Background questionnaires of PISA : a study of the assessment indicators
2016
El sistema de evaluación de PISA ha generado y continúa generando intensos debates sobre su estructura y utilidad. Este artículo se centra en los cuestionarios de contexto, como forma de analizar y entender de manera adecuada los resultados. Los objetivos son analizar los indicadores de contexto que se utilizan en las distintas ediciones de las pruebas PISA, su utilización en distintos estudios y en los resultados de estos estudios. Se proporciona una visión general del modelo utilizado para conseguir que estos indicadores dejen de ser algo que acompaña a las prueba de rendimiento para que alcancen su verdadero sentido: analizar conjuntamente el rendimiento junto con las variables que…
Factors of Development of the Management of the Design Education in Latvia
2015
<p>The author proceeds with the discussion of significant problems in design industry and education in Europe and Latvia. This research is devoted to several important aspects in the development of design education in Latvia. Design education which is mainly based on the meaning of design as an aesthetic component of products, environment or communication, includes only a narrow range of specializations in the traditional fields of design. This concept affects the structure of design education and an beliefs of the areas in which designers will be able to work. Insufficiency of public awareness and understanding of the essence of design results in limited demand of design products and…
Reflections on dialogicity: Challenges and suggestions by mathematics student teachers
2021
Abstract Research related to dialogic teaching has been gaining ground in recent decades. On a theoretical level, researchers have described how sociocultural approaches are linked to dialogic teaching. In addition, empirical studies have explained how dialogic teaching manifests itself in educational dialogue and classroom interactions. However, studies addressing how the dialogic theory and practice could be linked meaningfully in teacher education and professional development programs in subject teacher education and related praxis are still limited. Especially in the case of math teacher education, the reported professional development programs are limited in number. Whereas the tendenc…
Inquiry-Based Approaches in Primary Science Teacher Education
2018
This chapter introduces an interactional graphic tool together with a model for inquiry-based science teaching (abbreviated as IBST). The combination of the graphic tool and model offers an approach to support the planning, implementation, reflection and analysis of dialogic IBST. The potential use is illustrated here using a case study in which student teachers used IBST to develop their teaching. The interactional graphic and the model are fundamentally related to three established approaches to science teaching: inquiry-based science teaching, dialogic teaching and the communicative approach. Together, these approaches draw attention to learner participation in inquiry-based science teac…
Two-dimensional filters for structured text
1997
The paper introduces a method for defining filters for structured text. In the method, the text structure is originally defined by a grammar consisting of a set of productions. To describe the information interests, a two-dimensional template is first created interactively from the grammar to show the structure of a set of textual elements, at a chosen level of detail. The template depicts the hierarchical structure of the elements and indicates also optionality, alternatives, and iteration in the structure. Then, the template is filled by constraints and annotations. The constraints allow giving conditions to the content of parts, to the position of parts in an ordered set of parts, and to…
The impact of user’s availability on On-line Ego Networks: a Facebook analysis
2016
We have defined and implemented a Facebook application to log a Facebook dataset.We have studied and validated the structural properties of the whole dataset and of the Dunbar ego networks.We have analyzed the interactions of the users.The availability of the users in the Dunbar ego networks have been investigated.Our results reveal the presence of the temporal homophily property in the Dunbar ego networks. Online Social Networks (OSNs) are the most popular applications in todays Internet and they have changed the way people interact with each other. Understanding the structural properties of OSNs and, in particular, how users behave when they connect to OSNs is crucial for designing user-c…
Designed for Regional Engagement? The Case of Telemark University College
2018
Established in 1994 through a forced merger between various multiple regional education providers, Telemark University College (HIT) is one of the largest and most decentralised university colleges in Norway. This chapter investigates to what extent the adopted decentralised, multi-campus model has (a) had an effect on organisational dynamics more generally and (b) more specifically how it enables or constrains HIT’s regional role. In so doing, we cast light on a critical tension resulting from the so-called ambiguity of structure inherent in universities as organisations. Our findings show that HIT’s campuses enjoy considerable degrees of autonomy, have overlapping tasks and seemingly conf…
Rural Municipalities and Change in Local School Structure: Comparing Room of manoeuvre among Rural Municipalities in Latvia and Norway
2018
Rural depopulation, decreasing numbers of children and general centralization combined with high expectations to education, are factors that challenge rural communities and school structures in Latvia and Norway. The ambition of this article is to explore and compare the role of the municipality and other levels of governance in making decisions on school structure in rural municipalities. The research method is a multiple case study approach, supported by survey data. Through the lenses of multi-level governance theory, we have investigated how national frames like regulations and educational expectations are affecting local decision-making. Local politicians navigate between national fram…
The Structure and Behavioural Effects of Revealed Social Identity Preferences
2020
A large body of evidence shows that social identity affects behaviour. However, our understanding of the substantial variation of these behavioural effects is still limited. We use a novel laboratory experiment to measure differences in preferences for social identities as a potential source of behavioural heterogeneity. Facing a trade-off between monetary payments and belonging to different groups, individuals are willing to forego significant earnings to avoid belonging to certain groups. We then show that individual differences in these foregone earnings correspond to the differences in discriminatory behaviour towards these groups. Our results illustrate the importance of considering in…
