Children’S Thinking

This paper reports sophistication levels in third grade children’s understanding of polygon concept and polygon classes. We consider how children endow mathematical meaning to parts of figures and reason to identify relationships between polygons. We describe four levels of sophistication in children’s thinking as they consider a figure as an example of a polygon class through spatial structuring (the mental operation of building an organization for a set of figures). These levels are: (i) partial structuring of polygon concept; (ii) global structuring of polygon concept; (iii) partial structuring of polygon classes; and (iv) global structuring of polygon classes. These levels detail how cognitive apprehensions, dimensional deconstruction, and the use of mathematical language intervene in the mental process of spatial structuring in the understanding of the classes of polygons.

We define spatial structuring as the mental operation of constructing an organization or form for an object or set of objects. It is an essential mental process underlying students' quantitative dealings with spatial situations. In this article, we examine in detail students' structuring and enumeration of 2-dimensional (2D) rectangular arrays of squares. Our research indicates that many students do not “see”the row-by-column structure we assume in such arrays. We describe the various levels of sophistication in students' structuring of these arrays and elaborate the nature of the mental process of structuring.

This research aims to acquaire the description of ability level elementary students third grade at district Ulaweng, regency of Bone. The population is the entire elementary students third grade at district Ulaweng, regency of Bone. Samples are drawn by random in every group supervision UPTD grade at district Ulaweng, regency of Bone.Since there are four group supervision, those four schools become samples in which elementary students third grade are the subject of research.Instrument of data collection uses test. Data of test result is then analysed by descriptive statistical technique in the form of distribution of frequency, aritmetic mean, standard deviation, and percentage.Based on analysis data, it is summarizedthat the levelofcalculatingabilityelementary students third grade at district Ulaweng, regency of Bone is considered low. It is then recommended to all stakeholders in academic field to make serious effort to enhance math learning process at elementary school.

The purpose of this study is to explore third grade elementary students’ Nature of Science (NOS) identities as a result of participating in a unit on electricity. The study took place in the context of a diverse third grade “at risk” (as identified by state regulations) classroom. Videotapes were made of all aspects of the electricity lessons, including pre-lesson class discussions, activities engaged in by students, and follow-up class discussions at the conclusion of each lesson. Findings revealed that third graders began to develop identities of persons who conceptualize NOS. Even though through one unit they did not address all aspects of NOS, they showed great development in their identities for young third grade students.

Everything that has been achieved by students after conducting learning activities is called learning outcomes. In learning science at the elementary school level,needed media to improve learning outcomes. One of the media that can be used is picture media which are considered easy to make and inexpensive. This study uses quantitative methods with quasi-experimental designs consisting of experimental and control groups. Based on the calculation of the t test of science learning outcomes of third grade students of state islamic elementary  between those who use and do not use picture media, the value of t-count is 14.527 and t-table is 2.05 at the significance level of 5%. From the two values it is known that t-count> t-table, then Ho is rejected or Ha is accepted, so there is a difference in the learning outcomes of third grade tate islamic elementary students between those who use and do not use picture media.

This research aimed to (1) analyze the use of ‘Hidden Object Media’ in teaching English for third-grade elementary students in SD Lab Undiksha Singaraja. The subject of this research was thirty seven of third grade students in SD Lab Undiksha Singaraja at even semester academic year 2016/2017. This research categorized as descriptive qualitative in the form of graphs and percentage. Some instruments were used to conduct this research. There was interview guide, observation sheet and questionnaire. There are four media that was trying out based on topic of animals and body parts. Each media consist of teacher’s guidelines, brief story, hidden object handout, and list of possible post activities. Based on the result of students’ interview and teacher’s questionnaire it was found that hidden object media were able to involve students in learning, able to motivate and help students learn new vocabularies. The percentage shows that more than 78% in every session students felt happy, more than 57% in every session students felt helpful and 100% students feel motivated and feel that the media were good for them to be used. Thus, this media was proper to use for teaching English for third grade students.
