The constructive methods of teaching mathematics

The problem of teaching mathematics in Lithuanian schools envisaged in this article. The teachers often use the teaching methods of behaviourism. The widely used teachingmethods of constructivionism in the world are appearing in Lithuanian schools too. There is talked how mathematics teachers can easier start to use new progressivemethods by using IT in this article. There is reviewing how start to use constructive mathematics teaching methods by using Geometer’s Sketchpad in this article. There was appeared some problems for teachers by using Geometer’s Sketchpad in schools. So these problems help to find new step of investigating Geometer’s Sketchpad in teaching mathematics – to built the various sets of dynamic sketches for teaching and learning mathematics in basic schools. More than 800 dynamic sketches have been developed within 9th and 10th grades mathematics curriculum. Now is preparing set of sketches for 11th and 12th grades. Some constructive methods of teaching mathematic by using these sets of sketches are discussed in this article.The methods of comparative analyze and of synthesis of scientificworks are used in this article.

Justification on the Selection of Revised Edition of Bloom's Taxonomy in the Levels of Oral Questioning in the Process of Teaching Mathematic in Malaysia

This paper discusses a few taxonomies in education that are frequently used in various studies. Although there are other types of taxonomy that have been used by researchers in exploring the cognitive domain of the learning processes such as SOLO Taxonomy, Fink’s Taxonomy and Marzano Taxonomy, yet the use of the Revised Edition of Bloom's Taxonomy was considered as the most justified for the study on the cognitive levels of oral questioning used by teachers in the teaching of mathematics. This paper will highlight comparison between all of these taxonomies and further justify the researcher’s selection of the Revised Edition of Bloom's Taxonomy according to the suitability and needs of the study as well as the educational trends in Malaysia.

Abstrak: Sesuatu yang dibutuhkan dalam matematika untuk kesuksesan hidup menghendaki lingkungan pembelajaran yang mendukung dan mendorong kompetensi matematika baik secara teori maupun praktik. Dalam pendidikan, mengajar matematika harus dengan cara yang kreatif dan mampu menciptakan suasana lingkungan dimana siswa tertarik untuk belajar matematika. Penelitian ini bertujuan untuk meningkatkan hasil belajar matematika melalui implementasi pembelajaran kooperatif dengan model pembelajaran STAD. Metode yang digunakan adalah Penelitian Tindakan Kelas (PTK) dengan 2 siklus, setiap siklus terdiri atas 3 pertemuan. Hasil dari siklus 1 ditemukan bahwa 28 siswa (82.35%)mencapai batas ketuntasan (KKM) dengan rata-rata nilai 80. Pada siklus2, rata-rata nilai mencapai 87 dengan 34 siswa (100%) mencapai batas ketuntasan. Berdasarkan hasil analisis dan diskusi dalam peneilitian ini, dapat disimpulkan bahwa impelentasi pembelajaran kooperatif dengan model pembelajaran STAD dapat meningkatkan hasil belajar matematika.Abstract: The overwhelming need for mathematics comprehension for a successful life requires a learning environment that support and encourages both theoretical and practical math competency. In education, teaching mathematic should be creative and able to provide an environment where students are interested to learn mathematics.This study aimed to improve mathematic learning outcomes through the implementation of cooperative learning type STAD learning model. The method used in this research was a Classroom Action Research by conducting three meeting for each in two cycles. The result of the study in first cycle was found that 28 students (82.35%) meet the school competency with average grade 80. In the second cycle, the average of learning achievement reached 87 with 34 students (100%) meet the school competency. Based on the analysis and discussion of the research, it is concluded that the implementation of cooperative learning type STAD learning model can improve mathematic learning outcomes.

PEMBELAJARAN MATEMATIKA DENGAN OPERATOR DASAR UNTUK ANAK SEKOLAH DASAR BERBASIS MOBILE

The concept of teaching mathematic is most important for educators by understanding and application of mathematics content that cater to students, especially primary school students. extending the interesting material, as well as providing assistance to the student to take assessment can assist in attraction, concentration and success in understanding mathematics. It is always related because not all students in a class is able to understand the material quickly, then the required factors that have an interest for children. The interesting will become the factors that support students in learning, if these factors can also be conceptualized as children's activities are carried out every day, it means that if the school use the curriculum, and the home environment playground are always supervised by the parent. so the Interesting in mathematics lessons can be realized also in the integration of emerging technologies, especially mobile phones. The majority the students today have the tool, it will be more efficient to develope of mathematical material is also contained in the mobile. The development can be implemented in mathematic education game. Games designed by researcher wishes to develop mobile based learning materials, especially in mathematic. the Experiments have performed in the implementation of mathematic games with basic operators to produce the final value of the overall respondents who rate amounted to 84.4%. it means that the level of engagement users, especially students very well in playing to respond the educational game designed.

The effect of sequence in the acquisition of three set relations; an experiment with preschoolers

By its very nature, mathematics content has an inherent logical tructure. An instructional analysis of a mathematics concept or principle would consist of a list of prerequisite mathematical learnings deemed necessary for the logical development of the given concept. Inherent in the analysis would be hierarchal relationships between and among various prcrequisite learnings based on the structure of the discipline. Hence it is generally agreed that when teaching mathematic one should follow the structure of the content in determining instructional sequence.
