Development and evaluation of a context-aware ubiquitous learning environment for astronomy education

In recent years information technology has been integrated into education to produce a series of trends, beginning with “electronic learning” (e-learning), through “mobile learning” (m-learning) and finally to “ubiquitous learning” (u-learning), which aims to improve learner motivation through overcoming the conventional limitations of time and location. U-learning practices are still being developed, and learners frequently experience difficulty focusing on learning objectives, and effective learning strategy tools are still lacking. This study reports the design of a context-aware astronomy learning system. The system integrates several technologies, including radio frequency identification, wireless communication networks, handheld mobile devices, and databases to help students learn astronomical concepts. Two content modules were developed in the context of natural science education for fifth-grade elementary school students in Taiwan. Indicators of user experience with the system were collected for further phenomenographic analysis, based on four perspectives of the Unified Theory of Acceptance and Use of Technology model to assess learner willingness to use this novel u-learning approach. Results show that ease-of-use and the availability of immediate operational or technical support are key factors in increasing learning motivation and performance.     

The Effects of Multimedia Content Design Modalities on Students’ Motivation and Achievement in History

This study examined the effects of different multimedia design modalities on middle-school students’ motivation and achievement in history and also sought to determine whether an interaction effect on achievement occurs between students’ prior knowledge and the different multimedia design modalities. Two groups of eighth-grade students enrolled in a rural middle school in a southern state created multimedia artifacts using two design modalities: video content design and visual content design. Each group consisted of 21 students ranging in age from 13 to 14. Both groups completed a history lesson on state governors and created video content or visual content, respectively. The results showed that students earned significantly higher achievement test scores when they were involved in the visual content design modality. However, no differences were found in each of the four motivation sub-measures. Furthermore, there was no interaction effect between students’ prior knowledge levels and the different content design modalities.     

Modern foreign languages: decision-making,motivation and 14–19 schools

ABSTRACT

This article reports on an exploratory study comparing motivation and student choice in modern foreign language lessons in secondary schools (11–16 or 11–18) and schools for 14–19 year olds in England. The study uses data gathered from 634 Year 10 students (aged 14–15) and uses Self-Determination Theory to compare motivation amongst students in the two types of schools. It finds that student motivation differed significantly in each, with students in 14–19 schools displaying more autonomous motivation. Students in schools in this category were less likely to have been given a choice as to whether or not to take the subject than their peers, suggesting that they may feel autonomous in ways not governed by subject choice. Possible reasons for the differences in motivation in the two kinds of school are discussed and directions for future study proposed.     

Music students’ perception of the use of multi-media technology at the graduate level in hong kong higher education

The core purpose of this paper is to draw together research issues and concrete problems with the use of multimedia technology at the graduate level in higher music education by examining one university’s responses to the challenges posed by the use of multimedia technology as a teaching and learning aid for music education. Between June and July 2006, this study conducted a simple questionnaire and interview survey of 16 postgraduate students. The results suggest that music students are confident in their abilities to use multimedia technologies but that many do not believe that the introduction of multimedia technologies into the curriculum will improve the quality of their education. Whilst students’ motivation to learn depends on their interest in the subject and their lecturer’s approach, the incorporation of technology should always be relevant to each individual module. The results of this case study could help other universities respond to the changes brought about by electronic learning and other educational multimedia technology.     

Investigating the use and effectiveness of diverse types of materials in the delivery and support of lab sessions for multimedia subjects and students

This research study explores the use of different lab material, investigating which types of materials contribute the most to the delivery and support of laboratory (lab) sessions to design, skill‐based and technical courses in higher education in the UK. A qualitative research methodology was employed for this investigation and included both key stakeholders in academia, including 75 students and 12 tutors. An investigation was also conducted tracking student activity on the university's e‐learning facility (U‐link). Our key findings indicate that overall electronic material is considered the most effective type of material for the delivery of a lab session. This is followed by print, video and lastly audio material according to student responses and video, print and audio material according to tutor responses. Student and tutor responses varied per individual module/subject area. Video material was regarded by students and tutors as the most effective type for the delivery of skill‐based lab sessions and generally for independent learning, and electronic material was regarded as the most effective type for the delivery of technical and design lab sessions. Lastly, student tracking revealed that the introduction of video lab material in two modules increased the average time spent by students on U‐link by 58% for the technical module and 97% for the skill‐based module respectively.     

Welche Rolle spielt neben Merkmalen des Instruktionsdesigns die fachspezifische und aufgabenspezifische Motivation beim Lernen mit Multimedia im naturwissenschaftlichen Unterricht?

The present paper reports on an empirical study which investigated learning with text and animations in the science classroom. In a 2?×?2 design the presence of multimedia learning material instruction (text only vs. text + animations) as well as the modality of the explanatory text (spoken vs. written) were tested. Prior to learning, students’ motivation to learn was assessed as a continuous factor. Recall and transfer were assessed immediately after learning. The results show better recall of information for learners with multimedia materials, providing the animations were accompanied by spoken text. However, in contrast to the positive effects of domain-specific motivation this multimedia effect was not evident for transfer. The effects of multimedia design were independent of motivation. Implications for future studies are discussed.

Understanding the effects of a teacher video on learning from a multimedia document: an eye-tracking study

The present study investigated the effects on students’ learning experience of adding a video of a teacher to an e-learning module. A total of 43 undergraduates were asked to learn the content of a pedagogical document either with or without a teacher video on the screen. Although video captures of teachers are increasingly being integrated into online courses, few studies have investigated their impact and the best way of optimizing them. According to the social-cue hypothesis, the presence of a teacher (face and gestures) positively influences learners’ motivation and engagement in their learning. By contrast, the interference hypothesis holds that the teacher’s presence can lead to poor performances, as it acts as a source of visual interference that diverts students’ attention away from the relevant information. By assessing subjective ratings and learning outcomes, the present study tended to support the social-cue hypothesis, as it showed that adding a teacher video on screen significantly improved students’ retention of the spoken explanations, without disturbing either their performances on diagram and transfer problems or the time needed to process the document. Eye-tracking data showed that students spent 25% of their time watching the teacher video. Adding this video had no significant observable effects on the subjective ratings (i.e., social presence, evaluation of the teacher’s motivational skills, situational interest, cognitive load). These results suggest that videos of teachers can be used to improve social cues in multimedia learning without creating interference effects.

Video-Based Analyses of Motivation and Interaction in Science Classrooms

An analytical framework for examining students’ motivation was developed and used for analyses of video excerpts from science classrooms. The framework was developed in an iterative process involving theories on motivation and video excerpts from a ‘motivational event’ where students worked in groups. Subsequently, the framework was used for an analysis of students’ motivation in the whole class situation. A cross-case analysis was carried out illustrating characteristics of students’ motivation dependent on the context. This research showed that students’ motivation to learn science is stimulated by a range of different factors, with autonomy, relatedness and belonging apparently being the main sources of motivation. The teacher’s combined use of questions, uptake and high level evaluation was very important for students’ learning processes and motivation, especially students’ self-efficacy. By coding and analysing video excerpts from science classrooms, we were able to demonstrate that the analytical framework helped us gain new insights into the effect of teachers’ communication and other elements on students’ motivation.

Getting real: the authenticity of remote labs and simulations for science learning

Teachers use remote labs and simulations to augment or even replace hands-on science learning. We compared undergraduate students’ experiences with a remote lab and a simulation to investigate beliefs about and learning from the interactions. Although learning occurred in both groups, students were more deeply engaged while performing the remote lab. Remote lab users felt and behaved as though they completed a real scientific experiment. We also examined whether realistic visualizations improved the psychological and learning experiences for each lab. Students who watched live video of the device collecting their data in the remote lab felt most engaged with the task, suggesting that it is the combination of the realistic lab and realistic video that was of the greatest benefit.     

Sensor-Augmented Virtual Labs: Using Physical Interactions with Science Simulations to Promote Understanding of Gas Behavior

Deep learning of science involves integration of existing knowledge and normative science concepts. Past research demonstrates that combining physical and virtual labs sequentially or side by side can take advantage of the unique affordances each provides for helping students learn science concepts. However, providing simultaneously connected physical and virtual experiences has the potential to promote connections among ideas. This paper explores the effect of augmenting a virtual lab with physical controls on high school chemistry students’ understanding of gas laws. We compared students using the augmented virtual lab to students using a similar sensor-based physical lab with teacher-led discussions. Results demonstrate that students in the augmented virtual lab condition made significant gains from pretest and posttest and outperformed traditional students on some but not all concepts. Results provide insight into incorporating mixed-reality technologies into authentic classroom settings.     

The effects of controversy,concurrence seeking,and individualistic learning on achievement and attitude change

The effects of cooperative-controversy, cooperative-concurrence seeking, and individualistic learning were compared on motivation, achievement, and attitudes toward the science subject being studied. Eighty-four fifth-grade students were assigned to conditions on a stratified random basis controlling for sex and reading ability. In all three conditions students studied whether wolves should or should not be a protected species. The results indicate that cooperative-controversy resulted in the highest achievement, greatest motivation to learn more about wolves, more positive attitudes toward the wolf, and more positive attitudes toward controversy.     

利用多媒体影/音录制提高大学英语口语教学

大学英语教学改革提倡充分利用现代信息技术,然而目前在口语教学中多媒体设备更多地被用作进行输入而非输出的工具。实际上,利用多媒体影/音录制功能能够增加口语输出、强化注意、提供学习动力与输出证据。在教学实践中,需要通过"布置口语任务——多媒体影/音录制——回放"三个步骤来实现利用多媒体影/音录制功能提高英语口语输出的教学模式。在影/音"录制——回放"两个关键环节上,学生不断地监控上一次录制下来的口语输出,通过对语音、语法形式、意义、语用、表达技巧等层面上逐步加强注意,从而达到提高英语口语能力的目标。     

Cell Phones Transform a Science Methods Course

Abstract

A science methods instructor intentionally encouraged cell phone use for class work to discover how cell phones can be used as research tools to enhance the content and engage the students. The anecdotal evidence suggested that students who used their smartphones as research tools experienced the science content and pedagogical information associated with the course in a more thoughtful and reflective way than their classmates, providing additional opportunities for metacognition.     

How an inquiry-based classroom lesson intervenes in science efficacy,career-orientation and self-determination

ABSTRACT

Three subscales of the ‘Science Motivation Questionnaire II’ (SMQII; motivational components: career motivation, self-efficacy and self-determination), with 4 items each, were applied to a sample of 209 secondary school students to monitor the impact of a 3-hour structured inquiry lesson. Four testing points (before, immediately after, 6 and 12 weeks after) were applied. The modified SMQII was factor-analyzed at each testing cycle and the structure confirmed. Only self-determination was shown to be influenced by an inquiry course, while self-efficacy and career motivation did not. Only self-efficacy and career motivation were intercorrelated and also correlated with science subject grades and subsequent achievement. Implications for using the modified SMQII subscales for research and teaching in secondary school are discussed.     

Learning to engage: how positive attitudes about the news,media literacy,and video production contribute to adolescent civic engagement

Many students enroll in video production courses in high school as part of a vocational, career, or technical program. While there has been an explosion of scholarly work in digital literacy in informal settings, less is known about how digital and media literacy competencies are developed through school-based video production courses. This study explores the relationship between civic engagement and the various multimedia instructional practices used in a high school video production course with a single-school convenience sample and an ethnically diverse population of students. Findings reveal that the best predictors of the intent to participate in civic engagement are having positive attitudes about news, current events, reporting, and journalism. Media literacy attitudes and a range of in-classroom learning experiences with video production are also associated with civic engagement.     

Mobile phones and/or smartphones and their apps for teaching English as a foreign language

Currently, there is an increasing trend in the shift from the use of traditional technologies such as a desktop computer towards the use of mobile technologies such as a mobile phone. Nearly all students nowadays own a mobile device and about half of them own more than one. Therefore, students are nowadays well equipped for mobile learning. The aim of this review is to explore the use of mobile phones and/or smartphones and their apps for teaching foreign languages, specifically English, and highlight their benefits and limitations for their use in the teaching of English as a foreign language. This was done by conducting a literature search in the databases Web of Science, Scopus, and ScienceDirect, and consequently, by evaluating the findings of the relevant studies. The findings indicate that the use of mobile phones and/or smartphones and their apps generate positive effects on learning English as a foreign language, especially in the development of learners’ vocabulary and their increased motivation to study. Nevertheless, more longitudinal randomized controlled studies are needed to confirm the efficacy of the use of mobile phone and smartphone apps on specific language skills and knowledge.
