In order to evaluate students' development of scientific competence at the intermediate level, a guided-inquiry course was developed to increase student independence, including opportunities for project ownership and significant collaborative learning expectations. A survey was developed to assess students' experiences learning the scientific…

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…

The unforeseen COVID-19 pandemic forced educational institutions to shift to a remote or distance-learning mode. As a result, classes were offered online, and this shift in teaching modality presented great challenges, especially in teaching laboratory courses. While several options are available, we evaluated the use of (i) videos of lab…

Student enrollments in online college courses have grown steadily over the past decade, and college administrators expect this trend to continue or accelerate. Despite the growing popularity of online education, one major critique in the sciences is that students are not trained in the hands-on skills they may need for the workforce, graduate…

Learning Undefeated is a nationwide nonprofit organization committed to providing equitable access to STEM education for under-resourced communities. Their approach is experimental and entrepreneurial, blending lessons from both education and business to develop content that is current and exciting. This article examines how the organization…

Research experience is becoming an increasingly crucial element of today's undergraduate science curriculum. In recent years, the establishment of the Course-Based Undergraduate Research Experience Network (CUREnet) has provided a framework for the development of courses aiming to cultivate students' proficiency in undergraduate research…

During the COVID-19 pandemic, many colleges switched to online or hybrid formats for both lecture and laboratory course delivery. While virtual experiments, that is, "dry lab" experiences, teach students chemical theory, it is essential for students in chemistry laboratories to participate in hands-on laboratory activities. These…

An integrated laboratory experiment was designed for introducing biochemistry students to basic static biochemistry to deepen their understanding on the properties and analysis of biomolecules such as total carbohydrates, lipid, protein, and protein-constituent amino acids. Food represents a very important source of biomolecules of technological…

Spectrometers play a decisive role in the education of A-level and/or under-graduate students in the field of natural sciences. They are capable to demonstrate atomic emission, transmission, reflection and fluorescence spectra, but can be used for wavelength filtering, as well. Here, we present a do-it-yourself spectrometer setup based on a…

The key purpose of this research is to discuss the role of trajectory movements from education and awareness of sustainability perspective in the higher educational sector. The study analyzes how the trajectory movement of students in various academic places of their interest influences sustainable academic performance. A person-administered…

Science diagrams are an integral part of science because they are an important means of conveying and visualizing abstract science content. In recent years, researchers have demonstrated the educational benefits of encouraging students to draw their own conceptual diagrams, rather than focusing on interpreting diagrams given to them. To help…

This article illustrates how we incorporated discourse-based interviews (DBIs) into a mixed-methods research study informed by the heuristics of institutional ethnography (IE). As the first stage of a longitudinal study designed to understand what, where, and how "writing" means across our university, our research used DBIs in a writing…

This study aims to examine the effects of argumentation-supported problem-based learning (AS-PBL) carried out in the Chemistry-II laboratory course on the conceptual understanding of prospective science teachers about "Chemical equilibrium and Le-Chatelier's principle". The prospective teachers' answers were analyzed using content…

This study examined the effect of blended laboratory experiments on pre-service physics teachers' (PSPTs') attitudes toward physics laboratories. The research design was a quasi-experimental pre-test and post-test comparing groups. Participants were 63 2nd-year PSPTs' enrolled in a physics diploma program from three colleges of teacher education.…

This study shows how students can learn about green and sustainable chemistry by using the knowledge perspective of a local indigenous culture as a starting point. This learning approach encourages students to learn chemistry by connecting culture with learning about green chemistry. The cultural context selects the use of a phytochemical agent…
