This paper focuses on the kinds of notations young children make for fractional numbers. The extant literature in the area of fractional numbers acknowledges children's difficulties in conceptualizing fractional numbers. Some of the research suggests possibly delaying an introduction to conventional notations for algorithms and fractions until children have developed a better understanding of fractional numbers (e.g., Hunting, 1987; Sáenz-Ludlow, 1994, 1995). Other research (e.g., Empson, 1999), however, acknowledges the interaction between conceptual understandings and the representations for those understandings. Following the latter line of thinking, this paper argues that children's notational competencies and conceptual understandings are intertwined, addressing the following research questions: (a) What kinds of notations do five and six-year-old children make for fractional numbers?; and (b) What can be learned about young children's learning of fractional numbers by analyzing the notations they make? This paper presents data from interviews carried out with twenty-four children in Kindergarten and first grade (five and six-year-old children), exploring the nuances of their notations and the meanings that they attach to fractions. 相似文献

Zusammenfassung Im Rahmen einer berufsorientierten Hochschulausbildung sollte das studienintegrierte Praktikum eigentlich eine zentrale Rolle
spielen. Allerdings zeigt sich, dass das Praktikum weder in aktuellen Debatten zur Hochschulreform thematisiert wird noch
ein eigenst?ndiger Gegenstand von Hochschulforschung ist. An diesem doppelten Defizit setzt der folgende Beitrag an, in dessen
Mittelpunkt empirische Befunde aus einer Untersuchung zum studentischen Umgang mit dem Praktikum in den beiden Studienf?chern
Diplom-P?dagogik und Humanmedizin stehen. Unter der Frage, wie Studierende ihre au?eruniversit?r stattfindenden und selbst
zu organisierenden Praktika deuten, wurden nicht nur zwei gro?e Handlungsprobleme identifiziert, auf die Studierende im Zusammenhang
mit der Verpflichtung zum Praktikum treffen (übergang vom Studium ins Praktikum; Gestaltungszumutung), sondern auch die Deutungsmuster
rekonstruiert, auf die sie zur L?sung dieser Handlungsprobleme zurückgreifen. Die Studie zeigt, dass das Praktikum von Studierenden
trotz bestehender Vorgaben relativ autonom und in vielf?ltiger Weise, orientiert an Studium, Beruf, Biographie und Lebenswelt,
angeeignet wird und innerhalb des Studiums nicht nur einen besonderen Lern-und Erfahrungsraum, sondern auch einen Ort der
Bildung darstellt. Angesichts von Hochschulreformen, in denen dieser Bildungsgedanke zunehmend zu verschwinden droht, pl?diert
der Beitrag dafür, derartige Freir?ume für selbstbestimmtes und kreatives Handeln zu erhalten und die Aneignungsleistungen
der in der Hochschule agierendenden Individuen im Rahmen von Hochschulplanung künftig st?rker zu berücksichtigen.
<blockquote> Summary Internship as open space An integrated internship should actually play a central role within the framework of a vocationally-oriented higher education. However, it must be observed that internships are neither a topic of current reform debates nor a specific object of higher education research. This contribution starts out from this double deficit and focuses on empirical results from an investigation into how students view internships in two courses — pedagogy and human medicine. On the basis of the question of how students perceive their internships, which occur outside of the university and are organized by themselves, two significant problems which students have to cope with are identified (transition between studies to internship; obligation to self-motivation), and implicit patterns of construction may be investigated, which reflect the solutions to these problems. The study shows that despite formal expectations, internships are often approached in an autonomous and multifarious way, and reflect course of study, job, biography and life-world. Therefore their position within a course should not simply be seen as a particular space for learning and accumulated experience, but also as a general place of personal development (Bildung). In the face of higher education reform in which the disappearance of Bildung is a serious threat, this contribution argues that such open spaces for self-determined and creative action should be maintained and recognized more explicitly in future higher education planning. blockquote> 相似文献

作为清朝重要的文学家,徐子苓的生平却鲜为人知。关于其生平的记述,或语焉不详,或讹误甚多,故考述其生平显得尤其迫切与紧要。同时,作为清代桐城派的嫡传,徐子苓在文学上亦颇有成就。其散文取材广泛,文风纵横超轶,长于叙事而又不拘一格;其诗学杜,诗风鸷悍,内容则多取材于现实生活,后世对其诗评价很高。 相似文献

“鸡不吃了”,那“鸡”既可以理解为“吃”的施事,也可以理解为“吃”的受事。这是汉语语法研究与教学中作为有歧义的一个经典例子。王士元先生在前人解释的基础上进一步作了新的解释——从词汇角度,具体说从“词的词义延伸”的角度来加以解释,有可取之处,也有考虑不周之处。 相似文献

In recent years questions concerning the impact of public research funding have become the preeminent site at which struggles
over the meanings and value of science are played out. In this paper we explore the ‘politics of impact’ in contemporary UK
science and research policy and, in particular, detail the ways in which UK research councils have responded to and reframed
recent calls for the quantitative measurement of research impacts. Operating as ‘boundary organisations’ research councils
are embroiled in what might be characterised as the ‘politics of demarcation’ in which competing understandings of the cultural
values of science are traded, exchanged and contested. In this paper we focus on the way the UK’s ‘Engineering and Physical
Sciences Research Council’ (EPSRC) has responded to contemporary policy discourses concerning the impacts of public research
expenditure. We argue that, in response to the shifting terms of contemporary science policy, the EPSRC has adopted three
distinct strategies. Firstly, in collaboration with other research councils the EPSRC have emphasised the intellectual and
metrological challenge presented by attempts to quantify the economic impact of public research expenditure, emphasising instead
the cumulative impacts of a broad portfolio of ‘basic science’. Secondly, the EPSRC has sought to widen the discursive meaning
of research impacts – specifically to include societal and policy impacts in addition to economic ones. Thirdly, the EPSRC
has introduced a new framing into the ‘impact agenda’, preferring to talk about ‘pathways to impact’ rather than research
impacts per se. In responding to government priority setting, we argue that the EPSRC has sought to exploit both the technical fragility
of auditing techniques and the discursive ambiguity of notions of impact. 相似文献
