Es wird über die Entwicklung und Erprobung von Instrumenten zur Messung von Ingenieurskreativität und Fachinteresse am Studium der Elektrotechnik berichtet. Im Fall des Fachinteresses wird ein Algorithmus vorgeschlagen um effizient Skalen maßzuschneidern. Für spezifische Kreativität werden die Schwierigkeiten der Erfassung diskutiert und erste Möglichkeit der Lösung dieser Probleme diskutiert. / The development and testing of two scales measuring creativity in engineering and vocational interest is reported. Concerning the scale of vocational interest an algorithm for the efficient tailoring of such scales is proposed. In case of specific creativity the difficulties of the measurement are discussed and first solutions developed.

Although classroom assessment is one of the most frequent practices carried out by teachers in all educational programs, limited research has been conducted to investigate the dependability and validity of criterion-referenced tests (CRTs). The main purpose of this study is to develop a criterion-referenced test for first-year Japanese university students in a general English program. To this end, four research questions are formulated: (a) To what extent do the criterion-referenced items function effectively?; (b) To what extent do the facets of persons, items, sections, classes, and subtests contribute to the total score variation in two CRT forms?; (c) To what extent are two CRT forms dependable when administered as pretests and posttests?; and (d) To what extent are two CRT forms valid when administered as pretests and posttests? Two CRT forms made up of vocabulary (k = 25), listening (k = 20), and reading (k = 25) subtests were administered to 249 students using a counterbalanced design. Criterion-referenced item analyses showed that most items were working well for criterion-referenced purposes. Both univariate and multivariate generalizability studies indicated that the most of the variance was accounted for by the interaction effect, followed by the items effect, and then by the persons effect. FACETS analyses showed the separation for all the facets accounted for in the analyses and showed that item separation was greater than person separation. This indicated that the students' ability estimates were similar due to their having taken a placement test, whose results were used to form proficiency-based classes. Both univariate and multivariate decision studies indicated that the CRT forms were moderately to highly dependable. The content validity of the CRT forms was supported because the test content was strongly linked to what was taught in class. The construct validity was supported mainly because a fair amount of score gain was observed. This study elucidates how the statistical analyses used in this study can be applied to CRT development, and how CRT development can be carried out as part of curriculum development. / Educational Administration

The diploma thesis looks at the Rey-Osterrieth figure, its form, administration and its evaluation methods. The thesis describes the administration and test evaluation methods in single Czech manual made by M. Košč and J. Novák and also other used ways of scoring. The thesis attempt to present J.E. Meyers and K. R. Meyers scoring method that is also used by some Czech psychologists. The thesis deals with psychometric attributes of the test as well with emphasis on current available testing standards. One part of the thesis describes the development of some psychological functions by 12 years old children especially in relationship to abilities which are detected by Rey-Osterrieth figure. In practical part of the thesis is presented the main research which deals with procedure of making the test by twelve year old. The tests were evaluated by both mentioned methods with interpretation and analysis of its results. The thesis also looks at new preliminary standards for this age group. The test was also compared with individual results made by Číselný čtverec test.

The electrification within the automotive industry goes faster than ever, which drives an increased demand for more knowledge about batteries. Vehicle manufacturers should be able to tell how long the batteries will last and have a service program for electrified vehicles, just as there is for traditional, fuel-driven ones. Scania is in the process of developing new service methods for their hybrids and fully electrified vehicles where this thesis has been a part of this development by investigating the possibilities of having a workshop test to measure the capacity of the propulsion batteries.  During the thesis, essential parameters for cycling the batteries and measure the capacity with high accuracy have been identified and investigated by conducting lab tests. In parallel to defining the properties of a successful capacity measurement, the implementation of such a measurement at a workshop has been studied alongside a brief discussion about scheduling strategies. Conducting a capacity measurement in a workshop environment introduce new challenges, and the critical question arises, how long can the capacity measurement take? It is identified that the state of charge window size, the temperature, and the relaxation time are essential parameters to control. From the experimental part of the thesis, it can be concluded that the start temperature should lay in the range of 15-25 °C with a relaxation time of 5-10 minutes providing a satisfying accuracy. A SOC window size of 20-80% seems to be the most optimal balance between time spent and accuracy in the measurement. Furthermore, it is identified that the workshop's equipment is heavily influencing the time it takes to conduct a test. It is concluded that it is necessary to be able to charge and discharge the batteries. / Elektrifieringen av fordons industrin går snabbare än någonsin, vilket driver en högre efterfrågan på mer kunskap om batterier. Fordons tillverkare ska kunna redogöra för hur länge batterierna kan användas och ha ett service program för elektrifierade fordon, likt det som redan finns för traditionella, bränsledrivna fordon. Scania håller på att utveckla nya service metoder för sina hybrider och elektriska fordon där detta examensarbete har varit en del av denna utveckling genom att undersöka möjligheterna kring en verkstadsmetod för att mäta kapaciteten hos framdrivnings batterier.  Under examensarbetet har väsentliga parametrar för cykling av batterier och mätning av kapacitet med hög noggrannhet identifierats och undersökts med laboratorietester. Parallellt med arbetet för att definiera egenskaperna hos en precis kapacitets mätning har implementationen av en sådan mätning i en verkstad studerats tillsammans med en kort diskussion om strategier för schemaläggning av dessa tester. Det introducerar nya utmaningar att utföra kapacitets mätningen i en verkstad och den viktiga frågan uppstår, hur lång tid tar en sådan kapacitets mätning? Det har identifieras att SOC fönster storleken, temperaturen och relaxeringstiden är essentiella parametrar att kontrollera. Slutsatserna är att temperaturen bör ligga i intervallet 15-25 °C med en relaxeringstid på 5-10 minuter ger en tillfredställande noggrannhet. Ett SOC fönster motsvarande 20-80% är förefaller vara den mest optimala i avvägningen mellan tidsåtgång och precision. Vidare kan den tillgängliga utrustningen på verkstaden pekas ut som en starkt påverkande faktor till tiden det tar att utföra ett sådant verkstadstest.
