The primary objective of the current project was to convey authentic science to students in out-of-school student laboratories. High school students have diverse and partially wrong concepts of scientists' work. To convey more realistic concepts, we developed videos of scientists working on relevant and up to date scientific topics. These videos,…

In 2018, to help undergraduate medical students strengthen their self-learning and scientific research skills, we introduced an instructional model that combined literature-based learning with experimental design. We tested this model on the molecular biology class at Tongji University. In the first step of the model, a topic is chosen, and…

Remote access technology in STEM education fills dual roles as an educational tool to deliver science education (Educational Technology) and as a means to teach about technology itself (Technology Education). A five-lesson sequence was introduced to 11 and 12-year-old students at an urban school. The lesson sequences were inquiry-based, hands-on,…

This article seeks to provide researchers and practitioners in laboratory education, particularly those involved in the curriculum design and implementation of teaching laboratories at university level, with a conceptual framework and a working model for an integrated assessment of learning domains, by attending to a more holistic approach to…

Smartphone-based experimental exercises were incorporated as part of the homework problems in an introductory mechanics course at a university. A quasi-experimental field study with two cohorts design was performed to measure the impact of such exercises on motivation, interest and conceptual understanding. The empirical results on learning…

The primary learning objectives of this "Next Generation Science Standards" (NGSS; NGSS Lead States 2013) aligned activity is to help high school biology students experience firsthand the role of replication in scientific inquiry and food preference as a behavioral reproductive trait of the Madagascar hissing cockroach. The secondary…

Here, students determine aspirin (acetylsalicylic acid) mass in pharmaceutical tablets using a colorimetric method. Aspirin, salicylate, and salicylic acid do not absorb visible light. Thus, in alkaline medium, acetylsalicylic acid was hydrolyzed to salicylate; then, it was reacted with an acidic Fe(III) solution, and a violet complex was formed.…

Micellar catalysis has become an important aspect of the chemical industry's effort to "go green". However, this chemistry has yet to be fully explored in educational settings such as second-year organic chemistry laboratories. Reported herein is a discovery-based nucleophilic aromatic substitution experiment that introduces chemistry…

Describing the motion in a vertical roller coaster loop requires a good understanding of Newton's laws, vectors and energy transformation. This paper describes how first-year students try to make sense of force and acceleration in this example of non-uniform circular motion, which was part of a written exam. In addition to an analysis of the exam…

This article describes an experiment that can be done in the classroom in a simple way, with the support of a "homemade" device or as a laboratory practice with the support of PASCO equipment. Through a theory-practice sequence, kinematic and dynamic equations were checked with qualitative and quantitative analysis, emphasizing the…

The effects of substitution on reaction rates are at the heart of both physical chemistry and organic chemistry. In this paper, we present a computational laboratory module to explore the effects of group substitution and isotopic substitution on reaction rates by using a readily accessible graphical interface, a computational engine, and…

In the field of physics teaching, the simple pendulum provides a very simple way to study the harmonic oscillator, the source of some fundamental concepts such as periodicity, relaxation time and anharmonicity. As such, its experimental study is frequently integrated into high school or first year university programs. With this in mind, in this…

Earlier studies have discussed the usefulness of storytelling and hands-on activities when teaching young children science. However, few studies have investigated the use of the two methods in combination. This study reports on five pre-school teachers' experience of combining storytelling and hands-on activities in teaching science and their…

Contribution: This article aims to explore learner variables that predict the effectiveness of university class using the Havruta method. Background: This article was conducted on 105 learners enrolled in the "General Physics and Experiments 2" class at K University in South Korea. Research Questions: Independent and dependent variables…

This modular, open-framework capstone course delves deeply into the synthesis, separation, and characterization of chiral molecules while teaching critical thinking and writing skills in a research-like setting within a fertile area for discovery. This course has evolved over 30 years and has been in its present form for 5 years at the time of…
