In analytical chemistry, discussing different method sand techniques of analysis is essential to promote critical thinking and reasoning. Analytical courses in the chemist, pharmacist, and biochemist curricula represent the opportunity to study concepts such as experimental design, sampling, development, and optimization of protocols, data…

An experiment for the upper-level biochemistry laboratory is described in which students isolate a wild yeast from environmental sources and characterize the strain for its potential in the brewing industry. In addition to providing valuable experience in important biochemical techniques, this study also illustrates key principles of…

This article describes two sets of experiments designed to enhance the understanding of colloidal systems. These experiments were designed as a part of the theme "Colloids: Where Science Meets Engineering" taught in the Department of Chemical Engineering and additionally offered to physics, chemistry, and materials science departments as…

A science camp for blind or visually impaired (BVI) students, covering mainly hands-on chemistry experiments, is described. The scientific experiments are detailed, and the feedback of the students is recorded, highlighting the benefits of the camp and its impact. BVI students actively participated in conducting the scientific experiments using…

The COVID-19 pandemic, which emerged in early 2020, forced educational institutions in Thailand to chiefly rely on online learning during the government mandated lockdown for almost two academic years. Although migration to the online format seems to suit lectures, it is inadequate for laboratory courses since students could not do the experiment…

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?…

In this quantitative study, we explored learners' intrinsic motivation towards three different experimental physics educational activities offered by our department to upper-grade high school students. The inspected activities were lecture demonstrations, a science show, and hands-on practical work. The respondents were Czech high school students…

Floating and sinking (FS) is a key topic in science education, both at primary and secondary levels. The interpretation of FS phenomena, however, is challenging due to the difficulty of the scientific concepts and explanatory models involved (e.g., density, buoyancy), along with students' everyday experiences, which conflict with scientific…

Hydrogen is a sustainable and climate-friendly storage for renewable energies and can directly be generated from sunlight, e.g., by photocatalytic water splitting. This article presents the photocatalytic hydrogen evolution using LED irradiation of an aqueous ZnS particle dispersion with Na[subscript 2]S and Na[subscript 2]SO[subscript 3] as…

Interactive computer simulations and hands-on experiments are important teaching methods in modern science education. Especially for the communication of complex current topics with social relevance (socioscientific issues), suitable methods in science education are of great importance. However, previous studies could not sufficiently clarify the…

A pilot study, funded by the Gatsby Charitable Foundation, supported 10 secondary schools across England to plan and deliver open-ended investigative practical work within science curriculum time. This enabled all students to experience the benefits of investigative work, rather than just those attending extracurricular STEM enrichment activities.…

The ability of students to perform quantitative analysis is a fundamental aspect of analytical chemistry courses and laboratories. In this laboratory experiment, students quantitatively analyze both liquid and solid samples through the use of internal standard calibration and ATR-FTIR spectroscopy. Using a problem-based approach to selecting their…

This paper discusses the emergence of science education in the seventeenth century with the influences of Joseph Priestley on the Dissenting Academies. Primarily, this paper analyses Priestley's ideas from some of his letters to scientists during his time and his ideas from his books "Miscellaneous Observations Relating to Education"…

Contribution: A do-it-yourself (DIY) light wave sensing (LWS) and communication project was developed to generate interest and clarify basic electromagnetic (EM) and wireless sensing/communication concepts among students at different education levels from middle school to undergraduate. This article demonstrates the nature of the project and its…

Affective and cognitive outcomes of science teaching in schools may be enhanced by science outreach labs (SOLs). Particularly interesting is whether and how to connect SOL visits to in-school science learning. Recent studies--among others, in this journal--have confirmed SOLs' positive affective effects. However, research remains inconclusive…
