The purpose of this study was to develop home economics(HE) teaching learning process plans by Gagne's instructional events using scaffolding of 'nutrition and meal of adolescents' unit according to the 2007 revised middle school HE curriculum. To achieve this purpose, the teaching learning process plans and worksheets using scaffolding according to Gagne's instructional event were developed for 5 periods, implemented to the 71 middle school students in Busan city, and evaluated by 21 home economics(HE) teachers and 71 middle school students. The content of the teaching learning process plans were composed of the subjects, 'impotance of nutrition and wellness', 'types of function of nutrients, 'Korean dietary reference intakes and characteristics of adolescent nutrition', 'nutrition problems, eating habits, and diet of adolescents', and 'future health and jobs'. HE teachers evaluated that the content of the teaching learning process plans were suitable to the middle school students, teacher's questions were accurate, and the teaching learning process plans were suitable, usable, and easy to implement in middle school HE class. The students who participated in the class were satisfied with the instruction by Gagne's events using scaffolding. They perceived that the contents and process of the instruction were understandable and interesting.

In the last 20 years, educators have made significant advances in their thinking about how students learn and what it is that teachers ought to teach. They attempted to teach thinking s kills and designed instructional programs to facilitate learning. The purpose of this study was to review metacognitive approaches in reading comprehension instruction, and to provide some practical implications to school teachers. First, this study reviewed the concept of metacognition. Metacognition can be divided by metacognitive knowledge and metacognitive experiences. Metacognitive knowledge consists of knowledge or beliefs about what factors interact to affect the outcome of cognitive enterprises. Metacognitive experiences are executive control of one's own cognitive process, which include planning, monitorning and evaluating. Second, this study attempted to investigate the processes of reading comprehension in the metacognitively based view. Third, this study reviewed three kinds of reading comprehension instruction. In the metacognitive approaches, instruction is viewed as constructive process in which teachers and students mediate and negotiate meaning from the instructional environment. In order to enhance reading comprehension, teachers should use examples, explicit instruction, modeling, and elaboration to provide sufficient scaffolding to students. The scaffolding gradually diminishes as students learn to use and apply the reading strategies on their own. Also, students should be encouraged to attribute successful reading to the use of appropriate strategies.

Robot programming allows students to plan an algorithm in order to solve a task, implement the algorithm, easily confirm the results of the implementation with a robot, and correct errors. Thus, robot programming is a problem solving process based on reflective thinking, and is closely related to students' metacognition. On this point, this research is conducted to develop a robot programming instructional model for tile enhancement of students' metacognition. The instructional processes of robot programming are divided into 5 stages (i.e., 'exploration of learning tasks', 'a teacher's modeling', 'preparation of a plan for task performance along with the visualization of the plan', 'task performance', and 'self-evaluation and self-reinforcement'), and core strategies of metacognition (i.e., planning, monitering, regulating, and evaluating) are suggested for students' activities in each stage. Also, in order to support students' programming activities and the use of metacognition, instructional strategies based on cognitive apprenticeship (i.e. modeling, coaching and scaffolding) are suggested in relation to the instructional model. In addition, in order to support students' metacognitive activities. the model is designed to use self-questioning, and questions that students can use at each stage of the model are presented.

The purpose of this study was to develop the problem solving instruction facilitating novice learner to represent the problem. For the purpose, we mainly focused on three aspects of problem solving. First, learner should represent the targeted problem and its solutions for problem solving. Second, from crucial notions of cognitive load theory, learner's mental load should be optimized for problem representation. Third, for optimizing students' mental load, experts may support making their thinking more visible and mapping from their intuition to expert practice. We drew the design principles as follows. First, since providing worked examples for the targeted problem has been considered to minimize analogical errors as well as reduce cognitive load in problem representation at line of problem solving and instructional research, it is needed to elaborate the way of designing. The worked example alternatively corresponds to expert schema that consists of domain knowledge as well as strategies for expert-like problem representation and solution. Thus, it may help learner to represent what the problem is and how to solve it in problem space. Second, principle can be that expert should scaffold learner's self-explanations. Because the students are unable to elicit the rationale from worked example, the expert's triggering scaffold may be critical in that process. The unexplained and incomplete parts of the example should be completed not by expert's scaffold but by themselves. Critical portion of the expert's scaffold is to explain about how to apply and represent the given problem, since students' initial representations may be reached at superficial or passive pattern of example elaboration. Finally, learner's mental model on the designated problem domain should be externalized or visualized for one's reflection as well as expert's scaffolding activities. The visualization helps learner to identify one's partial or incorrect model. The correct model of learner could be constructed by expert's help.

This research aims at suggesting a case of designing theme-based integrated learning for usage smart media. New approach and direction for developing a gaming instructional design was suggested which can encourage learners to participate in. Quest-based learning, the learning environment design where learners conduct various learner-centered activities, plays an important role of reinforcing the motivation, promoting experiential and cooperative learning based on social interaction. The design using QR codes has been proved to be able to offer the learner-centered learning environment which includes social interaction strategy required for learners expanding their cognitive structure, motivation enhancing strategy encouraging their consistent participation in learning, complex problematic situation and scaffolding strategy emphasized by constructivism. And it is expected to contribute to promoting the design of theme-based integrated learning which is being demanded in the educational environment recently by combining systematic design process and strategies.

Understanding of how teachers change instruction can help predict what kind of educational materials is supportive or appropriate. On the basis of this idea, we explored elementary teachers' PCK progression on specific topics of astronomy: planet size and distance in solar system. To identify the development of PCK over time, we utilized learning progression (LP) as a conceptual framework. The progression of teacher PCK can also be illustrated as the hypothetical pathway from novice to expert like LP. Eight 5th grade elementary teachers participated in this study. We observed participating teachers' astronomy classes with the same topic. In order to document topic-specific PCK of participating teachers, we developed an analytic protocol consisting of four categories: knowledge of curriculum, knowledge of teaching strategies, knowledge of assessment, and astronomical thinking practice. In addition, we monitored the changes in the four participating teachers' PCK for two years in order to validate the evidences of the PCK progression. Participating teachers in this study took some intervention by attending a four-week pre-meeting with the researchers to profile an adaptive instruction. Through this research, we profiled four and five different levels of PCK progressions in three knowledge components (curriculum, teaching strategies, student assessment) and one astronomical thinking practice (systems thinking), respectively. Participating teachers demonstrated various levels and pathways in each component of PCK. This study released the empirical evidences in fostering instructional scaffolding, which is appropriate to the level of PCK of science teachers on specific topic.
