Attitudes Toward Retarded Children: Effects of Evaluator's Psychological Adjustment and Age

Gottlieb, J. (1969). Attitudes Toward Retarded Children: Effects of Evaluator's Psychological Adjustment and Age. Scand. J. Educ. Res. 13, 170‐182. Norwegian school children between the ages of 8‐10, 10‐12, 12‐14, and 14‐16 were divided into high and low adjustment groups on the basis of discrepancy scores between their ideal self and self scores on the semantic differential. It was hypothesized that the high adjustment group would report more favorable attitudes toward the retarded than the low adjustment group, and that attitudes would remain relatively stable with increased age. Both hypotheses were confirmed. The results were interpreted as supporting Rogers’ theory. Possible explanations for the over‐all favorable attitudes by the Norwegian Ss were also discussed.     

Improving the Cultural Competency of Social Work Students With a Social Privilege Activity

This article describes the development and utilization of an instructional activity created by the authors for the purposes of preparing social work students for culturally competent practice with members of historically oppressed populations. Experiential activities in the classroom provide an alternative approach to traditional pedagogical methods by positioning the learner at the center of an educational process that is grounded in reality. The activity is designed to highlight the social privileges of individuals and the inherent risks that are taken when deciding to challenge or confront oppressive structures, attitudes, and behaviors.     

Examining the effect of teachers' adaptations of a middle school science inquiry‐oriented curriculum unit on student learning

Reform based curriculum offer a promising avenue to support greater student achievement in science. Yet teachers frequently adapt innovative curriculum when they use them in their own classrooms. In this study, we examine how 19 teachers adapted an inquiry‐oriented middle school science curriculum. Specifically, we investigate how teachers' curricular adaptations (amount of time, level of completion, and activity structures), teacher self‐efficacy (teacher comfort and student understanding), and teacher experience enacting the unit influenced student learning. Data sources included curriculum surveys, videotape observations of focal teachers, and pre‐ and post‐tests from 1,234 students. Our analyses using hierarchical linear modeling found that 38% of the variance in student gain scores occurred between teachers. Two variables significantly predicted student learning: teacher experience and activity structure. Teachers who had previously taught the inquiry‐oriented curriculum had greater student gains. For activity structure, students who completed investigations themselves had greater learning gains compared to students in classrooms who observed their teacher completing the investigations as demonstrations. These findings suggest that it can take time for teachers to effectively use innovative science curriculum. Furthermore, this study provides evidence for the importance of having students actively engaging in inquiry investigations to develop understandings of key science concepts. © 2010 Wiley Periodicals, Inc., J Res Sci Teach 48: 149–169, 2011     

Developmental continuity in theory of mind: speed and accuracy of belief-desire reasoning in children and adults

On belief-desire reasoning tasks, children first pass tasks involving true belief before those involving false belief, and tasks involving positive desire before those involving negative desire. The current study examined belief-desire reasoning in participants old enough to pass all such tasks. Eighty-three 6- to 11-year-olds and 20 adult participants completed simple, computer-based tests of belief-desire reasoning, which recorded response times as well as error rates. Both measures suggested that, like young children, older children and adults find it more difficult to reason about false belief and negative desires than true beliefs and positive desires. It is argued that this developmental continuity is most consistent with either executive competence or executive performance accounts of the development of belief-desire reasoning.     

Are there long-term effects of early child care?

Effects of early child care on children's functioning from 4(1/2) years through the end of 6th grade (M age=12.0 years) were examined in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (n=1,364). The results indicated that although parenting was a stronger and more consistent predictor of children's development than early child-care experience, higher quality care predicted higher vocabulary scores and more exposure to center care predicted more teacher-reported externalizing problems. Discussion focuses on mechanisms responsible for these effects, the potential collective consequences of small child-care effects, and the importance of the ongoing follow-up at age 15.     

Comparative Study of Serum Amylase and Lipase in Acute Pancreatitis Patients

To establish utility of single enzymatic marker for the diagnosis of acute pancreatitis. This is a cohort study. Tertiary care centre proven cases of acute pancreatitis (n = 50) admitted in surgery ward between December 2011 and May 2013 were included in the study. Serum amylase and lipase were performed along with many analytes. All relevant data including serum lab values and imaging were collected. All 50 patients included in the study had raised serum lipase, 42 patients had both amylase and lipase raised, 8 patients had amylase normal but lipase raised. In smaller hospitals where limited lab and radiological facilities are available, estimation of serum lipase will be a better choice over serum amylase in diagnosis of acute pancreatitis.     

Golfers do not respond to changes in shaft mass properties in a mechanically predictable way

A common belief in the golf community is that a lighter shaft allows the golfer to swing the club faster. From a mechanical point of view, reducing the mass of the shaft would result in a faster swing. However, a golfer is not a purely mechanical system, and so it is simplistic to assume that identical loads will be applied when swinging different clubs. Therefore, the purpose of this study was to test the hypothesis that golfers behave similar to a mechanical model when swinging clubs of varying mass. A torque driven model estimated the effects caused by the addition of 22?g to the shaft. Twelve golfers hit balls with a standard driver as well as a driver fitted with the same 22?g increase in mass. Club kinematics were collected with a high-speed motion capture system. The model predicted a 1.7?% lower club head speed for the club with additional mass. One subject showed a similar reduction (1.4?%), but one subject showed an increase in club head speed by 3.0?%. Ten subjects did not show any significant differences. These results suggest that golfers do not respond to changes in club mass in a mechanically predictable way.     

The influence of golf club shaft stiffness on clubhead kinematics at ball impact

The role of shaft stiffness on the golf swing is not well understood. Studies in which golfers hit balls with clubs of varying shaft flex have reported changes in ball distance. The results of mathematical models suggest that shaft stiffness affects only the orientation of the clubhead at impact, not the speed of the clubhead, but there are no experimental results validating these findings. The purpose of this study was therefore to experimentally examine the influence of shaft stiffness on clubhead kinematics at ball impact. Forty golfers hit 10 balls with each of five drivers varying in shaft stiffness from 'Ladies' to 'Extra-Stiff', in a double-blind study design. The motions of three reflective markers attached to the clubhead were captured with a high-speed motion analysis system. At ball impact, shaft stiffness had a statistically significant influence on clubhead speed for 27 subjects, on loft angle for 11 subjects, and on lie angle for all 40 subjects. No effect was observed on face angle, in to out path angle, or attack angle. These results show that shaft stiffness can affect ball launch conditions by altering clubhead speed and/or loft angle.     

The impact of high-stakes testing on student proficiency in low-stakes subjects: Evidence from Florida's elementary science exam

An important criticism of high-stakes testing policies – policies that reward or sanction schools based on their students’ performance on standardized tests – is that they provide schools with an incentive to focus on those subjects that play a role in the accountability system while decreasing attention to those subjects that are not part of the program. This paper utilizes a regression discontinuity design to evaluate the impact of Florida's high-stakes testing policy on student proficiency in the low-stakes subject of science. We confirm prior results that students in schools facing more immediate sanctions under the policy made substantial gains in the high-stakes subjects of math and reading. Contrary to the crowding-out hypothesis, we find that students in these schools made substantial achievement gains in the low-stakes subject of science as well.
