It tends to be emphasized that mathematics is the important discipline to develop students' mathematical reasoning abilities such as deduction, induction, analogy, and visual reasoning. This study is aimed for investigating the present state about mathematical reasoning in secondary school. We survey teachers' opinions and analyze the results. The results are analyzed by frequency analysis including percentile, t-test, and MANOVA. Results are the following: 1. Teachers recognized mathematics as knowledge constructed by deduction, induction, analogy and visual reasoning, and evaluated their reasoning abilities high. 2. Teachers indicated the importances of reasoning in curriculum, the necessities and the representations, but there are significant difference in practices comparing to the former importances. 3. To evaluate mathematical reasoning, teachers stated that they needed items and rubric for assessment of reasoning. And at present, they are lacked. 4. The hindrances in teaching mathematical reasoning are the lack of method for appliance to mathematics instruction, the unpreparedness of proposals for evaluation method, and the lack of whole teachers' recognition for the importance of mathematical reasoning

Critical thinking ability based on a sound sense of logic is essential for analyzing a given engineering design problem and assessing it to arrive at the most plausible conclusion. Engineering design classes require students to organize their engineering design experiences through reports, and engineering design reports require detailed specifications of their tasks at each stage. Given the nature of these curriculums, design classes provide writing courses focusing on science and engineering within specialized fields, but there still lies many obstacles for communication education that embraces both general education and major subjects. This study proposes a specified step-by-step writing model for engineering design reports that encompasses critical thinking for the objective of systemizing design experiences from engineering design report writing. For the purpose of the study, the concepts and relationship between critical thinking and creative problem solving have been examined, followed by a proposal of application methods for critical thinking criteria and elements from a case example on engineering design. Furthermore, the study proposes a critical thinking-based assessment rubric for logical decision making at each stage of engineering design as well as a resulting model for engineering design report writing.

The purpose of this study was to analyze the ability to control variables and the ways by which variables are controlled. First, the assessment criteria for evaluating the students' ability to control variables were developed for 8th grade students. Second, the ways variables are controlled were classified from student activity reports. These students' answers were categorized into six types (type A~ type F). Type A is defined as the group that excelled in recognizing the importance of controlling variables, eliminating unnecessary variables and identifying manipulated, dependent and controlled variables. Third, the scores of ability to control variables (CV score) and the classroom test of scientific reasoning (Lawson SRT) scores were measured. The results indicated that the CV score was highly correlated with Lawson SRT scores (r=.67, p<.01). Therefore, the assessment criteria developed in this study was used to evaluate the ability to control variables (CV score) and to measure the students' scientific reasoning.

This study sought to explore the enhancement of the introduction of teaching and learning methods for Problem Based Learning (PBL) and the evaluation factors to evaluate them effectively through an understanding lecture in Cultural Content Planning. It was intended to incorporate a practical zero-volume education methodology of problem-oriented learning and sufficient leading learning to reflect storytelling in the entire process of completing a cultural content with culture, cultural content, and content planning. To this end, the role of teaching methods should be faithful to ensure that teamwork and cooperation can be done organically according to the educational field, practice and situation. Students who take classes were asked to meet demand, reflect it through surveys, apply real-world problems, and acquire the entire course. Learners had to cooperate with each other until planning cultural content and completing the results through classes, and they evaluated themselves and colleagues in teamwork until the last result was completed from creative ideas. The results were shared together and the students were able to investigate the necessary PBL evaluation factors for themselves, and the prior research and survey on the method of PBL evaluation was conducted to derive the factors of understanding of cultural content planning. The derived assessment elements were able to identify priorities between the assessment elements using basic statistics, word cloud analysis, and AHP analysis. The components of the assessment derived were communication skills, basic knowledge, reasoning process, expertise, and evaluation techniques. Through this article, I was able to lead the understanding of cultural content planning to problem-oriented learning classes and encourage students to be familiar and smooth.

This study aims to explore a learning progression for eight core concepts of middle school science using constructed response items in the national assessment of educational achievement (NAEA). For this purpose, a total of 7,390 responses of the 9th graders on 8 constructed response items in NAEA conducted in 2015 were inputted by computer and the inputted answers were analyzed and classified into different levels. After completing this process, five levels were set for each construct and a construct map was created according to the levels. In this study, the construct map was written in a progression-based rubric format, which was used as a criterion for leveling the answers of all students. In addition, the Rasch model was applied to measure the scores and achievements of the respondents by means of statistical analysis to correlate the scores of the students with the achievement levels of the constructs. Lastly, a preliminary learning progression was created by revising the construct map reflecting the results of Rasch model application. This study was meaningful in that it explored the possibility of developing the learning process by using constructed response items in NAEA. However, the preliminary learning progression developed in this study is still hypothetical and inferential because it is not longitudinally traced to individual students. Therefore, it is necessary to continually revise and supplement through iterative research process.

We developed $21^{st}$ century scientific literacy assessment instrument and applied it to explore the contents of seven Korean science textbooks. The $21^{st}$ century scientific literacy assessment instrument involved three dimensions (habits of mind, character and values, science as human endeavor). Each dimension consists of three sub-dimensions. Five science education experts assessed the content of textbook using criteria. We discussed issues in which the examiners responses did not match and reached an agreement on initial disagreement. As a result, we found that most Korean textbook contained contents on habits of mind, especially, communication, collaboration, and information management. We also found that most materials lacked information about character and values and science as human endeavor. Based on the result, we suggest that researchers and science educators need to consider all dimensions of the $21^{st}$ century scientific literacy when they develop curriculum and teaching materials. In addition, the rubric for $21^{st}$ century scientific literacy can be adopted as an assessment tool for examining curriculum, teaching materials.

This study was to analyze the characteristic of scientific argumentation in the classes for the gifted of elementary school. The participants of this study were 5 fifth graders and 9 sixth graders, 14 in total, from the basic unit schools for gifted students of J elementary school in Incheon city. And it constituted small scale groups made up of 2~3 students with similar or identical ability in scientific reasoning. It had set up hypothesis for each group before the experiment, and students had a group discussion as a whole after the experiment. Classes were conducted 4 times, all courses were recorded as a sound/video. The ability in scientific reasoning of the students was inspected, making use of SRT II by means of pre-survey, and their argumentation levels were analyzed, utilizing 'Rubric for scientific argumentation course assessment.' As a result, argumentations did not incurred in every class. Analysis in argumentations of the students resulted in low level argumentation. This means argumentation cannot incur based on that with the limit in understanding the principle of experiments over the threshold of textbook no matter that he is an gifted student or not. The student both in formal operational period and transition period (2B/3A), the ability of scientific thinking in upper level, was improved of his argumentative ability in an overall aspect. However, a student of concrete operational period, the ability of scientific thinking in lower level, had argumentation with still lower level even after the experiment at the moment of discussing with the students on the upper level of scientific thinking ability.

The purpose of this study is to develop an identification model for gifted students, based on class observations and nominations. The definition, issues and methods of identification were examined to achieve the research goal. Gifted identification model based on class observations and nominations consists of 4 steps: The first is the collection of multidimensional information on students, and the second is the evaluation of the students' portfolios with the rubric that has the criteria of rating scales on each information. At the third, students are observed in the class. Then the students are interviewed for the evaluation of their cognitive and non-cognitive characteristics. At the fourth, the identification committee makes a final decision for the selection of gifted students, after considering all the results from the steps. This model will be helpful to identify gifted students who are regarded to have potential abilities, especially economically disadvantaged students.

Computer and Information Literacy(CIL) is one of Key Competences in 21st century. Many countries, including Korea, have adopted related contents in their national curriculum for conducting software education. With this movement, many book-type instruction materials for software education have been developed in Korea. However, it is scarce to find researches that evaluate the instruction materials from the perspective of CIL. In this study, we selected 4 instruction materials which were distributed by government with 'SW centered society' web site as well as were developed to teach physical computing for elementary students. Also, we analyzed if they can foster students' CIL. First of all, the evaluation framework was developed based on 'The Manual for Authorized and Approved Textbook' and 'The 2018 ICILS(International Computer and Information Literacy Study) Assessment Framework'. Then, 12 school teachers who have professional insight of software education evaluated the 4 instruction materials with the framework. Averaging the score given by evaluators, we determined that which instruction materials were superior or not. Finally, we figured out the characteristics of superior and inferior instructional materials. Based on the results of this study, we suggested implications for developing instruction materials for physical computing education to build students' CIL.

The purpose of this study was to develop teaching-learning plans applying ARCS strategies for food safety education, focusing on units related to the 'food selection and safe cooking'. To achieve this purpose, this study was conducted in the following order of analysis, design, development, assessment I, revision I, assessment II, revision II, and completion. In the analysis stage, 2015 revised curriculum and middle school technology-home economics textbooks(12 kinds) contents of 'food selection and safe cooking' among content elements of core concept 'safety' were analyzed. In the design and development stages, teaching-learning plans, teaching-learning materials, and evaluation rubric for teaching-learning outcomes using the ARCS motivation strategy were developed. In the phases of assessment I and revision I, evaluation items were selected as open-ended questions about food safety education factors and ARCS strategies, and their validities were verified by four experts. The teaching-learning plans for nine lessons were revised based on the feedbacks such as evaluation plans considering the correspondence between instruction and evaluation, strategy to reinforce intrinsic motivation, correction of improper contents composition, and so on. In the phases of assessment II and revision II, the validity of the three items, including relevance of each teaching-learning to food safety education, suitability of learning goals, and appropriateness of motivation strategy, was verified by seven experts. The final teaching-learning plans for 10 lessons were developed by revising and supplementing the data by compiling opinions of the assessment II. It is expected that this study can contribute to food safety education for middle school students, and that teaching-learning plans which apply ARCS strategies for food safety education will be used as good references for school teachers and curriculum developers.
