Upper-division undergraduate students are introduced to polymer processing using material extrusion fused filament fabrication 3D printing to make poly(lactic acid) (PLA) mechanical testing specimens. Computer aided design and slicing software packages are used to demonstrate the process of preparing 3D computer models for printing. Following the…

In this randomized control study, we evaluated science teachers' pedagogical practices via classroom observations following ongoing, intensive, and structured instructional support sessions. These sessions included virtual professional development (VPD) and virtual mentoring and coaching (VMC) that accompanied a literacy-infused science…

Teachers are increasingly expected to incorporate Project-based learning (PBL) pedagogy to teach science. While teachers' definitions and challenges in the use of PBL are widely studied, very few studies focus on the development of a teacher's knowledge of the use of PBL over multiple projects. The current research is an in-depth case study aimed…

The study aimed to determine science lesson-focused responsibility levels of primary school students in terms of various demographic variables. This study used a quantitative research methodology and a descriptive survey model, one of the general survey models. The research was conducted in three central districts in Kayseri province, Türkiye, in…

There is an expanding body of research focused on exploring inclusive science learning for students with complex support needs. The aim of this qualitative case study was to explore how a research partnership focused on expanding inclusive science learning for students with complex support needs (CSN) could support the learning of a focal student…

The ability of students' creative thinking is not well developed by learning that only focuses on convergent thinking training without giving students problems to face. Therefore, students have difficulty in developing creative thinking ability. Therefore, it is necessary for a learning program to improve student creative thinking ability. This…

The Curie temperature, also called the Curie point, is the temperature at which magnetic material undergoes a phase transition from ferromagnetic to paramagnetic properties. The characteristics of permanent magnets appear below the Curie temperature--below 400 °C (673 K) for commercial ferromagnetic materials such as ferrite or neodymium. In…

This paper describes a method to demonstrate that the plane of the lunar orbit around Earth and the plane of the ecliptic (the plane of Earth's orbit around the Sun) are inclined with respect to each other, and to present a method for measuring the angle of the inclination. The angle between the diameter of the Moon's orbit when the Moon passes…

Resistor-capacitor (RC) circuits are a popular topic for both theoretical discussion and experimental investigation in introductory physics. This article presents a novel approach to studying such circuits using a piezoelectric buzzer. A capacitor is discharged through a resistor and the buzzer, and the intensity of the sound produced by the…

The American Association for the Advancement of Science (AAAS) has outlined four themes that define science literacy; these are systems, models, constancy and change, and scale. More recently, the National Research Council has released the framework for K-12 science education that includes "Scale, Proportion, and Quantity". Scale…

The action of hammering a nail into wood is examined in terms of the force, momentum and energy required. Some unexpected experimental results are also presented.

Flavor plays a crucial role and is the most important aspect of foods and beverages. [Beta]-Ionone is a common flavor compound with a characteristic violet-like odor. An undergraduate flavor compounds chemistry laboratory that provides preparation and characterization of the flavor compound inclusion complex between…

College physics textbooks (algebra based) tend to shy away from topics that are usually thought to require calculus. I suspect that most students are just as happy to avoid these topics. Occasionally, I encounter students who are not so easily satisfied, and have found it useful to maintain a storehouse of non-calculus solutions for some common…

One theme that both the American Association for the Advancement of Science (AAAS) and the National Research Council (NRC) agree pervades any science course (and specifically chemistry) is scale. Despite the fact that scale concepts and skills are at the core of a student's scientific literacy, scale or the skills related to understanding quantity…

A mechanical model of light propagation helps to show that optical refraction is related to the speed of light and how it changes from one medium to another. A tricycle toy robot is used to realize the model. Left and right wheels independently change their speed (high or low) in response to the local color (white or black, respectively) of the…
