How We Should Be Teaching Business Communication According to Findings of Writing Research
Although instructors of written business communication courses try to help students refine their writing, many instructors have had only limited-if any formal instruction in writing pedagogy. Familiarity with the pedagogy of writing will enable business communication instructors to help students improve their writing skills, especially students whose skills are substandard. When students’ writing skills are substandard, the writing process must also receive its fair share of attention. Regardless of how well students master the content and structure fundamentals of various types of business documents, the effectiveness of the material they write will be diminished when their writing skills are deficient.
Adapting Composition Theory to the Business Communication Course
Composition research provides a vast field of information from which business communication instructors can draw. Major changes in techniques for responding to student writing include teaching the process of writing and ways to teach grammar.
Effects of Equipment Dimensions on Liquid Mixing Time of Bubble Column with Draft Tube
The liquid mixing time of a bubble column with a draft tube is experimentally studied. The diameter and height of the column, the diameter and length of the draft tube, and the mode of sparging gas were changed and the liquid mixing time was measured.The lengths of bottom and top clearances have significant effects on the liquid mixing time. The liquid mixing time increases with increasing column aspect ratio of height to diameter. The liquid mixing time of the bubble column with a draft tube is longer than that of a standard bubble column when the column aspect ratio is relatively high. The liquid mixing time has a minimum when the diameter ratio of draft tube to column is 0.5 to 0.6. These effects of equipment dimensions are expressed by an equation. In the experiment using different solutions, the liquid mixing time becomes shorter with increasing liquid surface tension, or with increasing liquid viscosity.
