Comparative interrupted time series (CITS) designs evaluate impact by modeling the relative deviation from trends among a treatment and comparison group after an intervention. The broad applicability of the design means it is widely used in education research. Like all non-experimental evaluation methods however, the internal validity of a given…

The COVID-19 pandemic provided an opportunity to explore how different modes of learning may impact student achievement. Little research has been conducted regarding how the pandemic may have affected students' reading skills. The problem addressed in this study was that the effects of varying and inconsistent learning environments for Title I K-2…

Statistical methods are indispensable to the practice of science. But statistical hypothesis testing can seem daunting, with P-values, null hypotheses, and the concept of statistical significance. This article explains the concepts associated with statistical hypothesis testing using the story of "the lady tasting tea," then walks the…

We use analogies to provide introductory laboratory students intuition into measurement uncertainties. Using a battery-resistor circuit we discuss uncertainty concepts and derive expressions for uncertainty of the mean and sums of uncertainties. Finally, we draw attention to the fact that the interpretation of standard deviation as uncertainty…

We propose a method of generating teaching policies for use in intelligent tutoring systems (ITS) for concept learning tasks [1], e.g., teaching students the meanings of words by showing images that exemplify their meanings à la Rosetta Stone [2] and Duo Lingo [3]. The approach is grounded in control theory and capitalizes on recent work by [4],…

This study statistically analyzes data from 756 evangelical and Latter-day Saint youth regarding their perceived in-class spiritual experiences of twenty items related to Christian theology. The data indicates similar spiritual outcomes between the two groups, with no statistically significant differences between eleven of the twenty spiritual…

This study aims to compare the perceptions and self-efficacy skills of primary school teachers who have taken drama courses to those who have not in terms of the use of drama as a teaching technique. The sample of the study consists of prospective second and third grade teachers enrolled in the Primary School Teaching Department at Ahi Evran…

We investigated whether the implementation of a scaffolded case study assignment could increase student perceptions of their scientific literacy (SL) skills in a third year Nutritional Science course. The change in students' SL perceptions were assessed by the completion of two surveys (administered at the start and end of the semester) consisting…

This study aimed to establish whether 5- to 7-year-old children with developmental language disorder (DLD) have difficulties explaining actions in terms of intentions and if so, to elucidate the nature of such difficulties. Children with DLD and typically developing chronological age peers (TD group) participated in a production task designed to…

Drawing appropriate diagrams is a useful problem solving heuristic that can transform a problem into a representation that is easier to exploit for solving it. One major focus while helping introductory physics students learn effective problem solving is to help them understand that drawing diagrams can facilitate problem solution. We conducted an…

This is an experimental study and it was aimed to identify the effects of 8-week plyometric training of hearing-impaired athletes on balance. 24 Male hearing-impaired volleyball players participated in the study. Random method was used when experimental and control groups were identified. Subjects used in the study were divided into two groups as…

There are several different methods of learning motor skills, like traditional (linear) and differential (nonlinear) learning training. The traditional motor learning approach proposes that learners improve a skill just by repeating it. According to the teaching principles, exercises are selected along continua from easy to hard and from simple to…

A randomized controlled trial was conducted to determine the efficacy of "U-Pace" instruction for older undergraduates, ages 25 and older, and younger undergraduates, ages 18 to 24. Additionally, change in learner perceptions across the semester, an outcome not reported in the literature on "U-Pace" instruction, was…

Students with ADHD struggle in higher education as a result of various functioning and participation problems. However, there are remaining gaps in the literature. First, it remains unclear how often and during which teaching and evaluation methods problems arise. Second, we do not yet know which reasonable accommodations are most effective to…

The purpose of this quantitative retrospective causal-comparative study was to determine to what extent the form of professional development (face-to-face or online) or the level of instruction (elementary or high school) has on classroom teaching practices as measured by student learning outcomes. The first research question sought to determine…
