Background: YouTube is widely used for learning about scientific issues in and out of school. However, much of the scientific information on YouTube is inaccurate. Prior studies have mostly focused on how students evaluate textual online information sources and have not yet systematically examined how they evaluate authentic scientific YouTube…

In test equating, one critical equating property is the group invariance property which indicates that the equating function used to convert performance on each alternate form to the reporting scale should be the same for various subgroups. To mitigate the impact of disrupted learning on the item parameters during the COVID-19 pandemic, a…

Justifications play a central role in argumentation, which is a core topic in school science education. This paper contributes to this field of research by presenting two studies in which we assess students' justifications for supporting or rejecting hypotheses in the physics lab based on self-collected, anomalous experimental data, which are…

Practical activities are the main activities of learning biology whose implementation is rarely evaluated. This study aimed to determine the quality of biology practicum which includes planning and implementation of biology practicum and student learning outcomes thereafter. The population in this study was students, teachers and and laboratory…

Experienced middle school mathematics and science teachers were recruited for a pilot study. The teachers separately responded to a survey related to determining expected learning outcomes based on their traditional teaching, classroom experiences and observations, and self-brainstorming. The teachers then received training on how to design,…

Students' ability beliefs about running activities in physical education/athletics classes were investigated longitudinally from the perspectives of Nicholls' conceptions of ability and Dweck's implicit theories of ability. The data for this study were provided by 44 students (20 boys; 24 girls) who participated in a larger longitudinal project on…

Purpose: This study examined the prevalence of different weight status and the relationships between weight status and physical fitness among Chinese children and youth. Methods: Participants were 107,206 Grade 4 children and 70,213 Grade 8 youth from the China National Assessment of Educational Quality -- Physical Education & Health in 2015…

Background/Context: Regression discontinuity (RD) designs are used for policy and program evaluation where subjects' eligibility into a program or policy is determined by whether an assignment variable (i.e., running variable) exceeds a pre-defined cutoff. Under a standard RD design with a continuous assignment variable, the average treatment…

The purpose of this research study was to learn about students' conceptions concerning the line of best fit just prior to their introduction to the topic. Task-based interviews were conducted with thirty-three students, focused on five tasks that asked them to place the line of best fit on a scatterplot and explain their reasoning throughout the…

Research shows that teachers' grading is influenced by non-achievement factors in addition to official criteria, such as knowledge and skills. Some grading criteria are internalised by the teacher, who is sometimes unable to verbalise the criteria used and refers to what is called a "gut feeling". Therefore, transparency, validity and…

Approximately one-third of American freshmen at two-year and four-year colleges require remedial coursework and over 40 percent of employers rate new hires with a high school diploma as "deficient" in their overall preparation for entry-level jobs. Yet, over the past decade, as these students marched through America's public education…

Given that there is no universal way to measure implementation fidelity, instructional designers developing instructional innovations may find themselves faced with the challenge of determining the extent to which teachers' implementation of an instructional model is faithful. This article contends that a faithful implementation is one in…

Background: Research on physical fitness often regards socioeconomic status (SES) as a confounding factor. However, few studies investigate the impact of SES on fitness. This study investigated the impact of SES on physical fitness in both males and females, with an economic-based construct of SES. Methods: The sample consisted of 954 6th, 7th,…

The purpose of this study was to identify the impact the implementation of the Baldrige Education Criteria had on the mathematics portion of the Texas Assessment of Knowledge and Skills (TAKS) for eighth grade at-risk students. The three research questions (a) examined the effects the Baldrige Education Criteria had on individual institutions over…

The "Common European Framework of Reference" (CEFR; Council of Europe, 2001) provides a competency model that is increasingly used as a point of reference to compare language examinations. Nevertheless, aligning examinations to the CEFR proficiency levels remains a challenge. In this article, we propose a new, level-centered approach to…
