Reflection‐Impulsivity in Retarded Adolescents and Non‐retarded Children     

Merrill S. Jackson  Allan T. Haines 《International Journal of Disability, Development & Education》1983,30(3):230-232

This study examined the responses to Kagan's Reflectivity‐Impulsivity test (and its relevance to temptation to steal dilemmas) of mentally retarded and non‐retarded subjects matched for both MA and CA and for sex. Retarded subjects were less reflective than non‐retarded children when matched on the basis of CA but showed no difference when matched on the basis of MA, confirming findings by Borys and Spitz (1978).  相似文献   

Food Fights: Cookbook Rhetorics,Monolithic Constructions of Womanhood,and Field Narratives in Technical Communication     

Marie E. Moeller  Erin A. Frost 《Technical Communication Quarterly》2016,25(1):1-11

Field narratives that (re)classify technical genres as liberating for women risk supporting the notion that feminism is a completed project in technical communication scholarship. This article suggests that technical communicators reexamine the impact of past approaches to critical engagement at the intersections of gender studies and technical communication; cookbooks provide a material example. The authors illustrate how a feminist approach to cookbooks as technical/cultural artifacts can productively revise field narratives in technical communication.  相似文献   

Teachers’ Integration of Scientific and Engineering Practices in Primary Classrooms     

Eileen G. Merritt  Jennie Chiu  Erin Peters-Burton  Randy Bell 《Research in Science Education》2018,48(6):1321-1337

The Next-Generation Science Standards (NGSS) challenge primary teachers and students to work and think like scientists and engineers as they strive to understand complex concepts. Teachers and teacher educators can leverage what is already known about inquiry teaching as they plan instruction to help students meet the new standards. This cross-case analysis of a multiple case study examined teacher practices in the context of a semester-long professional development course for elementary teachers. We reviewed lessons and teacher reflections, examining how kindergarten and first grade teachers incorporated NGSS scientific and engineering practices during inquiry-based instruction. We found that most of the teachers worked with their students on asking questions; planning and carrying out investigations; analyzing and interpreting data, using mathematics and computational thinking; and obtaining, evaluating and communicating information. Teachers faced challenges in supporting students in developing their own questions that could be investigated and using data collection strategies that aligned with students’ development of number sense concepts. Also, some teachers overemphasized the scientific method and lacked clarity in how they elicited and responded to student predictions. Discussion focuses on teacher supports that will be needed as states transition to NGSS.  相似文献   

Fractions as the Coordination of Multiplicatively Related Quantities: A Cross-Sectional Study of Children's Thinking     

Susan B. Empson  Debra Junk  Higinio Dominguez  Erin Turner 《Educational Studies in Mathematics》2006,63(1):1-28

Although equal sharing problems appear to support the development of fractions as multiplicative structures, very little work has examined how children's informal solutions reflect this possibility. The primary goal of this study was to analyze children's coordination of two quantities (number of people sharing and number of things being shared) in their solutions to equal sharing problems and to see to what extent this coordination was multiplicative. A secondary goal was to document children's solutions for equal sharing problems in which the quantities had a common factor (other than 1). Data consisted of problem-solving interviews with students in 1st, 3rd, 4th, and 5th grades (n=112). We found two major categories of strategies: (a) Parts Quantities strategies and (b) Ratio Quantities strategies. Parts quantities involved children's partitions of continuous units expressed in terms of the number of pieces that would be created. Ratio quantities involved children's creation of associated sets of discrete quantities. Within these strategies, children drew upon a range of relationships among fractions, ratio, multiplication, and division to mentally or physically manipulate quantities of sharers and things to produce exhaustive and equal partitions of the items. Additionally, we observed that problems that included number combinations with common factors elicited a wider range of whole-number knowledge and operations in children's strategies and therefore appeared to support richer interconnections than problems with relatively prime or more basic number combinations.  相似文献   

Text messaging in the school lives of American high school girls     

Margaret Eisenhart  Erin Allaman 《Ethnography and Education》2018,13(2):235-253

Digital technologies open new windows for ethnographic explorations of cultural experiences. In this paper, we examine text messaging among academically talented teenage girls of colour at three US urban high schools. Texting introduced a new communication modality into the girls’ lives and created a space for new discourses mediating their participation in school. We draw on the concept of ‘serious play’ to reveal the paradoxical nature of the girls’ texting. At each school, distinct text-messaged discourses emerged – with implications for ethnographic studies of discourse and young people’s commitments to schooling.  相似文献   

The elaboration theory of instruction: A model for sequencing and synthesizing instruction   总被引：1，自引：2，他引：1  

Charles M. Reigeluth  M. David Merrill  Brent G. Wilson  Reginald T. Spiller 《Instructional Science》1980,9(3):195-219

This paper describes a novel instructional model for sequencing, syntheizing, and summarizing subject-matter content. The importance of such models is discussed, along with the need for a significant change in the role of subject-matter structure in instruction. A zoom-lens analogy is presented to facilitate an understanding of the elaboration model of instruction. Some basic concepts and principles upon which the model is based are described. The basic unvarying components of the elaboration model are described. And finally, some variations in the model for different kinds of goals are described. The elaboration model follows a general-to-detailed pattern of sequencing, as opposed to the hierarchically based sequences derived from Gagné-type task analyses.Many of the ideas described in this paper were developed under two projeets, one funded by Brigham Young University in Provo, Utah, and the other by the Navy Personnel Research and Development Center in San Diego, California; however, the ideas expressed do not necessarily constitute the opinions of the funding institutions.  相似文献   

Deviant Peer Factors During Early Adolescence: Cause or Consequence of Physical Aggression?     

Erin L. Thompson  Krista R. Mehari  Albert D. Farrell 《Child development》2020,91(2):e415-e431

This study investigated reciprocal relations between adolescents' physical aggression and their perceptions of peers' deviant behaviors and attitudes. Analyses were conducted on four waves of data from 2,290 adolescents (ages 10–16) from three urban middle schools. Autoregression models revealed reciprocal relations between peer factors (i.e., friends' problem behavior, peer pressure for fighting, friends' support for fighting) and adolescents' reporting of their aggressive behavior. Bidirectional relations were also found between peer pressure for fighting and adolescents' frequency of physical aggression based on teacher ratings. Findings were consistent across sex, grade, and time. Findings suggest that multiple dimensions of peers' behaviors uniquely play a role in the development of adolescents' aggression and have important implications for interventions to reduce problem behaviors.  相似文献   

Actions for sociopolitical consciousness in a high school science class: A case study of ninth grade class with predominantly indigenous students     

Bhaskar Upadhyay  Erin Atwood  Baliram Tharu 《科学教学研究杂志》2020,57(7):1119-1147

This case study explores how a group of Grade 9 students engaged in sociopolitical discourses and actions in a science class in a mostly indigenous student school in Nepal. The study used sociopolitical consciousness (SPC) as a framework to document and understand indigenous students’ SPC-oriented science interactions and subsequent social change actions. We used ethnographic methods of data collection over 6 months. The study focused on the actions of 4 girls and 2 boys belonging to the indigenous Tharu group. Data were analyzed using iterative qualitative methods. The study findings show that students are capable of engaging in critical thinking, critical reflecting, and taking actions for social change. Additionally, students are competent to link their experiences with social, structural, and political discrimination to the relevant science content they learn. The study presents four thematic findings related to SPC and science teaching and learning: Fostering social justice awareness in science class, fostering structural understanding of inequities in sickle cell disease, fostering sociopolitical actions for sickle cell disease, and the teacher's activist pedagogy for SPC in science learning. Implications of the study are that culturally relevant pedagogy helps indigenous students to become sociopolitically more aware of the links between science and social change. Adding aspects of critical pedagogies in science teaching could encourage students to become more sociopolitically reflective about science learning.  相似文献   

Parental assessment of peer play: Development and validation of the parent version of the Penn Interactive Peer Play Scale     

John Fantuzzo  Julia Mendez  Erin Tighe 《Early childhood research quarterly》1998,13(4):659-676

The purpose of this investigation was to evaluate the construct validity of the parent version of the Penn Interactive Peer Play Scale (PIPPS) and to compare it with the teacher version. PIPPS were collected on 297 urban Head Start children. The Parent PIPPS replicated the three-factor solution found with the teacher version, supporting the following constructs of peer play: Play Interaction, Play Disruption, and Play Disconnection. Factor matching and canonical correlational analyses examining the relationship between the parent and teacher versions of the PIPPS revealed significant one-to-one matches between hypothesized like factors. Additionally, analyses of overlapping variance between versions indicated a significant degree of overlap. Implications of the findings for involvement of parents in the assessment process and research on the continuity and discontinuity between home and school environments for low-income, urban children were discussed.  相似文献
