This research evaluated (a) the correlation between math anxiety, math attitudes, and achievement in math and (b) comparison among these variables in terms of gender among grade 9 students in a high school located in southern Ontario. Data were compiled from participant responses to the Attitudes Toward Math Inventory (ATMI) and the Math Anxiety Rating Scale for Adolescents (MARS-A), and achievement data were gathered from participants’ grade 9 academic math course marks and the EQAO Grade 9 Assessment of Mathematics. Nonparametric tests were conducted to determine whether there were relationships between the variables and to explore whether gender differences in anxiety, attitudes, and achievement existed for this sample. Results indicated that math anxiety was not related to math achievement but was a strong correlate of attitudes toward math. A strong positive relationship was found between math attitudes and achievement in math. Specifically, self-confidence in math, enjoyment of math, value of math, and motivation were all positive correlates of achievement in math. Also, results for gender comparisons were nonsignificant, indicating that gender differences in math anxiety, math attitudes, and math achievement scores were not prevalent in this group of grade 9 students. Therefore, attitudes toward math were considered to be a stronger predictor of performance than math anxiety or gender for this group.

This project addressed the need for more insightful, current, and applicable resources for intermediate math teachers in Canadian classrooms. A need for a handbook in this division seemed warranted by a lack of government resource support. Throughout an extensive review of the literature, themes and topics for the handbook emerged. The handbook was designed to not only provide educators with examples of effective teaching strategies within the mathematics classroom but to also inform them about the ways in which their personal characteristics and personality type could affect their students and their own pedagogical practices. Three teaching professionals who had each taught in an intermediate math class within the past year evaluated the handbook. The feedback received from these educators was directly applied to the first draft of the handbook in order to make it more accessible and applicable to other math teachers. Although the handbook was written with teachers in mind, the language and format used throughout the manual also make it accessible to parents, tutors, preservice education students, and educational administrators. Essentially, any individual who is hoping to inspire and educate intermediate math students could make use of the content within the handbook.

The hyperfine structure and isotope shift of ^{221- 226}Ra and ^{212, 214}Ra have been measured in the ionic (Ra 11) transition 7s^2 S_{1/2} - 7p ^2 P_{3/2} (\lamda = 381.4 nm). The method of on-line collinear fast-beam laser spectroscopy has been applied using frequency-doubling of cw dye laser radiation in an external ring cavity. The magnetic hyperfine fields are compared with semi-empirical and ab initio calculations. The analysis of the quadrupole splitting by the same method yields the following, improved values of spectroscopic quadrupole moments: Q_s(^221 Ra)= 1.978(7)b, Q_s (^223 Ra)= 1.254(3)b and the reanalyzed values Q_s(^209 Ra) = 0.40(2)b, Q_s(^211 Ra) = 0.48(2)b, Q_s(^227 Ra)= 1.58(3)b, Q_s (^229 Ra) = 3.09(4)b with an additional scaling uncertainty of ±5%. Furthermore, the J-dependence of the isotope shift is analyzed in both Ra II transitions connecting the 7s^2 S_{1/2} ground state with the first excited doublet 7p^ P_{1/2} and 7p^ P_{3/2}.

Juan Luis Arsuaga ha vingut a Girona a parlar de Darwin i de tanta raó com tenia, gairebé en tot. L'ha convidat la Butaca Casademont, el fòrum de debat que impulsa la Fundació que duu el nom del que va ser el primer president del Consell Social de la UdG, Jaume Casademont. Arsuaga es defineix com un estoic pur que creu que no controlem res i que el nostre marge de maniobra és mínim. Davant d'aquesta percepció de la realitat, proposa viure la vida amb dignitat

El objetivo de la presente obra es el de enriquecer a los alumnos y al resto de la comunidad educativa, y transmitirles un mensaje de respeto y comprensión hacia el 'medio'. El Instituto en el que se ha realizado la experiencia está rodeado por: un paredero de ratoneras, una charca en la que anidan ánades reales, garzas, pollas de agua, una cuadra con más de ochenta cabezas de ganado, un vivero de árboles autóctonos, autovías y un aeropuerto, por lo tanto se convierte en un marco idóneo para las actividades propuestas en esta guía. La presente está enfocada a los profesores.

Este trabajo es una recopilaci??n abierta de temas rurales, realizada mediante preguntas y entrevistas a los mayores, padres y abuelos de los pueblos de Cabu??rniga y la creatividad de los alumnos del Colegio 'Manuel LLano' de Ter??n. En el libro se recogen: costumbres, leyendas, tradiciones, formas de vida, citas de escritores cabu??rnigos y dibujos de los ni??os y ni??as del colegio. Se pone ??nfasis en la idoneidad del momento para escribir sobre el pasado, ya que la transformaci??n agraria, el uso de la maquinaria, etc. pone en declive los modos de vida rurales, tareas manuales con utensilios desfasados.
