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)

Assesses the ability of tenth grade students (n=364) to acquire meanings of graphs that are frequently used in their biology textbooks. Indicates that the main source of failure to process information equally well from tables and graphs was not a lack of basic analytical skills but rather a lack of understanding of the relationship between…

Students (n=46) were assigned to one of three instructional groups (descriptive, question design, and hypothesis testing) to test the hypothesis that descriptive learning cycles are not sufficient to stimulate students to reason at a formal operational level. Analyses indicated that the hypothesis-testing group exhibited a significant increase on…

Reviews the theoretical framework of instructional programs and the emphasis on enhancing formal reasoning ability. Investigates the effect of an instructional program using inquiry-based learning in pre-service science teacher education students. Reports that the promotion of formal reasoning abilities may be achieved through the five-phase…

Reviews research related to teaching and learning higher cognitive level objectives from a constructivist perspective. Examines several factors including the cognitive demands of academic work, classroom management, delivery of instruction, formal reasoning ability, grouping of students, and motivation to learn. Concludes that an active teaching…

Contends that student success in introductory science courses at the college and university level depends on formal operational reasoning ability, size of working memory, and the degree of field independence. Reports the study findings related to cognitive predictor variables based on the testing of Venezuelan science majors (N=95). (ML)

Discusses a study that examined which reasoning patterns are necessary for success in high school chemistry. Based on student (N=170) scores from the "Classroom Test of Formal Reasoning," it was revealed that students who use formal reasoning patterns are capable of greater achievement in chemistry. (ML)

Discusses a study which compared differences in ratio construction made by high school freshman and junior students. Reports that more freshmen than juniors selected solutions involving one variable, whereas juniors chose solutions that coordinated two variables in a mathematical or verbal rule. Reviews implications in problem solving and concept…

Analyzed is the role of formal logic in the development and investigation of science education. Investigated are the use of logical relations in the learning of abstract concepts and the development of efficient cognitive processes in the context of science curricula. (Author/YP)

Investigated were the relation between functional M-capacity and student performance in solving chemistry problems of increasing M-demand. Student performance decreased as the M-demand of the problems increased. (Author/YP)

Reviews the neural modeling principles of learning, perception, cognition, and motor control, discusses their applications to sensory-motor problem solving, and explores possible relationships between that pattern of problem solving and aspects of higher order formal operational problem solving. Cites implications for science education. (ML)

While logical reasoning skills are related to success in science, the relationship between thought and formal logic is not clear. Propositional Logic Test (PLT), error patterns of students' interpretations of logical proposition, and developmental patterns of the error type are described. Examined is the relationship between logical reasoning…

Explains the convergent and discriminant validity of two tests of science process skills with two tests of formal reasoning ability. Reports test results from elementary education majors and discusses the tests' intercorrelations. Implications related to instruction are analyzed. (ML)

Presents study findings which explored the effect of teacher reasoning level and teaching style preference on improvement in student-reasoning ability. Reports that students of concrete operational teachers and of inquiry teachers showed greater gains in reasoning ability than students of formal operational teachers and of expository teachers. (ML)

Physical and Earth Science AB, a required senior high school course in the Los Angeles Unified School District, uses an investigative approach for developing scientific understanding and attitudes for students. Contents include: (1) summary of representative objectives; (2) teacher responsibilities; (3) the agenda; (4) guidelines for assignment of…
