Generally, oral storytelling is an ancient art of telling stories that has been passed down from generation to generation while digital storytelling incorporates technology which consists of various multimedia modes such as graphics, audio, texts, videos and animations. This paper analyses the differences between the two strategies by discussing their differences in four aspects: (1) the use of technology, (2) the role of storyteller, (3) the approach of process and product, and (4) the engagement of audience. The analysis aims to create awareness among academicians about these differences and highlight that digital storytelling is the combination of both the art of storytelling and digital story. Then, this paper provides a critical review of empirical studies on the potentials of using digital storytelling in teaching and learning for education. The results have shown that the use of digital storytelling is not only beneficial in developing the teachers' content, pedagogical and technological knowledge, but also in enhancing their students' learning as it increases their understanding of content and caters for their multiple intelligence. This study suggests the implementation of digital storytelling in teaching and learning in the classroom and future directions for research are suggested.
Electrical Capacitance Tomography (ECT) detects changes in the distribution of transparency in enclosed areas or pipes. Until now, various methods have been used to determine the optimum ECT sensor for a particular application. Some important parameters that affect the sensitivity of the sensor cannot be ignored. Design factors discussed in this paper study the needs in industry by producing the best image, without affecting the operation of the process. From previous studies many parameters influence the quality and effectiveness of an ECT sensor. The parameters that play important roles in ECT sensor design include the thickness and type of material in the pipe wall between the electrodes and the sensing zone, the thickness and material of the pipe wall separating the electrodes and the screen, the size of the electrodes, the guarding used, example radial guards or plane axial guards, and whether end guards are used. Other matters of concern regarding the dimension and the distance between the electrodes with guardians it is important design factor. Electrodes positioned either inside or outside the vessel will affect the cost factor design to the type of system to be used. This overview of the study is a basic guide for the essential requirements for an ECT sensor system design.
This study aims to investigate the perception of undergraduate students about their lecturers’ behaviours in their learning environment. Behaviour is the explanation of observable outcomes and interaction between students and instructors. Behaviour can be positive, negative, effective or ineffective, and the way in which lecturers behave with their students in the learning environment may affect their learning experience and motivation. A Quantitative research design was employed in conducting the study. A questionnaire with 27 items was used to collect data from 140 randomly selected respondents from Takhar University, Afghanistan. SPSS version 25.0 was used to analyze the data. Descriptive statistics and inferential statistics, i.e., Independent Samples t-test and One-Way ANOVA were employed in data analysis. The findings indicate that the students had a positive perception about their lecturers’ behaviours in the learning environment. The study also revealed that there did not appear to be any statistically significant differences in participants’ responses by their gender or the classes they took. The findings of the current study may lead to policies with regard to lecturers’ behaviours and inform instructors to improve classroom practices in the learning environment.
Purpose The sudden pandemic of COVID-19 has caused disruptive innovation in all areas of business including education. Despite the educators’ and students’ acceptance and readiness in the new normal, the traditional face-to-face (FTF) public speaking has been shifted to online courses to suit the current needs. This study aims to examine whether there were differences between online and FTF pubic speaking in the students’ anxiety level, speech performance, as well as their perceptions of the challenges in the implementation of online public speaking courses as a potential to disruptive innovation. Design/methodology/approach This pilot study was a mixed method research that involved a purposive sampling of two groups of 39 students in higher education. The instruments used were questionnaires of self-report anxiety, speech performance test and observation. Findings The findings show that the students preferred the traditional FTF rather than the online mode for public speaking courses. The challenges of internet connection and the lack of a live audience were their main concerns in online public speaking. It also provides a potential for disruptive innovation that could take into consideration of a live audience in university online courses. Originality/value This study provides the potential of public speaking course as a disruptive innovation. This brings implications for the innovators, marketers and educators to think of the online courses/programmes that can be best implemented while embracing the changes and the new normal of COVID-19 brings for student learning.
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.
