This study aims to examine the impact on environmental attitudes and awareness of kindergarten pupils of an intensive education programme based on basic science process skills including the 'reduce, reuse and recycle (3Rs)' paradigm for preschool children. A quasi-experimental pattern with non-equivalent pretest-posttest and with a control group…

Cookbook-style laboratories (labs), where students follow recipes and confirm known results are common, yet years of science teaching and learning research indicate they do not help college students develop the habits of mind and skills of a scientist. We describe the rationale, challenges, and initial changes made in our teaching and learning lab…

Past research repeatedly revealed students' struggles to understand chemical equilibria, especially concerning their dynamic nature. Black-box simulations have proven to be helpful here. However, the effect is strongly dependent on the quality of teaching, the design principles of which are not yet fully known. One aspect of debate concerns the…

Concepts and practices surrounding measurement uncertainty are vital knowledge for physicists and are often emphasized in undergraduate physics laboratory courses. We have previously developed a research-based assessment instrument--the Survey of Physics Reasoning on Uncertainty Concepts in Experiments (SPRUCE)--to examine student proficiency with…

During COVID-19 remote instruction, instructors were tasked with providing students with authentic laboratory experiences in an out-of-classroom environment. One solution developed for our introductory general chemistry laboratory involved students critiquing readily available technique videos to distinguish between correct and incorrect…

This work reports the development and application of an analytical tool for the analysis of the formation of the scientific mind of students who took part in inquiry activities, based on the philosophy of Gaston Bachelard, in a Chemistry Club. For the construction of the analytical instrument, an extracurricular course was offered to first-year…

Purpose: The purpose of this paper is to present the results of measuring a sample of engineering students' perceived achievement of complex thinking at different stages of their professional training. This study intended to analyze and predict the differences in the self-perception of achieved complex thinking competency by gender, semester,…

Scientific writing skills were an essential competency for biology students in preparing effective research reports because they enabled students to communicate their research findings clearly and professionally. These skills were crucial for ensuring that students could present their work in a manner that adhered to scientific standards,…

Molecular Cell Biology (MCB) should be taught according to the scientific practices, avoiding cumulative and memory knowledge construction, but favoring scientific thinking. A way to achieve this goal is to apply activities involving scientific news, which construct knowledge through significant learning and the development of critical thinking.…

Despite the intrinsic interdisciplinary nature of STEM, teaching interdisciplinarity in the classroom is difficult and students struggle to find the applicability of concepts and skills in different scientific disciplines. In this work we propose a micro-credential "badge" system called Demonstrated Understanding of Core Knowledge (DUCK)…

Pressure gradients serve as the key driving force for the bulk flow of fluids in biology (e.g., blood, air, phloem sap). However, students often struggle to understand the mechanism that causes these fluids to flow. To investigate student reasoning about bulk flow, we collected students' written responses to assessment items and interviewed…

Recent research suggests that integrating model-based learning and socioscientific issue based instruction helps students construct meaningful learning in science classrooms. Thus, this paper presents a unit plan that integrates model-based learning and socioscientific issues. The focus of the unit is the white butterfly which is a local pest. A…

This study investigated the effects of science, technology, engineering, and mathematics (STEM) applications carried out with the purpose of supporting the integrated knowledge of prospective science teachers on the scientific process skills and STEM education orientation skills of prospective teachers. According to the results, the STEM…

In order to acquire science, it is necessary to perform hands-on activities, make experiments and scientific inquiry with the obtained data, to be able to evaluate critically and understand the scientific concepts, as well as to collaborate and communicate. STEM learning promotes inquiring minds, logical reasoning, and communication and…

In this work, we introduce high school students to renewable energy through the exploration of the pyrolysis process, focusing on the conversion of lignocellulosic biomass into bio-oil. Students undertake a sequence of straightforward experiments in four sessions, using a handmade reactor and various types of biomasses. Outcomes such as yield…
