High school biology teachers (N=18), and one 10th-grade class of each teacher, were given the Nature of Scientific Knowledge Scale at the beginning and end of a school year to determine their conceptions of the nature of science. Results (such as students not possessing "adequate" conceptions of science) are reported and discussed. (JN)

Finds no significant differences for immediate learning for students presented material orally and those presented the same material in written form. Shows, however, that students in the oral presentation mode performed significantly better than those in the reading mode on measures of delayed learning. (FL)

Results of a study on 10th-grade students to assess the effect of cognitive development stages upon writing showed that cognitive level is related to syntactic maturity across modes of composition. Research data and methodology are presented. (DF)

These papers presented at a symposium describe how tenth grade students would be taught the slope of a line in geometry using three different approaches to teaching theory: behaviorism, Piagetian cognitive development, and information processing. Analyses of each approach focus on manner of learner cooperation and differing teacher role. (MBR)

Concludes that training in a natural instructional setting can improve poor readers' ability to use top-level structure in signaled and nonsignaled passages. (FL)

The primary aims of this report are to (1) identify the incidence of daily smoking at several time points during the adolescent and young adult years, including the prevalence of new daily smokers relative to repeat daily smokers; (2) identify several specific developmental patterns of smoking; and (3) examine the specific developmental patterns…

This study examined the influence of female students' (N=90) self-monitoring and attribution on achievement when throwing darts. It was hypothesized: (1) that students who set strategic process goals and used self-evaluative recording would attribute outcomes to strategic causes; and (2) that students who set outcome goals and did not use…

This annotated bibliography identifies English language resources endorsed by all Western Canadian Protocol (WCP) jurisdictions implementing The Common Curriculum Framework for K-12 Mathematics Grade 10 to Grade 12. Resources in this annotated bibliography were selected through a collaborative review process based on their high level of fidelity…

The purpose of this study was to examine Turkish high school students' perceptions of learning environment in biology classrooms and to investigate relationships between learning environment and students' attitudes toward biology. Secondly, the study aimed to investigate the differences in students' perceptions of learning environments in biology…

A report on a study to determine the effectiveness of multimedia laboratory instruction as compared to the conventional lecture/demonstration technique when teaching the repair and servicing of carburetors to tenth-grade students. (Author)

This study investigated the effects of specific criteria for marking a test on its reliability and validity. Eight algebra word problems were administered to grade 10 students. The objectivity of scoring criteria improved the reliability of the test, but did not affect its validity. (MNS)

Three psychometric methods for validating learning hierarchies were applied to one data set derived from student responses (N=269) to items representing skills in a hypothesized hierarchy for the mole concept. The hierarchy derived from the analysis was supported by a test for transfer of learning from subordinate to superordinate skills.…
