This study aims to analyze the teaching and learning methods realities and needs in the subjects 'The basis of the Invention Patent'. To this end, research and analysis of the subjects 'The basis of the Invention Patent' the teacher and take advantage of their current teaching and learning methods, 'The basis of the Invention Patent' subject teachers to recognize the most desirable teaching and learning methods, subjects 'The basis of the Invention Patent' of teaching and learning and the operating requirements of the difficult matters. Survey of 48 schools across the country in high school teachers to teach the subjects 'The basis of the Invention Patent' was conducted, the results of this study are as follows. First, a high percentage of theoretical learning activities, teaching methods, such as 'lectures' and take advantage of the higher percentage. Module was to conduct classes such as 'project', 'lab experiments', 'discussion', 'investigation' by taking advantage of the high proportion of practice learning activities. Second, Higher requirements for the experience and practice of student-centered 'lab experiments', 'project', 'Case Studies', 'field trips' and theory-driven rather than 'lectures'. Third, 'The basis of the Invention Patent' subjects 'Teaching and learning important when operating requirements for the degree' as a whole was highly recognized. in particular, operating requirements for teaching and learning in accordance with the former college of education of education than non-group differences were higher overall response. Fourth, 'The basis of the Invention Patent' subjects 'Teaching and learning difficult when operating your degree' as a whole was highly recognized. In particular, was recognized by difficult questions, such as lack of preparation classes due to excessive work, educational facilities and equipment shortage, lack of prior knowledge about the subject, individual differences of the students considering the difficulties, student's

In this study, a teaching units for teaching and learning of secondary preservice teachers' mathematising is designed, focusing on reinvention of Bretschneider's formula. preservice teachers can obtain the following through this teaching units. First, preservice teachers can experience mathematising which invent a noumenon which organize a phenomenon, They can make an experience to invent Bretscheider's formula as if they invent mathematics really. Second, preservice teachers can understand one of the mechanisms of mathematics knowledge invention. As they reinvent Brahmagupta's formula and Bretschneider's formula, they understand a mechanism that new knowledge is invented Iron already known knowledge by analogy. Third, preservice teachers can understand connection between school mathematics and academic mathematics. They can understand how the school mathematics can connect academic mathematics, through the relation between the school mathematics like formulas for calculating areas of rectangle, square, rhombus, parallelogram, trapezoid and Heron's formula, and academic mathematics like Brahmagupta's formula and Bretschneider's formula.

We confront incessant choices in life. A person or a group stands at a crossroad continuously and make decisions under limited conditions in each time in order to achieve a goal. These series of processions are referred to as decision making and dominates our actions. Based on this view, the decision making is crucial and it secures its own position in school education as well as in real life. The purpose of this study is to develop decision making skills instructional model that can be applied to improve decision making skills in technological subjects. The components of decision making skills in technological education was problem recognition, problem identification, alternative production, alternative assessment, optimum selection, optimum evaluate. An instructional models for improvement of decision making skills in technology education and examination was designed according to the components of decision making skills in technological education. Depending on the components of decision making skills developed a teaching material to experience each step. And in the teaching material was to verify the improved decision-making skill. Accordingly, a decision making instruction model in technology is expected to contribute to enhance students' decision making skills.

Education, Science and Technology Department in January 2012, announced the advancement of mathematics education scheme. Select a textbook of storytelling method in policy by this, it is easy to understand the math, and that you can learn happily, was fabricated and spread. In this study, we selected three of the textbook that describes the set to its characteristics the application of storytelling in a textbook of mathematics 13 different middle school that will be used from March 2013. And of research that the textbook is to analyze the reflected reality of storytelling that is part of the advancement scheme of mathematics education content and direction and basic curriculum of current. View by presenting instead I is an object of the present invention. Six components of storytelling in the teaching and learning context that is proposed in the Park's study (2012) are used to analyze. Those are 'Persona', 'empathy', 'analogy', 'aesthetic experience ', 'plot' and 'time'. The data were analyzed storytelling was used to introduce the nature and mathematical concepts in math textbook based on these elements 6. That is looking at the ratio of the presence or absence of reflecting elements of storytelling on teaching and learning context that the data storytelling meets much the elements of storytelling to investigate the characteristics of each textbook. It is expected to provide the information and resources needed to develop methods and materials that can be studied to be interested in conjunction with real life mathematics as a result of this study.
