This study investigated young children’s computational thinking (CT) development by integrating ScratchJr into a programming curriculum. Twelve third graders (six males and six females) voluntarily participated in an experiment-based computer class conducted at a public elementary school in Taiwan. This study adopted a case study methodology to investigate research questions in one specific case (8-week CT educational training). A one-group quasi-experimental pretest and posttest design with the support of qualitative observation was used to examine four research topics: CT competence progress, programming behaviors in a CT framework, factors influencing CT competence, and learning responses to CT training. The quantitative results indicated that students immersing in weekly programming projects significantly improved in terms of their CT competence, which was mostly retained 1 month after completion of the class. The programming behaviors indicated that students’ CT concepts (sequence, event, and parallelism) and practice (testing and debugging as well as reusing and remixing) significantly improved. Moreover, parents’ active involvement in take-home assignments influenced students’ long-term CT competence retention. The qualitative results indicated that students enjoyed using tablet computers to learn ScratchJr programming and demonstrated various leaning behaviors in a three-stage instructional design model.

The present study is part of a research about computational thinking and tangible robotics. A robot in development in Portugal, MI-GO robot, is part of the basis of this research. The objective is to determine the attitude of young students concerning tangible robots and to observe in what measure they contribute to the development of their STEM skills. On the other hand, it also aims to know what are the opinions of educators, teachers, and researchers concerning MI-GO's characteristics and what is their value, adequacy and suitability for the educational grades of young learners (from 5 to 10). The study consists on a qualitative approach based in a case study methodology, using the techniques of questionnaire and observation. At first the data reveal a clear adhesion to the robot and tangible programming by learners, and the researchers that analyzed the device consider it was a very adequate one and presented several suggestions to improve it.

Advances in applied sport psychology will require the application of experimental, quasi-experimental, and nonexperimental research methodologies. The case study has stimulated important discoveries in many areas of psychology, although its limitations for drawing causal inferences are widely acknowledged. Case studies vary markedly in their design and methodology, however, and these differences dictate the extent to which alternative explanations can be ruled out on procedural or empirical grounds. The present article discusses design considerations that influence the construct validity, internal and external validity, and reliability of case reports. The application of techniques such as pattern matching, time-series analysis, and goal-attainment scaling to case study methodology is also described. Finally, guidelines for planning and reporting case studies in a manner that enhances their scientific and practical contributions are discussed.

This paper shows the principal features of merger control in selected transition economies of Central and Eastern Europe (CEE), namely Hungary, Romania and Slovenia, by applying case study methodology. The presented findings are based on the analysis of Hungarian, Romanian and Slovenian competition law and merger rulings reached by the Competition Offices of these countries. A substantial part of the conclusions is drawn from a sample of 42 merger applications processed by the Office of Economic Competition of Hungary between 1994 and 2000. The results of empirical analysis demonstrate the considerable flexibility of merger control in the studied countries, its orientation towards the future of domestic markets and a close link with industrial policy. The paper also highlights the areas of interdependence of competition policy and transition and argues that merger control in the studied CEE countries may be regarded as currently adequate to the requirements imposed by transition.

Background: Wine tourism is one of the tourism components adopted as part of Portugal’s strategy due to its eminence as a wine producer. Such strategy has received great prominence in recent years and aims to promote regional development from an economic, social, cultural and environmental perspective. The aim of this study was to understand the entrepreneur profile in this sector. Methods: The study uses a qualitative, case study methodology with data analysis and triangulation. In this study, a literature review of scientific studies was carried out on the scientific knowledge in the area of study from a critical perspective and an interview was conducted where qualitative data were collected. Results and Discussion: The entrepreneurs have shown the following characteristics: initiative, innovation capability, optimism, creativity, creative energy, tenacity, selfconfidence, capability for long term involvement with the project, and learning capacity. Conclusion: The study shows that most entrepreneurs state that they have established partnerships with other companies, particularly with restaurants, catering businesses, hotel units, tourism companies and companies that organize tours. This is one of the factors of economic importance recognized by another study which enables increased prominence of the company and widens the value of wine tourism.

This paper reports the findings of a small-scale study seeking to investigate how student teachers, within a three-year undergraduate programme, understand feedback. Feedback has been central to debates and discussion in the assessment literature in recent years. Hence, in this paper, feedback is positioned within the often-contradictory discourses of assessment, including perspectives on student and teacher feedback. The study focused on two first year undergraduate student teachers at a small university in England and considered the relationships between their understanding of feedback as a student, their understanding of feedback as an emerging teacher, and the key influences shaping these understandings. A phenomenological case study methodology was employed with interviews as the prime method of data collection. Themes emerged as part of an Nvivo analysis, including emotional responses, relationships and dialogue, all of which appear to have impacted on the students’ conceptual understanding of feedback as indelibly shaped by its interpersonal and affective, rather than purely cognitive or ideational, dimensions. The paper therefore seeks to contribute to the wider feedback discourse by offering an analysis of empirical data. Although situated within English teacher education, there are tentative conclusions that are applicable to international teacher education and as well as higher education more generally.

The target 12.3 of the 2030 Agenda by the United Nations (UN) calls for halving per capita global food loss and waste. In this regard, the Food & Drink industry (F&D) could play a crucial role in reducing food waste and improving food safety by adopting healthy and eco-innovation packaging. Thus, this paper aims to investigate the F&D manufacturers’ willingness to invest in packaging innovations, such as active, intelligent, and compostable ones to achieve the UN target. In order to reach the stated objective, a multiple case study methodology was developed and administered to a sample of Italian micro and small-medium entrepreneurs located in the Apulia region. Results show that many firms were aware of their need for packaging innovation and of the available technological opportunity. However, only the F&D manufacturers who showed a Real demand, according to a taxonomy approach which also considers the Potential and Latent demand for the innovation, were effectively prompt to invest. Finally, most of the interviewed manufacturers were willing to invest in at least one packaging innovation, choosing mainly between the active packaging and the compostable one.

The review of environmental impact statements (EIS), despite its relevance to impact assessment effectiveness, has received scarce scholarly attention. Few studies have gone beyond the realm of regulatory evaluations to understand the managerial meanders of the review process. This study evaluated the responsibilities, procedures, information inputs, and scope of EIS reviews within two environmental authorities: APA (Portuguese Environment Agency), in Portugal, and SEMAD (State Secretariat for Environment and Sustainable Development), in the Brazilian state of Minas Gerais. Based on a qualitative multiple-case study methodology informed by participant observation, unstructured interviews, and content analysis of 12 EIS review reports, the study provided what is arguably one of the most detailed characterizations of EIS review to date. While following similar institutional arrangements and broad procedural steps, the EIS review has important differences in APA and SEMAD. Overall, the Portuguese agency was found to have a more structured, participative, interdisciplinary, detailed, and grounded review, thus meeting some of the good practices often cited in the literature. The EIS review reports prepared by APA reviewers were also found to provide a profoundly more complete and transparent account of the review process. The details of the review process revealed in the article can affect perceptions around the legitimacy and reliability of reviewers’ recommendations.
