The purpose of this study was to investigate 4th-11th grade students' conceptual patterns with regard to "decay" in central Taiwan. The subjects included 40 students for the interview task. 275 for the open-ended questionnaires and 1266 for a two-tier multiple-choice diagnostic test; they were selected from elementary, junior and senior high schools in central Taiwan. A semi-structured interview task, open-ended questionnaires and two-tier multiple-choice diagnostic instrument were developed and conducted by a group of elementary and secondary school science teachers. Interview data and open-ended questionnaires were coded and analyzed. The two-tier multiple-choice diagnostic tests were analyzed by SPSS10.0. Results identified five conceptual patterns regarding decay: (1)natural phenomena; (2)being eaten by animals; (3)the influence of physical factors such as sunlight, air, and water; (4)assimilated decay conceptions; and (5)complete decay conceptions. Secondary students having assimilated conceptions of decay could be divided into four patterns. 4th-6th grade students tend to manifest (1)natural-phenomena and (2)devoured-by-animals conceptual patterns. 7th-11th grade students tend to manifest (4)assimilated-decay conceptual patterns.
