  • 본 논문에서는 초등학생 학습자의 기초 알고리즘 개념 습득을 위한 Think-aloud 기법 적용 프로그램을 제안한다. 이 프로그램은 추상적인 대상에 대한 논리적 사고가 어려운 초등 학습자들에게 알고리즘 개념 및 표현 방법을 구체적으로 가르칠 수 있는 기법인 Think-aloud 기법을 활용한다. 연구는 ADDIE 모형에 따라 이루어졌으며, 개발된 프로그램의 내용으로는 교육과정의 성취기준에서 다루고 있는 세 가지 구조(순차, 반복, 선택)를 약간의 변형을 거쳐 다루었다. 또한 종합 연습을 통해 다양한 교과와 실제 생활이 알고리즘과 관련지을 수 있음을 알게 하였다. 후속 연구로는 개발된 프로그램의 검증 및 수정과 실제 현장에의 적용, 프로그램에 대한 전체적 평가 및 최종 수정이 이루어질 것이다.

  • In this paper, we propose a think-aloud program for acquiring abstraction concept. Think-aloud is a technique, which is good for teaching higher-order thinking skills to learner. We intend to propose a program for teaching abstraction concept to learners directly, as software education is being reinforced in the current education policy. For the study, we develop a program depending on ADDIE model. According to these steps, we analyzed related works such as computational thinking, think-aloud technique, and direct instructional model. After that, we split and structuralized the learning tasks for achieving a goal. And then, we constructed steps for the instruction and detailed contents of the program. We did a survey for verification to nine experts and we corrected the program according to it.

  • This study aimed to improve our understanding of users' cognitive processes based on think aloud protocols generated during the retrieval process of an online database. It analyzed think aloud protocols generated by participants while performing pre-defined tasks using an online database. The protocols were encoded using the open coding method. As the results, four broad categories including retrieval, system format, system functionality, and information were drawn, and 21 detailed categories were generated. Based on the results, suggestions for the design of online databases were provided.

  • The purpose of this study was to analyze task commitment types of science learning in high school students' biology classification. Thirty students were selected as the representatives of five task commitment types according to task commitment type inventory scores. They participated in think-aloud biology classification task. To analyze the procedural characteristics of task commitment, a coding scheme and think-aloud task were developed. Characteristics of respective task commitment types were identified from the result of the think-aloud protocol coding analysis. They are TGC(task goal commitment) type, LGC(low goal commitment) type, CC(conditional commitment) type, SC(suspended commitment) type, and DC(delayed commitment) type. Findings gained from this study are expected to serve as the foundation of task commitment enhancement strategies and as the information on the characteristics of each task commitment type. Also, future studies are required to investigate the commitment-related properties not only in biology classification but also in other science learning situations.

  • This study investigated students' verbal behaviors in paired think-aloud problem solving. High school students in chemistry classes were asked to use 4 stage problem-solving strategy through paired think-aloud problem solving, and their small-group behaviors were audio/video taped. Verbal behaviors of the solvers and listeners were classified into 8 categories. Solvers frequently exhibited the behaviors of 'require agreement', 'provide', and 'modify', and listeners frequently exhibited the behaviors of 'agree', 'ask', and 'point out'. With behaviors exhibited frequently, the verbal interaction between solvers and listeners were also investigated. In studying partial correlation between verbal behaviors and the improvement of problem-solving ability, listener's 'agree' and 'point out', and solver's 'modify' were positively related with listener's improvement. However, there was negative correlation between listener's 'point out' and solver's improvement. In a perception questionnaire, many students were found to perceive that the paired think-aloud problem solving helped them to be aware of the problem-solving processes. However, some listeners also perceived that it was difficult to know solver's problem-solving processes.

  • The purpose of this research is to propose a novel social LMS developed for group collaborative learning with a think-aloud tool integrated for sharing cognitive processes in order to improve group collaborative learning performance. In this developmental research, the system was designed with three critical elements: the think-aloud element supports learners through shared cognition, the social network element improves the quality of collaborative learning by forming a structured social environment, and the learning management element provides a understructure for collaborative learning for student groups. Moreover, the three critical elements were combined in an educational context and applied in three directions.

  • The purpose of this study is to provide a cost effective usability test model for business web site development. In this study, we present a usability test model that combines Concurrent Think Aloud, performance measurement, coaching method, and remote test method. Testing target was the consortium website of electronic information joint licensing. Test participants were actual users selected by their task roles and proficiency in different levels. We improved the system by reflecting the results of user test analysis and re-tested usability test again. The result showed that usability of all participants was improved in the aspect of the time required and the complexity of mouse trajectory. It is expected that the usability test model presented in this study can be used to cost-effectively evaluate and analyze business web sites. We suggest that research various usability test model considering the characteristics of websites.

  • In this study, the effects of grouping by extraversion and introversion in paired think-aloud problem solving using a four-stage problem-solving strategy emphasizing planning and checking stages were investigated. Prior to the instructions, the students' extraversion/introversion in three high school classes (N=87) were examined, and those classes were randomly assigned to the homogeneous, the heterogeneous, and the control groups. The test scores of the two treatment groups were significantly higher than those of the control group in the problem-solving ability. However, there were no significant differences in learning difficulty and self-efficacy. Although there were no significant differences between the scores of two treatment groups in the subcategories of the perception of treatment, the test scores of extroverts were significantly higher than those of introverts in the perception of performing listener's role, the preference to problem solving strategy, and the preference to paired think-aloud problem solving.

  • Purpose: The aim of this study was to identify thinking strategies in the complicated decision-making process based on real patient-based data of triage nurses in the emergency department (ED). Methods: This study used the 'think aloud' method to collect data from 8 triage nurses from one general hospital ED in South Korea. The data were analyzed with protocol analysis using thinking strategies. Results: The triage process was divided into three stages. The first stage consisted of 8 thinking strategies, including searching for information. They used intuition based on directly observed concepts for identifying a crisis. The second stage consisted of 17 thinking strategies related to the decision-making process. They assessed patients and generated a hypothesis to try to understand their health problems through analytic thinking. The third stage consisted of 10 thinking strategies, including qualifying. They considered the situation of the ED and properly triaged the patients. During the triage process, they frequently used judging the value and searching for information on 17 thinking strategies. Conclusions: Triage nurses demonstrated various connected thinking strategies for each stage. Based on our results, further studies should be done to develop a triage education program.

  • In this study, in order to explore the contextual elements of book use that were overlooked in the existing book recommender system research, for 15 avid readers with various book search backgrounds, the contents generated in 6 book search situations were collected through the think-aloud protocol. By using content analysis from the collected book use contents, not only the internal and external appeal factors affecting book use, based on the 'appeal factor', the theoretical concept of the readers' advisory service, but also information sources and search methods regarding book use were identified and categorized. The results of this study can be used to extract and reflect meaningful attribute data in the future book recommender system design process.
