Tracy N. Vassiliev; Douglas J. Gardner; David J. Neivandt – Science Activities: Projects and Curriculum Ideas in STEM Classrooms, 2024
This STEM research project asks middle school or high school students to work towards creating ecologically friendly packaging. Packaging that can be composted instead of thrown away and collected in landfills and oceans like plastics. This inquiry uses nanocellulose and focuses on water permeability. The fibers of nanocellulose can be dried to…

Wright, Leslie Kate; Cortez, Paulina; Franzen, Margaret A.; Newman, Dina L. – Biochemistry and Molecular Biology Education, 2022
Many biology students struggle to learn about the process of meiosis and have particular difficulty understanding the molecular basis of crossing over and the importance of homologous pairing for proper segregation. To help students overcome these challenges, we designed an activity that uses a newly developed Chromosome Connections Kit® from 3-D…

Okur, Murat; Güngör Seyhan, Hatice – International Journal of Progressive Education, 2021
In the study, the effect of Predict-Observe-Explain (POE) activities carried out within the scope of argumentation-supported learning method on the detection of the conceptual understandings of the pre-service science teachers about "Solutions: Dissolving-Melting" was examined. Based on this main purpose, a case study was applied in the…

Hasanah, Uswatun – Science Education International, 2020
In the present study, an experimental teaching material using a soundcard oscilloscope developed for science, technology, engineering, and mathematics (STEM) education considering the engineering viewpoint was applied to address student's misconceptions in the alternating current (AC) circuit topic in high school physics. Four experiments were…

Almeida, Karen H. – Journal of Chemical Education, 2022
US colleges and universities have known for decades that higher percentages of racial and ethnic subgroups leave STEM majors, contributing to racial inequality in STEM professions. Many interventions have been developed, yet the disparity persists. A partial flipped pedagogical model is presented for a General Chemistry 1 (GChem1) course that is…

Bonafe, Carlos Francisco Sampaio; Bispo, Jose Ailton Conceição; de Jesus, Marcelo Bispo – Biochemistry and Molecular Biology Education, 2018
Metabolism involves numerous reactions and organic compounds that the student must master to understand adequately the processes involved. Part of biochemical learning should include some knowledge of the structure of biomolecules, although the acquisition of such knowledge can be time-consuming and may require significant effort from the student.…

Sattizahn, Jason R.; Lyons, Daniel J.; Kontra, Carly; Fischer, Susan M.; Beilock, Sian L. – Mind, Brain, and Education, 2015
Student difficulties in science learning are frequently attributed to misconceptions about scientific concepts. We argue that domain-general perceptual processes may also influence students' ability to learn and demonstrate mastery of difficult science concepts. Using the concept of center of gravity (CoG), we show how student difficulty in…

Colaianne, Blake – Science Teacher, 2015
Misconceptions about climate change are common, which suggests a need to effectively address the subject in the classroom. This article describes a project-based science activity in which students report on the physical basis, adaptations, and mitigation of this global problem, adapting the framework of the United Nations' Intergovernmental Panel…

Muniz, Marc N.; Oliver-Hoyo, Maria T. – Journal of Chemical Education, 2014
We report a novel educational activity designed to teach quantum mechanical tunneling to upper-division undergraduate students in the context of nanochemistry. The activity is based on a theoretical framework for analogy and is split into three parts that are linked pedagogically through the framework: classical ball-and-ramp system, tunneling…

Esselman, Brian J.; Hill, Nicholas J. – Journal of Chemical Education, 2015
The electronic and molecular structure of the acylium cation ([CH[subscript 3]CO][superscript +], 1) receives varied treatment in undergraduate textbooks and online resources. The overall structure of 1 is typically represented as an equal combination of resonance structures containing C-O triple and double bonds, the latter structure occasionally…

Saunders, Cheston Andrew – Science Activities: Classroom Projects and Curriculum Ideas, 2016
Many students leave the environmental science classroom with misconceptions centered on the availability of natural resources such as water. This article presents a case study where students assume the roles of various stakeholders and articulate their position on whether or not to pipe water from the Red Sea to the Dead Sea. Additionally,…

Ghirardi, Marco; Marchetti, Fabio; Pettinari, Claudio; Regis, Alberto; Roletto, Ezio – Journal of Chemical Education, 2015
A didactic sequence is proposed for the teaching of chemical equilibrium law. In this approach, we have avoided the kinetic derivation and the thermodynamic justification of the equilibrium constant. The equilibrium constant expression is established empirically by a trial-and-error approach. Additionally, students learn to use the criterion of…

Gates, Joshua – Physics Teacher, 2014
Newton's second law is one of the cornerstones of the introductory physics curriculum, but it can still trouble a large number of students well after its introduction, hobbling their ability to apply the concept to problem solving and to related concepts, such as momentum, circular motion, and orbits. While there are several possibilities for…

Chapman, Steven – Primary Science, 2014
Electricity can be a fun topic in a primary school class. It includes many practical experiments and links to real life contexts. However, teachers can feel daunted by the subject as they think they do not know enough about the science behind it to answer off-topic questions. The reason for the difficulty is that much of the science takes place…

Davies, Tony – Primary Science, 2014
Teaching children about circuits and the way electricity works is a "tricky business" because it is invisible. Just imagine all eyes are on the teacher as he or she produces for the class what looks like a ping-pong ball and then, with a wave of their hand, the incredible happens! This wonderful white sphere begins to glow red and a…
