Maternal self-efficacy and infant attachment: integrating physiology, perceptions, and behavior

48 mothers of 5-month-old infants were asked to estimate their control over the termination of an infant cry in a laboratory-simulated child-care task. Mothers who greatly overestimated their control differed from low or moderate "illusion-of-control" mothers by exhibiting a depression-prone attributional style, a depressed mood state, perceiving the father as participating less in child care, and responding to impending infant cries with heart-rate acceleration characteristic of aversive conditioning. At age 16 months, 40 of the mother-infant pairs participated in the Ainsworth Strange Situation. Insecure infant attachment at 16 months was associated with maternal perception of overcontrol, depressed mood state, and aversive conditioning to the impending cry in the laboratory task at the 5-month period.     

Increasing the Use of Student-Centered Pedagogies from Moderate to High Improves Student Learning and Attitudes about Biology

Student-centered strategies are being incorporated into undergraduate classrooms in response to a call for reform. We tested whether teaching in an extensively student-centered manner (many active-learning pedagogies, consistent formative assessment, cooperative groups; the Extensive section) was more effective than teaching in a moderately student-centered manner (fewer active-learning pedagogies, less formative assessment, without groups; the Moderate section) in a large-enrollment course. One instructor taught both sections of Biology 101 during the same quarter, covering the same material. Students in the Extensive section had significantly higher mean scores on course exams. They also scored significantly higher on a content postassessment when accounting for preassessment score and student demographics. Item response theory analysis supported these results. Students in the Extensive section had greater changes in postinstruction abilities compared with students in the Moderate section. Finally, students in the Extensive section exhibited a statistically greater expert shift in their views about biology and learning biology. We suggest our results are explained by the greater number of active-learning pedagogies experienced by students in cooperative groups, the consistent use of formative assessment, and the frequent use of explicit metacognition in the Extensive section.     

Teaching Styles of Community College Instructors

This study examined the teaching styles of online instructors at Florida's 28 community colleges in an effort to determine if the instructors had adopted the learner–centered model touted in the literature. The Principles of Adult Learning Scale was the primary instrument used to collect data from 292 online instructors. The study revealed that nearly half of the participants (n?=?135) scored in the middle range, with 84% (n?=?244) of the participants’ scores falling into the teacher-centered range. Although online distance education does have the potential to transition education from a teacher-centered orientation to a more student-centered orientation, continued efforts are needed to accomplish this shift.     

Revisiting Bloomberg's Global Product Certification Program Online: New Courses,Old Issues

In September 2006, Bloomberg L. P. implemented a new version of its Global Product Certification Program to assist users in becoming proficient on the Bloomberg Professional® Service. In doing so, it replaced the classroom-based program that had been used since 2001 as well as the online program that had been used since January 2005. Drawing on her experiences with and observations of the original online certification program, the author discusses the content and execution of the revised online program.
