Art history has its own demands for recording visual representations. Objectivity and authenticity are the twin pillars of recording artistic data. As such, techniques relevant to epigraphic study, such as making line drawings, may not always be the best approach to an art historical study, which addresses, for example, questions about natural context and materiality of the artwork, the semantic, syntactic, and chronological relation between image and text, work procedures, work zones, and workshop traditions, and interactions with formal structures and beholders. Issues critical to collecting data for an art historical analysis include recording all relevant information without overcrowding the data set, creating neutral (i.e., not subjective) photographic images, collecting accurate color data, and, most critically, firsthand empirical study of the original artwork. A call for greater communication in Egyptology between epigraphy/palaeography and art history is reinforced by drawing attention to images as tools of communication and the close connection between the written word and figural art in ancient Egypt.

Grade 8

This study is aimed at exploring how different formulations of the same mathematical item may influence students’ answers, and whether or not boys and girls are equally affected by differences in presentation. An experimental design was employed: the same stem-items (i.e., items with the same mathematical content and question intent) were formulated differently and administered to a probability sample of 1647 students (grade 8). All the achievement tests were anchored via a set of common items. Students’ answers, equated and then analysed using the Rasch model, confirmed that different formulations affect students’ performances and thus the psychometric functionality of items, with discernible differences according to gender. In particular, we explored students’ sensitivity to the effect of a typical misconception about multiplication with decimal numbers (often called “multiplication makes bigger”) and tested the hypothesis that girls are more prone than boys to be negatively affected by misconception.

Reasoning By Analogy

This paper first discusses the genetic approach and the relevance of the history of mathematics for teaching, reasoning by analogy, and the role of constructive defining in the creation of new mathematical content. It then uses constructive defining to generate a new generalization of the Nagel line of a triangle to polygons circumscribed around a circle, based on an analogy between the Nagel line and the Euler line of a triangle.

Teaching and learning standards across the country are becoming more content driven, especially in mathematics.  As such, it is essential to develop substantive college level math courses for pre-service and in-service teachers.  These courses should deliver mathematical content in a relevant way.  Teachers must not only be proficient in their subject, but also recognize how to apply content meaningfully to student’s lives.  As part of a grant funded through the Department of Education in coordination with the Clark County School District, I have designed two college level courses that will deliver mathematical content standards to middle school teachers.  These courses will help prepare teachers at the middle school level by focusing on mathematical content, making connections within the curriculum, using technology, and enhancing the role of mathematics in everyday life and problem solving. The primary purpose of this paper is to share with the academic community the projects used to develop content understanding in mathematics topics such as:  mathematical notation, proportion, computation, estimation, linear regression, reflections, translations, finding relationships, and analyzing data.  This paper will present these projects, and tie them to mathematics standards outlined in the Clark County School District (and Nevada State) Standards.

ResumoA resolução de problemas, quando trabalhada com o problema como ponto de partida, tem apresentado profícuas possibilidades no ensino superior. No entanto, quais as possíveis fragilidades quando se trabalha com esta abordagem nesta perspectiva? À vista disso, este artigo apresenta o resultado de uma pesquisa que tem como objetivo desvelar as fragilidades que se evidenciam a partir do desenvolvimento da abordagem de resolução de problemas, em que se tem o problema como ponto de partida na formação inicial de professores de Matemática, apresentadas em teses e dissertações. A partir de uma revisão sistemática da literatura, encontramos 12 pesquisas que constituíram o corpus de dados, para serem analisadas seguindo as técnicas de Análise de Conteúdo, de onde foi possível identificarmos quatro categorias. Os principais resultados revelam que as fragilidades se relacionam com: I) dificuldades quanto à falta de conhecimento sobre o conteúdo matemático da educação básica pelos licenciandos; II) dificuldades apresentadas pelos licenciandos em comunicar suas ideias a respeito do conteúdo matemático trabalhado; III) dificuldade no entendimento dos problemas pelos estudantes; e, IV) dificuldades relativas ao tempo, referentes à realização das atividades pelos licenciandos e ao desenvolvimento da abordagem de ensino. Tais apontamentos podem contribuir com pesquisas futuras que desejem traçar este caminho, aprimorando-as e contribuindo com o processo de ensino e aprendizagem da Matemática.Palavras-chave: Solução de problemas, Formação inicial de professores, Matemática.AbstractWhen working with the problem as a starting point, problem-solving has presented fruitful possibilities in Higher Education. However, what are the possible weaknesses when working with this approach from this perspective? In view of this, this article presents the result of research that aims to unveil the fragilities that are evident from the development of the problem-solving approach, in which the problem is taken as a starting point in the initial training of mathematics teachers, presented in theses and dissertations. From a systematic review of the literature, we found 12 surveys that constituted the corpus of data, to be analyzed following the Content Analysis techniques, from which it was possible to identify four categories. The main results reveal that the weaknesses are related to I) difficulties related to the students’ lack of knowledge about the mathematical content of basic education; II) students’ difficulties to communicate their ideas about the mathematical content worked; III) students’ difficulty in understanding the problems; and, IV) difficulties related to time, concerning the students’ activity performance and the development of the teaching approach. Such notes can contribute to future research that wishes to follow this path, improving them and contributing to the process of teaching and learning Mathematics.Keywords: Problem-solving, Initial teacher education, Mathematics.ResumenLa resolución de problemas cuando se trabaja con el problema como punto de partida, ha presentado posibilidades fructíferas en la educación superior.
