High-school teachers and students do not usually have access to scientific research advances because original research papers contain many highly specialized words that are specific to the discipline. Scientific newsletters (SNs) summarize current scientific research advances and trends. During the 2022-2023 school year, 21 SNs teaching biology…

In this paper, a self-created analogy is presented based on comparing the process of osmosis with a situation recreated in a train carriage. It was implemented with upper-secondary education students at a secondary school in Chiclana de la Frontera (Cádiz, Spain). To assess the progression of the students' models on osmosis, their activities…

The main research question of this research study is how to design a valid and reliable holistic rubric to be used as a criterion for the comparison of the STEAM model by analyzing different countries' science curricula. Considering this question, STEAM model rubrics was created by examining the ways of shaping science education policies. The…

Ventura, California's 2023 winter storm activity underscored the impact that runoff has on recreational water quality and public health. To examine public perception of stormwater runoff, coastal water quality, and community decision-making toward recreating in polluted water, an online survey of the Ventura River watershed community determined…

Engagement can be situative and, when it occurs, a number of experiences will co-occur. The present study examined the co-occurred experiences of optimal learning moments (OLM), a type of situated engagement, using the novel network analysis and including data from two countries: Finland and the US. Both samples were from high schools and were…

In this article, simple models of optical computing circuits (1 x 4 demultiplexer (DEMUX), 4 x 1 multiplexer (MUX), Boolean logic, and half-adder (HA)) are shown with mechanically controlled plane mirrors. Photographs of the proposed computational circuits are also shown. It is very useful for the school student to understand optical logic and…

The gender gap in physics in Australian secondary schools remains a significant issue. This study aims to address this problem by examining how physics teachers perceive girls' participation in physics, and how these perceptions influence their approach to gender issues and their potential impact on girls' physics identity. The study uses a…

This dissertation is an invitation into our beloved biology classroom. Weaving hermeneutic phenomenology and critical participatory teacher action research, this study investigated self as teacher and two cohorts of student participants in a high school biology experience utilizing an 'Aina Aloha praxis. Articulating my ongoing 'Aina Aloha praxis,…

In the present research, the "DNA Model with Clothespins" activity was designed to teach the subjects of nucleotide, DNA, and DNA replication, which are abstract subjects of science. The aim of the research, which was carried out with 20 students in 8th grade, was to examine the effects of the activity on students' achievement on the…

This case study examines students' perception, motivation, and learning gain of a teaching unit featuring wireless sensors as tools to collect scientific data in the classroom. Students analyze data using the corresponding cellphone app, communicate findings to the class, and learn about a changing environment. Wireless sensors are produced for…

Interest affects learning; it also affects students' attitude towards science and career choices. It is therefore urgent to increase students' interest and improve their attitude towards science to face the complex challenges of the future. This study transformed cutting-edge induced pluripotent stem cells (iPSC) research into an informal science…

We here propose a simple and fast hands-on activity requiring limited equipment, to introduce students of various levels (bachelor's or high school) and backgrounds (from science to arts) to the chemistry of color. The different colors of stained glass are replicated through the deposition, on ordinary glass slides, of silica coatings colored by…

In this research, we have explored the possible differences in students' performance in grade nine chemistry exams that could have been influenced by a different instructional approach in grade eight. We compared two groups of students: one group had received a transmissive propaedeutic approach in grade eight (especially related to the memorising…

A good number of instructional strategies are identified to help students overcome their learning difficulties in the mole concept. However, Ghanaian senior high school students continue to have difficulties in the mole concept. Hence, there was the need to examine the perceived nature of learning the mole concept in the perspectives of male and…

A scientific conceptual understanding of photosynthesis and respiration provides an important basis for understanding nature and the regulations of life. Photosynthesis and respiration are complex processes, and learning about them requires a proper understanding of their various aspects, from molecular biology to the ecosystem level. This study…
