A laboratory is a large investment of time and money for departments of chemistry yet discussions continue about its purpose in the educational process. Helping students navigate the three levels of representation; macroscopic, particulate and symbolic is a potential use of this time. This study looked at two different types of visualization for…

Wave physics phenomena can be observed in everyday life and represent a fundamental prerequisite to many domains of classical and modern physics. Lots of studies demonstrate that novices have to face important learning difficulties in approaching this topic. The study of string vibrations' modes allows an educational introduction to basic…

The interface of art and science provides a broad range of educational and collaborative projects at various learning stages. Therefore, the use of historic artists' materials for teaching chemistry is receiving more attention. We prepared and used copper acetate (verdigris pigment) for a series of interconnected, lab-based activities, which can…

This article showcases how a physics lab course was successfully redesigned to promote important reasoning abilities not explicitly addressed in the typical college setting. Student development of such abilities is essential for sound decision making, particularly when living in an information age. Essential features of our guiding curricular…

The development of expertise in chemical information literacy requires practicing these skills in the context of chemistry work. The integration of information literacy in problem-based learning is an instructional strategy that can be used to situate skill development in the chemistry classroom. This work describes a mixed-methods approach to…

Scientific writing, in the form of lab notebooks, proposals, and reports, is a common element of physics lab classes. Multiweek student-designed projects are growing in popularity, especially in advanced lab courses, and writing may play a unique role in these types of courses. In prior work, we developed a framework of possible goals for writing…

Students and instructors bring varying levels of experience and expectations to online learning. This became even more apparent in March 2020 when the pandemic disrupted face-to-face instruction and required rapid conversion to remote teaching. In this study, mixed methods were used to understand how students perceived these instructional changes…

The main purpose of this study is to determine the perceptions of elementary school students (1,2,3 and 4) about science and scientist. The study has been included three different elementary schools in the city center of Kastamonu in northwest Turkey. A total of 1862 students in the first (n = 480), second (n = 450), third (n = 471) and fourth (n…

Faculty in the Department of Chemistry and Physics at the University of New England (UNE) have recently transformed introductory and advanced chemistry curricula by embedding the high impact practice of undergraduate research. Course Based Undergraduate Research Experiences (CUREs) have provided experiential learning opportunities for over 272…

Lab orientation is a vital part of learning for new students entering the university, as it provides the students with all the necessary and important information about the lab. The current orientation is manual, tedious, suffers from logistical constraints, lacks engagement, and provides no way to assess that outcomes have been achieved. This is…

Inquiry-style laboratory courses, in which students engage in open-ended projects rather than a prescribed set of experimental steps ("cookbooks"), are becoming increasingly popular at the undergraduate level. Reformed curricula require reforms in training teachers; in the case of large universities, laboratory instructors are typically…

Student belongingness is important for successful study paths, and group work forms an important part of modern university physics education. To study the group dynamics of introductory physics students at the University of Helsinki, we collected network data from seven laboratory course sections of approximately 20 students each for seven…

Aim/Purpose: The objective of this study is to explore the effectiveness of using virtual experiments on students' level of achievement and on their practical skills as well as their views on applying the virtual experiments in a general physics lab. Background: There is a continuous debate in the literature on the effect of using virtual…

Clustered regularly interspaced short palindromic repeats (CRISPRs) represent a novel type of adaptive immune system found in eubacteria and archaebacteria. CRISPRs have recently generated a lot of attention due to their unique ability to catalog foreign nucleic acids, their ability to destroy foreign nucleic acids in a mechanism that shares some…

Since at least the 1960s, organic chemistry textbooks have featured pK[subscript a] tables for organic acids that include values for H[subscript 2]O and H[subscript 3]O[superscript +] (15.74 and -1.74, respectively) that are thermodynamically and chemically indefensible. Here we trace this error back to Brønsted's early contributions in the 1920s…
