Multilingual document mining and navigation using self-organizing maps

One major approach for information finding in the WWW is to navigate through some Web directories and browse them until the goal pages were found. However, such directories are generally constructed manually and may have disadvantages of narrow coverage and inconsistency. Besides, most of existing directories provide only monolingual hierarchies that organized Web pages in terms that a user may not be familiar with. In this work, we will propose an approach that could automatically arrange multilingual Web pages into a multilingual Web directory to break the language barriers in Web navigation. In this approach, a self-organizing map is constructed to train each set of monolingual Web pages and obtain two feature maps, which reveal the relationships among Web pages and thematic keywords, respectively, for such language. We then apply a hierarchy generation process on these maps to obtain the monolingual hierarchy for these Web pages. A hierarchy alignment method is then applied on these monolingual hierarchies to discover the associations between nodes in different hierarchies. Finally, a multilingual Web directory is constructed according to such associations. We applied the proposed approach on a set of Web pages and obtained interesting result that demonstrates the feasibility of our method in multilingual Web navigation.     

“iRobiQ”: the influence of bidirectional interaction on kindergarteners’ reading motivation,literacy, and behavior

This study focused on an intelligent robot which was viewed as a language teaching/learning tool to improve children’s reading ability, reading interest, and learning behavior. The iRobiQ, with its multimedia contents, was employed to encourage children to read, speak, and answer questions. Fifty-seven pre-kindergarteners participated in this study, and they were divided into an experimental group (30 children using iRobiQ) and a control group (27 children using a tablet-PC). After 2 months of experiments, the reading ability of the experimental group was better than that of the control group. It was found that using iRobiQ as a learning tool had many advantages, for example, the enhancement of learners’ reading literacy, in comparison with the use of tablet-PC. In this study, there were three interesting findings: (1) iRobiQ is a more effective learning companion as compared to tablet-PC; (2) iRobiQ is a bidirectional interactive toy; and (3) iRobiQ can foster and promote the peer collaboration and competition because it has intriguing characteristics, particularly its communicative and interactive functions. The bidirectional interactive robots allow pre-kindergarten teachers to create more active and interactive learning environment for children and provide the children with more various learning contents.     

Effects of a dementia dietary educational program on nutritional knowledge and healthy eating behavior of family caregivers

ABSTRACT

Family caregivers play a critical role in dietary care and the nutritional status of people with dementia. The aim of this study was to investigate the effects of a family care-based dementia dietary educational program (DDEP) on family caregivers’ nutritional knowledge, healthy eating behavior and nutritional status of people with dementia. A total of 57 pairs of participants completed this longitudinal experimental study. Group A received routine care. Group B received the DDEP. Three outcomes were measured at pretest (T1), posttest (T2) and follow-up test (T3). Generalized estimating equations and regression were used to analyze the data. The scores of the caregivers’ nutritional knowledge significantly increased after receiving the DDEP in group B, and this increase was better than in group A. The posttest and follow-up test scores of healthy eating behavior were significantly higher than the pretest scores in both groups. The scores of nutritional status in group B increased from the pretest to the follow-up test, although there was no significant difference between the two groups. Some demographic factors played significant roles in the caregivers’ nutritional knowledge and healthy eating behavior. In sum, the DDEP improved the caregivers’ nutritional knowledge and healthy eating behavior for dementia. The demographic factors of family caregivers should be considered when providing nutritional information to enhance the nutritional status of people with dementia. The DHPDEP should be incorporated into the in-service education and training courses for nurses or dietitians who work with people with dementia.     

Science Learning Outcomes in Alignment with Learning Environment Preferences

This study investigated students’ learning environment preferences and compared the relative effectiveness of instructional approaches on students’ learning outcomes in achievement and attitude among 10th grade earth science classes in Taiwan. Data collection instruments include the Earth Science Classroom Learning Environment Inventory and Earth Science Learning Outcomes Inventory. The results showed that most students preferred learning in a classroom environment where student-centered and teacher-centered instructional approaches coexisted over a teacher-centered learning environment. A multivariate analysis of covariance also revealed that the STBIM students’ cognitive achievement and attitude toward earth science were enhanced when the learning environment was congruent with their learning environment preference.     

The development of a questionnaire to measure students' motivation towards science learning

The purpose of this study was to develop a questionnaire that measures students' motivation toward science learning (SMTSL). Six scales were developed: self‐efficacy, active learning strategies, science learning value, performance goal, achievement goal, and learning environment stimulation. In total, 1407 junior high school students from central Taiwan, varying in grades, sex, and achievements, were selected by stratified random sampling to respond to the questionnaire. The Cronbach alpha for the entire questionnaire was 0.89; for each scale, alpha ranged from 0.70 to 0.89. There were significant correlations (p?<?0.01) of the SMTSL questionnaire with students' science attitudes (r?=?0.41), and with the science achievement test in previous and current semesters (r ^p?=?0.40 and r ^c?=?0.41). High motivators and low motivators showed a significant difference (p?<?0.01) on their SMTSL scores. Findings of the study confirmed the validity and reliability of the SMTSL questionnaire. Implications for using the SMTSL questionnaire in research and in class are discussed in the paper.     

High-tech,hard work: an investigation of teachers’ work in the digital age

This paper explores the ways in which digital technologies are now implicated in the work – and specifically the labour – of school teachers. Drawing upon qualitative studies in two Australian high schools, the paper examines the variety of ways in which teachers’ work is now enacted and experienced along digital lines. In particular, the paper highlights the association of digital technologies with the standardization, evidencing, intensification and altered affect of teachers’ work. The paper questions the extent to which these trends might be seen as constituting ‘new’ forms of labour, with the research data pointing to continuities and disjunctures in terms of teachers’ autonomy and professionalization. The paper also considers how these conditions are experienced in different ways across the teaching workforce. The paper concludes by reflecting on how fairer and/or empowering working conditions might be achievable through alternate uses of digital technology.

The Reciprocity of ‘Imitative Learning’ through Apprenticeship

Humans are proposed to have evolved to learn through observation, imitation and practice or mimesis. In this article, the contribution of imitation, as an important but poorly understood aspect of mimetic learning, is advocated to create affordances for dyadic learning. However, learning through imitation is often perceived with negative connotations perhaps framed by viewpoints individuals have derived from experiences of rote learning and repetitive work. Yet, learning through imitation plays a key role in the learning of skills, including many of the non-verbal communicative and tacit aspects of trades work. This article explores the ways trade apprentices learn, with emphasis on the contribution of imitation. Recommendations to improve the reciprocal relationships between mentor and apprentice, initiated and developed through learning by ‘imitation’, are discussed and considered.     

The influence of a gesture-based learning approach on preschoolers’ learning performance,motor skills,and motion behaviors

This study developed a gesture-based learning approach to build a virtual interactive learning environment for preschoolers by combining a gesture-based computing device and a game-based learning model. Using sequential analysis, this study investigated how this approach influenced children’s learning performance, motor skills, and motion behaviors. A quasi-experiment was conducted with 142 kindergarten-level-3 preschoolers. The results showed that the gesture-based learning approach improved the students’ learning performance and motor skills compared with the traditional activity-based learning approach. The main learning pattern showed that the preschoolers controlled their body motion behaviors and movements to learning cognitive knowledge, which achieving a flow state that improved preschoolers’ learning performance and motor skills. In addition, the main motion pattern showed that the preschoolers interacted with the game by coordinating their body movement with the projected human skeleton’s movement, which improved their motor skills.     

Effects of 6E-oriented STEM practical activities in cultivating middle school students’ attitudes toward technology and technological inquiry ability

ABSTRACT

Background: STEM education has become a focus of research and teaching interest in recent years. However, not all scholars agree on the definition and purpose of STEM education. This paper summarizes related past research and suggests that, according to the requirements of Taiwan’s educational environment, STEM education should focus on the cultivation of middle school students’ attitudes toward technology and their ability to engage with technological inquiry.

Purpose: The purpose of this study is to explore the effects of STEM education on attitudes toward technology and technological inquiry abilities of middle school students, this study used the 6E Learning byDeSIGN? model proposed by the International Technology and Engineering Educators Association in the US to design a 6E-oriented STEM practical activity.

Sample: The sample of the study consisted of 139 seventh-grade students from six different classes who participated in a practical activity related to egg protection devices.

Design and methods: To achieve this research purpose, a quasi-experimental design was used, with pre-treatment and post-treatment evaluations of each group. Both the experimental and control groups participated in the activity; however, the experimental group students were guided through the activity using a 6E teaching strategy, whereas the control group students were guided using a problem-solving teaching strategy.

Results: The results showed that a 6E teaching strategy had a positive effect on middle school students’ attitudes toward technology and technological inquiry abilities, but these effects were not statistically different from the effect on the control group with problem-solving teaching strategy.

Conclusions: This study indicates there is no significant advantage in using a 6E process over a problem solving approach. Technology teachers aiming to improve students’ attitudes toward technology and their technological inquiry abilities consider refining the 6E-oriented STEM practical activity process, and students may demonstrate better performance in these two areas.
