For teachers to develop new beliefs regarding science teaching and learning, they must undergo a process similar to what they are trying to provide their students. Seventy-one Korean secondary school teachers including 20 earth science teachers have participated in such process. In the four-week long summer workshop hosted by University of Iowa, science teachers were exposed to several activities and lectures wherein they experienced student-centered lessons by playing the roles of both teachers and learners. This study examined the influence of such experience on the teachers’ beliefs about science teaching and learning. Changes in teachers’ beliefs were found in seven question items on the subjects of goals of science learning, the roles of science teachers and students, and classroom practices after workshop participation; it was found that teachers’ beliefs of science learning and teaching shifted from teacher-centered to student-centered. Although this shift does not denote a complete shift from one extreme to the other, it is meaningful to note that teachers’ beliefs after attending the workshop were interpreted to be either anti- or contrary to teacher-centered. One of the possible factors for making such positive changes may have been teamwork or the teachers’ cooperative learning experience.

The purpose of this study is to examine the change in the beliefs of regular classroom teachers after participating in a gifted education lectures and practicum as well as the effectiveness of the lectures and practicum. Each teacher was asked to complete a pre-/ a mid-/ and post-journal, detailing their expected characteristics and then describing what occurred and how their initial expectations were altered. The teachers mentioned high thinking skills, creativity, fast problem solving skills, and a lack of communication skills as intellectual characteristics of gifted students and high motivation and task commitment as social characteristics. They mentioned the characteristics in textbooks on pre- and mid-journals, but presented their observations in post-journals such as lack of communication skills, competitive spirit, and frustrations. The study found that teachers broadened their view of giftedness, recognized the need to adapt instructions for gifted students, realized the necessity of knowing the students to differentiate instruction patterns, and emphasized teaching-learning strategies for the gifted. These results contribute to the promise of having regular classroom teachers engage in a field experience with gifted students to supplement discussions about gifted education lectures.

The purpose of this study is to analyze gifted students' perception of the teaching activities at the gifted science high school (Busan Science Academy), in Busan, Korea, and to investigate the science experiment class practice. In this study, a questionnaire about the curriculum courses, teaching strategies, and evaluation method of the school was administered to 139 gifted students. The verbal interactions during the science experiment class were audio and videotaped, transcribed, and analyzed. The results of this study are as follows: First, according to the gifted students' perception, the credits of specialized courses and advanced elective courses need to be increased and the credits of general courses need to be reduced. Second, teachers at this school mainly use teaching strategies such as lecture, group activities, and discussion; on the other hand, the students prefer diverse teaching strategies such as discussion, lecture, experiment, inquiring activities, and problem solving. Third, students prefer a writing test assessment rather than a written report assessment or portfolio assessment. Fourth, the patterns of verbal interaction were different depending on the level of the teachers' questions and interactions between the students in the experiment class facilitated students' inquiry.

Two-dimensional shapes have a great influence on elementary school students' learning and are closely related to other content areas. Therefore, in this study, The Teaching and Learning Elements that should be taught in two-dimensional shapes were extracted from the literature. It also was analyzed that revised mathematics textbooks in the year 2015 were properly implemented with the teaching and learning elements. As a result of the analysis, in the case of Understanding The Concept, the activities in the textbooks are not able to recognize 2-D shapes which are focusing on shapes of the actual object. In the case of Classifying two-dimensional shapes according to the Criteria, the classification criteria were presented differently from what was learned in the previous course. In the aspect of Applying the Concept, the activities in order to Discuss two-dimensional shapes were not sufficient. Lastly, in view of the fact the 2015 revised curriculum is not considered with the relationship between two-dimensional shapes. For that reason, the following Knowing Relationships parts are insufficiently presented; Understanding the Relationship Between shapes through Definitions and Properties, Identifying the relationship between shapes throughout classification activities, and Discussing the relationship between shapes. Based on the analysis result of two-dimensional shapes, it is suggested that the finding of this research helps to enlarge the teaching methodology of triangles and provide educational perspectives for development in other shape areas.

The method of Lagrange multipliers, one of the most fundamental algorithms for solving equality constrained optimization problems, has been widely used in basic mathematics for artificial intelligence (AI), linear algebra, optimization theory, and control theory. This method is an important tool that connects calculus and linear algebra. It is actively used in artificial intelligence algorithms including principal component analysis (PCA). Therefore, it is desired that instructors motivate students who first encounter this method in college calculus. In this paper, we provide an integrated perspective for instructors to teach the method of Lagrange multipliers effectively. First, we provide visualization materials and Python-based code, helping to understand the principle of this method. Second, we give a full explanation on the relation between Lagrange multiplier and eigenvalues of a matrix. Third, we give the proof of the first-order optimality condition, which is a fundamental of the method of Lagrange multipliers, and briefly introduce the generalized version of it in optimization. Finally, we give an example of PCA analysis on a real data. These materials can be utilized in class for teaching of the method of Lagrange multipliers.

In a situation where the online learning is expanding due to COVID-19, the current maker education has limitations in applying it to classes. This study is to design the class of online maker education using artificial intelligence tools in elementary school. Also, it is to identify the responses to it and to confirm whether it helps improve the learner's computational thinking and creative problem solving ability. The class was designed by the literature review and redesign of the curriculum. Using interveiw, the responses of instructor and learners were identified. Pre- and post-test using corresponding sample t-test was conducted. As a result, the class consisted of ten steps including empathizing, defining making problems, identifying the characteristics of material and tool, designing algorithms and coding using remixes, etc. For computing thinking and creative problem solving ability, statistically significant difference was found. This study has the significance that practical maker activities using educational artificial intelligence tools in the context of elementary education can be practically applied even in the online environment.

The use of Unplugged Classes to easily teach the contents of Computer Science has recently become increasingly widespread. However, there has been a lack of research to discover which learner groups would benefit most from this method. Therefore, the intention of this research is to analyze learner's traits by examining score levels of post-class assessments made after Unplugged Classes. For this research, the learner's trait data has been divided into two groups: students' propensity towards computer comprehension and students' natural disposition. In addition to the verification of the relation between a learner's accomplishment level and the aforementioned data groups, meaningful applications of the data will also be recognized for practical use in elementary school classrooms. The results of this research will be valuable for elementary school teachers who utilize the Unplugged Class.
