Classical item analysis (CIA) entails summarizing items based on two key attributes: item difficulty and item discrimination, defined as the proportion of examinees answering correctly and the difference in correctness between high and low scorers. Recent insights reveal a direct link between these measures and aspects of signal detection theory…

This quantitative study examined the effects of stored color knowledge on learning achievement and cognitive load using a randomized pretest-posttest control group design. Social media was used to recruit 60 adult participants, randomized into control and experimental groups. A multimedia lesson was presented where the control group viewed images…

The purpose of this mixed-methods study was to determine the extent to which preservice teachers could identify various academic language markers (general academic and discipline-specific vocabulary, passive voice, nominalization, logical connections, and referents--pronouns and synonyms) in complex texts and describe the language that make texts…

The Common Core State Standards have driven an awareness for college and career readiness in schools today. This effort has brought to light the role text complexity plays in the classroom and the importance of students being exposed to complex text. Educators' understanding of complex text and their expectations when choosing text is…

This generic qualitative study examined how mid-to-late career experts in the U.S. space exploration sector transfer tacit knowledge to novices, with a particular focus on fostering employee engagement. Semi-structured interviews were conducted with ten industry experts from various sectors within space exploration. Thematic analysis identified…

Semantic illusions are recognition errors that occur when an individual fails to notice that information contradicts their prior knowledge (Barton & Sanford, 1993; Erickson & Mattson, 1981). For example, after hearing the question, "If a plane crashes while flying over state lines, where should the survivors be buried?" many…

The study examined the difficulties encountered by parents of children with ASD in rural communities in Nigeria. The lack of sufficient healthcare facilities and proficient practitioners in rural locations hinders the availability of early intervention services. The cultural beliefs and misconceptions surrounding ASD exacerbate stigma,…

This study investigated first and second grade teachers' understanding of their students' skill in spelling words of varying difficulty. Specifically, teachers judged their students' item-by-item performance on a twelve-item spelling test adapted from a commercially available developmental spelling inventory. Results showed that teachers'…

This study tested the hypothesis that exploratory learning, with and without analogous problems, would improve students' ability to make connections between conceptually-related topics. In this randomized experiment, undergraduates in introductory physics (N = 171) studied a new topic under three different instructional conditions. Order and type…

Background and Objectives: Graduates from undergraduate nursing programs report inadequate death education. Most death education is focused on end-of-life care and taught by lecture. Students are not provided opportunities to reflect on their own feelings about death. Due to lack of clinical nursing faculty and shortage of clinical sites, students…

There is a pervasive need for school systems to empirically and reliably assess the data literacy and data use skills of their educators (Ingram et al., 2004). With the federal government holding states and school districts accountable for student achievement and the increased emphasis of high stakes testing in schools, it is also critical to be…

This study investigated secondary mathematics pre-service teachers' (PSTs) knowledge of resources in terms of digital technologies, and explored the processes of both selection and integration of technology into their lesson plans. This study employed a case study design. Participants were six secondary mathematics PSTs who enrolled in a methods…

This research investigates students' learning about the electron transport chain (ETC) process in photosynthesis by watching a video followed by playing a serious board game-Electron Chute- that models the ETC process. To accomplish this goal, several learning outcomes regarding the misconceptions students' hold about photosynthesis and the ETC…

Current teaching standards and practices are dictated, at least in part, by state- and district-mandated standardized tests. Yet, despite being surrounded by data, teachers receive only basic trainings on how to use assessments. In reality, teachers use data and assessments daily--even minute by minute--through the assessment process, which uses…

This multiple methods (Denzin, 1978) study investigated two instructional approaches, traditional module and electronic Problem-Based Learning instruction (e-PBL), used within a middle school engineering classroom focused on the variables of engagement, content knowledge, student self-assessment and teacher assessment of problem solving solutions.…
