The growing interest in outdoor early childhood education, even in countries with a weak environmental tradition such as Portugal, tends to be associated with a concern over the alienation between urban/Western children and nature. While educational projects in nature criticize this separation, they still maintain a bad culture vs good nature…

Raman scattering spectroscopies are important analytical tools in modern chemistry. Here, we describe the construction of the unamplified Raman scattering analysis (URSA) instrument: an inexpensive, open-table Raman spectrometer that uses a 532 nm diode-pumped laser as a light source. Upon application of this spectrometer to DNA extracted from…

This study analyze data from three national contexts in which teachers worked with the same teaching materials and inquiry classroom activities, investigating teachers' use of strategies to promote interaction and scaffolding when participating in a professional development program. The data material is collected from three case studies from the…

The COVID-19 pandemic presented significant challenges for both students and educators, particularly because of the virtualization of classes and the consequent lack of practical sessions following the closure of laboratories and experimental fields in universities. The absence of interaction among students and practical classes led to a…

Biodiversity is a multidimensional concept, and its integration into school curricula is essential for promoting sustainable development. Plants are central to the biodiversity of ecosystems; however, student teachers often fail to recognize them and understand their importance. This phenomenon, known as "plant blindness," was first…

This descriptive qualitative case study aims to find out the pre-service science teachers (PST)' confidence about instructional practice in outdoor setting, their knowledge about the plants and it explores the two research questions: To what extent do the preservice science teachers have confidence to teach in the outdoor settings? (1) and What…

Preschoolers have different experiences in different environments. These experiences can stimulate children's imaginations. This longitudinal study examines the impact of preschool children's three-year experiences in early childhood institutions, which are their primary educational environments. The question 'Do preschoolers imagine different…

Plant morphology courses develop students' understanding of plant structures and identification skills through mini-research activities. Effective species identification requires a literature review and the ability to find, evaluate, and use relevant information. This qualitative study examines students' information literacy skills in completing…

We investigated the effect of short-term teaching (3 weeks) using image analysis on gymnasium/secondary school students' (ISCED3A) skills (science process skills, SPS) and knowledge using Fiji (ImageJ) software. The theoretical teaching was combined with IT-based education (measurement of the area or signal intensity on photos from scientific…

In this paper, we explore the ways that a STEAM-focused summer program for Indigenous youth supported learning in accordance with Indigenous axiologies (what we value esthetically or morally), ontologies (what we believe to be real and how we enact those beliefs), and epistemologies (what we know and how we know it) or AOE. Part of these AOEs…

Previous research indicates that young children, as young as preschoolers, spontaneously draw dihedral and cyclic symmetries in their representations of the natural world. This is an intriguing find because at this age children have barely had their first contact with formal geometry and, therefore, one would not expect to find a use of symmetries…

The wonderful plants and animals of the Daintree Rainforest in Queensland, Australia, are at risk of extinction. They and the rainforests of the world must be protected by taking action on climate change.

A hydroponics experiment growing microgreens was piloted by seniors where trials were conducted over 9-day growth periods and designed to test 12 different growth conditions in triplicate, including varying nutrient supply, nutrient flow rate, and seed density. Plant growth was assessed through changes in daily mass, height, and final dry weight.…

Explanation of natural phenomena at one level of biological organisation almost always involves causes that are found at other levels. Although scientists thinking across levels find it easy to explain physiological phenomena, students often perceive this as a challenge. We developed a new graphic organiser called Zoom Map, which is a mode for…

The current study uses the Rasch Model to measure lower-secondary school students' critical thinking skills on photosynthesis topics. Critical thinking skills are considered essential in science education, but few valid and practical measurement instruments remain. The current study fills the gap by adapting the instrument from the Watson-Glaser…
