This research reports the implementation of an evaluation instrument of the slope concept in high school students. The design of this study was based on four dimensions: Skills, Properties, Uses and Representations (SPUR model; Thompson & Kaur, 2011) and on three conceptualizations: constant ratio, behavior indicator and trigonometric…

Background: 'Learning to Learn' (L2L) is considered a key skill for the twenty-first century. It is understood here as a hyper-competence, which mobilises resources of the individual and/or groups in a sense-making effort to improve or update one's own learning. By means of classroom assessment during the teaching-learning cycle, teachers can…

There are different strategies to analyze teacher and student performance when they interact with each other in class. The most used strategies are direct observation and verbal reports. Even though what is observed or reported depends on theoretical frameworks regarding didactic interactions, these must be related to teacher functions such as…

This mixed methods study examines how secondary school teachers have implemented educational reforms in Mexico.

Results from open-ended questions and classroom observations were used to triangulate results…

This qualitative research addresses the gap of studying the relationship between beliefs about assessment in mathematics and mathematics beliefs by identifying the (espoused) beliefs about assessment and their connections with the mathematical beliefs of 18 high school Mexican out-of-field mathematics teachers (i.e. teachers without formal…

In the mathematical literature on analytical geometry, various notions of the conics' eccentricity correspond to different approaches to these curves. After making a comparative analysis of well-known textbooks to determine coincidences and differences between the various concepts of eccentricity, as well as how the authors explain the…

A mathematical client-driven task known as Model-Eliciting Activities was implemented with students of different levels of achievement (i.e., low, average, and high) at the high-school level. The study strived to prove that Model-Eliciting Activities can be solved by students at any achievement level and be used as an assessment tool. Students…

The present action-research study analyzes students' basic perceptions about the use of the Flipped Classroom as part of their EFL class in a Mexican technical high school.

This article analyzes the knowledge and attitudes of high school students regarding the temperate mountain forest of La Malinche National Park, Tlaxcala, Mexico, before and after the implementation of the science communication program called "Los Tesoros de La Malinche" (The Treasures of La Malinche). The assessment included drawings,…

A characterization of the teaching of three chemistry professors was carried out using a case study with a phenomenographic approach to explore chemistry teachers' general pedagogical knowledge (GPK) through teachers' self-reflection. A video stimulated recall technique was used to identify and examine teachers' thoughts and decisions, as well as…

Widespread school closures affected over one billion students during the first year of the COVID-19 pandemic. The vocational education and training (VET) sector has faced particular challenges during the crisis, most notably the fact that the digital learning environments that most education institutions had to rely on during closures don't work…

This paper studies the impact of PROBEMS, a scholarship program in Mexico aimed at improving graduation rates and test scores among upper secondary school students from poor backgrounds. The identification strategy is the random allocation into the program, which took place in 2009. The strategy allows measurement of the effects of PROBEMS on test…

This report uses the most recent Organisation for Economic Cooperation and Development (OECD) data, primarily from the Programme for International Student Assessment (PISA) 2015 and Teaching and Learning International Survey (TALIS) 2013 cycles, and seeks to evaluate the Ibero-American, countries where Spanish or Portuguese are the predominant…

This Note provides an analysis of Mexico's "Telesecundaria" program within the context of Mexico's new education reform framework offering a succinct background of the project, as well as key policy lessons that can be useful for other jurisdictions interested in the development of distance education programs. This Note uses a literature…
