Internships are an effective way of connecting high school students in a meaningful manner to the sciences. Disadvantaged minorities have fewer opportunities to participate in internships, and are underrepresented in both science, technology, engineering, and mathematics majors and careers. We have developed a Summer Academic Research Experience (SARE) program that provides an enriching academic internship to underrepresented youth. Our program has shown that to have a successful internship for these disadvantaged youth, several issues need to be addressed in addition to scientific mentoring. We have found that it is necessary to remediate and/or fortify basic academic skills for students to be successful. In addition, students need to be actively coached in the development of professional skills, habits, and attitudes necessary for success in the workplace. With all these factors in place, these youths can become better students, compete on a more level playing field in their internships, and increase their potential of participating actively in the sciences in the future. 相似文献

In terms of international education, the concept of online education seems to be a growing trend. Edxonline.org, Minervaproject.com, and Udacity.com are all new massive online open courses (MOOCs)—education websites similar to Coursera offering students the ability to receive the best education from elite universities entirely online. The most tantalizing promise of a company like Coursera is the role it might play in improving education for the world's have-nots: high school dropouts, the global poor, and those less able to self-teach. 相似文献

ABSTRACTThe free press performs essential democratic functions, but widespread negative attitudes toward the press threaten its legitimacy and effectiveness as a check on formal institutions. In order to combat these attitudes, media organizations must understand who holds them and why. A survey-based study of U.S. adults (N?=?2052) focuses on associations between perceptions of the news media industry as a threat to political performance and a range of politically oriented behaviors (i.e. news media exposure, political talk, political participation). Analyses reveal a series of non-monotonic relationships. Group differences between those who hold the most extreme views concerning news-media-as-threat are also explored. The opposing groups are distinct in some important ways (e.g. ideology, race), but are also found to be surprisingly similar (e.g. income, education, gender, news media exposure). The results suggest new strategies for maintaining and restoring confidence in media organizations. 相似文献

We proposed a causal relationship between teachers’ perception of principal leadership behavior, school culture, and teacher and student commitment. We hypothesized that a concept we called principal “venturesomeness” would be related to a school culture that stresses accomplishment and mastery, which in turn would be related to teacher commitment, which in turn would predict student commitment to school. We define principal venturesomeness as the extent to which principals are seen as being willing to take risks, are innovative in their approach to instructional leadership, and in general display and encourage achievement‐oriented behavior. The model was tested in two different samples. The first sample was third‐ through six‐grade teachers and students from schools in Arizona. The second sample was third‐ through fifth‐grade teachers and students from Florida. The model was tested using LISREL VI. Many similarities existed between the models in the two samples. Principal Venturesomeness was a strong predictor of an Accomplishment Culture, which in turn was a strong predictor of Teacher Commitment. Contrary to our hypothesis, no relationship existed between Teacher Commitment and Student Commitment. The summary fit statistics indicate that the model did not explain the data adequately. The χ2/df ratio was greater than a rule‐of‐thumb 5.0 and the goodness‐of‐fit index was less than a rule‐of‐thumb .9 in both studies. Although the studies indicated some interesting conceptual relationships, it appears that the proposed model does not adequately explain the theoretical relationships between teacher perceptions, school culture, and teacher and student commitment. The studies do suggest one research direction not yet explored in the literature. That is, the relationship between teacher commitment and student commitment. More empirical work exploring how teacher commitment relates to student outcomes is encouraged. 相似文献

The alternatives of taking over failing schools or handing over resources for them to develop their own improvement strategies are recognized as ineffective in achieving improvement. When deciding how best to intervene in 26 self-managing schools, the Ministry of Education in New Zealand attempted to avoid the negative consequences of these alternatives by developing a partnership with the schools and their communities. This article documents both the difficulties experienced in the first intervention phase, dominated by concerns about respecting the schools’ autonomy, and the successes of the second phase, when the Ministry was more explicit about the school improvement tasks. 相似文献

Advances in cognitive science and educational research indicate that a significant part of spatial cognition is facilitated by gesture (e.g. giving directions, or describing objects or landscape features). We aligned the analysis of gestures with conceptual metaphor theory to probe the use of mental image schemas as a source of concept representations for students' learning of sedimentary processes. A hermeneutical approach enabled us to access student meaning-making from students' verbal reports and gestures about four core geological ideas that involve sea-level change and sediment deposition. The study included 25 students from three US universities. Participants were enrolled in upper-level undergraduate courses on sedimentology and stratigraphy. We used semi-structured interviews for data collection. Our gesture coding focused on three types of gestures: deictic, iconic, and metaphoric. From analysis of video recorded interviews, we interpreted image schemas in gestures and verbal reports. Results suggested that students attempted to make more iconic and metaphoric gestures when dealing with abstract concepts, such as relative sea level, base level, and unconformities. Based on the analysis of gestures that recreated certain patterns including time, strata, and sea-level fluctuations, we reasoned that proper representational gestures may indicate completeness in conceptual understanding. We concluded that students rely on image schemas to develop ideas about complex sedimentary systems. Our research also supports the hypothesis that gestures provide an independent and non-linguistic indicator of image schemas that shape conceptual development, and also play a role in the construction and communication of complex spatial and temporal concepts in the geosciences. 相似文献
