In the research on mathematics education, numerous Likert-type instruments estimating attitudes toward mathematics are sometimes composed of factors with a high correlation, which can make it difficult to assign the statements from the scale to each estimated factor. Further, the measurement of attitudes is usually done by adding the scores but ignoring the existence of possible differences in the importance that each item can have in its factor estimation. A revision of the methodology for the study of attitudes toward mathematics for the correct validation of the instrument is carried out in this research, and an estimation of the factors of attitude is proposed using the calculation of the weighted average of scores based on the importance that each item has in the explanation of its factor, which is given by a structural equation model. This methodology has been applied to Auzmendi's scale of attitudes toward mathematics measurement in a sample of 1293 university students. The factors were estimated using simple and weighted averages; significant differences have been obtained in the measurements, as well on those shown with the organization proposed by Auzmendi.

Old mathematics books and textbooks have focused different researchers onto the history of mathematics and mathematics education. However, books are not the only information source for this field; for example, researchers can also study periodical-type publications from the past (such as diaries, weeklies, newspapers, etc.). Considering this, this study developed an instrument to analyze publications about mathematics and mathematics education included in newspapers, weeklies, journals, etc., which were not exclusively devoted to science, from the perspective of the history of mathematics and mathematics education. In order to do so, a descriptive research focused on the analysis of historical texts was carried out using the content analysis technique. The different labels and categories of this instrument are here exemplified by the categorization of some entries included in several periodical publications published in the 18th century in Spain.

In recent years, bibliometric studies on mathematics education have allowed us to learn more about the scientific production in this field. To continue this line of study, in this research we have focused on the doctoral theses published on mathematics education and, in particular, on the role of women in the production, direction and evaluation of doctoral theses in this field, focusing on Andalusian universities. For this purpose, a bibliometric study has been carried out using the Teseo database. The results show a decrease in Andalusian doctoral production in this field in recent years and how, although the number of women who have completed doctoral theses in this field is greater than that of men, in the case of the direction of them, the number of male directors is greater than men directors.

Se presenta un análisis sobre los proyectos de innovación docente en educación primaria que involucran a las matemáticas y que se desarrollan en la Comunidad Autónoma de Andalucía, España. Es un estudio descriptivo y exploratorio sobre una muestra de proyectos depositados en el repositorio del portal Averroes de la Junta de Andalucía. Se halló una gran variedad de objetivos y las metodologías propuestas se agrupan alrededor de tres ejes: el alumno, el rendimiento académico y los procesos.
