However, EMS’s work can be impeded if they do not have structured opportunities to collectively grapple with the nuances of terminology included in teaching and learning initiatives in terms of expectations for what practices look like within classrooms. Using narrative data collected from EMS team discussions about the meaning of student engagement in mathematics classrooms, we share a five-phase framework for using a collective doubting process to promote professional learning through the development of shared understanding of common language. By positioning moments of doubt as opportunities for collaborative learning, this framework serves as a flexible structure to guide the development of knowledge-in-practice from the identification of a practice-centered inquiry goal to cohesive understanding and systemic transformation.","PeriodicalId":36817,"journal":{"name":"Investigations in Mathematics Learning","volume":"15 1","pages":"118 - 134"},"PeriodicalIF":0.0,"publicationDate":"2022-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47174723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we examine a coaching routine called Teacher Time Out (TTO), which was organically developed by a school-based mathematics coach and the teachers with whom she worked. Through the routine, coaches and teachers work through complex, in-the-moment pedagogical decision making while collectively facilitating mathematics discussions among students. The routine thus opens opportunities for educators to learn about ambitious teaching alongside their colleagues. We report findings from an analysis of 360 TTOs that occurred over three years of one coach’s work supporting a school-wide, multi-year instructional reform effort in mathematics teaching and learning. We found that the coaching routine fostered teachers’ collective inquiry into practice, as they engaged with the unpredictability of teaching during real-time instruction with students. We discuss the potential of this routine to support coaching as a lever for organizational reform, reshaping mathematics teaching across many classrooms.","PeriodicalId":36817,"journal":{"name":"Investigations in Mathematics Learning","volume":"15 1","pages":"11 - 28"},"PeriodicalIF":0.0,"publicationDate":"2022-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47222512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As such, they are useful frameworks for exploring how understandings of diverse learners may be similar or different from their peers, which has implications for tailoring instruction. The purpose of this teaching experiment was to explore a diverse learner’s understandings about equipartitioning and relational reasoning. Across eleven 45-min individualized sessions, the equipartitioning learning trajectory (EPLT) served as the framework for investigating the student’s thinking and learning. Findings illustrate how a student’s actual trajectory can be focused on developing a many-to-one meaning for fractions and relational reasoning, rather than strictly adhering to the sequence of proficiencies hypothesized by the EPLT. Further, the student’s engagement with cognitive elements which characterize mental activity reveals ways instruction might be tailored to support a student’s relational reasoning. Implications include a more nuanced perspective on individual learning of equipartitioning and important considerations for educators who support relational reasoning in diverse learners.","PeriodicalId":36817,"journal":{"name":"Investigations in Mathematics Learning","volume":"14 1","pages":"288 - 304"},"PeriodicalIF":0.0,"publicationDate":"2022-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45402460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, mathematics teacher educators and researchers have also emphasized the critical role of deep and meaningful mathematical content within curricular efforts that focus on culture and student identity. In this paper, we present how ethnomodeling connects to and extends current literature to apply mathematical modeling to shift toward culturally relevant and sustaining teaching practices while maintaining a focus on deep and meaningful mathematical content. We start by describing the various existing calls, present a synthesis of the literature supporting the components of ethnomodeling, and conclude by proposing a new call to action for the field to deepen existing efforts and plan for actionable steps for using an ethnomodeling approach to impact teacher education programs.","PeriodicalId":36817,"journal":{"name":"Investigations in Mathematics Learning","volume":"14 1","pages":"305 - 319"},"PeriodicalIF":0.0,"publicationDate":"2022-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46636057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In line with this aim, the proof schemes of the freshmen who performed conjecture-proof and theorem-proof tasks were compared. The freshmen were composed of 109 pre-service middle school mathematics teachers who are enrolled in their first year of undergraduate education. The study was modeled as a multiple-case study. Fifty-three freshmen performed conjecture-proof tasks in Case-1, and fifty-six freshmen performed theorem-proof tasks in Case-2. The video recordings, including the written proof reports, reflection papers, and proof explanations of the freshmen, were used as data collection tools in the tasks. The proof schemes were used as construct maps to evaluate the proofs of freshmen and analyzed using Winsteps Rasch software. The proof schemes in freshmen’s proof tasks were evaluated by the Wright Map and supported with direct quotations from the proofs. In the study, it was observed that the proof schemes of freshmen who made proofs based on their own conjectures were mostly empirical and analytical proof schemes, while the proof schemes of freshmen who made proof of the presented theorem were generally external and empirical proof schemes.","PeriodicalId":36817,"journal":{"name":"Investigations in Mathematics Learning","volume":"14 1","pages":"320 - 342"},"PeriodicalIF":0.0,"publicationDate":"2022-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41723859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty-one studies that were published between 1990 and 2019 with problem-posing as the intervention were included in the meta-analysis. A random-effects model was employed with robust variance estimation (RVE) to correct for the intercorrelation between effect sizes when necessary. The estimated average standardized mean difference effect size of problem-posing interventions (g = 0.64) demonstrated that problem-posing had a positive impact on students’ academic outcomes. Specifically, across the interventions, students’ problem-solving skills and mathematical achievement improved by engaging in problem-posing activities. The moderator analyses revealed that problem-posing interventions were more effective when structured, semi-structured, and free problem-posing tasks were all implemented, and longer-duration intervention was associated with larger improvement in students’ mathematical dispositions.","PeriodicalId":36817,"journal":{"name":"Investigations in Mathematics Learning","volume":"14 1","pages":"265 - 287"},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48684833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An innovation that shows promise is to base instructional design upon well-established trajectories of students’ fraction learning.

We report the results of the second of two small studies of an intervention developed using a validated trajectory of students’ fraction concepts. Mixed methods analyses were conducted on students’ problem-solving actions across instructional sessions as well as their performance on a standards-aligned measure of fractional knowledge before and after instruction. Results suggest increases in both conceptual understanding and performance for nine students.

If one considers only interim or final solutions to modeling problems or interviews modelers afterward, often only their explicit models are accessible – those expressed in work products or evinced in verbal and written reflections. The inner world of tacit knowledge and its impacts on mathematical modeling remain largely inaccessible to such approaches. To understand when and how tacit knowledge can emerge onto the explicit plane as insight during modeling, we present an exploratory and instrumental single-case study. We analyze the embodied interactions of a pair of ninth grade (age 14–15) students as they collaboratively solved a modeling problem. We introduce the phenomenon of embodied insight as a pattern of interaction, in which tacit knowledge becomes explicit and shapes modeling work, and we analyze three such episodes from this pair’s modeling. This work contributes to the field by illustrating the potential in studying embodied social discourse in collaboration to reveal the operation of tacit knowledge in mathematical modeling and its expression on the explicit plane.","PeriodicalId":36817,"journal":{"name":"Investigations in Mathematics Learning","volume":"14 1","pages":"215 - 234"},"PeriodicalIF":0.0,"publicationDate":"2022-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44149222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
