Q. I need help finding articles on electronic assessment.

A good source for the education literature is Education Index. EI uses the term "grading and marking" to describe assessment -

"Here are entered works concerned solely with evaluation of academic achievement. Works concerned with testing student academic achievement and aptitudes are entered under "Educational tests & measurements." Works on evaluating students on their total performance, including academic achievement, behavior, attitudes, interest, motivation, participation, etc., are entered under "Students -- Rating of." Works on the placement of students into a particular grade are entered under "School grade placement." [EPC]"

To be safe, I added the keyword "assessment." I then combined it with the keyword "electronic."

((DE grading and marking) OR (assessment)) AND electronic

I limited the result list to academic journals.

You can browse the results here -
