This paper explores the hypothesis that using a computer network for real - synchronous discussion has noticeable effects on EFL students’ motivation language learning. Three motives emerge from the students’ responses to a survey:chatting on the Internet provides an opportunity for "real" communication; it improves personal confidence. It encourages students to overcome writing apprehension. Further analysis proves the hypothesis to a certain extent. 展开更多

Objective The aims of this study were to describe nursing students′self-directed learning readiness and social problem solving and test their correlations in Macao.Methods This descriptive cross-sectional study was conducted on 140baccalaureate nursing students.A stratified random sampling was performed.The Self-directed Learning Readiness(SDLR)Scale and Chinese Social Problem-Solving Inventory-Revised(C-SPSI-R)were used.Results The response rate was 79.3%.Students possessed readiness for self-directed learning(mean 149.09±12.53,51.4%at high level,48.6%at low level).Regarding to social problem solving,the mean scores of each subscale were 9.35±3.25(Rational Problem Solving,RPS),10.26±3.23(Positive Problem Orientation,PPO),8.14±4.06(Negative Problem Orientation,NPO),5.67±4.44(Avoidance Style,AS),and 4.84±3.03(Impulsivity/Carelessness Style,ICS).SDLR was positively related to RPS and PPO,but was negatively related to AS.Conclusion Half of students possessed stronger readiness for self-directed learning.Students had a belief in the ability to solve problems,and adopted relevant strategies in solving problems.However,students still had negative and dysfunctional orientation and defective attempts in solving problems.Self-directed learning was positively related to positive and constructive orientation,but was negatively related to defective problem-solving pattern.Nurse educators should create educational climates for promoting student confidence and mutual responsibility for learning and their thinking process for problem solving. 展开更多

To explore the adoption of formative assessment in oral English test Validity study of oral test scores was performed in PhD candidates of 2011.Through linear relevance analysis,it is concluded that the relevance coefficient between oral score and overall score is 0.751 (P <0.001),the relevance coefficient between oral score and listening score is 0.530 (P <0.001),and the results indicate overall score and listening score have a positive relevancy with oral score.The result showed a positive correlation of oral test scores with written examination scores.Questionnaires modeled with the 5-point Likert Scale revealed a moderate supportive attitude of students on this formative assessment.The results are:80.1% of students indicated they feel satisfied and very satisfied with such oral English evaluation form,77.9% of students consider this oral score reflects their real oral English proficiency.This indicates that most students feel satisfied about the form and score in this oral exam.Through effective combination between formative evaluation method and summative evaluation method,it can effectively coordinate the relation between teaching and learning in oral English teaching practice,stimulate students'study initiative,and play a positive role in improving students'overall oral English proficiency. 展开更多

Objective: To explore how relaxation reduce the effect of stress in Iranian nursing students.Methods: A total of 40 nursing students were randomly selected and divided into two groups of test and control each with 20 students.An exam questionnaire consisting of the stress test of Spilberger and control of physiological determinants(blood pressure,pulse respiration,temperature) was performed to two groups.The practice of relaxation continued for two weeks and three times a day.Data were collected and analysed using t-test and Chi-square.Results: Two groups did not show any difference in relation to the average of physiological determinants before and after investigation.However,pulse was significantly different between the two groups.The average scores of stress before and after relaxation were significantly differed between the two groups investigation so that the level of stress was reduced in the test group(t= 2.5,df =39,P= 0.02).Conclusion: To alleviate stressors associated with clinical practice and create a healthy work environment for practice it is recommended that nursing students have some relaxation before entering practical environments. 展开更多
