Recent reform efforts have been adopted in the United States to reimagine student learning in science. Historical reform efforts have required teacher buy-in necessary for substantive change to occur. Using a mixed-method methodology, chemistry teacher progress in implementing the "Next Generation Science Standards" in Illinois and views…

Mechanistic reasoning, or reasoning systematically through underlying factors and relationships that give rise to phenomena, is a powerful thinking strategy that allows one to explain and make predictions about phenomena. This article synthesizes and builds on existing frameworks to identify essential characteristics of students' mechanistic…

The purpose of this laboratory experiment is to study fundamental concepts of kinetics and equilibria and the isotope effects associated with both of these concepts. The concepts of isotopes in introductory and general chemistry courses are typically used within the contexts of atomic weights and radioactivity. Kinetic and equilibrium isotope…

We implemented a laboratory curriculum reform to teach foundational concepts in chemistry, particularly those concepts related to healthcare, in a chemistry course for prenursing students. Here, we discuss the reform, exploring how students built upon understandings gained in lab and correlating lab learning to course outcomes. We further discuss…

Isothermal titration calorimetry was used to experimentally determine thermodynamic values for the ethylenediaminetetraacetic acid (EDTA)(aq) + M[superscript 2+](aq) reactions (M[superscript 2+] = Ca[superscript 2+] and Mg[superscript 2+]). Students showed that for reactions in a N-(2-hydroxyethyl)piperazine-N"-ethanesulfonic acid (HEPES)…

Recruitment and retention in the sciences is both difficult and crucial, especially in the community college setting. In this study, the resources used by General Chemistry I students at two different public, predominantly two-year colleges in two states were studied via surveys for a semester. Data were analyzed with respect to student attitudes…

The hands-on laboratory experiments are frequently what spark students' interest in science. Students who are blind or have low vision (BLV) typically do not get the same experience while participating in hands-on activities due to accessibility. Over the course of approximately nine months, common chemistry laboratory experiments were adapted and…

Many students probably know something about space from playing computer games or watching movies and TV shows. Teachers can expose them to the real thing by launching their experiments into near space on a weather balloon. This article describes how to use high-altitude ballooning (HAB) as a culminating project to a chemistry unit on experimental…

An environmental chemistry service-learning project was implemented by Greenville University in coordination with the local county health department to test the quality of well water for residents in a five-county region of southern Illinois. Well owners attended a student run well water testing "kickoff meeting", received testing kits,…

Collaborative learning involves an interdependence between success of the individual and success of the group, requiring both personal preparation and teamwork. Asynchronous work, in combination with group interaction and problem solving, differentiates collaborative learning from other interactive teaching methods. In this study, three professors…

The Center for Authentic Science Practice in Education (CASPiE) is a National Science Foundation funded initiative that seeks to introduce first- and second-year undergraduate students to research in their mainstream laboratory courses. To investigate the effects of this research-based curriculum, a longitudinal study was initiated at Purdue…

This article describes the specific methods of a regional partnership that has lasted more than twenty-five years. Southern Illinois University Edwardsville has partnered with public and private schools in the southwestern portion of Illinois, and in metro St. Louis, in the Hands-On Science project, which provides instruction development for…

The author created and has been teaching a first-year seminar (FYS) called "Food for Thought: Rhetoric of the Edible" for the past three years. Sustainability and ethics in the production and consumption of food have been tangential topics that have arisen in the course. While her academic background is composition and rhetoric, food has…

The classroom exercise outlined here is a self-directed assignment that connects students to the environmental contamination problem surrounding the DePue Superfund site. By connecting chemistry knowledge gained in the classroom with a real-world problem, students are encouraged to personally connect with the problem while simultaneously…

When the Illinois Mathematics and Science Academy (IMSA) was founded in 1985, the state of Illinois charged IMSA with two mandates: (1) "The primary role of the Academy shall be to offer a uniquely challenging education for students talented in the areas of mathematics and science." (2) "The Academy shall also carry a responsibility…
