The Relationship

<p>Jaring-jaring dapat membantu siswa membuat konsep hubungan antara objek dua dimensi dan tiga dimensi. Namun masih ada ketidakakuratan dalam menyusun jaring-jaring yang disebabkan oleh kemampuan spasial yang lemah. Tujuan dari penelitian ini adalah untuk menggambarkan kemampuan spasial siswa dalam membangun jaring-jaring kubus dan balok. Subjek penelitian adalah empat puluh siswa Sekolah Dasar kelas lima. Dari empat puluh siswa dipilih dua siswa untk diwawancara lebih mendalam terkait penyelesaian tugas jaring-jaring kubus dan balok. Hasil penelitian menunjukkan bahwa dalam menyelesaikan tugas penyusunan jaring-jaring kubus dan balok, subjek menunjukkan kelemahan dalam kemampuan orientasi spasial dan visualisasi spasial. Kelemahan pada orientasi spasial terlihat pada kemampuan subjek untuk melihat objek dari sudut pandang tertentu yaitu dalam mengenali dua jaring-jaring yang kongruen tetapi dianggap tidak kongruen. Sedangkan kelemahan visualisasi spasial nampak pada saat subjek yang tidak dapat membayangkan bahwa jaring-jaring dapat dilipat menjadi kubus dan balok.</p><p> </p><p>Nets can help students conceptualize the relationship between two-dimensional and three-dimensional objects. But there are still inaccuracies in composing the webs caused by weak spatial ability. The purpose of this study is to describe the spatial ability of students in constructing cube and beam webs. The research subjects were forty-fifth-grade elementary school students. Of the forty students, two students were chosen to be interviewed more deeply related to the completion of the task of the cube nets and the beam. The results showed that in completing the task of arranging cube and beam nets, the subject showed weaknesses in the ability of spatial orientation and spatial visualization. Weaknesses in spatial orientation are seen in the subject's ability to see objects from a certain point of view, namely in recognizing two nets that are congruent but considered incongruent while the weaknesses of spatial visualization are seen when subjects cannot imagine that the webs can be folded into cubes and blocks.</p>

This article describes the development and validation of a newly designed instrument for measuring the spatial ability of middle school students (11-13 years old). The design of the Spatial Reasoning Instrument (SRI) is based on three constructs (mental rotation, spatial orientation, and spatial visualization) and is aligned to the type of spatial maneuvers and task representations that middle-school students may encounter in mathematics and Science, Technology, Engineering and Mathematics (STEM)-related subjects. The instrument was administered to 430 students. Initially, a set of 15 items were devised for each of the three spatial constructs and the 45 items were eventually reduced to 30 items on the basis of factor analysis. The three underpinning factors accounted for 43% of variance. An internal reliability value of .845 was obtained. Subsequent Rasch analysis revealed appropriate item difficulty fit across each of the constructs. The three constructs of the SRI correlated significantly with existing well-established psychological instruments: for mental rotation (.71), spatial orientation (.41), and spatial visualization (.66). The psychometric characteristics of SRI substantiate the use of this measurement tool for research and pedagogical purposes.

The Relationship

Objectives: The aim of this study was to examine the relationship between the spatial abilities of medical school students and their learning in anatomy. Methods: The spatial abilities of the 120 students (74 females, 46 males) were examined using Mental Rotation Test (MRT). The relationship between the mental rotation scores and the mean scores of their practical and theoretical anatomy examinations was determined in terms of gender. Results: The study revealed that mental rotation skills of female participants were lower than males; however, there was no significant difference in their exam (theoretical and practical anatomy examinations) scores in terms of gender. The spatial ability of the students had a low level significant effect on their anatomy scores, regarding practical applications. Conclusion: The results of the study revealed a significant relationship between students’ spatial ability and their success in practical anatomy examinations. This suggests that improving spatial ability skills may have a significant contribution to practical anatomy learning and may be considered as a part of anatomy education.

AbstractFocusing on geometric morphometrics (GMM), we review methods for acquiring morphometric data from 3-D objects (including fossils), algorithms for producing shape variables and morphospaces, the mathematical properties of shape space, especially how they relate to morphogenetic and evolutionary factors, and issues posed by working with fossil objects. We use the Raupian shell-coiling equations to illustrate the complexity of the relationship between such factors and GMM morphospaces. The complexity of these issues re-emphasize what are arguably the two most important recommendations for GMM studies: 1) always use multivariate methods and all of the morphospace axes in an analysis; and 2) always anticipate the possibility that the factors of interest can have complex, nonlinear relationships with shape.

The Relationship

The paper reveals some aspects of the problem of forming a complex of qualities that characterize the phenomenon of creative leadership in school students. The interest in this problem is explained by the increased need of modern Russian society and its relevance in scientific psychological and pedagogical and socio-psychological problems. The prerequisite for the study was the contradiction between the urgent need for creative leaders in various spheres of production, management, in creative and spiritual life and the absence of a systematic purposeful state policy in this field. At the same time, it is stated that if in foreign science from the beginning of the 1960s, studies of the concept of creative leadership are carried out, but in Russian scientific thought, the concept of creative leadership is still poorly understood from the point of view of its formation. Several aspects of the problem of leadership are reviewed, such as the ability of a leader to lead other people to solve various problems, including creative ones; the concept of creativity is analyzed as the ability to think in an original, non-standard, creative way, to generate innovative cultural products. The phenomenon of creative leadership is considered by the authors, first of all, as a person’s expressed ability to lead a group of people to achieve various goals that are important for this group, to implement creative ideas and projects, while the directions, methods, means of their implementation are innovative. The paper presents the results of an experimental study conducted to determine the nature of the relationship between creative leadership and creative thinking. The novelty of the study is determined by the use of an original series of methods that allow for a comprehensive assessment of the formation of creative leadership in school students and the presence of a correlation between the indicators of the creative leadership methodology with various factors characterizing creative thinking.

Premarital Preparation

The high rate of divorce in young couples is motivated by psychological and spiritual unpreparedness. Premarital education is a resolution to minimize the divorce rate. This study aims to hack the knowledge and understanding of Muslim adolescents regarding marriage and marriage readiness from a psychology and Islamic law perspective. This type of research uses a descriptive quantitative data collection method using a survey in the form of a questionnaire. The research subjects were 820 adolescents aged 15-20 years who came from various levels of education, namely senior high school students (54.5%) and undergraduate students (45.5%). The results of this study indicate that there are several motivations for marriage for Muslim adolescents, namely (1) wanting to justify themselves by 49% (2) wanting to get attention and affection by 20.5%, (3) wanting to have children by 15.6%, (4) improve the economy by 10%, (5) follow parents wishes 4.9%. While the things that teenagers need to prepare for marriage are (1) Economy by 31.9%, (2) Studying Religion by 29.4%, (3) Education by 20.7%, and (4) Improving Character 18%. Adolescent understanding is still low on the purpose of marriage and the forms of marriage readiness. Indicated by the orientation and motivation of marriage is dominated by the fulfillment of biological and material needs. The implication of this research is to be able to provide a comprehensive view in terms of marriage readiness from the point of view of psychology and Islamic law as reference material for providing premarital preparation/premarital education to adolescents so that they can prepare for married life.
