Boys are less likely to receive praise and recognition for good schoolwork, to consider school important, and have fewer opportunities to do the things that they do best (Lopez and Calderon in How America’s boys become psychological dropouts. The gallup blog, 2013). Traditional school cultures have come in conflict with the normal and natural ways that boys behave. As a result, boys have had alienating experiences and high levels of disengagement and lowered academic success in school due to rejection of boy culture, which includes aggressive play, competition, and violent fantasy. The purpose of this study was to explore ways in which we can re-engage boys and enhance their learning opportunities in traditional classroom settings. Boys are drawn to video games, which offer a unique environment where they can engage in learning activities. By taking seriously the indigenous knowledge of this portion of boy culture, we may identify ways in which their expertise can become useful towards common learning goals (Carr-Chellman 2007; Carr-Chellman and Savoy 2004). The current analysis represents the first of a multiphase study that uses an interpretive lens within a CHAT framework to identify relevant learning in Commercial of the Shelf (COTS) games. This phenomenological design identifies learning accounts that map to the United States Common Core State Standards. Our findings suggest that engaged learning can occur for these boys as a result of playing games. COTS games engage boys in normal and natural ways, and consequently can be relevant learning tools that educators, researchers and instructional designers might employ toward traditional learning objectives.  相似文献   

Preservice teachers’ use of contrasting cases in mathematics instruction     

Katerina Schenke  Lindsey E. Richland 《Instructional Science》2017,45(3):311-329

Drawing comparisons between students’ alternative solution strategies to a single mathematics problem is a powerful yet challenging instructional practice. We examined 80 preservice teachers’ when asked to design a short lesson when given a problem and two student solutions—one correct and one incorrect. These micro-teaching events were videotaped and coded, revealing that fewer than half of participants (43%) made any explicit comparison or contrasts between the two solution strategies. Those who did were still not likely to use additional support strategies to draw students’ attention to key elements of the comparison. Further, correlations suggest that participants’ mathematical content knowledge may be related to whether participants’ showed contrasting cases but not to whether they used specific pedagogical cues to support those comparisons. While these micro-teaching events differ from the interactive constraints of a classroom, they reveal that participants did not immediately orient toward differing student solutions as a discussion opportunity, and that future instruction on contrasting cases must highlight the utility of this practice.  相似文献

Indigenous cultural contexts for STEM experiences: snow snakes’ impact on students and the community     

Brant G. Miller  Gillian Roehrig 《Cultural Studies of Science Education》2018,13(1):31-58

Opportunities for American Indian youth to meaningfully engage in school-based science, technology, engineering, and mathematics (STEM) experiences have historically been inadequate. As a consequence, American Indian students perform lower on standardized assessments of science education than their peers. In this article we describe the emergence of meaning for students—as well as their community—resulting from Indigenous culturally-based STEM curriculum that used an American Indian tradition as a focal context. Specifically, the game of snow snakes (Gooneginebig in Ojibwe) afforded an opportunity for STEM and culturally-based resources to work in unison. A case study research design was used with the bounded case represented by the community associated with the snow snake project. The research question guiding this study was: What forms of culturally relevant meaning do students and the community form as a result of the snow snake game? Results indicate evidence of increased student and community engagement through culturally-based STEM experiences in the form of active participation and the rejuvenation of a traditional game. Implications are discussed for using culturally-based contexts for STEM learning.  相似文献   

The Talking Drawings Strategy: Using Primary Children’s Illustrations and Oral Language to Improve Comprehension of Expository Text     

Kelli R. Paquette  Susan E. Fello  Mary Renck Jalongo 《Early Childhood Education Journal》2007,35(1):65-73

Listening and reading comprehension can be assessed by analyzing children’s visual, verbal, and written representations of their understandings. “Talking Drawings” (McConnell, S. (1993). Talking drawings: A strategy for assisting learners. Journal of Reading, 36(4), 260–269 is one strategy that enables children to combine their prior knowledge with the new information derived from an expository text and “translate” those newly-acquired understandings into other symbol systems, including an oral discussion with a partner, a more detailed drawing, and written labels for the drawing. The Talking Drawings strategy begins by inviting children to create pre-learning drawings. These initial drawings are a way of taking inventory of a child’s current content knowledge about a particular topic. After pre-learning drawings are created and shared, children listen to or read an expository text (e.g., information book, passage from a textbook) on the same topic as their drawing. Pairs of students discuss the information and either modify their pre-learning drawings to be more detailed or create completely new drawings that reflect the recently-acquired information. Students are encouraged to label their drawings with words in a diagram or schematic fashion. By evaluating the “before” and “after” artwork, educators can identify advances in students’ reading and listening comprehension of the terminology, facts, and principles on a particular topic.  相似文献   

Photoresists for microlithography     

Debmalya Roy  P. K. Basu  S. V. Eswaran 《Resonance》2002,7(7):44-53

Photoresist technology, which is used for micro-patterning exploits changes in properties of polymeric materials, such as their solubility or volatility, upon photo-irradiation. This process has greatly benefitted from the knowledge base of organic chemistry and photo-induced organic transformations. The role of chemistry in the development of photoresists is described in this article.  相似文献   

Response-cost punishment with pigeons: Further evidence of response suppression via token loss     

Raiff BR  Bullock CE  Hackenberg TD 《Learning & behavior》2008,36(1):29-41

Four pigeons responded on a two-component multiple token-reinforcement schedule, in which tokens were produced according to a random-interval 30-sec schedule and exchanged according to a variable-ratio 4 schedule in both components. To assess the effects of contingent token loss, tokens were removed after every second response (i.e., fixed-ratio 2 loss) in one of the components. Response rates were selectively lower in the loss components relative to baseline (no-loss) conditions, as well as to the within-condition no-loss components. Response rates were decreased to a greater degree in the presence of tokens than in their absence. To control for the effects of changes in the density of token and food reinforcement, two parts consisted of additional conditions where food density and token loss were yoked to those in a previous loss condition. In the yoked-food condition, tokens were produced as usual in both components, but the overall density of food reinforcement in one of the components was yoked to that obtained during a previous token-loss condition. In the yoked token-loss condition, tokens were removed during one component of the multiple schedule at a rate that approximately matched the obtained rate of loss from a previous token-loss condition. Response rates in these yoked components were less affected than those in comparable loss components, despite similar densities of token, exchange, and food reinforcement. On the whole, the results support the conclusion that contingent token loss serves as an effective punisher with pigeons.  相似文献

Exploring the Effects of Financial Aid on the Gap in Student Dropout Risks by Income Level   总被引：1，自引：0，他引：1  

Rong Chen  Stephen L. DesJardins 《Research in higher education》2008,49(1):1-18

Using national survey data and discrete-time logit modeling, this research seeks to understand whether student aid mediates the relationship between parental income and student dropout behavior. Our analysis confirms that there is a gap in dropout rates for low-income students compared with their upper income peers, and suggests that some types of aid are associated with lower risks of dropout. Thus, we examine the interaction between financial aid type and parental income to explore whether, and if so how, different types of aid may reduce the dropout gap by income level group. We find that the receipt of a Pell grant is related to narrowing the dropout gap between students from low- and middle-income groups, although overall the interaction between Pell grant and income is not significant. Loans and work-study aid both have similar effects on student dropout across all income groups. Methodologically, our results demonstrate the need to model dropout behavior temporally and to avoid main-effect bias by incorporating interaction effects.

How New Caledonian crows solve novel foraging problems and what it means for cumulative culture     

Corina J. Logan  Alexis J. Breen  Alex H. Taylor  Russell D. Gray  William J. E. Hoppitt 《Learning & behavior》2016,44(1):18-28

New Caledonian crows make and use tools, and tool types vary over geographic landscapes. Social learning may explain the variation in tool design, but it is unknown to what degree social learning accounts for the maintenance of these designs. Indeed, little is known about the mechanisms these crows use to obtain information from others, despite the question’s importance in understanding whether tool behavior is transmitted via social, genetic, or environmental means. For social transmission to account for tool-type variation, copying must utilize a mechanism that is action specific (e.g., pushing left vs. right) as well as context specific (e.g., pushing a particular object vs. any object). To determine whether crows can copy a demonstrator’s actions as well as the contexts in which they occur, we conducted a diffusion experiment using a novel foraging task. We used a nontool task to eliminate any confounds introduced by individual differences in their prior tool experience. Two groups had demonstrators (trained in isolation on different options of a four-option task, including a two-action option) and one group did not. We found that crows socially learn about context: After observers see a demonstrator interact with the task, they are more likely to interact with the same parts of the task. In contrast, observers did not copy the demonstrator’s specific actions. Our results suggest it is unlikely that observing tool-making behavior transmits tool types. We suggest it is possible that tool types are transmitted when crows copy the physical form of the tools they encounter.  相似文献
