“…Como reconocen los protagonistas surgió, al menos en parte, para dar solución al problema de renovación, a un coste asequible, de un laboratorio de Química Orgánica obsoleto que no cumplía con la reglamentación vigente. Las técnicas y materiales necesarios fueron desarrollados en 1982, los primeros resultados se dieron a conocer en 1984 (Pike et al, 1984;Butcher et al, 1984) y fueron publicados el año siguiente (Butcher et al, 1985;Mayo et al, 1985).…”

<span>Aparentemente la química en microescala no representa nada nuevo. Cuando los de mi generación echamos una mirada retrospectiva a nuestra época de estudiantes, allá por la década de 1960, recordamos que, por ejemplo, en los laboratorios de Química General la determinación de puntos de fusión se hacía con muestras de unos pocos miligramos en un capilar adosado a un termómetro que se introducía en el tubo de Thiele; en los laboratorios de Química Analítica el reconocimiento de aniones y cationes se realizaba frecuentemente a través de ensayos a la gota y la determinación complejométrica de metales con AEDT...</span>

“…Since Mayo et al first performed microscale organic synthesis with reagent consumption at the mmol level in the 1980s, − the past several decades have witnessed the widespread application of microscale chemistry experiments (MCEs) in chemical education at universities and high schools. − MCEs are experiments that consume minimal amounts of reagents in miniaturized instruments while still providing the required chemical information. MCEs are more cost-effective and environmentally friendly than conventional chemistry experiments, owing to reduced reagent consumption and waste production.…”

Microfluidic-based ultramicroscale chemistry experiments involve the manipulation and consumption of reagents on a microliter or submicroliter scale in a microfluidic device. This article presents the pedagogical functions of microfluidic systems, including green chemistry education, stimulation of students’ interest in learning about chemistry, interdisciplinary education, and learning of scientific knowledge. We also review the development of educational courses and platforms for implementing microfluidic education and examine the teaching and learning forms in microfluidic education, including demonstrations, laboratory experiments, comprehensive training, inquiry-based activities, and project or problem-based learning.

“…Microscale technique, also known as small scale technique, is an environmentally viable option for conducting chemical processes through laboratory experiments using small quantities of starting materials without compromising the quality and standard of chemical applications in education and the industry. In this sense, students who used to work with 10-50 g of reactants and 50-500 g of solvent may now work with only about 10-150 mg of starting materials and 1-10 g of solvent (Buther et al, 1985).…”

The introduction of the Chemistry MicroLab Kit (CμLK) aims to assist student learning of chemistry in a more interactive and practical way. Each kit was designed to address certain topics in chemistry that may otherwise be too abstract to do in a lecture-discussion set up. Among the many topics tackled in secondary school, 13 undergraduate students were hand- picked for this preliminary study. The test subjects for this initial phase of the research both majors and non-majors, were currently enrolled in a Chemistry course. It was also triedout at the Institute for Teaching and Learning (formerly Center for Teaching and Learning) with selected third year students. In this preliminary study, the students found three activities to be interesting and well-balanced: Gas Laws in a Box, Particulate Nature of Matter, and Solution Rules. In assessing the activities, they highly rated the easy language used for understanding the procedures, followed by setup of the experiments and a step-by-step presentation of the procedures. Initial results of the study find it a promising addition to the secondary level chemistry activities because CμLK enhances students' attitudes and motivation toward chemistry laboratory work.
