Anxiolytic-like effect of ejaculation upon frustration

In three experiments, we studied the consequences of ejaculation upon the frustrative or contrast response of male rats exposed to reward downshift situations (i.e., surprising changes from 32% to 4% sucrose solutions). Similar to what has been found after treatment with anxiolytic agents, consummatory suppression was partially reversed by previous ejaculations in a second postshift trial (Experiments 2 and 3), such a result not having been obtained in a first postshift trial (Experiment 1). Moreover, the effect of ejaculations upon males' behavior during a second postshift trial was transitory, disappearing when assessed during the third and fourth postshift trials (Experiment 3). These results are in accordance with both Amsel's (1958, 1992) frustration theory and Flaherty's (1996) multistage hypothesis of successive negative contrast; the diverse factors that are known to modulate contrast effects are considered, including an interpretation of the present data in terms of the anxiolytic-like effect of the ejaculation.     

The Development of Hierarchical Representation of Two-Dimensional Space

Adults represent the location of a point in a 2-dimensional space using 2 independent dimensions. They encode location along these dimensions both at a fine-grained level and categorically. In reporting location, they combine and weight the fine-grained and categorical information. In Experiment 1, we found that children as young as 5 years use the same 2 independent dimensions in fine-grained spatial coding of location in a circle as are used by adults—radius and angle. However, categorical coding and hierarchical combination are seen only for radius, at both 5 and 7 years. The adult pattern, where angle as well as radius is coded hierarchically, emerges by 9 years. Experiment 2 shows that there is nothing intrinsically difficult about the categorical coding of angular information; when angle is the only dimension to be encoded, younger children use hierarchical coding. Changes in 2-dimensional hierarchical coding may be due to cognitive load factors and to changes in ability to assign frames of reference.     

Simulation research and design: a dual-level framework for multi-project research programs

Collaborations between researchers and practitioners have recently become increasingly popular in education, and educational design research (EDR) may benefit greatly from investigating such partnerships. One important domain in which EDR on collaborations between researchers and practitioners can be applied is research on simulation-based learning. However, frameworks describing both research and design processes in research programs on simulation-based learning are currently lacking. The framework proposed in this paper addresses this research gap. It is derived from theory and delineates levels, phases, activities, roles, and products of research programs to develop simulations as complex scientific artifacts for research purposes. This dual-level framework applies to research programs with a research committee and multiple subordinate research projects. The proposed framework is illustrated by examples from the actual research and design process of an interdisciplinary research program investigating the facilitation of diagnostic competences through instructional support in simulations. On a theoretical level, the framework contributes primarily to the literature of EDR by offering a unique dual-level perspective. Moreover, on a practical level, the framework may help by providing recommendations to guide the research and design process in research programs.

     

Students' perceptions of women and men as learners in higher education

The purpose of this study was to investigate differences in women and men's classroom behavior from the perspective of both traditional college-age and adult students in higher education. A sample of 358 students in four institutions responded to a questionnaire with 39 classroom behaviors. Factor analysis of the survey responses yielded seven dimensions of perceived classroom behavior. Perceptions of male and female behavior differed significantly on six of the seven factors. Perceived differences did not conform entirely to the findings of other research. Gender and age of respondent were related to perceptions of behavior.     

Active Learning in Engineering Education: a (re)introduction

ABSTRACT

The informal network ‘Active Learning in Engineering Education’ (ALE) has been promoting Active Learning since 2001. ALE creates opportunity for practitioners and researchers of engineering education to collaboratively learn how to foster learning of engineering students. The activities in ALE are centred on the vision that learners construct their knowledge based on meaningful activities and knowledge. In 2014, the steering committee of the ALE network reinforced the need to discuss the meaning of Active Learning and that was the base for this proposal for a special issue. More than 40 submissions were reviewed by the European Journal of Engineering Education community and this theme issue ended up with eight contributions, which are different both in their research and Active Learning approaches. These different Active Learning approaches are aligned with the different approaches that can be increasingly found in indexed journals.     

Incorporating Social Justice in Reference Education

Students of reference service can better prepare for careers in serving today’s communities by not only being sensitive to the needs of all members of their communities but also serving as advocates for services for those who are disenfranchised. This column addresses the place of incorporating the philosophy and application of social justice into the education of information specialists who are preparing for careers as reference librarians.     

What makes a word difficult? Insights into the mental representation of technical terms

Learning from texts requires reflection on how far one has mastered the material. Learners use such metacognitive processes to decide whether to engage in deeper learning activities or not. This article examines how the lexical surface of specialist concepts influences their mental representation. Lexical encodings that are the concise wordings of a concept (e.g., tension headache or migraine for specific types of headache) provide immediate access to the underlying content. To understand learning contents appropriately, learners have to work on such lexical covers to gain insight into the underlying semantic meaning. It was assumed that a technical term??s origin (either German or classical Latin/Greek) is used systematically as a hint for further elaboration. 41 college students rated the difficulty, familiarity, competence, accessibility, and their knowledge of 17 German-language (GL) terms and their classical language (CL) synonyms. The influence of word frequency was controlled. As expected, results showed that GL terms were perceived to be less difficult than CL terms. Consequently, comprehension of these terms was rated more highly. Analyses of how lexical encoding influenced accuracy of participants?? comprehension judgments showed that participants?? comprehension ratings were less accurate for GL terms. Theoretical and practical implications for learning from written information are discussed.     

Inclusive Education for Students with Hearing Impairment in the Regular Secondary Schools in the North-West Region of Cameroon: Initiatives and Challenges

Although some initiatives are implemented in the education of students with hearing impairments in the regular school, challenges are still encountered in their education. This article which is part of the results from an ongoing qualitative study in the North-West region of Cameroon addresses the different initiatives and challenges involved with including students with hearing impairment in regular schools. Interviews, participant observations as well as field notes were the main instruments used in collecting data from the six teachers and six students with hearing impairments who participated in the research. Academic support, classroom placement and the way of working of the sign language interpreters were considered the major initiatives and challenges in the education of the students with hearing impairment in regular schools. It is apparent that adequate adjustments have not been made within the schools to meet the needs of the students with hearing impairments. This hence questions their actual inclusion in the regular school.
