Personal,professional, political: an exploration of science teacher identity development for teaching climate change     

Andrea Drewes 《Environmental Education Research》2020,26(4):611-612

Abstract

Climate change presents societal and environmental challenges, as well as educational ones. Obstacles abound within teaching and learning climate change, related to its complex nature, the proliferation of misinformation, and its absence from many science curricula. Efforts have previously been made to study teacher content knowledge and beliefs on climate change with varying results. This study employed identity as a theoretical framework to examine aspects of climate change teaching. This study followed a reflexively iterative process that enabled the construction of a conceptual model for identity development. This model demonstrates multifaceted influences including personal, professional, and political elements, and the dynamism these elements exhibit over time. This conceptual model is best described via five trends: Personal Valuation of Nature; Experiences in Science Teaching and Learning; Teacher Instructional Support and Agency; Epistemic Evidence-based Instruction; and Civic and Social Awareness via Socioscientific Literacy. The presence and strength of enactment of each trend led to the development of four possible constructions of identity: Passionate Environmentalist, Student Interest Engager, Content First Educator, and Civic and Epistemic Skills Promoter. Most frequently teachers exhibited combinations of identities and often created a unique amalgam of multiple dimensions of identities in action.  相似文献   

A Model of School Counseling Supervision: The Goals,Functions, Roles,and Systems Model     

Chris Wood  Andrea Dixon Rayle 《Counselor Education & Supervision》2006,45(4):253-266

The authors outline the Goals, Functions, Roles, and Systems Model (GFRS), a school counseling—specific model for supervising school counselors‐in‐training (SCITs). The GFRS was created as a guide for assisting in supervising and preparing SCITs for the multifaceted tasks they will undertake in their internships and careers. The components of this model are described within the context of the systems influencing supervision of SCITs. The GFRS is detailed to illustrate how it meets the specific needs of school counseling supervision. Examples are included of the GFRS when applied in supervision.  相似文献

Computer science and engineering: utilizing action research and lesson study     

Andrea C. Burrows  Mike Borowczak 《Educational Action Research》2019,27(4):631-646

ABSTRACT

This article explores one group’s use of action research (AR) and lesson study in three US university-level computer science courses affecting 85 undergraduate computer science and engineering students. It offers an overview of three areas including AR, lesson study, and engineering soft skills. The research group identified a problem: undergraduate engineering student soft skill understanding. The group collaborated to enhance participant engagement with this problem by utilizing one lesson focused on soft skills over three research lesson iterations in three distinct university semesters (2017-2018). Field notes were the main data collection method. Observational field notes were recorded in the three research lesson iterations, and themes from the notes were identified. The group valued peer interactions, and the research lesson adaptations as well as pedagogical changes were based on evidence. Four themes were identified, and participant comments were considered as the lessons became more focused . The research group argues that AR and lesson study are separate and distinct ventures based on this yearlong experience, which is counter to some other literature presented. Implications are large for all stakeholders interested in AR, lesson study, soft skill utilization, conflict management, and participant learning impact. Possibilities for enhanced participant engagement exists with honed lesson pedagogy.  相似文献   

Response rate is not an effective mediator of learned stimulus equivalence in pigeons     

Frank AJ  Wasserman EA 《Learning & behavior》2005,33(3):287-295

We explored response rate as a possible mediator of learned stimulus equivalence. Five pigeons were trained to discriminate four clip art pictures presented during a 10-sec discrete-trial fixed interval (FI) schedule: two paired with a one-pellet reinforcer, which supported a low rate of responding, and two paired with a nine-pellet reinforcer, which supported a high rate of responding. After subjects associated one stimulus from each of these pairs with a discriminative choice response, researchers presented two new clip art stimuli during a 10-sec FI: one trained with a differential reinforcement of low rate schedule (DRL) after the FI and the other trained with a differential reinforcement of high rate schedule (DRH) after the FI. Each of the stimuli that were withheld during choice training was later shown to see if the choice responses would transfer to these stimuli. The results suggest that response rate alone does not mediate learned stimulus equivalence.  相似文献   

Food sharing in albino rat pups: Does familiarity breed contempt?     

Georgia D. Wills  Frank R. Moore  Andrea L. Wesley  Barry Friedman 《Learning & behavior》1984,12(1):106-108

The present experiment investigated the effects of kinship and familiarity upon food sharing in pairs of albino rat pups. Five pairs of rats from each of the following groups were tested: (1) familiar siblings, (2) nonfamiliar siblings, (3) familiar nonsiblings, and (4) nonfamiliar non-siblings. A small food portion was used, necessitating not only close physical contact, but also cooperation in the sense that both pups were required to remain relatively immobile in order for both to feed simultaneously. Results indicated more frequent sharing among unfamiliar pups, whether related or not. Results also indicated that food sharing increased in frequency among all four groups over the 5-day testing period, suggesting that cooperation in the form of food sharing can develop, or increase in frequency, over time in albino rat pups.  相似文献

Reinstatement-induced recovery of a taste-LiCl association following extinction     

Todd R. Schachtman  Andrea M. Brown  Ralph R. Miller 《Learning & behavior》1985,13(3):223-227

Water-deprived rats were given a single exposure to saccharin and LiCl, either paired or unpaired. Half the subjects then received three saccharin-only exposures (extinction) in the training enclosure, followed by a single LiCl-only presentation (unconditioned stimulus reinstatement) 8 days after conditioning. The remaining subjects received six saccharin-only exposures, followed by LiCl reinstatement 13 days after conditioning. In both cases LiCl reinstatement occurred outside the training/test context. Appreciable recovery from extinction was observed after the partial loss of taste aversion obtained with three extinction sessions and the 8-day conditioning-reinstatement interval, but not after the asymptotic loss of taste aversion obtained with six extinction sessions and the 13-day conditioning-reinstatement interval. Conditioned taste aversions appear to be similar to more traditional associations with respect to both extinction and reinstatement-induced recovery from extinction. The results are discussed with reference to the event-memory, contextual-conditioning, and facilitated-retrieval hypotheses of postextinction reinstatement effects.  相似文献   

Enhancing the effectiveness of concept inventories using textual analysis: investigations in an electrical engineering subject     

Andrea M. Goncher  Wageeh Boles 《European Journal of Engineering Education》2019,44(1-2):222-233

ABSTRACT

Concept inventories (CIs) are assessment instruments designed to measure students’ conceptual understanding of fundamental concepts in particular fields. CIs utilise multiple-choice questions (MCQs), and specifically designed response selections, to help identify misconceptions. One shortcoming of this assessment instrument is that it fails to provide evidence of the causes of the misconceptions, or the nature of students’ conceptual understanding. In this article, we present the results of conducting textual analysis on students’ written explanations in order to provide better judgements into their conceptual understanding. We compared students’ MCQ scores in Signals and Systems Concept Inventory questions, with the textual analysis utilising vector analysis approaches. Our analysis of the textual data provided the ability to detect answers that students identified as a ‘guessed’ response. However, the analysis was unable to detect if conceptually correct ideas existed within the ‘guessed’ responses. The presented approach can be used as a framework to analyse assessment instruments that utilise textual, short-answer responses. This analysis framework is best suited for the restricted conditions imposed by the short-answer structure.  相似文献
