An Inventory of Piaget's Developmental Tasks was used to assess attainment of five Piagetian tasks of elementary and secondary-level teacher candidates and of general population college students. Results were compared and are discussed. Recommendations to promote cognitive maturity are presented. (Author/MT)

Extends prior theory and research by postulating the existence of an intermediate class of concepts called 'hypothetical'. Investigates the hypothesis that three kinds of scientific concepts exist by constructing and administering a test on concepts introduced in a college biology course. Supports the hypothesis that intellectual development…

College students were assigned to either dyadic or individual problem-solving conditions and were given a series of formal operational tasks. Dyadic subjects solved more problems during the interaction phase than did individual subjects. Among dyadic subjects, interactions were associated with problem solving and pre-to-posttest gain scores. (BC)

Research involving cognitive modification and using intervention instruction in general prerequisite cognitive processes has shown that significant and long-term results are possible. Use of intervention instruction involving prerequisite data gathering skills with teachers has been successful in improving ability to use probing questions in…

This study investigated the formal reasoning ability and the relationship between reasoning ability, sex, and age of 600 preservice primary teachers in Nigeria. Findings are summarized. (MT)

Investigated was the relation between student ability to translate sentences into equations, equations into sentences, and student performance in formal operational reasoning, proportional reasoning, and introductory-level chemistry. Results indicate that students who lack formal operational skills may experience problems in the translation of…

Reports a study of 922 college students that classified the students based on performance on formal operational reasoning tasks. Students were also administered seven logic tasks. Response patterns were analyzed and found to be similar to patterns derived from the multiple-hypothesis theory of advanced scientific reasoning and different from those…

Presented is a study in which students' intellectual reasoning development was evaluated following instruction that emphasized formal operations in a traditional lecture format. Results indicated that formal-operational students had significantly more success in the three reasoning areas than transitional students and transitional students had…

Seventeen college undergraduates, possessing either basic or consolidated formal operations, received eight weeks of interpersonal skills training and pre- and posttraining assessments of social perspective taking and moral reasoning. Gains in moral reasoning were related to subjects' possessing prerequisite cognitive and perspective-taking…

Assessed was the level of thinking of 140 students who had been placed in developmental algebra as entering college freshmen. Scores on the Group Assessment of Logical Thinking, Scholastic Aptitude Tests, college placement tests; high school grade point average, and developmental algebra final grade were analyzed. Group characteristics are…

Examines the relationship between adolescent egocentrism and postformal thinking in 163 college undergraduates. Uses the Imaginary Audience Scale and the Social Paradigm Belief Inventory to evaluate participants. Results indicate that females have higher levels of adolescent egocentrism than do males. (Author/GCP)

Previous investigations on Piagetian cognitive levels among college students both within and across academic disciplines have not addressed the issue of possible differences in cognitive levels between traditional undergraduates and older returning students. Piagetian cognitive levels were studied among traditional- and nontraditional-age college…

Investigated is the ability of high school pupils and university students to answer questions based on relationships within food webs using sound ecological principles. Research methods used and the results of this study are discussed. (CW)

Discusses two strategies that provide concrete-thinking students with opportunities to develop and use formal or critical-thinking skills. Describes using task analysis and long-term investigations in the classroom. (YP)

Misconceptions, shown to be prevalent in students even at the college level, may affect the cognitive process of making predictions in biology. The purpose of this study was to: (1) identify students' misconceptions about important biological concepts; (2) identify students' cognitive behaviors associated with making predictions about these…
