Grade Level and Gender Differences in the Writing Self-Beliefs of Middle School Students.

The objectives of this study were to determine whether middle school students' writing self-efficacy beliefs make an independent contribution to the prediction of their writing competence and to explore grade level and gender differences in writing self-beliefs (N = 742). Writing self-efficacy was the only motivation construct to predict writing competence in a model that included writing self-concept, writing apprehension, perceived value of writing, self-efficacy for self-regulation, previous writing achievement, gender, and grade level. Girls were more competent writers than were boys, but there were no gender differences in writing self-efficacy beliefs. However, when students were asked whether they were better writers than their peers, girls expressed that they were better writers than were other boys or girls in their class or in their school to a greater degree than did the boys. These findings suggest that girls and boys may use a different metric when responding to traditional self-efficacy scales. Students in Grade 6 reported higher self-efficacy and found writing more valuable than did their older peers, and students in Grade 7 reported lower writing self-beliefs than did students in Grades 6 or 8.

Relation between Achievement Goals and Self-Beliefs of Middle School Students in Writing and Science.

Two studies were conducted to investigate the relationship between achievement goals (task, performance-approach, performance-avoid), motivation constructs, and gender in the areas of middle school writing (N = 497) and science (N = 281). In both studies, task goals were associated positively with self-efficacy, self-concept, and self-efficacy for self-regulation and negatively with apprehension; performance-approach goals were associated positively with self-concept; and performance-avoid goals were associated negatively with self-concept and self-efficacy for self-regulation and positively with apprehension. In writing, performance-approach goals also related positively with self-efficacy, whereas performance-avoid goals related negatively and girls had stronger task goals. Findings related to performance-approach goals suggest that a developmental component may be at work in determining whether these goals serve a facilitative function in fostering motivation. Task goals and performance-approach goals were related, suggesting that they are each grounded in self-regulatory practices that lead to positive outcomes. Copyright 2000 Academic Press.

Maternal cocaine use without evidence of fetal exposure.

We report a case of lack of fetal exposure to cocaine and benzoylecgonine as evidenced by meconium and hair analysis, but exposure to nicotine and its metabolite cotinine, after extensive maternal use of cocaine and nicotine. These data suggest that the mode of maternal use of cocaine and individual differences in placental handling of the drug may protect some fetuses, and highlight the need to address interpatient variability.
