The various aspects of projectile motion have been analyzed many times in this journal. As a sample, over the years, authors have investigated particular details of the path of a projectile and different situations for launching projectiles. Others have written about a nifty way to determine the maximum height of a projectile, finding the range of…

Despite its proven added value, modeling-based learning (MbL) in science is not commonly incorporated into the early grades. Our purpose in this descriptive case study was to enrich our understanding of how kindergarten children enact MbL by examining these children's constructed models and their accompanying oral descriptions of their models. For…

This research paper aims to propose a novel didactic sequence inspired by an historical/epistemological study of the evolution of spectroscopy and in particular of colorimetry. The working principles of the historical color comparators and the visual color matching method, first proposed by Duboscq, stimulated us in the development of a five-step…

Here, we propose a laboratory exercise to quickly determine single nucleotide polymorphisms (SNPs) in human "alcohol dehydrogenase 1B (ADH1B)" and "aldehyde dehydrogenase 2 (ALDH2)" genes involved in alcohol metabolism. In this exercise, two different genotyping methods based on polymerase chain reaction (PCR), namely…

A novel teaching approach is aimed at elucidating the concept of bond enthalpy for general chemistry students. Through the integration of a hands-on candy pulling activity, students in a large lecture class were provided a tangible experience to explore bond strengths using rope candy and a luggage scale. Feedback from students indicated a clear…

Changing where, when, and how objects are studied is central to lab-based science (Knorr Cetina, 1999). Science involves changing the scale of objects--particularly scales of size, time, and intensity--from what is experienced in the world. Similar to investigations conducted in science laboratories, classroom investigations involve…

Three computer-based activities focusing on fundamentals of binding interactions are described that are powered by Desmos, freely available web-based software. The software allows the instructor to monitor the progress of each student completing the activity by privately viewing their answers in real time, to enforce class pacing by modulating…

The main purpose of this study is to reveal the opinions of science teacher candidates regarding the implementation of Discovery Learning-Based STEM Education in distance education with Applied Activities. The study was designed as a case study. Participants were first given basic chemistry education and introduced to the concepts of STEM,…

This study investigated meaning-making of arrows in a representation of the greenhouse effect among 14-year-old secondary school students. Data was generated during Biology lessons where 74 students discussed how they interpreted a representation from the Swedish Society for Nature Conservation, which is an NGO that produce school material. The…

The objective of the current study was to identify an effective learning environment for kindergarten students as they acquire an initial understanding of scientific inquiry activities (SIA) and a simple (idealized) scientific inquiry cycle (SIC). The study aimed to examine (a) the effects of instructional support and (b) the role of similarity…

Background: Although science and technology are viewed as closely related subjects, they are rarely combined in preschools. Purpose: This article investigates preschool teachers' perspectives on integrating digital tools when teaching science, asking how and why they use digital tools, and examining the affordances they experience and obstacles…

The aim of this research was to provide preschool children with context-based science and nature activities and basic process skills. The research was carried out with 11 children aged 48-60 months in the second term of the 2019-2020 academic years. The research was designed according to action research, one of the qualitative research designs. In…

Using Mary Shelley's "Frankenstein" as inspiration, this paper presents a Frankenstein-themed transmedia storytelling experience, which encompasses simple hands-on activities and an online narrative experience that allows students to model scientific work and engage in various science activities. The study aimed to test whether students…

The purpose of the current study is to investigate the effectiveness of unstructured, semi-structured, structured hands-on modeling activities and traditional teaching methods in developing academic achievement, problem-solving skills, and scientific creativity in prospective science teachers in the subject of the human circulatory and respiratory…

Tasks used in the Biology Olympiad (BiO) appear to be promising alternatives to traditional teaching tasks in biology education, as they frequently incorporate inquiry-based elements. This makes them a valuable resource for increasing students' exposure to inquiry activities during classroom instruction. However, for teachers to effectively…
