This study aims to investigate the effect of the Project-based Learning (PjBL) learning model and class differences based on online learning settings (synchronous, asynchronous, and mixed) on the analytical abilities of the Discovery Learning (DL), Interactive Demonstration (ID), and Inquiry Lessons (IL) models after adjusting for IQ of…

The transfer of electrical energy without any electric leads or cables is not only a modern subject of research, but the technology has already found its way into our daily lives. Especially in consumer electronics a lot of applications are commercially available, mostly non-contact charging applications for toothbrushes, mobile phones, etc. On…

This research aimed to measure the coefficient of restitution (COR) for tennis and golf balls using smartphone sensors. The ball and smartphone were attached at the ends of a long plastic strip: one end was a pivot with the attached smartphone and another end was for the attached ball. The ball on the plastic strip was swung to bounce the ball.…

Examples are an essential part of mathematics teaching and learning, used on a daily basis to teach and practice content. Yet, selecting good examples for teaching is complex and challenging. This article presents ideas to consider when selecting examples, drawn from a research study with algebra 2 teachers.

This paper reports results from a mixed-methods intervention conducted in partnership between a faculty member and an undergraduate to shape student study strategies for success in an introductory course. The instructor provided students with information on the effectiveness of the successive relearning study strategy, conducted an in-class…

Purpose: Knowledge exchange networks are critical to farmer success and help reduce barriers to entry and growth for new farmers. This study explores informal and formal knowledge exchange networks among two growing industries in Maine: maple syrup production and beekeeping. We increase understanding of the mechanisms through which knowledge…

The Ball Bearing High Voltage generator is a fairly simple and transparent apparatus that can serve as a tool to motivate conceptual descriptions and calculations in electrostatics that are normally presented to our students in a rather dry and matter-of-fact fashion. For example, instead of posing a problem in the typical textbook form of…

Retrieval practice has been widely studied as an effective strategy for enhancing memory. In this review article, we discuss how its effects on learning complex problem-solving procedures are less straightforward, however, with repeated studying of worked examples sometimes more effective than problem-solving practice. This worked example benefit…

Cognitive load can play a key role in learners' abilities to solve complex problems like mathematics. Many factors can affect the presence of cognitive load in learning including instructional strategy, task difficulty and prior knowledge. To understand the interaction of above factors and their influence on learner cognitive load and performance,…

Colorblind ideology provides individuals with numerous ways to minimize racism. This poses a challenge for instructors who teach about race and racism as students deploy this ideology to derail classroom discussions. Student resistance may be amplified when discussing microaggressions because students often characterize focusing on…

Nearly every introductory physics or chemistry course includes live lecture demonstrations, which can range from simple illustrations of a pendulum to elaborate productions with specialized apparatus and highly trained demonstrators. Students and instructors often consider "demos" to be among the highlights of these classes. Yet, in some…

The teaching of wave physics has developed over the years, including devices that demonstrate water waves being used effectively for a long time. However, it was not easy to select and display the wave frequencies. This research had developed a DIY Ripple Tank experiment set using a smartphone application to measure the properties of water waves.…

Augmented reality (AR) is a means of superimposing artificial 3D objects over the real world via a mobile device. An AR standard file format has been recently implemented on mobile devices that current students commonly own. Here we describe three relatively nontechnical methods to produce 3D AR objects for chemistry courses and demonstrate their…

This laboratory experiment visually demonstrates the advanced scientific concept of aggregation-induced emission (AIE) using hands-on learning methods. The experiment is divided into two parts: the first period consists of synthesis and isolation of the organic compound 2(TPA-O)-TPE using typical organic chemistry lab techniques; the second period…

A surprising phenomenology from a traditional demonstration experiment in Geometrical Optics reveals here an interesting matter of discussion and analysis. Hence, the main focus of this paper is to observe and discuss such an innovative phenomenology.
