Are These theOnly Programsfor Treatmentof Reading andLanguageProblems?This matrix of widelyused programs doesnot include all ofthe programs that havebeen proven effectivein remediating readingdisabilities or preventingreading problemsin “at risk”children. Research onearly intervention andprevention of reading disabilities has been conductedwith many other instructional materials and programsthat are not included in the matrix (see references).Additional reviews of instructional and interventionprograms can be found on the website of the FloridaCenter for Reading Research (www.fcrr.org).Are These Programs Research-Basedor Evidence-Based?What Program CharacteristicsAre Most Important?Intervention and remediation researchers report overand over that the most effective programs ofinstruction, at all ages, explicitly address multiplecomponents of oral and written language learningin an integrated manner. These components include:phonological awareness; vocabulary development;reading comprehension skills and strategies;beginning and advanced decoding skills, with spellingincluded; reading fluency; handwriting; grammar;written composition; and strategies for learning.Certain programs that have been validated by researchtarget some of these components, but the strongestcontain lesson formats in which these components areinterrelated and taught in parallel strands. In additionto teaching the content strands, effective approachesare explicit, systematic, multisensory, and cumulative.Interested consumers should contact programwebsites or program offices for specificinformation on research supporting the approach,and for other key information. Many of theseprograms provide websites, videos or DVDsexplaining their unique characteristics.The best studies of program effectiveness reportthe characteristics of the students in the study, theduration and intensity of the intervention, the trainingand skill of the teachers, the fidelity of programimplementation, and the exact methods that wereused. They also measure student outcomes multipletimes during intervention with several valid, acceptedassessments. Such research is expensive and complex,and many effective, clinically tested programs existthat have not been included in rigorous comparisonstudies. Some programs in the matrix are in thatcategory. Other programs, not on the matrix, havebeen proven effective for teaching specific skills tocertain kinds of children at particular stages of readingdevelopment, but do not identify themselves as MSLprograms. Each program will provide the existingevidence for effectiveness on request. In summary, theeffectiveness of some of the programs on the matrixis established by scientific standards, and theeffectiveness of others is established through clinicaluse over time. The matrix does not include allprograms with demonstrated effectiveness.

Industrial Air Curtain1.3 About the unit1.3.1 ApplicationsThe air curtain model IndAC is designed toseparate the indoor and outdoor climates orthe climates in two rooms. It is installedabove or next to the door, across the fullwidth or length of the doorway. The IndACmodel is particularly suitable for larger doorsin industrial buildings.Depending on the type, the air curtain iseither hung horizontally above the doorwayor installed vertically next to the doorway (tothe left or right or on both sides).1.3.2 Principle of operation1 IntroductionThe air curtain draws air from the room andblows it, either heated or not, as a directionalair stream across the doorway.The air curtain reduces the undesired effectsof an open door by either reducing the exchangeof air between two rooms or heatingthe entering air, or by combining these twofeatures.1.3.3 Type designation, unitThe type designations, when combined,constitute the type code for the relevant unit,for instance:IndAC S-150-W1-0IndAC M-200-E-1LIndAC L-225-A-2RVarious combinations can be made.Explanation of type code of unitSeries IndAC Industrial AirCurtainRangeS, M, L, XLUnit Size 150, 200, 225 air dischargelength (in cm)Example of a horizontal installationHeatingW1, W2, W3 hot waterEelectricInstallationPositionA01L, 1R2L, 2Rwithout heating(Ambient)See section1.3.4.Example of a vertical installationVersion 2.1, English (27-10-2008) 5
