Students will care about how they write if you respond to WHAT they write. Comment on their insight, their main idea, their reasons, their purposes, their grasp of the subject, and their sense of how much detail or logic they needed to make their case. Students will disregard corrections of subject-verb agreement, punctuation, and so on if they have nothing to do with what they were trying to say about the subject. The syntax and grammar of language are instrumental: they enable us to construct relationships between ideas, between ideas and evidence, and between ourselves and our readers. If you comment on errors that prevent them from achieving their communication purpose and from using their scientific knowledge to create meaning, they will listen and (sometimes) remember the correction when they do their next assignment. Use your comments to help them BE the disciplinary specialist you’re inviting them to be in your class.
In each of these course types, writing assignments can serve different purposes: making connections or representing bigger problems, or comparing historical evidence, for example. Students need to know that the writing will help them achieve the purpose and strategic learning objectives of your particular course.
In the following table, imagine what the student writer might make of the comments in the columns on either side. The two outside columns show the comments of two different graders who looked at this report. This is a “B+“ lab report: not awful, but not excellent either. Some comments in each column might be useful. Mark each one that gives a good way of spotting a type of problem or a good way of fixing it. Few writers can fix what they can’t find, so both aspects are important. If you have a colleague who’s on coffee break, discuss your choices with her or with him.

| Jerky section here; doesn’t flow. Confusing, too.Why use passive voice here?This is a really slow start to your report. | Section One: This section of our report describes the design of the clock generator. It also describes the pulse generator circuits for the R327. The clock generator is a portion of the circuit that produces a square wave that is used as a system clock signal. This signal is for the whole computer. One single pulse exactly one clock cycle wide is produced by the pulse generator each time a pushbutton is pushed. It can be used for single stepping the R327 and for loading it. It can also be used for viewing its memory. | Go through and combine short sentences to eliminate unnecessary repetitions and words that the reader understands without your saying them, such as “of our report.” Watch out for pronouns here. Which “it” do you think the reader will understand? |
| You’re describing sets of things here. Try putting these in a bulleted list to make the set easier to grasp.A data block is a set of numbers; some audiences prefer the more familiar term.Don’t forget the carry-ins. | Section 2: Arithmetic Logic Unit (ALU). . . . A. The ALUThe ALU accepts two eight-bit numbers (A0-A7), B0-B7), a three-bit operation code (X0-X2) and two one-bit fields, RI and CI, used for right and left rotation and carry in, respectively. The outputs are an eight-bit number (Y0-Y7), and four one-bit fields: RO used for right rotation; C used for left rotation and carries; O used to indicate overflow; and Z used to indicate a Y=zero. | Instructor B inserts text, shown at left |
| Integrate information on two types into preceding sentenceTell a little about what these areAre you speaking of one register or multiple registers? | Section 3: Bus, Memories, and Registers This section of the R327 implements memories, registers, and the system bus. The single system bus allows for the transfer of information one byte at a time between the registers, memories, and ALU. There are two separate memories: the instruction memory (IM) and the data memory (DM). Each is reserved exclusively for its designated information type (data or instruction). The registers IN, OUT, TP, MA, IR, ACC, and PC are necessary to perform specific functions. Depending on the function, the register may need to read data off of the bus, drive the bus, or both. The bus, memories, and registers are connected as shown in Figure 18. | Duh!This sentence says nothing. |
You have years of experience writing documents of the type you’re assigning, so you know much more about how your student writers should make decisions than you think you know. You can supply guidance that people outside your field can’t give students. Try to help them internalize the rules of thumb that guide good writers in your discipline.
