Graph theory allows the student to work on problems that require imagination, intuition, systematic exploration, conjecturing, and reasoning. It implies that mathematical investigation skill is essential to be proficient in Graph Theory. In this study, we conduct empirical research that deals with associational research. There were 97 students…

People have difficulty sighting missing persons, partially because people's limited cognitive resources are required for searching. As a result, people sometimes do not devote resources to searching. This research will examine whether empathy increases the resources devoted to searching and search performance. In Experiment 1, we will manipulate…

The determination of the speed of sound in air is a classical experiment, usually performed with a resonance tube apparatus. The measured value can be checked against Eq. (1), which describes the temperature dependence of the speed of sound in dry air. A modern implementation of this speed of sound investigation uses an Arduino Uno microcontroller…

One of the well-known approaches to creativity differentiates between creative person, process, product, and press. In the study presented in this paper we focus on creative process and product associated with Problem Posing through Investigation (PPI) by experts in mathematical problem solving. We link the creative process to creativity of PPI…

One of the ways in which students can be taught science is by doing science, the intention being to help students understand the nature, processes, and methods of science. Investigative research projects may be used in an attempt to reflect some aspects of science more authentically than other teaching and learning approaches, such as confirmatory…

In May 2023, the Civil Rights Division (the Division) of the U.S. Department of Justice and the Office for Civil Rights (OCR) at the U.S. Department of Education jointly released this Resource on Confronting Racial Discrimination in Student Discipline. The Resource demonstrates the departments' ongoing commitment to the vigorous enforcement of…

This paper describes the creation of a theme-based first quarter, of a two quarter sequence, general chemistry laboratory course following an argument driven inquiry format and employing specifications grading. The course contains four, two-week projects investigating the chemistry of a popular sports drink. The sugar content, dye concentration,…

In this research, our objective is to characterize the problem-solving procedures of primary and lower secondary students when they solve problems in real class conditions. To do so, we rely first on the concept of heuristics. As this term is very polysemic, we exploit the definition proposed by Rott (2014) to develop a coding manual and thus…

Statistics has been a content domain in the mathematics curriculum for decades. However, statistics is a distinct discipline from mathematics and there are important differences in how one should teach the two disciplines. In this article, the authors consider how these differences can inform an adaptation to the 5 Practices for Orchestrating…

Through quantitative research, this study seeks to identify the specific method campus police employ to investigate cybercrime, then identify demographic characteristics (variables) of the agencies that permit or limit the agency's method of response. The correlation between demographic characteristics and the resulting response method represents…

Children (N = 278, 34-71 months, 54% girls) were told which of two figurines turned on a music box and also observed empirical evidence either confirming or conflicting with that testimony. Children were then asked to sort novel figurines according to whether they could make the music box work or not. To see whether children would explore which…

The refinement of soft skills is essential to the success of athletic training students. Yet, more work is needed to identify desirable educational techniques to support the progression of soft skills in athletic training education. The current study identified professional athletic training students' (10 students; 21.2 ± 2.1 years) perceptions of…

There is now a significant research literature devoted to reconceptualizing scientific activities, such as modeling, explanation, and argumentation, to realize a vision of science-as-practice in classrooms. As yet, however, not all scientific practices have received equal attention. "Planning and Carrying out Investigations" is one of…

Scholars have documented a tendency of (semi-)authoritarian regimes to undermine university autonomy, mainly through organizational (de jure) changes. This paper presents a case study of a publicly triggered plagiarism investigation by the University of Belgrade into the doctoral thesis of the Serbian Minister of Finance, one of the key members of…

The ideal gas law, "PV = nRT," is one of the simplest physical laws in nature that is introduced to students as early as in high school and first year in college. In this equation, "P" stands for pressure, "V" is the volume, "n" is the amount expressed in mole, "T" is the temperature in Kelvin…
