Self-Assessment of Students of Geography Education and Primary Social and Science Teaching towards the Use of Digital (Geo-) Media for Written and Oral Argumentation

by Sebastian Wolff-Seidel and Alexandra Budke

Eur. J. Investig. Health Psychol. Educ. 2022, 12(6), 516-533; https://doi.org/10.3390/ejihpe12060038 - 25 May 2022

Abstract

This article discusses possible challenges and potentials in the use of digital geomedia in the context of written and oral argumentation in higher education by examining the perspectives of students and lecturers, especially for the subjects of geography in general and primary school science. To this end, potentials and challenges, as well as competences that have to be promoted among pupils and students in dealing with digital geomedia in the context of written and oral argumentation are first discussed. In the following, we present the results of a mixed methods approach in which we surveyed student teachers with a questionnaire (n = 150) on the one hand and, on the other hand, reflected their view of the issue by analysing qualitative expert interviews (n = 17) with lecturers who teach at the same universities in the corresponding degree programmes. In this way we contextualise the student’s self-assessment in the respective location’s teacher training. Our results show that there is a high degree of commonality between lecturers and students with regard to the importance of argumentation with digital geomedia. At the same time, the assessment of the students’ abilities differs greatly; most students feel capable of dealing with these topics, while lecturers see deficits here. Full article

Abstract

In situ observations and laboratory experiments showed that slow deformation waves widely exist in geomedia under loading conditions. Slow deformation waves’ behavior exhibits some similarities in media ranging from the scale as large as the Earth’s crust to the scale as small as the laboratory test samples. However, the mechanism underlying their generation has not been clarified yet. In this research an experimental study was performed on small-scale red sandstone samples subjected to uniaxial compression at the displacement rates of 0.1, 0.5, and 1 mm/min. Slow deformation waves under different loading rates were analyzed by speckle photography for microscopic characterization combined with the digital image correlation (DIC) technique. The Luders deformation bands were predominantly observed in the flow channels formed at the stage of macro-elastic deformation. The spatial-temporal heterogeneity of the rock sample surface was quantified, and the deformation waves’ propagation velocities under different loading rates were obtained. The linear relationship between the propagation velocities of slow deformation waves and the loading rates was determined. The research findings shed some new light on the evolutionary characteristics of the slow deformation waves. Full article

Abstract

Viewing the Earth from above has fascinated people at least since the Apollo mission in the 1960s. Today, satellite images have made their way into the news and media, but the potential of using satellite images in the classroom has not yet been exhausted. Teachers often lack the technical knowledge of Earth observation (EO) or the technical requirements in schools. The Geo:spektiv e-learning platform used provides the opportunity to integrate EO into curricula as well as current environmental- and space-relevant topics. This study analyses the driving forces that determine the motivation of students and which factors contribute to the success of an e-learning platform. The basis for this study is a Geo:spektiv module about the endangered rainforest, established at an out-of-school learning place and designed for students in secondary education. A survey of 281 students on their motivation and learning behavior showed, that in addition to the topic and level of difficulty tailored to the students’ needs, the design of the modules, simple navigation, and the use of multimedia content are vital. Despite the small sampling size and restricted geographical location of sample selection, the results of this study can contribute to better integration of digital geo-media in school lessons.
