In a 1984 essay, Benjamin Bloom, an educational psychologist at the University of Chicago, asserted that tutoring offered "the best learning conditions we can devise" and that tutors could raise student achievement by two full standard deviations--or, in statistical parlance, two "sigmas." The influence of Bloom's two-sigma…

This study was conducted to investigate the effects of learning trajectories-based coding (LTs) and LTs-based program on preschoolers' length, area, volume, and angle measurement skills. A quasi-experimental research design was utilized with a quantitative approach. The study's participants were 47 children between the ages of 55-71 months who…

Modern mindfulness is a catch-all term. Just exactly what it looks like within the context of education and how it is taught vastly varies. As such, program fidelity and integrity is questioned. Here a definition of mindful self-regulated learning is proposed and the Mindful Self-Regulated Learning Scale (m-SRLS) is developed. This includes item…

In this paper, a problem set activity focused on understanding and applying unsupervised and supervised chemometric methods for the analysis of biodiesel-diesel blended fuels is described. This problem set was utilized in two upper-level analytical elective courses aimed for junior and senior level students. The data set consists of peak areas…

This study synthesized the research on listening instruction (LI) and its effectiveness on L2 learners' listening competence development based on studies published from 1980 to 2019. After a literature search, well-designed studies that involved not only experimental or quasi-experimental and control groups but also pretests and posttests were…

Data-based instruction (DBI) is a process in which teachers use progress data to make ongoing instructional decisions for students with learning disabilities. Curriculum-based measurement (CBM) is a common form of progress monitoring, and CBM data are placed on a graph to guide decision-making. Despite the central role that graph interpretation…

Almost fifty years ago, Barrows (1986) claimed that problem-based learning (PBL) was broad enough that a single methodological description was not possible. It has only grown more complex since. In addition to meaningful variations of PBL, there are several related problem-centered pedagogies, such as case-based learning, project-based learning,…

The Classroom Strategies Assessment System (CSAS) is a multi-rater, multi-method (direct observation and rating scale methodology) assessment of teachers' use of research-based instructional and behavior management strategies. The present study investigated the association between teacher self-report and school administrator ratings using the CSAS…

More and more teachers create video explanations for their instruction. Whether or not they are effective for learning depends on the videos' instructional quality. Reliable measures to assess the quality of video explanations, however, are still rare, especially for videos created by (preservice) teachers. We developed such a measure in a…

Purpose: Due to the growing complexity involved in leveraging the endless possibilities of ICT on all levels, the technical competence of faculties of higher education institutions (HEI) and effective methods for fostering e-readiness has become questionable. Design/methodology/approach: This research has developed and validated an empirically…

Apparatus catalogues of the first half of the 20th century contain a number of clever and simple devices for measuring the index of refraction of a liquid. In some cases students can put together one of these pieces of apparatus and then make their own measurements. The Gilley board was one of the devices that caught my eye, and I would like to…

Climate change in coastal areas is a complex problem that involves value systems and requires various scientific disciplines. Integration of Science, Technology, Engineering and Mathematics (STEM) approach is needed in learning so that it can train students to think holistically, structured and systematically. This research was carried out with…

Purpose: Scholars are increasingly paying attention to the characteristics of effective citizenship education. The systematic use of data to maximise student learning, also called an output-driven approach, is often presented as a powerful predictor of student outcomes. However, its effectiveness has not been studied in citizenship education.…

Several properties of Earth's magnetic field (field vectors, time dependence) are measured in various locations using a smartphone/tablet magnetic sensor. To enable a proper use of the magnetic sensor as a classroom tool, the exact location of the sensor in the device and its resolution must be identified in a first step. Then, students may…

In the spring of 2020, schools across the United States closed due to the COVID-19 pandemic, forcing a sudden change from the traditional way education was provided. When schools resumed, many teachers found themselves teaching and scaffolding learning in a new situation, online. However, there is limited information on how teachers implement…
