Renderos, Genesis; Aquino, Tawanda; Gutierrez, Kristian; Badiei, Yosra M. – Journal of Chemical Education, 2017
Artificial photosynthesis (AP) is a synthetic chemical process that replicates natural photosynthesis to mass produce hydrogen as a clean fuel from sunlight-driven water splitting (2H[subscript 2]O [right arrow] O[subscript 2] + H[subscript 2]). In both natural and artificial photosynthesis, an oxygen-evolving catalyst (OEC) is needed to catalyze…

Love, Tyler S.; Roy, Ken R. – Technology and Engineering Teacher, 2017
The beginning of a new school year can be hectic, but it is an opportune and critical time for teachers, supervisors, administrators, and school systems to establish proper safety procedures and practices. It can be more difficult to correct inappropriate behaviors or unsafe habits later in the year. This is especially true if a safety accident…

Bell, Peter T.; Whaley, W. Lance; Tochterman, Alyssa D.; Mueller, Karl S.; Schultz, Linda D. – Journal of Chemical Education, 2017
NMR spectroscopy is currently a premier technique for structural elucidation of organic molecules. Quantitative NMR (qNMR) methodology has developed more slowly but is now widely accepted, especially in the areas of natural product and medicinal chemistry. However, many undergraduate students are not routinely exposed to this important concept.…

Yamashita, Shuichi; Kashiwaguma, Yasuyuki; Hayashi, Hideko; Pietzner, Verena – Science Education International, 2017
In science classes, students usually learn about the law of definite proportions by the oxidation of copper. However, common procedures usually do not lead to proper results. This leads to confusion among the students because their experimental results do not fit to the theoretical values. Therefore, we invented a new procedure for this experiment…

Schmidt-McCormack, Jennifer A.; Muniz, Marc N.; Keuter, Ellie C.; Shaw, Scott K.; Cole, Renée S. – Chemistry Education Research and Practice, 2017
Well-designed laboratories can help students master content and science practices by successfully completing the laboratory experiments. Upper-division chemistry laboratory courses often present special challenges for instruction due to the instrument intensive nature of the experiments. To address these challenges, particularly those associated…

Kodejška, C.; Ganci, S.; Ríha, J.; Sedlácková, H. – Physics Education, 2017
This work is focused on the experimental verification of the balance between the atmospheric pressure acting on the sheet of paper, which encloses the cylinder completely or partially filled with water from below, where the hydrostatic pressure of the water column acts against the atmospheric pressure. First of all this paper solves a theoretical…

Carvalho, Josue´; Queiroz, João A.; Cruz, Carla – Journal of Chemical Education, 2017
Circular dichroism (CD) has emerged as one of the standard biophysical techniques for the study of guaninequadruplex (G4) folding, cation effect, and ligand binding. The utility of this technique is based on its robustness, ease of use, and requirement of only small quantities of nucleic acid. This experiment is also extendable to the classroom…

Muthyala, Rajeev S.; Butani, Deepali; Nelson, Michelle; Tran, Kiet – Journal of Chemical Education, 2017
Sense of smell is one of the important senses that enables us to interact with our environment. The molecular basis of olfactory signal transduction is a fascinating area for organic chemistry educators to explore in terms of developing undergraduate laboratory activities at the interface of chemistry and biology. In this paper, a guided-inquiry…

Bastos, Rodrigo Oliveira; Boch, Layara Baltokoski – Physics Education, 2017
Although quantitative measurements in radioactivity teaching and research are only believed to be possible with high technology, early work in this area was fully accomplished with very simple apparatus such as zinc sulphide screens and electroscopes. This article presents an experimental practice using the electroscope, which is a very simple…

Neves, Ben-Hur S.; Altermann, Caroline; Gonçalves, Rithiele; Lara, Marcus Vinícius; Mello-Carpes, Pâmela B. – Advances in Physiology Education, 2017
Different tools have been used to facilitate the teaching and learning process in different areas of knowledge. Practical activities represent a form of teaching in which students not only listen to theoretical concepts but are also able to link theory and practice, and their importance in the biological sciences is notable. Sometimes, however,…

Albright, Jessica C.; Beussman, Douglas J. – Journal of Chemical Education, 2017
Capillary electrophoresis is an important analytical separation method used to study a wide variety of samples, including those of biological origin. Capillary electrophoresis may be covered in the classroom, especially in advanced analytical courses, and while many students are exposed to gel electrophoresis in biology or biochemistry…

Schellhammer, Karl Sebastian; Cuniberti, Gianaurelio – Journal of Chemical Education, 2017
We are hereby presenting a didactic concept for an advanced lab course that focuses on the design of donor materials for organic solar cells. Its research-related and competence-based approach qualifies the students to independently and creatively apply computational methods and to profoundly and critically discuss the results obtained. The high…

Nobles, Mia; Fraizer, Lani – HAPS Educator, 2017
Although literature posits the invaluable role of educators as both teachers and leaders in cultivating meaningful student learning experiences, many educators do not identify themselves as leaders (Barth, 2001). This paper explores leadership strategies for cultivating teacher-leader identity in Anatomy and Physiology educators. Due to large…

Luvanga, Baraka Gaitan; Mkimbili, Selina Thomas – African Journal of Research in Mathematics, Science and Technology Education, 2020
This paper presents the findings of a study that explored the link between teachers' views on the challenges to inquiry-based science teaching (IBST) practice in the chemistry classroom and their need for professional development. The study used a multiple case study design and collected data using interviews. Participants were purposively…

Lee, Star W.; Ing, Marsha – CBE - Life Sciences Education, 2020
Research suggests there are potential benefits to students when taught by instructors who share the same gender and/or race/ethnicity. While underrepresented students have shown increased persistence and academic performance when they were taught by gender- and/or race/ethnicity-congruent faculty, there is little research that has explored the…
