy. Kolmogorov complexity has been used to explore cross-linguistic complexity variation in linguistic typology research, but we are the…

This article reports on two studies designed to examine the landscape of online streamed videos, and the features that may support vocabulary learning for low-income preschoolers. In Study 1, we report on a content analysis of 100 top language- and literacy-focused educational media programs streamed from five streaming platforms. Randomly…

Early prediction of student difficulty during long-duration learning activities allows a tutoring system to intervene by providing needed support, such as a hint, or by alerting an instructor. To be effective, these predictions must come early and be highly accurate, but such predictions are difficult for open-ended programming problems. In this…

A common drawback in traditional language education is that all students in the same class use the same content. Since students may have different backgrounds such as prior knowledge and learning speed, one single curriculum may not be able to accommodate every student. Unfortunately, most students cannot afford personalized language learning,…

College resident halls pose a threat for a catastrophic event in the case of fire, but little research has examined potential influences on students' responses to fire alarms, particularly the role of social influence in affecting their behaviors. In the current study, residence hall inhabitants reported their knowledge about fire safety, their…

The ability to judge the limits of one's own knowledge may play an important role in knowledge acquisition. The current study tested the prediction that preschoolers would judge the limits of their lexical knowledge more accurately if they were first exposed to a few objects of contrasting familiarity. Such preexposure was hypothesized to increase…

The work reported here involved a comparative study regarding the understanding that high school students (16-18 years) have of the concept of chemical elements and their periodic classification. More specifically, the level of knowledge on this topic was compared before and after the completion of baccalaureate studies in a sample of Spanish…
