Acid-base chemistry is a key reaction motif taught in postsecondary organic chemistry courses. More specifically, concepts from the Lewis acid-base model are broadly applicable to understanding mechanistic ideas such as electron density, nucleophilicity, and electrophilicity; thus, the Lewis model is fundamental to explaining an array of reaction…

This qualitative single case study explored how general education middle school teachers implement the three tiers of the Multi-Tiered Response to Intervention (MTSS/RTI) model while delivering differentiated core curriculum instruction. The conceptual framework included the differentiated strategies of Fleming and Mills' (1992) Visual, Aural,…

We present an analysis of log data from a semester's use of the OpenDSA eTextbook system with the goal of determining the most difficult course topics in a data structures course. While experienced instructors can identify which topics students most struggle with, this often comes only after much time and effort, and does not provide real-time…

To help teachers implement new, research-based approaches for leveraging technology to improve science, technology, engineering and mathematics (STEM) learning, a systematic review of the research literature on the impact of integrating innovative digital technology in STEM and computer science curricula and classrooms was conducted. For purposes…

This paper reports on a case study conducted in an American university investigating the role of feedback within a distance education environment. Based on data gathered from online and hybrid undergraduate students in a teacher education program and supported by existing research, we describe how we support online learners by implementing a…

The COVID-19 pandemic has led to an unprecedented shift in how health science education is delivered (Sandars et al., 2020). With face-to-face learning, such as lab and classroom interactions, largely unavailable during the pandemic, institutions have been required to quickly shift the learning environment to a fully virtual format. While…

The responsibility for college success has historically rested with the student, but since the 1980s, educators have taken increasing ownership of this, designing structures that increase the likelihood of learning, success, and retention. These efforts have included a variety of initiatives--first year seminars, learning communities,…

Improving student performance for high-need student populations by improving the use of data in decision-making for early reading intervention programs in northwest Florida is the focus of this research to practice effort. The study is conceptually based on using a relational-feedback intervention (RFI) database model in early learning…

The present study seeks to evaluate a hybrid model of identification that incorporates response to instruction and intervention (RTI) as one of the key symptoms of reading disability. The 1-year stability of alternative operational definitions of reading disability was examined in a large-scale sample of students who were followed longitudinally…

The Florida Center for Reading Research (FCRR) Reading Assessment (FRA) consists of computer-adaptive reading comprehension and oral language screening tasks that provide measures to track growth over time, as well as a Probability of Literacy Success (PLS) linked to grade-level performance (i.e., the 50th percentile) on the reading comprehension…

District implementation of the response to intervention (RTI) model has occurred at a surprising rate. It appears that implementation of RTI has occurred rapidly and is being implemented with all students. Rapid implementation of RTI is occurring alongside continued controversy over the model and its intended uses. Although significant research…

This study examines model selection indices for use with dichotomous mixture item response theory (IRT) models. Five indices are considered: Akaike's information coefficient (AIC), Bayesian information coefficient (BIC), deviance information coefficient (DIC), pseudo-Bayes factor (PsBF), and posterior predictive model checks (PPMC). The five…

The effects of combining video modeling by experts with video feedback were analyzed with 4 female competitive gymnasts (7 to 10 years old) in a multiple baseline design across behaviors. During the intervention, after the gymnast performed a specific gymnastics skill, she viewed a video segment showing an expert gymnast performing the same skill…

Five 1st-grade teachers read aloud two Caldecott Award-winning picture books to their classrooms of diverse, urban students. In this two-phase study, researchers analyzed teachers' transcripts for common elements, interviewed 1st-graders and focused on one teacher's read-aloud events while comparing them with her students' responses. Findings…

Excessive college course withdrawals are costly to the student and the institution in terms of time to degree completion, available classroom space, and other resources. Although generally well quantified, detailed analysis of the reasons given by students for course withdrawal is less common. To address this, a text mining analysis was performed…
