Authors from the periphery countries choose open access more often

This article analyses attitudes of academic authors toward open access (OA) and the frequency of choosing OA publication venues. The research looks particularly at differences between authors based in countries with a gross domestic product per capita less or greater than US$18,000 (called periphery and core countries, respectively). The data were obtained with an online survey sent to 107,296 scholars listed on the mailing lists belonging to De Gruyter Open from December 2015 to January 2016. A total of 1,012 responses were received. Authors from the periphery countries publish their articles in gold OA more often and they also pay OA publication fees equally often as those based in the core countries. The reasons for that are complex, involving both their preference to publish in OA and the composition of the publishing market in the periphery.     

Cytocompatible cellulose nanofibers from invasive plant species Agave americana L. and Ricinus communis L.: a renewable green source of highly crystalline nanocellulose

In this study, the fibers of invasive species Agave americana L. and Ricinus communis L. were successfully used for the first time as new sources to produce cytocompatible and highly crystalline cellulose nanofibers. Cellulose nanofibers were obtained by two methods, based on either alkaline or acid hydrolysis. The morphology, chemical composition, and crystallinity of the obtained materials were characterized by scanning electron microscopy(SEM) together with energy-dispersive X-ray spectroscopy(EDX), dynamic light scattering(DLS), X-ray diffraction(XRD), and Fourier transform infrared(FTIR)spectroscopy. The crystallinity indexes(CIs) of the cellulose nanofibers extracted from A. americana and R. communis were very high(94.1% and 92.7%, respectively). Biological studies evaluating the cytotoxic effects of the prepared cellulose nanofibers on human embryonic kidney 293 T(HEK293 T) cells were also performed. The nanofibers obtained using the two different extraction methods were all shown to be cytocompatible in the concentration range assayed(i.e., 0-500 μg/mL). Our results showed that the nanocellulose extracted from A. americana and R. communis fibers has high potential as a new renewable green source of highly crystalline cellulose-based cytocompatible nanomaterials for biomedical applications.     

A mentor’s aid in developing the competences of teacher trainees

The induction period is a very important time in the career of a teacher and has a long‐term influence on the teacher’s professional development, efficacy, job satisfaction and the length of his/her career. One of the key roles in this period is played by the trainee’s mentor. This paper presents the results of the extensive project ‘Partnership of Faculties and Schools’, carried out at the Pedagogical Faculty, University of Ljubljana, with the financial support of the European Social Fund and the Slovenian Ministry of Education, Science and Sport. We studied an induction project involving 361 teacher trainees and 331 mentors. The study reveals the trainees’ expectations towards their mentors and the mentors’ and trainees’ evaluations of how the mentor aids a teacher trainee in developing their competences.     

Feedback in Distance Learning Programmes in Languages: Attitudes to linguistic faults and implications for the learning process

In distance learning provision in languages, fault correction and feedback can facilitate teacher–student dialogue. This article examines teachers’ beliefs and assumptions about faults and the attitudes of both teachers and learners towards the correction process, all of which can play a key role in fostering this dialogue. Our findings are based on two surveys, one of 215 students enrolled on an intermediate Open University Spanish course and one of a sample of 18 tutors who teach on this course. The results of the two questionnaires suggest that the strategies currently in use for identifying and correcting faults may not be explicit enough. We conclude that this problem may be addressed if both tutors and students are given the tools to make the process more transparent and are encouraged to see dialogue as an essential component in the feedback mechanism.     

Student teachers’ beliefs about the teacher’s role in inclusive education

The main aim of this research is to examine the basic features of student teachers’ professional beliefs about the teacher’s role in relation to teaching mainstream pupils and pupils with developmental disabilities. The starting assumption of this analysis is that teacher professional development is largely dependent upon teachers’ beliefs about various facets of their professional work. These concepts strongly influence the way that teachers teach and the way that they develop as teachers. The participants in the research are 314 student teachers at the Faculty of Teacher Education of the University of Zagreb who are being prepared to teach in lower grades of primary school. The beliefs were explored using a metaphor technique derived from cognitive theory of metaphor. The differences between beliefs about the perceived teacher role in general, and the perceived teacher role in the education of pupils with developmental disabilities were analysed. The results indicate that the dominant belief about the teacher’s role in teaching mainstream pupils is of the teacher as a transmitter of knowledge, while the findings regarding the dominant belief about the teacher’s role in teaching pupils with developmental difficulties appeared to be self-cantered orientation. No differences were found between student teachers at different study levels. The findings are discussed in the light of the curriculum of initial teacher education.     

Validity of Holland’s theory in adolescence: evidence from a Slovak sample

The underlying calculus assumption of Holland’s theory was tested in two samples of primary school students (N₁ = 400 and N₂ = 250) with an average age of 13.86 and 14.14 years, respectively. Both exploratory and confirmatory multidimensional scaling and Hubert and Arabie’s randomization test of hypothesized order relations were calculated. The circular spatial arrangement of RIASEC types was not confirmed in either of the two samples. The study discusses possible causes of the inappropriateness of using Holland’s model in an adolescent sample.

     

Social inequity and educational expansion in Slovenia

The study examines the relationship between social inequalities (stratificational, gender and other disparities) and schooling, including academic attainment, longitudinally, in Slovenia. The issue is indicated most clearly at the tertiary education level. The basic finding is the parallel between educational expansion and the diminution of social inequalities as measured by standard parameters. This was particularly evident in the 1990s. Inequalities are measured in terms of gender, parental education and occupation. The impact of parental education proves to be an indicative, observable and longitudinally comparative measure. Parental occupational status is also clearly linked to their children’s scholastic attainment, although there are difficulties in the formation of occupational strata. Further considered is the impact of school reforms over a lengthier period of time; there was not, however, any detectable impact. School and welfare policies, even financing, have little significance. There are clear indications that social disparities at school are continually regenerated, despite the decline established by standard measures. New forms of social disparities appear, through which the privileged ensure the continuation of privilege.     

Empowering learners with personalised learning approaches? Agency,equity and transparency in the context of learning analytics

Abstract

The emergence of personalised data technologies such as learning analytics is framed as a solution to manage the needs of higher education student populations that are growing ever more diverse and larger in size. However, the current approach to learning analytics presents tensions between increasing student agency in making learning-related decisions and ‘datafying’ students in the process of collecting, analysing and interpreting data. This article presents a study that explores staff and student experience of agency, equity and transparency in existing data practices and expectations towards learning analytics in a UK university. The results show a number of intertwined factors that have contributed to the tensions between enhancing a learner’s control of their studies and, at the same time, diminishing their autonomy as an active agent in the process of learning analytics. This article argues that learner empowerment should not be automatically assumed to have taken place as part of the adoption of learning analytics. Instead, the interwoven power relationships in a complex educational system and the interactions between humans and machines need to be taken into consideration when presenting learning analytics as an equitable process to enhance student agency and educational equity.
