Genetics with Jean: the design,development and evaluation of an affective tutoring system

This paper details the design, development and evaluation of an affective tutoring system (ATS)—an e-learning system that detects and responds to the emotional states of the learner. Research into the development of ATS is an active and relatively new field, with many studies demonstrating promising results. However, there is often no practical way to apply these findings in real-world settings. The ATS described in this paper utilizes a generic affective application model to infer and appropriately respond to the learner’s affective state. This approach brings several advantages, notably the potential direct support for re-use and retrospective addition of affect sensing functionality into existing e-learning software. Skin conductivity and heart rate variability measurements were used to infer affective activation and valence. The evaluation involved an experiment in which the effectiveness of the fully functional ATS was compared with that of a non-affective version, and was conducted with 40 adult participants. The evaluation of the effectiveness of this tutoring system showed that measurable improvements in perceived learning may be obtained with a modest level of software development.     

A meta-ethnography of two studies on interactions in schools: reflections on the process of translation

ABSTRACT

This paper reflects upon our experience gained from engagement in a meta-ethnography of two studies on interactions between teachers and students in schools situated in England and Germany. Starting with a short overview of Noblit and Hare’s (1988 Noblit, G. W., and R. D. Hare. 1988. Meta-Ethnography: Synthesizing Qualitative Studies. Newbury Park, CA: Sage.[Crossref] , [Google Scholar]) conceptualisation of the method, the paper outlines the meta-ethnography we undertook especially focusing on the process of translation. We present the findings of our study which show teachers’ understanding of the pastoral aspect of their role as incompatible with demands related to their performance and to those associated with their institutional responsibilities. We show also how attempts to develop personalised interactions with students may reinforce students’ vulnerability. Our final discussion contributes our own deliberations about the potentials and challenges of the method, especially in relation to the role of the ethnographers and their relationship to the meta-ethnographic field.     

Negative Keying Effects in the Factor Structure of TIMSS 2011 Motivation Scales and Associations with Reading Achievement

ABSTRACT

The Student Background survey administered along with achievement tests in studies of the International Association for the Evaluation of Educational Achievement includes scales of student motivation, competence, and attitudes toward mathematics and science. The scales consist of positively- and negatively keyed items. The current research examined the factorial structure of the 18-item motivational scales in fourth-grade mathematics in the 2011 Trends in International Mathematics and Science Study (TIMSS). Survey data from six European countries were analyzed. In comparisons of alternative models, the fit was adequate when three correlated factors were specified and negative keying was taken into account as a latent factor, or with correlated uniquenesses among negatively keyed items. Participants reading achievement scores correlated systematically to negative keying with coefficients ranging from .254 to .395 in the six samples. Unlike their higher-scoring peers, fourth-graders with lower reading achievement responded differentially to similar items depending on the direction of item keying, in such a way that their motivation scores were biased downward. Implications about the use of reverse keying in surveys for young students are discussed.     

Market orientation in managing relationships with multiple constituencies of Croatian higher education

In this paper, market orientation in Croatian higher education (HE) is discussed within the context of stakeholder-oriented management. Drawing on existing studies, the ‘classical’ empirical model, describing the market orientation of generic nonprofit organisations, has been adapted to the contingencies of the Croatian HE sector. Empirical testing of the model, based on primary data drawn from the majority of public institutions of higher learning in the country, reveals inadequate market orientation toward the relevant stakeholders. Although social market orientation currently does not exist in Croatian HE institutions, the empirical results confirm that it might be possible to initiate a ‘virtuous circle’, in which relevant market orientation and stakeholder management practices, directed toward one or other of the stakeholders, simultaneously enhance orientation toward the other stakeholders. Unfortunately, the current situation in HE is not satisfactory, which could hinder the implementation of development of knowledge society in Croatia.

Bridging distant technological domains: A longitudinal study of the determinants of breadth of innovation diffusion

The diffusion of innovations is identified as an important aspect of technological and social change. Innovations diffuse through segmented networks of knowledge that limit the flow of knowledge from any one technological domain to any other. Despite this segmentation, some organizations are capable of developing pieces of knowledge that overcome these limitations. Within this context, we develop four hypotheses regarding specific R&D strategies that affect a firm’s ability to develop inventions that diffuse beyond the firm’s technological boundaries. Specifically, we examine how a firm's scientific intensity, technological collaborations, technological diversity, and internal focus impact breadth of innovation diffusion. We use two of the main determinants of innovation diffusion, namely, the relative advantage and the observability, as theoretical mechanisms to build our arguments. We empirically test our hypotheses on longitudinal data from the industries of pharmaceuticals, biotechnology, and chemicals. Our findings show that the extent to which the knowledge embedded in a firm’s inventions diffuses in distant technological areas is positively related to the firm’s scientific intensity and to its extent of collaboration, but it is negatively related to its technological diversity.
