In the aftermath of the financial and economic recession of 2008, 130 Spanish students of five age groups (8 to 17 years) and two socioeconomic backgrounds were individually interviewed about unemployment and lower wages. The participants were presented with two hypothetical situations, and their responses were qualitatively and quantitatively analyzed. The results indicated that children bring their conceptions of work when attempting to explain those phenomena. Specifically, it was found that the explanations were closely associated with the comprehension of the notion of surplus value (i.e., the idea that workers create more value than the cost of their salaries), and that the development of this notion proceeds in three levels. Younger children were simply unaware of the capacity of workers to create value (Level 1), which gave rise to some alternative conceptions (e.g., the idea that money for salaries comes from external sources). The children within the age range of 12–13 began to understand that workers create some value (Level 2). At this level, however, the notion of surplus value was not fully understood, and the idea that money for salaries comes from external sources persisted in a variety of ways. From the ages of 13–14, the children begin to understand that a wage is the price of labor and that the employer earns a profit because workers create more value than the cost of their wages (Level 3). The article presents a discussion of the possible reasons behind the slow progress observed and highlights some suggestions for educational practice.

Mass media, particularly television, influence public conceptions and attitudes toward learning science. The discovery of
an original method that does not rely on self-reported viewing habits to measure the impact of television on students’ performance
in science arose from a study of a unit on electricity in a Physics course. In determining the number of television sets at
home and the number of hours of operation, data emerged that allowed an investigation of associations between each of these
variables and student performance in physics. A negative impact on performance was found in its consistent decrease as both
the number of sets and the time the sets are on increase. These results provide dramatic independent confirmation of the negative
impact of television viewing on achievement determined through meta-analysis of many studies, and are also consistent with
those in the literature at large, particularly from the Third International Mathematics and Science Study, and the National
Assessment of Educational Progress. Furthermore, the totally ‘blind’ participation of the subjects lends a degree of authenticity
rarely found in a classically designed study. The findings impact scientific literacy, since performance in science and conceptions
of science and scientists, are all inextricably linked. 相似文献

Working with scientists has been suggested as an effective way for high-school students to learn authentic science. However, little research has involved students’ perceptions of science learning environments in a university internship. This study drew on the theoretical framework of community of practice with cogenerative dialogues to design an internship program that aims to build a constructivist internship for students. Students who learned science in the internship program developed stronger constructivist learning perceptions than those who learned science in school. Specifically, students perceived that they had more opportunities to think independently of the instructors and other students. Three effective principles for program design are: (a) high school students conduct open-inquiry projects with the support of scientists; (b) high school students and scientists conduct cogenerative dialogues regularly to address issues and share experiences; and (c) high school students present their project proposals and scientific findings at open house events. Implications of the results are discussed. 相似文献

Introduction
Early identification and management of chronic kidney disease (CKD) is highly cost-effective and can reduce the risk of kidney failure progression and cardiovascular disease. In 2014, the Joint Croatian Working Group (JCWG) for laboratory diagnostic of CKD on the behalf of Croatian society of medical biochemistry and laboratory medicine (CSMBLM) and Croatian chamber of medical biochemists (CCMB) conducted a survey across Croatian medical-biochemistry laboratories to assess the current practice in this area of laboratory medicine. The aim of this study was to present the data collected through the survey and to give insight about laboratory diagnostics of chronic kidney disease in Croatia.Materials and methods
An invitation to participate in the survey was sent to all Croatian medical-biochemistry laboratories (N = 196). The questionnaire was designed in a form of questions and statements, with possible multiple answers, comprising 24 questions.Results
The response rate was 80/196 (40.8%). 39 answers were from primary medical-biochemistry laboratories. 31/78 (0.40) laboratories measure creatinine with non-standardized method (uncompensated Jaffe method). 58/78 (0.74) of laboratories that measure creatinine do not report eGFR values. Similar number of laboratories (58/80, 0.73) do not measure urine albumin or protein.Conclusions
There is a large heterogeneity among Croatian laboratories regarding measuring methods, reporting units and reference intervals (cut-off values), both for creatinine and urine albumin or protein. The two key prerequisites for CKD screening, automatic reporting of eGFR and albuminuria or proteinuria assessment, are not implemented nationwide. There is a need for harmonization in laboratory diagnostics of CKD in Croatia.Key words: survey, chronic kidney disease, estimated glomerular filtration rate (eGFR), albuminuria, proteinuria, creatinine, harmonization 相似文献45.

This case study discusses how educational entities collaborate in meaningful ways to address teaching force representation
and shortages in critical fields for diverse populations in urban education settings. The authors examined how the role of
a federally funded program, Academy for Teacher Excellence (ATE), at a Hispanic Serving Institution in Texas is creating preschool
through university level (P-20) collaborative partnerships with various community stakeholders to enhance college access for
minorities, specifically Latino students pursuing the teaching profession. Constant comparison analysis of the data uncovered
the following themes: (a) Building Relationships and Dialoguing across Partners, (b) Communicating Information and Outreach,
and (c) Networking and Leveraging Resources. Together, these foster a collaborative partnership among entities with the intention
of maximizing synergy and supporting the access, recruitment, and education of Latino teacher candidates who will become culturally
efficacious teachers of all students, but specifically for the growing number of Latino students in urban areas. 相似文献

This article speaks to the reality of the lived experiences of student of color in society today: navigating the structures of diversity in a white world. For many, the author’s story resonates with what they feel at their core of belonging and unbelonging. It answers the age old questions, “Who am I?” and “What is my purpose?” The article gives pre-service teachers of color the ability to claim agency about who they are and what their purpose is in life. The author’s story is one of self-authorship. With the hope that White middle class teachers will better understand their students, the author also gives insight into the struggles and realities student of color face on a daily basis. 相似文献

This research focuses on the study of the processes of collaborative solving of information problems and their impact on group learning outcomes. Forty-nine pairs of students solved three learning tasks with learning goals of increasing complexity: information selection, information interpretation, and interrelating concepts. We analysed two types of data: group work processes and group learning outcomes. The group work processes were assessed using eight dimensions, and group learning outcomes were evaluated in two ways: quality of the group written product, and shared correct knowledge. Findings reveal the significant influence of some aspects of the group work processes (such as searching for information, processing information, shared task regulation, the construction of shared knowledge, and emotional climate) in the group learning outcomes. Results also show that this influence is most evident in tasks with more complex learning demands. Finally, some educational proposals for school education are provided. 相似文献

The presentation of the intellectual work of others as their own by students is believed to be common worldwide. Punishments and detection software have failed to solve the problem and have important limitations themselves. To go to the root of the problem, we applied an online questionnaire to 344 university students and their 13 teachers. Our objective was to compare their views on plagiarism and to test nine hypotheses about causation. We found that both students and teachers know what plagiarism is and that each group blames itself to some extent. Students blamed their own attitude but also mentioned their need to cope with an unnecessarily heavy workload imposed by teachers. Teachers blamed impunity and their own failure in providing meaningful and creative student work. Only 8% of the students admitted to plagiarising contents and admission was independent of need for higher scores, years in the university, sex, age, occupation, career or living in a small city where educational resources are more limited. We found that Spanish language literature has given more attention to the students’ point of view than much of its English counterparts, and conclude that plagiarism can be prevented by an approach based mainly on a workload defined by teacher teams instead of isolated teachers; reduction of rote learning (associated with texts that are easy to copy and paste); assignment of individualised work that cannot be plagiarised (workshops, exhibitions, forums, portfolios, solving real cases, applying concepts to the student’s personal experience); and accompanying students along the whole process of producing the written work. 相似文献
