Scientific literacy is used as the primary goal in science education because it is considered to be used to prepare today's generation. Aspects of scientific literacy consist of the concepts, processes, and attitudes of science that can be used in people's daily lives, a picture of the success of science education carried out by each country.…

This article reports on a new device, called a geyser guide, that allows for quantitative measurements of both bubble sizes and kinetics of foam production in the so-called Diet Coke and Mentos experiment. The device is easily constructed, is made using readily available materials, and allows the experiment to be carried out indoors with no mess.…

Incorporation of increased flexibility and adaptivity in courses can support freshmen with taking responsibility for their learning process. This is especially beneficial in the case of chemistry courses given their typically abstract nature and associated need for engaging in practice and higher order thinking. Blended learning can be used to…

Does early exposure to information literacy promote long-term student success? This paper describes a longitudinal case study testing the hypothesis that students who engage with scientific literature and develop information literacy early in their undergraduate studies will achieve higher grades on literature-based assignments in future…

Techniques and instrumentation that involve fluorescence are used in many careers related to biology and biochemistry. However, due to the expense of instrumentation, the theory and practice of fluorescence spectroscopy is commonly concentrated in instrumental analysis in most curricula, a class rarely required for biology and biochemistry majors.…

The chemistry teacher pipeline has experienced considerable loss of teachers due to turnover. High turnover rates create localized staffing problems and a revolving door of novice teachers, particularly in the sciences and in urban and rural locales, which impacts student learning and achievement. This non-experimental longitudinal study examined…

In this paper are presented the results of a study regarding the self-perceived assessment skills of Romanian teachers. An instrument regarding the self-perceived assessment skills was applied to N=108 teachers. From the seven factors of the instrument, it was found that the Romanian teachers who participated in this study reported that they are…

Undergraduate organic chemistry students, as they study conformational analysis and stereochemistry, frequently have trouble manipulating three-dimensional structures on a two-dimensional page or screen. The inability to accurately convert three-dimensional bond-line representations into Fischer projections is one example of this. While some…

There have been multiple calls to incorporate the teaching of scientific practices within science laboratory courses over the past decade. To accomplish this goal, changes must be made to the curriculum standards, instructional programs, and assessment-evaluation systems used in laboratory courses. One instructional program that can used in a…

The contemporary Human activity utilizes huge volumes of digital data to solve efficiently multiple socio-economic, scientific and technical problems. Now the big data analysis is mainly oriented to the socioeconomic sphere with a goal to lift the profit. The science and technology to penetrate deeper in the nature of objects and systems under…

Chemistry students often struggle in organic chemistry courses. In fact, these courses are viewed by some as "weed-out" classes. There are many fundamental concepts covered in general chemistry that contribute to students' ability to succeed in organic chemistry. One of those fundamental topics, and the focus of this study, is the topic…

Reading is a complex task that requires integration of information across brain systems that support sensory, language and cognitive processing. Individuals vary widely in reading ability: some read almost effortlessly, while others struggle to make sense of printed text. Factors at multiple levels from genes and brain through environment…

Magnetic iron oxide nanoparticles were synthesized and stabilized using ammonium cations or poly(vinyl alcohol) to produce amazing materials such as safer aqueous ferrofluids, ferrogels, ferromagnetic inks, plastics, and nanopowders illustrating how versatile materials can be produced just by simple modifications. The synthesis is fast, reliable,…

Numerous studies have proven the learning benefits of concept maps in science subjects, particularly for students with low prior knowledge. There is a scarcity of research dedicated to the examination of chemistry courses at the university level, and the findings pertaining to academic performance in that subject exhibit a lack of consistency.…

The Beer-Lambert law is a fundamental relationship in chemistry that helps connect macroscopic experimental observations (i.e., the amount of light exiting a solution sample) to a symbolic model composed of system-level parameters (e.g., concentration values). Despite the wide use of the Beer-Lambert law in the undergraduate chemistry curriculum…
