Primary school teachers need adequate professional knowledge and motivational orientations to qualify scientifically and technologically literate students. Previous studies have focused on the impact of coursework on (pre-service) primary teachers' content knowledge, rather than on the development of academic self-concepts. In addition, the…

Developing scientific reasoning (SR) is a central goal of science-teacher education worldwide. On a fine-grained level, SR competency can be subdivided into at least six skills: "formulating research questions," "generating hypotheses," "planning experiments," "observing and measuring," "preparing data…

An interactive poster exhibited at two poster sessions at the Fall 2016 American Chemical Society (ACS) National Meeting was used as a vehicle to learn about ACS members' concerns and needs related to research ethics and to identify opportunities for engagement of the Society by the Committee on Ethics (ETHX) and others in terms of ethics…

This study explores the acid-base topic in the context of a chemistry course taken as a prerequisite for a baccalaureate nursing program. Core findings were derived from semistructured interviews with experts in the areas of chemistry and nursing, and a multiple university survey of experts' opinions. The acid-base topic was reviewed and evaluated…

The scale-invariant way to analyze two-dimensional experimental and theoretical data with statistical errors in both the independent and dependent variables is revisited by using what we call the triangular linear regression method. This is compared to the standard least-squares fit approach by applying it to typical simple sets of example data…

In this study, 52 students in Padang, West Sumatra, Indonesia used an e-learning system to study a chemistry topic. Students' e-learning activities were recorded, and their perceptions and expectations regarding e-learning were determined via an open-ended questionnaire after the study. There were more students who perceived e-learning as a…

Despite the importance of asymmetric catalysis in both the pharmaceutical and commodity chemicals industries, asymmetric catalysis is under-represented in undergraduate chemistry laboratory curricula. A novel guided-inquiry experiment based on the asymmetric aldol addition was developed. Students conduct lab work to compare the effectiveness of…

Bioinorganic topics are ubiquitous in the inorganic chemistry curriculum; however, experiments to enhance understanding of related topics are scarce. In this proposed laboratory, upper undergraduate students assess the biological interaction of molybdenocene dichloride (Cp2MoCl2) with bovine serum albumin (BSA) by fluorescence spectroscopy.…

This research was focused on investigating the effect of multiple intelligence-based learning as a learning approach towards students' concept mastery and interest in learning matter. The one-group pretest-posttest design was used in this research towards a sample which was according to the suitable situation of the research sample, n = 13…

This guided-inquiry, upper-division undergraduate organic lab experiment, a hybrid of problem-based learning (PBL); process-oriented, guided-inquiry learning (POGIL); and peer-led team learning (PLTL) has been developed to ease the transition from the undergraduate lab to a research lab environment. The characterization of a mixture of camphor and…

This study explores the outcomes of a chemistry MOOC, delivered on two occasions through the FutureLearn platform. Learner background and course feedback, including managing the expectations of potential participants, course facilitation, the importance of having a strong presence on the forums and the tutor having a 'face', is explored. The…

Despite gains in baccalaureate and master's degree attainment, women continue to earn lower shares of doctor of philosophy degrees (PhDs) in many fields, a pattern that is often pronounced in science, technology, engineering, and math (STEM). This article uses comparative case study to understand organizational trajectories toward gender parity…

Ellen Swallow Richards is traditionally cited as the founder of family and consumer sciences (FCS). A chemist, she drew from her root discipline, applying its concepts to the needs of the family and the individual. Much of what she advocated was based on the work of mid-19th century German chemists, particularly Justus von Liebig. Before Richards…

This study explores how graduate students learn to participate in collaborative international science research. As part of an NSF-funded program, 21 graduate students participated in extended research visits to China, completing surveys before and after traveling, and participating in semistructured interviews upon returning to the U.S. These…

An integrated laboratory experiment applying concepts and techniques from organic chemistry, inorganic chemistry, and instrumental analysis is presented for use in the undergraduate curriculum. This experiment highlights the synthesis, characterization, and use of tris(2-pyridylmethyl)amine (TPMA) to make complexes with different metal salts. It…
