Permasalahan Pembelajaran Matematika Sekolah Dan Alternatif Pemecahannya, Hasratuddin Hasratuddin

PYTHAGORAS : Jurnal Matematika dan Pendidikan Matematika

Matematika adalah ilmu deduktif yang mengacu pada sistem aksiomatik dan taat azas serta memiliki objek yang abstrak yaitu berupa objek langsung dan objek tak langsung. Matematika merupakan suatu sarana yang dapat menumbuh kembangkan pola pikir logis, sistematis, kritis, objektif, rasional dan taat azas. Secara umum pekerjaan dalam matematika adalah menunjukkan dan membuktikan suatu kebenaran. Dengan keabstrakan objek dalam matematika, maka suatu hal yang wajar apabila dalam memahami suatu konsep dalam matematika akan memerlukan suatu analisis yang lebih dibanding dengan ilmu lain, dan kerap sekali siswa akan menemui kesulitan.

Mengembangkan Strategi Dan Kemampuan Siswa Memecahkan Masalah Matematik, E Elvis Napitupulu

PYTHAGORAS : Jurnal Matematika dan Pendidikan Matematika

Pemecahan masalah menempati posisi sentral dan merupakan satu bentuk belajar terpenting dalam matematika. Untuk memecahkan masalah, dituntut kemampuan anak memilih dan menerapkan strategi yang sesuai, menggunakan pengetahuan siapnya, di samping memanfaatkan pengalaman memecahkan masalah sebelumnya. Namun fakta di lapangan menunjukkan kemampuan pemecahan masalah di seluruh jenjang sekolah di Indonesia masih rendah. Guru sebagai pengajar dan instruktur di kelas punya kesempatan untuk dapat meningkatkan kemampuan pemecahan masalah anak. Kemampuan itu dapat berkembang bila anak melihat bagaimana berbagai masalah dipecahkan dengan beragam strategi dan dan diberi pula kesempatan memecahkan bermacam masalah sambil membangun pengetahuan baru baginya.

Are The Math Scores Of Students Who Are Taught Mathematics Utilizing The Methods Endorsed By The Alabama Math, Science, And Technology Initiative Affected?, Brenda Elise Jolly

Dissertations

Eighth-grade mathematics scores from 21 schools were compared pre-inception and post-inception of the Alabama Mathematics, Science, and Technology Initiative (AMSTI). Only the scores from schools which had 80% of their mathematics and science teachers trained at one Summer Institute were used, as these were considered to be true AMSTI schools. Results found the effects of AMSTI to be not statistically significant.

The second part of this research was conducted based upon 256 surveys from teachers attending their second Summer Institute of ASMTI training. Results found many school systems may hamper teachers' ability to plan and execute AMSTI lessons due to …

Block Scheduling In High School Mathematics: Effect On Algebra Ii End-Of-Course Grades And Act Assessment Mathematics Scores, Gayle Hawkins Hughes

Doctoral Dissertations and Projects

The purpose of this study was to determine if there was a statistical difference between end-of-course grades in Algebra II at three high schools in northeast Tennessee and mathematics content scores on the ACT Assessment at the same three high schools, by comparing a one-semester accelerated (4x4) block schedule, a two-semester accelerated (4x4) block schedule, and a traditional year-long schedule. The purpose was also to determine if a relationship exists between Algebra II grades and ACT Assessment mathematics content scores for all students and for each school, and to determine if a statistically significant difference occurred in the number of …

Computing For The Masses: Extending The Computer Science Curriculum With Information Technology Literacy, Jorge Pérez, Meg C. Murray

Faculty Articles

Enrollments in computer science programs continue to drop as demand for workers skilled in computing increases. Information technology scholars face the ironic challenge of attracting more students into computing disciplines in the age of ubiquitous computing. This paper chronicles a decision by a department of computer science and information systems to offer an information technology literacy course as a service to its institution. Educational and curricular justifications for the course progressed in parallel with recognition of the course's strategic value to the department in the face of sharp declines in the number of students majoring in CS or IS.

Transforming Teachers’ Knowledge And Skills: Lesson Study In Mathematics Instruction Sensitive For Diverse Learners At Middle Level, Vessela Ilieva

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study investigated the learning of middle school mathematics teachers as they worked in a student-sensitive lesson study group. Three mathematics teachers collaborated to develop and teach student-sensitive math lessons. The original Japanese lesson study model was extended to involve a diversity consultant with experience and expertise in providing student-sensitive instruction. Collaboratively, the members of the lesson study group tailored their mathematics lessons to provide enhanced mathematics instruction to the diverse groups of students in their classrooms. The lesson study team held weekly meetings to develop three student-sensitive lessons over a six-month period.
