 Linking The Effectiveness of Streaming Video with Web Based Text in Online Course: Comparative Study on Three Types of Online Instruction for Korean College Students
 
 

JeongChul HEO(Korean Educational Development Institute)

This study is to identify whether three types of online instruction (text-based, video-based, and video-based instruction without text) and age category have a different influence on students’ comprehension and motivation. Online students were randomly assigned to one of six groups, and they attended two-week online lectures via Course Management System. The comprehension test and the short form of IMMS were implemented when 114 participants accomplished two-week online lectures. The results revealed that using instructional video in online instruction is more effective instructional medium than text only in order to promote learner’s motivation. Besides, older adults aged 41-60 are significantly different from younger adults (21-40 years old) in terms of students’ comprehension. Furthermore, three types of online instructions are likely to be influenced by age category.

Lessons Learned from Conducting Design-Based Research Studies
 
 

Ji-Yeon LEE(Inha University)

Design-Based Research (DBR) focuses on developing key principles of interventions to advance both theory and practicalities of dissemination (Brown, 1992), yet its methodological details have not been quite established. Thus, the purpose of this paper is to address the pragmatics of DBR by sharing the researcher’s reflections on conducting a longitudinal DBR project for five years. In an attempt to advance college teaching practices as well as theories related to student plagiarism, the project focused on refining “humble” theories on how and why college students engage in plagiarism to design classroom interventions for promoting academic integrity. Similar to the Integrative Learning Design (ILD) framework proposed by Bannan-Ritland (2003), but conducted in a much simpler and less formal format, this study followed DBR cycles from initial conceptualization to design and enact instructional interventions in authentic contexts while collecting both quantitative and qualitative data from each phase. Finally, the paper addresses some challenges encountered throughout the DBR project as well as the lessons learned from this experience. Like many previous DBR studies whose practical relevance is limited to local context, the findings from this study may not be easily generalized for other contexts.

Vibration Tactile Foreign Language Learning: The Possibility of Embodied Instructional Media
 
 

Yoon Cheol JEONG(Chungnam National University)

On the basis of two premises and embodied cognition theory, the vibration tactile learning is proposed as an effective method for foreign language learning. The premises are: the real nature of language is sound and the source of sound is vibration. According to embodied cognition theory, cognition is inherently connected to bodily sensation rather than metaphysical and independent. As a result, the vibration tactile learning is: people are able to learn foreign language better by listening to sound and experiencing its vibration through touch rather than solely listening to sound. The effectiveness of vibration tactile learning is tested with two instructional media theories: media comparison and media attribute. For the comparison, an experiment is conducted with control and experimental groups. The attributes of vibration tactile media are investigated in points of relationships with the learning process. The experiment results indicate a small effect on the increased mean score. Three kinds of relationships are found between the media attribute and learning process: enforced stimulus, facilitated pronunciation, and assimilation of resonance to sound patterns through touch. Finally, this paper proposes a new theoretical development for instructional media research: an embodied cognition based media research and development.

Design Implications for Teachers’ Tools in Differentiated Instruction through Case Studies
 
 

Hyunjin CHA (KERIS)

The diversity of students is getting increased in the contemporary classroom. To deal with the diversity, differentiated instruction (DI) should be considered as a way of providing alternative approaches to content, process and product according to the students’ readiness, interest, and learning needs. Teachers have problems and difficulties in supporting different student’s needs. In fact, teachers need proven tools including framework, guidelines or computing systems to help to practice DI in real context. According to the activity theory, tools influence on how people act and think and even their social practice, playing a crucial role in mediating the activities with people. In DI practice, there are also some studies about physical and abstract tools, but they have been not widely utilized by teachers in real schools. It means that more innovative tool to promote DI might be required. Therefore, to design a better tool to mediate the DI activities with teacher, case studies were conducted. In order to elicit the design implications, two physical and two abstract tools for DI practice were analyzed as case studies. Through the analysis of the case studies, eight design implications better to facilitate DI practice were suggested. This study has implications in suggesting design guidelines for teachers’ tools to facilitate their DI practice by analyzing case studies in DI practices for an innovative tool in the educational practice.

The Effectiveness of Cognitive Scaffolding in an Elementary Mathematics Digital Textbook
 
 

Jeong-Im CHOI (Kwandong University)

The purpose of this study is to find a way to improve digital textbooks for self-regulated learning by applying cognitive scaffolding designs to an elementary math digital textbook and examining the effectiveness of the system. Hence this study was conducted in two steps. First, a framework for scaffolding design was devised by examining the problems and difficulties students encounter when using a mathematics digital textbook. Second, after the digital textbook was revised by applying the scaffolding design frameworks, the effectiveness of the scaffolding framework was examined by comparing students’ achievement levels in an experimental group and that of students in a control group. Seventy fifth-graders participated in this study. Students were divided into two groups: an experimental group and a control group. The students in the experimental group studied with the revised version of the digital textbook and the students in the control group studied with the original version of the digital textbook. The students received a pretest before the experiment. After the experiment, they took an achievement test and completed a usability questionnaire. The data were analyzed by ANCOVA with the SPSS Windows version. The results revealed that the students who used the revised program (to which design strategies for scaffolding were applied) showed higher levels of achievement than those who used the original version. In addition, students in the experimental group generally showed higher scores on the usability survey, which consisted of four sub-categories such as ‘effectiveness’, ‘efficiency’, ‘satisfaction’, and ‘learnability’. There was a statistically significant effect on ‘efficiency’. These results implied that scaffolding strategies were effective for mathematics learning through the use of an elementary digital textbook.

We conducted an empirical study with 8 middle school students in Korea to investigate the usability and usefulness of our self-designed Digital Textbook. The Stimulated Recall (SR) Method using Morae software was utilized to analyze the learners’ task behaviors and mental operations while using the Digital Textbook to learn English. Collected qualitative data indicated several problems in terms of the usability and usefulness of the Digital Textbook. The findings are summarized and some implications are discussed for further revision of the Digital Textbook and validation of the SR method as a usability-usefulness test tool.
