Project-based learning (PJBL) is student-centered and teamwork educational activity that prepares students for the challenge of real-world problems. This kind of instructional method is highly recommended by the Accreditation Board for Engineering and Technology (ABET).This paper describes an authentic project that focuses on the preparation of…

We developed a comprehensive training module for the undergraduates majoring in chemical education with a simple microfluidic experiment. The students were required to read a scientific reference offered by the instructor, then design and implement a microfluidic experiment for real sample analysis by making some modifications to the method…

An understanding of protein folding relies on a solid foundation of a number of critical chemical concepts, such as molecular structure, intra-/intermolecular interactions, and relating structure to function. Recent reports show that students struggle on all levels to achieve these understandings and use them in meaningful ways. Further, several…

We describe the construction and initial demonstration of a new instructional tool called ROXI (Research Opportunity through eXperimental Instruction). The system interfaces a series of electronic sensors to control software via the Arduino platform. The sensors have been designed to enable low-cost data collection in laboratory courses. Data are…

A rapid separation of three photosynthetic pigments (chlorophyll "a" and "b" and xanthophyll) from fern ("Polystichum acrostichoides") is described using microscale solvent extraction and traditional thin layer chromatography that minimizes use of harmful chemicals and lengthy procedures. The experiment introduces…

Laboratory-based courses require students to compose reports based on the performed experiments to assess their overall understanding of the presented material; unfortunately, the sterile and formulated nature of the laboratory report disinterests most students. As a result, the outcome is a lower-quality product that does not reveal full…

The technique, termed "collaborative critiquing", was developed to teach fundamental technical writing skills to analytical chemistry students for the preparation of laboratory reports. This exercise, which can be completed prior to peer-review activities, is novel, highly interactive, and allows students to take responsibility for their…

This article describes the use of a progressive paper in a capstone course to develop students' writing skills. A progressive paper is one that students write one section at a time: as they add each new section, they go back and revise the previous parts based on actionable feedback from the instructor. In this course, the progressive paper takes…

The central goal of this exploratory study was to characterize the effects of experiments involving different levels of inquiry on the nature of college students' written reflections about laboratory work. Data were collected in the form of individual lab reports written using a science writing heuristic template by a subset of the students…

A series of qualitative analysis (QA) laboratory experiments utilizing a problem-based learning (PBL) module has been designed and implemented. The module guided students through the experiments under the guise of cleaning up a potentially contaminated water site as employees of an environmental chemistry laboratory. The main goal was the…

A small group of high school students performed a virtual laboratory experiment in Second Life that mimicked a real experiment in both its appearance and procedure. Lab report grades were equivalent to report grades for hands-on experiments, and the quality of students' results was similar. Results of an attitudinal survey show that students…

This paper presents a formulation of the second law of thermodynamics couched in terms of Shannon's measure of information. This formulation has an advantage over other formulations of the second law. First, it shows explicitly what is the thing that changes in a spontaneous process in an isolated system, which is traditionally referred to as the…

The nature of laboratory work has changed in the past decade. One example is a shift from working individually or in pairs on single traditional verification experiments to working collaboratively in larger groups in inquiry and research-based laboratories, over extended periods in and outside of the lab. In this increased era of collaboration, we…

The following topics were discussed: Objectives of Education in Chemistry; Beyond the Conventional Classroom; New Directions for the Traditional Classroom; Relevance and Significance YConcerning Instruction ObjectivesI; and Environmental Chemistry and Chemistry for Chemical Technicians, Citizens, and Poets. (DF)

Summarizes the discussions held in the Eighth Biennial Education Conference of the American Chemical Society, including recommendations on manpower development, stimulation of job market, career guidance and education, new directions for educational institutions, improvement of educational programs, control of educational quality, and…
