Ison, A.; Ison, E. A.; Perry, C. M. – Journal of Chemical Education, 2017
An effective way of teaching undergraduates a full complement of research skills is through a multiweek advanced laboratory experiment. Here we outline a comprehensive set of experiments adapted from current primary literature focusing on organic and inorganic synthesis, catalysis, reactivity, and reaction kinetics. The catalyst,…

Armstrong, Christopher; Burnham, Jennifer A. J.; Warminski, Edward E. – Journal of Chemical Education, 2017
A good-yielding two-step synthesis of RuH[subscript 2](CO)(PPh[subscript 3])[subscript 3] using conventional or microwave-assisted reflux techniques is described for use in undergraduate teaching laboratories. RuH[subscript 2](CO)(PPh[subscript 3])[subscript 3] is synthesized from RuCl[subscript 3]·xH[subscript 2]O, PPh[subscript 3], and KOH in…

Wheeler, Lindsay B.; Clark, Charles P.; Grisham, Charles M. – Journal of Chemical Education, 2017
Laboratory course redesign and effective implementation of an inquiry-based curriculum can be challenging, particularly when teaching assistants (TAs) are responsible for instruction. Our multiyear redesign of a traditional general chemistry laboratory course has included transitioning to a project based guided inquiry (PBGI) curriculum that…

Kaar, Taylor; Pollack, Linda B.; Lerner, Michael E.; Engels, Robert J. – Physics Teacher, 2017
The use of systems in many introductory courses is limited and often implicit. Modeling two or more objects as a system and tracking the center of mass of that system is usually not included. Thinking in terms of the center of mass facilitates problem solving while exposing the importance of using conservation laws. We present below three…

Fernández, Alberto; López-Torres, Margarita; Fernández, Jesús J.; Vázquez-García, Digna; Marcos, Ismael – Journal of Chemical Education, 2017
A laboratory experiment for students in advanced inorganic chemistry is described. In this experiment, students prepare two metal complexes with a potentially bidentate-carbene ligand. The complexes are synthesized by reaction of a bisimidazolium salt with silver(I) oxide or palladium(II) acetate. Silver and palladium complexes are binuclear and…

Estevão, Mónica S.; Martins, Ricardo J. V.; Alfonso, Carlos A. M. – Journal of Chemical Education, 2017
An experiment exploring the chemistry of the carbonyl group for the one-step synthesis of "trans"-4,5- dibenzylaminocyclopent-2-enone is described. The reaction of furfural and dibenzylamine in the environmentally friendly solvent ethanol and catalyzed by the Lewis acid ErCl[subscript 3]·6H[subscript 2]O afforded the product in high…

Schecter, Aaron Mitchell – ProQuest LLC, 2017
Multiteam systems (MTS) are an organizational form comprised of two or more independent teams which share at least one common goal. These "teams of teams" can be found in all areas of life, from business to medicine, science to the military. Accordingly, it is of great interest to determine how these systems function, and what makes a…

Finne, Laura Teinholt; Gammelgaard, Bente; Christiansen, Frederik Voetmann – Chemistry Education Research and Practice, 2023
In the undergraduate student laboratory teaching, one of the most common goals is developing improved conceptual understanding linking theory and practice. This study presents a phenomenographic analysis of pharmacy students' conceptions of the theory--practice relation in the laboratory. Through semi-structured interviews with pharmacy students…

Tseng, Yi-Kuan; Lin, Fan-Sheng; Tarng, Wernhuar; Lu, Yu-Ling; Wang, Tzu-Ling – Journal of Baltic Science Education, 2023
Physical and virtual labs have unique capabilities that can influence how students learn from them. The purpose of this study was to examine the effect of physical and virtual manipulatives on students' learning of heat and temperature and to examine the influence of various combinations of physical and virtual manipulatives. A total of 205…

Dewhirst, Courtney Beers – Early Child Development and Care, 2023
High quality field or practicum experiences are important for preparing preservice teachers for the profession. Studies suggest preservice teachers rate their practicum experiences more favourably when their cooperating teachers mentor them using apprenticeship-type practices. There is scant research on how such an approach is used in early…

May, Dominik; Morkos, Beshoy; Jackson, Andrew; Hunsu, Nathaniel J.; Ingalls, Amy; Beyette, Fred – European Journal of Engineering Education, 2023
The COVID-19 pandemic forced universities to suspend face-to-face instruction, prompting a rapid transition to online education. As many lab courses transitioned online, this provided a rare window of opportunity to learn about the challenges and affordances that the online lab experiences created for students and instructors. We present results…

Coleman, Philip; Hosein, Anesa – European Journal of Engineering Education, 2023
Laboratory tasks often focus on mechanical procedures leaving limited time and opportunities for students to build conceptual knowledge. We investigate to what extent introducing simulation tasks to preparation work can enable students to build their conceptual knowledge. We surveyed two cohorts of students taking an electronics module. Laboratory…

Shan, Jianying; Shen, Jie; Dong, Li; Xu, Yifan; Li, Honglin; Zhong, Lichao; Tang, Hao – Journal of Biological Education, 2023
Human ageing and age-associated diseases are among the greatest challenges and financial burdens faced by developed countries. Unfortunately, undergraduate students often do not experience any laboratory training in ageing research in the current laboratory curriculum of majors in biology, biotechnology, or medicine. In this study, we developed…

Öztürk, Ayse; Deniz, Islim Derya – Educational Research: Theory and Practice, 2023
In this action research study, it was aimed to develop proficiency in Science Laboratory Practices (SLP) for prospective classroom teachers (PCTs) with the online flipped learning model in the distance education process in the COVID-19 pandemic. A 14-week course was designed for the study. The results demonstrated that PCTs showed proficiency…
