DESIGN & VALIDATION METHODOLOGY FROM A LIFE PREDICTION PERSPECTIVE FOR THE STRUCTURAL COMPONENTS OF A RECREATIONAL PRODUCT
The paper outlines a design process flow diagram (methodology) that highlights the challenges of engineering design and allows both engineers and students to focus on the development of a creative, effective and profitable solution to meet particular life objective and additional criteria. A case study related to a recreational vehicle is also presented to validate the methodology. Therefore, to reach the objective of weight reduction for the structural subsystem in a hybrid roadster project, a methodology that allows the optimization of the design parameters according to several types of design criteria has been developed
Validation et consistance interne dâune batterie de tests pour lâĂ©valuation multidimensionnelle de la lecture en français
Nous prĂ©sentons les considĂ©rations thĂ©oriques qui guident lâĂ©laboration de la batterie de tests destinĂ©e Ă lâĂ©valuation de la lecture en français. Ensuite, nous Ă©tayons les cinq domaines ciblĂ©s par la Batterie dâĂ©preuves multidimensionnelles pour lâĂ©valuation de la lecture (BĂMĂL) : a) la sensibilitĂ© phonologique, b) les connaissances alphabĂ©tiques, c) lâidentification des mots rĂ©els ou inventĂ©s, d) la sensibilitĂ© grammaticale, e) la comprĂ©hension des phrases et des textes. Nous rapportons les rĂ©sultats dâune Ă©tude sur huit Ă©chelles de mesure reprĂ©sentant trois de ces domaines. Ces rĂ©sultats attestent que la consistance interne des Ă©chelles est satisfaisante et que lâaugmentation de la performance en fonction du niveau scolaire appuie la validitĂ© des concepts reprĂ©sentĂ©s par ces Ă©chelles. Nous concluons avec quelques observations sur le dĂ©veloppement Ă venir.The authors present the theoretical underpinnings used in the development of a battery of tests to evaluate reading in French. The five areas targeted by the âBatterie dâĂ©preuves multidimensionnelles pour lâĂ©valuation de la lectureâ (BĂMĂL) include: a) phonologic sensitivity, b) alphabet knowledge, c) identification of real and invented words, d) grammatical awareness, e) comprehension of sentences and text. Presented are the results of a study of eight measurement scales representing three of these areas. The results show that the internal reliability of these scales is satisfactory and that the improvement in performance at each school level supports the validity of the concepts represented by these scales. The authors conclude with several observations regarding future development.Presentamos las consideraciones teĂłricas que orientan la elaboraciĂłn de la baterĂa de tests que tiene por objetivo la evaluaciĂłn de la lectura en francĂ©s. A continuaciĂłn apuntalamos los cinco dominios enfocados para la BaterĂa de pruebas multidimensionales para la evaluaciĂłn de la lectura (BEMEL): a) la sensibilidad fonolĂłgica, b) los conocimientos alfabĂ©ticos, c) la identificaciĂłn de las palabras reales o inventadas, d) la sensibilidad gramatical, e) la comprensiĂłn de las frases y de textos. Informamos de los resultados de un estudio basado en ocho escalas de medida que representan tres de estos dominios. Estos resultados confirman que la consistencia interna de las escalas es satisfactoria y que el incremento del rendimiento segĂșn el nivel escolar sostiene la validez de los conceptos representados por estas escalas.

The impact of a computer based adult literacy program on literacy and numeracy : evidence from India
With over 700 million illiterate adults in the world, many governments have implemented adult literacy programs across the world, although typically with low rates of success partly because the quality of teaching is low. One solution may lie in the standardization of teaching provided by computer-aided instruction. We present the first rigorous evidence of the effectiveness of a computer-based adult literacy program. A randomized control trial study of TARA Akshar Plus, an Indian adult literacy program, was implemented in the state of Uttar Pradesh in India. We find large, significant impacts of this computer-aided program on literacy and numeracy outcomes. We compare the improvement in learning to that of other traditional adult literacy programs and conclude that TARA Akshar Plus is effective in increasing literacy and numeracy for illiterate adult women
SOURCES DE MATĂRIEL EN FRANĂAIS POUR LâĂLABORATION DâĂPREUVES DE COMPĂTENCES EN LECTURE ET EN ĂCRITURE
LâĂ©laboration dâune Ă©preuve de competences en lecture ou en Ă©criture prĂ©sente de nombreux dĂ©fis. On doit assurer la reprĂ©sentativitĂ© des items par rapport au concept ciblĂ© et prendre en compte les variables linguistiques susceptibles dâinfluencer le comportement mesurĂ©. Les informations afferents Ă ces variables linguistiques proviennent typiquement des dictionnaires spĂ©cialises ou des etudes normatives sur la langue. Le but du present article est de rapporter les rĂ©sultats dâune recension systĂ©matique des sources de materiel en français pouvant server Ă lâĂ©laboration dâĂ©preuves de competences en lecture et en Ă©criture. Ce compte rendu est organize selon une taxinomie hiĂ©rarchique dans laquelle nous opĂ©rons une diffĂ©renciation progressive entre les unites segmentales de la langue, des unites supralexicales aux unites infralexicales. Les variables pertinentes sont dĂ©finies et les sources de matĂ©riels ou de donnĂ©es normatives sont prĂ©sentĂ©es. Mots clĂ©s : Ă©valuation des compĂ©tences en lecture et en Ă©criture, ressources pour la construction des Ă©preuves en français, donnĂ©es normatives sur le lexique du français The development of tests for the assessment of reading or writing skills always is a challenging task. A representative sample of items for the theoretical construct of interest must be selected and the linguistic variables likely to influence the behavior being measured must be taken into account. The most useful information for this purpose is found in specialized dictionaries and normative data studies. The goal of the present article is to systematically review the sources of material in French that can serve in the assessment of reading and writing skills. This review is broken down into the segmental units of the French language, from supraâlexical to subâlexical units. The relevant variables are defined and the sources of material and normative data are presented.Key words: assessment of reading and writing skills, resources for test construction in French, normative data on the French lexicon
The impact of a computer-based adult literacy program on literacy and numeracy: Evidence from India
With over 700 million illiterate adults worldwide, governments in many developing countries have implemented adult literacy programs. Typically these programs have low rates of success partly because the quality of teaching is heterogeneous. Standardization of teaching provided by computer-aided instruction might be a solution. However, there is little rigorous evidence of the effectiveness of computer-based adult literacy programs in delivering high-quality literacy and numeracy in the developing world. To fill this void in the literature, we study the impact of a computer-based adult literacy program, Tara Akshar Plus, on the literacy and numeracy skills of previously illiterate adult women in the north Indian state of Uttar Pradesh. Through a randomized control trial, we measure learning outcomes with individual-level literacy and numeracy tests and find statistically significant positive impacts of this computer-aided program on literacy and numeracy outcomes of women who undergo the TARA Akshar Plus programârelative to the control group. The effects are statistically significant but small in magnitude for women who were entirely illiterate prior to the program. The learning impacts are substantially larger for learners who knew at least a handful of letters at the beginning of the program. We compare the improvement in learning to that of another adult literacy and numeracy program. We conclude that TARA Akshar Plus is the more effective of the two, but the literacy and numeracy level achieved are not large enough to make many entirely illiterate learners become functionally literate
