The goals of the study were as follows: i) to design an active science learning activity on stoichiometry for grade 10 students, ii) to evaluate the academic achievement of grade 10 students after receiving an active science learning activity on stoichiometry, and iii) to investigate the perspectives of grade 10 students regarding an active…

Students from marginalized populations may be less likely to engage in science education and form science identities. Thus, science education should include culturally responsive pedagogy to engage students from diverse cultural and ethnic backgrounds and promote science identity in every student (Mhakure and Otulaja 2017). The author is a high…

In this study, it was aimed to examine the effects of inquiry-based activities supported by web 2.0 tools on the attitudes of students towards the chemistry lesson in the unit of 'Acids, Bases and Salts' in the 10th grade chemistry lesson. Considering the relevant achievements in the 2018 chemistry curriculum and using the web 2.0 tools Padlet and…

This article explores the possibilities of a cheap one-dollar microscope, the Foldscope, for enhancing out-of-school science education. Developed by Manu Prakash and Jim Cybulski from Stanford University, these origami-type paper microscopes make it possible to provide all students with their own microscopes, due to the low cost. This provides…

In science education, there is a now established focus on fostering students' meaning making through/as multimodal representations as part of their induction into the epistemic practices of the discipline. Increasingly, this agenda is aligned with an emphasis on nurturing students' creative reasoning, as researchers move to enrich theories of…

We present an example of a novel, model-based approach to instruction in which learners constructed a representation of a specific phenomenon, evaluated their representation, and then revised it, via an abstraction process, to construct a model. The example took place in high school in the context of solution chemistry. The aim of the instruction…

This paper highlights learning supports associated with genetics lessons that were implemented in a urban high school biology classroom. The supports provided access to science content for ELLs [English language learners], students with IEPs [individualized education programs], and struggling readers during an introductory unit on genetics. Due to…

This article describes how one teacher introduced Earth science topics to a 10th-grade biology class using a 3D printer. The activities described give students opportunities to visit Earth's geologic landmarks through kinesthetic modeling. 3D-printed topographical maps function as a supplement to, or replacement of, two-dimensional drawings,…

Background: This article describes the design and the evaluation of a student lab program on the topic of nanoscience and technology (NST), mainly focusing on Nanoscience and its applications. The program was designed for students in grades 8-10 and was part of a larger outreach program of the Collaborative Research Center 'Function by Switching'…

This study aimed at investigating the effectiveness of using Radioactivity Remote Laboratory Activities (RRLAs) in enhancing Form Four (equivalent to Grade 10) students' understanding of radioactivity and motivation to learn science. For this purpose, in this study, a repeated measures one-way ANOVA design was utilized in which 54 Form Four…

The study presents an integrated STEM activity involving a 3D printer and entrepreneurial problem solving. The study was conducted with 20 high school students who worked in groups to make their own unique kolonya (a traditional Turkish sanitizer), similar to eau de Cologne. They then designed kolonya bottles using TinkerCad before producing them…

This article describes the use of project-based instruction in activities and labs intended to develop higher-order thinking skills with high school students and pre-service teachers through the use of soap making.

Thermal cameras offer real-time visual access to otherwise invisible thermal phenomena, which are conceptually demanding for learners during traditional teaching. We present three studies of students' conduction of laboratory activities that employ thermal cameras to teach challenging thermal concepts in grades 4, 7 and 10-12. Visualization of…

For students in biology, chemistry, or environmental science, diatoms offer excellent insight into watershed health and human impact on the environment. Diatoms are found globally in virtually every habitat that has sunlight and moisture, including polar seas, tropical streams, and on moist soils and mosses. Studying diatoms as biological…

Deoxyribonucleic acid (DNA) is life's most amazing molecule. It carries the genetic instructions that almost every organism needs to develop and reproduce. In the human genome alone, there are some three billion DNA base pairs. The most difficult part of teaching DNA structure, however, may be getting students to visualize something as small as a…
