An augmented reality (AR) application that complements a DNA precipitation experiment has been developed for use on mobile devices. The AR experience provides atomistic detail on the reasoning behind the experimental observations. The development of the application is described, as are the download data. In a pilot survey, the students were asked…

This paper demonstrated a simple experiment for determining the coefficient of rolling friction of a hollow cylinder rolling on a curved track using a smartphone's sensors. We studied theoretically and experimentally the rolling motion of a hollow cylinder uncovered and covered with various materials (synthetic leather and sponge sheets). The…

A lack of preparedness for college-level coursework has been shown to negatively impact student success rates in STEM. Remedial instruction has been the most widespread approach to helping at-risk students attain college-level competencies; however, studies have shown that remediation has had null or negative impacts on degree completion for…

Chemical waste should be reduced to minimize environmental pollution, and it is important that the amount of waste is minimized in chemistry teaching laboratories to reduce the negative impact on environment as well as the disposal costs of university. There are several ways to minimize the waste generated in chemistry teaching laboratories,…

Although demonstrations play a central role in teaching and learning chemistry, the effects of concrete setup principles have rarely been subject to systematic empirical studies. According to the left-to-right principle, the educator should begin with the first step of a reaction in the upper left part of the setup and then place the following…

The 21st century and industry revolution 4.0 has been technology used part of life. This research intended to understand the effect of android application for chemistry learning (reaction rate material) to construction of motivation and metacognition of high school students. Research aimed to determine the worthiness and effectiveness of chemistry…

Although new teachers clearly need resources and support, little is known about the types of resources new science teachers' access during their early years of teaching. To increase knowledge of their needs, the study described in this article focused on the primary resources (i.e., human, material, and social) and secondary resources (i.e.,…

This study aims to (1) determine the difference between the improvement in students' self-regulation skills before and after the implementation of the GITTW learning strategy, and (2) describe students' perception of the skills of selfregulation before and after the implementation of the GITTW learning strategy. This is pre-experimental research…

In this brief experiment, students create a superhydrophobic surface as an application of polar--nonpolar interactions and redox chemistry. Half of a zincgalvanized steel strip is coated in copper nanoparticles through electroless deposition. A layer of nonpolar octadecanethiol is added to half of that copper surface. Students classify the three…

Experimental electrochemistry offers unique opportunities for interactive instruction at all levels of education; however, widespread adoption in curricula is hindered by high costs associated with electrochemical instrumentation. Thus, the development of affordable instruments represents an essential step toward making electrochemistry accessible…

A quasi-experimental treatment control group design was used to investigate the effect of a conceptual change curriculum, Multi-Step Inquiry approach, on students' perception of their learning in a science classroom. This started with the development of a workbook that explicitly focused on conceptual understanding, followed by the development and…

The transition from elementary school to the upper grades can lead to ambiguous feelings toward the new, male teachers. This study investigated whether collaborative animal care in biology lessons affects students' feelings of relatedness toward their biology teachers positively during the first year after the school transition. Four hundred…

A chemistry course designed as an elective for chemistry, biochemistry, biology, and pharmaceutical science majors is described. The course is designed for second- through fourth-year undergraduate students. The prerequisite is first-semester, second-year undergraduate organic chemistry with the second semester of the organic sequence as a…

Physics faculty care about their students learning physics content. In addition, they usually hope that their students will learn some deeper lessons about thinking critically and scientifically. They hope that as a result of taking a physics class, students will come to appreciate physics as a coherent and logical method of understanding the…

In recent years, there has been an increased interest in conceptual blending in physics and mathematics education research as a theoretical framework to study student reasoning. In this paper, we adapt the conceptual blending framework to construct a blending diagram that not only captures the product but also the process of student reasoning when…
