The American Chemical Society (ACS), Division of Chemical Education, Examinations Institute, has been developing content maps to describe comprehensively the undergraduate curriculum aligned to traditional subdisciplines. These content maps have been developed through the combined efforts of many faculty members who teach the targeted courses in…

A ball at rest on a surface can be made to bounce up by pushing it down then releasing the downward force as fast as possible. Measurements and calculations are presented to show how it can best be done.

In this paper a "non-elementary system" is defined as a system consisting of elementary (i.e., indivisible) constituents. Such systems are a common feature of the standard model of particle physics: for example, according to the standard model, a proton (non-elementary particle) consists of two up quarks and one down quark (elementary…

The abstract nature of physical chemistry and spectroscopy makes the subject difficult to comprehend for many students. However, bridging arts and science has the potential to provide innovative learning methods and to facilitate the understanding of abstract concepts. Herein, we present a high-school project based on the conversion of selected…

An undergraduate organic chemistry experiment has been developed that features asymmetric synthesis of an enantioenriched secondary alcohol, followed by determination of its absolute configuration using the competing enantioselective conversion (CEC) method. Students are given a ketone and an unknown enantiomer of CBS (Corey-Bakshi-Shibata)…

Ecosystems, interacting systems of biotic and abiotic factors, are a fascinating topic in life science. The "Next Generation Science Standards" (NGSS Lead States 2013) recognize "Ecosystems: Interactions, Energy, and Dynamics" (HS-LS2) as one of four overarching ideas in life science that students should understand. Student…

We show that the gravitational acceleration g near Earth's surface can be easily determined with high accuracy by conducting the usual free fall experiment in high school or college physics laboratories. Unlike the conventional method of data analysis that uses formulas without taking air resistance into account, we consider the effect of air drag…

Given the rapid pace of science today, we can feel the influence of it in all aspects of our lives. Therefore, it is aimed to raise individuals with advanced thinking skills who learn and use knowledge in science class and can combine science and technology. In line with such purposes, it is believed that different methods and techniques are…

This paper introduces quantum materials and the notion of using models to aid the comprehension of complex ideas. It describes a hands-on activity, collaboratively developed by scientists and artists, that promotes an understanding of how experts take advantage of analogical thinking and model building to develop important frameworks. Quantum…

Difficulties in understanding evolution are often rooted in early childhood, arising from naïve assumptions and cognitive biases. However, literature reviews mainly focus on school and university students' understanding of evolution, with only limited comprehensive reviews on children in early childhood aged up to 7 years. This systematic review…

The achievement of a proper conceptual change is a challenge for students since there are some constraint-based interactions including different ontological categories with the well-known dichotomy of matter or process. To mitigate this state of affairs, more instructional sequences with pedagogical approaches are needed because many students,…

The aim of the research is to provide a general framework for POE used in biology education using meta-synthesis. In this research; studies on the use of the prediction-observation-explanation (POE) in biology education between the years 2000-2020 in Turkey and the World have been examined considering research type, distribution of the studies by…

Abundant prior research has compared effects of physical and virtual manipulatives on students' conceptual learning. However, most prior research has been based on conceptual salience theory; that is, it has explained mode effects by the manipulative's capability to draw students' attention to conceptually relevant (visual or haptic) features.…

Understanding the lifestyle changes that authorities have requested or required in response to COVID-19 requires some biological knowledge. Therefore, articulations of intended biology learning at the school level will need to be evaluated, to see if they continue to be fit for purpose in light of the pandemic. This article proposes two principles…

Enzymes are widely applied in different industries, like pharmaceutical, food, biofuel, and waste valorization. However, the enzyme operating conditions are very limited. So, in most industrial processes, enzymes are not efficient, due to the use of harsh conditions, like organic solvents, extreme pH, and temperature. Immobilization arises as a…
