There is a growing need for chemistry students to be able to handle and manipulate large datasets and analyze them in an efficient and accessible way. This creates the need to develop course materials that introduce these topics early in the undergraduate curriculum. To address this growing need, this activity introduced RStudio to students…

A procedure to purify anthocyanin, a natural pigment, following a green approach by using macroporous resin and its encapsulation for the maintenance of its stability is described. This laboratory experiment, which describes the benefits of using resin for the purification, is a learning tool for students working in the field on nutraceuticals.…

Isoenzymes are variant forms of the same enzyme activity that exhibits different tissue distribution. When cells are damaged, intracellular content leaks into the blood stream, making them potential biochemical markers. Undergraduate health sciences students are expected to interpret laboratory findings of serum levels of biochemical markers and…

The study focused on the development of a website that can be used in various fields of science in Junior High School. Particularly, topics that were utilized as part of the re-search report include chromosomes, DNA, and genes for grade 9 learners. This exploratory case study explored learners' engagement and performance on a developed virtual…

In recent years, pedagogical advancements have allowed the adoption of more engaging forms of course assignments to help students better understand and communicate chemistry. In this context, informational graphics, known as infographics, emerge as an effective teaching aid in educational settings and in disseminating scientific content to the…

The scope of this preliminary study revolves around investigating the effectiveness of experiential learning in upper-year science laboratory courses in a post-pandemic era. In this study we have explored two key questions: 1. Can experiential learning facilitate independent inquiry in an upper-year undergraduate laboratory in a post-pandemic era?…

This paper examines the findings obtained in a chemistry laboratory course provided through online hands-on activities during the pandemic. Case study design, one of the qualitative research methods, was used. The data collection period was 8 weeks. The study was carried out with 16 third-year pre-service science teachers within the scope of a…

The teaching of laboratory skills to undergraduate students is central to all experimental sciences. In this setting, students must understand the experimental procedures as well as the fundamental principle(s) being demonstrated, all while learning within a limited time. Other limiting factors include access to equipment and reagents, resulting…

Science education at different levels can be supported by various mobile applications that can be downloaded for free onto mobile phones, tablets, and other devices. Such applications can also be used in laboratory work, but it must be said that their use in science laboratories is a relatively new approach. This study is aimed at determining the…

A novel undergraduate analytical chemistry experiment involving the identification and quantification of linalool in essential oils was developed. The experiment uses the internal standard method with headspace solid phase microextraction (SPME) and gas chromatography--mass spectrometry (GC-MS). This method is applicable to any linalool-containing…

This project introduces green chemistry to the undergraduate laboratory through two pedagogical techniques: undergraduate research and guided-inquiry. Through these two learning activities, an efficient synthetic procedure for the PRINS cyclization of citronellal into isopulegol, focused on minimizing negative environmental impact, was developed.…

Polymer Chemistry is a subject in the Chemistry Programs, student have a natural curiosity about polymeric materials, that we use in our everyday activities. Our proposal is to apply cooperative learning in the Interfacial polymerization of Nylon 6,10 experimentation. The specific objectives of our project can be summarized as: To identify the…

Active learning pedagogies offer opportunities to increase student engagement and interest in plants. The Mystery Plant Project is a hands-on, semester-long active learning pedagogy I developed for an introductory, undergraduate Plant Biology course. Students investigate various aspects of their mystery plant species using observations, and…

The knowledge of the mechanical properties of polymers and other materials is essential for several tasks in the field of materials science, like component design and material development. The tensile test is one method of determining many of the material's most defining mechanical characteristics. However, the teaching of laboratory experiments…

Three direct complexometric titration methods for bismuth subsalicylate determination in over-the-counter stomach relief caplets and liquids are presented, as well as a UV-vis assay, for use in student laboratories. The main difference between titration methods is the choice of indicator; either xylenol orange (XO), pyrocatechol violet (PV), or…
