The Impact of Virtual Office Hours on In-Class Participation
This study investigated whether there would be an increase in college student's participation in a college methods course that utilized virtual office hours. Virtual office hours involved a specific time when the professor was available for private or public questions and discussions via the Internet. Two groups of students participated in a social studies methods course where virtual office hours were made available twice a week. Laptop computers were issued fo'r the duration of the semester. Students also participated in required asynchronous discussions online. Data were collected from the course and from student interviews regarding the virtual experience. Results indicated that participating students developed a classroom culture that functioned during the virtual office which not only supported classroom discussions but also created a comfort level that augmented participation during the actual class time. Students reported that the virtual office hours had a direct impact upon class discussions. The virtual office provided students with a model of thoughtful discussions that they could then practice for themselves. With the confidence developed from this practice, students subsequently developed their own means of putting these ideas into practice. (Contains 22 references.)

Education for an information age : teaching in the computerized classroom
This text looks at the use of computers in the classroom. It is designed to help present and student teachers become computer literate and to integrate the computer into the classroom. The philosophical, historical and social context for understanding the role computers play in education is discussed. Case studies relate the material to everyday life and a Microsoft Works Tutorial is also included.
Thermodynamics on the Carbochlorination of Titanium-bearing Ores
The equilibrium compositions of the multi-component, multi-phase and multi-reaction system of carbochlorination of titanium-bearing ores are calculated with HSC, a computational chemistry software. The thermodynamic equilibrium calculation of the reaction system shows that a complete conversion of titanium-bearing ores is feasible at a temperature near 200oC. At temperatures ranging from 800 to 1600oC, the products of the reaction system are all in gaseous phase. Thermodynamic analysis accords with the industrial practice. The simulated results provide reasonable scientific basis for improving suitable technological conditions of the carbochlorination reduction.
