Developing and integrating courseware for oral presentations into ESP learning contexts

This study reports on the development of ESP (English for Specific Purposes) multimedia courseware on oral presentations, and its integration into self-study learning and elective courses for students with different English proficiencies, as one solution to problems in ESP courses in Taiwan. The courseware design is based on Mayer’s multimedia learning cognitive theory, and the language learning focus draws on Chapelle’s suggested criteria for development of multimedia CALL. Evaluation of student performance with two different formats for courseware integration is based upon data from pre- and post-tests for preparing speech texts, and a questionnaire survey. The courseware provides authentic materials with a logical situational layout and a friendly interface design for learning ESP for oral presentations in international business and technical settings and offers rich and flexible learning activities with corresponding on-line self-evaluation so that students actively engage in cognitive processing. Students with different English proficiencies have different concerns about giving a presentation. Meanwhile, after students’ self-study for six weeks, regardless of level of proficiency, students’ learning effectiveness and satisfaction with the courseware integration were significantly improved, by qualitative and quantitative analysis. Such students’ improvement suggests success of the courseware design and learning effectiveness with its integration.     

An interactive whiteboard student survey: Development,validity and reliability

The interactive whiteboard (IWB) has become a popular technology for instructors over the last decade. Though research asserts that the IWBs facilitate learning in different ways, there is a lack of studies examining actual IWB use in classroom settings based on learners’ perspectives by means of valid instruments. The purpose of this study is to develop a valid and reliable interactive whiteboard student survey in order to evaluate the IWB use based on perceptions of students who have been taught with IWBs. In establishing the theoretical base of the survey, the Technology Acceptance Model (TAM) and constructivist learning theories were considered. In addition, with respect to IWB use in classrooms, a number of studies emanated from countries such as the UK, the USA, and Australia were examined, and similar research questionnaires and findings and also reflections of students about IWBs were utilized to create an item pool. A 39-item survey was conducted among middle school students (N = 263) from the city of Istanbul in Turkey. Collected data was exposed to exploratory factor analysis and resulted in a 26-item, three-factor survey, whose factors were named as the perceived efficiency of IWB, perceived learning contribution and motivation, and the perceived negative effects of IWB. The results of the analyses illustrated that this new IWB student scale, which explains 50% of the total variance with a good level of Cronbach’s Alpha coefficient (0.93) is a valid and reliable instrument designed specifically for measuring the use of IWBs in real classroom settings. Besides, theoretical foundations of interactive whiteboard use, the development process of the instrument, and results of validity and reliability analyses were discussed in detail.     

Using a voting system in conjunction with interactive whiteboard technology to enhance learning in the English language classroom

This study discusses the pedagogical potential of an interactive voting system used in conjunction with interactive whiteboard technology. The data discussed here are drawn from a qualitative study, carried out in the context of a British university pre-sessional programme in English for Academic Purposes and Study Skills for international students in the summers of 2003 and 2004. Research data were collected via a variety of ethnographic research instruments, namely classroom observations and feedback from critical colleagues, teacher’s field notes, video recording of classes, semi-structured interviews with students, and pre- and post-course student questionnaires. The findings indicate that the electronic voting system was seen to increase considerably the scope of interactivity during the lessons by helping students to enhance their development into active participants. However, the data have also indicated that the levels of interactivity in the approaches adopted in the context investigated could still be considered relatively “shallow”, and some suggestions have been provided to improve this aspect of technology use.     

A computer environment for beginners’ learning of sorting algorithms: Design and pilot evaluation

This paper presents the design, features and pilot evaluation study of a web-based environment -the SORTING environment- for the learning of sorting algorithms by secondary level education students. The design of this environment is based on modeling methodology, taking into account modern constructivist and social theories of learning while at the same time acknowledging the role of hands-on experience, the significance of students’ expressing their previous knowledge, the importance of interlinked multiple representation systems (MRS) and the role of constructive feedback on student learning. Although SORTING supports student learning of typical sorting algorithms such as Bubble-sort, Quick-sort and Selection-sort, it can also be adapted to integrate more sorting algorithms. The analysis of the data emerging from the pilot evaluation study of SORTING has shown that students used all the representation systems (RS) provided and found them attractive and easy to use. On the whole, student interactions within SORTING helped them to become aware of both the intuitive and the typical sorting procedures used, to conceptualize them, to overcome learning difficulties, to correct themselves and to make connections between different representations of the sorting algorithms used.     

Transition from traditional to ICT-enhanced learning environments in undergraduate chemistry courses

This paper describes a three-year study conducted among chemistry instructors (professors and teaching assistants) at a post-secondary institution. The goal was to explore the integration process of information and communication technologies (ICT) into traditional teaching. Four undergraduate chemistry courses incorporated a course website, an electronic forum, computerized visualizations, and Web-based projects, into their curriculum. The learning technologies were integrated to enhance inquiry-based learning, visualizations, and knowledge sharing. The current study investigated chemistry instructors’ perceptions toward ICT and their activities while practicing the newly introduced technologies. The findings showed that integrating new practices is a phase-dependent process that consists of promises as well as complexities. Four transition steps were found to characterize the integration of ICT-learning environments: non-active, support-dependant, partial-independant, and total-independant. Findings indicated that the transition from traditional to ICT-enhanced learning environments involves ambivalent feelings and dichotomy among instructors.     

Exploring the cognitive loads of high-school students as they learn concepts in web-based environments

This study measured high-school learners' cognitive load as they interacted with different web-based curriculum components, and examined the interactions between cognitive load and web-based concept learning. Participants in this study were 105 11th graders from an academic senior high school in Taiwan. An online, multimedia curriculum on the topic of global warming, which lasted for four weeks, provided the learning context. After students worked through the curriculum, their feelings about the degree of mental effort that it took to complete the learning tasks were measured by self-report on a 9-point Likert scale. An online test and the flow-map method were applied to assess participants' concept achievements. The results showed that curriculum components such as scientific articles, online notebooks, flash animations and the online test induced a relatively high cognitive load, and that a lower cognitive load resulted in better concept achievement. Also, students appeared to adopt different learning approaches that were corresponding to different levels of cognitive load.     

Who needs to do what where?: Using learning management systems on residential vs. commuter campuses

Learning Management Systems (LMS) are web-based systems allowing instructors and/or students to share materials and interact online. This study compared differences in LMS use between instructors and students at a large residential campus with students at a smaller commuter campus. Responses to an online survey about LMS activities and tools were categorized by three different interaction types: Learner–Instructor (LI), Learner–Content (LC), and Learner–Learner (LL). Aggregated log data was also analyzed to see if students’ use was consistent with their beliefs. Respondents from both campuses rate highly all activities and tools within the LMS. Findings suggest that residential students value activities and tools supporting LC interaction more than commuter students, while commuter students value activities and tools fostering LL interactions more than residential students. The aggregated log data was consistent with the survey data showing a higher level of activity in the most heavily used LC-oriented tools for the residential campus and higher activity in the LL-oriented tools for the commuter campus.     

Courseware development for semiconductor technology and its application into instruction

This study reports on the development of ESP (English for specific purposes) courseware for semiconductor technology and its integration as a “silent partner” into instruction. This kind of team-teaching could help overcome current problems encountered in developing ESP in Taiwan. The content of the material under discussion includes general knowledge about fundamental theories, process technologies and applications within the semiconductor industry. In the design of the whole courseware, five skills for learning English (listening, speaking, reading, writing, and translation) have been considered and a 3D multimedia technique has been used to promote learning interest, student engagement, and efficiency. The design of the courseware endeavors to mainly follow principles by [Mayer, R. E. (2001). Multimedia learning. New York: Cambridge University Press]. Students report they have benefited from the courseware implementation. Initial evaluations suggest that students are satisfied with practices for learning professional knowledge and English skills provided by the courseware. They report that the multimedia-assisted environment of the courseware promotes learning effectiveness. Students with higher achievement on the posttest showed better participation and motivation, made greater use of the multimedia and had a better understanding of the English content so that they are more competent to function in a professional and learner-centered ESP course using the courseware.     

Enhancing the recall of presented material

Many educators distribute either complete or incomplete handouts so students can follow along with their lectures. This research examines a teaching system that combines computer-generated graphics presentations and detailed outline handouts with blanks added. An experiment found that this system produced significantly higher short-term recall of a presentation when compared with note-taking on lined paper and with no note-taking. Visual design variables, specifically slide typefaces and type, were also manipulated to examine whether they had independent effects on short-term recall or influenced the benefits from note-taking. No significant main effects or interactions were found for the visual aid variables.     

How stress influences creativity in game-based situations: Analysis of stress hormones,negative emotions,and working memory

This study aims to integrate neuroscientific techniques into a behavioral experimental design to investigate how stress stimuli may influence stress hormones and negative emotions, subsequently affecting working memory (WM) and creativity in game-based situations. Ninety-six college students participated in this study, in which a game-based experiment lasting 90 min was employed. The main findings were that (1) the employed stress stimuli influence creativity during gaming through two routes: enhancing creativity through cortisol concentration and WM and decreasing creativity by provoking promotion-focused negative emotions (frustration and anger); and (2) the subjective negative emotions and objective cortisol responses do not consistently predict WM and creativity in game-based situations. Accordingly, appropriate challenges or stressors that help increase the cortisol concentration to an attentional level without provoking a strong sense of promotion-focused negative emotions should be considered when designing games aimed at teaching creativity.     

Effects of the application of graphing calculator on students’ probability achievement

A Graphing Calculator (GC) is one of the most portable and affordable technology in mathematics education. It quickens the mechanical procedure in solving mathematical problems and creates a highly interactive learning environment, which makes learning a seemingly difficult subject, easy. Since research on the use of GCs for the teaching and learning of probability in institutions of higher learning appears to be limited, a study was conducted to examine the effects of the use of GCs on students’ performance in probability. The study involved 65 pre-university students in a private institution of higher learning in Malaysia. Hypothesis testing showed that there is a significant difference in the mean score of the post achievement test between the experimental and control groups. Students in the experimental group displayed higher achievement than their peers in the control group in the Probability Achievement Test (PAT). Findings also showed that the use of GCs benefits students of all levels, that is, high, average and low mathematics achievers. Qualitative data provides a more lucid picture of how GCs aid in improving understanding and performance. Recommendations made will provide researchers, policy-makers and educators an alternative means of enhancing the quality of probability education.     

Effect of an interactive web-based instruction in the performance of undergraduate anatomy and physiology lab students

This study provides an understanding of how different interactive technology tools that are integrated into a Website can be used for teaching undergraduate human anatomy and physiology laboratory students. Technology tools refer to a Website that the authors created to teach the Cardiovascular System that includes dynamic tools such as the Pronunciation Corner and Spelling Bee, and an Interactive practice and test tool. The Cardiovascular System was chosen as the subject matter to modify based upon the results of a pilot study where students indicated difficulty in understanding this subject. In addition, a “Teacher Resources” tool on the Website allows any teacher to create their own Pronunciation Corner and Spelling Bee and use them for their classes. The statistical analyses showed that the experimental group students (who had access to the Website) took advantage of the technology tools provided and demonstrated significant improvement in their performance on the cardiovascular portion of the lab test.     

Lessons learned from the design of situated learning environments to support collaborative knowledge construction

The main characteristics of situated learning environments (SLEs) are: to provide authentic contexts, activities, expert performances and integrated assessment; to support multiple roles and perspectives, collaborative knowledge construction, coaching and scaffolding; and to promote reflection and articulation. However, current SLEs have two limitations: (1) not all of these characteristics are included, particularly lacking collaborative knowledge construction, in most cases; and (2) most SLEs are designed to support learning activities outdoors, but not indoors. This paper presents the implementation of an SLE that overcomes these two limitations. This SLE is based on bidirectional Quick Response (QR) codes, which are enhanced QR codes that not only provide information when scanned but also collect user-generated content. This “Bidirectional SLE” is evaluated in an experiment in which it is compared with an equivalent “Traditional SLE”, which is built upon traditional QR codes. The purpose of this comparison is to understand if using bidirectional QR codes as a mechanism to support collaborative knowledge construction in indoor settings has an impact on students' learning outcomes and on their impression of the learning experience. Two hundred fifty-three students participated in this experiment. Data collected from this experiment indicate that the students who worked in the Bidirectional SLE (1) received better scores, providing better and more complete answers, and (2) evaluated their learning experience better than their peers' who worked in the Traditional SLE. Finally, a cross-analysis of these results including teachers' opinions led to a set of lessons learned about the design of SLEs to support collaborative knowledge construction.     

A constructivist computational tool to assist in learning primary school mathematical equations

In constructivist principles, learning is a process in which individuals construct knowledge. Research in Mathematics Education looks for ways to make mathematics education less dry and more attractive. When solving polynomial equations of the first degree, it is very common for teachers to work with the mistaken idea of “changing the sign” when “moving” the member. To minimize this problem, a balance can be used to illustrate the idea of equilibrium and also properties of equality. The objectives of this study were (1) develop a computational tool to replace a conventional balance in practical mathematics exercises thereby solving two material challenges for Brazilian teachers: verifying the accuracy of balances and the lack of student physical and social activity through direct participation; (2) determine how substituting the conventional balance with a computational tool for the solution of first degree polynomial equations affected the aspects inherent in the learning process like motivation, cooperation, dialogue, discussion, reflection, reciprocity, negotiation and responsibility. The results indicate that the cognitive computational tool met the challenges of Brazilian teachers. First, because it lacks mechanisms that need to be verified for accuracy in order to demonstrate equilibrium. Second, because it allows the direct participation of students (physical experience) and the use of the tool in small groups (social experience). The hands on completion of the activity, realistic appearance, the interaction with the tool, visual feedback on the panel, and two students using the same tool awakened motivation, responsibility for completing the activity, dialogue, cooperation, discussion and reflection. Doing the experiment with others aroused concern about the learning of others and reciprocity of knowledge for the improvement of the procedure to be constructed for solving 1st degree equations.     

Applying a multimedia storytelling website in foreign language learning

Storytelling is a practical and powerful teaching tool, especially for language learning. Teachers in language classrooms, however, may hesitate to incorporate storytelling into language instruction because of an already overloaded curriculum. English foreign language (EFL) teachers in Taiwan report additional problems such as having little prior experience with integrating storytelling into language teaching, locating appropriate stories, and lacking the cultural and language abilities to handle storytelling in English. On the other hand, researchers have demonstrated successful usages of computer and network-assisted English learning. The researchers in this study have developed a multimedia Storytelling Website to study how web-based technology can assist overcoming the obstacles mentioned above. The website contains an accounts administration module, multimedia story composing module, and story re-playing module. In order to demonstrate the effectiveness of this Website in significantly facilitating teacher’s storytelling and children’s story recall processes in EFL classrooms, it was implemented in one elementary school to test its effectiveness in instruction and in resultant student learning. The results of the study support the significance and the education value of the multimedia Storytelling Website on EFL teaching and learning. If such a Website can be applied within elementary EFL classrooms, the quality of teaching and learning can be improved and students’ enjoyment and success in EFL learning may increase.     

Fostering positive attitude in probability learning using graphing calculator

Although a plethora of research evidence highlights positive and significant outcomes of the incorporation of the Graphing Calculator (GC) in mathematics education, its use in the teaching and learning process appears to be limited. The obvious need to revisit the teaching and learning of Probability has resulted in this study, i.e. to incorporate GC in the teaching and learning of Probability, specifically on the issue of attitudes towards learning probability. The objective is to examine the effectiveness of GC interactive learning, particularly on students’ attitudes towards Probability. A total of 65 foundation students participated in this study; 32 students in the experimental group and 33 in the control group. The teaching approaches varied between the groups. While the experimental group experienced the GC approach, the control group encountered the conventional teaching approach of chalk and talk. Students’ attitude towards learning probability was assessed using the Probability Attitude Inventory (PAI), was administered prior to and after the study. The results show significantly difference in the improved attitude towards Probability between the groups, particularly in terms of usefulness of Probability, interest in Probability and self-concept in Probability. This study provides evidence that learning Probability with GCs benefits students.     

The roles of embedded monitoring requests and questions in improving mental models of computer-based scientific text

Prior research has shown that people are likely to skim information presented digitally with the resultant deleterious effect on accurate mental models of the text. Teaching monitoring strategies and presenting text with adjunct questions are effective strategies for improving the mental models of readers of scientific text, but the two strategies have not been directly compared for studying text read from a computer screen. In the present study, participants were individually tested in two experiments in which they studied computer-based text on the heart and circulatory system while either reading the text with no interruption, answering adjunct inference questions, answering adjunct factual questions, or answering prompts for global or specific monitoring. Reading time was untimed but looking back was not available. Prompting for global monitoring was most effective for improvement of mental models as measured by scores in diagram drawing, concept map construction, factual memory, and generating inferences. Further, global monitoring did not require more time-on-task than the other methods.     

An attitude scale for smart board use in education: Validity and reliability studies

The main purpose of this study was to develop an instrument to measure the attitudes of elementary students towards smart board (SB) use in education. A sequential exploratory mixed method was used. So the study started with a qualitative approach to establish the content and face validity of the scale, followed by a quantitative approach to test the construct validity and reliability of the scale items. Ten students, one teacher trainer specialized in SB use, three teachers experienced in SB use, and a language expert participated in the qualitative part. Data from 203 elementary students from two local schools in Malatya, Turkey, were used to test the psychometric properties of ‘smart board attitude scale’ (SBAS). The exploratory factor analysis (FA) yielded a two-factor model with 10 items. The goodness of fit indices produced by confirmatory FA confirmed the fit of the model to the data. Reliability of SBAS was also proved through multi-analyses.
