Mini-languages are a visually intuitive, simple and powerful way to introduce students to programming. They are a good foundation for general computer science instruction, provide insight into programming for the general population, and teach algorithmic thinking. The goal of the paper is to provide an extensive review of the mini-language approach to teaching programming. For different audiences and in different countries, the authors have extensive experience in design and application of mini-languages. We outline the problems that motivate the application of this approach, present a brief history, review several existing mini-languages, and provide discussion of lessons learned. In particular, we discuss how to choose a mini-language for a particular group of students and list some requirements for a successful application of a mini- language. We conclude with a discussion of possible future directions of the mini-language approach development 相似文献

Based on a social constructivist theoretical framework, this research study examines how the design of proinclusive educational policies and the general public construct the Roma students and parents in Slovakia. For this purpose, data from two selected educational policies and five focus groups conducted in five regions in Slovakia were analyzed. The findings demonstrate that the Roma are constructed negatively as irresponsible dependents and deviants not valuing education and incapable of making wise decisions about their lives. These findings can be considered relevant for policy formulation processes because proinclusive policies may sabotage their own goals if negative social constructions of a certain societal group are embedded in them. 相似文献

The concept of distributed leadership has been widely accepted and scrutinised in research and practice since the beginning of the new millennium. Nonetheless, there is a lack of academic research on how school staff members perceive the term and to what extent they are willing to employ it as part of their daily practices. This article aims to explore these understandings and attitudes in two public primary schools – one in New South Wales (Australia) and one in Slovakia – whilst using qualitative research methods based on semi-structured interviews with staff members. The findings of this study reveal that participants often present very contradictory attitudes towards employing distributed leadership in practice. On the one hand, they require maximising the processes of distributed leadership and, on the other hand, they welcome various instances of solo/autocratic leadership practices by the principal. They also often conflated the concepts of distributed leadership and democratic leadership. In addition, the article discusses how wider social and political context may shape these perceptions and attitudes towards distributed leadership. 相似文献

Worldwide, a tendency is visible in which upper secondary science curricula are innovated in the direction of context‐based education. Crucial to these innovations is the way teachers interact with newly developed teaching materials and implement them in classroom practice. The focus of our research is to identify characteristics of the interaction between innovative context‐based materials and teachers that hinder or facilitate classroom implementation as intended by the designers. Four cases of classroom implementation by four experienced teachers with different degrees of experiences in context‐based education, all implementing ‘Chemie im Kontext’ (CHiK) teaching materials, were carried out using a previously developed framework for analysis. It was found that a crucial aspect of CHiK, that of taking students' questions and using them as an orientation as the ‘focal event’ for the following lessons, was difficult to implement. The employed contexts are too general and broad to be effectively applicable as a setting in which activities such as students developing their own ideas and exploring them logically take place. Therefore, it is recommended that extensive teacher professionalization is required on this aspect to show teachers its value and to increase their repertoire of necessary teaching activities. 相似文献

Interactive Whiteboards (IWBs) are a relatively new, but increasingly more common, tool in the classrooms of Flemish Secondary schools. This paper reports on research which attempted to map not only the amount of IWB use in Flemish secondary schools but, perhaps more importantly, to assess how they are used and the progress of teachers in developing their IWB skills in the classroom. An online quantitative survey was conducted, based on a detailed IWB transition framework. The survey (n?=?433) identified the distribution and usage levels of the IWB by teachers in Flemish Secondary Education. The results show that the distribution of IWBs is affected by the educational network to which a teacher belongs. In terms of the level of IWB use, teachers classified themselves predominantly in the first two stages of the transition framework (Black/Whiteboard Substitute and Apprentice use). This would suggest that teachers in Flemish Secondary Education have been initiated (in a technological sense) in using the IWB and are beginning to initiate (in a pedagogic sense) wider usage, including incorporating pupil use of the IWB. In this process, however, teachers appeared to be more confident in technical use of the ICT skills, but less confident in developing new pedagogic approaches which may exploit the full potential of the IWB. 相似文献

The fall of Communist regime in 1989 and the dissolution of Czechoslovakia in 1993 significantly affected the educational system of today's Slovakia. As a sovereign state, Slovakia has ratified the Convention on the Rights of Persons with Disabilities obliging its signatories to practise ‘inclusive education’. This article explores the current educational policies of the Slovak Republic in light of this obligation. Using the official statistical data the article argues that the current state educational policies have not succeeded in meeting the objective of practising inclusive education, as the proportion of students educated in segregated special educational provisions has been consistently rising over the last decade. This article attempts to identify particular aspects of the current educational policies which might have contributed to this phenomenon. 相似文献

In this study the impact of quantum therapy on meat quality of slaughtered pigs was investigated. For this purpose the pigs
were treated with different doses of magnet-infrared-laser (MIL) radiation. Animals were divided into four groups according
to radiation doses (4096, 512, and 64 Hz, and control without application), which were applied in the lumbar area of musculus longissimus dorsi (loin) at various time intervals prior to the slaughter (14 d, 24 h, and 1 h). Animals were slaughtered and the meat quality
was evaluated by determining of pH value (1, 3, and 24 h post slaughter), drip loss, colour, and lactic acid and phosphoric
acid amounts. MIL therapy can be used in various fields of veterinary medicine as are surgery and orthopaedics, internal medicine,
dentistry, pulmonology, gastroenterology, gynaecology, urology, nephrology, and dermatology. The results achieved showed that
MIL radiation used in a short period before slaughter (1 h) can cause a change in the meat quality, as reflected by the non-standard
development of pH values, increases in drip loss, and changes of meat colour. 相似文献
