Fabrication, characterization and application of micro-/nano-rods/wires are among the hottest topics in materials science and applied physics. Micro-/nano-rod-based structures and devices are developed for a wide-ranging use in various fields of micro-/nanoscience (e.g. biology, electronics, medicine, optics, optoelectronics, photonics and sensors). It is well known that the structure and prope...

Measurement theories are important to practice in educational measurement because they provide a background for addressing measurement problems. One of the most important problems is dealing with the Measurement Errors. A good theory can help in understanding the role of errors they play in measurement; (a) To evaluate the examinee's ability to minimize errors and (b) Correlations between varia...

There are two currently popular statistical frameworks for addressing measurement problems namely Classical Test Theory (CTT) and Item Response Theory (IRT). This study is aimed empirically to examine the similarities and differences in the parameters estimated using these two frameworks. For this purpose, firstly the model assumptions and the goodness of fit analyses were checked for IRT. The ...
