Identifying and Meeting the Needs of Students Functioning at the Concrete Operations Stage of Cognitive Development in the General Chemistry Classroom.
Boyd, Rick B.
A cognitive gap between students' development and school curriculum may be one of the reasons why chemistry is difficult for high school students. This study examined cognitive development in the effect of modified instructional methods for students at the concrete stage of development. The Arlin Test of Formal Reasoning (ATFR) was used for measuring the students' stages of cognitive development. The ATFR results were reported by sex, course, and grade level. Fifty-four percent of the students were functioning at the formal operations stage. One unit, "Liquids and Solids," was selected and taught with diagrams and explanation sheets. Results indicated a positive impact of the modified methods. Appendices included are: (1) "Characteristics of Concrete Level Students"; (2)"Checklist for Content Anaylsis"; (3) "Explanation Sheet"; (4) "Example Problems"; (5) "Work Sheet"; and (6) "Student Evaluation Sheet of Unit/Chapter."
