Davis, Richard A. – Chemical Engineering Education, 2020
A case study of regression analysis based on modeling Gilliland's correlation was described for use in a computational methods course. The case study uses a familiar example to train students in nonlinear least squares regression and to use standardized residual plots for model assessment. Previously published equations for Gilliland's correlation…

Shang, Hao – Journal of Chemical Education, 2021
Here, we present an interdisciplinary educational project intended for high school chemistry that is focused on the establishment of a mathematical model to describe the relationship between conductivity and concentration, while linking chemistry to mathematics with the help of computer software. The project was designed to help high school…

Sidou, Lais Feltrin; Borges, Endler Marcel – Journal of Chemical Education, 2020
Principal component analysis (PCA) is one of the most important and powerful methods in chemometrics as well as in a wealth of other areas. Running a PCA results in two main elements, the score plot and the loading plot; the score plot provides the location of the samples, and the loading plot indicates correlations among variables, the trends in…

Xu, Binyan, Ed.; Zhu, Yan, Ed.; Lu, Xiaoli, Ed. – Research in Mathematics Education, 2021
This book seeks to illustrate the research on mathematics competencies and disposition in China according to the conceptual development and empirical investigation perspective. Mathematics education in China has a distinguishing feature a focus of attention to mathematical competency. Paradoxically, there has not been an explicit, refined, and…

Weinburgh, Molly; Silva, Cecilia; Smith, Kathy Horak – NSTA Press, 2019
Many middle and high school teachers are educated to teach science content--they don't anticipate that one day they may be teaching it to students who need to learn both content and English. If the day has come when you're facing that two-pronged challenge, here's the resource you need. "Supporting Emergent Multilingual Learners in…

Chernyavskaya, Yana S.; Kiselev, Sergey V.; Rassolov, Ilya M.; Kurushin, Viktor V.; Chernikova, Lyudmila I.; Faizova, Guzel R. – International Journal of Environmental and Science Education, 2016
The relevance of research: The relevance of the problem studied is caused by the acceleration of transition of the Russian economy on an innovative way of development, which depends on the vector of innovative sphere of services and, to a large extent, information and communication services, as well as it is caused by the poor drafting of…

de la Vega-Herna´ndez, Karen; Antuch, Manuel – Journal of Chemical Education, 2015
A vectorial representation of the full sequence of events occurring during the 2D-NMR heteronuclear single-quantum correlation (HSQC) experiment is presented. The proposed vectorial representation conveys an understanding of the magnetization evolution during the HSQC pulse sequence for those who have little or no quantum mechanical background.…

Hitt, Austin Manning; Townsend, J. Scott – Science Activities: Classroom Projects and Curriculum Ideas, 2015
Elementary, middle-level, and high school science teachers commonly find their students have misconceptions about heat and temperature. Unfortunately, student misconceptions are difficult to modify or change and can prevent students from learning the accurate scientific explanation. In order to improve our students' understanding of heat and…

Huber, Daniel; Jones, Leslie; Helminski, Christine – Australian Mathematics Teacher, 2015
The use of collaborative problem solving within mathematics education is imperative in this day and age of integrative science. The formation of interdisciplinary teams of mathematicians and scientists to investigate crucial problems is on the rise, as greater insight can be gained from an interdisciplinary perspective. Mathematical modelling, in…

Freund, Philipp Alexander; Kasten, Nadine – Psychological Bulletin, 2012
Individuals' perceptions of their own level of cognitive ability are expressed through self-estimates. They play an important role in a person's self-concept because they facilitate an understanding of how one's own abilities relate to those of others. People evaluate their own and other persons' abilities all the time, but self-estimates are also…

Rutherford, Gayle E.; Walsh, Christine A.; Rook, John – Journal of Teaching in Social Work, 2011
To tackle the complexity of issues associated with homelessness, an interdisciplinary lens with direct input from service providers and community members is necessary. Within a community-university partnership between a larger inner-city multiservice shelter serving the homeless population, and faculties of social work and nursing in a Canadian…

Marks, Melanie; Kotula, Gemma – Social Studies, 2009
The circular flow of income diagram is a traditional starting point for economics taught at the high school and college level. Although it is an incredibly useful tool for illustrating how money flows through the economy, the model can be abstract and relies on a sophisticated vocabulary that makes it impractical for use with younger students.…

Skaalvik, Einar M.; Skaalvik, Sidsel – Teaching and Teacher Education: An International Journal of Research and Studies, 2010
The purpose of this study was partly to test the factor structure of a recently developed Norwegian scale for measuring teacher self-efficacy and partly to explore relations between teachers' perception of the school context, teacher self-efficacy, collective teacher efficacy, teacher burnout, teacher job satisfaction, and teachers' beliefs that…

Elmslie, Bruce T.; Tebaldi, Edinaldo – Journal of Economic Education, 2010
Many instructors in subjects such as economics are frequently concerned with how to teach technical material to undergraduate students with limited mathematical backgrounds. One method that has proven successful for the authors is to connect theoretically sophisticated material with actual data. This enables students to see how the theory relates…
