Sketching is widely used in design to generate creative ideas. Design studies present stimuli during sketching to enhance creativity. This study examines the effect of stimuli presented during different sketching states, especially of those presented during the stuck period. It conducted a sketching experiment that enrolled 41 students with an…

The research field of intuitive physics focuses on discrepancies between theoretical and intuitive physical knowledge. Consideration of these discrepancies can help in the teaching of elementary physics. However, evidence shows that theoretical and intuitive physical knowledge may also be congruent. Physics teaching could further benefit from…

Although there is consistent evidence that higher levels of processing, such as learning the form-meaning associations specific to the second language (L2), are a source of difficulty in acquiring L2 speech, no study has addressed how these levels interact in shaping L2 perception and production of intonation. We examine the hypothesis of whether…

Protein synthesis is involved in the consolidation of short-term memory into long-term memory. Previous electrophysiological data concerning LTP in CA3 suggest that protein synthesis in that region might also be necessary for short-term memory. We tested this hypothesis by locally injecting the protein synthesis inhibitor anisomycin in hippocampal…

Our aim in this article is to elaborate the role of training in representational change theory (RCT), particularly in terms of Ohlsson's (2011) spread of activation explanation (named "redistribution theory"), and to develop novel training manipulations that effect the re-encoding mechanism proposed by RCT (Ohlsson, 1992). Two…

The Accreditation role of the National Universities Commission (NUC) and the quality of the educational inputs into Nigerian university system was investigated in this work, using a descriptive research of survey design. The population consisted of public Universities in South-West, Nigeria. The sample was made up of 300 subjects, consisting of 50…

This article provides validity evidence for a measure of listening goals by showing theoretically consistent relationships with an existing communication preference questionnaire. Participants (N = 257) were administered trait measures for listening goals and communicator preferences. The four listening goals--relational, task-oriented,…

There is substantial variance in the age at which children construct and deploy their first explicit theory of biology. This study tests the hypothesis that this variance is due, at least in part, to individual differences in their executive function (EF) abilities. A group of 79 boys and girls aged 5-7 years (with a mean age of 6½ years) were…

Could the same interests that draw many students to psychology also predict departure from the major? I present a comparison of students and instructors with respect to professional interests and views of the scientific nature of psychology (Study 1) and an examination of the link between student interests and persistence in the major (Study 2).…

Applications of multilevel models to continuous outcomes nearly always assume constant residual variance and constant random effects variances and covariances. However, modeling heterogeneity of variance can prove a useful indicator of model misspecification, and in some educational and behavioral studies, it may even be of direct substantive…

The AAAS Vision and Change report (2011) recommends incorporating student research experiences into the biology curriculum at the undergraduate level. This article describes, in detail, how "Zea mays" (corn) cultivars were used as a model for a hypothesis-driven short-term research project in an introductory biology course at a small…

This article examines if and how characteristics of appraisal systems used for secondary school teachers affect job satisfaction. Using multilevel analyses on data of 3 473 teachers in Flanders (Belgium), we found that appraisals with a developmental purpose and appraisals perceived as being a fair judgement, both have a positive impact on job…

High rates of Information Technology (IT) project failures continues; fail to meet established deadlines, exceeding budget, or not agreed-upon functionality. Failure often results from a fundamental confusion over what is involved in the project. Methods that have provided project success in Service and Manufacturing industries have not been…

A multiple testing method for examining factorial invariance for latent constructs evaluated by multiple indicators in distinct populations is outlined. The procedure is based on the false discovery rate concept and multiple individual restriction tests and resolves general limitations of a popular factorial invariance testing approach. The…

Research methods is perceived as a technical and difficult topic by some students. Using role-play to teach it can make it more accessible, meaningful and engaging. Role-playing the familiar roles of customer and waiting staff at a restaurant and discussing the variables that may affect the size of tips can help students to learn some of the key…
