To promote student involvement in the reduction of chemical waste generated by teaching laboratories, a method published by Flinn Scientific for the treatment of waste sodium molybdate has been modified for use in treating waste generated by the popular molybdenum blue method for the analysis of phosphate in natural water samples. In this teaching…

To present the difference in oxidizing strength in concentrated and dilute nitric acid reacting with copper, a simple, facile demonstration of these reactions is designed using a waste plastic bottle, plastic droppers, and syringes, which are costless and easily assembled. This new version can be used to demonstrate the difference in oxidizing…

We present the design of a periscope-type VIS spectrometer for educational purposes that combines strong features from various earlier designs and adds new ones. Three 3D-printed pieces that hold a small thin mirror sheet, a 1/8th wedge of a DVD, and two razor blades are easily assembled and facilitate insight into its construction. A new feature…

Confirmative evaluation is often noted as an important element of models of Human Performance Technology and Performance Improvement, but there exists confusion around what is and what is not confirmative evaluation. A significant issue limiting the use of confirmative evaluation is the Performance Improvement field's inability to clearly classify…

Different teaching and learning strategies have informed physics educators on addressing the cultural meanings and practices of physics that have sustained homogeneity within university programs. However, literature evidence physics learning environments are under-theorized in dismantling homogeneity and conceptually changes physics student…

The purpose of this study is to present the fundamental principles, methods, and effective communication methods of oral discipleship training for the believers in the oral cultures. To achieve the purpose, the researcher analyzed the data obtained from the individual interviews with 25 manaschys and 30 Kyrgyz Christian ministers. In this…

In response to the federal Race to the Top grant initiative that aimed to increase teacher accountability, the state of Tennessee created the Tennessee Student Growth Portfolio Model (TSGPM) to evaluate its non-tested teachers. This optional alternate evaluation model for non-tested teachers was developed and piloted by fine arts educators in the…

Latina preservice science teachers make the transition from science student to teacher is scant. This study aims to address this gap by exploring improvisation as a pedagogical tool in order for Latina pre-service teachers make meaning of the transition from student to teacher and what this might mean in terms of identity. According to Pool et al.…

The link between vocabulary knowledge acquisition and its effect on reading comprehension has been well established over years of research; however, students from low income backgrounds may have less access to the opportunities that allow for the building of this vocabulary knowledge prior to and including entry into formal schooling. Therefore,…

Nursing has a history of pursuing interventions aimed at improving health equity and reducing health disparities. In recent years, social determinants of health (SDOH) have demonstrated to be key factors in the pursuit of these aspects. The connection of these social determinants to health outcomes has reinforced the need for healthcare…

Molecular modeling can be used as an excellent teaching method for providing better insight into the mechanism of free radical reactions. Due to its highly visual nature, it can affect and improve students' perception and visualization of chemistry phenomena. The majority of chemistry students will know how to represent a reaction between two free…

Many Philosophy for Children (P4C) practitioners in different parts of the world have recognized the need for contextually relevant texts and created new stories and other materials to use as starting points for inquiry, some more sophisticated and comprehensive than others. P4C (Philosophy for Children) stands for the name of the comprehensive…

Contemporary scholars, educators, and practitioners continue to engage in robust debates about how to research and practice philosophy with children and adolescents and how to theorize its foundational concepts. With a view to promoting such scholarly argumentation, this essay considers issues addressed by Wendy Turgeon and Thomas E. Wartenberg in…

Multidimensional Item Response Theory (MIRT) is widely used in educational and psychological assessment and evaluation. With the increasing size of modern assessment data, many existing estimation methods become computationally demanding and hence they are not scalable to big data, especially for the multidimensional three-parameter and…

This essay advances the argument that the fields of nature conservation and music sustainability are unified by shared concerns. Namely, commodification and "economic development engender approaches to the exploitation of culture that are often identical to the strategies for corporate profiteering of natural resources. Philosophical views of…
