Background: This study is a part of a larger research project where the effect of instructional guidance in terms of role definition and role switching was investigated on students' learning of Basic Life Support (BLS) during a 20-minute reciprocal learning episode with task cards. BLS is a lifesaving skill consisting of nine sub skills to be…

This study investigates the effectiveness of an elective course titled, "Microteaching in Teacher Education" (MiTEc) which is offered to the 3rd and 4th year pre-service science teachers. This course aims to provide pre-service teachers with meaningful experiences and prepare them for real-classroom settings. During the study,…

Eyewitnesses typically recount their experiences many times before trial. Such repeated retrieval can enhance memory retention of the witnessed event. However, recent studies (e.g., Chan, Thomas, & Bulevich, 2009) have found that initial retrieval can exacerbate eyewitness suggestibility to later misleading information--a finding termed…

Change detection requires perceptual comparison and decision processes on different features of multiattribute objects. How relative salience between two feature-changes influences the processes has not been addressed. This study used the systems factorial technology to investigate the processes when detecting changes in a Gabor patch with visual…

Eyewitnesses sometimes view more than one lineup during an investigation. We investigated the effects of postidentification feedback following one lineup on responses to a second lineup. Witnesses (N = 621) viewed a mock crime and, later, attempted to identify the culprit from an initial (target-absent) lineup and a second (target-present or…

This study furthers the understanding of the connections between learning approaches and learning. The research population embraced 44 males from the Jewish ultraorthodox community, who abide by distinct methods of study. One group follows the very didactic, linear and structured approach of a methodical and gradual order, while the second group…

In this article a continuous-time stochastic model (the Ornstein-Uhlenbeck process) is presented to model the perpetually altering states of the core affect, which is a 2-dimensional concept underlying all our affective experiences. The process model that we propose can account for the temporal changes in core affect on the latent level. The key…

In 4 experiments, we investigated the effects of object affordance in reach-to-grasp actions. Participants indicated whether a depicted small or large object was natural or manmade by means of different object-grasping responses (i.e., with a power or a precision grip). We observed that the size of the depicted object affected the grasping…

This study examines how graduate teaching assistants of composition and peer and professional tutors of writing develop their identities as teacher and tutors in preparation programs. Research in teacher education programs indicates that when preparatory sessions highlight the concept of teacher identity in the preparation of K-12 teacher…

Every day, tens of thousands of chemists use analytical atomic spectroscopy in their work, often without knowledge of possible interferences. We present a unique approach to study these interferences by using modern response surface methods to visualize an interference in which aluminum depresses the calcium atomic absorption signal. Calcium…

The goal of this research project is to investigate whether the use of a personal response system ("clickers") in the classroom increases student participation and discussion and its impact on the quality of the discussion in undergraduate accounting courses. While many studies conducted regarding the use of clickers rely on student…

The colourful, vigorous territorial display behaviour of the Siamese fighting fish, "Betta splendens", has great appeal for both pet enthusiasts and animal behaviourists. Their beauty, longevity, easy maintenance and rearing make them a popular pet and an ideal science laboratory specimen. This investigation utilises "B. splendens" to test for the…
