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…

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…

Presents a comparative analysis of the psychometric properties of three group tests of logical thinking used in science education research. Findings dealing with Longeot's Test of Logical Thinking, Lawson's Test of Formal Reasoning, and Tobin and Capie's Test of Logical Thinking demonstrate a lack of concurrent validity. Includes recommendations.…

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)

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…

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…

Reviews recent research addressing the problem of matching students' cognitive levels to science textbooks. Suggests that most texts are written above the level of the students for whom they are written. Promotes experiential learning at the middle level and concentration on "right thinking" rather than on "right answers." (CW)

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)

Attempts to show that not only can density be taught to lower ability pupils but that by doing so, there is the possibility of assisting pupils to develop their reasoning powers. Lists teaching activities that help in this process. (CW)

The reasoning abilities to be expected of the concrete operational and formal operational student, the percentage of secondary science students that are capable of each type of reasoning pattern, and effective strategies to teach science to concrete reasoners are described. Implications for curriculum development are discussed. (KR)
