Elementary school–wide implementation of a blended learning program for reading intervention

The authors examined the implementation of a blended learning program for literacy instruction across kindergarten through Grade 5 in a Title I urban elementary school, including a population of students (18%) who are English learners. Student progress in the online component of the blended learning program was a significant predictor of growth in reading performance on a standardized reading assessment (Group Reading Assessment and Diagnostic Evaluation, Pearson Assessment, Boulder, CO) when controlling for student grade level, initial student skill level, and English learner status; however, students in kindergarten through Grade 2 showed more substantial gains than students in later grades. These results suggest there is a benefit of a blended learning approach to literacy instruction for a diverse cross-section of students, particularly when beginning instruction in the early grades.     

Effects of concept-mapping-based interactive e-books on active and reflective-style students’ learning performances in junior high school law courses

Researchers have pointed out that interactive e-books have rich content and interactive features which can promote students’ learning interest. However, researchers have also indicated the need to integrate effective learning supports or tools to help students organize what they have learned so as to increase their learning performance, in particular, for abstract and complex learning content such as that in law courses. In this study, a concept-mapping-based interactive e-book learning mode was proposed. To understand the learning effects, a quasi-experimental design was used to compare the learning achievement and motivation of the students learning with the proposed approach (experimental group) and those learning with conventional interactive e-books (control group) in a junior high school fundamental law course. Meanwhile, the learning achievement and motivation of the students with different learning styles were also explored. The experimental results showed that the proposed approach significantly improved the students’ learning achievement, especially for the active-style students; moreover, it was found that the lead-in of concept mapping did not affect the students’ learning motivation. Factors that might affect the students’ learning achievement and motivation with the concept-mapping-based interactive e-book approach are discussed accordingly.     

Enhancing students’ choreography and reflection in university dance courses: A mobile technology-assisted peer assessment approach

Choreography is an important and challenging educational objective in dance courses. However, most previous technology-enhanced learning studies for dance education mainly focused on students’ dance skills, while the issue concerning the approaches to promoting students’ choreographic performance has generally been ignored. To address this issue, the present study developed a mobile technology-assisted peer assessment approach based on social constructivism for use in a university general education dance routine choreography class. A total of 266 university students were divided into an experimental group and a control group. The experiment lasted for 15 weeks and involved two rounds of peer assessment. The results showed that mobile peer assessment could significantly enhance the innovative competence of dance routines and dance skills. In addition, according to the students’ feedback, the dance routine choreography class was conducive to improving social skills, innovative competence, and intrinsic motivation, while mobile peer assessment could assist students in understanding accurate evaluation criteria, reflecting on their own in a more objective way, and broadening the aspects of appreciating the work.     

Playfulness-based design in educational games: a perspective on an evolutionary contest game

Playfulness steering is an emerging approach in educational game design and play. The integration of arithmetical computation, game strategy, and teamwork into one game allows players to interactively “steer” the playfulness and enhance learning. In this paper an evolutionary contest game was designed and implemented to examine the influencial factors. Using action research, focus groups and hermeneutic methods, this study suggest that the playfulness design of an evolutionary game is influenced by the degree of uncertainty and flexibility in decision-making, the level of challenge, equal conditions for fair play, opportunities to compete/cooperate, and the level of interactivity.     

Effects of the inquiry-based mobile learning model on the cognitive load and learning achievement of students

The advancement of mobile device and wireless communication technologies is having a great influence on the design concept of learning activities. In this study, we attempt to integrate field study into the inquiry-based mobile learning model; moreover, a mobile learning environment that allows students to access both physical and virtual resources is developed accordingly. During the in-field learning activity, the mobile learning system is able to present the learning tasks, guide the students to visit the real-world learning targets for exploration, and provide them with supplementary materials via the mobile devices. The aim of this research focuses on the effects of this mobile learning model on students' cognitive load and learning achievements. The 51 sixth graders who participated in this research were assigned to an experimental and a control group. From the pre and posttests as well as the cognitive load questionnaire, it was found that the students who learned with the inquiry-based mobile learning approach had better learning achievement and less cognitive load than those who learned with the traditional approach. Therefore, it is concluded that the mobile learning model has positive effects on elementary students in local culture learning.     

A case study of collaboration with multi-robots and its effect on children's interaction

Learning how to carry out collaborative tasks is critical to the development of a student's capacity for social interaction. In this study, a multi-robot system was designed for students. In three different scenarios, students controlled robots in order to move dice; we then examined their collaborative strategies and their behavioral interactions. The following three scenarios were used: three students to three robots, three students to two robots, and two students to three robots. The experimental samples comprised sixth-grade students in elementary schools, 16 groups in total, and each group comprised three students. The results revealed three collaborative strategies for solving problems that emerged from the three scenarios: (1) independent-control (like cooperation), (2) mutual-control (like collaboration), and (3) coordinator-directed (like collaboration with coordinator). This study also found that students completed a task better with the least required time when they adopted the mutual-control strategy. In addition, coordination in the mutual-control and coordinator-directed strategies was generally regarded as helpful to task completion. With respect to behavioral interactions, students understood the importance of coordination yet still recognized that the skill of negotiation had to be learned. Our results suggest that the mutual-control and coordinator-directed collaborative strategy increased the frequency of task related interactions. Because collaboration inevitably entails conflicts, we should guide students not only in preventing these conflicts but also in learning how to cope with conflict and communicate and coordinate with others. By working together, learners had to figure out how to reduce conflicts, which was both a benefit to the completion of their collaborative tasks and an important skill for their socialization.     

Developing digital portfolios: investigating how digital portfolios can facilitate pupil talk about learning

The Digital Portfolio Project at Newcastle University aimed over one year (2002/2003) to support teachers in producing, storing and accessing assessment portfolios of learner’s work using information and communications technology (ICT). This paper draws on evidence of pupil views collected as part of 14 teacher‐led case studies. The teachers all approached the task of developing digital portfolios in different ways and the variety of end products was large; however, the common result was the value placed on using the portfolio as a tool for reflection and celebration of children’s learning. As part of the data collection teachers were encouraged to gather pupil views about the digital portfolio learning process. These comments provide an interesting and surprisingly analytical perspective of the research and learning process not commonly considered in the academic community. This paper documents the pupils’ views and uses them to review the strength of the digital portfolio process and the benefits of using it in the primary classroom.     

Structural change in search engine news service: a social network perspective

This research investigates structural change made by Naver's online news section and how it has impacted the overall traffic flow of Korea's online news. This paper examined 45 websites in 2008 and 2010, and the total number of pages viewed within these sites was considered in the analysis. Social network analysis was applied to study the relationships between the news sites. The analysis through degree centrality and Bonacich powers shows that there has been a shift in market leadership. In 2007, Naver, the top search engine in Korea, stepped down from its leading position after they started to provide news services. Daum, the second largest search engine, has taken over the central position as the most influential news site. Based on the results of this study, practical implications for online service markets and theoretical implications for online services are recommended accordingly.

Why might relative fit indices differ between estimators?

Previous research indicates that relative fit indices in structural equation modeling may vary across estimation methods. Sugawara and MacCallum (1993) explained that the discrepancy arises from difference in the function values for the null model with no further derivation given. In this study, we derive explicit solutions for parameters of the null model. The null model specifies the variances of the observed variables as model parameters and fixes all the covariances to be zero. Three methods of estimation are considered: the maximum likelihood (ML) method, the ordinary least squares (OLS) method, and the generalized least squares (GLS) method. Results indicate that ML and LS yield an identical estimator, which is different from GLS. Function values and associated chi‐square statistics of the null model vary across estimation methods. Consequently, relative fit indices using the null model as the reference point in computation may yield different results depending on the estimation method chosen. An illustration example is given and implications of this study are discussed.
