Science notebooks as interactional spaces in a multilingual classroom: Not just ideas on paper     

Sara E.D. Wilmes  Christina Siry 《科学教学研究杂志》2020,57(7):999-1027

Past studies have explored the role of student science notebooks in supporting students' developing science understandings. Yet scant research has investigated science notebook use with students who are learning science in a language they are working to master. To explore how student science notebook use is co-constructed in interaction among students and teachers, this study examined plurilingual students' interactions with open-ended science notebooks during an inquiry science unit on condensation and evaporation. Grounded in theoretical views of the notebook as a semiotic social space, multimodal interaction analysis facilitated examination of the ways students drew upon the space afforded by the notebook as they constructed explanations of their understandings. Cross-group comparison of three focal groups led to multiple assertions regarding the use of science notebooks with plurilingual students. First, the notebook supported student-determined paths of resemiotization as students employed multiple communicative resources to express science understandings. Second, notebooks provided spaces for students to draw upon diverse language resources and as a bridge in time across multiple inquiry sessions. Third, representations in notebooks were leveraged by both students and teachers to access and deepen conceptual conversations. Lastly, students' interactions over time revealed multiple epistemological orientations in students' use of the notebook space. These findings point to the benefits of open-ended science notebooks use with plurilingual students, and a consideration of the ways they are used in interaction in science instruction.  相似文献

Diversity at Work: Do Men and Women Differ in their Organizational Citizenship Behavior?     

Christina L. Stamper  Linn Van Dyne 《Performance Improvement Quarterly》1999,12(1):59-76

ABSTRACT : In this paper, we use social role theory to develop hypotheses predicting differences in the organizational citizenship behavior of males and females at work. Results, based on questionnaire responses of 257 restaurant workers and their supervisors, demonstrate that females in our service-worker sample engaged in more altruism, loyalty, and obedience than males, but that males and females did not differ in their advocacy participation. Results also demonstrate that organizational tenure moderated the relationship between sex and two forms of citizenship behavior: altruism and advocacy participation. We discuss the implications of our findings and conclude with suggestions for future research.  相似文献

Gender theory as a tool for analyzing science teaching     

Kristina Andersson  Anita Hussénius  Christina Gustafsson 《Teaching and Teacher Education》2009

This study examines to what extent experienced teachers are aware of gender issues in the science classroom. It also explores how an introduction to gender theory might alter this awareness. Teachers wrote their reflections about a real classroom situation. They were then asked to analyse the same situation after having read texts that discussed gender theory concepts. The fourteen teachers' understanding about gender and society were challenged. Some teachers were able to analyse the case differently by applying gender theory, others discussed the case on a more general level, while one teacher showed signs of resistance regarding gender theory.  相似文献   

What Happens Next? Follow-Up From the Children's Toddler School Program     

Akshoomoff N  Stahmer AC  Corsello C  Mahrer NE 《Journal of Positive Behavior Interventions》2010,12(4):245-253

This study was a follow-up of a group of 29 children diagnosed with autism spectrum disorders at age 2 who attended an inclusive toddler program until age 3. Children ranged in age from 4 to 12 years at the time of the parent survey and follow-up testing. The majority of children were placed in a special education (noninclusive) preschool class, but among the children who were in elementary school at the time of follow-up, 63% were in general education classroom placement. Diagnoses of autism spectrum disorders remained stable, socialization skills remained a weakness, and child-related parental stress remained high despite average cognitive and language skills in the majority of children. Social skill development and support remained a service need.  相似文献   

Programming Time as a Function of Movement Constraint     

Andrew M. Gordon  Robert W. Christina 《Research quarterly for exercise and sport》2013,84(1):92-97

Abstract

Although the benefits of exercise are well documented, an international problem of physical inactivity exists. More research, especially theory based, has been recommended. One promising approach for studying exercise behavior is that proposed in the Transtheoretical Model (TTM) of behavior change. This model, however, has received minimal cross-cultural attention and, relative to the current study, measurement instruments have only recently been translated into the Finnish language. The purpose of this study was to assess American and Finnish college students' exercise behaviors on the basis of TTM. Participants were American (n = 169) and Finnish (n = 168) college students who completed language-specific measures of exercise behavior, stage of change, processes of change, decisional balance, self-efficacy, and temptation. The only cultural difference observed was that the American participants rated themselves higher on barrier self-efficacy relative to the Finnish participants. Regardless of nationality or gender, participants classified by their stage of change differed on all the core constructs assessed. These results generally support the utility of TTM for understanding American and Finnish college students' exercise behavior.  相似文献   

Attention Demands of Precision Pistol-Shooting as a Function of Skill Level     

Debra J. Rose  Robert W. Christina 《Research quarterly for exercise and sport》2013,84(1):111-113

This study provided initial validity evidence for multidimensional measures of coaching competency derived from the Coaching Competency Scale (CCS). Data were collected from intercollegiate men's (n = 8) and women's (n = 13) soccer and women's ice hockey teams (n = 11). The total number of athletes was 585. Within teams, a multidimensional internal model was retained in which motivation, game strategy, technique, and character building comprised the dimensions of coaching competency. Some redundancy among the dimensions was observed. Internal reliabilities ranged from very good to excellent. Practical recommendations for the CCS are given in the Discussion section.  相似文献
