The free-responsequestion which tested year-12 circuit analysis was correctly answered by only 11% of thestudents, while the free-response question which tested year-11 algebraic manipulation wascorrectly answered by only 60% of the students.

: 2 ℎ = lnHere ε is the total permittivity, h is the axial height, and b and a are the outer and inner radiirespectively. We take advantage of the fact that when the capacitor is empty (air filled) thepermittivity is ε ≈ ε0 since the dielectric constant (relative permittivity) is εr ≈ 1. As the capacitorspace between the conductors is filled with water the total capacitance can be viewed as theparallel combination of a water filled capacitor (dielectric constant εr ≈ 80) of height z with an airfilled capacitor of height h – z. The result is the sum of two regions. 2 (80) 2 (ℎ − ) 2

above, it may be concludedthat 36% of students showed an awareness of Newton’s third law. By contrast, 53% of studentschose answer (b), believing that the larger current would exert a stronger force. Similar resultswere obtained by Maloney et al1 in testing students enrolled in general-physics courses: about45% of both algebra-based and calculus-based students answered (b) in both the pretest and theposttest. Encouragingly, Maloney et al did find an improvement from the pretest to the posttestfor option (c), 7% versus 22% for the calculus-based students.Another year-two pretest question asked students to compare the forces that unlike, unequalpoint charges exerted on each other. Students were not offered the distractor choice of unlikecharges

precisely. Moreover, many textbook definitionsare not accurate or complete for the case of series elements, leading to many misconceptions.For example, students may think that elements must have a node in common to be in series,when they need not! Both elements can be part of a series chain of elements, without directly Page 26.158.6sharing any node. A complete definition states that: a) Two elements are in series if one (andonly one) end of each element is attached to a common node, and no other conducting element isattached to that node (or, equivalently, that a node connects one end each of exactly twoconducting elements); and b) If elements A

illustrated with the ct_conv function. (Note: Several texts define sinc(t) as sin(t)/(t), thedefinition being using here is the same as that used by MATLAB.) For example the convolutionof f1(t) = a sinc(a t) with itself is equal to f1(t), i.e. f1(t) is an idempotent of convolution. Moregenerally, when f1(t) = a sinc(a t) and f2(t) = b sinc(b t) then f1(t) * f2(t) = f1(t) if ab. Theseproperties are trivial to derive in the frequency domain (the transform of a sinc(a t) isrect(ω/2πa)), but are very difficult to derive in the time domain via direct evaluation of theconvolution integral. This result is often unexpected by Figure 10 shows the result of usingct_conv to verify the previous property with a = 1 and b = 2. The theoretical result and

A comparison of the lab practicum grades between these two partitions of thecontrol group yielded no significant difference. However, in the solo group there was astatistical difference between the A-B and C or less partitions (D=0.33 and p<0.05). Thecumulative distribution functions for the combined control group and

This effort utilized teaching-learning interviews in a Spring2010 linear systems course to (a) identify the conceptual difficulties that students face whenstudying Fourier series and (b) improve students’ understanding of this topic. These interviewsattempted to focus more on higher-level Fourier series concepts (consistent with levels 4 through6 in Bloom’s taxonomy) and less on the procedural calculations and plotting (levels 1
