FALSAFAH PENDIDIKAN KEBANGSAAN

Pendidikan di Malaysia adalah suatu usaha berterusan ke arah lebih memperkembangkan potensi individu secara menyeluruh dan

bersepadu untuk melahirkan insan yang seimbang dan harmonis dari segi intelek, rohani, emosi dan jasmani, berdasarkan

kepercayaan dan kepatuhan kepada Tuhan. Usaha ini adalah bertujuan untuk melahirkan warganegara Malaysia yang berilmu

pengetahuan, berketerampilan, berakhlak mulia, bertanggungjawab dan berkeupayaan mencapai kesejahteraan diri serta

memberikan sumbangan terhadap keharmonian dan kemakmuran keluarga, masyarakat dan negara.



1.0 PENDAHULUAN

Mesyuarat Jawatankuasa Perancangan Pendidikan (JPP) Bil. 195/2010 bertarikh 20 Disember 2010 yang dipengerusikan oleh Menteri Pelajaran telah meluluskan TIGA (3) perkara iaitu program penjenamaan semula Sekolah Menengah Vokasional kepada Kolej Vokasional, menambah baik kurikulum sedia ada dan memperkenalkan kurikulum bidang mengikut keperluan negara.

Mesyuarat Jawatankuasa Kurikulum Pusat Bil. 2/2011 yang dipengerusikan oleh Ketua Pengarah Pelajaran Malaysia pada Jun 2011 telah meluluskan kertas cadangan berkaitan Pentaksiran Berasaskan Standard Kompetensi Vokasional yang merupakan satu kaedah untuk mengukur pelbagai kompetensi vokasional sebagaimana yang ditetapkan oleh Kurikulum Kolej Vokasional.

Pada 31 Jan. 2012, Lembaga Peperiksaan telah menerima kurikulum 16 kursus Kolej Vokasional Rintis hingga Tahap 3 atau 4 yang sedang dilaksanakan pada tahun 2012 di lima belas (15) buah Kolej Vokasional Rintis dari Bahagian Pendidikan Teknik dan Vokasional, Kementerian Pelajaran Malaysia (KPM).

Pentaksiran di Kolej Vokasiona telah direkabentuk dan dilaksanakan secara Pentaksiran Berasaskan Sekolah (PBS) dalam dua bentuk iaitu Pentaksiran Sekolah (PS) dan PentaksiranPusat (PP). PS dijalankan secara formatif seiring dengan proses pengajaran dan pembelajaran. PP pula dijalankan pada minggu peperiksaan yang ditetapkan oleh kolej menggunakan instrument dan peraturan penskoran yang disediakan oleh Lembaga Peperiksaan (LP).

Dokumen Pentaksiran Standard Kompetensi(DPSK) dan Dokumen Item Contoh (DIC) yang dikeluarkanoleh LP dijadikan sebagai panduan untuk guru membimbing dan mendapatkan maklumat tahap penguasaan kompetensi serta keberkesanan pengajaran dan pembelajaran dalam pembangunan modal insane selaras dengan hasrat Falsafah Pendidikan Kebangsaan dan Objektif Kolej Vokasional untuk melahirkan murid berkompetensi pekerjaan aras tinggi dan menepati kehendak industry serta berkompetensi usahawan.
