The purposes of this study were to (1) study changes in attitude toward science, school, and academic self among college biology students, and (2) to examine relationships between attitudes and achievement in an introductory college course in biology. The three attitude variables were assessed at the beginning and end of the study. Each of the three constructs was measured by the semantic differential and one additional instrument. One cognitive measure, biology achievement, was taken at the beginning and end of the study. This was accomplished by using the Nelson Biology Test. Another cognitive measure, grade in the course, as given by the instructor, was recorded at the end of the course. Normative data and correlation coefficients among pre- and postadministrations were calculated for each institution and the composite sample as well. An analysis of variance showed that while gains in scores on the Nelson Biology Test were significant beyond the 0.01 level of probability, changes in attitude scores were not. Correlations were calculated between the attitude and cognitive variables in this study. Relationships between academic self-concept and achievement in biology were the strongest. Data from this study show that while student cognitive behavior was changed during an introductory college biology course, selected attitudes either stayed the same or became slightly more negative. Affective as well as cognitive gains would appear to be desirable goals in college courses. As we learn more about relationships that exist between cognition and affect, science educators at all levels will become better equipped to improve learning in science. 相似文献

Childbirth educators can have a significant impact on safe care for mothers and babies during the second stage of labor. In this guest editorial, educators are encouraged to make sure they are knowledgeable about the latest evidence for best second-stage-care practices so they can adequately prepare women to advocate for themselves during this time. 相似文献

This study investigated the influence of external load training (ELT) on static and dynamic balance. Nineteen females stratified into two groups (ELT = 9, control = 10) completed three testing sessions over 6 weeks. The ELT group wore weighted vests (WV) of ~8% body mass for 32 h/week during daily living and three training sessions/week for 3 weeks. Following completion of ELT, a 3 week detraining (DET) phase was completed. Bilateral and unilateral static balance were assessed with eyes open and closed. Dynamic balance was assessed using the star excursion balance test (SEBT). Static and dynamic balance variables were analysed using a 2 (group) x 3 (time) between participants repeated measures ANOVA (p < 0.05). Results revealed significant reductions in average centre of pressure (COP) velocity in the control group on the non-dominant limb with eyes closed, and significantly greater reach distances in the ELT group on the SEBT for the posteromedial and medial directions on the dominant limb (p < 0.05). These findings suggest the ELT group did not significantly improve their balance in comparison to the control group. However, future research should further examine this unique, supplemental training method and the impact on balance performance. 相似文献
