This article reports on the evolution of a STEAM-based teacher professional learning program designed to focus on maker pedagogies. Design-Based Research methodology was used to frame three iterations of professional learning sessions, which collectively involved more than 85 teachers in Ontario, Canada. The article describes the three iterations of teacher professional learning related to a maker approach, reports on what we learned from each iteration and how we modified the pedagogical approach based on the findings, and includes discussion on the implications for future professional learning in maker education.

This book is an expanded version of a guide originally written by the lead author, Matt Crosslin, to serve as a resource for faculty. The book shares lessons learned as the author designed Massive Open Online Courses (MOOCs) and other online courses for the now defunct LINK Research Lab at University of Texas Arlington. At the time of writing the book, Crosslin worked as a Learning Innovation Researcher at the LINK Lab. This expanded version of the book is an Open Educational Resource (OER) (also available in print) with contributions from other authors or contributors that bring diverse perspectives to reach a wider audience. The information and advice in this book is firmly rooted in the experiences of the contributors developing successful online courses, and the ultimate goal is to “provide clarity about many of the steps required to propose and design a course, describe the resources needed, and to explain the roles of stakeholders” (p.1).
这本书是一本指南的扩展版，最初由主要作者马特·克罗斯林(Matt Crosslin)撰写，作为教师的资源。这本书分享了作者为德克萨斯大学阿灵顿分校(University of Texas Arlington)现已倒闭的LINK研究实验室设计大规模开放在线课程(MOOCs)和其他在线课程时的经验教训。在写这本书的时候，克罗斯林在LINK实验室担任学习创新研究员。这本书的扩展版本是一个开放教育资源(OER)(也有印刷版)，其中有其他作者或贡献者的贡献，带来了不同的观点，以达到更广泛的受众。本书中的信息和建议牢牢植根于贡献者开发成功在线课程的经验，其最终目标是“明确提出和设计课程所需的许多步骤，描述所需的资源，并解释利益相关者的角色”(第1页)。

Dans cet article, nous présentons les résultats d’une étude sur l’effet d’un didacticiel que nous avons développé en nous inspirant des stratégies du modèle de motivation ARCS de Keller et destiné à l’apprentissage du langage SQL. Cette étude a concerné 92 étudiants de filières non informatiques répartis en deux groupes : un groupe expérimental ayant suivi l’enseignement du langage SQL en ayant recours au didacticiel que nous avons nommé SQLAlgebraCourse et un groupe contrôle qui n’a pas eu recours au didacticiel. Les résultats de cette étude ont montré que les étudiants du groupe expérimental ont eu un rendement meilleur et ont été, pour la plupart, satisfaits des avantages procurés par l’utilisation du didacticiel.

The present study examined the impact of professional development training on Canadian and Kenyan teachers’ confidence, comfort, and perceptions of their abilities to teach early literacy skills in the primary or elementary grades. Data were collected prior to and following training on how to integrate early literacy software as part of ongoing in-class instruction. Domain and technology constructs consistent with Mishra and Koehler’s (2006) technology integration model were assessed, as were perceptions related to delivery pacing. Overall, outcomes reflected more similarities than differences across the two groups of teachers. Limitations in foundational knowledge regarding concepts specific to early literacy were evident in both groups, despite higher levels of perceived confidence in Kenyan teachers compared to Canadian teachers in some content areas. Perceived comfort using technology and teaching with technology were highly correlated, with no differences observed across teacher groups. Pacing was perceived to be faster for Kenyan teachers compared to Canadian teachers. Implications for professional development in this domain are discussed.

The Knowledge Building International Project (KBIP), implemented in a network of eight schools in Catalonia, demonstrates the value of an Innovative Learning Environment (ILE) towards supporting dialogical, technological, and systemic dimensions in teaching and learning. Using a design-based research (DBR) approach, a survey queried teachers, students, and external stakeholders regarding their perceptions about educational innovation. The results provide both the profile and the innovative nature of the whole KBIP experience at each participating school. The main results help illustrate the potential of KBIP methodologies. The findings exemplify the value of this particular DBR method for evaluating educational innovations.

The aim of this quantitative research is to analyze the impact of Facebook in the teaching-learning process in financial mathematics education, using data science, machine learning, and neural networks. The sample is composed of 46 students from the Bachelor of Administration, Commerce and Marketing program at La Salle University. The results of machine learning (linear regression) indicate that sending messages, watching instructional videos, and publishing exercises on Facebook supports the teaching-learning process in financial mathematics. Likewise, data science identified six predictive models for the use of Facebook in the educational context, by means of the decision tree technique. Analysis using neural networks identified the influence of sending messages, watching instructional videos, and publishing exercises on Facebook during the assimilation of knowledge and development of mathematical skills. Finally, Facebook is a technological and communication tool that transforms the organization of teaching and learning activities in financial mathematics education.

Cette étude pilote a pour objectif de construire une nouvelle épreuve informatisée d’évaluation du vocabulaire en langue Française, destinée aux élèves de primaire. Des tâches à choix multiples mesurant l’étendue (i.e., Image) et la profondeur du vocabulaire (i.e., Synonyme, Définition) ont été administrées à 255 enfants. La rapidité et l’exactitude des réponses ont été enregistrées. Comme attendu, les analyses ont révélé que le niveau scolaire, le genre, et la fréquence lexicale des items impactaient les temps de réponse et/ou réponses correctes. Les performances s’améliorent avec le niveau scolaire et pour les mots fréquents. Les filles semblent avoir un vocabulaire plus riche que celui des garçons (e.g., profondeur) et elles semblent moins sensibles à la fréquence des mots que les garçons. Une analyse des qualités psychométriques de l’épreuve a permis de retenir une épreuve en 36 items ayant une consistance interne satisfaisante. Enfin, une analyse factorielle confirmatoire n’a pas permis de mettre en évidence une structure en deux facteurs du vocabulaire (e.g., profondeur, étendue). Les résultats sont discutés en termes de qualité de représentations lexicales et de choix des tâches.

This paper presents findings from a systematic review of 11 studies examining online teacher professional development (oTPD) in Canada between 2000-2020. A thematic content analysis of the articles led to four main themes associated with research on oTPD: 1. knowledge exchange; 2. reflective practice; 3. multifaceted learning opportunities; and 4. just-in-time support. The study contexts, research methods, and other relevant study characteristics are also reviewed and discussed. The results shed light on the current research trends on oTPD in Canada and highlight the need for continued research in this area. Data from diverse research methods across Canada’s geographical regions can contribute to greater insight into the types of oTPD occurring in Canada and how various platforms and professional development opportunities can best support teachers’ professional learning.

When students learn online, they do so within a wider context of digital disarray, marked by distraction, disorder and disconnection, which research shows to be far from conducive to effective learning. Specific educational issues include a lack of focus, linked to information overload in an environment characterized by misinformation and disinformation, as well as a lack of connection to the self and others. Arguing that today’s growing focus on digital literacies in education already serves as a partial response to digital disarray, this evidence-based position paper proposes the concept of attentional literacy as a macroliteracy which interweaves elements of now established literacies with the emerging educational discourse of mindfulness. Through attentional literacy, students may gain awareness of how to focus their attention intentionally on the self, the relationship with others, and the informational environment, resulting in a more considered approach to learning coupled with an appreciation of multiple shifting perspectives. Armed with this developing skillset, students stand to benefit more fully from digital educational experiences. Considerations for continuing research in this area include the need to adopt a critical stance on mindfulness, and the need to operationalize attentional literacy for the classroom.
