Background: This study explored the physiological correlates of students' self-reported emotions in ecologically valid settings by combining biosignal data (on physical and cardiac activity) and experience sampling method (ESM) data. Aims: The aim was to examine the concurrent associations between self-reported excitement, calmness, anxiety, and…

The aim of this study is to compare the results of correlation coefficient estimation of reliability with those obtained through the Bland-Altman plot technique. The scale was first divided into two halves using three different approaches. A linear and high-level relationship was found between the scale scores obtained from the halved forms.…

This study aims to evaluate students' ability to process the context information embedded in chemistry problems. To achieve this goal, a diagnostic measurement instrument was developed, comprising 28 short-answer items embedded in seven context-based chemistry tasks. Four hundred and ninety-three ninth-graders took part in the testing in Jiangsu,…

In this paper we consider the issue of formality in learning. Both formal and informal learning appear to be well-defined in educational discourse, in contrast with non-formal learning which is less clearly articulated. This lack of clarity around non-formal learning has consequences for its recognition by teachers and learners. To contribute to…

During the August 21, 2017, solar eclipse, high school students measured secondary cosmic ray flux using QuarkNet detectors. These students conducted experiments examining cosmic ray flux, shower, speed of muons, and muon lifetime using QuarkNet cosmic ray muon detectors (CRMDs). These detectors measure muon flux of momenta greater than ~2 GeV, a…

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…

Measuring permeability in a high school physics course has long been a hard task. However, with the advent of using smartphones in the classroom, it is not only possible but even easily done. This paper offers detailed instructions on how to measure permeability using a smartphone's magnetometer, starting with experimentally discovering the…

Teacher empathy has often been considered vital to successful and equitable teaching practices; however, empirical results have been inconsistent as to the effect of teacher empathy on educational outcomes. Further, researchers have questioned the effectiveness of both recent operationalization's of teacher empathy as well as its application in…

This study examines the impact of early Algebra I coursework on advanced Carnegie credits among 12th graders from diverse racial/ethnic backgrounds, using data from the NCES HSTS (1990-2019). Findings indicate that early Algebra students, particularly Black and Latinx, earn more advanced credits, revealing a widening gap in advanced course…

The aim of this study is to understand how students' mathematical thinking is activated and nurtured in solving a modeling problem, where the problem situation involves the design of a system. From a STEM integrated perspective, 9th grade students worked on a modeling task aiming to create an identification system based on hand biometrics. The…

The present article describes the development and validation of the Informational and Normative Conformity Scale (SKI-N), a brief self-report tool capturing adolescents' general propensity to adopt a conformist attitude, and the underlying motives for doing so. The presentation includes a description of scale construction and an assessment of the…

Community colleges are trying to reform their placement procedures from use of a single placement test score to a system that collects multiple measures to be used either as a replacement solitary measure or in conjunction with other measures for more accurate placement into writing courses than what occurred with the placement test, which often…

The teaching and learning of quantum physics has recently become a topic of increasing interest in physics education research. In particular, the study of two-state systems is gaining importance as a means of teaching quantum physics at various educational levels. Meanwhile, a number of approaches have been developed that are also suitable for…

In high school, LC(R)-circuits are an integral component of physics education. We propose a new setup for exploring those circuits utilizing the magnetic field sensor of a smartphone in combination with the application phyphox, which reads and displays sensor input. Coils with high inductance and low resistance generate low frequency oscillations…

Students' emotions in the classroom are highly dynamic and thus typically strongly vary from one moment to the next. Methodologies like experience sampling and daily diaries have been increasingly used to capture these momentary emotional states and its fluctuations. A recurring question is to what extent aggregated state ratings of emotions over…
