In this study, we have explored the effectiveness of two instructional approaches in the context of the motion of objects falling at terminal speed in the presence of air resistance. We ground these instructional approaches in dual-process theories of reasoning, which assert that human cognition relies on two thinking processes. Dual-process theories suggest multiple possible avenues by which instruction might impact student reasoning. In this paper, we compare two possible instructional approaches: one designed to reinforce the normative approach (improving the outputs of the intuitive process) and another that guides students to reflect on and analyze their initial ideas (supporting the analytic process). The results suggest that for students who have already demonstrated a minimum level of requisite knowledge, instruction that supports analysis of their likely intuitive mental model leads to greater learning benefits in the short term than instruction that focuses solely on providing practice with the normative mindware. These results have implications for the design of instructional materials and help to demonstrate how dual-process theories can be leveraged to explain the success of existing research-based materials.
在本研究中,我们探讨了在有空气阻力的情况下,物体以末端速度下落的运动背景下,两种教学方法的有效性。我们将这些教学方法建立在推理的双过程理论基础之上,该理论认为人类的认知依赖于两个思维过程。双过程理论提出了教学可能影响学生推理的多种途径。在本文中,我们比较了两种可能的教学方法:一种旨在强化规范方法(改善直觉过程的输出),另一种则引导学生反思和分析他们的初步想法(支持分析过程)。研究结果表明,对于已经掌握了最低限度的必要知识的学生来说,支持分析他们可能的直觉心智模式的教学在短期内会比只注重提供规范心智软件练习的教学带来更大的学习效益。这些结果对教学材料的设计具有重要意义,并有助于说明如何利用双过程理论来解释现有研究型材料的成功之处。

Despite knowing physics and astronomy doctoral programs are laden with identity-based inequities, they continue to push minoritized students to the margins. This qualitative social network analysis of 100 women and/or lesbian, gay, bisexual, transgender, queer, and more (LGBT+) physics and astronomy Ph.D.’s explores how minoritized physics and astronomy students utilize social networks to navigate departmental exclusion. Our findings indicate that many of the participants’ identities were often unacknowledged or negatively addressed within their graduate education, with only four participants reporting a positive or favorable experience during this period of their career. Direct support from peers, faculty, and identity-based affinity groups was necessary for participants to navigate their educations. This study demonstrated that generic best practices often cannot fully support the diverse range of persons who come to physics and that identity-neutral values in physics further isolate students by insinuating that their own minoritized experiences are not valid.
尽管知道物理学和天文学博士项目充满了基于身份的不平等,但它们仍然将少数群体学生推向边缘。本研究对 100 名女博士和/或女同性恋、男同性恋、双性恋、跨性别者、同性恋者及更多(LGBT+)的物理学和天文学博士进行了社交网络定性分析,探讨了少数群体物理学和天文学学生如何利用社交网络来应对系里的排斥。我们的研究结果表明,许多参与者的身份在他们的研究生教育中经常不被承认或受到负面对待,只有四位参与者报告了他们在这段职业生涯中的积极或有利经历。同行、教师和基于身份的亲和团体的直接支持是参与者在教育过程中游刃有余的必要条件。这项研究表明,一般的最佳实践往往不能完全支持物理学领域的多元化人才,而物理学中的身份中立价值观则暗示学生自己的少数群体化经历是无效的,从而进一步孤立了学生。

Students often struggle in the transition from high school to college. One component of this struggle is adjusting study habits to navigate new academic expectations. Another is establishing new relationships in college that can support their emotional well-being and academic success. We administered surveys consisting primarily of open-ended questions to students taking an introductory physics course in order to gain insight into students’ study habits and support structures and how they change from high school to college. We find that many students learn that they need to dedicate more time outside of class to studying in order to succeed in college. Many students trying to improve their performance report practicing more, but our results suggest that more practice alone is not sufficient; rather, students were able to increase their performance and satisfaction in the course by engaging more deeply with the material. Regarding support structures, we find that in high school, students find their teachers highly supportive and accessible, but they are less likely to approach their college professors for help. Meanwhile, many students find peers to be an important source of support in college as the amount of support they receive from their families diminishes with distance from home. Gaining a better understanding of students’ study habits, support structures, and how they conceptualize them can help us design course structures and messaging that can more effectively help students develop strong learning strategies and social networks.
学生在从高中过渡到大学的过程中经常会遇到困难。这种挣扎的一部分是调整学习习惯,以适应新的学业要求。另一个方面是在大学里建立新的人际关系,以支持他们的情感健康和学业成功。我们对学习物理入门课程的学生进行了调查,主要包括开放式问题,以深入了解学生的学习习惯和支持结构,以及它们如何从高中到大学发生变化。我们发现,许多学生认识到,要想在大学取得成功,他们需要在课外投入更多时间学习。许多试图提高学习成绩的学生都表示要加强练习,但我们的结果表明,仅仅加强练习是不够的;相反,学生们能够通过更深入地学习材料来提高学习成绩和对课程的满意度。在支持结构方面,我们发现,在高中,学生认为他们的老师非常支持他们,而且很容易接近,但他们不太可能向大学教授寻求帮助。同时,许多学生发现,在大学里,同学是重要的支持来源,因为随着离家的距离越来越远,他们从家人那里得到的支持也越来越少。更好地了解学生的学习习惯、支持结构以及他们如何看待这些结构,有助于我们设计课程结构和信息,从而更有效地帮助学生发展强大的学习策略和社交网络。

Student learning in simple electric circuits has been an important area in physics education research. This study builds off a previous investigation that applied the conceptual framework model to examine knowledge integration in student learning of simple electric circuits and developed a multiple-choice concept test for assessing knowledge integration in simple electric circuits. In this study, a conceptual-framework-based teaching intervention was developed and implemented in a controlled study with high school students in China to evaluate the effectiveness of the new instruction. Using the instrument developed in the previous study, a pretest, a post-test, and a delayed post-test were conducted with both groups of students. The delayed post-test was included to further evaluate knowledge retention as evidence of knowledge integration. The results suggest that the conceptual-framework-based teaching intervention was effective in promoting knowledge integration compared to the existing instruction.
学生学习简单电路一直是物理教育研究的一个重要领域。本研究建立在前一项调查的基础上,该调查应用概念框架模型考察了学生学习简单电路的知识整合情况,并开发了用于评估简单电路知识整合情况的多项选择概念测试。本研究开发了基于概念框架的教学干预,并在中国高中生中进行了对照研究,以评估新教学的有效性。使用之前研究中开发的工具,对两组学生进行了前测、后测和延迟后测。延迟后测是为了进一步评估知识保留情况,作为知识整合的证据。结果表明,与现有教学相比,基于概念框架的教学干预能有效促进知识整合。

In this exploratory study, we examined students’ perceptions of inclusion in a calculus-based, introductory physics 1 course for science and engineering majors. This course, offered at a large R1 institution in the United States, was conducted remotely due to the COVID-19 pandemic. Via a survey given at the end of the semester, students rated their course inclusion and provided open-text explanations for their ratings. On average, students rated the course as moderately inclusive. Using inductive qualitative content analysis, six categories emerged: academic, identity, lack of understanding, nonspecific, other, and remote learning. The top three categories were academic (41%), nonspecific (33%), and remote learning (18%). The remote learning category included phrases containing remote learning, Zoom, or COVID-19, along with a second idea explaining the student’s level of inclusion, leading to remote learning subcategories. These subcategories were similar to the other primary categories and the academic subcategories. Many students cited academic reasons for their inclusivity scores, including course structure, teaching practices, instructor-student interaction, student-student interaction, and overall course environment. Importantly, many of these factors are within the instructor’s influence. Chi-square tests indicated that students perceiving high inclusion emphasized academic factors, while those feeling low inclusion focused on the remote learning aspect of the course. Overall, our findings suggest that instructors can significantly influence students’ perceptions of inclusion through various teaching strategies, interactions between instructors and peers, and a welcoming environment. These insights contribute to the ongoing discussion about creating inclusive classrooms by incorporating student perspectives.
在这项探索性研究中,我们考察了学生对理工科专业微积分入门物理 1 课程中的包容性的看法。这门课程在美国一所大型 R1 院校开设,由于 COVID-19 大流行而采用远程授课。通过学期末的调查,学生们对课程的包容性进行了评分,并对他们的评分提供了开放文本解释。平均而言,学生认为课程的包容性适中。通过归纳定性内容分析,得出了六个类别:学术、身份、缺乏了解、非特定、其他和远程学习。排在前三位的类别是学术(41%)、非特定(33%)和远程学习(18%)。远程学习类别包括包含远程学习、Zoom 或 COVID-19 的短语,以及解释学生融入程度的第二个想法,从而形成远程学习子类别。这些子类别与其他主要类别和学术子类别相似。许多学生提到了他们的包容性得分的学术原因,包括课程结构、教学实践、教师与学生的互动、学生与学生的互动以及整体课程环境。重要的是,这些因素中有许多都在教师的影响范围之内。卡方检验表明,认为包容性高的学生强调学术因素,而认为包容性低的学生则关注课程的远程学习方面。总之,我们的研究结果表明,教师可以通过各种教学策略、教师与同学之间的互动以及友好的环境,极大地影响学生的融入感。这些见解有助于人们继续讨论通过纳入学生的观点来创建全纳课堂的问题。

In introductory physics laboratory instruction, students often expect to confirm or demonstrate textbook physics concepts. This expectation is largely undesirable: labs that emphasize confirmation of textbook physics concepts are generally unsuccessful at teaching those concepts and even in contexts that do not emphasize confirmation, such expectations can lead to students disregarding or manipulating their data in order to obtain the expected result. In other words, when students expect their lab activities to confirm a known result, they may relinquish epistemic agency and violate disciplinary practices. We present a contrasting case where, we claim, confirmatory expectations can actually support productive disciplinary engagement. In this case study, we analyze the complex dynamics of students’ epistemological framing in a lab where students’ confirmatory expectations support and even generate epistemic agency and disciplinary practices, including developing original ideas, measures, and apparatuses to apply to the material world.
在物理入门实验教学中,学生往往期望证实或演示教科书上的物理概念。这种期望在很大程度上是不可取的:强调证实教科书物理概念的实验在教授这些概念方面通常是不成功的,即使在不强调证实的情况下,这种期望也会导致学生为了获得预期的结果而忽视或操纵他们的数据。换句话说,当学生期望他们的实验活动能够证实已知结果时,他们可能会放弃认识论的能动性,并违反纪律惯例。我们提出了一个相反的案例,在这个案例中,我们声称确认性期望实际上可以支持富有成效的学科参与。在本案例研究中,我们分析了实验室中学生认识论框架的复杂动态,在实验室中,学生的确认性预期支持甚至产生了认识论能动性和学科实践,包括开发原创性的想法、措施和工具,以应用于物质世界。

Investigating introductory and advanced students’ difficulties with entropy and the second law of thermodynamics using a validated instrument 使用验证工具调查入门级和高级学生在熵和热力学第二定律方面遇到的困难

We use the Survey of Thermodynamic Processes and First and Second Laws-Long (STPFaSL-Long), a research-based survey instrument with 78 items at the level of introductory physics, to investigate introductory and advanced students’ difficulties with entropy and the second law of thermodynamics. We present an analysis of data from 12 different introductory and advanced physics classes at four different higher education public institutions in the United States in which the survey was administered in person to more than 1000 students. We find that a widespread unproductive tendency for introductory students to associate the properties of entropy with those of energy leads to many errors based on an idea of “conservation of entropy,” in which entropy increases are always balanced by equal entropy decreases. For many of the more advanced students (calculus based and upper level), we detect a tendency to expect entropy increases even in processes in which the entropy does not change. We observed a widespread failure to correctly apply the relationship ΔS=Qreversible/T, either by using it for irreversible processes to which it does not apply or by applying it incorrectly or completely neglecting it in reversible processes to which it does apply. We also noted that many introductory students are simply not aware that total entropy must increase in any “spontaneous” heat transfer process. Students at all levels were very frequently found to be confused that while net entropy (system+reservoir) in reversible isothermal processes does not change, the entropy of the working substance itself does indeed increase or decrease depending on whether the process is an expansion or compression. Our findings are broadly consistent with prior research findings in this area, expanding upon them and revealing previously unreported aspects of students’ thinking. Moreover, our results reflect several new problem contexts in addition to those reported in prior research, and our sample population includes large numbers of both introductory and advanced students. Our detailed findings related to common student difficulties with entropy and the second law of thermodynamics before and after traditional instruction in college physics courses can potentially help instructors of these courses improve student understanding of these concepts. These findings can also be valuable for developing effective research-based curricula and pedagogies to reduce student difficulties and help students develop a solid grasp of these fundamental thermodynamic concepts.
我们使用热力学过程及第一和第二定律调查--STPFaSL-Long(STPFaSL-Long)这一基于研究的调查工具,调查了入门级物理水平的 78 个项目,研究了入门级和高级班学生在熵和热力学第二定律方面的困难。我们对来自美国四所公立高等教育机构的 12 门不同的物理入门和进阶课程的数据进行了分析,并亲自对 1000 多名学生进行了问卷调查。我们发现,入门级学生普遍倾向于将熵的特性与能量的特性联系起来,这种非生产性的倾向导致了许多基于 "熵守恒 "思想的错误,在 "熵守恒 "思想中,熵的增加总是由相等的熵的减少来平衡。对于许多高年级学生(以微积分为基础的高年级学生),我们发现他们倾向于认为即使在熵不发生变化的过程中熵也会增加。我们发现,学生普遍不能正确应用 ΔS=Qreversible/T 的关系,要么将其用于不适用的不可逆过程,要么在适用的可逆过程中不正确地应用或完全忽略它。我们还注意到,许多入门级学生根本不知道在任何 "自发 "热传递过程中总熵一定会增加。我们发现,各个年级的学生经常混淆这样一个问题:虽然在可逆等温过程中净熵(系统+贮存器)不会发生变化,但工作物质本身的熵确实会增加或减少,这取决于过程是膨胀还是压缩。我们的研究结果与之前在这一领域的研究结果基本一致,并在此基础上进行了扩展,揭示了学生思维中以前未曾报道过的方面。此外,我们的研究结果还反映了一些新的问题情境,而不是之前研究中报告的那些情境,而且我们的样本人群中既有大量的入门级学生,也有高级学生。在大学物理课程的传统教学前后,我们关于学生在熵和热力学第二定律方面常见困难的详细研究结果,有可能帮助这些课程的教师提高学生对这些概念的理解。这些发现对于开发有效的研究型课程和教学法也很有价值,可以减少学生的困难,帮助学生牢固掌握这些基本的热力学概念。

We present an analysis of data from 12 different introductory and advanced physics classes at four different higher education public institutions in the United States in which the survey was administered in person to more than 1000 students. We find that a widespread unproductive tendency for introductory students to associate the properties of entropy with those of energy leads to many errors based on an idea of “conservation of entropy,” in which entropy increases are <i>always</i> balanced by equal entropy decreases. For many of the more advanced students (calculus based and upper level), we detect a tendency to expect entropy increases even in processes in which the entropy does <i>not</i> change. We observed a widespread failure to correctly apply the relationship <math display=\"inline\" xmlns=\"http://www.w3.org/1998/Math/MathML\"><mrow><mi mathvariant=\"normal\">Δ</mi><mi>S</mi><mo>=</mo><msub><mrow><mi>Q</mi></mrow><mrow><mtext>reversible</mtext></mrow></msub><mo>/</mo><mi>T</mi></mrow></math>, either by using it for <i>irreversible</i> processes to which it does not apply or by applying it incorrectly or completely neglecting it in reversible processes to which it does apply. We also noted that many introductory students are simply not aware that total entropy must increase in any “spontaneous” heat transfer process. Students at all levels were very frequently found to be confused that while net entropy (<math display=\"inline\" xmlns=\"http://www.w3.org/1998/Math/MathML\"><mrow><mi>system</mi><mo>+</mo><mtext>reservoir</mtext></mrow></math>) in reversible isothermal processes does not change, the entropy of the working substance itself does indeed increase or decrease depending on whether the process is an expansion or compression. Our findings are broadly consistent with prior research findings in this area, expanding upon them and revealing previously unreported aspects of students’ thinking. Moreover, our results reflect several new problem contexts in addition to those reported in prior research, and our sample population includes large numbers of both introductory and advanced students. Our detailed findings related to common student difficulties with entropy and the second law of thermodynamics before and after traditional instruction in college physics courses can potentially help instructors of these courses improve student understanding of these concepts.

To address the issue of gender disparity in participation in the physics state matriculation exam, a novel school visit program was designed. The program was facilitated by undergraduate university students of physics and related courses who visited schools providing lower secondary education and delivered a single-session workshop including hands-on demonstrations of physics principles, presentations about famous female scientists, information on physics-related careers, and the importance of adopting a growth mindset. In this paper, we present a detailed description of the principles underlying the workshop’s design and its final outline. Participants’ responses to a pre-post questionnaire are analyzed to assess the immediate effects of the workshop, particularly as regards changes in their opinions about physics and students’ intention to study it for their state matriculation exam. Female and male responses are analyzed separately to establish differences in the intervention’s effect between the two genders. Results show an increase among female students with positive perceptions of their physics knowledge and familiarity with physics role models. Our attempt to boost confidence, enjoyment, and perceptions of the relevance of physics proved challenging but yielded some positive results. Strikingly, girls reported positive change in their ability to imagine themselves as physicists and their intention to study physics for their matriculation exam. The intervention was more successful among younger girls. Results obtained from boys were positive but to a lesser extent. The study demonstrates an encouraging and strong positive impact of a uniquely designed, single-session intervention, especially on adolescent girls, and contributes to research on the effectiveness of gender equality-oriented science outreach interventions.
为了解决参加物理州立预科考试的性别差异问题,我们设计了一项新颖的学校访问计划。该计划由大学物理及相关课程的本科生协助开展,他们走访了提供初中教育的学校,并举办了一次研讨会,内容包括物理原理的动手演示、著名女科学家的介绍、物理相关职业的信息以及采用成长型思维模式的重要性。在本文中,我们将详细介绍工作坊的设计原则和最终大纲。我们分析了参加者对事后调查问卷的答复,以评估研讨会的直接效果,特别是他们对物理的看法的变化以及学生在州预科考试中学习物理的意向。对男女生的回答分别进行了分析,以确定干预效果在两性之间的差异。结果显示,女生对物理知识的积极看法和对物理榜样的熟悉程度都有所提高。事实证明,我们试图增强学生的自信心,提高他们对物理的乐趣和相关性的认识,这种尝试具有挑战性,但也取得了一些积极的成果。令人吃惊的是,女生们报告说,她们在把自己想象成物理学家的能力以及在预科考试中学习物理的意愿方面都发生了积极的变化。干预措施在年龄较小的女生中更为成功。从男生那里获得的结果也是积极的,但程度较低。这项研究表明,一项设计独特的单次干预措施产生了令人鼓舞的积极影响,尤其是对少女产生了积极影响,并有助于研究以性别平等为导向的科学外联干预措施的有效性。

Developing a deeper understanding of scientific concepts is one of the primary goals of science education. To improve students’ conceptual understanding, it is necessary to explore the major characteristics of their learning process. Informed by previous work on conceptual understanding, this study focuses on the concept of evaporation, exploring the level division of students’ conceptual understanding of evaporation and the development of corresponding test questions. The level-based conceptual understanding assessment was tested on 721 seventh-grade Chinese students before and after the evaporation lesson. The results of quantitative and qualitative analyses indicated that the students’ conceptual understanding of evaporation could be divided into three progression levels. Students with a low level of understanding only mechanically remembered the definition of evaporation and could identify evaporation phenomena in their daily lives based on memorized examples. Students with an intermediate level of understanding grasped not only the definition of evaporation but also the factors affecting the evaporation rate. Students with a high level of understanding understood the microscopic nature of evaporation and could explain how these three factors affect the evaporation rate from a microscopic perspective. This study also provides further evidence of the value of grasping the nature of concepts in conceptual understanding.
加深对科学概念的理解是科学教育的主要目标之一。要提高学生的概念理解能力,就必须探索他们学习过程的主要特点。在前人对概念理解研究的启发下,本研究以蒸发概念为研究对象,探索学生对蒸发概念理解的水平划分,并开发相应的测试题。在蒸发课前后,对 721 名七年级中国学生进行了基于水平的概念理解评价测试。定量和定性分析的结果表明,学生对蒸发的概念理解可分为三个进展水平。理解水平较低的学生只是机械地记住了蒸发的定义,并能根据记忆中的例子找出日常生活中的蒸发现象。理解水平中等的学生不仅掌握了蒸发的定义,还了解了影响蒸发率的因素。理解水平高的学生理解了蒸发的微观本质,并能从微观角度解释这三个因素是如何影响蒸发速率的。这项研究还进一步证明了把握概念的本质在概念理解中的价值。
