Decrement in distress to an aversive event during a conditioned positive opponent-process

During Phase 1, 24 rats received CS₁ (light)-shock trials while the remaining 24 rats received CS₁ and shock on a random control schedule. During Phase 2, all subjects were presented trials of CS₂ (tone)-shock. When CS₂ was subsequently presented immediately after CS, while subjects licked for water, it was found that subjects that had received CS₁-shock pairings during Phase 1 exhibited less suppression of licking to CS₂, indicating less distress, than control subjects. The results are compatible with the opponent-process theory and suggest the presence of a positive hedonic afterreaction to an aversive event which reduced distress to a following aversive event.     

Physiological studies of the brain: Implications for science teaching

Physiological changes resulting from repeated, long-term stimulation have been observed in the brains of both humans and laboratory animals. It may be speculated that these changes are related to short-term and long-term memory processes. A physiologically based model for memory processing (PBMMP) can serve to explain the interrelations of various areas of the brain as they process new stimuli and recall past events. The model can also serve to explain many current principles of learning theory and serve as a foundation for developing new theories of learning based upon the physiology of the brain.     

Exploring the complex interplay of national learning and teaching policy and academic development practice

Academic developers are important interpreters of policy, yet little research has focussed on the interplay of policy and academic development practice. Using methods from critical discourse analysis, this article analyses a national learning and teaching policy, charts its development, and explores its interpretation by the academic development community. The findings suggest that while developers played a strategic role in the policy’s development nationally, their influence on and use of policy institutionally was more limited. The article calls on developers to take a more overt leadership role in an area of higher education practice where they clearly have (often unharnessed) expertise.     

Skills Diagnosis Using IRT-Based Continuous Latent Trait Models

This article summarizes the continuous latent trait IRT approach to skills diagnosis as particularized by a representative variety of continuous latent trait models using item response functions (IRFs). First, several basic IRT-based continuous latent trait approaches are presented in some detail. Then a brief summary of estimation, model checking, and assessment scoring aspects are discussed. Finally, the University of California at Berkeley multidimensional Rasch-model-grounded SEPUP middle school science-focused embedded assessment project is briefly described as one significant illustrative application.     

The nominal passover effect depends on addressee age, speaker goal, and object similarity

If after teaching a label for 1 object, a speaker does not name a nearby object, 3-year-olds tend to reject the label for the nearby object (W.E. Merriman, J.M. Marazita, L.H. Jarvis, J.A. Evey-Burkey, and M. Biggins, 1995a). In Studies 1 (5-year-olds) and 3 (3-year-olds), this effect depended on object similarity. In Study 2, when a speaker used a label without teaching it, 5-year-olds showed no passover effect. 3-year-olds showed none for inanimate objects, but one for animate objects. When extraneous factors that may have promoted animate object individuation were eliminated (Study 3), 3-year-olds showed the effect when a label was taught, but not when it was merely used. Children honor rational restrictions on when the unacceptability of a name can be inferred from its nonoccurrence.     

Towards a Comprehensive Account of Effective Thinking

Due to its strong focus on reasoning and argumentation, critical thinking lacks the breadth required of a comprehensive account of higher order thinking. In particular, critical thinking does not promote reflection on the underlying problems or situations that people think about. This paper reviews various proposed additions to and reorientations of the critical thinking paradigm. It presents a conceptual framework that encompasses the most promising extensions as topics in a broadened account of higher order thinking. This account can be understood as an elaboration of problem solving along two dimensions: Problem types, which are generic thinking situations; and problem solving functions, which are generic thinking tasks. The proposed topic-level account of higher order thinking offers a greatly enlarged view of what should be taught in general thinking skills programs.     

Teaching evolution: Understanding and applying the nature of science

The influence of a 3-week institute upon secondary biology and earth science teachers regarding their experiences with respect to the teaching of evolution was investigated. The institute directors, with National Science Foundation (NSF) funding, hoped to foster an understanding of the nature of science, provide enhanced content, and support a forum for teachers to discuss problems common to the teaching of evolution. Analysis of data indicated statistically significant increases in participants' acceptance of the theory of evolution and their understanding of both applied evolutionary principles and the applied nature of science. In addition, a significant reduction in participants' perceived anxieties regarding the teaching of evolution was achieved. Further, a qualitative examination of Stages of Concern (SoC) profiles indicated a slight shift by participants toward the use of more student-centered instruction. Finally, data were collected from 9 of the original 19 participants at a voluntary follow-up session, 8 months after the formal institute. Scores from all of the data-collection instruments (with the exception of SoC profiles) exhibited a slight decline. These decreases were not, however, statistically significant. Examination of SoC profiles, however, indicated a much stronger adoption by follow-up participants for the use of student-centered instructional strategies for the teaching of evolution.     

Student outcomes with rotation of teachers in secondary biology

Look carefully at outcomes in the affective domain before exchanging a classroom with a rotating staff for the conventional one teacher design.     

Salience of Emotional Intelligence as a Core Characteristic of Being a Counselor

The authors investigated the association between emotional intelligence and counseling self‐efficacy. Participants were 140 counseling students and practicing counselors who completed the Emotional Judgment Inventory and the Counseling Self‐Estimate Inventory. Emotional intelligence differentiated counselors from noncounselors (Mdn d = .6650) but provided mixed results in differentiating counseling students and counselors. Moreover, the emotional intelligence factors Identifying Own Emotions, Expressing Emotions Adaptively, and Using Emotions in Problem Solving successfully predicted counseling self‐efficacy of both counseling students and practicing counselors (R = .537). Emotional intelligence may be another marker for individuals exploring professional counseling as a career and for improving students' counseling self‐efficacy.
