Self-punitive avoidance behavior in the mouse

Mice were trained to avoid shock by leaving a startbox and traversing a straight alley. During the first extinction phase (Phase I), two groups were given 30 regular extinction (RE) trials, while another two received punished extinction (PE) trials in the center of the alley. During the last 50 extinction trials (Phase II), conditions were reversed for one of the two groups receiving the same treatment in Phase I. This resulted in two nonshifted groups (RE-RE and PE-PE) and two shifted groups (RE-PE and PE-RE). PE treatment led to higher running speed in both phases and reversed an extinction trend. Furthermore, punishment-induced facilitation was greater for the group receiving PE following RE than for the group receiving PE immediately after avoidance training.

     

The performance of minority students beyond the freshman year: Testing a “late-bloomer” hypothesis in one state university setting

This study examines the validity of standard admissions variables for predicting the long-term performance of minority and nonminority students in one state university. Special attention is given to what may be termed a late-bloomer hypothesis, according to which minority students may be expected to show relatively greater improvement in performance following the freshman year than their nonminority classmates. This hypothesis derives from the plausible argument that minority students face unique problems of adjustment to college which adversely affect their first-year but not their long-term performance. The predictive validity of admissions variables was found to be higher for minority than for nonminority students regardless of the criterion under consideration, and somewhat higher for longer-term cumulative GPA than for shorter-term GPA. Minority and nonminority students were more sharply differentiated by overall cumulative undergraduate GPA than by first-year GPA, inconsistent with the late-bloomer hypothesis.     

China's cooperation in education and training with Kenya: A different model?

This is the first detailed study of the character and particularity of China's rapidly growing education and training cooperation with Kenya. Set against the 50-year history of Kenya's engagement with China, it pays special attention to the human resources targets of the Forum for China–Africa Cooperation (FOCAC) from 2000. It argues that the growing popularity of China as a destination for both short- and long-term training for Kenyans, and the increasing interest by Kenyans in learning Chinese, cannot be separated from the wider involvement of China in Kenya's infrastructure development, the growth of Chinese business and foreign direct investment, and Chinese migration to East Africa.

Robots in the AI Classroom: What Smart Machines Can Teach Smart Students

The design and implementation of autonomous robots provides experience with engineering problems as well as with hard problems in artificial intelligence. Our aims in this article are fourfold: First, we describe how the use of robots complements traditional classroom lectures for the teaching of important concepts in a graduate‐level AI class. Second, we discuss the use of robots as a multimedia tool for capturing student interest and facilitating the self‐guided exploration of AI concepts. Third, we relate readings and robots in the curriculum and show how the robots aid understanding of philosophical issues in AI. Finally, we describe the robot kits and the organization of the class, present several completed projects by student teams, and report some of the feedback given by students who completed the course. We also analyze the successes and failures of the first two courses offered and describe the changes made for the recently completed second course.     

On the role of discipline-related self-concept in deep and surface approaches to learning among university students

The current research examined the role that students’ discipline-related self-concepts may play in their deep and surface approaches to learning, their overall learning outcomes, and continued engagement in the discipline itself. Using a cross-lagged panel design of first-year university psychology students, a causal path was observed in which students’ Semester 1 deep approach to learning positively predicted their Semester 2 psychology-student social identification; this relationship was mediated by students’ actual Semester 1 learning. Moreover, relatively high levels of Semester 2 psychology-student social identification led to a desire for further engagement in the discipline through an enhanced intent to continue their psychology studies. In contrast, discipline-related self-concept was not observed to act as a precursor to learning approaches. Overall, the current data provide clear evidence not only for the validity of the deep learning approach construct, but for the theoretical claims associating a deep learning approach with an impact on self-concept, and the educational value of encouraging a deep learning approach both for short-term academic performance and for continuing motivation to engage in the discipline.     

Toward instituting a chaperone policy in outpatient pediatric clinics

ObjectivesWe sought to evaluate child, parent and medical provider preferences for chaperones for outpatient encounters and to evaluate the acceptability and frequency of utilization following institution of a chaperone policy. Secondarily, we sought to understand what medical history and examinations teens consider “sensitive.”DesignWe conducted an observational study 1 month before and 1 month after institution of outpatient clinic chaperone policy. Post clinic questionnaires were used for patients ≥12 years old, parents, and clinicians. A research assistant observed chaperone use.SettingAdolescent Medicine, Urology, and Rehabilitation Clinics at a regional, tertiary-care pediatric hospital, in a major metropolitan area were studied.ParticipantsConvenience sample: 117 clinic patients during control period and 119 after policy implementation.Main outcome measuresPreferences for and satisfaction with chaperone use were documented.ResultsAlthough non-parent chaperones were usually declined (99.6%), offers were appreciated. Non-parent chaperone use increased modestly (5.3–18.1%).Most patients preferred not to have non-parent chaperones. This preference was greater among older patients (88%), than early teens (52%). After experiencing sensitive examinations, more young adolescent patients (89%) wished their parent had been present than older patients (38%). Patients’ opinions about what constitutes “sensitive” questions and examinations and chaperone preferences varied widely. Providers often did not recognize issues patients and parents considered sensitive questioning (21% agreement), but recognized sensitive physical examinations better (74% agreement). Providers felt chaperones had been a detriment to examination and exams would have gone better without one only 1% of the time.ConclusionsAlthough usually declined, offers of chaperones were appreciated and use of non-parent chaperones increased modestly. Offering chaperones for sensitive examinations may remind providers about appropriate, respectful patient encounters. Implications for children's hospitals’ patient safety and satisfaction, and institutional staff protection and costs are significant.Practice implicationsQuestions and examinations which patients consider sensitive vary widely. Asking patients for their preferences for examination chaperones may reassure them about the appropriateness of examinations, remind staff to conduct respectful examinations and protect providers from accusations of impropriety. Since most chaperone offers are declined, the cost of asking is likely to be minimal.     

De la evaluación informal a la evaluación fundamentada: Reconocer el rol del enseñante en clase

Si las evaluaciones realizadas por los educadores directamente implicados están sujetas a limitaciones y errores, las evaluaciones “formales” y externas presentan también graves, aunque distintas insuficiencias. El autor propone desde ahí nuevas estrategias, métodos, condiciones a cumplir para que la evaluación basada en el educador pueda ser un instrumento potente. Wolf examina estrategias que ayudan a los enseñantes a que la evaluación cotidiana sea más significativa y creíble.     

Impediments to change: Applications of coaching in high-school science teaching

This article describes how two coaching models were utilized in an attempt to assist Jonathon, an experienced teacher who had been teaching science for only two years, to improve his science teaching. Because of the numerous difficulties that Jonathon encountered in planning and implementing the science curriculum, school administrators requested assistance from several science educators from a university near the school. In order to assist Jonathon, two coaching models were used over a period of approximately six months. In the first coaching program two high-school teachers were coached by three science educators from the university. In the second coaching program the teachers coached one another. Neither program was successful in improving Jonathon's teaching in the intended manner. The major impediments to change were Jonathon's beliefs about teaching and learning and his relatively poor knowledge of the science content he was to teach. The findings of the study suggest that the coaching interventions require teachers to analyze teaching, reflect on practice, and consider alternative approaches to teaching and learning. Involvement in the coaching programs provided Jonathon with a foundation of knowledge on which sustained improvements in teaching might develop in the future.
