This laboratory experiment consists of the synthesis of two series of alkaline-earth titanates (calcium-strontium and strontium-barium)to corroborate Vegard's law by obtaining their X-ray diffraction patterns and plotting the lattice parameter versus mole fraction of both cations. This experiment allows students to understand the key concepts in…

Within the eukaryotic cell, the actin cytoskeleton is a crucial structural framework that maintains cellular form, regulates cell movement and division, and facilitates the internal transportation of proteins and organelles. External cues induce alterations in the actin cytoskeleton primarily through the activation of Rho GTPases, which then bind…

Previous research on student argumentation in the chemistry laboratory has emphasized the evaluation of argument quality or the characterization of argument structure (i.e., claims, evidence, rationale). In spite of this progress, little is known about the impact of the wide array of factors that impact students' argumentation in the undergraduate…

The teaching of laboratory skills to undergraduate students is central to all experimental sciences. In this setting, students must understand the experimental procedures as well as the fundamental principle(s) being demonstrated, all while learning within a limited time. Other limiting factors include access to equipment and reagents, resulting…

A research-style laboratory experiment for advanced undergraduate students is described, which includes the synthesis, characterization, and properties (porosity, stability, amphipathy) testing of the composite [Cu[subscript 2](BTC)[subscript 4/3](H[subscript 2]O)[subscript 2][subscript 6][HPW[subscript 12]O[subscript 40]·(C[subscript…

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 purpose of this study is to investigate and compare the effects of laboratory experiments and argumentation-based science teaching on science process skills, metacognitive awareness levels, and attitudes towards the science of 4th-grade elementary school students. In this study conducted according to the quantitative research method, a…

The Kicking Mule Brewing Co. at West Point enables members of our chemical engineering club, students, and beer enthusiasts alike to acquire chemical engineering acumen, knowledge, and skills by developing a tangible product. Through a rigorous on-site brewing process with subject matter experts, our goal is enhancement of student chemical…

In a technology-enhanced learning environment and underpinned by a unique hybrid pedagogic model that borrows from gamification, constructivism, and experiential learning approaches, badges were purposefully used to foster engagement. This approach promoted the development of a mindset that identifies and appreciates the worth of a portfolio of…

This innovative comprehensive experiment is a compulsory course for third-year undergraduate students in the eight-year training program leading to a Doctor of Medicine degree or Doctor of Philosophy degree at Peking University Health Science Center (PKUHSC). There is a critical educational need to prepare these students for the increasing…

The study aimed to identify the effect of the interactive drills using the dry laboratory on the acquisition of scientific concepts and laboratory skills in science among the ninth-grade female students in Palestine in light of their thinking styles. The study used quizzes of experimental method. The sample consisted of 68 female students…

Due to the coronavirus lockdown, home experiments were devised for our first-year physics lab course. In this practitioner contribution we elaborate on the guided inquiries that were set up. Students could carry out the experiments with standard tools available at home, including sensors mobile phones are equipped with. Various design principles…

Developing scientific reasoning (SR) is a central goal of science-teacher education worldwide. On a fine-grained level, SR competency can be subdivided into at least six skills: "formulating research questions," "generating hypotheses," "planning experiments," "observing and measuring," "preparing data…

The present study aimed to determine the impact of argument-based laboratory method on the scientific process skills of pre-service primary school teachers and their views on the nature of science. The study was designed based on the pretest-posttest quasi-experimental method and conducted with 64 sophomore pre-service primary school teachers (37…

Allelopathy plays crucial roles in invasive plant viability and agricultural production systems. However, there is no well-established hands-on learning activity to teach the concept of allelopathy. Nor is there an activity which allows students to gain knowledge about glucosinolates and their corresponding enzyme, myrosinase, which are present in…
