Vector Approach

Many of high school students find difficulty in studying three dimensional geometry. They find difficulty in understanding three dimension objects such as cube, cuboid, pyramide, etc. Most students fail to make correct perception about the distance to calculate, when the problems are dealing with lines or planes. Only students with good spatial capability can solve such problems.  This research focused on making new approaching method to understand and then calculate the distance in a three dimensional objects. The approach is vector approach, including develop connection vectors, normal vector of a plane, and calculating distance from a point to certain line or plane using vector theorems. The Approach was tested by experimental study to a class of XII grade of high school students in SMAN 1 Parongpong, Indonesia,  consists of 30 students, and conducted in six meeting. A similar class treated with the conventional spatial approach as the control class. SPSS 20 was used to analyze the research data. Based on the research data analysis, the conclusion of the study was  that students treated with vector approach achieve higher performance improvement compare with the students treated with conventional approach. By using vector theorems to solve three dimensional problems, we turn the theory into action.   Keywords       :  Vector Approach, Three Dimensional, Distance, Line, Plane

This research aims to examine the construction of the discourse of religious and moral values within the official English textbook for Indonesian high school students and to expose the underlying ideology. The textbook analyzed is the official English textbook for junior high school grade VII, Bahasa Inggris: When English Rings the Bell. This study makes use of Fairclough’s three dimensional models, namely textual, processing, and socio-cultural analysis. In the level of textual analysis, the researcher addresses the issues of transitivity and modality. In the processing stage, the focus is on the issue of assumption. Meanwhile, the ideology investigation is done in the last level. The findings shows that the discourse of the religious and moral values are classified into four main categories: values toward one’s self (e.g being disicpline regarding the time), values toward others (e.g loving them and being attentive to their occupation and physical appearance), values toward animals (i.e. loving and being attentive to them), and values toward things around (i.e. being attentive to them). The Critical Discourse Analysis (CDA) investigation reveals that the discourse of religious and moral values within this book represents some dominating ideologies, such as the western-secular way of greeting people, the outschool activites of the mid-high social class, the rich’s-style house furniture, and the notion that beauty is identical with white skin and straight hair, the capitalism-driven economics system, as well as the idea of woman emancipation by the feminist movement.

Artikel ini bermaksud mengevaluasi validitas dan reliabilitas skala kematangan karir. Skala kematangan karir dirancang untuk mengumpulkan data penelitian tentang tingkat kematangan karir pada siswa SMA. Skala tersebut terdiri dari 12 item pernyataan yang disesuaikan dengan konstruk kematangan karir, yakni: kepercayaan diri dalam karir (KDK), ketidakpastian pilihan karir (KPK), dan pengetahuan terhadap karir (PTK). Hasil analisis faktor konfirmatori mengindikasikan tiga konstruk model cocok (<em>p-vales</em>= 0.50; RMSEA= 0.00; NFI= 0.99; CFI=1.00; GFI=0.99; AGFI=0.98). Selanjutnya, 7 dari 12 item pernyataan skala kematangan karir terbukti valid (<em>stadardized loading</em> berkisar antara 0.52 hingga 0.72; <em>t-values </em>berkisar antara 8.08 hingga 12.25) dan dua dari tiga konstruk skala kematangan karir reliabel (KPK=0.68; PTK=0.70). Hal tersebut menunjukan bahwa skala kematangan karir masih dapat digunakan sebagai instrumen pengumpul data dan alat asesmen.<br /><br /><em>The purpose of this article is to evaluate the validity and reliability of the career maturity scale. The career maturity scale is designed to collect research data on the level of career maturity in high school students. It is consists of 12 statement items tailored to the constructs of career maturity: career confidence, uncertainty of career choice, and career knowledge. The results of confirmatory factor analysis indicated that the three constructs of model was well fit (p-vales= 0.50; RMSEA= 0.00; NFI= 0.99; CFI=1.00; GFI=0.99; AGFI=0.98). Further, seven out of 12 statement items on career maturity scale proved valid (standardized loading ranged from 0.52 to 0.72; t-values ranged from 8.08 to 12.25) and two of the three constructs of career maturity scale are reliable (KPK=0.68; PTK=0.70). This shows that the scale of career maturity can still be used as an instrument for data collection and assessment tools.</em>

Self- knowledge and career knowledge of high school students are important aspects that need to be improved. This study aims to determine the significance of improvement in aspects of self-knowledge and career knowledge aspects of high school students through the classical service of career guidance using PowerPoint media based on object superiority effects, which was designed using the one-cycle classroom action research method in the students population of class XII of ITP high school at Surabaya city with a sample of 78 students taken by random class techniques. The research data was collected using the scale of students' self-knowledge and the scale of students' career knowledge. The research data were analyzed using parametric statistical t test techniques with the help of the SPSS for Windows version 23.0 program. The results of the data analysis of students’ self-knowledge obtained a value of t = -.399 at a significant level of .691 which means not significant, while the results of data analysis of students' career knowledge obtained a value of t = -1.758 at a significant level of .081, which also means insignificant. The results of this study indicate that the classic service actions of career guidance using PowerPoint media based on object superiority effects significantly cannot improve self-knowledge and career knowledge of high school students. Based on the results of this study, it is recommended that further research be conducted by using integrated guidance and counseling services in an effort to improve self- knowledge and career knowledge of high school students.

Penelitian ini bertujuan untuk mengidentifikasi apakah mahasiswa calon guru matematika mampu membangun situasi didaktis matematis pada siswa SMP dalam pembelajaran matematika berbasis ICT (Information and Communications Technology). Penelitian ini adalah penelitian deskriptif kualitatif. Subjek penelitian adalah mahasiswa calon guru yang telah praktik mengajar di sekolah. Subjek menggunakan aplikasi yang dibuat sendiri oleh subjek. Aplikasi yang dibuat berupa Augmented Reality (realitas bertumbuh), yaitu teknologi yang menggabungkan benda maya dua dimensi dan atau pun tiga dimensi ke dalam sebuah lingkungan nyata tiga dimensi lalu memproyeksikan benda-benda maya tersebut dalam waktu nyata. Hasil penelitian menunjukkan karakteristik situasi didaktis dalam pembelajaran matematika berbantuan ICT pada siswa SMP yang dibangun oleh mahasiswa calon guru adalah sebagai berikut: situasi didaktis matematis yang dibangun belum mengonstruksi pengetahuan siswa secara mandiri; situasi didaktis matematis yang dibangun cenderung berasal dari informasi yang disampaikan guru, bukan dari media ICT yang digunakan; dan ICT yang dilibatkan dalam pembelajaran belum mampu mengelaborasikan proses kognitif siswa dalam jejak pembelajarannya. Analysis of a didactic situation in ICT-assisted mathematics learning in junior high school studentsAbstractThis study aims to identify whether prospective mathematics teacher students are able to build mathematical didactic situations in junior high school students in ICT-based mathematics learning. This research is descriptive qualitative research. The research subjects were prospective teachers who had practiced teaching at school. The subjects used applications made by themselves. Those applications were in the form of augmented reality (reality grows), namely technology that combines two-dimensional and or three-dimensional virtual objects into a real three-dimensional environment and then projecting these virtual objects in real-time. The results showed the characteristics of didactic situations in ICT-assisted mathematics learning in junior high school students built by prospective teacher students were as follows: didactic mathematical situations that were built had not constructed students' knowledge independently; the built mathematical didactic situation tends to originate from the information conveyed by the teacher, not from the ICT media used; and ICT involved in learning has not been able to elaborate the cognitive processes of students in their learning footprint.

Cells are central to the study of biology, yet many learners have difficulties understanding the abstract yet fundamental foundation of life. Research suggests that students' conceptions of cells are reinforced by current biology learning materials, which represent cells as two dimensional, highly ordered, and mostly empty. These models also inaccurately represent the number, location, and size of organelles. We examine the effect of an inquiry-based three-dimensional virtual reality (VR) game on high school students' mental models of cells. Students reported that the game was more interactive and engaging than traditional ways of learning about cells and attributed an improved understanding of cells to their game experience. Students' post drawings of cells depicted more types of organelles, increased density of organelles, and additional complexity than their pretest drawings, indicating a movement towards more accurate mental models of cells. However, students' scores did not improve on their factual knowledge about cells between the pretest and the post-game biology assessments. We discuss the implications of incorporating game-based approaches and new technologies such as VR into biology education.
