In the last few decades, technology has advanced in multiple fields, including Education. Some of its benefits include improving student performance and motivation, fostering active learning and tracking student progress. As a "new learning generation" is around, profound changes to the role and function of both teachers and students are particularly vital, so active, cooperative and participative methodologies of learning must be privileged. Given that most higher education students are technology savvy and very receptive to the integration of Web 2.0 tools in class, the teachers involved in this study began using Kahoot! in their classes as an alternative teaching methodology. The participants in the study are undergraduate students from a Portuguese higher education institution and encompassed the curricular units of Statistical Analysis and English. The aim of the study is to investigate students' perceptions of how Kahoot! can be used as a tool for testing new vocabulary, reviewing class content or designing warm-up activities. A quantitative survey is being conducted to gather information about students' insights on the use of Kahoot!. Similar studies have shown that students are generally receptive to the use of this tool and find it useful to increase their motivation.
The use of different registers to represent mathematical concepts enhances understanding. For example, rational numbers can assume pictorial, symbolic and natural language representations and this kind of change improves learning. Based on these assumptions, a teaching experiment for the learning of rational numbers by 2nd grade students was conducted, so as to allow for an understanding of how semiotic representations contribute to the learning of rational numbers, particularly with concern to unit fractions. Using a qualitative methodology and a content analysis of the students' written productions, the study shows a greater use of the pictorial representation register compared to the other types. Students' main difficulties in learning rational numbers are related to the pictorial representation of unit fractions and to an understanding of the concept of fraction itself. Some of these difficulties result from errors such as the misrepresentation of unit fractions in the case of the pictorial register, the association of the concept "half" with multiple unit fractions, the absence of the fraction bar when it comes to the symbolic register, the use of everyday terms to represent fractions when students rely on the natural language register, and the misrepresentation of rational numbers when the graphic register is used.
Until the emergence of the COVID-19 pandemic, tourism was one of the sectors with the greatest growth potential on a global scale. It is now highlighted as one of the hardest hit sectors in economic terms and requires strategic recovery capacity coupled with technological innovation. Technology and innovation could provide a strong contribution to the development of tourism by integrating knowledge about tourism products, services and experiences and the new needs and behaviours of consumers. This study analysed the scientific productions on technological innovation in the tourism sector using literature review and bibliometric analysis techniques, with data collected from the main databases of international relevance, Web of Science and Scopus. This study presents the mapping and cluster structures for the trends and dynamics of the investigations on the discovered research themes using the VOSviewer software. The results indicate that research related to innovation and technology in tourism has evolved in recent years, as well as highlighting the main areas of activity and presenting contributions to possible future lines of research.
The Heart of Redness comprises two narrative strands: one which is set only four years after the first democratic elections in South Africa and one that explores the 1856–57 “Cattle Killing Movement” and discloses the early encounters between the Xhosa and the British colonizers. Retrieving the past episode originated in the visions of prophetess Nongqawuse and aligning it with the contemporary discussion surrounding issues of economic and social development raised by the proposal of a tourism project for the village of Qolorha, Mda successfully articulates the complex elements that have marked past and present South African culture and society. In Mda’s novel, the village of Qolorha and the character of Nongqawuse are released from their negative association with one of the most dramatic episodes in the history of the Xhosa and transformed into a tourist attraction that has the potential to contribute to the sustainable development of the local population. Mda’s rescue of Qolorha from the threat of massified tourism, and his recovery of Nongqawuse as a meaningful character for the history of the Xhosa, emphasize the importance of alternative development models and the relevance of revising biased historical narratives that often served manipulative objectives.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
