We introduced a microfluidic paper-based analytical device ([mu]PAD) to undergraduates majoring in nutrition education using a modified acid-base titration on paper microzones. After designing experiments for sample analysis using micro acid-base titration, students fabricated the devices and implement the experiment as designed. Then they…

With the benefits of low cost, energy efficiency, and environmental protection, photocatalytic hydrogen production is considered to be the most promising technology for the development of a clean and sustainable society. However, the utilization of photocatalytically generated hydrogen is not very common yet. Therefore, tertiary education urgently…

The Fowler Diet Cola Test (DCT) was originally developed to assess the scientific process skills of students in science classrooms. The use of the test is generally suggested for gifted students in science. There are considerable number of Scientific Process Skills (SPS) tests that the researchers developed for different student population. The…

Inorganic Chemistry teaches students the concept that modifications to ligand structures, especially the donor properties, can have a drastic impact on the reactivity and stability of the metal complexes. Experiments described here reinforce this concept through the investigation of two tetradentate ligands derived from…

The advantages of active learning approaches have prompted national recommendations for the development of inquiry-based laboratories to replace traditional laboratory classes. However, there is little consensus for the most-effective implementation strategies. Frequently, a single inquiry-based exercise is incorporated at the end of a traditional…

Experimental courses for undergraduate students majoring in biochemistry or related subjects often do not provide students with systematic and research-based experiences. To help students develop abilities related to laboratory techniques, data analysis, and systematic thought in biology, we performed an exploratory program that employs…

The ability to perform air-free chemistry and catalytic reactions on an NMR tube scale are valuable skills in chemistry and not often included in undergraduate chemistry curriculum. This laboratory experiment provides students experience in synthesizing the metal complex, Ni(dcpe)(CH[subscript 3]CN)[subscript 2](BF[subscript 4])[subscript 2] (dcpe…

"N"-Formamides are important intermediates in the synthesis of many pharmacologically active compounds and are used as protecting groups for amines or as catalysts in different reactions. The current "N"-formylation experiment is designed as a part of an introductory organic chemistry course for undergraduate students. The…

The purpose of this study was to investigate the effect of inquiry-based experiments on pre-service science teachers' science process skills. The study group consisted of 60 pre-service teachers in total, enrolled in the undergraduate program of Science Teacher Education, Faculty of Education at a state university. The study which used randomized…

This study examined the impact of a project-based learning module on young children's scientific practices in urban and Indigenous areas. The module was developed by drawing upon early science standards and research on scientific practices and project-based teaching approaches. Ninety-eight children from northern Taiwan participated. Their average…

Thermodynamic characterization of micelle formation from an ionic surfactant in aqueous solutions is a classic experiment in physical chemistry. The critical micelle concentration (CMC) and the degree of micelle ionization ([alpha)] can be directly obtained by conductimetry, then thermodynamic parameters ([delta]G[subscript m][superscript o],…

This paper reports on a study aiming at examining the development of science process skills through the implementation of experiments in a science course which was performed in flipped classroom design. Flipped classroom model was implemented for a series of experimentation activities in a science classroom in which 38 science teacher candidates…

For the past several decades, high-enrollment undergraduate chemistry laboratory experiences have favored traditional approaches involving disparate daily experiments with optimized protocols provided to students. This model often results in poor learning outcomes and low student engagement, and it lacks any attention to scientific inquiry. Here,…

In this study, the primary goal was to enhance the knowledge and awareness of 4th-grade primary school students regarding global pandemic diseases and methods of safeguarding against worldwide epidemic diseases which are socio-scientific issues. To achieve this goal, two activity modules tailored for 4th-grade students were created. These…

As a cross-cutting and comprehensive subject, medicinal chemistry involves the knowledge of chemical, biological, medical, and pharmaceutical sciences. A comprehensive medicinal chemistry experience for undergraduates is expected to train various experimental skills and enhance their scientific research ability. Herein, a series of laboratory and…
