Penelitian ini bertujuan untuk “Mengembangkan Media Pembelajaran Power Point Macro Berbasis Problem Based Laerning pada Materi Besaran dan Pengukuran Sebagai Sumber Belajar Siswa Kelas X”. Masalah dalam penelitian ini 1) Bagaimana  cara mengembangkan media pembelajaran power point macro berbasis problem based laerning pada materi besaran dan pengukuran sebagai sumber belajar siswa kelas X?, 2) Bagaimanakah karakteristik media pembelajaran power point macro berbasis problem based laerning yang dikembangkan memenuhi sasaran kevalidan dan kepraktisan?, 3) Bagaimanakah respon siswa selama pembelajaran menggunakan media pembelajaran power point macro berbasis problem based laerning?. Model pengembangan yang digunakan yaitu Borg and Gall. Yang terdapat 10 tahapan yaitu: tahap potensi dan masalah, pengumpulan data, desain produk, validasi desain, revisi desain, uji coba produk, revisi produk, uji coba pemakaian, revisi produk dan produksi massal. Subjek penelitian kelas X MIPA SMA AL-IKHLAS Lubuklinggau dengan teknik purposive sampling. Pengumpulan data dilakukan dengan teknik observasi, wawancara, dan angket. Validasi yang dilakukan mendapatkan hasil dengan kategori sangat baik dengan skor 128. İnstrumentasi yang digunakan untuk menguku respon siswa menggunakan angket. Respon siswa kelompok terbatas dan guru mendapatkan skor 146 dalam kategori sangat setuju..Respon kelompok main field testing dengan mengerjakan soal quis 6 siswa tuntas berdasarkan KKM. Untuk angket respon siswa kelompok main field testing mendapatkan skor 312 dalam kategori sangat setuju. Sehingga dapat dikatakan bahwa media pembelajaran power point macro berbasis problem based laerning yang dikembangkan telah valid dan praktis.

The purpose of this study was to develop evaluation tools in the form of learning about science literacy based biology subjects for class X semester 1. The type of this research is research and development, with a preparatory study design, prototype, one to one, small group and field tests. Small scale pilot study subjects were 20 students of SMAN 1 Bukit Sundi, and wide-scale trials were 64 students of SMAN 1 Gunung Talang. Product-based research is a matter of scientific literacy that includes three indicators of votes with four component aspects that owned the aspect of the context, content, processes and attitudes. The results of scientific literacy progression based this matter indicates that the matter developed valid, reliable and high level of practicality. This is demonstrated by the average validity showed extremely valid criteria. The effectivity of instruments is indicated by the student's ability to answer questions on indicators 2 and 3 which is a matter that demands high reasoning. Practicality instruments indicated by the positive response by teachers and students.

Dyslexia is a disorder of the nervous system that is characterized by difficulty recognizing words both reading, spelling, understanding symbols and distinguishing letters. Dyslexic children experience barriers to cognitive development. Children tend to be slow in thinking and hard to understand things like counting, analyzing and understanding words. Some factors that cause children to experience dyslexia are educational, psychological and biological factors. But the main thing is neubiological factors or the brain. This is due to poor connectivity in the function of parts of the brain, namely the brocas, frontal lobe and cortex. Therefore parents or teachers need to implement appropriate strategies or handling methods so that the child's cognitive abilities can develop properly.
