The objective of this study was to examine the effectiveness of blended physics laboratory experimentation on pre-service physics teachers' (PSPTs') understanding of the nature of science (NOS) during an electricity and magnetism laboratory course. The study used a non-equivalent comparison group using a pre-test-post-test quasi-experimental…

At Kansas City University, anatomy laboratories were delivered via remote (REM) or on-campus (OC) formats due to COVID-19, creating an opportunity to evaluate student perceptions of differences in laboratory delivery format. A six-item survey of Likert scale and open-ended questions explored the utility of anatomy software, prelab instruction…

This study investigates the challenge faced by eighth-grade students at Southern State Middle School in grasping abstract concepts within the domains of physical science, physics, and chemistry. This difficulty is manifested in their poor performance on summative assessments. A comprehensive analysis of state-provided data, in conjunction with…

The Clemmensen reduction is a common example of a reaction demonstrating the deoxygenation of carbonyl groups, which is a topic that has been widely studied in the field of organic chemistry. The use of trimethylchlorosilane, as a substitute for concentrated hydrochloric acid, allows for the reduction of carbonyl groups. The Clemmensen reduction…

Hands-on learning activities enhance course outcomes in college courses based on increased exam scores and student satisfaction; however, online courses pose challenges for creating hands-on learning opportunities. The objective of this study was to compare online and on-campus students' perception and performance on a soybean processing and…

The supplementation of lecture-based anatomy teaching with laboratory sessions, involving dissection or anatomical specimens, is commonly used. Hands-on dissection allows students to handle instruments correctly while actively exploring three-dimensional anatomy. However, dissection carries a potential risk of sharps and splash injuries. The aim…

Basic Human Anatomy at Indiana University is a large undergraduate anatomy class with nearly five hundred students in twelve lab sections. In the fall of 2018, we added the Virtual Human Dissector software on an interactive Sectra table to our lab to help students fill the gap between idealized anatomical models and fully prosected cadavers. We…

In this laboratory experiment, the synthesis and characterization of H[subscript 5]PV[subscript 2]Mo[subscript 10]O[subscript 40]@Cu[subscript 3](BTC)[subscript 2] (denoted as NENU[subscript -9], H[subscript 3]BTC = 1,3,5-benzenetricarboxylic acid) and its application in fuel desulfurization were performed. This experiment is designed for advanced…

We investigated physics students' behavior in a second-year laboratory by analyzing transcribed audio recordings of laboratory sessions. One student group was given both a problem and procedure and asked to analyze and explain their results. Another was provided with only the problem and asked to design and execute the experiment, interpret the…

Research on student argumentation in chemistry laboratories has mainly focused on evaluating the quality of students' arguments and analyzing the structure of such arguments ("i.e." claims, evidence, and rationale). Despite advances in these areas, little is known about the impact of activity framing on the nature of student…

Induced seismicity has received a lot of attention in recent years. This new natural phenomenon appeared as a result of active human influence on nature. The phenomenon has been detected in places of natural gas and oil recovery, and geological storage of CO[subscript 2]. One of the main reasons for the observed seismic activity is associated with…

This paper provides seven topics on sodium hydrogen carbonate (NaHCO[subscript 3]) and its ions for readers looking for familiar material phenomena to strengthen students' understanding of the chemical concepts of thermodynamics. The first concept is the ideal gas law, followed by the van't Hoff equation, Gibbs energy, pH change, chemical…

Infrared (IR), or radiation, thermometers are widely used in temperature measurements in many different sectors from health, food, automotive, agriculture, iron and steel to chemistry due to their fast measurement capabilities, reasonable prices, wide measurement ranges and ease of use. IR thermometers work based on black body radiation. In this…

We designed and tested a 3D motion tracking system which displays acquired and derived data using augmented reality. This setup, based on a virtual reality headset and its controllers, is a relatively low-cost, high-precision, six degrees of freedom, high-speed, multiple-objects tracking device. This apparatus proves to be a very high-quality…

This study examined whether answering focused explanative questions during pauses in an immersive virtual reality (IVR) lesson on pipetting procedures could enhance learning. The goal was to take a generative learning activity, known to be effective for declarative knowledge with conventional media, to the context of procedural knowledge with…
