Our short-term longitudinal study explored undergraduate students' experiences with performing authentic science practices in the classroom in relation to their science achievement and course grades. In addition, classroom experiences (felt recognition as a scientist and perceived classroom climate) and changes over a 10-week academic term in STEM (science, technology, engineering, and mathematics) identity and motivation were tested as mediators. The sample comprised 1,079 undergraduate students from introductory biology classrooms (65.4% women, 37.6% Asian, 30.2% White, 25.1% Latinx). Using structural equation modeling (SEM), our hypothesized model was confirmed while controlling for class size and GPA. Performing science practices (e.g., hypothesizing or explaining results) positively predicted students' felt recognition as a scientist; and felt recognition positively predicted perceived classroom climate. In turn, felt recognition and classroom climate predicted increases over time in students' STEM motivation (expectancy-value beliefs), STEM identity, and STEM career aspirations. Finally, these factors predicted students' course grade. Both recognition as a scientist and positive classroom climate were more strongly related to outcomes among underrepresented minority (URM) students. Findings have implications for why large-format courses that emphasize opportunities for students to learn science practices are related to positive STEM outcomes, as well as why they may prove especially helpful for URM students. Practical implications include the importance of recognition as a scientist from professors, teaching assistants, and classmates in addition to curriculum that engages students in the authentic practices of science. 相似文献

Although previous research has shown that individuals take on aspects of the avatars they embody in virtual environments, studies have not yet tested whether this phenomenon, known as the Proteus effect, extends to traits that are undesirable to have, such as narcissism. A total of 133 female participants completed a shopping simulation in virtual reality. In this simulation, half embodied an avatar of Kim Kardashian, a celebrity known for her narcissistic behavior and materialistic purchases, while the other half embodied a generic female avatar of similar appearance. Participants then chose between luxury and nonluxury brands for a variety of objects. Results indicated that participants did not take on the luxury purchase behaviors of Kim Kardashian and in fact showed lower narcissism scores after embodying her than those embodying a generic avatar. These results suggest a self-serving component to the Proteus effect, in that individuals may only take on desired aspects of the avatars they embody and distance themselves from undesired aspects. 相似文献

The need for schools to support children and young people's mental and emotional health is increasingly emphasised in policy initiatives, yet the role of teachers in this has been under explored. This paper reports findings from qualitative, semi‐structured interviews with 14 school staff at eight secondary schools in England, examining emotional health and well‐being (EHWB) activities in which they were involved. Three emergent themes are discussed: (1) a strongly held belief that teaching and EHWB are inevitably linked; (2) a perception that many colleagues outside the study sample are reluctant to engage in EHWB work; and (3) a concern that teachers’ own emotional health needs are neglected, leaving them unable or unwilling to consider those of pupils. The findings endorse whole‐school approaches to emotional health, with a focus on teachers’ training and support needs and clearer aims, including consideration of how such work fits with the broader goals of schools. 相似文献

Development of Instruments to Assess Teacher and Student Perceptions of Inquiry Experiences in Science Classrooms 总被引:1,自引:0,他引:1

This study describes the development of two instruments to investigate the extent to which students are engaged in scientific inquiry. As a result of the instrument development process employed, each finalized instrument consisted of 20-items separated into five categories. Both instruments were found to be internally consistent, with high reliability estimates. Factor analysis showed two factors for each instrument that, while not clustering the items into the five categories, did show item clustering that is consistent with research literature about students’ engagement in inquiry experiences. Based on the analyses completed, the instruments appear to be useful instruments for use in comprehensive assessment packages for assessing the extent to which students are experiencing inquiry in science classrooms. 相似文献

The development of ethical standards by professional associations, boards, councils and colleges of teachers, responds in part to a moral imperative that teachers and school leaders be accountable to the wider community, and in part to a desire to enhance the overall professionalism of educators' behaviour. This article explores the conceptual and practical complexities inherent in defining ethical standards for the teaching profession with a particular focus on their questionable capacity for implementation. In combining empirical evidence from previously reported research studies with newly fabricated first person narrative responses to the evidence, the article seeks to illustrate the difficulty, if not the impossibility, of applying ethical standards to actual situations in any professionally and ethically satisfying way. It argues further that moral dilemmas facing teachers are potentially resolvable only by communities of educators internalizing and applying principles of ethics, not formalized codes or standards. 相似文献

The Goodenough–Harris Drawing Test (GHDT) is a non-verbal assessment designed to infer young children’s levels of intellectual development and understanding via the collection of three human figure drawings (HFDs) – one each of a man, a woman and a self-portrait. This paper presents findings from a research project that applied the Rasch model for measurement to HFDs collected from 246 children aged between 4 and 10 years to assess the psychometric properties of the GHDT assessment, and young children’s HFDs in general, as the GHDT had not yet been examined from a modern test theory perspective in full. Results indicated that: (1) the GHDT and children’s HFDs were apt for Rasch analysis and deemed to be generally psychometrically sound; and (2) that children performed almost identically (within error) on all three HFDs collected for the assessment, suggesting that the collection of three HFDs – as well as many of the 217 items which comprise the GHDT – was potentially redundant. Consequently, a prototype human figure drawing continuum (HFDC) was constructed from those data and examined. Rasch analysis revealed that the researcher-constructed 45-item HFDC scale – requiring just one self-selected HFD of a man, woman or child – was just as effective as the 217-item GHDT. The HFDC, when normed, should be seen as a parsimonious and child-friendly HDF assessment. 相似文献
