Predictive Utility and Achievement Outcomes of Two Simultaneous District-Developed Interim Assessment Programs

Chen, Tavymae W 01 January 2014 (has links)
The purpose of the present correlational, ex post facto study was to evaluate the predictive ability and academic achievement criterion outcomes of two district-developed interim mathematics assessment programs for a sample of 5,801 grade 6 students in a large urban school district. Average scores for both interim assessment types were statistically significantly more related to 2013 FCAT 2.0 scores (r = .75 and .72; p < .001) than all other predictors (i.e., student demographics, Florida school grade, and student course GPA) except for 2012 FCAT 2.0 scores (r = .78; p < .001). Further, the newer interim assessment program with an instructional purpose and curriculum-based sequencing had slightly stronger overall predictive power (rs = .88) and a higher criterion mean score (M = 218.08) than the older, state-test mirror interim assessment program (rs = .85; M = 215.47). Regression models by prior year FCAT 2.0 Achievement Level yielded some predictor ranking discrepancies by prior achievement level. Although not statistically significant at the .01 level, groups of students with a more moderate total number of interim assessments outperformed groups with all or nothing. Overall, the two types of interim assessment programs evaluated in the present study were good predictors of the state high-stakes test, 2012 Grade 6 Mathematics FCAT 2.0. However, more research must be done to identify with certainty whether or not the act of taking the interim tests and receiving feedback contributes to improved student learning.

Metody pro testování analogových obvodů / Methods for testing of analog circuits

Kincl, Zdeněk January 2013 (has links)
Práce se zabývá metodami pro testování lineárních analogových obvodů v kmitočtové oblasti. Cílem je navrhnout efektivní metody pro automatické generování testovacího plánu. Snížením počtu měření a výpočetní náročnosti lze výrazně snížit náklady za testování. Práce se zabývá multifrekveční parametrickou poruchovou analýzou, která byla plně implementována do programu Matlab. Vhodnou volbou testovacích kmitočtů lze potlačit chyby měření a chyby způsobené výrobními tolerancemi obvodových prvků. Navržené metody pro optimální volbu kmitočtů byly statisticky ověřeny metodou MonteCarlo. Pro zvýšení přesnosti a snížení výpočetní náročnosti poruchové analýzy byly vyvinuty postupy založené na metodě nejmenších čtverců a přibližné symbolické analýze.
