The purpose of this paper was to develop evaluation procedures for blended instruction, focusing on the courses that are currently offered in the university. This study analyzed current evaluation procedures and instruments and suggested redesign the evaluation process for blended instruction. The evaluation procedures are designed based on the combination of objective-oriented and consumer-oriented evaluation approaches. It includes three stages: front-end (screening), formative evaluation, and summative evaluation. During the front-end evaluation stage, information regarding students' technology skills and attitudes towards online instruction and classroom instruction are suggested to collect and plan the instructional strategies accordingly. The formative evaluation is conducted during the semester to collect students' opinions about the course and instructors modify their instruction based on the evaluation results. At the end of semester, summative evaluation is to be conducted to collect the data to improve the course. Evaluation questions and components for each stage are developed to collect the data such as students' perceptions of the course, the usefulness of online instructional materials, the effectiveness of blended learning strategies, and students' satisfaction with the course.

As a preliminary approach to developing a bedside teaching program, this study analyzed the instructional models that have been suggested for bedside teaching. The objects of analysis were four models: the 'Cox model,' which is composed of an experience cycle and an explanation cycle; the 'best teaching practice model' by Janicik and Fletcher; the 'twelve tips to improve bedside teaching' by Ramani; and the SNNAPS model for outpatient education by Wolpaw, Wolpaw, and Papp. This study was conducted in three steps. First, we identified the major components of each model and analyzed their characteristics and limitations. Second, we compared each model in terms of four aspects: the learner, learning interaction, learning context, and organization management. Third, on the basis of prior analysis, the possibilities and potential problems of the models were explored. Based on this review of the existing instructional design models, we proposed an additional four key elements for designing a bedside teaching program: multi-layered learners, various learning environments and contexts, time management by using media, and self-directed design.

In this study, we investigated the characteristics of the pedagogical content knowledge (PCK) components and their integrations in the processes of developing performance assessment tasks of pre-service chemistry teachers who participated in the constructive performance assessment workshop. Eight pre-service teachers participated in this study. After three weeks of the constructivist performance assessment workshop, they developed their own performance assessment tasks. The think-aloud method was used to investigate their developing processes. Their activities were recorded and videotaped, and semi-structured interviews were also conducted. The analysis of the results revealed that the PCK component considered in the planning step showed similar frequencies for assessment, instructional strategies, students, and subject matter components. In the embodying step, assessment component was most frequent. In the discussion step, the frequencies for assessment, instructional strategies, and students components were similar. However, curriculum component and the subcomponent of science process skill were rarely used. The integrations among the PCK components were found to be centered on the instructional strategies component in the planning step and the students component in the embodying and discussion step. However, curriculum and subject matter components were rarely integrated with other PCK components. On the basis of the results, educational implications are discussed.

In this study, a part of high school science instructional materials is evaluated by Instructional Quality Profile(IQP) based on the Merrill's Component Display Theory(CDT). The CDT is based on the Gagne's assumption of different conditions of learning for different outcomes. The IQP enables the user to check both the consistency and adequacy of existing cognitive instruction. The IQP can be used to predict student performance, and also to design and develop new instructional materials. The instructional components are classified according to 5 task levels; An Use-Generalities on Newly Encountered Examples(UGeg), A Remember-Paraphrased-Generalities(RpG), A Remember-Verbatim-Generalities(RvG), A Remember-Paraphrased-Examples (Rpeg). A Remember-Verbatim-Examples (Rveg). The analyses are composed of 3 parts; Justifying the task level of objectives, Objective-test consistency, and Test-presentation consistency. The objectives, the presentations and the tests given in a teacher's guide and a textbook are analyzed. The results show that the task levels and the content levels of the objectives are not consistent with those of the tests. And the indices of the test-presentation consistency indicate the presentation problems of the instructional materials.

This study investigates the effect of instructional program using Nott & Wellington's" your nature of science profile" to facilitate the understanding about the nature of science for elementary preservice teachers. To do this. this study used posttest only control group design. The students in control group studied the topic by instructional program using textbook and reference book. Experimental group studied by instructional program: (1)evaluating personally one's understanding of the nature of science using Nott and Wellington's "your nature of science profile"; (2)studying the way of understanding the nature of science focusing five dimensions presented in it; (3)knowing other's understanding the nature of science; (4)discussing and evaluating reflectively the various aspect about it. Because the true understanding about the nature of science is not only to know about the method of science but also to know the target of science. We planned to evaluate the effect of instruction by such dichotomous way as evaluating simultaneously the understanding about the method of science and the target of science. Therefore the Questionnaire to evaluate the effect of instruction consisted two pairs of open-ended Questions: first pair is consisted of questions for the representation and judgement of scientific theory, second pair is consisted of questions for components and sources of scientific manipulation of the structure of science. The results of questionnaires by experimental group(n=75) and control group(n=77) are as follows: (1) Analysing responses about first pair of questions in dichotomous way, we identified four different patterns in students' understanding about scientific theory. And the instructional program using Nott & Wellington's "your nature of science profile" is not significantly effective in the distribution of patterns of understanding about scientific theory, but effective in driving out scientifically valid understanding, naturalistic realism, about scientific theory from the students having realistic aspect in representation of scientific theory; (2) Analysing responses about second pair of questions in dichotomous way, we identified five different patterns in students's understanding about structure of science. And the instructional program using Nott & Wellington's "your nature of science profile" is significantly effective in the distribution of patterns of understanding about structure of science, and effective in driving out scientifically valid understanding, dualistic-circular view or dualistic-circular view, about structure of science from the students having dualistic or dualistic aspect in components of structure of science.

Smart education is defined as creating new values through connecting educational elements based on smart devices and infrastructure. In the study, we propose a theoretical and procedural framework for developing smart learning activities, which is considered characteristic of smart education, as well as environments in smart schools of Sejong Special Autonomous city. In addition, we discuss an instructional model developed from the framework. A smart learning activity as a basic unit in instruction is represented as a block when design and instruction focuses on smart learning activities. The block consists of components from learning activities, motivation, information activities, and tools when a teacher has smart learning ideas. Based on the theoretical and procedural framework, the thought-sharing model (i.e., that learners share ideas and opinions with classmates, review classmates' work, and enhance their own work) is an instructional model that leads to smart education. We discuss considerations for developing instructional models using the framework.

This study investigated the interactions among the PCK components of pre-service secondary chemistry teachers considered in the processes of making written test items individually and in small groups. The processes of making written test items individually for 8 pre-service teachers was studied through the think-aloud method. The analysis of the results revealed that the 'assessment in science education' of the five PCK components was most frequently used in making test items. 'Curriculum for science education,' 'subject matter knowledge,' and 'students' were also frequently used although fewer than the previous component. However, 'instructional strategies and instruction for science education' was hardly used. The integrations between two or three components with various types were frequently found. However, integrations among four to five components were not found. The processes of making written test items in two small groups consisting of four pre-service teachers were observed. The analysis of the results revealed that the PCK components used in small groups were similar to those in the individual processes. However, 'curriculum for science education' was less frequently used, and the numbers of subcategories used at a relatively high frequency increased from other four components in small groups. In the aspects of integration, the proportion of the integrations between two components decreased and that for three components increased compared with those in the individual processes. The integrations among four or five components were also newly found. However, the integrations of 'curriculum for science education' with the other components were less frequently found. The integrations of 'instructional strategies and instruction for science education' with other components were still hardly found.

This study investigates the impact of Calculator-Based Ranger (CBR) activities in the performance of middle school students' graphing abilities of physical phenomena. Two issues about CBR activities on graphing abilities were addressed in this study; (1) the effect of CBR activities on graphing abilities, and (2) the influence of instructional styles on students' graphing abilities. Following the use of CBR activities, students' graphing abilities were significantly more developed in three components-interpreting, modeling, and transforming. Significant differences were found in students' achievement depending on instructional styles related to differentiation, which is closely connected to transforming distance-time graphs to velocity-time graphs. The findings of this study indicate that CBR activities may enhance students in constructing appropriate webs of related concepts and ability to qualitatively interpret graphs. Using collaborative CBR activities to introduce and explore graphing of physical phenomena is, therefore, recommended for inclusion in the secondary mathematics curriculum.
