The purpose of the study was to determine what percentage of Palestinian science teachers held beliefs about knowledge and
learning that are congruent with the recent constructivist/conceptual change epistemological basis of science education, what
factors influence these beliefs, and if the beliefs about knowledge and learning were related. Two questionnaires were developed
to probe teachers' beliefs in these two areas, and a sample consisting of 91 teachers with varying educational background
and teaching levels responded to these questionnaires. The study showed that only a small percentage of Palestinian teachers
subscribed to the recent views of learning and scientific knowledge (25% and nine percent respectively). With regard to the
views of learning, this was mainly due to very few teachers believing or realising that students hold alternative preconceptions
and that science learning entails conceptual change. Very few teachers also believed that science itself develops through
conceptual change. Indeed, more than 80% believed that science develops through accretion and about 40% preferred the inductive
model of science to the hypothetico-deductive one which only 11% preferred. It was found that these views were not related
to the teachers' years of schooling, years of experience, level at which they taught, or teacher specialisation. The two views
of learning and knowledge were moderately related. The results and implications for future studies are discussed. 相似文献
Only recently have theorists and practitioners begun to consider and investigate the applications of developmental psychology to the delivery of career services. While there are several conceptual approaches to understanding the process of career development in general, the focus of this paper will be limited to the under-standing of career development in a college age population. In addition, the practical implications generated by this conceptual understanding will be discussed especially as they relate to the delivery of career services in higher education. 相似文献
A legacy emphasis was one of the fundamental pillars of the London 2012 Olympic Games. The notion of an Olympic legacy was predicated on assumptions that the event's value would not purely derive from the sporting spectacle, but rather from the ‘success’ of enduring effects met out in London and across the country. For physical education students and practitioners, Olympic legacy agendas translated into persistent pressure to increase inspiration, engagement, participation and performance in the subject, sport and physical activity. Responding to this context, and cognizant of significant disciplinary scholarship, this paper reports initial data from the first phase of a longitudinal study involving Key Stage Three (students aged 11–13) cohorts in two comparable United Kingdom schools: the first an inner-city (core) London school adjacent to the Olympic Park in Stratford, East London (n = 150); the second a (peripheral) school in the Midlands (n = 198). The research involved the use of themed questionnaires focusing on self-reported attitudes towards the Olympic Games and experiences of physical education, sport and physical activity. Students from both schools demonstrated a wide variety of attitudes towards physical education and sport; yet, minor variances emerged regarding extreme enthusiasm levels. Both cohorts also expressed considerably mixed feelings towards the impending Olympic Games. Strong and variable responses were also reported regarding inspiration levels, ticketing acquisition and engagement levels. Consequently, this investigation can be read within the broader context of legacy debates and aligns well with physical educationalists' ongoing discomfort regarding legacy imperatives being enforced upon the discipline and its practitioners. Our work reiterates a shared disciplinary scepticism that while an Olympic Games may temporarily affect young peoples' affectations for sport (and maybe physical education and physical activity), it may not provide the best, or most appropriate, mechanism for sustained attitudinal and/or social changes en masse. 相似文献
Argumentation has been emphasized in recent US science education reform efforts (NGSS Lead States 2013; NRC 2012), and while existing studies have investigated approaches to introducing and supporting argumentation (e.g., McNeill and Krajcik in Journal of Research in Science Teaching, 45(1), 53–78, 2008; Kang et al. in Science Education, 98(4), 674–704, 2014), few studies have investigated how game-based approaches may be used to introduce argumentation to students. In this paper, we report findings from a design-based study of a teacher’s use of a computer game intended to introduce the claim, evidence, reasoning (CER) framework (McNeill and Krajcik 2012) for scientific argumentation. We studied the implementation of the game over two iterations of development in a high school biology teacher’s classes. The results of this study include aspects of enactment of the activities and student argument scores. We found the teacher used the game in aspects of explicit instruction of argumentation during both iterations, although the ways in which the game was used differed. Also, students’ scores in the second iteration were significantly higher than the first iteration. These findings support the notion that students can learn argumentation through a game, especially when used in conjunction with explicit instruction and support in student materials. These findings also highlight the importance of analyzing classroom implementation in studies of game-based learning.
Receptive vocabulary of Hispanic children in Miami was tested in both English and Spanish with complementary standardized tests, the Peabody Picture Vocabulary Test (PPVT-R) and the Test de Vocabulario en Imágenes Peabody (TVIP-H). 105 bilingual first graders, of middle to high socioeconomic status relative to national norms, were divided according to the language(s) spoken in their homes. Both groups, whether they spoke only Spanish in the home (OSH) or both English and Spanish in the home (ESH), performed near the mean of 100 in Spanish receptive vocabulary (TVIP-H means 97.0 and 96.5); in contrast, ESH group children scored more than 1 SD higher in English than OSH group children (PPVT-R means 88.0 and 69.7, respectively). It appears, therefore, that learning 2 languages at once does not harm receptive language development in the language of origin, while it does lay the groundwork for superior performance in the majority language. Furthermore, an analysis of translation equivalents, items shared by both tests, shows that a statistically significant portion of bilingual children's lexical knowledge does not overlap in their 2 languages and is therefore not reflected in single-language scores. 相似文献
Zusammenfassung Dieser Artikel besch?ftigt sich mit einem Themengebiet, das in der erziehungswissenschaftlichen Wissenschafts-, Hochschul-und
Berufsforschung bislang kaum analysiert worden ist. Unter Bezug auf die Ergebnisse einer schriftlichen Befragung von rund
3.800 Absolventen erziehungswissenschaftlicher Hauptfachstudieng?nge (Diplom, Magister) in ganz Deutschland wird die Frage
untersucht, wie gro? die Gruppe der Studierenden aus diesen Studieng?ngen ist, die sich einige Jahre nach dem Studienabschluss
im Arbeitsfeld Hochschule und Forschung beruflich platzieren kann bzw. promoviert, durch welche Merkmale diese Gruppe gekennzeichnet
ist und welche Bedingungsfaktoren den Weg in die Wissenschaft beeinflussen. Nach einem überblick über den bisherigen Stand
der Forschung und der Darstellung zentraler Resultate des Diplom-und Magister-Surveys zum Weg in die Wissenschaft werden abschlie?end
einige Konsequenzen diskutiert, die sich aus den Befunden für eine Reform der bisherigen Hauptfachstudieng?nge bzw. für die
zukünftige Gestaltung neuer Studieng?nge mit Blick auf eine Verbesserung der Nachwuchsf?rderung für das Fach Erziehungswissenschaft
ergeben.
Summary
Paths into Science: The Results of a National Survey of Graduates from Diplom and Magister Programs in Educational Science
This article examines a topic which has hardly been dealt with in the field of Educational Science. A survey of around 3,800
graduates of Educational Science in both Diplom and Magister programs in Germany asked what proportion of graduates went on to work or commence a Ph.D. in higher education. It also investigated
the characteristics of such graduates and the conditions which determined their path into science. Following an overview of
preceding research in this area and a presentation of the central results of the survey, the consequences of the findings
for a reform of courses and an improvement in the training of academics in the field of Educational Science will be discussed.
Research on and about queer people and topics in higher education continues to evolve, expand, and push boundaries on identity, policy, and programming, increasingly informed by our narratives and experiences. Thus far, this work has done little to dismantle the imposed binary of researcher and subject(s), relegating queer research and practice as something that is done ‘on,’ ‘to,’ or ‘for’ queer people, rather than ‘with’ them. Collaborative ethnographic methodologies and communities of practice (CoP) provide alternative modes of scholarship and practice that build queer people’s agency through active involvement in research and social change processes. Situated in two of our own examples, our purpose is to explore big questions and raise even more. This article calls for a further queering of LGBTQ research in higher education by utilizing collaborative methodologies such as CoP and collaborative ethnography to improve the strategies, practices, and knowledge of campus queer communities and imagining new democratic and liberatory realities together. 相似文献
In prehistoric times carbon wasknown in the form of soot andcharcoal. Ever since AntoineLavoisier in 1792 and Smithson Te-net in 1797 demonstrated that dia-mond and graphite are allotropicforms of carbon[1], people have beeninterested in converting the relativelyabundant carbon materials into muchrarer diamond. It is found that dia-mond burnt in oxygen yields exactlythe same amount of carbon dioxideas that produced by burning the sameweight of carbon, proving diamondconsists of pure carbon.S… 相似文献
The effect of iodine deficiency (ID) on thyroid function in African women during pregnancy and postnatal period was examined,
for which very limited information is available. Serum T4, T3, TSH, TBG, thyroxine binding capacity (TBK), free thyroxine index (FT4I=T4/TBK) and T4/TBG were determined by ELISA technique in 32 pregnant women (resident of Plateau state, Nigeria- an ID zone) through pregnancy
upto term delivery, and in 5 women up to 6 weeks post delivery. Urinary iodide level was measured at delivery to determine
the degree of iodine deficiency. Results were matched with a non pregnant control comprising 44 subjects. 5555 birth weights
(BW) of term babies in the region were analysed to determine the prevalence of ‘small for dates’ (SFD) babies in the population.
Results show that the level of serum FT4I was elevated very significantly at late gestation (P<.001) but the women were not hyperthyroid, suggesting a marked disturbance
in binding of T4 with TBG during pregnancy. Five women with SFD babies were found in ‘compensated hypothyroid state’ and showed a significant
depression (p<.01) in serum T4/TBG, T4, FT4I and T3 levels to a low normal range, with a concurrent significant rise (p.<.001) in TSH level (above normal range) throughout pregnancy.
Incidence of SFD babies was higher (p.<.001) in ID zone (Bassa 15.2%) compared to control zone (Jos 9.8%). It is concluded
that a state of maternal ‘subclinical (compensated) hypothyroidism’ during pregnancy possibly plays an important role in the
aetiopathogenesis of SFD babies in Africans. A normal reference range for thyroid parameters at various stages of pregnancy
in healthy African women is established for the first time. 相似文献
