Block-based visual programming environments are increasingly used to introduce computing concepts to beginners. Given that programming tasks are open-ended and conceptual, novice students often struggle when learning in these environments. AI-driven programming tutors hold great promise in automatically assisting struggling students, and need…

The study examined the relationships between reading comprehension and measures of lower level comprehension skills (vocabulary, grammar, and word processing) and a higher level comprehension skill (inference making), to determine if these measures of higher and lower level comprehension skills predicted different levels of variance in reading…

The aim of the study was to examine nature of science (NOS) views of science teachers in project schools in Turkey. The sub-research questions of the study targeted at the relationships between the teachers' views on NOS in terms of different demographic features of the participant teachers. The participants were composed of convenience sample of…

Three experiments investigated adult learners' acquisition of a novel adjective. In English and other languages, meanings of some gradable adjectives are said to include an absolute standard of comparison (e.g., "full" means completely filled with content). However, actual usage is often imprecise, where a maximum absolute standard of…

In science education, only teachers that are competent in skills, methods and procedures relevant to a science discipline can help learners to develop scientific skills and processes associated with investigating natural phenomena. The purpose of this study was to explore views of pre-service science teachers with regard to science process skills…

This article documents differences between novice and experienced undergraduate students' processes of reading mathematical proofs as revealed by moment-by-moment, think-aloud protocols. We found three key reading behaviors that describe how novices' reading differed from that of their experienced peers: alternative task models, accrual of…

Analysts of discrete data often face the challenge of managing the tendency of inflation on certain values. When treated improperly, such phenomenon may lead to biased estimates and incorrect inferences. This study extends the existing literature on single-value inflated models and develops a general framework to handle variables with more than…

We examined the extent to which the timing of inferential questioning influenced kindergartners' inferencing performance in a non-reading context, while also taking into account individual differences in language comprehension and executive function. Students completed the eight-week Early Language Comprehension Individualized Instruction (ELCII)…

Large-scale standardized tests are regularly used to measure student achievement overall and for student subgroups. These uses assume tests provide comparable measures of outcomes across student subgroups, but prior research suggests score comparisons across gender groups may be complicated by the type of test items used. This paper presents…

This article describes a faculty-led project to assess and revise institutional student learning outcomes at a small urban community college. The revision process involved four stages: (1) exploring stakeholders' explicit and implicit understandings through an experimental assessment; (2) using statistical tools to identify redundancies and…

Network meta-analysis (NMA) is gaining popularity for comparing multiple treatments in a single analysis. Generalized linear mixed models provide a unifying framework for NMA, allow us to analyze datasets with dichotomous, continuous or count endpoints, and take into account multiarm trials, potential heterogeneity between trials and network…

Retrieval practice has been shown to benefit learning. However, the benefit has sometimes been attenuated with more complex materials that require integrating multiple units of information. Critically, Tran et al. "Psychonomic Bulletin & Review, 22," 135-140 (2015) found that retrieval practice improves sentence memory but not the…

Argument-based validation requires test developers and researchers to specify what is entailed in test interpretation and use. Doing so has been shown to yield advantages (Chapelle, Enright, & Jamieson, 2010), but it also requires an analysis of how the concerns of language testers can be conceptualized in the terms used to construct a…

Statistical thinking partially depends upon an iterative process by which essential features of a problem setting are identified and mapped onto an abstract model or archetype, and then translated back into the context of the original problem setting (Wild and Pfannkuch, Int Stat Rev 67(3):223-248, 1999). Assessment in introductory statistics…

Secrets carry valuable social information. Because the content of secrets can be damaging to the secret-keeper's reputation, people should only disclose their secrets to people whom they trust. Therefore, tracking which people know each other's secrets can be used as cue of social relationships: If one person tells another person a secret, those…
