Interaction Devices and Web Design for Novice Older Users

ABSTRACT

This study investigated the effects of interaction devices on the Internet performance of novice older users, and ways to provide appropriate voice assistance to enhance browsing and searching performance of such users. Three experiments were designed and conducted to test three hypotheses. The results indicated that touch screen and handwriting recognition are better than mouse and keyboard in browsing time in the third trial. Touch screen was also found to be better in terms of performance time for keyword search tasks than mouse and voice input in the second trial, and is better in terms of user error for keyword search tasks than mouse and voice input in the first trial. Learning effects were found for using touch screen and handwriting recognition, and mouse and keyboard for browsing and searching tasks. Furthermore, voice-menu assistance was associated with higher satisfaction for browsing tasks.     

Evaluation of a Community-Based Aging Intervention Program

This study evaluated the outcome and process of a community-based aging intervention program for the elderly in Taiwan. The program included education on nutrition and dietary behavior and on physical activities. Outcome and process evaluations were conducted. The program may have had some effects on decreasing some dietary behavioral problems and increasing regular exercise, but the effect on health outcome was not proved. The strength of this program was its proper design, dosage, and implementation; the weaknesses included a low participation rate, low commitment and continuity, and selection bias for the nonparticipants who might be frailer than the actual participants.     

Physical Self-Concept,Possible Selves,and Well-Being Among Older Adults in Taiwan

Possible selves is an important self-related construct for older adults' health behaviors and well-being. This study examines the relationships among older adults' current physical self-concept, possible selves, and physical activity participation, and it examines the mediating effect of possible selves on the relationships between physical self-concept and well-being. One hundred and sixty-three community-dwelling older adults (M _age = 70.91, SD = 6.39) in Taiwan completed the survey packet assessing physical self concept, possible selves, health-related qualities of life, and life satisfaction. Bivariate correlation analyses showed that older adults' possible selves were positively related to physical self-concept and moderate physical activity participation. In addition, the link between older adults' physical self-concept and psychological well-being was mediated partially by possible selves. The results show the significance of using the construct of possible selves to examine and promote older adults' physical activity/exercise behaviors and psychological well-being.     

Help-seeking behaviour of student teachers

Background

Student teachers struggle with a wide range of problems because they are lacking professional knowledge, inexperienced in dealing with colleagues and students, and unfamiliar with school environments. It is essential for the survival of student teachers to establish supportive relationships for professional and personal help. Traditional support mechanisms for student teachers, such as cooperating teachers and university supervising teachers, often fail to provide the needed help. Analysing student teachers' help-seeking behaviour provides an avenue to explore the support they received.

Purpose

The study investigates how student teachers seek assistance. Using a Help-seeking behaviour questionnaire, student teachers' critical problems and their efforts to find assistance are examined.

Sample

The participants were 40 student teachers in a secondary education teacher certificate programme at a university in Taipei, Taiwan. The participants belonged to a class of about 100 student teachers who did their internships at local junior and senior high schools. The participants were teaching in eight subjects, and about two-thirds were female. Every student teacher was assigned a supervising teacher from the university and a cooperating teacher at the placement school.

Design and methods

The questionnaire asked the student teachers to pick a critical problem that they had encountered during the previous week. They were asked to describe the problem, whom they asked for help, how many times and through which communication channel the help was provided. The questionnaire was administered during March and May 2001. Critical problems were sorted into categories. Frequencies and percentages of the help-seeking instances were accumulated for different people and problem categories.

Results

Some student teachers requested help many times; others made a limited number of requests. The number of requests ranged from 1 to 38 per problem, with an average of 12 requests per problem. Among the requests for help (n = 935), only 2% were directed to university supervisors. The student teachers sought help from the cooperating teacher 15% of the time, and 41% of the time they asked student teacher peers for assistance. About 90% of the communication was face to face, 9% was by phone and 1% was by email. The largest number of requests dealt with problems of individual students (19%). The second and third largest problem categories were administration and policy issues (16%) and lack of spare time (15%).

Conclusions

Peer support should be cultivated in teacher training programmes because peer student teachers' help was most frequently sought. Cooperating teachers and university supervising teachers' communication with student teachers can be improved. Various ways of contacting student teachers can be encouraged, but face-to-face communication must still be supported. It is important to keep finding new ways to assess the effectiveness of student teacher support. The results of the Help-seeking behaviour questionnaire can be used to examine the impact of programmes to improve student teaching.     

A tool for changing the world: possibilities of cultural‐historical activity theory to reinvigorate science education

Cultural‐historical activity theory, an outcrop of socio‐psychological approaches toward human development, has enjoyed tremendous growth over the past two decades but has yet to be appropriated into science education to any large extent. In part, the difficulties Western scholars have had in adopting this framework arise from its ontology, which is materialist dialectical and, hence, does not allow easy absorption into non‐dialectical (classical logical) thinking underlying much of Western scholarship. Cultural‐historical activity theory has tremendous potential because it sublates traditional dichotomies in everyday teaching‐learning situations including individual/collective, body/mind, intra‐/inter‐psychological, cognitive/emotive and psychological/sociological. In this contribution, we not only review the existing literature that uses or develops this non‐dualistic approach, but also articulate an intelligible explication of the theory that is more accessible to Western scholars and describe possible future curriculum work and research in science education as an expression of the fruitfulness of the theory.     

Learning with Web Tools, Simulations, and Other Technologies in Science Classrooms

This position paper proposes the enhancement of teacher and student learning in science classrooms by tapping the enormous potential of information communication and technologies (ICTs) as cognitive tools for engaging students in scientific inquiry. This paper serves to challenge teacher-held assumptions about students learning science ‘from technology’ with a framework and examples of students learning science ‘with technology’. Whereas a high percentage of students are finding their way in using ICTs outside of school, for the most part they currently are not doing so inside of school in ways that they find meaningful and relevant to their lives. Instead, the pedagogical approaches that are most often experienced are out-of-step with how students use ICTs outside of schools and are not supportive of learning framed by constructivism. Here we describe a theoretical and pedagogical foundation for better connecting the two worlds of students’ lives: life in school and life outside of school. This position paper is in response to the changing landscape of students’ lives. The position is transformative in nature because it proposes the use of cyber-enabled resources for cultivating and leveraging students new literacy skills by learning ‘with technology’ to enhance science learning.     

Factors Affecting Retirement Attitude among Elementary School Teachers

This study investigated the relationships of teacher efficacy, perceived organizational control, and the teacher-student age gap with teachers’ retirement attitudes. Stratified random sampling was adopted to collect survey responses. A total of 498 valid surveys from 33 elementary schools were collected. Correlational analyses revealed significant positive correlations of efficacy for classroom management (teacher efficacy subdomain), efficacy for student engagement (teacher efficacy subdomain), efficacy for instructional strategies (teacher efficacy subdomain), and the teacher-student age gap with three subdomains of teacher retirement attitude. In addition, there were significant positive correlations of efficacy for instructional strategies and perceived organizational control with the cognitive and behavior subdomains of retirement attitude. Hierarchical regression analysis revealed that efficacy for classroom management can positively predict the affective and cognitive subdomains of retirement attitude. Perceived organizational control can positively predict retirement attitude and its cognitive and behavior subdomains. Finally, the teacher-student age gap can predict retirement attitude and all its subdomains. Discussion of the results and recommendations for future research are provided.     

A Vocabulary Learning Tool for L2 Undergraduates Reading Science and Technology Textbooks

Students of English as a second language who major in science and technology use English-language textbooks to ensure that they can read English materials upon graduation. Research indicates that teachers spend little time helping these students on the linguistic complexity of such textbooks. Vocabulary, grammar, and article structure are elements of this complexity, but to many students, these elements can be akin to locked doors. This study presents MyVLS-Reader, which focuses on unlocking the first of these doors—vocabulary—while assisting in reading. With explicit vocabulary learning, students learn and memorize individual vocabulary, but the context is lost if the depth of learning discards context. In implicit vocabulary learning, students acquire vocabulary through repeated exposure to contexts, but repeated encounters with new words are required. Few e-learning systems combine both vocabulary-learning approaches. MyVLS-Reader achieves such synergy by (1) using a keyword setting to provide context-matched vocabulary explanation while reading and (2) embedding multiple learning choices, such as keyword setting, the review and memorization of explicit vocabulary, and the option to ask instructors. This study includes two rounds of evaluations: (1) an evaluation of the learning achievements of control and treatment groups and (2) a quantitative and qualitative investigation of perceptions regarding the use of MyVLS-Reader. The evaluation results indicate that the treatment group developed a better vocabulary than the control group in significantly less time. The use of MyVLS-Reader also slightly improved higher-order thinking skills. This result suggests that MyVLS-Reader can effective assist students in building their vocabulary while reading.     

Collaborative Action Research on Technology Integration for Science Learning

This paper briefly reports the outcomes of an action research inquiry on the use of blogs, MS PowerPoint [PPT], and the Internet as learning tools with a science class of sixth graders for project-based learning. Multiple sources of data were essential to triangulate the key findings articulated in this paper. Corresponding to previous studies, the incorporation of technology and project-based learning could motivate students in self-directed exploration. The students were excited about the autonomy over what to learn and the use of PPT to express what they learned. Differing from previous studies, the findings pointed to the lack information literacy among students. The students lacked information evaluation skills, note-taking and information synthesis. All these findings imply the importance of teaching students about information literacy and visual literacy when introducing information technology into the classroom. The authors suggest that further research should focus on how to break the culture of “copy-and-paste” by teaching the skills of note-taking and synthesis through inquiry projects for science learning. Also, further research on teacher professional development should focus on using collaboration action research as a framework for re-designing graduate courses for science teachers in order to enhance classroom technology integration.
