Audit correspondence studies are field experiments that test for discriminatory behavior in active markets. Researchers measure discrimination by comparing how responsive individuals ("audited units") are to correspondences from different types of people. This article elaborates on the tradeoffs researchers face between sending audited…

Single-case experimental designs (SCEDs) are a useful tool for evaluating the effects of interventions at an individual level and can play an important role in the development and validation of evidence-based practices. Historically, researchers relied on visual analysis of SCED data and eschewed statistical approaches. Although researchers…

Institutional ethics review procedures aim -- in principle -- to minimise harm and evaluate risks, providing an important space to consider the safety of participants and researchers. However, literature has questioned the effectiveness of the process, particularly for reviewing 'risky' topics in a risk-averse environment. This article reports the…

To draw informed conclusions from research studies, research consumers need full and accurate descriptions of study methods and procedures. Preregistration has been proposed as a means to clarify reporting of research methods and procedures, with the goal of reducing bias in research. However, preregistration has been applied primarily to research…

Teacher coaching is a powerful form of professional learning that improves teaching practices and student achievement, yet little is known about the specific aspects of coaching programs that are more effective. Researchers used a blocked randomized experiment to study the effects of one-to-one coaching on teacher practice. When pooled across all…

Many studies have shown the difficulties of learning and teaching the decimal number system for whole numbers. In the case of numbers bigger than one hundred, complexity is partly due to the multitude of possible relationships between units. This study was aimed to develop conditions of a resource which can help teachers to enhance their teaching…

"The Belmont Report" was written in 1979 to address the abuse of human participants in biomedical research. In the report, three ethical principles were described: (1) "beneficence," which describes an act of charity or kindness that maximizes possible benefits while minimizing possible harms; (2) "justice," described…

This article describes an artistic inquiry conducted by two art therapists using a dialogic method of collage and letter writing over a period of 4 weeks. The goal of the project was to broaden understanding of arts-based research and to discover the properties of collage as a research practice in art therapy. A thematic analysis of the visual and…

Suppose one observes a correlation between two events, B and C, and infers that B causes C. Later one discovers that event A explains away the correlation between B and C. Normatively, one should now dismiss or weaken the belief that B causes C. Nonetheless, participants in the current study who observed a positive contingency between B and C…

Until recently, it was generally assumed that the ability to attribute false beliefs did not emerge until about 4 years of age. However, recent reports using spontaneous- as opposed to elicited-response tasks have suggested that this ability may be present much earlier. To date, researchers have employed two kinds of spontaneous-response…

This article distinguishes between six tasks related to the academic researcher role: (1) networking; (2) collaboration; (3) managing research; (4) doing research; (5) publishing research; and (6) evaluation of research. Data drawn from surveys of academic staff, conducted in Norwegian universities over three decades, provide evidence that the…

In their paper, Meara and Olmos Alcoy (2010) attempted to find a means of estimating productive second language (L2) vocabulary size based on the premise that many known lexical items simply do not appear in learner-produced texts. To do so, they borrowed an ecological model, in which a capture-recapture formula, the Petersen estimate, is used to…

Teachers and researchers are considered epistemic authorities that provide reliable information if that information is relevant to their discipline. Students differentiate between relevant and irrelevant disciplines when assessing teachers' expertise. In this paper, it is investigated whether students' cultural-educational background plays a role…

We surveyed researchers in the health and exercise sciences to explore different areas and magnitudes of bias in researchers' decision making. Participants were presented with scenarios (testing a central hypothesis with p = 0.06 or p = 0.04) in a random order and surveyed about what they would do in each scenario. Participants showed significant…

This essay reviews progress in empirical economics since Leamer'rs (1983) critique. Leamer highlighted the benefits of sensitivity analysis, a procedure in which researchers show how their results change with changes in specification or functional form. Sensitivity analysis has had a salutary but not a revolutionary effect on econometric practice.…
