Blood pressure regulation keeps us alive, yet its underlying mechanisms often remain abstract for students. Heart rate, stroke volume, vascular resistance, and compliance interact continuously to shape arterial pressure, but in many classrooms, these variables feel disconnected from observable outcomes. To bridge this gap, we developed a simple,…

Light and its spectrum are central concepts in many introductory physics, astronomy, geology, and conceptual physics courses. The Sun and its spectrum are usually primary examples, likely due to the Sun's everyday familiarity and the full spectrum it generates when dispersed. To enhance such discussions with a hands-on student activity, we've…

This study sought to use simple, less costly, robust equipment and constructivist pedagogies, that promote and foster learning, to enable an intact class of 81 teacher trainees in a teaching programme to form their own authentic concepts through fun-filled, engaging social interactions. Data were collected by means of two-tier diagnostic…

A simple hands-on model for illustrating the concept of isotope dilution analysis (IDA) has been devised. The model consists of two sets of beads of different sizes, with one set representing atoms of the analyte and the other set representing solvent water molecules. Phase separation is mimicked by sieving the beads, and the results are detected…

There are relatively few studies examining cooperative learning during laboratory activities in a science museum. This study aims to explore such activities to better understand the nature of cooperative learning, if any, in that setting. The participants in this study were 60 fourth-grade students who visited a science museum lab as part of a…

This laboratory experiment aims to provide undergraduate students with research experience in water treatment by membrane separation. This experiment includes fabrication and characterization, as well as water treatment applications of the interfacially polymerized polyester nanofiltration membranes. Through participating in this experimental…

Removing the pollutants from various wastewater is crucial to the environment, ecology, and humans. However, the pollutants are generally removed by chemical decomposition, which not only consumes a lot of energy but also produces carbon emissions. Electrochemical flocculation is effective to extract pollutant molecules and heavy ions from…

Background: With the rapid proliferation of online education, it is incumbent upon teachers to find ways to provide online students with science laboratory experiences. Existing research on online labs focuses heavily on computer-supported inquiry learning environments, such as virtual laboratories and remote laboratories. There are limited…

Biomedical engineering (BME) is a multidisciplinary, constantly advancing field; as such, undergraduate programs in BME must continually adapt. Elective courses provide opportunities for students to select topic areas relevant to their interests or future careers. Specifically, laboratory courses allow experiential learning in specialized topics…

Electroanalytical chemistry has been advanced through portable devices, providing methods and sensors for the detection of analytes with high sensitivity and accuracy. This subfield of electrochemistry has the potential to be utilized in industry and analytical quality control, in general. This results in an increasing demand for trained…

In analytical chemistry, discussing different method sand techniques of analysis is essential to promote critical thinking and reasoning. Analytical courses in the chemist, pharmacist, and biochemist curricula represent the opportunity to study concepts such as experimental design, sampling, development, and optimization of protocols, data…

Collaborative programs are essential to fully engage and educate all who interact with the environment. Existing place-based programs targeting the care of Hawai'i's land and oceans rarely simultaneously engage the tourism industry and local communities. To address this gap, researchers from the Hawai'i Institute of Marine Biology developed a…

Educators have a plethora of teaching methods that allow them to tailor the learning environment to meet students' needs. One novel instructional approach that has grown in popularity in U.S. higher education has been the flipped classroom approach, which has become a popular way to embrace a student-centered learning environment. Of the various…

Hands-on activities promote interest in engineering, but their use in primary education is under pressure due to doubts about their effect on learning. Based on the Challenge Point Framework, we hypothesized that an adaptive approach in which a pupil starts with tasks at its level of prior knowledge would raise the learning results of hands-on…

A disadvantage that A&P classrooms using 3-D digital computer anatomical models experience is the disconnect between digital and physical models traditionally used. This project used 3-D digital models on smart tablets and traditional physical models for in-class A&P lab practical exam studying and preparation. We focused on the hands-on…
