The reconstruction of two-dimensional (2D) slices to three-dimensional (3D) digital anatomical models requires technical skills and software that are becoming increasingly important to the modern anatomist, but these skills are rarely taught in undergraduate science classrooms. Furthermore, learning opportunities that allow students to…

Teachers' beliefs such as pedagogical beliefs, self-efficacy, and technology value beliefs are influential to technology integration practice. This study aims to investigate teachers' beliefs and the impact on their 3D printing integration in science classrooms. A total of 26 K-12 teachers across six states in the U.S. participated in a nationally…

Tangible teaching aids can provide a valuable supplement to traditional textbook-based learning of fundamental STEM concepts. 3D-printed templates detailing the construction of simple parallel and series circuits were incorporated into the lesson plans for 6th-grade introductory physics. Aiming to introduce the concepts of junction and loop rules…

We present the design of a periscope-type VIS spectrometer for educational purposes that combines strong features from various earlier designs and adds new ones. Three 3D-printed pieces that hold a small thin mirror sheet, a 1/8th wedge of a DVD, and two razor blades are easily assembled and facilitate insight into its construction. A new feature…

Due to immense cost reduction and routine commercial availability, 3D printing has become the cutting-edge technology with enormous potential--also for educational and applied chemistry. It opens the opportunity to print custom-made reactors, such as (micro) flow reactors. In addition, 3D-printing technology can simplify chemical reactions, such…

Undergraduate physics laboratory exercises are very important in shaping students' attitude to science, especially for future teachers. Recently, it is necessary to look for ways to easily create large quantities of experimental sets, not only for institutional use, but also for sets that can be produced in large quantities and distributed for use…

An increased reliance on nanotechnology and recent developments in materials fabrication coincide with a greater prevalence of 3D printers in high schools. We developed this lesson to foster an exploration of interdisciplinary fields and to increase access to recent advances in materials chemistry through two different learning modules. The lab…

This work presents a homemade multirole 3D-printed modular spectrometer(MPMS), which can be easily assembled like bricks and expanded with several modules to measure different types of spectra, such as UV-vis absorption, fluorescence emission, flame emission/absorption, glow discharge, and even Raman spectra. The spectrometer is designed to be…

3D printers have facilitated a wealth of 3D printed molecular models illustrating key structural concepts for student learning. However, general adoption of 3D printed models in the organic chemistry classroom proceeds slowly as the majority of consumer-grade 3D (fused deposition modeling (FDM) and resin) printers are inherently monochromatic,…

Topographic maps are a common form of 3D surface elevation data represented as a 2D display. Despite their use in geoscience courses, many students find learning to effectively read and interpret these maps challenging. Here, we present a tool for teaching topographic map interpretation using 3D printed terrain. The terrain was 3D printed from a…

Experiments involving electrochemical cells are of great pedagogical value for learners of introductory chemistry. This paper discusses an improved experimental kit made from a 24-well cell culture plate and a 3D-printed scaffold. The current design focuses not only on the accuracy of the result but also on the intuitiveness of the wiring work and…

This study examines the effect of teaching with the STEM Cycline of the 'Force and Energy' unit on students' creativity, metacognitive awareness, and academic achievement. The nonequivalent control group design, one of the quasi-experimental models, was used in the study. The study included 54 seventh-grade students studying at a public school in…

The electrolysis of water to produce hydrogen is a critical step in many green chemistry processes. The key to the efficiency of water electrolysis is the synthesis of an appropriate electrocatalyst. Three-dimensional (3D) printing is an increasingly important part of many industrial processes. In this study, we propose an efficient laboratory…

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…

3D printing and simple electronics were used to create a polarimeter suitable for a variety of chemistry courses. This device allows instructors to demonstrate optical activity but is also easy to use and low cost enough to be widely available for student use, as well. The instrument uses an LED light source and detector housed in a 3D-printed…
