The integration of theory and practice constitutes an anchor of today's technical vocational education and training (T-VET) and a major determinant of professional development. Understanding such integration is expected to contribute to pedagogical advancement and to provide new research tools. Current knowledge on the epistemological roots of…

Chemistry self-efficacy (CSE) was identified as a critical affective construct to predict student success in chemistry classrooms. We surveyed students at the beginning and toward the end of a semester to measure students' CSE beliefs in introductory and general chemistry courses at a Hispanic-serving institution in the United States. First, the…

Lab-based learning is an essential part of any undergraduate chemistry curriculum as it incorporates necessary and required hands-on experiential learning. However, in response to the COVID-19 pandemic, many students are learning from home, rendering laboratory instruction a particular challenge. Options for educators include third party virtual…

Chemistry learning in high school should encourage the application of knowledge learned to solve real-world problems around students without delay. This study aimed at analyzing the effect of the project based e-learning model (PjBeL) compared to direct e-learning (DeL) and academic procrastination (AP) on students' critical thinking skills and…

General chemistry are key gateway courses for many Science, Technology, Engineering, and Mathematics (STEM) majors. To improve student outcomes, it is critical both to identify at-risk students and implement evidence-based instructional strategies and interventions. These remain active areas of investigation, with recent literature showing that…

Integrated assessment evaluates language proficiency through tasks that require the test-taker to produce a written or spoken output based on listening or reading comprehension (reading or listening-into-writing or speaking). Since integrated assessment aims at reflecting the communicative and cognitive requirements of academic life and other…

As digital educational media use becomes more widespread, an opportunity exists to develop new methods to present abstract ideas to provide a more meaningful learning experience. Drawing from psychology and dynamic visualization research, new interactive tools can be thoughtfully designed but it is also necessary to establish how these media are…

The Lawson classroom test of scientific reasoning is a quite popular and widely used tool that measures the level and development of the student's scientific reasoning skills. In this contribution, the results of this test for the N=446 students of the Faculty of Science Palacký University Olomouc from the years 2018-2020 at the beginning of their…

Undergraduate-level laboratory experiments that involve the synthesis of nanomaterials with well-defined/controlled shapes are very attractive under the umbrella of nanotechnology education. Herein we describe a low-cost and facile experiment for the synthesis of Cu(OH)[subscript 2] and CuO nanowires comprising three main parts: (i) synthesis of…

This lab experiment describes a complete method to fabricate an enzymatic glucose electroanalytical biosensor by students. Using miniaturized and disposable screen-printed electrodes (SPEs), students learn how to use them as transducers and understand the importance SPEs have acquired in sensor development during the last years. Students can also…

The aim of this laboratory experiment is to utilize graphene oxide (GO) material to introduce undergraduate students to many well-known concepts of general chemistry. GO is a new nanomaterial that has generated worldwide interest and can be easily produced in every well-equipped undergraduate chemical laboratory. An in-depth examination of GO…

Marie Ståhl and Anita Hussénius have defined what discourses dominate national tests in chemistry for Grade 9 in Sweden by using feminist, critical didactic perspectives. This response seeks to expand the results in Ståhl and Hussénius's article "Chemistry inside an epistemological community box!--Discursive exclusions and inclusions in the…

The principles of process-oriented guided inquiry learning (POGIL) are applied to a binary solid-liquid mixtures experiment. Over the course of two learning cycles, students predict, measure, and model the phase diagram of a mixture of fatty acids. The enthalpy of fusion of each fatty acid is determined from the results. This guided inquiry…

Similar to other online courses, massive open online courses (MOOCs) often rely on learner-learner interaction as a mechanism to promote learning. However, little is known at present about learner-learner interaction in these nascent informal learning environments. While some studies have explored MOOC participant perceptions of learner-learner…

Polymer nomenclature is important because it is part of the language of polymer science and is needed for polymer identification, reference, and documentation. A primer on polymer nomenclature is provided herein for people new to the field or for instructional use. Both structurebased and source-based nomenclatures, together with trivial and trade…
