This experimental study explores whether feedback in the form of standards helps students in giving more accurate performance estimates not only on current tasks but also on new, similar tasks and whether performance level influences the effect of standards. We provided 122 first-year psychology students with seven texts that contained key terms.…

In this brief review, we reflect upon the key contributions of research examining children's eyewitness testimony. Children's testimonial ability became a focus of interest for researchers about 40 years ago in the wake of several high-profile child abuse cases that prompted questions about children's reliability in the face of problematic…

In forensic settings, lay (nonexpert) listeners may be required to compare voice samples for identity. In two experiments we investigated the effect of background noise and variations in speaking style on performance. In each trial, participants heard two recordings, responded whether the voices belonged to the same person, and provided a…

Knowing what kinds of patterns are easy for children to recognize early in their kindergarten year, and what kinds are difficult, can be a useful guide for patterning instruction. Hence, the ability of children to recognize complex patterns early in their kindergarten year was assessed in two experiments. One experiment showed that the children…

This paper describes a very simple, but accurate method of finding the position of the infinity focus of a telescope objective relative to the rear face of its lens cell. The method is easily undertaken in the classroom and provides an opportunity for learners to conduct an interesting and novel optical experiment which introduces thick lens…

Physics education researchers (PER) commonly use complete-case analysis to address missing data. For complete-case analysis, researchers discard all data from any student who is missing any data. Despite its frequent use, no PER article we reviewed that used complete-case analysis provided evidence that the data met the assumption of missing…

Detection of differential item functioning (DIF) is needed in the development of tests to obtain useful items. The Mantel-Haenszel method and standardization are tools for DIF detection based on classical theory assumptions. The study was conducted to highlight the sensitivity and accuracy between the Mantel-Haenszel method and the standardization…

Recollection rejection is traditionally defined as using verbatim traces of old items' presentations to reject new similar test cues, in old/new recognition (e.g., rejecting that "couch" is old by retrieving verbatim traces of "sofa"'s presentation). We broaden this conceptualization to include (a) old as well as new similar…

The Remote Associates Test is a well-established measure, frequently used to assess individuals' creative abilities, as a function of the ability to elicit remote associates. The nature of the involved associative processes is still poorly understood. This hampers a deeper understanding of the creative process, rendering it difficult to determine…

The question: "What is an appropriate role for AI?" is the subject of much discussion and interest. Arguments about whether AI should be a "human replacing" technology or a "human assisting" technology frequently take centre stage. Education is no exception when it comes to questions about the role that AI should…

In the present study, we investigated the accuracy of eyewitness accounts over time from a metacognitive perspective, in which post-retrieval monitoring and control processes play a crucial role in mediating between memory retrieval and ultimate memory performance. In two experiments, participants viewed a narrated slide show depicting ordinary…

Measures of agreement are compared to measures of prediction accuracy within a general context. Differences in appropriate use are emphasized, and approaches are examined for both numerical and nominal variables. General estimation methods are developed, and their large-sample properties are compared.

This paper addresses the question of what should determine whether students' answers to closed questions are marked as correct or incorrect in the context of formal religious education, and when their answers to open ended questions should be given more or less credit. Drawing on insights from Craig Bourne, Emily Caddick Bourne and Clare Jarmy, I…

Accurate assessment of resting metabolic rate (RMR) is necessary for calorie-based recommendations in diet and exercise training interventions. BodyMetrix™ is an ultrasound-based device that provides an estimate of RMR based on body composition, but has not been proven valid or reliable. Therefore, we evaluated the agreement between Katch-McArdle…

This study investigated university students' levels of engagement and accuracy of officiating volleyball during their first Sport Education season. The participants in this study included 20 students (12 male, 8 female) enrolled in a beginner volleyball activity course. The volleyball Sport Education season included 21 lessons that lasted 75 min…
