  abstract  = {In diesem Beitrag m{\"o}chten wir einen Gedanken des amerikanischen Mathematikers Paul Halmos aufgreifen und konkretisieren. Wir m{\"o}chten verdeutlichen, dass {\"o}konomisches Denken nicht abstrakt gelehrt, sondern „erfahren" werden muss, wenn es nachhaltig und in seiner ganzen Breite gef{\"o}rdert werden soll. Dazu dienen kognitiv aktivierende Aufgaben. Was man darunter versteht und welche Funktionen und Qualit{\"a}tsmerkmale Aufgaben in der {\"o}konomischen Bildung besitzen, verdeutlichen wir in den Abschnitten 1 und 2. Im Praxisteil (Abschnitte 3 bis 8) werden konkrete, unterrichtlich erprobte Beispielaufgaben vorgestellt, mit denen {\"o}konomisches Denken erfolgreich gef{\"o}rdert werden kann. Unser Beitrag schließt mit einer kurzen Skizze wirtschaftsdidaktischer Implikationen (Abschnitt 9).},

  abstract  = {Objective: We investigated the effects of combined balance and strength training on measures of balance and muscle strength in older women with a history of falls. Methods: Twenty-seven older women aged 70.4 ± 4.1 years (age range: 65 to 75 years) were randomly allocated to either an intervention (IG, n = 12) or an active control (CG, n = 15) group. The IG completed 8 weeks combined balance and strength training program with three sessions per week including visual biofeedback using force plates. The CG received physical therapy and gait training at a rehabilitation center. Training volumes were similar between the groups. Pre and post training, tests were applied for the assessment of muscle strength (weight-bearing squat [WBS] by measuring the percentage of body mass borne by each leg at different knee flexions [0°, 30°, 60°, and 90°], sit-to-stand test [STS]), and balance. Balance tests used the modified clinical test of sensory interaction (mCTSIB) with eyes closed (EC) and opened (EO), on stable (firm) and unstable (foam) surfaces as well as spatial parameters of gait such as step width and length (cm) and walking speed (cm/s). Results: Significant group × time interactions were found for different degrees of knee flexion during WBS (0.0001 < p < 0.013, 0.441 < d < 0.762). Post hoc tests revealed significant pre-to-post improvements for both legs and for all degrees of flexion (0.0001 < p < 0.002, 0.697 < d < 1.875) for IG compared to CG. Significant group × time interactions were found for firm EO, foam EO, firm EC, and foam EC (0.006 < p < 0.029; 0.302 < d < 0.518). Post hoc tests showed significant pre-to-post improvements for both legs and for all degrees of oscillations (0.0001 < p < 0.004, 0.753 < d < 2.097) for IG compared to CG. This study indicates that combined balance and strength training improved percentage distribution of body weight between legs at different conditions of knee flexion (0°, 30°, 60°, and 90°) and also decreased the sway oscillation on a firm surface with eyes closed, and on foam surface (with eyes opened or closed) in the IG. Conclusion: The higher positive effects of training seen in standing balance tests, compared with dynamic tests, suggests that balance training exercises including lateral, forward, and backward exercises improved static balance to a greater extent in older women.},

  abstract  = {W{\"a}hrend die theoretische Arbeitsbeschreibung und das Rollenbild von Schulleitern vielfach in der Forschung aufgegriffen wurde, gibt es - wie {\"u}brigens im gesamten Bereich Public Management - nur wenige empirische Untersuchungen, die aus einer betriebswirtschaftlichen Managementbetrachtung heraus untersuchen, was Schulleiter wirklich machen, d.h. welchen T{\"a}tigkeiten und Aufgaben die genannten Personen nachgehen und welche Unterschiede sich feststellen lassen. Besondere Relevanz erh{\"a}lt die Thematik durch das sich wandelnde Aufgabenbild des Schulleiters, getrieben insbesondere durch die zus{\"a}tzliche Autonomie der Einzelschule, aber auch durch die Fokussierung auf die Performance und Wirksamkeit der Einzelschule und verbunden damit, die Abh{\"a}ngigkeit dieser von der Arbeit des Schulleiters. Hier bildet das Verst{\"a}ndnis der Aufgaben und T{\"a}tigkeiten eine wichtige Grundlage, die jedoch unzureichend erforscht ist. Mit Hilfe einer explorativen Beobachtung von 15 Schulleiterinnen und Schulleitern und damit einer empirischen Untersuchung von insgesamt 7591 Arbeitsminuten und 774 Aktivit{\"a}ten in Kombination mit ausf{\"u}hrlichen qualitativen, halboffenen Interviews wird durch diese Arbeit eine detaillierte Betrachtung des tats{\"a}chlichen Schulleitungsmanagementhandelns m{\"o}glich. So wird sichtbar, dass sich die Aufgaben und T{\"a}tigkeiten der Schulleiter in zentralen Bereichen unterscheiden und eine Typologisierung entlang von Rollenbeschreibungen und Leadership Behavior zu kurz greift. Es konnte zum ersten Mal in dieser Ausf{\"u}hrlichkeit innerhalb des deutschen Schulsystems gezeigt werden, dass Schulleiter Kommunikationsmanager sind. Dar{\"u}ber hinaus entwickelt das hier dokumentierte Forschungsvorhaben Hypothesen zu den Faktoren, die einen Einfluss auf die Aufgaben und T{\"a}tigkeiten haben und beschreibt dezidiert Implikationen, die diese Erkenntnisse auf die T{\"a}tigkeit des Schulleiters, die weitere Forschung aber auch die politische Rahmengestaltung und, damit verbunden, die Weiterentwicklung des Schulsystems haben.},
