An ordinary moonlighting activity? Determinants of the provision of private tutoring by Czech schoolteachers

Teacher moonlighting (teachers working other jobs in addition to teaching) may have positive as well as negative implications. In the context of post-socialist countries, the provision of private tutoring is one of the common forms of teacher moonlighting. The aim of the paper is to analyse the prevalence and factors that are associated with a) having a paid job in addition to one’s regular teaching obligations; b) provision of private tutoring among teachers. Results are drawn from a representative sample of 494 Czech teachers of academic school subjects in lower secondary schools who responded to an online questionnaire survey. Male teachers working part-time, with shorter professional experience, higher household financial burden and lower satisfaction with teacher salaries were more likely to moonlight. The provision of private tutoring was only associated with shorter professional experience and the teaching of core subjects, suggesting that Czech teachers’ motivation to provide private tutoring is currently not primarily financial.     

Teachers’ self-efficacy and intercultural classroom practices in diverse classroom contexts: A cross-national comparison

This cross-national study provides new insights in teacher efficacy in today’s culturally diverse classrooms using survey data of 269 early childhood and primary school teachers in England, Italy, the Netherlands and Poland. Teacher efficacy can be viewed as a two dimensional concept in which both general beliefs are measured alongside (diversity-related) domain-specific beliefs. These beliefs are related to the cultural classroom context and the use of intercultural classroom practices. Our results indicate that policies and professional development targeted at the reciprocal relation between diversity-related efficacy and practices are important when preparing teachers for working in diverse classroom contexts.     

Individual and cultural factors in teachers’ attitudes towards inclusion: A meta-analysis

The success of inclusive education is dependent upon classroom teachers implementing adaptations for children with disabilities. Given that willingness to make such adaptations is influenced by teacher attitudes, the current study examined teachers’ attitudes towards inclusive education through a meta-analysis of 64 samples that were found via a systematic literature search. The results indicated that teachers hold a positive attitude towards inclusion of children with disabilities in mainstream schools and that these attitudes are moderated by an interplay of cultural and demographical factors. The findings offer a renewed basis for intervention research into improving educational opportunities for children around the world.

Performative technologies and teacher subjectivities: A conceptual framework

Critical educational literature suggests that an increased reliance upon performative technologies is currently transforming the very foundations from which teacher subjectivities are constructed. Arguably though, the number of studies pointing to this risk or tendency is considerably larger than the ones theorising why this should be the case. Further, in those cases where the relationship between performative technologies and teacher subjectivities is theorised, the psychological mechanisms that the technologies appeal to are seldom brought to the fore. Based on this, the purpose of this article is to theorise the psychological mechanisms that performative technologies appeal to and work through, by means of identifying, systematising and elaborating extant understandings of such mechanisms in the critical educational literature. The results are presented in the form of a conceptual framework (referred to as the CMIS-framework) which suggests that one and the same performative technology may play many different roles, where each such role appeals to and works through a particular psychological mechanism. Importantly, depending on the type of psychological mechanism that is appealed to, the CMIS-framework suggests that this will lead to teachers (un)consciously conducting particular forms of subjectivising work upon themselves, here referred to as compliance, mirroring, identification and self-realisation (CMIS).     

Professional knowledge or motivation? Investigating the role of teachers’ expertise on the quality of technology-enhanced lesson plans

In an expertise study with 94 mathematics teachers varying in their relative teacher expertise (i.e., student teachers, trainee teachers, in-service teachers), we examined effects of teachers' professional knowledge and motivational beliefs on their ability to integrate technology within a lesson plan scenario. Therefore, we assessed teachers' professional knowledge (i.e., content knowledge, pedagogical content knowledge, technological knowledge), and their motivational beliefs (i.e., self-efficacy, utility-value). Furthermore, teachers were asked to develop a lesson plan for introducing the Pythagorean theorem to secondary students. Lesson plans by advanced teachers (i.e., trainee teachers, in-service teachers) comprised higher levels of instructional quality and technology exploitation than the ones of novice teachers (i.e., pre-service teachers). The effect of expertise was mediated by teachers' perceived utility-value of educational technology, but not by their professional knowledge. These findings suggest that teachers’ motivational beliefs play a crucial role for effectively applying technology in mathematics instruction.     

Medieval and renaissance glass technology in Valdelsa (Florence). Part 1: raw materials, sands and non-vitreous finds

A significant number of archaeological finds of the 13th–16th century from the Tuscan sites of Germagnana and Gambassi in Valdelsa—FI, was studied by different physico-chemical investigations (SEM–EDS, ICP, Mössbauer spectroscopy, XRD, XRF, TG-DTA) in order to contribute to clarify the production methodology and the pre-industrial glass manufacture technology. The studied samples are mainly non-vitreous finds as production waste, refractory materials, crucibles and raw materials; also vitreous finds as frits, skims, glasses (glass masses, glass working waste and finished products) have been taken into consideration. The obtained petrographic and physico-chemical data strongly suggest that both Gambassi and Germagnana glass manufactures were strictly connected with the sources of vitrifiable materials, situated in Tuscan sand quarries. In particular a comparison between sands from the neighbouring quarries and appropriate finds of the two archaeological sites evidences that the employed vitrifiable materials possibly belong to La Casina La Cava resort. The archaeological classification, based on macroscopic observation and stratigraphic position, was compared and verified with the scientific classification of the examined finds of Germagnana and Gambassi sites based on their composition, morphology and physico-chemical properties.
