The Impact

Exploring chemistry through its presence in the literature in general, and poetry in particular, may increase students' curiosity, may enhance several basic skills, such as writing, reading comprehension and argumentative skills, as well as may improve the understanding of the chemistry topics covered. Nevertheless, the pedagogical potential of the link between poetry and chemistry has not yet been fully explored in school. This article describes a study during which a teaching strategy was used with pre-university students of introductory chemistry in order to explore the topics atomic radius and ionization energy by resorting to a poem about alkali metals. The study resulted in new poems and cartoons of chemical elements created by the students, which, together with the results of a questionnaire survey, were positive indicators of the impact of poetry in the motivation and learning of the chemistry topics explored. While the students showed some difficulties interpreting the poem, they considered that teaching chemistry with poetry is a motivating strategy that should be used more often, and that it enhances the students' engagement in the construction of significant learning.

The paper presents the results of a study of the microstructure, chemical composition, microhardness and corrosion resistance of Cr-B coatings produced on Vanadis 6 tool steel. In this study, chromium and boron were added to the steel surface using a laser alloying process. The main purpose of the study was to determine the impact of those chemical elements on surface properties. Chromium and boron as well as their mixtures were prepared in various proportions and then were applied on steel substrate in the form of precoat of 100 µm thickness. Depending on the type of precoat used and laser processing parameters, changes in microstructure and properties were observed. Coatings produced using precoat containing chromium and boron mixture were characterized by high microhardness (900 HV0.05–1300 HV0.005) while maintaining good corrosion resistance. It was also found that too low laser beam power contributed to the formation of cracks and porosity.

The Impact

The COVID-19 pandemic and its restrictions strongly affect the higher education community and require diverse teaching strategies. We designed a course where we combined online teaching with independently conducted ecological data collections by students using a “citizen science” approach. The aim was to analyze the impact of urbanization on biota by comparing urban and rural grasslands. Seventy-five students successfully conducted the data collections and the results provide evidence for prevailing negative effects of urbanization. Individual numbers of ground-dwelling invertebrates (−25%) and pollinating insects (−33%) were generally lower in urban sites. Moreover, animal and seed predation were reduced in urban grasslands, indicating the potential of urbanization to alter ecosystem functions. Despite the general limitations of online teaching and citizen science approaches, outcomes of this course showed this combination can be a useful teaching strategy, which is why this approach could be used to more actively involve students in scientific research.

Purpose: This review explored trends in studies on learning outcomes in nursing education using gamification, to provide directions for future research.Methods: This scoping review was conducted according to the Joanna Briggs Institute's guidelines. The literature search date was February 1, 2021.Results: Thirty-two studies were included. The largest proportion of studies were quantitative descriptive studies, including qualitative mixed methods (34.4%). More studies applied gamification in practical classes (53.1%) than in theoretical classes. Virtual simulation games (37.9%) and simple quiz games (34.4%) were most often used. Commonly used gamification elements included scores/points, feedback, badges, countdowns, challenges, competitions, and levels. Two themes emerged regarding the impact of gamification on learning: learners’ experiences and achievement outcomes with cognitive, affective, and psychomotor subthemes. Nursing education using gamification improved engagement, motivation, and learning achievement. However, there was less evidence for affective and psychomotor outcomes than for cognitive outcomes.Conclusion: Gamification can be an effective educational strategy if educator's have sufficient understanding and readiness and appropriate gamification elements are applied to nursing education. Further research should investigate knowledge retention in the cognitive domain, collaboration and empathy in the affective domain, and the improvement of nursing skills using new technologies in the psychomotor domain.
