Amelia M. Anderson-Wile; Kelly E. Hall; Tevye C. Celius – Journal of Chemical Education, 2024
A structured series of activities has been designed and implemented to promote analysis and data reporting skills for second-year organic chemistry students. Student report sheets were developed to assist students in reporting necessary data for their compounds. A series of rubrics have been utilized by students to promote metacognition and by…

Diego Airado-Rodri´guez; David Mun~oz de la Pen~a; Isabel Dura´n-Mera´s; Jaime Domi´nguez Manzano; Arsenio Mun~oz de la Pen~a – Journal of Chemical Education, 2022
In this paper, the development of an automatic assessor is presented, both in MATLAB and in Excel, for an analytical exercise. In particular, the emulation of an interlaboratory exercise, using the analytical determination of phosphorus in a dry detergent, carried out in the laboratory by different groups of students, was selected as a case of…

Qiu-ting Huang; Yi-dan Zuo; Zhu Zhu; Liu Yang; Zhong-qun Tian; Guo-kun Liu – Journal of Chemical Education, 2024
Nitrate is a crucial parameter for assessing water quality, owing to its dual function in ecological systems. These functions can be beneficial or detrimental depending on whether nitrate concentrations are low or high, respectively. The ultraviolet spectrophotometric method (standard as 4500-NO[subscript 3]--B) is a classic method for determining…

Jausovec, Norbert; Jausovec, Ksenija – Brain and Cognition, 2012
The main objectives of the study were: to investigate whether training on working memory (WM) could improve fluid intelligence, and to investigate the effects WM training had on neuroelectric (electroencephalography--EEG) and hemodynamic (near-infrared spectroscopy--NIRS) patterns of brain activity. In a parallel group experimental design,…

Uffelman, Erich S.; Doherty, Jonathan R.; Schulze, Carl; Burke, Amy L.; Bonnema, Kristen R.; Watson, Tanya T.; Lee, Daniel W., III – Journal of Chemical Education, 2004
Microscale fusions, description, and spectroscopic analysis of the reactivity of a square planar Cu(III) complex significant to green chemistry, are presented. The experiment also includes nine focal points on which pre-lab and post-lab questions are based, and the final exams reflect the students' comprehension of these and other features of…

Blitz, Jonathan P.; Sheeran, Daniel J.; Becker, Thomas L. – Journal of Chemical Education, 2006
Qualitative analysis schemes are used in undergraduate laboratory settings as a way to introduce equilibrium concepts and logical thinking. The main component of all qualitative analysis schemes is a flame test, as the color of light emitted from certain elements is distinctive and a flame photometer or spectrophotometer in each laboratory is…
