Teachers often struggle to implement inquiry‐based science teaching. To support them, IndagApp—a 3D educational app that offers curriculum‐aligned, inquiry‐based lesson plans—was designed. The app is rooted in the inquiry phases recommended in best‐practices literature, which arguably align with most international standards. This study describes IndagApp and evaluates its usability with fifth‐graders from two elementary schools in Spain (N = 43). The system usability scale (SUS) and the Pictorial‐SUS were used to collect students' feedback on usability. Both frequentist and Bayesian analyses were conducted to compare the mean SUS score with established benchmarks for usability. The results showed that IndagApp had high usability ratings, with most students rating it as the “Best imaginable” or “Good.” The mean SUS score was 84.816, which was significantly higher than the benchmark score of 68. There were no differences in usability between girls and boys, and students in private and public schools. These findings suggest that IndagApp is a valuable resource for inquiry learning in elementary grades and has significant implications for science education and science teacher professional development, as it helps teachers adopt reform‐oriented teaching practices that align with the curricular standards and goals.
教师在实施探究式科学教学时往往会遇到困难。为了给他们提供支持,我们设计了 IndagApp--一款 3D 教育应用程序,提供与课程一致的探究式课程计划。该应用程序以最佳实践文献中推荐的探究阶段为基础,可以说与大多数国际标准相一致。本研究介绍了 IndagApp,并对其可用性进行了评估,评估对象是来自西班牙两所小学的五年级学生(43 人)。系统可用性量表(SUS)和Pictorial-SUS用于收集学生对可用性的反馈意见。通过频数分析和贝叶斯分析,将 SUS 的平均得分与可用性的既定基准进行了比较。结果显示,IndagApp 的可用性评分很高,大多数学生将其评为 "可想象的最佳 "或 "良好"。平均 SUS 得分为 84.816,明显高于 68 分的基准分数。男女生、私立学校和公立学校的学生在可用性方面没有差异。这些研究结果表明,IndagApp 是小学各年级探究学习的宝贵资源,对科学教育和科学教师的专业发展具有重要意义,因为它有助于教师采用与课程标准和目标相一致的、以改革为导向的教学实践。

Providing teachers opportunities to lead has a positive effect on student achievement and teacher retention, which is critical in a time when there is a shortage of qualified STEM teachers. While there is research on the impact of professional development (PD) programs on teacher leadership, there is sparse literature on the impact of award or recognition programs such as the Presidential Awards for Excellence in Mathematics and Science Teaching (PAEMST). In this qualitative case study of eight PAEMST teacher leaders, we found that the PAEMST program accelerates and promotes STEM teacher leadership trajectories. The PAEMST program does this through: (a) the application process, which provided teachers with an informal PD experience; (b) the award notification experience, which served as external validation to boost teachers' confidence and identification as leaders; and (c) external validation and an expanded professional network, all of which led to increased leadership opportunities at the state and national level. Furthermore, we found increased opportunities to lead within the school and district was mediated by the reaction of their colleagues, school culture, and school leadership structures. We offer recommendations for administrators and practitioners in providing teacher leadership trajectories for awardees to positively influence their schools.
为教师提供领导机会对学生的成绩和教师的留任有着积极的影响,这在合格的 STEM 教师短缺的时代是至关重要的。虽然有关于专业发展(PD)项目对教师领导力影响的研究,但关于诸如 "总统数学与科学教学卓越奖"(PAEMST)等奖励或表彰项目影响的文献却很少。在这项对八位 PAEMST 教师领导者的定性案例研究中,我们发现 PAEMST 计划加速并促进了 STEM 教师领导力的发展。PAEMST 项目通过以下途径实现了这一目标:(a)申请过程,为教师提供了非正式的专业发展经历;(b)获奖通知经历,作为外部验证,增强了教师作为领导者的信心和认同感;以及(c)外部验证和扩大的专业网络,所有这些都增加了教师在州和国家层面的领导机会。此外,我们还发现,在学校和地区内领导机会的增加受到同事反应、学校文化和学校领导结构的影响。我们为管理者和实践者提供建议,为获奖者提供教师领导轨迹,以积极影响他们的学校。

As the world becomes increasingly rooted in all forms of inequities, so does the need to fight its causatives. This study is concerned with ensuring that science education serves to reinforce gender equity against traditional narratives. We explored the potency of culturo‐techno‐contextual approach (CTCA) in leveling the playing field while promoting meaningful learning of chemistry among male and female students. Two separate quasi‐experimental studies were conducted on two perceived difficult topics in chemistry—nuclear chemistry and electrochemistry using senior secondary school two (equivalent of grade 11 in the United States system) students (NStudy 1 = 221, NStudy 2 = 141). In each study, the experimental groups were taught using CTCA, while the control groups were taught with lecture method. The research design was explanatory and sequential with a quasi‐experimental framework. The nuclear chemistry achievement test and the electrochemistry achievement test that were used to collect data had a reliability coefficient of 0.83 and 0.76, respectively. Analysis of covariance was used to analyze the quantitative data, while the qualitative data used a thematic approach. The studies found no significant difference in the achievement (post‐posttest) of the male and female students. Within the study limits, we concluded that CTCA is a viable tool for bridging the gender difference in chemistry learning.
随着世界日益根深蒂固地存在各种形式的不平等,我们也有必要消除不平等的根源。本研究关注的是确保科学教育有助于加强性别平等,反对传统叙事。我们探讨了文化-技术-情境教学法(CTCA)在促进男女学生有意义地学习化学的同时,在公平竞争中的作用。我们以高中二年级(相当于美国的 11 年级)的学生(研究 1 = 221 人,研究 2 = 141 人)为对象,对化学中的两个难点--核化学和电化学--进行了两项独立的准实验研究。在每项研究中,实验组采用 CTCA 教学法,对照组采用讲授法。研究设计采用解释性和顺序性的准实验框架。用于收集数据的核化学成绩测验和电化学成绩测验的信度系数分别为 0.83 和 0.76。定量数据采用协方差分析法,定性数据则采用专题分析法。研究发现,男女学生的成绩(后测)没有明显差异。在研究范围内,我们认为 CTCA 是弥合化学学习中性别差异的可行工具。

Mathematical writing (MW) is an important yet underutilized form of mathematics discourse. Given the lack of attention to MW, there are few resources to support the implementation and assessment of MW. This study responds to the lack of resources by describing a MW unit focused on fractions that was implemented during a summer school program to support rising fourth grade students with explanatory and argumentative writing. Findings from the study revealed that students used different forms of reasoning about fractions to compose their mathematical argument and explanation. We also identified five categories that captured how students communicated a mathematical argument and explanation: writing organization, precise mathematical vocabulary, mathematics content, mathematical representation, and characteristics specific to a mathematical argument/explanation. The five categories led to the development of an analytic rubric for argumentative and explanatory writing.
数学写作(MW)是数学话语的一种重要形式,但却未得到充分利用。由于缺乏对数学写作的关注,支持数学写作实施和评估的资源也很少。本研究针对资源匮乏的问题,介绍了一个以分数为重点的数学写作单元,该单元是在暑期学校项目中实施的,旨在帮助四年级学生进行解释性和论证性写作。研究结果表明,学生在撰写数学论证和解释时使用了不同形式的分数推理。我们还确定了学生如何表达数学论证和解释的五个类别:写作组织、精确的数学词汇、数学内容、数学表达以及数学论证/解释的具体特征。根据这五个类别,我们制定了论证和解释性写作的分析评分标准。

This 2‐year qualitative case study focuses on one emergent mathematics teacher leader, Mr. Miller, and his conceptualization of Social Justice Mathematics (SJM). SJM is a justice‐oriented pedagogical approach where students simultaneously learn dominant mathematics and explore social injustices to take action toward justice. Using Rodriguez's (Journal of Research in Science Teaching, 1998, 35, 589–622) sociotransformative constructivism framework, findings illuminate how dialogic conversation, authentic activity, and metacognition supported Mr. Miller's reflexivity about his positionality, which he described as “upper middle class, highly educated parents, white, male,” in relationship to his students' positionality. He taught in a public charter high school in an urban city in the Northeast United States, where approximately 60% of students identified as Black, 30% white, 10% mixed race, 1% Asian American, 1% Latine, and less than 1% Indigenous, with 60% of students qualifying for free or reduced lunch. The article discusses of the importance of reflexivity for teachers and teacher leaders of all backgrounds, and especially when educators of dominant backgrounds work with students of historically marginalized backgrounds. The article calls for further research with more experienced mathematics teacher leaders of various backgrounds and contexts to further investigate justice‐centered mathematics teacher leadership.
这项为期两年的定性案例研究主要关注一位新锐数学教师领导者--米勒先生,以及他对社会正义数学(SJM)的构想。社会正义数学是一种以正义为导向的教学方法,学生在学习主流数学的同时,还能探索社会不公正现象,从而为实现正义而采取行动。利用罗德里格斯(Journal of Research in Science Teaching, 1998, 35, 589-622)的社会转型建构主义框架,研究结果阐明了对话性对话、真实活动和元认知如何支持米勒先生对自己的立场(他将自己的立场描述为 "中上层阶级、受过高等教育的父母、白人、男性")与学生的立场之间的关系进行反思。他在美国东北部一个城市的公立特许高中任教,该校约 60% 的学生被认定为黑人,30% 为白人,10% 为混血儿,1% 为亚裔美国人,1% 为拉丁裔,不到 1% 为土著人,60% 的学生有资格享受免费或减价午餐。文章讨论了反思对各种背景的教师和教师领导的重要性,尤其是当主流背景的教育工作者与历史上被边缘化的学生合作时。文章呼吁对各种背景和环境下更有经验的数学教师领导进行进一步研究,以进一步探讨以正义为中心的数学教师领导力。

Solving word problems is challenging for many children, but particularly for those with language difficulties. The objective was to examine the nature of the challenges experienced by children with language difficulties as they solved word problems in the context of a developmental‐trajectory instructional sequence. We recruited 45 third graders with (n = 17) and without (n = 28) language difficulties from public and private schools and one speech‐language therapy clinic. They solved word problems with additive change and compare structures and language that was either consistent or inconsistent with the structure. The instruction was based on successive simplifications to the problems whenever the child was unable to apply a structurally appropriate strategy: removing irrelevant literal information from the problem, simplifying the text syntactically, and removing irrelevant numerical information. The performance of children with language difficulties was lower than that of the typically developing children and the simplifications did not support performance to the same extent. The presence of irrelevant numerical information was challenging, especially for children with language difficulties. Removing irrelevant information from the problem was followed by stronger performance on change problems and those with consistent language, revealing that the instructional supports were not sufficient for compare and inconsistent problems.
解决文字问题对许多儿童来说都具有挑战性,对有语言障碍的儿童来说更是如此。我们的目的是研究有语言障碍的儿童在按照发展轨迹教学顺序解决文字问题时所遇到的挑战的性质。我们从公立和私立学校以及一家言语治疗诊所招募了 45 名三年级学生,其中有语言障碍的(17 人)和没有语言障碍的(28 人)各占一半。他们解决了带有加法变化的单词问题,并比较了结构和与结构一致或不一致的语言。每当儿童无法应用结构适当的策略时,就会对问题进行连续简化,包括删除问题中无关的文字信息、简化文本的句法和删除无关的数字信息。有语言障碍的儿童的成绩低于发育正常的儿童,而且简化对他们的成绩也没有同样大的帮助。无关数字信息的存在具有挑战性,对有语言障碍的儿童来说尤其如此。去除问题中的无关信息后,儿童在变化问题和语言一致问题上的表现更佳,这表明教学支持对比较问题和语言不一致问题的支持是不够的。

Increasing demand for high‐quality STEM education calls for the formation and retention of effective educators with STEM expertise; yet endeavors to meet this demand require organizational structures and supports that can overcome the lack of collective understanding around STEM education, limited STEM knowledge by leadership, and mounting teacher attrition. STEM teacher leadership is one mechanism for addressing this challenge by empowering excellent classroom teachers with opportunities to institutionally shape STEM learning, without extracting them from their instructional role. This paper offers a STEM teacher leadership framework that targets teachers' identity development toward an equity‐focused, transformational STEM teacher leader. First, we examine the field of teacher leadership (both STEM‐specific and generally) to provide a foundation for the areas of potential impact by STEM teacher leaders, as well as dispositions and stances that support their emergent leadership.

对高质量 STEM 教育日益增长的需求,要求培养和留住具有 STEM 专业知识的有效教育工作者;然而,要满足这一需求,需要组织结构和支持,以克服对 STEM 教育缺乏集体理解、领导层对 STEM 知识有限以及教师自然减员不断增加等问题。STEM 教师领导力是应对这一挑战的一种机制,它赋予优秀的任课教师从制度上塑造 STEM 学习的机会,同时又不会使他们脱离教学角色。本文提供了一个 STEM 教师领导力框架,该框架针对教师的身份发展,使其成为一个注重公平的、变革性的 STEM 教师领导者。首先,我们研究了教师领导力的领域(包括 STEM 领域和一般领域),为 STEM 领域教师领导力的潜在影响领域以及支持其新兴领导力的态度和立场奠定了基础。作为对文献的补充,我们从一项针对 STEM 学科中年级教师的多年期专业发展项目的基线调查和访谈中,探索并提升了有抱负的 STEM 教师领导者的视角。我们根据这些资料反复推敲出了一个框架,其中包括我们对 STEM 教育公平性的立场、八种处置方式以及在 K-8 学校环境中塑造 STEM 教师领导力的四个知识和实践领域。

Providing opportunities for students to talk directly with their peers is a critical dimension to facilitating discussions in mathematics and science, including argumentation‐focused discussions in which students construct arguments and critique others' arguments. Research suggests that supporting student‐to‐student talk and facilitating argumentation discussions are complex and challenging practices for preservice teachers (PSTs). Elementary PSTs from two mathematics and two science methods courses practiced facilitating student‐to‐student talk within the context of an argumentation‐focused discussion. This study's main purpose was to explore the prompts that 29 PSTs used to encourage student‐to‐student talk in a simulated classroom. Findings show the PSTs were able to use direct prompts that encourage student‐to‐student talk but were just as likely to use prompts that may discourage students from talking to each other. Most direct prompts PSTs used to encourage student‐to‐student talk were for the purpose of argumentation construction and/or critique. PSTs were more likely to use indirect prompts, much like Talk Moves, that encourage students to consider others' ideas rather than requesting that students talk with each other. These findings have important implications for future research, as well as for teacher educators and professional learning facilitators who support teachers learning to encourage student‐to‐student talk during argumentation‐focused discussions.
为学生提供与同伴直接交流的机会,是促进数学和科学讨论的一个重要方面,其中 包括以论证为重点的讨论,学生在讨论中构建论点并批判他人的论点。研究表明,对于职前教师(PSTs)来说,支持学生与学生之间的谈话和促进论证讨论是复杂而具有挑战性的实践活动。来自两门数学课程和两门科学方法课程的小学职前教师在以论证为重点的讨论中练习了如何促进学生之间的交流。本研究的主要目的是探究 29 名小学生教师在模拟课堂上鼓励学生与学生交谈时所使用的提示语。研究结果表明,PST 能够使用鼓励学生之间交谈的直接提示语,但也有可能使用可能会阻止学生之间交谈的提示语。PST 用于鼓励学生之间交谈的大多数直接提示都是为了建构论点和/或进行批评。PST 更倾向于使用间接提示,就像 Talk Moves 一样,鼓励学生考虑他人的想法,而不是要求学生相互交谈。这些发现对今后的研究以及教师教育者和专业学习促进者都有重要意义,他们可以帮助教师学会在以论证为重点的讨论中鼓励学生之间的交谈。
