Students need procedural understanding--that is, knowledge of the procedures that scientists use to establish scientific evidence (also known as "concepts of evidence"), to successfully perform scientific investigations, and to evaluate public and scientific claims. However, concepts of evidence are seldom explicitly targeted in routine…

With the continued spread of the COVID-19 crisis, the universities were closed temporarily in Turkey just as in the rest of the world. As a result of this, many educators and students tried to adapt online education quickly. This research study examined 67 pre-service teachers' views on online chemistry laboratory learning experiences amid the…

A new teaching assistant model was adopted and qualitatively assessed for the general chemistry laboratory, in which both an undergraduate and a graduate teaching assistant provided instruction to students during the lab. Verbal interactions between graduate and undergraduate teaching assistants were recorded, transcribed, and coded using the…

As a cross-cutting and comprehensive subject, medicinal chemistry involves the knowledge of chemical, biological, medical, and pharmaceutical sciences. A comprehensive medicinal chemistry experience for undergraduates is expected to train various experimental skills and enhance their scientific research ability. Herein, a series of laboratory and…

The dehydration of 2- or 4-methylcyclohexanol to obtain isomers of methylcyclohexene is a classic organic chemistry experiment. Students perform a distillation, collecting samples to analyze the progress of the reaction. The reaction produces a major product that can be explained on the basis of the regiochemistry of the [pi] bond formation for…

The amplification of nucleic acids is a fundamental tool utilized in various scientific disciplines, including Molecular Biology, Immunology, Microbiology, and Genetics. However, due to the time and technology required for traditional polymerase chain reaction and its derivatives, it is not always possible to include such methodologies in…

The COVID-19 pandemic led to an abrupt suspension of face-to-face teaching activities in higher education institutions across the globe. The instructors and faculty at most institutions have had to adapt, invent, and implement adjustments quickly to adopt an online learning environment. This has been an extraordinarily challenging time for both…

The calcium hydroxide solubility product constant ("K"[subscript sp]) lab is a familiar lab experiment outlined in the "Advanced Chemistry with Vernier" handbook. In an on-campus laboratory setting, students are afforded the opportunity to examine techniques, such as titration of a saturated base solution (Ca­(OH)[subscript 2])…

A study with K-9 Greek students was conducted in order to evaluate how the declarative knowledge acquisition was affected by incorporating Arduino experiments in secondary Chemistry Education. A Digital Application (DA) that blends the use of the Arduino sensors' experiments with digital educational material, including Virtual Labs (VLs), was…

We describe an educational activity that can be done by using smartphones to collect data in physics experiments aimed to measure the oscillating period of a spring-mass system and the elastic constant of the helicoidal spring by the dynamic method. Results for the oscillating period and for the elastic constant of the spring agree very well with…

Research mentors can play an active role in helping their students develop oral communication skills by implementing formative assessment activities in their group meetings. A rubric can be used as a formative assessment tool that helps a student understand the achievement target they are working toward, where they are relative to the achievement…

Grades influence students' confidence and decisions to complete STEM degrees and pursue relevant careers. What affects students' confidence and performance in college upper-division biology laboratory courses and how relevant are evaluation methods to career success? STEM laboratory courses are an excellent model to address these issues because of…

Introductory physics lab courses serve as the starting point for students to learn and experience experimental physics at the undergraduate level. They often focus on measurement uncertainty, an essential topic for practicing physicists and a foundation for more advanced lab learning. As such, measurement uncertainty has been a focus when studying…

The COVID-19 pandemic has led to an increasing amount of research on redesigning educational models. This paper describes the contents of a new laboratory course on physical chemistry based on blended learning, designed for third-year students in the Department of Applied Chemistry, Faculty of Science and Engineering, Chuo University. We provided…

An introductory plant science lab offered by the Department of Agronomy & Horticulture at the University of Nebraska-Lincoln was adapted for online delivery. This paper describes the adjustments made for online delivery and examines students' perceptions of learning and engagement from surveys administered in both the in-person and online…
