Effects of mobile apps for nursing students: learning motivation,social interaction and study performance

Abstract

This study examined the effects of mobile apps on the learning motivation, social interaction and study performance of nursing students. A total of 20 students participated in focus group interviews to collect feedback on their use of mobile apps for learning and communicative activities. Two consecutive cohorts of students in a nursing programme, each with about 200 students, were recruited for assessing their learning motivation through a survey and study performance by two tests. The results showed that the students actively used the mobile apps for studying supplementary materials as well as participating in in-class activities and clinical assessments. The students had a relatively high level of motivation for performing and learned well, but relatively low perceived satisfaction and self-efficacy with mobile learning. They showed better study performance after practising mobile learning. The results also suggest that students’ perceived intrinsic value with mobile learning has to be enhanced for improving study performance.     

Collaborative inquiry project-based learning: Effects on reading ability and interests

The academic performance of students has been shown to be associated with reading ability. Inquiry learning can potentially enhance the reading abilities and interests of students. This study verified this proposition by examining the effects of an inquiry approach to group projects on the reading abilities of primary school students. Using a case study design, an inquiry project-based learning (PBL) approach, with the collaboration between three types of teachers and the school librarian was implemented to support the development of reading abilities and interests of students in a primary school in Hong Kong. The participants included Primary 4 students, teachers, and parents. Progress in International Reading Literacy Study (PIRLS) tests were used to evaluate the students' reading abilities; survey questionnaire and interviews were used to examine the participants' perceptions of the inquiry PBL; and the PIRLS survey was used to measure the students' attitudes and self-perceptions. Quantitative and qualitative data analyses showed positive effects on the reading abilities and attitudes of the participating students. Students' attitudes and self-perceived abilities appeared to influence the improvements in reading abilities. Finally, improvements in the students' reading comprehension, reading speed, and vocabulary were perceived. These findings provide evidence and insights to support further implementation of inquiry PBL in primary schools.     

Using a theoretical model of communal coping to understand changes in language brokers’ coping patterns: Implications for Latina/o early adolescents’ brokering stress and efficacy

Language brokering occurs when immigrant youth linguistically and culturally mediate for family and members of U.S. mainstream culture. Under some circumstances, brokering can be stressful. Based on a theoretical model of communal coping, this study utilized two waves of survey data from 342 Latina/o sixth- to eighth-grade students to identify different types of copers: (a) communal copers, (b) tentative copers, and (c) declined-ownership copers. Communal copers reported greater brokering stress than tentative brokers in the middle of the year, but not by the end of the year. Communal copers reported greater brokering efficacy than tentative copers in the middle and end of the year. Declined-ownership copers consistently had the lowest brokering stress and moderate brokering efficacy.     

Hope communication as a predictor of documented and undocumented Latina/o high school students’ college intentions across an academic year

Drawing from hope theory, we examined whether hope communication predicted undocumented and documented U.S. Latina/o youth’s college intentions across an academic year. With three waves of survey data from 172 documented and 253 undocumented Latina/o high school students, auto-regressive cross-lagged analyses revealed that parent, teacher, and friend hope communication at the beginning of the year indirectly increased students’ college intentions by the end of the year. A trend emerged whereby undocumented students reported significantly less hope communication and weaker college intentions than documented students within most of the waves. Our findings suggest that hope communication has the potential to increase the educational, economic, and social mobility of Latina/o immigrant students by increasing their intentions to attend college.     

Cross‐national Comparisons in the International Successful School Principalship Project (ISSPP): The USA,Norway and China

This article provides a cross‐national perspective on successful school principalship in three countries derived from an analysis of case studies in the International Successful School Principalship Project (ISSPP). The ISSPP aims to investigate the characteristics, processes and effects of successful school leadership across eight countries (i.e. Australia, Canada, England, the United States, China, Denmark, Sweden and Norway). Examples from the USA, Norway and China (Shanghai) were selected to illustrate cross‐national differences related to the societal purposes of education, the structure and funding of different national educational systems and the influence of particular governmental educational policies (i.e. accountability‐oriented policies) on the leadership practices of individual school principals. Variations in selection criteria and research procedures were also noted. Recommendations for further research using a cultural framework include analysing multiethnic schools to identify culturally specific leadership practices as well as developing further ISSPP case studies in non‐Western contexts.     

Raising Health Literacy and Promoting Empowerment to Meet the Challenges of Aging in Hong Kong

This study aimed to determine the educational needs of members of the public and related professional disciplines in order to improve health literacy in elderly issues. A cross-sectional survey was conducted in 2007; 2,694 subjects were recruited from the noninstitutional Hong Kong population aged 16 years and over. Undergraduate students of health care professions, professionals working at the hospitals, and the seniors were purposefully over-sampled. Results showed significant knowledge gaps and misconceptions. The gaps were more prevalent with increasing age in general, although they also existed among health care professionals. Public education should target the revealed areas of knowledge gaps and misconceptions.     

E-Learning in China

The success of any open and distance learning course depends on how well it is designed, executed, and evaluated. Evaluation of a course not only demonstrates its strengths, but also points out any inherent shortcomings in the course. This is why course evaluation constitutes an important function in an open and distance learning system. The present paper aims to evaluate a distance education course ‘Instruction in higher education’ from the Postgraduate Diploma in Higher Education (PGDHE) offered by the Indira Gandhi National Open University (IGNOU), India. Feedback on this course was obtained from 230 respondents with the help of a structured questionnaire. The data collected from students were analysed using percentages. Findings from the study provide an understanding of the operation of the different components of the course. While the majority of the respondents were satisfied with self‐instructional materials, assignments, the extended contact programme, and delivery mechanisms, a sizeable number of respondents were dissatisfied with academic counselling, and the use of audio‐video programmes. Generally, the respondents provided useful feedback and suggestions which will help the faculty in course revision.     

English Language Teaching in East Asia Today: An Overview

The paper is structured in three parts. Part 1 discusses the position and status of English in 15 countries or education systems in East Asia, with the term East Asia used to cover Southeast and Northeast Asia. Part 2 of the paper is devoted to recent developments in English Language Teaching (ELT) in the 15 countries or education systems, while Part 3 attempts some generalizations on the teaching of English in East Asia with regard to issues and problems. One of these issues is concerned with the suitability of certain imported teaching techniques in settings where English is seldom used outside the classroom. Some of the problems are conceptualized as dilemmas.
