‘Brown Paper Packages’? A Sociocultural Perspective on Young Children's Ideas in Science     

Jill Robbins 《Research in Science Education》2005,35(2-3):151-172

How do we see young children's thinking in science? Is it, as much previous research has led us to believe, that their ideas can be neatly boxed like “brown paper packages tied up with strings” – as the song from The Sound of Music goes? Or are their ideas like “wild geese that fly with the moon on their wings” (Sound of Music): fluid, complex, rich.?.?.? Drawing on the author's research into young children's ideas about natural phenomena such as the rain and clouds, and on Rogoff's three foci of analysis (personal, interpersonal and contextual), this paper illustrates how a consideration of sociocultural theory can be useful in framing research with young children, and allow us to see beyond the boxes. Emphasis is placed on recognising that children's thinking in science is embedded within particular sociocultural contexts, is guided by others and integrated with their use of certain mental and physical cultural tools. Thus, the article aims to present an alternative method for the generation of data on young children's thinking. Specific analysis of this data will, it is intended, be presented in a subsequent article.  相似文献   

Exit cards: creating a dialogue for continuous evaluation     

Mazna Patka  Jennifer Wallin-Ruschman  Tenille Wallace  Candice Robbins 《Teaching in Higher Education》2016,21(6):659-668

This study explored the use of Exit Cards, which are formative evaluations of student knowledge and instruction undertaken at every class meeting. Its results are based on Exit Card data from two undergraduate research methods courses. Thematic analysis indicated that students used Exit Cards to communicate (1) what they learned, (2) challenges with course material, (3) experiences with peers, (4) requests for help, (5) challenges with coping, and (6) successes. While the present study is an initial exploration of the use of Exit Cards, it contributes to knowledge on the utilization of informal formative assessments.  相似文献   

The effects of isolation rearing on exploration in the rat     

B. J. Sahakian  T. W. Robbins  S. D. Iversen 《Learning & behavior》1977,5(2):193-198

The hypothesis that isolation rearing enhances exploration was tested in two settings which varied the extent to which exploratory behavior would be affected by competing hyperactivity. Experiment 1 measured exploration as contact of a discrete novel stimulus, in terms of bout frequency and duration. Locomotor activity was measured by photocell beam interruption. Isolation-reared rats were hyperactive, showed an increased incidence of exploratory bouts but no differences in duration of exploratory behavior, compared with group-reared controls. Experiment 2 measured, independently, locomotor activity and the preference for a novel environment over a familiar one. Isolation-reared rats, whether male or female, showed enhanced novelty preference compared with controls. No significant differences were found in locomotor activity. The results are discussed in terms of the hyperactivity of isolates interfering with investigative behavior by response incompatibility.  相似文献   

The role of signaled periods of nonreinforcement in responding on a random schedule in autoshaping     

Steven J. Robbins  Robert A. Rescorla 《Learning & behavior》1989,17(3):304-310

Little responding develops to a conditioned stimulus (CS) that is placed in a random relation to an unconditioned stimulus (US). However, if the USs not preceded by that CS are themselves signaled by another stimulus, then the CS does come to elicit responding. This result has been attributed (e.g., by Durlach, 1983) to the signal’s blocking of conditioning to background cues that otherwise would prevent conditioning of the CS. However, Goddard and Jenkins (1987) have suggested the alternative that signaling the USs promotes responding due to the adventitious creation of periods of signaled nonreinforcement. Two experiments were conducted to assess this alternative, involving an autoshaping preparation in pigeons. In Experiment 1, little responding to a keylight CS presented in a random relation to a food US occurred, despite the explicit presentation of a discrete noise signaling periods of no food in the intertrial interval (ITI). Experiment 2 was designed to replicate the procedure of Goddard and Jenkins, in which an auditory stimulus extended throughout the ITI of a random schedule, terminating only prior to extra USs and during the CS. Contrary to their findings, little responding developed to the target CS. However, responding did develop when the sound-free period occurred only prior to the extra USs. These results offer little support for the hypothesis that signaled periods of nonreinforcement promote responding on random schedules. However, they are consistent with the view that signaling of ITI USs acts by preventing conditioning of potentially competitive background cues.  相似文献   

A Multipart Project Planning and Tracking Exercise     

Thomas R. Robbins 《Decision Sciences Journal of Innovative Education》2019,17(2):104-125

Project Management is an important skill for business students to develop. Although project‐oriented activity is very common, the success rate for projects is poor. Many projects fail due to poor planning. This article describes a multipart class exercise used to teach elements of a project management methodology to undergraduate and graduate business students. Over the course of the eight‐part exercise, student teams iteratively develop a project plan and Gantt chart, an initial and detailed project charter, a variance analysis model, and a status report. Students are taught an iterative top‐down planning process using a technique we term the ODW (Objectives–Deliverables–Workplan) model. Students are introduced to Microsoft Project and use the tool to develop a project plan that becomes part of a more detailed Project Charter. In the final stages of the exercise, students collect results, update their plan, and produce a project status report.  相似文献

Skating start propulsion: three-dimensional kinematic analysis of elite male and female ice hockey players     

Jaymee R. Shell  Shawn M. K. Robbins  Philippe C. Dixon  Philippe J. Renaud  René A. Turcotte  Tom Wu 《Sports biomechanics / International Society of Biomechanics in Sports》2017,16(3):313-324

The forward skating start is a fundamental skill for male and female ice hockey players. However, performance differences by athlete’s sex cannot be fully explained by physiological variables; hence, other factors such as skating technique warrant examination. Therefore, the purpose of this study was to evaluate the body movement kinematics of ice hockey skating starts between elite male and female ice hockey participants. Male (n = 9) and female (n = 10) elite ice hockey players performed five forward skating start accelerations. An 18-camera motion capture system placed on the arena ice surface captured full-body kinematics during the first seven skating start steps within 15 meters. Males’ maximum skating speeds were greater than females. Skating technique sex differences were noted: in particular, females presented ~10° lower hip abduction throughout skating stance as well as ~10° greater knee extension at initial ice stance contact, conspicuously followed by a brief cessation in knee extension at the moment of ice contact, not evident in male skaters. Further study is warranted to explain why these skating technique differences exist in relation to factors such as differences in training, equipment, performance level, and anthropometrics.  相似文献
