When previous research is cited incorrectly, misinformation can infiltrate scientific discourse and undermine scholarly knowledge. One of the more damaging citation issues involves incorrectly citing article content (called quotation errors); therefore, investigating quotation accuracy is an important research endeavor. One field where quotation…

Scholars have applied automatic content analysis to study computer-mediated communication in computer-supported collaborative learning (CSCL). Since CSCL also takes place in face-to-face interactions, we studied the automatic coding accuracy of manually transcribed face-to-face communication. We conducted our study in an authentic higher-education…

Purpose: The purpose of this study is to investigate how epidemiological and clinical factors collectively predict whether a preschooler who is stuttering will persist or recover and to provide guidance on how clinicians can use these factors to evaluate a child's risk for stuttering persistence. Method: We collected epidemiological and clinical…

Research regarding the role of reading fluency for middle school-aged students with disabilities is limited, particularly for students with attention deficit hyperactivity disorder (ADHD). This study compares the roles--repeated silent reading (RSR), oral reading (OR), and repeated oral reading (ROR)--on grade-level comprehension for students…

Research consistently documents that girls outperform boys in literacy achievement, yet, when considering the starting point--early literacy--we do not have consensus on the origin, meaningful nature, or persistence of such differences. In this two-part study analyzing 5,816 Norwegian students (48.1% girls, average age of 6.1 years), we first…

This paper describes a new automated disengagement tracking system (DTS) that detects learners' maladaptive behaviors, e.g. mind-wandering and impetuous responding, in an intelligent tutoring system (ITS), called AutoTutor. AutoTutor is a conversation-based intelligent tutoring system designed to help adult literacy learners improve their reading…

In Intelligent Tutoring Systems (ITS), methods to choose the next exercise for a student are inspired from generic recommender systems, used, for instance, in online shopping or multimedia recommendation. As such, collaborative filtering, especially matrix factorization, is often included as a part of recommendation algorithms in ITS. One notable…

The present dissertation investigated the impact of scales/scoring methods and prompt linguistic features on the measurement quality of L2 English elicited imitation (EI). Scales/scoring methods are an important feature for the validity and reliability of L2 EI test, but less is known (Yan et al., 2016). Prompt linguistic features are also known…

Naturalistic language learning is contextually grounded. When people learn their first (L1) and often their second (L2) language, they do so in various contexts. In this dissertation I examine the effect of various contexts on language development. Part 1 describes the effects of textual, linguistic context in reading. I employed an eye-tracking…

Although a number of studies have been conducted to explore how various individual difference (ID) factors such as aptitude, motivation, and anxiety contributing to L2 learners' speech performance over a period of time of L2 learning, only a few examined the effect of the three ID factors on learners' L2 speech performances based on classroom…

In the present study we examined whether overlap in language across texts influences the integration of information into a coherent discourse representation for bilingual readers. Across two experiments highly proficient Spanish--English bilinguals read pairs of expository passages describing two fictional science facts while their eye-movements…

Traditionally, content assessments have been carried out through written language. However, the latest standards in U.S. K-12 education expect all students, including English learners (ELs), to demonstrate their content learning using multiple modalities. This study examined the performance of fifth-grade students at varying levels of English…

Block building activities help develop students' spatial reasoning, but few studies focus on the development of block building skills beyond preschool. We worked with four kindergarten, four first grade, and four second grade students to learn more about their Lego block building. We compared students' accuracy, building strategies, and spatial…

Purpose: Narrative assessment is one potentially underutilized and inconsistent method speech-language pathologists may use when considering a diagnosis of developmental language disorder (DLD). However, narration research encompasses many varied methodologies. This systematic review and meta-analysis aimed to (1) investigate how various narrative…

Aim/Purpose: The aim of this paper is to present a systematic review of studies conducted on mobile-assisted task-based learning between 2013 and 2022. The primary objectives of the review are to elicit educational and learning contexts, research areas and foci, research trends, methodologies, data collection techniques, mobile technology used,…
