Museums and the shaping of contemporary artworks     

Sherri Irvin Author Vitae 《Museum Management and Curatorship》2006,21(2):143-156

In the museum context, curators and conservators often play a role in shaping the nature of contemporary artworks. Before, during and after the acquisition of an art object, curators and conservators engage in dialogue with the artist about how the object should be exhibited and conserved. As a part of this dialogue, the artist may express specifications for the display and conservation of the object, thereby fixing characteristics of the artwork that were previously left open. This process can make a significant difference to the visual appearance of the work, the nature of the audience's experience, and how the work should be interpreted. I present several case studies in which the nature of the artwork has been shaped by such dialogues, and discuss principles for resolving cases in which there is a conflict between instructions specified by the artist and those adopted by the museum.  相似文献

Predicting Parent-Child Differences in Perceptions of How Children Use the Internet for Help With Homework,Identity Development,and Health Information     

Sherri Jean Katz  Theodore Lee  Sahara Byrne 《广播与电子媒介杂志》2015,59(4):574-602

Bioecological systems theory provides a framework to understand how factors in the child's environment contribute to parent-child differences in estimations of how often children are helped by their Internet use. A national sample survey of 456 matched parent-child pairs investigated how parents-child relational factors, parental attitudes toward the Internet, and the bio-ecology of the child, are related to differing perceptions of the frequency of using the Internet to seek help with homework assignments, to aid in identity development, and to find health information. While previous research shows that parents underestimate risky online behaviors, we investigate whether parent-child differences will emerge in regards to how often the child engages in the behaviors under investigation here. The findings show that parents overestimate these online activities, suggesting they are biased in their estimations. Parent-child relational factors emerged as predictors of parental overestimation for each of these online activities, with trust perceptions as the most consistent predictor. Parental attitudes toward the Internet predicted parent-child differences in perceptions of how frequently the child used the Internet for help with homework and identity development, while the bioecology of the child was only predictive in the case of using the Internet for help with homework.  相似文献   

Unpacking foreshadowing in mathematics teachers’ planned practices     

Wasserman  Nicholas H. 《Educational Studies in Mathematics》2022,111(3):423-443

This paper provides an empirical exploration of mathematics teachers’ planned practices. Specifically, it explores the practice of foreshadowing, which was one of Wasserman’s (2015) four mathematical teaching practices. The study analyzed n?=?16 lessons that were planned by pairs of highly qualified and experienced secondary mathematics teachers, as well as the dialogue that transpired, to identify the considerations the teachers made during this planning process. The paper provides empirical evidence that teachers engage in foreshadowing as they plan lessons, and it exemplifies four ways teachers engaged in this practice: foreshadowing concepts, foreshadowing techniques, foregrounding concepts, and foregrounding techniques. Implications for mathematics teacher education are discussed.

Circulation — The Making of: Library Videos and the Real World     

Sherri Saines 《The Journal of Academic Librarianship》2011,37(6):532-535

The Ohio University Libraries has been a part of the university's Freshman Year Experience (FYE) classes almost since their inception. Over the past ten years, we have tried many variations on the “library day” lesson plan, with various (low) success rates. For fall of 2010, the FYE coordinator asked for an extremely simple plan: just some videos about services and a walk through the library. It was well-timed; we were both frustrated with the low use of our lesson plans and getting better at video production. It seemed it would be so easy … and then, of course it wasn't. We were saved by collaborating with a film student, and one of our videos was awarded an ALA 2011 PR “Best of Show”. Students and instructors respond well to humorous short videos in which we do not take ourselves too seriously.  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   

Preservice Teachers’ Research Experiences in Scientists’ Laboratories     

Sherri Brown  Claudia Melear 《Journal of Science Teacher Education》2007,18(4):573-597

To promote the use of scientific inquiry methods in K-12 classrooms, departments of teacher education must provide science teachers with experiences using such methods. To comply with state and national mandates, an apprenticeship course was designed to afford preservice secondary science teachers opportunities to engage in an authentic, extended, open-ended inquiry. This study describes three teachers’ apprenticeship experiences with a research scientist. Our model included placing preservice teachers with scientists in expert/novice roles where each teacher would be actively engaged in constructing knowledge. From triangulating interview, laboratory notebook, and reflective summary data resources, we identified common themes from re-occurring statements. Findings indicated that participants acquired scientific skills and content knowledge; however, they expressed limited use of these in their classrooms.  相似文献   

Associative structure of second-order conditioning in humans     

Paul Craddock  Jessica S. Wasserman  Cody W. Polack  Thierry Kosinski  Charlotte Renaux  Ralph R. Miller 《Learning & behavior》2018,46(2):171-181

Second-order conditioning (SOC; i.e., conditioned responding to S2 as a result of S1–US pairings followed by S2–S1 pairings) is generally explained by either a direct S2→US association or by an associative chain (i.e., S2→S1→US). Previous research found that differences in responses to S2 after S1 was extinguished often depended on the nature of the S2–S1 pairings (i.e., sequential or simultaneous). In two experiments with human participants, we examined the possibility that such differences result from S1 evoking S2 during extinction of S1 following simultaneous but not sequential S2–S1 pairings. This evocation of S2 by S1 following simultaneous pairings may have paired the evoked representation of S2 with absence of the outcome, thereby facilitating mediated extinction of S2. Using sequential S2-S1 pairings, both Experiments 1 and 2 failed to support this account of how extinction of S1 reduced responding to S2. Experiment 1 found that extinguishing S1 reduced responding to S2, while extinguishing S2 had little effect on responses to S1, although forward evocation of S1 during extinction of S2 paired the evoked representation of S1 with absence of the outcome. In Experiment 2, evocation of S2 during S1 nonreinforced trials was prevented because S2–S1 pairings followed (rather than proceeded) S1-alone exposures. Nevertheless, responding to S2 at test mimicked S1 responding. Responding to S2 was high in the context in which S1 had been reinforced and low in the context in which S1 had been nonreinforced. Collectively, these experiments provide additional support for the associative-chain account of SOC.  相似文献   

Teacher–Child Interactions in Early Head Start Classrooms: Associations With Teacher Characteristics     

Sherri Castle  Amy C. Williamson  Emisha Young  Jessica Stubblefield  Deborah Laurin  Nicole Pearce 《Early education and development》2016,27(2):259-274

ABSTRACT

Research Findings: The current study examined characteristics of 71 Early Head Start lead teachers in relation to classroom interactions with infants and toddlers. Measured teacher characteristics included education, years of experience, beliefs about child rearing, depressive symptoms, and the temperamental characteristics of positivity and frustration. Teacher–child interactions were measured using the Classroom Assessment Scoring System, Toddler Version (La Paro, Hamre, & Pianta, 2012). Results indicated that field of degree was directly associated with the majority of dimensions of teacher–child interactions. Examination of teachers’ years of experience and intrapersonal characteristics revealed a number of significant interactions, indicating that teacher experience and appropriate beliefs may serve as protective factors in the presence of psychosocial risk factors. Practice or Policy: Overall, our findings suggest that both early childhood education degrees and years of experience are directly or indirectly associated with multiple dimensions of teacher–child interactions, confirming that these patterns established for preschool teachers hold for teachers of infants and toddlers. These results also suggest that years of experience and progressive beliefs about children may be especially important for teachers who are depressed or who have low levels of positivity and high levels of frustration. Implications for future research, as well as preservice and in-service professional development, are discussed.  相似文献   

Native American Adolescent Career Development     

Sherri L. Turner  Richard T. Lapan 《Journal of Career Development》2003,30(2):159-172

Within the framework of Social Cognitive Career (SCCT; Lent, Brown, & Hackett, 1994, 2000), this study examined the associations among career interests, career efficacy expectations, gender, and perceived parent support among Native American and Caucasian middle school adolescents. Consistent with previous research, results indicated that Native American young people had greater interests in Realistic and Conventional occupations, and in occupations that typically require a high-school diploma, a trade school certificate, or 2 years of post high-school education. However, contrary to previous findings, they had as great a range of interests in and self-efficacy expectations for Investigative, Artistic, Social, and Enterprising occupations as Caucasian adolescents, and similarly high levels of interests, efficacy, and perceived parent support for careers typically requiring 4 or more years of post-high school education.  相似文献
