In this paper, we discuss the influence the following behaviors on the behavior by a specific student in lectures; (i) the behavior by the lecturer, (ii) the behaviors by other students, and (iii) the behavior by oneself. First, we detect features for behaviors by lecturer and students by using image processing methods. Next, the relations among the above features are approximated by neural net...

In this paper, we present an experiment conducted for comparing how experts and students assess the quality of class diagrams. Six quality attributes were addressed: Understandability, Layout, Extensibility, Modifiability, Completeness and Correctness. From this study, we aim to find out how well students are capable of evaluating the quality of UML designs. Moreover, we aim to learn which feat...

6 grade students learned about horizontal projectile motion through Compare and Contrast (CC) instruction or Invention (INV) activities using identical contrasting cases generated by a Physics Education Technology (PhET) computer simulation. Results showed that the INV treatment led to superior learning outcomes over the CC condition. Worksheet analyses revealed that CC students mainly focused ...

SIFT (Scale Invariant Feature Transform) [1] features, developed by David G. Lowe, have been found to be highly robust to translations, rotations and scaling, and have been the solution of choice for many when dealing with problems of robotic vision and object recognition. Object recognition using SIFT features involves detection of SIFT features in an image, and matching those features against...

In recent years, the growth of the profession has been exponential. Despite this growth, graduates of COMs are increasingly choosing allopathic residencies. The authors believe that this trend may stem from a lack of focus on ...
