The instruction on writing papers at college is done to improve students’ competence in expressing ideas and attitudes toward knowledge through scientific papers. This competence, referring to Bloom’s taxonomy, involves cognitive, psychomotor, and affective domain. Cognitive domain is developed by Anderson-Krathwohl, Gagne, Ausubel, Merrill, Reigeluth, and Biggs-Collis.Psychomotor domain is developed by Dave, Simpson, Harrow, Bixler, Romiszowski and Dyers.Affective domain is developed by Krathwohl, Bloom, and Masia. These three domains set the foundation of instructional goals to achieve in instruction on writing papers. The present paper is aimed to describe cognitive, psychomotor, and affective domains in instruction focusing on writing papers. The results constitute the description of (a) cognitive domain: formulating the aspects of language (spelling, words, sentences, paragraphs), systematics, technical, and paper-writing format, (b) psychomotor domain: being skilled in writing the opening part, the content, and the closing part of paper, (c) affective domain: to have the attitude of being honest, respectfulto others, responsible, obedient to rules, and disciplined.
