Introductory materials science and engineering courses universally include the study of crystal structure and unit cells, which are by their nature highly visual 3D concepts. Traditionally, such topics are explored with 2D drawings or perhaps a limited set of difficult-to-construct 3D models. The rise of 3D printing, coupled with the wealth of…

A semester-long group project that utilizes wiki sites to enhance collaboration was developed for a foundation course in inorganic chemistry. Through structured assignments, student groups use metal-based or metal-combating therapeutic agents as a model for applying and understanding course concepts; they also gain proficiency with scientific- and…

In this study, a computational molecular orbital theory experiment was implemented in a first-semester honors general chemistry course. Students used the GAMESS (General Atomic and Molecular Electronic Structure System) quantum mechanical software (as implemented in ChemBio3D) to optimize the geometry for various small molecules. Extended Huckel…

Jmol is free, open source software for interactive molecular visualization. Since it is written in the Java[TM] programming language, it is compatible with all major operating systems and, in the applet form, with most modern web browsers. This article summarizes Jmol development and features that make it a valid and promising replacement for…

It is suggested that molecular theory should be taught earlier in the inorganic chemistry curriculum even in the introductory chemistry course in order to integrate molecular orbital arguments more effectively throughout the curriculum. The method of teaching relies on having access to molecular modeling software as having access to such software…

Describes the development of a chemistry lecture course called CHEMnet that is available via the internet and optimizes multimedia learning environments. Investigates the use and efficiency of multimedia teaching and learning software with CHEMnet. Discusses the structure and features of CHEMnet along with numbers and characteristics of its use.…

Describes two computer programs used to aid in data analysis: (1) Develops a method for the propagation of error involving the direct calculation of the error in the dependent variable using a spreadsheet; (2) Examines a simple numerical method for solving complex equilibria. Lists a FORTRAN 77 program. (MVL)

States that quantitative modelling allows teachers to concentrate more on qualitative understanding. Suggests the main benefits as (1) repetitive calculations are reduced allowing greater attention to be focused on underlying models; (2) more "what if" models can be tested; and (3) a wider variety of data can be used to test models. (MVL)

Describes a possible exam or homework problem for a physical chemistry course. Investigates the temperature and concentration dependence of homogeneous chemical equilibria. Provides acceptable solutions. Offers a computer program able to provide partial credit on questions requiring four-seven sequenced items. Program available from author. (MVL)

Provides an eclectic annotated bibliography of secondary sources for inorganic reactivity information of interest to reactivity network review authors and to anyone seeking information about simple inorganic reactions in order to develop experiments and demonstrations. Gives 119 sources. (MVL)

Reported are the results of computer software used in eight different situations. Topics considered include scheduling, test generation, data checking, databases, temperature probes, automated samplers, wireless data communications, and the "group three" phenomenon. (CW)

Contains ratings of two software packages for Apple II computers: "Acid-Base Titrations, CHM311A" and "Chemical Principles for the Introductory Laboratory, CHM 384A." Both are aimed at high school and college chemistry and are rated on ease of use, subject matter content, pedagogic value, and student reaction. (CW)

Notes two uses of computer spreadsheets in the chemistry classroom. Discusses the general use of the spreadsheet to easily provide changing parameters of equations and then replotting the results on the screen. Presents a molecular orbital spreadsheet calculation of the LCAO-MO approach. Supplies representative printouts and graphs. (MVL)

Describes the use of computer spreadsheet programs in physical chemistry classrooms. Stresses the application of bar graphs to fundamental quantum and statistical mechanics. Lists the advantages of the use of spreadsheets and gives examples of possible uses. (ML)
