Many studies have shown that learners’ sustained attention strongly affects e-learning performance, particularly during online synchronous instruction. This work thus develops a novel attention monitoring and alarm mechanism (AMAM) based on brainwave signals to improve learning performance via monitoring the attention state of individual learners and helping online instructors or teaching assistants to improve the sustained attention levels of learners with low-attention states as they perform online synchronous instruction activities. Totally, 83 and 65 Grade 7 students were randomly assigned to the experimental and control groups that respectively underwent online synchronous instruction with and without AMAM support. Analytical results reveal that the experimental group of learners exhibited significantly better learning performance and sustained attention than those in the control group, verifying that the AMAM efficiently promotes the learning performance and sustained attention of learners. Moreover, the proposed AMAM was more helpful in improving the learning performance of female learners than those of male learners and improved the sustained attention of both male and female learners. Furthermore, the sustained attention, frequency of attention alarms, and learning performance of the learners in the experimental group were strongly correlated, and the sustained attention and frequency of attention alarms strongly predicted learning performance. 相似文献

In order to promote scientific inquiry in secondary schooling in Taiwan, the study developed a computer-based inquiry curriculum (including structured and guided inquiry units) and investigated how the curriculum influenced students’ science learning. The curriculum was implemented in 5 junior secondary schools in the context of a weeklong summer science course with 117 students. We first used a multi-level assessment approach to evaluate the students’ learning outcomes with the curriculum. Then, a path analysis approach was adopted for investigating at different assessment levels how the curriculum as a whole and how different types of inquiry units affected the students’ development of conceptual understandings and inquiry abilities. The results showed that the curriculum was effective in enhancing the students’ conceptual knowledge and inquiry abilities in the contexts of the six scientific topics. After the curriculum, they were able to construct interconnected scientific knowledge. The path diagrams suggested that, due to different instructional designs, the structured and guided inquiry units appeared to support the students’ learning of the topics in different ways. More importantly, they demonstrated graphically how the learning of content knowledge and inquiry ability mutually influenced one another and were reciprocally developed in a computer-based inquiry learning environment. 相似文献

Oral reading fluency is an indicator of overall reading competence. Many studies have claimed that repeated reading can promote oral reading fluency. Currently, novel Web- or computer-based reading technologies offer interactive digital materials that promote English oral reading fluency using the repeated reading strategy; however, paper-based English materials in physical classrooms are still used to train students in oral reading fluency because most students are used to learning environments with paper, pen, and face-to-face interaction. With the growth of digital pen technologies, developing an interactive learning environment that combines printed textbooks and a digital pen to support English-language classroom learning has become feasible. Thus, this work presents a digital pen and paper interaction platform (DPPIP) composed of a student-learning tier, course management tier, and teacher tutoring tier, in which digital pen technologies are integrated with printed textbooks and Moodle course management system, to support the repeated reading strategy for promoting English-language oral reading fluency, learning motivation, and learning satisfaction. Meanwhile, this work also examined whether the proposed DPPIP provides different benefits in terms of the promotion of the oral reading fluency to students with field-dependent and field-independent cognitive styles. Based on the non-equivalent control group design in the quasi-experimental research, this work recruited two junior high school classes from Taoyuan County, Taiwan, to participate in an instructional experiment. One class was randomly assigned to the experimental group, which used the DPPIP to perform the repeated reading strategy in order to enhance English-language oral reading fluency. By contrast, the other class was assigned to the control group, which adopted the traditional paired reading method to support the repeated reading strategy to improve English-language oral reading fluency. Analytical results show that applying the proposed DPPIP to support a regular English-language course in classrooms had significantly positive effects in promoting the English-language oral reading fluency, learning motivation, and learning satisfaction of junior high school students. Moreover, this DPPIP simultaneously helped the experimental group students with the field-independent and field-dependent cognitive styles accelerate their oral reading fluency. Importantly, the oral reading fluency of the experimental group students is positively correlated with the frequency which the digital pen was used. 相似文献

Despite the popularity of mobile reading devices, many studies have indicated that small screens restrict information transmission, adversely affecting reading performance on mobile devices. Moreover, mobile reading typically occurs in different reading contexts. Therefore, suitable text display type for mobile reading in different reading contexts should be considered, such that learners can effectively read content. This work selected the frequently used static and dynamic text display types (i.e. Paging and Auto-scrolling) and assessed their effects on mobile reading performance. Furthermore, the features of static and dynamic text display types were considered when designing a mixed text display type for mobile reading. Based on brainwave detector, reading-comprehension test sheet, and cognitive-load scale, this work designed a mobile reading experiment with a two-factor experimental design to assess the effects of the selected static, dynamic, and designed text display types, which were respectively presented in sitting, standing, and walking contexts, on reading comprehension, sustained attention, and cognitive load of learners. Experimental results show that sitting obtained the highest sustained attention and the mixed text garnered lowest sustained attention. Moreover, although analytical results show that no significant difference existed in overall reading comprehension with each text type presented with the mobile reading contexts, reading comprehension (i.e. memory, comprehension, and application types) was significantly affected by the reading context, and to some degree, the text display type. This work also found that the text display type is a major factor affecting learners' cognitive load; however, learners' cognitive load is not be affected by the considered reading contexts. Among the three text display types, the mixed type generates the highest cognitive load, followed by the dynamic type, and then the static type. In conclusion, the three reading contexts with the three text display types have both advantages and disadvantages for reading comprehension, sustained attention, and cognitive load. As a result, text display type for mobile reading on small screens should be adjusted according to reading context or to improve reading comprehension, attention, or cognitive load. 相似文献

Developing personalised web-based learning systems has been an important research issue in e-learning because no fixed learning pathway will be appropriate for all learners. However, most current web-based learning platforms with personalised curriculum sequencing tend to emphasise the learner preferences and interests in relation to personalised learning services but fail to consider the difficulty level of course materials, learning order of prior and posterior knowledge and learner abilities while constructing a personalised learning path. As a result, these ignored factors thus easily lead to the generation of poor quality learning paths. Generally, learners could generate cognitive overload or fall into cognitive disorientation owing to inappropriate curriculum sequencing during learning processes, thus, reducing the learning effect. With the advancement of artificial intelligence technologies, ontology technologies enable a linguistic infrastructure to represent conceptual relationships between course materials. Ontology can be served as a structured knowledge representation scheme, capable of assisting the construction of a personalised learning path. This study thus proposes a novel genetic-based curriculum sequencing scheme based on a generated ontology-based concept map, which can be automatically constructed by the pretest results of numerous learners, to plan appropriate learning paths for individual learners. The experimental results indicated that the proposed approach could create high-quality learning paths for individual learners. The proposed approach thus can help learners to learn more effectively and to likely reduce learners' cognitive overloads during learning processes. 相似文献

Analyzing learners’ learning behaviors helps teachers understand how learning behaviors of learners influence learning performance. To determine which learning behaviors influence learners’ science-based inquiry learning performance, this work develops an xAPI (Experience Application Programming Interface)-based learning record store module embedded in a Collaborative Web-based Inquiry Science Environment (CWISE) to record detailed data about students’ learning processes. This work discusses whether the significant correlation and cause-effect relationship among science inquiry competence, learning time, and learning performance exist, and examines whether remarkable shifts and differences in the learning behaviors of learners with different learning performances and inquiry competences exist by using sequential pattern mining and lag sequential analysis. The results demonstrate that inquire ability, total learning time in the designed inquiry learning course, and learning time in an inquiry buoyancy simulation experiment are positively correlated with learning performance and can predict learning performance, and the learning time in the inquiry buoyancy simulation experiment appears to be the most significant predictor. The results of lag sequential analyses indicate that learners with high learning performance and high inquiry competence re-adjust hypotheses after performing an inquiry buoyancy simulation experiment, while learners with low learning performance and low inquiry competence lack this critical inquiry learning behavior. This study presents a systematic analysis method to insight the effective learning behaviors in a web-based inquiry learning environment based on mining students’ learning processes, thus providing potential benefits in guiding learners to adjust their learning behaviors and strategies.

Despite rapid and continued adoption of mobile devices, few learning modes integrate with mobile technologies and libraries' environments as innovative learning modes that emphasize the key roles of libraries in facilitating learning. In addition, some education experts have claimed that transmitting knowledge to learners is not the only educational goal, as cultivating problem-solving skills is also essential. By integrating the problem-based learning (PBL) model with book resources in libraries, one can identify the advantages of libraries in supporting e-Learning, resulting in innovative and valuable research. Therefore, this study presents a novel intelligent mobile location-aware book recommendation system (IMLBRS) with map-based guidance to support cooperative PBL in a real-library environment. Using map navigation and book recommendation functionalities, learners can search for books associated with problem-solving with increased ease and efficiency, thereby helping learners increase their PBL performance in a library environment. Experimental results reveal that learning performance during PBL supported by the proposed IMLBRS for book searches is superior to learning performance during PBL supported by the online public access catalogue (OPAC). Experimental results also show that the proposed system facilitates better learning performance for learners with a field-dependent learning style than for learners with a field-independent learning style. Moreover, the proposed system facilitates learner contemplation, cooperative learning, and library user education as learners interact with a real-library environment and peers during cooperative PBL. 相似文献

Many studies have identified web-based cooperative learning as an increasingly popular educational paradigm with potential to increase learner satisfaction and interactions. However, peer-to-peer interaction often suffers barriers owing to a failure to explore useful social interaction information in web-based cooperative learning environments. This easily leads to learners being unable to seek appropriate learning partners for facilitating effective cooperative learning. This problem frequently causes poor learning effectiveness in web-based cooperative learning environments. Generally, instructor assigned or learner selected learning peers cannot ensure to compose suitable learning partners for individual learners in cooperative learning environments. A suitable learning partner can help the learner, who is learning in the personal way and encounters the difficulty, to solve problems. Inappropriate learning partners cannot only easily lead to poor learning interaction and achievement, but can also lead to the meaning of cooperative learning being lost. Although many web-based learning systems have already been developed to assist cooperative learning, supporting peer-to-peer interaction in computer-supported cooperative learning (CSCL) is still immature. As a result, this study presents a novel scheme for recommending appropriate learning partners for individual learners utilizing mining of learning interactive social networks in a cooperative problem-based learning (PBL) environment. Results of this study show that the proposed scheme helps encourage learners to interact with learning peers more actively and positively, and facilitates learning performance in a cooperative PBL environment. 相似文献

Because learning English is extremely popular in non-native English speaking countries, developing modern assisted-learning schemes that facilitate effective English learning is a critical issue in English-language education. Vocabulary learning is vital within English learning because vocabulary comprises the basic building blocks of English sentences. Therefore, numerous studies have attempted to increase the efficiency and performance of learning English vocabulary. ‘The situational learning approach’ proposed that ‘context’ is an important consideration in the language learning process and can enhance learner learning interest and efficiency. Restated, meaningful vocabulary learning occurs only when the learning process is integrated with social, cultural and life contexts. With the rapid development of context-awareness techniques, the development of context-aware mobile learning systems, which can support learners in learning without constraints of time or place via mobile devices and associate learning activities with real learning environment, enables the conduct of a novel context-aware ubiquitous learning mode to enhance English vocabulary learning. Accordingly, this study proposes a personalised context-aware ubiquitous learning system (PCULS) for learning English vocabulary based on learner location as detected by wireless positioning techniques, learning time, individual English vocabulary abilities and leisure time, enabling learners to adapt their learning content to effectively support English vocabulary learning in a school environment. Experimental results indicated that the accuracy of the employed wireless positioning scheme is over 92%, which is sufficient to help learners detect their locations. Additionally, the PCULS has been successfully implemented on PDA devices in a school environment to support effective situational English vocabulary learning. Experimental result indicates that the learning performance of learners who used personalised English vocabulary learning systems with context awareness (i.e. PCULS) was superior to learners who used personalised English vocabulary learning systems without context awareness. 相似文献

With the gradual adoption of multimedia technologies in curriculum designs, the need has increased for in-depth studies that explore how different presentation techniques for multimedia materials affect learner emotions and learner performance. This study employed the emWave system, a stress detector for emotional states that was developed by the Institute of HeartMath for measuring changes in learner emotional states when presented with different multimedia materials with the same learning content. By analyzing the collected emotional data and assessment of learning performance, this study explores how different multimedia learning materials affect learning emotions, and ultimately, learning performance. Preliminary results show that the video-based multimedia material generates the best learning performance and most positive emotion among three types of multimedia materials assessed in the study. Moreover, a partial correlation exists between negative learning emotion and learning performance. This study confirms that simultaneously considering pretest score and negative emotion can predict learning performance of learners who use video-based multimedia material for learning. It also finds significant gender difference in learner emotional states while using different multimedia materials for learning: female learners in this study are more easily affected by different multimedia material than male learners. 相似文献
