Purpose: This paper aims to describe the statistical arguments produced by third-grade students (8-9 years old) and to identify the teaching support for collective argumentation in a lesson based on data comparison. A Lesson Study Group researched and planned the lesson around a problem from the official mathematics textbook.…

This qualitative exploratory case study focused on a Professional Development (PD) program for mathematics teachers in the public system, which is an underserved community of teachers in Chile. The study aimed to understand how the program addressed the challenges brought by the pandemic. Using semi-structured interviews and drawing from a…

The decisions that teachers make in transforming the curriculum into specific lesson plans determine the real enactment or otherwise of curricular ideals. These decisions are shaped by the resources available and by each teacher's goals and orientations. This exploratory study employs Schoenfeld's decision-making model to examine how resources,…

Despite the growing use of the Internet as a source of information for learning, few studies have focused on developing strategies to teach the skills of reflecting on and evaluating the contents and structure of the texts found online. In response to this, we designed and tested a method for teaching reading literacy based on an adaptation of the…

The Survey of Adult Skills is a product of the Programme for the International Assessment of Adult Competencies (PIAAC) led by the Organisation for Economic Cooperation and Development (OECD). The Survey of Adult Skills aims to measure the skills needed by adults to participate in society and for economies to prosper. The 2023 survey assessed…

Teachers face situations that are difficult to solve, which affect their practices in the classroom. Teachers' ability to face problematic situations been related to educators' adaptive and metacognitive capacity. This study aimed to contrast the recent literature on classroom problems with reports from Chilean teachers regarding what they mean…

This classroom-based study explored language mindsets in the context of communicative interaction between L2 learners. Amid the increasing research on mindsets in the L2 field, two issues warrant further research to improve our understanding of how mindsets affect L2 learning. First, research has largely been product-oriented and mindsets' impacts…

Background/Context: This article discusses the influence and legacy of three Chilean educators in the country's schooling system during the first half of the 20th century. Focus of Study: Based on the changes that Darío Salas, Irma Salas, and Amanda Labarca promoted in the Latin American country, it explores how the ideas of their teacher John…

In this paper we studied the personal mathematical work of 14 students in initial teacher training, in their first year of studies at a public university in Chile, based on two tasks on complex numbers. These tasks were set in a Computer Aided Assessment System (CAA) based on Moodle and Wiris and it was proposed to solve them using different…

For several decades, scholars have studied the role of cooperation and its outcomes in educational contexts. Yet we lack a complete understanding of how different instructional strategies impact the relationship between cooperation and learning. In this paper we present results from a field experiment with 82 first-year students in an introductory…

Empirical evidence demonstrates the effect of productive failure (Kapur, 2008) on disciplinary knowledge. However, there is no clear theoretical explanation for why this is the case. Empirical evidence on argumentation and education shows the impact of curricular embedded deliberative argumentation on learning. However, these two trends of…

Affect has been identified as one of the important inputs in illuminating the mechanism of cognitive activities in mathematical problem solving (MPS). This study aimed to assess upper primary students' MPS-related affect with a focus on its differences across gender and grade-level among upper primary students. To do so, a simple Likert type scale…

Although feedback is recognized as one of the most relevant factors to improve learning, its effectivity is highly dependent on the specific setting. In particular, feedback in elementary school students has not been thoroughly studied. Within this scope, studying the effectiveness of different degrees and types of feedback for primary school…

In this paper we present a theoretical discussion on how problems issued from discrete mathematics can develop the attitudes, skills, and knowledge required for scientific mathematical activity in the classroom. We do so via the research situation for the classroom model by performing mathematical and didactical analyses of a problem issued from…

In this paper we report on the impact of a year-long teacher professional development (PD) workshop on student problem-solving skills. The PD workshop was held in Chile and promoted the use of collaborative problem-solving activities in the classroom, through monthly sessions during the school year. Participant teachers met with a monitor to solve…
