Pigeons were trained on a discrete-trial delayed reinforcement procedure with respect to one response key that was periodically illuminated. In some conditions, a second response key, or a tone, both previously paired with reinforcement, was interpolated in the delay-of-reinforcement interval. In comparison to a control condition with neither stimulus in the delay interval, the interpolated stimulus attenuated (blocked) the amount of responding that was maintained by the delayed reinforcement contingency. The degree of blocking was unaffected by whether the interpolated stimulus was the tone or keylight, in spite of the fact that the keylight evoked responding and the tone did not. A second study showed that the blocking effects involved the response-reinforcer association in that blocking occurred when the delayed reinforcement was response-dependent but did not occur when reinforcement was response-independent. The results thus show that response-reinforcer associations are affected by informational variables in the same manner as has been shown for stimulus-reinforcer associations. They also demonstrate that preexisting stimulus-reinforcer associations can block response-reinforcer associations, thus suggesting that both types of association depend upon the same associative process. 相似文献

Community colleges in Tennessee, either directly or indirectly, experienced unprecedented change as a result of Tennessee Promise. The present study explored how student support service administrators at three community colleges responded to organizational change as a result of the Tennessee Promise legislation. Investigators selected community colleges for the multi-site case study because the legislative impact would be actualized by the preparations made to serve incoming Promise recipients. The delivery of orientation services framed organizational change because the service staff facilitate connections and provide information to incoming students. Challenges like a shifting population, ill-equipped infrastructure, inadequate remediation support, heightened interest for social engagement opportunities, misinformation, and unmet fiscal needs left administrators seeking coherence through the change process. Investigators found community college administrators react to change similarly. Administrators acknowledged change as continuous, created a culture of innovation among stakeholders, and were not afraid to fail as responses to the organizational change phenomenon. 相似文献

The authors examined the peer feedback exchanged in 2 supervision groups of counselors‐in‐training (CITs). CITs generated 169 statements grouped into 10 clusters representing 5 regions of peer feedback: counselor focus and engagement, insight‐oriented skills, exploratory skills, therapeutic alliance, and intervention activities. Both positive and corrective peer feedback was exchanged on topics ranging from counselor performance skills to case conceptualization. 相似文献

Following educational reform in Israel, teacher-leaders create and lead professional development communities (PDCs), which are professional learning communities with a focus on in-service professional development and/or improving pedagogical effectiveness. Interviews with 30 teacher-leaders and all four district-level program coordinators revealed that, prior to assuming the role, teacher-leaders developed their professional and leadership skills largely in a self-directed manner. They described their PDCs as cohesive and dedicated, cooperative, involving peer-learning, and as creating a knowledge bank of teaching methods and tools. PDCs enable teachers to advance projects within the school and affect school culture. Principals’ involvement with PDCs varied, with their usually considerable involvement very favorably regarded. This article describes these findings and discusses their implications for the professional development of teachers in the international context. 相似文献
