The motion of a cylindrically or spherically symmetric body on an accelerated treadmill, inclined of an angle [theta] with respect to the horizontal, is described by means of Newtonian mechanics. By assuming that the conveyor belt has an acceleration "a[subscript O][superscript ']", not necessarily constant, and that the body rolls on…

The pandemic caused by COVID-19 has induced health emergencies followed by changes in social life and education. The transition to online teaching might be harder or easier depending on the situation in a particular country, as well as on the curriculum of teaching subjects and teaching methods that are used. In this paper the methods used in…

The sudden transition to online teaching due to the pandemic in spring 2020 provided us the opportunity to experience firsthand the challenges involved in delivering labs online. After learning that our introductory lab courses would be taught online fall 2020 and spring 2021, which involve over 2200 students, the decision was made to invest…

A complex research project was translated into a Course-based Undergraduate Research Experience (CURE), which was implemented in sections of an introductory Cell and Molecular Biology laboratory course. The research laboratory generated an engineered plant line producing a growth-inhibiting, lipid-derived plant hormone and mutagenized this line.…

In this article, the authors share a unique science, technology, engineering and math (STEM) online field trip structure developed for high school students. The ninth-, tenth-, and eleventh-grade students who participated in the virtual field trips were from multiple high schools. This article focuses on two virtual trips that the authors…

Chaotic phenomena are not part of standard curricula, although this subject offers several interesting aspects which can help students better understand basic features of science. A central observation is that even simple physical systems, if chaotic, are unpredictable, just like the weather. We present the principles applied when developing a…

Although learning about Nature of Science (NOS) promotes a variety of important outcomes, teachers often lack suitable activities for younger students to effectively address NOS. In this article I elaborate on an NOS activity developed for a teacher professionalisation workshop. The activity is suited for younger students as well, where clear…

An analysis is presented in this study that provides insight into a practical training process and its impact on teachers and their viewpoints toward the integrated STEM approach used in that training process, together with educational coding and robotics, over the first years of compulsory primary education, where STEM implementations are…

One of the aims of primary education, as suggested by the Cambridge Primary Review, should be, 'Exploring, knowing, understanding and making sense'. It should give the children 'the opportunity to encounter, explore and engage with the wealth of human experience and the different ways through which humans make sense of the world and act upon it'.…

The effects of kinetic vs thermodynamic control on "endo"/"exo" stereoisomer ratios can be observed in a simple Diels-Alder reaction between "N"-phenylmaleimide and furan. The use of microwave-promoted synthesis affords the cycloadducts in yields ranging from 65-100%, employing reaction times of 1-10 min at…

Didactic transposition theory examines the development from scientific/academic knowledge being produced by scientists to it becoming learned knowledge constructed by learners. According to the theory, four kinds of knowledge exist: scientific knowledge, knowledge to be taught, taught knowledge and learned knowledge. In this study, learning and…

This case study of an online science laboratory network, the North American Network of Science Labs Online (NANSLO), demonstrates that successful initiatives must fit well within institutions' existing structural and programmatic elements as well as align with institutional goals, course-level programming, and have adequate buy-in at the faculty…

Situated in the context of teacher education reform which vehemently emphasises inquiry-based science education, this study examined the conceptualisations and enactment of inquiry-based science education by a group of four pre-service teachers enrolled in a teacher professional development programme in India, using mixed-method research design.…

Studies have shown that inadequate definitions of scientific concepts could complicate the learning of science and could prevent students from understanding the definitions of scientific concepts. The article provides a framework for defining scientific concepts in primary, secondary, and university education by proposing teachers draw attention…

This book provides a fascinating insight into the on-going process of self-reflection in the Science|Environment|Health (S|E|H) community. The basic vision of a new S|E|H pedagogy is to establish a transdisciplinary dialogue between the three educational fields of science education, environmental education, and health education. This approach…
