The Optimum Font Size and Type for Students Aged 9-12 Reading Arabic Characters on Screen: A Case Study
No full textMore and more, interest in the way data is displayed on screen has increased, especially with the increase in the number of people using e-text for learning purposes. So, this requires more focus on factors that affect screen legibility. Text display factors, such as font size, line length and font type, have an impact on reading online. Two font types [Arabic Traditional and Simplified Arabic] in four different sizes [10, 14, 16 and 18] are measured using Arabic text. On-line processes were measured using reading –aloud technique. Accuracy of reading was also measured by the average of errors that students made when reading the text, while reading speed was tested by the time it took students to read the text. However, results indicated that Arabic text in font size 10 is not readable to students aged 10 to 12. On the other hand, font sizes sixteen and eighteen are more readable than any smaller-sized font, the averages of error size 18 improve in all font types, while age has a significant impact on reading speed. Simplified Arabic font is reported as readable to students aged 10-12, especially in sizes 14 and 18
Font tuning : a review and new experimental evidence.
No full textThis paper reflects on the kinds of evidence able to confirm that letter and word identification in reading can be supported by encoding the underlying visual structure of the text, and specifically by deriving structural descriptions for letters. It is proposed that structure-driven processes are intimately linked to the implementation of font-specific rules for translating visual features into elements of a letter’s structural description. Evidence for such font tuning comes from studies exploring the impact of font-mixing on reading fluency, and from studies showing how the benefits of experience with a novel typeface can generalise to letters that have yet to be seen in the typeface. After reviewing this evidence, three new experiments are reported which explore font tuning in the context of the lexical decision task. The time course of font tuning, which is monitored by changing the time interval between successive test stimuli, is shown to be sensitive to the overall probability with which successive stimuli appear in the same typeface. In addition, font tuning is shown to reflect item-by-item fluctuations in this probability. Finally, the effects of font-switching are shown to generalise beyond the particular letters present in the text, and to be confined to 1-back transitions. It is concluded that font tuning reflects the implementation of a set of font-specific translation rules held in working memory, and is moderated by the reader’s implicit knowledge of the constraints present in the sequencing of successive portions of text

Prescribing by mental health nurses: the UK perspective
No full textPURPOSE. This article aims to discuss the growth of mental health nurse (MHN) prescribing in the United Kingdom as an exemplar for readers to compare progress in their own countries and context. This study also aims to provide a historical overview of this process in the United Kingdom where MHNs prescribe safely and competently.
CONCLUSIONS. Finally, evidence has shown that MHNs with prescriptive authority are competent when prescribing when compared to psychiatrists.
PRACTICE IMPLICATIONS. Despite organizational barriers and educational concerns, MHN prescribing is becoming embedded in the healthcare context in the United Kingdo

Primera lliçó: "Escriure per existir"
No full textEn la lliçó de Rosa Font l'escriptora fa una reflexió de la seva trajectòria literària i del que ha estat la creació per a ella.
Escriure li permet endinsar-se en un univers on desapareixen les coordenades espai-temps i viure en un àmbit de plenitud i harmonia. Com l'Alícia a l'altra banda del mirall, ens instal·lem a l'altra banda de les coses, vivim en un altre univers que es construeix amb les paraules per després retornar, contemplar la vida amb els ulls de sorpresa d'un infant.
Si ens poguéssim endinsar en les profunditats de l'inconscient , què hi trobaríem, es pregunta l'autora del Premi Nobel de Literatura, Han Kang. Abans de l'escriptura hi ha un buit, el no-res, el gran silenci abans del poema. Segons Rosa Font, un poema por sorgir o es pot crear per una imatge, una paraula, una lectura, una visió, una experiència.
Escriure és també mirar, observar i retenir com l'aranya que atrapa la seva presa en una teranyina.
La Poesia és enigma, intuïció, impuls però també és estructura, forma, construcció, és fusió d'innocència i experiència.
Rosa Font comenta que va començar a cantar de ben petita, la poesia és música també.
La poeta ens parla de les seves lectures infantils. El català és la seva llengua d'expressió, era la llengua que li brollava de manera natural.
L'ensenyament i mestratge de Maria Àngels Anglada i les lectures van fer créixer la seva passió per la llengua i la literatuta catalanes, per això va decidir estudiar Filologia Catalana.
Els temes en la poesia de Rosa Font són: la natura, la vida quotidiana i la mirada de l'altre, l'alteritat.
Sempre hi ha hagut una continuïtat en la seva trajectòria poètica, ha estat un camí pausat però constant8178.mp4

Segona lliçó: "Ensenyar i educar: Experiències i reflexions"
No full textRosa Font ens parla en aquesta segona lliçó de la seva trajectòria com a professora d'ensenyament secundari.
En primer lloc ressalta la distinció i del significat dels mots "ensenyar" i "educar".
Rosa Font reflexiona al voltant de l'ensenyament i de la seva experiència en la carrera docent i el que ha après al llarg d'aquests anys com a professora.
Quan la poeta va començar a donar classes la seva tasca era ensenyar, amb el temps ha esdevingut la d'educar en valors, un paper que han de fer les famílies i l'entorn social.
En els temps actuals ensenyar ha esdevingut un repte més difícil perquè hi ha molts factors que conflueixen al professorat a adaptar-se als canvis supersònics que es viuen en la societat actual.
Adquiri valors vol dir esmerçar-hi esforç, sacrifici i avui dia la rapidesa mensyprea la paciència i la perseverança, fins a vegades l'afany i la curiositat, que són fonamentals per a qualsevol classe d'aprenentage. S'ha entronitzat el "carpe diem" com a sinònim de felicitat, com una fórmula gairebé única de viure millor quan en el fons mostra una insatisfacció continuada.
Rosa Font pensa que potser ha hagut un abús de pantalles en les escoles.
Cal establir una diferència entre formació i informació, hi ha un excés d'informació que impedeix l'assimilació i la consolidació de l'aprenentatge.
La gran dificultat d'avui dia és destriar en el missatge el que és veritat del que és fals, com podem saber quina informació és certa de tot el que ens arriba.
Hi ha un creixement del desinterès per esbrinar què hi ha de veritat en una informació, és més fàcil acceptar una informació que es va repetint que no pas preguntar-se si és certa.
Quan Rosa Font va començar a donar classes de català a l'institut de Sant Feliu de Guíxols l'any 1979 no hi ha havia llibres de text en català. Eren els primers a exercir com a professors de català als instituts.
El 1981 es va traslladar a Girona i va començar a donar classes a l'Institut Santiago Sobrequés, intervenint en les múltiples activitats culturals que es es feien en el centre. Va fer també edicions d'obres literàries catalanes i adaptacions, destinades a l'ensenyament i llibres de text de llengua catalana.
El que ha après en tots aquests anys és que educar no és una tasca fàcil, cal tenir una formació àmplia i ganes d'ensenyar; cal buscar la manera de vehicular uns coneixemnets amb mètodes adequats a l'edat dels alumnes i el curs; comporta hores de preparació i de treball individual i en grup de professors. Tots els alumnes tenen un portencial i cal saber-ho descobrir i extreure del seu interior; cal donar sempre una oportunitat als alumnes.
La literatura catalana ha estat la materàia que ha impartir amb més complaença i entusiasme.
Rosa Font conclou en què la literatura també parla de coses que preocupen als alumnes8179.mp4
