Systems thinking in biology education is an up and coming research topic, as yet with contrasting feasibility claims. In biology education systems thinking can be understood as thinking backward and forward between concrete biological objects and processes and systems models representing systems theoretical characteristics. Some studies claim that…

Assessed developmental trends in competency to stand trial in a study of incarcerated and nonincarcerated adolescents (N=52) and adults (N=19). Results indicated that competency to stand trial does increase through the adolescent years, but even older adolescents received lower scores on a competency measure than did adults. (JAC)

Investigates whether the critical period for cognitive transition from concrete operations to formal operations at 12-14 years of age actually exists. Uses the Cognitive Acceleration through Science Education (CASE) intervention program in Malawi. Discusses the existence of the critical period, academic achievement, and explanations for age and…

This article reports a theoretically based study on the model of development of epistemological understanding proposed by Kuhn (2000) [Kuhn, D. (2000). Theory of mind, metacognition, and reasoning: A life-span perspective. In P. Mitchell & K. J. Riggs (Eds.), "Children's reasoning and the mind" (pp. 301-326). Hove, UK: Psychology…

Multidimensional scaling analysis was used to examine a sample of adolescents' cognitive appraisals of major and daily stressful events. The desirability of events was the only major feature for the entire sample. Older adolescents also distinguished the impact of events on their lives and generality of causes of events. (Author/JAZ)

Reports on a study that examined the relationship between age and depth of response to poetry. (HOD)

Describes the development of cognitive structure in adolescence as establishing isomorphism between subject and environment. Identifies two dimensions of stages in the development of individuals'"work structure," i.e., the network of relations existing between the individual and his work.

Students (N=178) judged the adequacy of reasons presented in stage prototypic responses to moral dilemmas to provide a profile of the frequency and strength with which students rejected early stage reasons. Data indicated definite age trends in rejecting lower-stage reasoning. Higher-stage items produced no significant age differences. (RC)

Examines seventh grade life science students, tenth grade biology students, and college zoology students for understanding of the concept of diffusion. Describes the differences among the grade levels in sound or partial understanding, misconceptions, and no understanding. Discusses the effect of developmental level on understanding. (KR)

Although many studies have described adolescents' sexual behavior and attitudes, there are little data available on the nature of the questions that occur to adolescents as they move toward maturity. A study was conducted to determine whether the questions children and adolescents ask reflect developmental differences in cognitive abilities and…

The study examined the effectiveness of two psychoeducational treatment approaches and drug therapy on the impulsivity of 120 hyperactive emotionally disturbed children in two age groups (mean ages 13 and 8 years old). The psychoeducational approaches tested were modeling of reflective behavior and a specific instructional procedure to increase…

This inquiry had two aims: to assess children's ability to interpret maps in geography; to relate the assessed ability to maturity of thought as proposed by Peel, general intelligence, and age. It was found that performance on four tests depended more on intelligence than on maturity of thought or age. (Author/SJL)

Preferences for asymmetry in the relationship between metaphorical topic and vehicle were investigated among 64 fifth- and seventh-grade boys and girls. Subjects viewed 12 metaphorically related pairs of pictures selected from the Metaphoric Triads Task (MTT) and were told to write a sentence that tells how one picture is like another. Slides of…

Literature on cognition and learning in young adults is surveyed. First, an outline of a theory of the cognition-learning system is presented, reviewing the characteristics of each of the major components of the system. Particular attention is paid to the differences between young adults and other age groups in information processing skills.…

Investigates differences between adolescents and older adults in their explanations of linguistic metaphors. Adults displayed a synthesizing, integrative perspective, while adolescents displayed an analytic perspective in their explanation of metaphors. (Author/SS)
