In this paper, I propose a presentation examples of the development of teaching materials using Arduino. For this purpose, a six-step low-cost microcontroller teaching-learning development model was used, the steps being topic selection, exploration of implementation methods, experimentation, production of teaching and learning materials, implementing lesson plans, and improvement. After analyzing the composition of the source code and circuits introduced in the existing Arduino book, this content was reconstructed to fit the programming education context. A simple method of constructing a circuit using materials such as Arduino and a piezo buzzer is proposed to save time on circuit composition. Using this circuit, examples of use in teaching-learning activities for various programming content elements are presented. The core concept of this study is that it provides a direct experience of the content of C language programming exercises that can only be found on existing screens.

We studied spawning, hatching and larval growth of Amphiprion melanopus under laboratory conditions. Each time a fish spawned about 440 to 650 eggs. The eggs were hatched 9 days later. Nest colour of the eggs changed from clear yellow orange to greyish violet with processing of embryogenesis. With regard to spawning according to the substrates, the fish prefered red clay pot and ceramic pot to volcanic scoria and live rock. Hatching rate (%) of the eggs on the former substrates was significantly higher than that on the latter. The number of eggs varied with the food stuff supplied to the fish. The fish fed Tetra bits (commercial diet), meat of short necked clams and mussels, and astaxanthin showed significantly higher fecundity with 638 eggs than that fed only Tetra bits (477 eggs) or Tetra bits with meat of shellfish without astaxanthin ($549{\sim}553\;eggs$). Higher temperature ranging from 24 to $30^{\circ}C$ induced shorter incubation period and smaller total length, but higher hatching rate. The optimum salinity and L:D cycle with $60\;{\mu}mol$ photon $m^{-2}s^{-1}$ for hatching were 33 psu and 16:8, respectively. The newly hatched larvae about 4.6 mm in total length grew to 7.5 mm in one week, 18.8 mm in a month and 37.9 mm in 70 days after hatching.

This study aims to find out the effect of pre-service elementary teachers' experiences of inquiry performance in the life on their images about a scientist and science teaching anxiety. Thus, this study selected 162 college juniors who completed 'Science Teaching Material Research & Teaching Methods' for one semester at a university of education. Groups of 3 to 4 pre-service teachers were made to select one of the 10 experimental topics and inquired it for themselves, and make a presentation about the results before the other pre-service teachers. The results of this study can be summarized as below. Firstly, as a result of investigating pre-service elementary teachers' opinions about the characteristics of scientists, it was found that they thought of scientists prudent, intellectually superior, creative, and hard-working, but did not consider them artistic or religious, no matter if they had inquiry performance experiences. Especially, to such characteristics as intellectually-superior, creative, open-minded, outgoing and responsible, they showed more positive responses after inquiry performances. Besides, in scientists' activity types shown in pre-service elementary teachers' drawing pictures of a scientist, 'Experimental Activity' increased most after their inquiry performances, and in the place of activity, 'Laboratory' was most since it was related to activity types. Secondly, as a result of examining per-service elementary teachers' science teaching anxiety before and after inquiry performances, it was found that they showed statistically significant differences in all the domains, scientific knowledge, inquiry class preparation and inquiry class management. This finding could be interpreted as their inquiry experiences had positive effect on their having confidence in teaching science.

In school mathematics, the definition and concept of a differentiation has been dealt with as a formula. Because of this reason, the learners' fundamental knowledge of the concept is insufficient, and furthermore the learners are familiar with solving routine, typical problems than doing non-routine, unfamiliar problems. Preceding studies have been more focused on dealing with the issues of learner's fallacy, textbook construction, teaching methodology rather than conducting the more concrete and efficient research through experiment-based lessons. Considering that most studies have been conducted in such a way so far, this study was to create a lesson plan including teaching resources to guide the understanding of differential coefficients and derivatives. Particularly, on the basis of the theory of Historical Genetic Process Principle, this study was to accomplish the its goal while utilizing a technological device such as GeoGebra. The experiment-based lessons were done and analyzed with 68 first graders in S high school located in G city, using Posttest Only Control Group Design. The methods of the examination consisted of 'learning comprehension' and 'learning satisfaction' using 'SPSS 21.0 Ver' to analyze students' post examination. Ultimately, this study was to suggest teaching methods to increase the understanding of the definition of differentials.

The purpose of this study was to analyze research trends in clothing and textiles education focused on primary and secondary school education. Among the reviewed articles published between 1989 and 2008 in four journals including The Journal of Korean Home Economics Education, The Journal of Korean Association of Practical Arts Education, Journal of the Society of Clothing and Textiles, and Journal of the Korean Home Economics Association, 175 articles were related to clothing and textiles education. The most popular research field was teaching contents followed by teaching-learning method and teaching material, while clothing selection and self-expression, the general focus on home economics education and making clothing and household utensils were the popular research topics. In terms of research methods, about three quarters of articles used survey methods followed by experiment method and documentary studies. The rapid increase in research on clothing selection and self-expression and the decrease in articles on making clothing and household utensils seem to have had an influence on the government revision of The $7^{th}$ Curriculum.

The purpose of this study was to examine the effectiveness of utilizing a concept map as an instructional strategy to promote student achievement through semantical learning in elementary school on volcanoes. To analyze student achievement in understanding the concept of volcano, quantitative and qualitative analyses were performed through a written test for two different groups that were composed of 80 sixth-grade students: a control group that attended class using the conventional strategy and an experimental group that attended class using concept maps. The results of this study were as follows: First, the use of concept maps in class is effective in learning because of the higher understanding of the group that was using concept maps in the achievement assessment. Second, in their post-instructional understandings, no significant differences are shown between middle- and low-ranking students statistically, but a significant difference is shown between high- and low-ranking students or between high- and middle-ranking students. This indicates that the use of concepts maps in a class is more effective for the middle- and low-ranking students than for the high-ranking students. Third, in the repetitions of classes, the students learning with an aid of concept maps became accustomed to structuring the concepts of their learning subject in categories of relationships, hierarchies, cross-links, and examples easily.
