First year students' perceptions of excellent teachers

The purpose of this study is to examine the characteristic of a excellent lecturer as perceived by the first year students of Malay Woman Training Institute the similarities and differences in the responses based on education level. Knowing what characteristics are correlated with excellence in teaching is important because it provides both pre-service and in-service teachers with an opportunity to evaluate their own teaching, receive feedback from students, and improve teaching. Also, this knowledge aids teacher preparation programs in designing their courses and in recruiting the best candidates for teaching. This will help the Teacher Education Division in modifying the curriculum to enhancing specific skills that a teacher must possess. Two distinct samples were involved in this study: For the (5-point) Likert scale, data will be collected from a group of 56 post graduate students from local university and 205 O' level school leavers from Malay Women Teachers' Institute in Malacca. Data analysis using SPSS version 14 through comparing means frequency, percentage, t-test and One-Way ANOVA. The findings of this study indicate that good leader is an important characteristic that contributes to excellent teachers. More than 90% of the students agree that the teaching skills such as motivation, learning environment, facilitating learning, instructional approach and enhancement of student learning with technology should be present in an excellent teacher. .The comparison of the two means shows that students agreed that personal traits are more important than teaching skills in making an excellent teacher. There is no significant difference in the perceptions of excellent teachers between postgraduates and undergraduates students. The findings indicate that what matters most is employing a variety of teaching styles, positive attitude, establish a closer rapport with student can provide a better and conducive environment for learning. Lecturers must be more open to criticism, suggestions and constructive comments in other to change and adjust their personal traits to be a better person

On Locality of Schmidt-Correlated States

We review some results on the equivalence of quantum states under local unitary transformations (LUT). In particular, the classification of two-qubit Schmidt correlated (SC) states under LUT is investigated. By presenting the standard form of quantum states under LUT, the sufficient and necessary conditions of whether two different SC states are local unitary equivalent are provided. The correlations of SC states are also discussed.Comment: 14 page

Information asymmetry, trading volume and returns in the Malaysian stock market

This paper examines investors’ motive to trade on the Malaysian stock market from 1st July 1997 to 30th June 2005. By applying ordinary least square (OLS) to 272 stocks as well as in three size groups, both the time series and cross-sectional results indicate that speculation on firm specific asymmetric information is the primary motive to trade on Malaysian stock market for the full and two sub-sample periods. The results show that most of the investors in Malaysian stock market tend to speculate firm related information to maximize their profits. The findings of this study provide important implications to policy makers in addition to investors in this developing market. Proper management of foreign portfolio investment is crucial to prevent manipulative moves and excessive speculative forms of portfolio investments that may cause excessive surges of inflows and massive panic outflows of short-term capital and thus collapse the financial system and downturn economy
