This study examines the transformation and dynamic nature of one teacher candidate’s (Susan) identity as a learner and teacher of science throughout an innovative science methods course. The goal of this paper is to use theoretically derived themes grounded in cultural-historical activity theory (CHAT) and situated learning theory to determine the ways in which Susan’s identity as a learner and teacher of science was influenced by her experiences in the course, and to describe how she made meaning of her transformative process. The following are the three theoretical themes: (1) learning contributes to identity development, (2) identity development is a dialogical process that occurs between individuals, not within individuals, and (3) social practice leads to transformations and transformations lead to the creation of new social practices. Within each theme, specific experiences in the science methods course are identified that influenced Susan’s identity development as a teacher of science. Knowing how context and experiences influence identity development can inform design decisions concerning teacher education programs, courses, and experiences for candidates. 相似文献

Despite the ease of accessing a wide range of measures, little attention is given to validity arguments when considering whether to use the measure for a new purpose or in a different context. Making a validity argument has historically focused on the intended interpretation and use. There has been a press to consider both the intended and actual interpretations and how users make sense of the data when constructing validity arguments, but the practice is not widespread. This paper contributes to existing research on validity by highlighting the value of attending to the actual interpretation and use of a measure aimed at supporting instructional improvement in mathematics. We describe the use of the same measure across two contexts to highlight the importance of attending to characteristics of both users and the contexts in which the measures are used when assessing the validity of inferences for the purpose of instructional improvement efforts. 相似文献

A number of scholars are exploring district and site relations in organizational change efforts in the larger policy context
of No Child Left Behind. These studies suggest the importance of the central office as a support to the work of reform and
offer strategies for building relations between district offices and sites in order to implement and sustain change efforts.
What is frequently overlooked in these studies is that organizational change efforts are often socially constructed. Therefore,
examining the underlying social networks may provide insight into structures that support or constrain efforts at change.
This exploratory case study uses social network analysis and interviews to examine the communication and knowledge network
structures of central office and site leaders in an ‘in need of improvement’ district facing sanctions under No Child Left
Behind. Findings indicate sparse ties among and between school site and central office administrators, as well as a centralized
network structure that may constrain the exchange of complex information and ultimately inhibit efforts at change. 相似文献

Dogs live in the dynamic human social networks full of strangers, yet they form strong and selective bonds with familiar caretakers. Little is known about how a bond is initially formed between a dog and a complete stranger. The first-impression hypothesis suggests that interacting with strangers can present an opportunity to form a mutualistic partnership. It predicts that dogs should respond positively toward a complete stranger to facilitate bonding (Prediction 1) and adjust their preferences in response to the perceived risk and benefit of interacting with strangers (Prediction 2). We examine the social preferences of pet dogs toward a complete stranger whom they have never met before and several other potential partners – the owner with whom subjects have had a positive, long-term bond (Experiment 1), and an exposed stranger with whom they have had a positive short-term interaction (Experiment 2) or a negative one (Experiment 3). In support of Prediction 1, subjects were exceptionally trusting across contexts. Mixed results were found with regard to Prediction 2. Subjects preferred their owner over a stranger when following social cues and (to a lesser degree) when approaching and feeding in close proximity. However, relative to a complete stranger, subjects did not consistently prefer the positively exposed stranger or avoid the negatively exposed one. The lack of clear selectivity might be due to pet dogs’ high baseline level of trust of complete strangers or reflect the strength of their existing bonds that negated the need for another positive bond with a new human partner. 相似文献

Counseling self-efficacy is defined as a counselor’s beliefs regarding their ability to counsel a client effectively. Larson et al. (1992) developed the Counseling Self-Estimate Inventory (COSE) to determine counselors’ self-efficacy in the dimensions of microskills, counseling process, difficult client behavior, cultural competence, and awareness of values. The COSE has been used widely in the United States as well as being adapted to other cultures. The purpose of the present study was to obtain validity and reliability evidence for the COSE in a Turkish sample towards the creation of a Turkish version (COSE-TR). Analyses regarding internal consistency and construct validity were undertaken via CFA and EFA, and divergent and convergent validity assessments were performed. The devised COSE-TR obtained a Cronbach alpha coefficient of .92. Exploratory factor analysis suggested a four-factor model with 53.82% of the total variance explained, which the CFA also supported. The COSE-TR correlated negatively with trait anxiety as measured on the ‘State-Trait Anxiety Inventory Scale’ (involving only Trait anxiety STAI-T; Spielberger 1983), but positively with generalized self-efficacy as measured via the ‘General Self-Efficacy Scale’ (GSE; Schwarzer and Jerusalem 1995). As for language equivalence, there was no difference between the means of total scores obtained from the original COSE and the created Turkish shorter version. Results revealed that the shortened COSE-TR can be regarded as a valid and reliable instrument for measuring counseling self-efficacy with Turkish counselors. Implications for counseling psychology, counselor education and supervision in developing nations and the transculturality of counseling self-efficacy are discussed. 相似文献

Comparing the Impacts of Tutorial and Edutainment Software Programs on Students’ Achievements, Misconceptions, and Attitudes towards Biology 总被引:2,自引:2,他引:0
The purpose of this study was to investigate the effects of tutorial and edutainment design of instructional software programs
related to the “cell division” topic on student achievements, misconceptions and attitudes. An experimental research design
including the cell division achievement test (CAT), the cell division concept test (CCT) and biology attitude scale (BAS)
was applied at the beginning and at the end of the research. After the treatment, general achievement in CAT increased in
favor of experimental groups. Instructional software programs also had the positive effect to the awareness of students’ understandings
to the general functions of mitosis and meiosis. However, the current study revealed that there were still some misconceptions
in the experimental groups even after the treatment. It was also noticed that only using edutainment software program significantly
changed students’ attitudes towards biology. 相似文献

This study examined how parents' reports of children’s technology use in the home varies by a child’s gender or grade level. Framed by technology adoption models, this mixed-method study gathered parent reports of their elementary child’s use of portable technology for entertainment and learning in the home, collected from 120 surveys and 13 individual interviews with survey respondents. Results across the four 2×2 ANOVAs yielded three significant main effects: gender and entertainment devices, gender and entertainment apps, grade level and learning apps. No significant effects were found among any of the interaction variables or within the ANOVA summary for learning devices. Interview data revealed girls are interested in reading with Kindle, whereas parents are reluctant to provide boys with portable technology because of their preference to play games. Strategies are provided for teachers, support specialists, and parents to improve how children use technology. Implications for app developers are suggested. 相似文献

The effects of school‐based ethnic diversity on student well‐being and race‐related views were examined during the first year in middle school. To capture the dynamic nature of ethnic exposure, diversity was assessed both at the school‐level (n = 26) and based on academic course enrollments of African American, Asian, Latino, and White students (n = 4,302; M = 11.33 years). Across all four pan‐ethnic groups, school‐level ethnic diversity was associated with lower sense of vulnerability (i.e., feeling safer, less victimized, and less lonely) as well as perceptions of teachers’ fair and equal treatment of ethnic groups and lower out‐group distance. Underscoring the role of individual experiences, exposure to diversity in academic classes moderated the association between school‐level diversity and the two aforementioned race‐related views. 相似文献
