The increasing availability of digital tools in science classrooms can provide students with more frequent and easier access to large amounts of data. Large data sets have considerable epistemological potential, as they enable, for instance, the observation of otherwise unobservable phenomena, but it must be assumed that handling them places…

Professional experiments in genetic research usually start in a class at university. However, interest in genetic research techniques from an early age is essential. We have continuously performed a short genetic experimental course for high school students using a simple molecular experiment and computer-based learning for Mendelian inheritance.…

It is well known that allowing students to put theory into practice is beneficial to consolidate knowledge and to better memorise the topics that are discussed in class. Furthermore, practical work is a valuable asset to stimulate students' attention and represents one of the keys to the success of the scientific experience in school. Didactic…

This paper shares an account of our wonderings, happenings, and learnings emerging from encounters between children, iPads, digital microscopes and found natural materials (and bugs!) in a series of workshops at a children's museum. Our intention is to build on and disrupt established theories about children's museums by thinking differently and…

This work explains the strategies in implementing an undergraduate Honors project focusing on the evaluation of learner achievement in Organic Chemistry I Laboratory. The primary objective of this research was to assess learner achievement in the Organic Chemistry I Laboratory. The purpose of this research was to determine if any adjustments…

Improving students' views of experimental physics is often an important goal of undergraduate physics laboratory courses. However, traditional lab courses typically include highly guided activities that often do not require or encourage students to engage in the authentic process of experimental physics. Alternatively, open-ended activities in lab…

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 introduces a small-scale chemistry practicum technique with the concept of acid-base identification, determination of pH with indicators, and neutralization reactions with the concept of titration. The first experiences of teachers and students in small-scale chemistry practicums are revealed. Action research was carried out to…
