Teacher Education for Effective Science Instruction — A Social Cognitive Perspective

Abstract: Science education suffers from teachers' inadequate preparation and negative attitudes. Social cognitive theory offers teacher educators a model for understanding the reasons for inadequate science instruction and for developing teacher education practices that can overcome the obstacles to effective science instruction. Research showing the relationship between teachers' self-efficacy, anxiety, and teaching effectiveness is reviewed. Teacher education strategies that increase self-efficacy, lower anxiety, and increase teacher effectiveness are described, and problems in science education in need of further study are discussed.

Outlier detection and time series modeling

Abstract: Some statistics used in regression analysis are considered for detection of outliers in time series. Approximations and asymptotic distributions of these statistics are considered. A method is proposed for distinguishing an observational outlier from an innovational one. A four-step procedure for modeling time series in the presence of outliers is also proposed, and an example is presented to illustrate the methodology.

Effects of morphine and naloxone on play-rewarded spatial discrimination in juvenile rats

Abstract: Juvenile rats were trained on a spatial discrimination task (T-maze) rewarded by the opportunity to play with a conspecific. Neither morphine (MS; 1 mg/kg) nor naloxone (NX; 1 mg/kg) administration affected choice or running time during the acquisition of the task, even though in the goal box, MS-treated animals played more than and NX-treated animals less than vehicle-treated controls. Thus, brain opioid systems seem to influence the expression of play without affecting the apparent appetitive strength of play motivation. When play reward was no longer available in the goal box, animals that continued to be treated with MS were more resistant to extinction than either vehicle- or NX-treated animals. They continued to complete the task more often and in less time than the controls. NX-treated rats, on the other hand, extinguished faster than controls. The evidence supports the conclusion that opioid systems are important in the maintenance of social habits.
