Although geometry is important and strongly related to our surroundings, students still have few chances to learn it through practicing in authentic contexts. Therefore, ubiquitous geometric (UG) APP in mobile devices was developed in this study and allowed students to apply and practice geometry in authentic contexts. This study focused on the…

Education research is too often based on gaps in published research or the niche interests of researchers, rather than the priority challenges faced by schools and districts. As a result, the education studies that researchers design and publish are often not applicable to schools' most pressing needs. To spur future research to address the…

Researchers often include covariates when they analyze the results of randomized controlled trials (RCTs), valuing the increased precision of the estimates over the potential of inducing small-sample bias when doing so. In this paper, we develop a sufficient condition which ensures that the inclusion of covariates does not induce small-sample bias…

This paper illustrates similarities and differences between two international surveys that assess adults' skills: the Programme for the International Assessment of Adult Competencies (PIAAC) and the Skills Towards Employment and Productivity (STEP) survey. In particular, the paper highlights the issues that can arise for researchers interested to…

Owing to its recognition as a 21st-century skill, computational thinking (CT) is currently being introduced into school curricula around the world. However, in-service teachers are largely unprepared for this implementation, which, in turn, makes teacher educators (TEds) important stakeholders in preparing prospective teachers to integrate CT into…

This book presents the first results from the third cycle of the IEA International Computer and Information Literacy Study (ICILS 2023). This study investigated how young people are prepared for life in a world where the capacity to use computers and digital information responsibly, safely, and effectively is essential. The study reports on data…

This paper reports a case study, developed in K-12 Portuguese Education, that aimed to analyze the computer science teachers' knowledge, interest, and self-confidence to use educational robotics and other programable objects in classroom activities to teach computer science concepts and to promote students' computational thinking skills. The…

Limited studies exist that connect using signed language with mathematics performance of deaf and hard of hearing children. In the present study, the authors examined 257 participants and compared their results on the Northwest Evaluation Association: Measures of Academic Progress (NWEA MAP) to their results on an assessment of American Sign…

Weighted least squares (WLS), weighted least squares mean-and-variance-adjusted (WLSMV), unweighted least squares mean-and-variance-adjusted (ULSMV), maximum likelihood (ML), robust maximum likelihood (MLR) and Bayesian estimation methods were compared in mixed item response type data via Monte Carlo simulation. The percentage of polytomous items,…

Background and Context: Despite many initiatives to develop Computational Thinking (CT), not much is known about how early programmers develop CT and how we can assess their learning. Objective: Determine if the analysis of students' interactions with an online platform allows understanding the development of CT, how we can convert data collected…

Although students with stronger executive functions (EFs) tend to do better on math computation (MC) assessments than students with weaker EFs, stressful testing situations may lower or affect their mathematical ability. Rumination is one maladaptive coping strategy that can negatively affect EF processes, but little is known about how it impacts…

The purpose of this quantitative, quasi-experimental study was to assess differences between US K-12 teachers who participated in digital game-based learning (DGBL) and those who participated in digital learning (DL), in terms of pre-/posttest gains in computational thinking (CT) and pre-/posttest changes in perceived usefulness (PU) and perceived…

In this paper, an application of open-ended textual feedback is presented as a tool to evaluate the perceptions and needs of teachers tasked with implementing computational thinking in the K-12 curriculum. Semantic analysis tools, including sentiment analysis and thematic analysis, facilitated the identification of common themes in openended…

Pursuant to the criterion of fluency, two types of mathematical achievement tests were used in the present study: simple subtraction (to measure mathematical fluency) and number series completion (to serve as a nonfluency mathematics test). A cohort of 223 d/Deaf and hard of hearing (d/Dhh) students in grades 3-9 in special education schools took…

This study used robot-based practices to develop an activity that incorporated the 6E model. The sixth-grade students learned interdisciplinary knowledge about how to use Arduino electronic components, microcontrollers, and hands-on tools to make a "Crab Robot." In addition, the students learned how to use Scratch programming language to…
