Game Maker is widely used in UK secondary schools, yet under-researched in that context. This paper presents the findings of a qualitative case study that explores how authoring computer games using Game Maker can support the learning of basic programming concepts in a mainstream UK secondary setting.  The research draws on the learning theory of constructionism, which asserts the importance of pupils using computers as ‘building material’ to create digital artefacts (Papert, 1980; Harel and Papert, 1991), and considers the extent to which a constructionist approach is suitable for introducing basic programming concepts within a contemporary, game authoring context.  The research was conducted in a high achieving comprehensive school in South East England. Twenty-two pupils (12 boys; 10 girls; 13-14 years old) completed a unit of work in computer game authoring over an eight-week (16 x 50 minute lessons) period. In planning and developing their games, they worked in self-selected pairs, apart from two pupils (one boy and one girl) who worked alone, by choice. Nine of the ten pairs were the same gender. Data were collected in planning documents, journals and the games pupils made, in recordings of their working conversations, and in pair, group and artefact-based interviews. Findings indicate that as well as learning some basic programming concepts, pupils enjoyed the constructionist-designed activity, demonstrated positive attitudes to their work, and felt a sense of achievement in creating a complex artefact that had personal and cultural significance for them. However, the findings also suggest that the constructionist approach adopted in the research did not effectively support the learning of programming concepts for all pupils. This research arises out of a perceived need to develop accessible, extended units of work to implement aspects of the Computing curriculum in England. It suggests that using Game Maker may offer a viable entry, and identifies the programming concepts and practices which pupils encountered, the difficulties they experienced, and the errors they made when authoring computer games. It also offers recommendations to increase the readiness with which students engage with key programming concepts and practices when using this visual programming software. In so doing it makes a practical contribution to the field of qualitative research in secondary computing education.

Abstract Background Culicoides biting midges (Diptera: Ceratopogonidae) are biological vectors of internationally important arboviruses and inflict biting nuisance on humans, companion animals and livestock. In temperate regions, transmission of arboviruses is limited by temperature thresholds, in both replication and dissemination of arboviruses within the vector and in the flight activity of adult Culicoides. This study aims to determine the cold-temperature thresholds for flight activity of Culicoides from the UK under laboratory conditions. Methods Over 18,000 Culicoides adults were collected from the field using 4 W down-draught miniature ultraviolet Centers for Disease Control traps. Populations of Culicoides were sampled at three different geographical locations within the UK during the summer months and again in the autumn at one geographical location. Activity at constant temperatures was assessed using a bioassay that detected movement of adult Culicoides towards an ultraviolet light source over a 24-h period. Results The proportion of active adult Culicoides increased with temperature but cold temperature thresholds for activity varied significantly according to collection season and location. Populations dominated by the subgenus Avaritia collected in South East England had a lower activity threshold temperature in the autumn (4 °C) compared with populations collected in the summer (10 °C). Within the subgenus Avaritia, Culicoides scoticus was significantly more active across all temperatures tested than Culicoides obsoletus within the experimental setup. Populations of Culicoides impunctatus collected in the North East of England were only active once temperatures reached 14 °C. Preliminary data suggested flight activity of the subgenus Avaritia does not differ between populations in South East England and those in the Scottish Borders. Conclusions These findings demonstrate seasonal changes in temperature thresholds for flight and across different populations of Culicoides. These data, alongside that defining thresholds for virus replication within Culicoides, provide a primary tool for risk assessment of arbovirus transmission in temperate regions. In addition, the study also provides a comparison with thermal limits derived directly from light-suction trapping data, which is currently used as the main method to define adult Culicoides activity during surveillance.
