Dynamische Probleml?sekompetenz

This article is about the importance and validity of dynamic problem solving (DPS) in predicting technical problem solving performances. In addition to DPS, fluid intelligence and technical knowledge were included in the study. Assessing DPS and fluid intelligence simultaneously also allowed for testing the empirical distinction between both constructs. Results are based on data of a sample of car mechatronics (n?=?129) and electronics technicians (n?=?88) and showed that DPS and fluid intelligence were empirically separable. In the first sample (electronics technicians) DPS explained technical problem solving performance best, although fluid intelligence showed incremental validity too. In the second sample (car mechatronics) fluid intelligence was weakly related to the criterion whereas DPS was not at all. When technical knowledge was added to the prediction, both DPS and fluid intelligence did not predict technical problem solving performance. However, in the sample of the electronics technicians fluid intelligence indirectly affected the criterion through technical knowledge. A discussion of the somewhat contradictory results, the different results patterns in the two samples and a theoretical explanation of the results are provided.     

Reduction of mental distress in the dissection course by introducing the body donor experience through anatomical demonstrations of organ systems

The practice of dissection teaches students not only the foundations of anatomical knowledge but also encourages the development of professional competencies. Yet, the dissection of cadavers in the gross anatomy course can be a stress factor for medical students. There are a minor proportion of students who demonstrate strong emotional reactions in anticipation of being confronted with a cadaver. Therefore, in 2008, the authors implemented a voluntary course entitled, “Anatomical demonstrations of organ systems” (AD‐OS) in advance of the dissection course to ease this psychological burden. The question of whether attendees of AD‐OS showed less mental distress at the start of the dissection course compared with those that had not or only infrequently visited AD‐OS was addressed. AD‐OS attendees assessed their expected mental distress using a five‐point Likert scale before starting the dissection course and a second time at the end of their first day, after they had been confronted with a cadaver. AD‐OS was evaluated as excellent and the majority of students participated actively during teaching sessions. Overall, female students showed higher levels of mental distress. AD‐OS attendees assessed themselves as being less burdened by mental distress than members of the control group. Longitudinal analysis revealed that students who visited AD‐OS showed a marked decrease of their mental distress level, comparing prospective and retrospective ratings. This was significantly (P < 0.001; Z = ?6.061) different from nonattendees or those who visited AD‐OS only infrequently. AD‐OS satisfied its intended teaching goals and proved that a step‐by‐step introduction of dissection through anatomical demonstrations helped to reduce the mental distress of students. Future studies are planned to measure mental distress with objective instruments. Anat Sci Educ © 2012 American Association of Anatomists.     

Corporal punishment and children's externalizing problems: A cross-sectional study of Tanzanian primary school aged children

The adverse effect of harsh corporal punishment on mental health and psychosocial functioning in children has been repeatedly suggested by studies in industrialized countries. Nevertheless, corporal punishment has remained common practice not only in many homes, but is also regularly practiced in schools, particularly in low-income countries, as a measure to maintain discipline. Proponents of corporal punishment have argued that the differences in culture and industrial development might also be reflected in a positive relationship between the use of corporal punishment and improving behavioral problems in low-income nations. In the present study we assessed the occurrence of corporal punishment at home and in school in Tanzanian primary school students. We also examined the association between corporal punishment and externalizing problems. The 409 children (52% boys) from grade 2 to 7 had a mean age of 10.49 (SD = 1.89) years. Nearly all children had experienced corporal punishment at some point during their lifetime both in family and school contexts. Half of the respondents reported having experienced corporal punishment within the last year from a family member. A multiple sequential regression analysis revealed that corporal punishment by parents or by caregivers was positively related to children's externalizing problems. The present study provides evidence that Tanzanian children of primary school age are frequently exposed to extreme levels of corporal punishment, with detrimental consequences for externalizing behavior. Our findings emphasize the need to inform parents, teachers and governmental organizations, especially in low-income countries, about the adverse consequences of using corporal punishment be it at home or at school.     

In-class examinations in college-level science: New theory,new practice

Every faculty member knows that exams drive student behavior. Testing and grading are part of every course, but generally of lesser importance to faculty members than course content itself. Recently, instructional methods and pedagogy. But as issues of grade inflation, student attrition, accountability, and authentic assessment grow in importance, we see some interesting innovations in testing methods and some interesting innovations. The authors are publishing a collection of some of these as described in their own words, by faculty themselves. Two questions underlie the study: 1) why is it so difficult to change tests and testing traditions in college-level science and 2) will the enormous efforts underway to reform pedagogy and curriculum in these disciplines have any lasting effect if testing does not have a prominent place on the reform agenda?     

Emotions and the liminal space in entrepreneurship education

ABSTRACT

Emotions are present in all learning processes, including those in entrepreneurship education. In this paper, we investigate which kinds of emotions exist in entrepreneurship education at university and in which contexts they occur, and show how the concept of liminal spaces – spaces of transformation in which students encounter high degrees of uncertainty, while their potential for learning is maximised – can be used in order to understand the role of negative emotions for entrepreneurship education. Providing examples from courses on entrepreneurship for Engineering and Business Administration students at a German university, we are able to confirm findings of existing literature on the type and sources of emotions. Moreover, our findings suggest that reflection of students on emotional processes that involve the endurance of uncertainty contribute significantly to the achievement of learning outcomes and that – within the limits of existing learning cultures and guidelines for assessment – teachers can facilitate such processes.     

Wer liegt am Ende der Grundschulzeit vorn?

The number of students enrolled in private schools has been growing continuously in the past years, especially in elementary schools. There is a variety of reasons for this development. Among other expectations, parents anticipate a superior education for their children and hope for bigger academic success. However, empirical results on the effectiveness of private schools are inconsistent and ambiguous, partly because many studies used cross-sectional data. Longitudinal studies investigating the development of elementary school students are especially lacking.The present study compares academic achievement gains of students enrolled in public schools to students who learned in the so-called BIP-creativity elementary schools. BIP schools are private schools that aim to promote the development of the talent, intelligence and personality of their students. This study investigates the development of students in mathematics, reading and orthography over a 4-years period.As the group of BIP-students is selected in terms of their socio-economic background, analyses were run in two ways. First, multilevel analyses controlling for student and class characteristics were performed. Second, a Propensity Score Matching based on school enrollment data was used in order to select a comparable group of students from public schools. Each BIP-student was matched to a student from the public schools that had a comparable socio-economic background and similar cognitive characteristics. Neither multilevel analyses nor mean comparisons of the matched samples could reveal any differences between the two groups of students in the three domains of academic achievement at the end of fourth grade.     

Faculty research productivity 1972–1988: Development and application of constant units of measure

The economic concept ofreal orconstant units of measure is utilized to assess the rate of inflation/deflation of opportunity for publication between 1972 and 1988 for the disciplines of biology, psychology, and English. Data for the study came from (1)Ulrich's International Periodicals Directory; (2)Annual Bibliography of English Language and Literature; (3)American Universities and Colleges; (4) 570 journal issues across the three disciplines; and (5) national surveys of faculty conducted in 1972, 1980, and 1988. Based on changes over time in the amount of space in which faculty can publish their research and the number of individuals competing for that space, indexes are developed that convert 1988 publication counts into 1972 equivalents. Results indicate inflation rates of 103, 85, and -45 percent for biology, psychology, and English, respectively, between 1972 and 1988. Due to these rates, faculty had to produce 14.65, 5.05, and 1.18 articles, respectively, in the two years prior to 1988 to have been as productive inreal articles as they were in the two years prior to 1972.
