Split-attention and redundancy effects on mobile learning in physical environments

This study investigated split-attention and redundancy effects in a mobile learning environment on leaf morphology of plants as a function of different combinations of media. Eighty-one fifth-grade students were randomly assigned to the following three conditions: texts with pictures embedded in the mobile device (TP condition); texts embedded in the mobile device and real objects that are outside of the mobile device (TO condition); and texts with pictures embedded in the mobile device and real objects that are outside of the mobile device (TPO condition). Differences in performance on comprehension tests and learning efficiency were examined across conditions. The TP condition was expected to perform better than the TO condition due to a split-attention effect. The TP and TO conditions were expected to perform better than the TPO condition due to a redundancy effect. The results indicated no difference between the TP and the TO condition in comprehension and learning efficiency, but the TP and TO conditions performed better than the TPO condition on both measures. The implications of the results for research and design of mobile learning environments are discussed.     

An experience of teaching for learning by observation: Remote-controlled experiments on electrical circuits

In order to facilitate senior primary school students in Hong Kong to engage in learning by observation of the phenomena related to electrical circuits, a design of a specific courseware system, of which the interactive human–machine interface was created with the use of an open-source software called the LabVNC, for conducting online remote-controlled experiments was developed in this study. The statistically significant results of a pre-test–post-test evaluation study showed that the LabVNC-based system has potential to promote students to learn the target topic under the approach of learning by observation. The assertion of the teacher on the pedagogical value of the remote-controlled experimentation and the enthusiasm of students in using the LabVNC-based system reveal the potential to integrate the use of the LabVNC-based system with the practice of scientific experiments. Based on the feedback from the teacher and students, the existing LabVNC-based system will be refined under the design-based research approach.     

A formative assessment-based mobile learning approach to improving the learning attitudes and achievements of students

The advancement of mobile and wireless communication technologies has encouraged an increasing number of studies concerning mobile learning, in which students are able to learn via mobile devices without being limited by space and time; in particular, the students can be situated in a real-world scenario associated with the learning content. Although such an approach seems interesting to the students, researchers have emphasized the need for well-designed learning support in order to improve the students’ learning achievements. Therefore, it has become an important issue to develop methodologies or tools to assist the students to learn in a mobile learning environment. Based on this perspective, this study proposes a formative assessment-based approach for improving the learning achievements of students in a mobile learning environment. A mobile learning environment has been developed based on this approach, and an experiment on a local culture course has been conducted in southern Taiwan to evaluate its effectiveness. The experimental results show that the proposed approach not only promotes the students’ learning interest and attitude, but also improves their learning achievement.     

Effects of an integrated concept mapping and web-based problem-solving approach on students' learning achievements,perceptions and cognitive loads

Although students could effectively search for web data with proper keywords and select web pages related to the studied core issue, however summarizing or organizing the retrieved information remains a difficult task for them. Concept mapping is known to be an effective knowledge construction tool for helping learners organize important concepts related to a core issue. To address the problem, an integrated concept mapping and web-based problem-solving environment, CM-Quest, has been developed; moreover, an experiment has been conducted to evaluate the effectiveness of the approach on students' learning performance, learning satisfaction and cognitive load in an elementary school social studies course. The results show that the concept map-integrated approach can significantly enhance the students' web-based problem-solving performance, although the students showed lower degrees of technology acceptance and learning satisfaction in comparison with the conventional web-based problem-solving approach. Moreover, it is found that the students in the concept mapping group revealed higher cognitive loads than those in the control group, which could be the factor contributing to the lower technology acceptance degree and learning satisfaction. As a consequence, it is concluded that the integrated concept mapping and web-based problem-solving approach is helpful to students in guiding them to learn in a more effective way. On the other hand, it remains an open issue to find a suitable way of integrating concept maps into the learning process without introducing too much extra cognitive load so as to promote students' acceptance degree of using technology for better learning.     

Integrating intuitive and novel grounded concepts in a dynamic geometry learning environment

The development of geometry knowledge requires integration of intuitive and novel concepts. While instruction may take many representational forms we argue that grounding novel information in perception and action systems in the context of challenging activities will promote deeper learning. To facilitate learning we introduce a grounded integration pattern of instruction, focusing on (1) eliciting intuitive concepts, (2) introducing novel grounding metaphors, and (3) embedding challenges to promote distinguishing between ideas. To investigate this pattern we compared elementary school children in two conditions who engaged in variations of a computer-based dynamic geometry learning environment that was intended to elicit intuitive concepts of shapes. In the grounded integration condition children performed a procedure of explicitly identifying defining features of shapes (e.g. right angles) with the assistance of animated depictions of spatially-meaningful gestures (e.g. hands forming right angles). In a numerical integration condition children identified defining features with the assistance of a numerical representation. Children in the grounded integration were more likely to accurately identify target shapes in a posttest identification task. We discuss the relevancy of the grounded integration pattern on the development of instructional tools.     

Exploring relations among college students’ prior knowledge,implicit theories of intelligence,and self-regulated learning in a hypermedia environment

Researchers and educators continue to explore how to assist students in the acquisition of conceptual understanding of complex science topics. While hypermedia learning environments (HLEs) afford unique opportunities to display multiple representations of these often abstract topics, students who do not engage in self-regulated learning (SRL) with HLEs often fail to achieve conceptual understanding. There is a lack of research regarding how student characteristics, such as prior knowledge and students’ implicit theory of intelligence (ITI), interact with SRL to influence academic performance. In this study, structural equation modeling was used to investigate these issues. It was found that prior knowledge and ITI were related to SRL and performance, and that SRL acted as a benevolent moderator, enhancing the positive effects of prior knowledge upon learning, and diminishing the negative effects of having a maladaptive ITI.     

Effects of teaching and learning styles on students’ reflection levels for ubiquitous learning

Ubiquitous learning (u-learning), in conjunction with supports from the digital world, is recognized as an effective approach for situating students in real-world learning environments. Earlier studies concerning u-learning have mainly focused on investigating the learning attitudes and learning achievements of students, while the causations such as learning style and teaching style were usually ignored. This study aims to investigate the effects of teaching styles and learning styles on reflection levels of students within the context of u-learning. In particular, we investigated the teaching styles at the dimensions of brainstorming and instruction and recall and the learning styles at the dimensions of active and reflective learning. The experiment was conducted with 39 fifth grader students at an elementary school in southern Taiwan. A u-learning environment was established at a butterfly ecology garden to conduct experiments for natural science courses. The experimental results of one-way ANCOVA show that those students who received a matching teaching–learning style presented a significant improvement in their reflection level. That is, matching the learning styles of students with the appropriate teaching styles can significantly improve students’ reflection levels in a u-learning environment.     

Exploring problem solving patterns and their impact on learning achievement in a blended learning environment

Blended learning, thoughtfully combining the best elements of online and face-to-face education, is likely to emerge as the predominant teaching model of the future. In this paper, we present a blended learning environment combining mobile learning, web-based learning, and classroom teaching to provide realistic, practical opportunities for learners and teachers to engage in problem solving activities. The purpose of this study was to explore problem solving patterns and their impact on learning achievement in a blended learning environment. Through quasi-experimental instruction, we collected all of the data of the learning processes from 34 students in a blended learning environment using classroom instruction, mobile and web scenarios. By combining cluster analysis and content analysis, we were able to identify three groups with distinct characteristics: the hybrid-oriented group, the technology-oriented group, and the efficiency-oriented group. Learners in the hybrid-oriented group used the classroom, mobile and web scenario almost equally. They displayed a regular manner in following the instructor’s teaching procedure, and tended to passively accept whatever the teacher said. Students in the technology-oriented group spent most of their time using mobile and web technologies but they revealed superficial problem solving abilities such as a lack of understanding and planning. The efficiency-oriented group was characterized by the efficient monitoring of learning processes. It was more task-oriented and performed better than the other two groups.     

An auto-scoring mechanism for evaluating problem-solving ability in a web-based learning environment

The rapid development of computer and network technologies has attracted researchers to investigate strategies for and the effects of applying information technologies in learning activities; simultaneously, learning environments have been developed to record the learning portfolios of students seeking web information for problem-solving. Although previous research has demonstrated the benefits of applying information technologies to learning activities, the difficulties in doing so have also been revealed. One of the major difficulties is the lack of a mechanism to assist teachers in evaluating the problem-solving ability of the students, such that constructive suggestions can be given to the students, and tutoring strategies can be improved accordingly.     

Embedding game-based problem-solving phase into problem-posing system for mathematics learning

A problem-posing system is developed with four phases including posing problem, planning, solving problem, and looking back, in which the “solving problem” phase is implemented by game-scenarios. The system supports elementary students in the process of problem-posing, allowing them to fully engage in mathematical activities. In total, 92 fifth graders from four different classes were recruited. The experimental group used the problem-posing system, whereas the control group followed the traditional paper-based approach. The study investigates the effects of the problem-posing system on students’ problem-posing ability, problem-solving ability, and flow experiences. The results revealed more flow experiences, and higher problem-solving and problem-posing abilities in the experimental group.     

A concept map-embedded educational computer game for improving students' learning performance in natural science courses

Many recent studies have reported the benefits of educational computer games in promoting students' learning motivations. On the other hand, however, the effect of digital game-based learning in improving students' learning performance has been questioned. Several previous studies have reported that without properly integrating learning strategies into gaming scenarios, the effectiveness of educational computer games could be limited, or may be even worse than that of the conventional technology-enhanced learning approach. In this study, a concept map-embedded gaming approach is proposed for developing educational computer games by integrating concept mapping as part of the gaming scenarios to help students organize what they have learned during the game-based learning process. Moreover, a role-playing game has been developed for an elementary school natural science course based on the proposed approach. From the experimental results, it is found that the concept map-embedded gaming approach can significantly improve the students' learning achievement and decrease their cognitive load. Moreover, the students who learned with the proposed approach revealed a significantly higher degree of perceived usefulness than those who learned with the conventional game-based learning approach.     

A hybrid approach to promoting students’ web-based problem-solving competence and learning attitude

Fostering problem-solving abilities has long been recognized as an important issue in education; however, past studies have shown that it is difficult and challenging to find effective learning strategies or tools for improving students’ problem-solving abilities. To cope with this problem, in this study, a hybrid approach that integrates the cognitive apprenticeship model with the collaborative learning strategy is proposed for conducting web-based problem-solving activities. Students’ problem-solving performance is examined in such a hybrid learning context. Furthermore, past studies indicate that cognitive load could affect learners’ performance; thus, the influence of cognitive load on students’ problem-solving effectiveness with this new approach is investigated in depth. The experimental results show that middle- and low-achievement students in the experimental group gained significant benefits from the hybrid approach in comparison with those who learned with the traditional approach. Accordingly, a discussion of how to accommodate the needs of different learning ability groups is provided.     

An experience of a three-year study on the development of critical thinking skills in flipped secondary classrooms with pedagogical and technological support

The aim of this study was attempting to investigate the outcome of critical thinking achievement of learners when its development is infused into subject teaching with pedagogical and technological support. A total of 124 junior secondary students participated in the three-year trial teaching in Integrated Humanities subject. Flipped classroom strategy was implemented to engage learners in online pre-lesson learning preparation, in-class group discussion inside digital classroom and after-class extended learning using social learning platform. The critical thinking tests found that the students had good performance in the tasks on hypothesis identification, induction and deduction; and some achievements in the tasks on explanation and evaluation. It was found that students needed more time to develop capacities of deduction, explanation and evaluation. The semi-structured interviews found that the teachers and students valued the pedagogical way of providing guidance for students' group sharing for fostering critical thinking skills development. Three implications are discussed to shed light on the infusion of critical thinking skills development into the process of domain knowledge learning, the deployment of appropriate pedagogy to mobilize learners to engage in learning process, and the use of appropriate technology to facilitate learning process inside and outside of classroom.     

Pedagogical approaches for technology-integrated science teaching

The two separate projects described have examined how teachers exploit computer-based technologies in supporting learning of science at secondary level. This paper examines how pedagogical approaches associated with these technological tools are adapted to both the cognitive and structuring resources available in the classroom setting. Four teachers participated in the first study, undertaken as part of the InterActive Education project in Bristol; all of them used multimedia simulations in their lessons. The second study presented was part of the wider SET-IT project in Cambridge; 11 teachers in eight schools were observed using multimedia simulations, data logging tools and interactive whiteboards. Teachers were interviewed in all cases to elicit their pedagogical thinking about their classroom use of ICT.     

A prompt-based annotation approach to conducting mobile learning activities for architecture design courses

In this study, a prompt-based annotation approach is proposed for developing mobile learning systems for architecture design courses. To evaluate the effectiveness of the proposed approach, an experiment was conducted by assigning 56 freshmen randomly to an experimental group and a control group. The students in the experimental group adopted the mobile learning approach with a prompt-based annotation strategy, while those in the control group learned with the conventional in-field instruction and annotations. From the experimental results, it was found that the proposed prompt-based annotation strategy not only promoted the students' self-efficacy, but also improved their learning achievements. In the meantime, it is interesting to find that the experimental group students had medium cognitive load during the field trip, while the control group had rather low cognitive load. This implies that the prompt-based annotation approach engaged the students in mobile learning tasks with reasonable challenges and efforts.     

Key instructional design issues in a cellular phone-based mobile learning project

Adding flexibility to the learning process, mobile learning offers great opportunities for education, especially for teenagers, who show great attentiveness to mobile technologies. Thus, the need to focus on design aspects of such learning is growing. This study aims to reveal critical issues in designing mobile learning based on a program for 11th graders and to unfold students’ perceptions about reasons for participation, satisfaction, implementation processes, and specific content representation types. Reflections on insights gleaned from the instructional design process of the project and students’ perceptions are presented with related recommendations.     

Effectiveness of a Mobile Plant Learning System in a science curriculum in Taiwanese elementary education

This study developed a Mobile Plant Learning System (MPLS) that provides instructors with the ways and means to facilitate student learning in an elementary-school-level botany course. The MPLS represented in this study was implemented to address problems that arise with the use of a didactic approach to teaching and learning botany, as is typically used in elementary schools in Taiwan. To extend opportunities for learning beyond the classroom, this study used personal digital assistants (PDAs) equipped with the MPLS, which provided both teachers and students access to plant information while in the field. A quasi-experimental research design was used to investigate the effectiveness of using the MPLS to support student learning. The responses to questionnaires and interviews indicate that students valued the outdoor learning activities made possible by use of the PDA and its functions. Pre- and post-test results demonstrated that students also benefitted academically from the use of the MPLS and the PDA.     

Using synchronous peer tutoring system to promote elementary students’ learning in mathematics

The face-to-face computer-supported collaborative learning has emerged as an important strategy to elementary students' learning. Few studies have explicitly incorporated the structured peer tutoring to the synchronous environment in mathematics. This study was aimed to explore the effects of the synchronous peer tutoring system on children's mathematics learning. In the project, there were 88 10-11-year-old students who peer tutored each other in mathematics in the face-to-face online environment for a year. Compared to the control group, students in the experimental group had significant gains in mathematics learning, especially in the arithmetic and application types of questions. This study demonstrated the positive effects of peer support via the online synchronous learning on students' self-concept and attitudes toward mathematics learning. The results indicated that the longer the vulnerable pupils engaged in peer tutoring online, the more they benefited from the process. The finding suggests that students demonstrate different mathematics reasoning skills when they are paired with peers at different levels of ability. These findings demonstrate that the synchronous peer tutoring system is an effective tool to enhance elementary students' learning in mathematics, as well as promote positive self-concepts.     

A comparative analysis of the effects of computer and paper-based personalization on student achievement

The aim of this study is to investigate whether personalization of mathematical word problems affects student achievement; and if it does, to find out whether the outcomes vary depending on computer and class environment in the teaching of mathematics. The sample of the research, conducted in the 2006–2007 fall semester, consists of 90 seventh grade in four sub-groups. During the application in the classroom, paper-based personalized and paper-based non-personalized problems were given. As to the computer environment, web-based personalized and web-based non-personalized problems were presented. After the application, an achievement test was performed as an achievement post-test parallel to the pre-test. The results show no significant difference between the scores of the groups who used personalized materials and the groups who used non-personalized materials. The results also indicate that no significant difference exists between those who studied in the computer-based environment and those in the paper-based environment.
