Background/Context: In meta-analysis examining educational intervention, characterizing heterogeneity and exploring the sources of variation in synthesized effects have become increasingly prominent areas of interest. When combining results from a collection of studies, statistical dependency among their effects size estimates will arise when a…

This article uses the interventionist theory of causation, a counterfactual theory taken from philosophy of science, to strengthen causal analysis in process tracing research. Causal claims from process tracing are re-expressed in terms of so-called hypothetical interventions, and concrete evidential tests are proposed which are shown to…

People have difficulty sighting missing persons, partially because the task requires people's limited cognitive resources. We examined whether empathy increases search behaviors and performance. We manipulated empathy felt toward a formerly (E1) and actively (E2) missing person. We measured willingness to volunteer to search for missing people in…

With a call for schools to infuse data across the curriculum, many are creating curricula and examining students' thinking in data-intensive problems. As the discipline of statistics education broadens to data science education, there is a need to examine how practices in data science can inform work in K-12. To better understand how to frame data…

In existing studies of investigative interviewing, the effects of interviewing contexts have often been measured with little consideration of the reciprocal interviewee's stable characteristics. To clarify the factors and conditions under which adults are likely to retain accurate information and be resistant (or vulnerable) to suggestions during…

Learning to plan modeling-based investigations (MBIs) presents significant challenges for pre-service elementary teachers. Although they understand disciplinary core ideas and modeling practices, they address both as competing learning goals and, as novices, they have not experienced how to structure MBIs for their future students. In the context…

Facial examiners make visual comparisons of face images to establish the identities of persons in police investigations. This study utilised eye-tracking and an individual differences approach to investigate whether these experts exhibit specialist viewing behaviours during identification, by comparing facial examiners with forensic fingerprint…

This laboratory experiment aims to provide undergraduate students with research experience in water treatment by membrane separation. This experiment includes fabrication and characterization, as well as water treatment applications of the interfacially polymerized polyester nanofiltration membranes. Through participating in this experimental…

According to the Diagnostic Feature-Detection (DFD) hypothesis, the presence of fillers that match the eyewitness's description of the perpetrator will boost discriminability beyond a showup, and very few fillers may suffice to produce the advantage. We tested this hypothesis by comparing showups with simultaneous lineups of size 3, 6, 9, and 12.…

Biology teachers' attitudes play a vital role in successful scientific investigations. Some biology teachers situated in the central part of South Africa experience challenges that include a lack of the necessary scientific knowledge and skills, which hinders the presentation of scientific investigations. These challenges adversely influence these…

The use of investigations in science teaching is both common and commonly advocated for in science education literature. We suggest that the use of investigations should differ depending on the complexity of the subject matter. That complexity can vary depending on both the nature of the information and students' expertise levels. The present…

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…

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…

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…
