Engaging Quiet Students in the College Classroom

Quiet students are sometimes misunderstood in the college classroom. Students may be quiet for reasons related to personality traits, learned behaviors, or situational factors, but regardless, their silences may be misinterpreted by their instructors as a lack of engagement in their courses. In fact, quiet students are often very engaged in the learning process but may need space to express their interest in ways that are suited to their quiet tendencies. This article describes how quiet students are perceived in the classroom, reviews the reasons why quiet students often serve as a source of uncertainty for college instructors, and explains a number of strategies that instructors can use to meet the learning needs of quiet students.     

The Contribution of Infant, Maternal, and Family Conditions to Maternal Feeding Competencies

OBJECTIVE: Because little is known about the role of family problem-solving processes in the development of mothers' competencies in feeding a very low birth-weight (VLBW) infant, we explored the contribution made by the competence in negotiating displayed by a mother and family member as they jointly problem solve infant-care issues. The infant's neonatal biomedical condition, maternal depressive symptoms, and family poverty status may also contribute to feeding competencies. DESIGN: A sample of 41 mothers of VLBW infants from 2 longitudinal studies who were observed during feeding at 1 and 8 months infant postterm age, with a family member of their choosing, participated in a dyadic problem-solving exercise. We assessed maternal feeding competencies with the Parent-Child Early Relational Assessment (Clark, 1997) and dyadic negotiating competence using an observational scale from the Iowa Family Interaction Rating Scales (Melby & Conger, 2001). We classified infant condition through medical record audit. Maternal depressive symptoms were assessed with the Center for Epidemiologic Studies-Depression (CES-D) Scale (L. S. Radloff, 1977), and family poverty status was determined through the mother's report of family income. RESULTS: Mothers' feeding competencies, structured into 2 factors, Parental Positive Affective Involvement, Sensitivity, and Responsiveness (PPAISR) and Parental Negative Affect and Behavior (PNAB, scored in the direction of low negativity) were stable from 1 to 8 months, accounting for the entire set of predictor variables. Neonatal biomedical condition had no effect on either PPAISR or PNAB; depressive symptoms were negatively associated with PNAB at 8 months; poverty status negatively predicted both PPAISR and PNAB at 1 and 8 months; and negotiating competence of the mother-family member dyad was positively associated with PNAB at 1 month. CONCLUSIONS: Evidence that family poverty status and dyadic negotiating competence were both associated with maternal feeding competencies supports inclusion of these family-level variables in a model of feeding competencies. A mother's negotiating competence with another family member who takes a responsible role in infant care may support maternal feeding competencies during a VLBW infant's early weeks when parenting patterns are forming.     

Paths to reading comprehension in at-risk second-grade readers

Two studies of second graders at risk for reading disability, which were guided by levels of language and functional reading system theory, focused on reading comprehension in this population. In Study 1 (n = 96), confirmatory factor analysis of five comprehension measures loaded on one factor in both fall and spring of second grade. Phonological decoding predicted accuracy of real-word reading; automatic letter naming predicted rate of real-word reading; accuracy and rate of both real-word reading (more so than decoding of pseudowords) and text reading predicted reading comprehension; and Verbal IQ also predicted reading comprehension. In Study 2 (n = 98), the treatment group (before/after school clubs receiving an integrated instructional approach that was supplementary to the general reading program) improved significantly more in phonological decoding and state standards for reading fluency than the control group (general reading program that had some code instruction but emphasized comprehension). The rate of phonological decoding explained 60.3% of real-word reading. Both treatment and control children improved significantly in reading comprehension, but controlling for pretreatment individual differences in oral vocabulary or in phonological decoding eliminated this effect. Taken together, the results of the two studies support two paths to reading comprehension: one from vocabulary and verbal reasoning, and one from written language that has multiple links between subskills: (a) alphabetic principle --> phonological decoding, (b) automatic phonological decoding --> accurate real-word reading, (c) automatic letter coding ---> automatic word reading, and (d) automatic word reading --> fluent text reading. Instructional implications of both paths and the links within the written language are discussed.     

Specific language impairment, theory of mind, and visual perspective taking: evidence for simulation theory and the developmental role of language

Recent research has found that the acquisition of theory of mind (ToM) is delayed in children with specific language impairment (SLI). The present study used a battery of ToM and visual perspective taking (VPT) tasks to investigate whether the delayed acquisition of ToM in children with SLI is associated with delayed VPT development. Harris' (1992, 1996) simulation theory predicts that the development of VPT will be delayed. Participants were 20 children with SLI (M=62.9 months) and 20 typically developing children (M=61.2 months) who were matched for nonverbal ability, gender, and age. The results supported Harris' theory and a role for language in ToM and VPT development.     

EFLM Position Statement: Our profession now has a European name: Specialist in Laboratory Medicine

We need a common name to have a clear identity which best describes the scope of the work we carry out for the patients.A clear and easily understood name which reflects the level of education and training of a specialist in the medical laboratory, and hence eligibility to be on the EC4 Register, is therefore needed, whatever academic background and whether polyvalent or sub-specialised.     

The matilda effect in science: awards and prizes in the US, 1990s and 2000s

Science is stratified, with an unequal distribution of research facilities and rewards among scientists. Awards and prizes, which are critical for shaping scientific career trajectories, play a role in this stratification when they differentially enhance the status of scientists who already have large reputations: the 'Matthew Effect'. Contrary to the Mertonian norm of universalism--the expectation that the personal attributes of scientists do not affect evaluations of their scientific claims and contributions--in practice, a great deal of evidence suggests that the scientific efforts and achievements of women do not receive the same recognition as do those of men: the 'Matilda Effect'. Awards in science, technology, engineering and medical (STEM) fields are not immune to these biases. We outline the research on gender bias in evaluations of research and analyze data from 13 STEM disciplinary societies. While women's receipt of professional awards and prizes has increased in the past two decades, men continue to win a higher proportion of awards for scholarly research than expected based on their representation in the nomination pool. The results support the powerful twin influences of implicit bias and committee chairs as contributing factors. The analysis sheds light on the relationship of external social factors to women's science careers and helps to explain why women are severely underrepresented as winners of science awards. The ghettoization of women's accomplishments into a category of 'women-only' awards also is discussed.     

Prenatal Antecedents of Newborn Neurological Maturation

Fetal neurobehavioral development was modeled longitudinally using data collected at weekly intervals from 24 to 38 weeks gestation in a sample of 112 healthy pregnancies. Predictive associations between 3 measures of fetal neurobehavioral functioning and their developmental trajectories to neurological maturation in the first weeks after birth were examined. Prenatal measures included fetal heart rate (FHR) variability, fetal movement, and coupling between fetal motor activity and heart rate patterning; neonatal outcomes include a standard neurologic examination ( n  =   97) and brainstem auditory evoked potential (BAEP; n  =   47). Optimality in newborn motor activity and reflexes was predicted by fetal motor activity, FHR variability, and somatic–cardiac coupling predicted BAEP parameters. Maternal pregnancy-specific psychological stress was associated with accelerated neurologic maturation.
