Challenges and Opportunities in IXP Evolution towards SDN
Serbian Open eXchange (SOX) has embraced the logical direction of future growth by transitioning towards SDN-ready networks. However, various challenges like lack of best practices, expertise, and tested features hinder the smooth migration to full SDN environments. Despite these obstacles, implementing SDN in IXP environments offers benefits like improved link protection and load balancing. The shift to SDN requires careful consideration of high-capacity switches, migration costs, and the need for continuous service expansion during the transition.

AN INTRODUCTION TO DYSLEXIA
WHAT DO I KNOW ABOUT DYSLEXIA?
Myths vs. Reality
Dyslexia is rare. ~ Dyslexia impacts 5% to 17% of the population. Dyslexia is a visual problem. People with dyslexia see things backwards. ~ Dyslexia is a language-based problem, not a visual problem. Everyone who struggles to read is dyslexic. ~ A hyperlexic can read words accurately and fluently, but struggles with comprehension. Reversals are a core feature of dyslexia. ~ Reversals are seen in any individual with low literacy. People who are dyslexic are unable to read. ~ Individuals who receive systematic, explicit instruction can learn to read. Dyslexia is outgrown. ~ They just need more time is one of the most harmful myths. Time to mature doesn t fix the problem.
Dyslexia cannot be diagnosed until 3rd grade. ~ Research indicates dyslexia can be successfully identified as early as the age of 5. Dyslexia is a medical diagnosis. ~ Dyslexia is an educational determination made by assessing reading, spelling, and phonological awareness. There is a test for dyslexia. ~ Dyslexia identification is a process that includes assessments and monitoring how the student responds to instruction. Individuals with dyslexia are just lazy, they need to work harder. ~ Individuals with dyslexia are working harder and often become fatigued quickly due to the way the brain tries to process reading the word. Gifted individuals cannot be dyslexic. ~ Twice exceptional means an individual is both gifted and dyslexic. Colored overlays are an effective treatment for dyslexia. ~ A colored overlay will not fix a phonological or word level reading problem.
Current Reality in Arkansas 32% of 4th grade students in Arkansas are proficient in reading (National Assessment of Educational Progress, 2017) 29% of 8th grade students in Arkansas are proficient in reading (National Assessment of Educational Progress, 2017) 40.6% of 3rd-10th grade students are proficient in Reading (ACT Aspire, 2017) 35% of graduating seniors in Arkansas met reading readiness benchmarks (ACT, 2017) Dyslexia impacts about Dyslexia impacts about 1 1 out of every 5 people. out of every 5 people.
1 in 5 of all people worldwide have dyslexia. 8.5 Million American students have dyslexia. 85% of students with Learning Disabilities have dyslexia. Dyslexia runs in families. Dyslexia runs in families. If a child struggles to read, odds are at least one parent will too. Dyslexia is a neurobiological neurobiological brain difference that affects people s ability to manipulate language manipulate language (not a vision problem). Dyslexia never goes away, but people with dyslexia can learn to read if, and often only if, they are taught with Structured Literacy which helps to rewire their brain. People with dyslexia often suffer low self esteem because they feel stupid, struggle in school and are teased. Dyslexia is in no way tied to IQ. In fact, some of our most successful people have dyslexia

Research Based Definition Dyslexia is a specific learning disability that is neurological in origin. It is characterized by difficulties with accurate and/or fluent word recognition and by poor spelling and decoding abilities. These difficulties typically result from a deficit in the phonological component of language that is often unexpected in relation to other cognitive abilities and the provision of effective classroom instruction. Secondary consequences may include problems in reading comprehension and reduced reading experience that can impede the growth of vocabulary and background knowledge. Adopted by the Board of Directors, International Dyslexia Association: November 2002

Phonological Awareness Phonological awareness is the awareness of the sound structure of language deals with the larger chunks of language like words, syllables, and onsets/rimes. Say baseball without the -ball How many syllables are in tricycle
Phonemic Awareness The number one predictor of reading success! Metacognitive appreciation of the explicit sounds (phonemes) in spoken words Demonstrated by listening and - Blending spoken sounds - Segmenting spoken words into sounds - Manipulating spoken sounds Say guide. Now say guide, but change the /g/ to a /r/ ride

What does effective instruction look like?
A MULTI-TIERED SYSTEM OF SUPPORT Teach all students (Tier 1) Reading, Structured Literacy curriculum, which prepares students to decode words in an explicit and systematic manner. (Tier 1) with a Science of Provide targeted Tier 2 explicitly reteach critical concepts in small groups so students develop automaticity. These students get a double dose. students get a double dose. Tier 2 interventions that These When students are not making growth with Tier 1 and Tier 2 instruction, we need to add Tier 3 dyslexia intervention dyslexia intervention instruction to provide intense, small group, targeted intervention. These students get a triple dose These students get a triple dose Tier 3 Tier 3 Tier 3 Tier 2 Tier 2 Tier 2 Tier 2 Tier 1 Tier 1 Tier 1 Tier 1 Tier 1 Tier 1
Interventions must be systematic, cumulative, sequential, multisensory and evidence based. (i.e. Science of Reading) Duration will be based on the intervention program chosen and needs of the student

What does Dyslexia look like in the classroom?
Dyslexia in Secondary students: Struggle with oral language Struggle to find the right word Unable to create a summary Listening vocabulary is higher than spoken vocabulary Often struggle with organization
Adolescents: Hide reading problems Rely on memory Avoid reading, let others read for them May not be able to write, dysgraphia International Dyslexia website- interdys.org
Accommodations and/or Modifications Students may need a ramp to access grade level material while we build up reading skills. The following accommodations may be appropriate. Students must have a 504 plan or an IEP to possible receive these accommodations/modification for state and national testing. Decisions about individual students should be made by the SBIT/504/IEP team. Writing Writing Reading Reading Allow audio books and/or text-to-speech software Utilize outlines, summaries Preview questions and vocabulary Allow peer reading support (discreet and supportive) Grade for content rather than spelling Allow students to dictate work to an adult Substitute alternative projects for written reports Utilize speech-to-text software Reduce written work Minimize copying Accept oral responses, reports, and presentations

Instruction Instruction Break task and directions into small steps Emphasize daily review Provide copy of notes Classroom Classroom Post schedules and maintain routines Chart assignments on a calendar Use color coding to organize materials and information Incorporate multisensory activities Coordinate preferential seating Avoid requiring student to read aloud in front of a group. Testing Testing Provide extra time Review directions orally Read test orally Allow dictated response Homework Homework reduce reading and writing requirements Limit time spent on homework Provide extra time
