Abstract During the COVID-19 pandemic, the unexpected lockdown of schools brought many challenges to redesigning the teaching and learning of chemistry at the secondary schooling level. The demand for online teaching under COVID-19 conditions was, however, also an opportunity to reflect on introducing new content, pedagogies, and media. This paper reflects on the implementation of a chemistry lesson plan focusing on the socio-scientific issue of ethanol used for hand sanitizers in Italy. Ethanol is possibly the most common ingredient of hand sanitizer lotions and provides an authentic context for the learning of and about chemistry. The objective was to promote students’ awareness of the deep interconnections between science, society, ethics, and the environment through a socio-scientific issues-based approach.
新冠肺炎大流行期间,意外的学校封锁给中学化学教学的重新设计带来了诸多挑战。然而,在新冠疫情背景下,对在线教学的需求也是一个反思引入新内容、新教学法和新媒体的机会。本文反映了一个化学课程计划的实施重点是社会科学问题的乙醇用于洗手液在意大利。乙醇可能是洗手液中最常见的成分,它为化学的学习提供了一个真实的背景。目的是通过基于社会科学问题的方法,提高学生对科学、社会、伦理和环境之间深刻联系的认识。

Abstract Electrochemistry is an essential context for understanding current energetic technological processes, especially those that use batteries. On the other hand, it is one of the most neglected subjects in the classroom for reasons of associated complexity. Because of this, we have sought new methodological strategies to overcome the difficulties encountered in teaching practice. Thus, this research aims to investigate the possible contributions of a didactic sequence on the disposal of batteries from the teaching by research for the learning of electrochemistry. A qualitative methodology, a case study, applied in a high school class was adopted. The sequence consisted of six methodological steps: implementation of the problem situation; developed hypotheses; a class on electrochemistry; investigative experiment on the decomposition of batteries in aqueous solutions; systematization and communication of results. The results showed that before the application of the didactic sequence, most of the students did not know the dangers that improper disposal of batteries causes to the environment and did not understand how galvanic cells generate electrical energy from a redox reaction. After the sequence was developed, most students were able to identify and conceptualize the main electrochemical terms studied from a critical thought about this problem.
电化学是理解当前能源技术过程的重要背景,特别是那些使用电池的技术过程。另一方面,由于相关的复杂性,它是课堂上最被忽视的科目之一。正因为如此,我们一直在寻求新的方法策略来克服教学实践中遇到的困难。因此,本研究旨在探讨以研究为教的电池处理教学顺序对电化学学习的可能贡献。本研究采用定性研究方法,以个案研究的方式,应用于一个高中班级。该序列包括六个方法学步骤:问题情境的实施;假设开发的;电化学课;电池在水溶液中分解的研究实验结果的系统化和沟通。结果显示,在应用讲授顺序之前,大部分学生并不知道不当处置电池对环境造成的危害,也不了解原电池如何通过氧化还原反应产生电能。在序列形成后,大多数学生能够通过对这个问题的批判性思考来识别和概念化所研究的主要电化学术语。

Abstract This paper presents the German translation and replication of the Students’ Understanding of Models in Science (SUMS) instrument, aiming to assess how first-semester university students comprehend the submicroscopic level in chemistry courses. The assessment of students’ understanding is a prerequisite for improving teaching practices, particularly in addressing the persistently high drop-out rates observed in chemistry and chemistry-related programs. Employing a quantitative methodology, a sample of 181 undergraduate chemistry students was surveyed. The data were analyzed using structural equation modeling, resulting in two statistical models that demonstrated an excellent fit to the data, although no empirical preference could be established for one model over the other. Based on the investigation, framing models as exact replicas of the natural world cannot be considered an empirically meaningful dimension of understanding models in science. Additionally, the reliabilities of the latent constructs were found to be insufficiently low to establish generalizable measurements. These findings are discussed with a focus on epistemology and advocate for a stronger integration of model theory in chemistry teaching and learning. Finally, the importance of establishing a stronger connection between empirical evidence and the implementation of curricular changes in higher education is emphasized.
摘要:本文介绍了“学生对科学模型的理解”(sum)仪器的德文翻译和复制,旨在评估大学一学期学生对化学课程亚微观层面的理解情况。评估学生的理解能力是改善教学实践的先决条件,特别是在解决化学和化学相关课程中观察到的持续高辍学率方面。采用定量方法,对181名本科化学专业学生进行了抽样调查。使用结构方程模型对数据进行了分析,得出了两个统计模型,这些模型与数据非常吻合,尽管无法建立一个模型优于另一个模型的经验偏好。基于调查,框架模型作为自然世界的精确复制品不能被认为是理解科学模型的经验意义维度。此外,发现潜在构念的信度不够低,无法建立可推广的测量。这些发现在认识论的重点上进行了讨论,并提倡在化学教学和学习中加强模型理论的整合。最后,强调了在经验证据与高等教育课程改革实施之间建立更强联系的重要性。

Abstract Emergency Remote Teaching (ERT) was implemented during COVID-19 crisis lockdowns. New challenges arose and teachers sought support. Professional Learning Communities (PLCs), where teachers from similar backgrounds meet for learning and discussions, provided one channel of support. The study aimed to better understand PLCs’ role in challenging times. Therefore, we asked: 1. What challenges did teachers face, in addition to pedagogical ones, during ERT? 2. How did the various members of the PLC perceive support as shown by their descriptions of PLC activities? 3. In what ways did the ERT experience shape the teachers’ perceptions of mutual assistance? The research setting was a PLC network for chemistry teachers that met since 2018 face-to-face or via Zoom. PLCs were found important in facing both professional and emotional challenges. Discussions, sharing of teaching materials, and real-time support addressed professional challenges. Having colleagues who faced similar challenges provided support and eased communication. Thus, PLC membership helped teachers face daily challenges and improved their well-being. PLCs are therefore recommended for routine and future hardships. In practice, PLC leaders can use the results to improve teacher relationships. Conclusions add to understanding teacher collaboration in PLCs formed in diverse contexts.
摘要紧急远程教学(ERT)是在新冠肺炎危机封锁期间实施的。出现了新的挑战,教师们寻求支持。专业学习社区(PLC)提供了一个支持渠道,来自类似背景的教师在这里聚会学习和讨论。这项研究旨在更好地了解PLC在充满挑战的时代中的作用。因此,我们问:1。在ERT期间,除了教学方面的挑战外,教师还面临哪些挑战?2.PLC的各个成员如何看待他们对PLC活动的描述所显示的支持?3.ERT经历在哪些方面塑造了教师的互助观念?研究环境是一个可编程逻辑控制器网络,自2018年以来,化学教师面对面或通过Zoom会面。PLC被发现在面对职业和情感挑战时都很重要。讨论、教材共享和实时支持解决了专业挑战。有面临类似挑战的同事提供了支持并简化了沟通。因此,PLC会员帮助教师面对日常挑战,改善他们的幸福感。因此,建议PLC用于日常和未来的困难。在实践中,PLC领导可以利用结果来改善教师关系。结论有助于理解在不同背景下形成的PLC中的教师合作。

Abstract Offering virtual laboratories to chemical engineering students is likely to extend beyond the COVID-19 era. Thus, there is a need to develop more simulation-based tasks in a wide blend of subjects, spanning thermodynamics, chemical reactions, and unit operations. Molecular and material modeling based on density functional theory (DFT) calculations provides limitless opportunities to train students on how to obtain thermokinetic values that are typically measured experimentally. Through a series of illustrative cases, this contribution provides detailed procedures pertinent to calculating reaction rate constants, standard enthalpies of reactions, redox potentials, equilibrium reaction constants, and surface-assisted mechanisms. We hope that DFT-operated virtual labs will assist students in attaining learning outcomes and promote their self-learning in the above-mentioned subjects. From a broader prospective, the presented case studies are expected to encourage students to appreciate the practical applications of DFT, not only in the academic but also in the industrial domains.
为化学工程专业的学生提供虚拟实验室可能会超越COVID-19时代。因此,有必要在广泛的学科中开发更多基于模拟的任务,包括热力学、化学反应和单元操作。基于密度泛函理论(DFT)计算的分子和材料建模为训练学生如何获得通常通过实验测量的热动力值提供了无限的机会。通过一系列说明性的案例,本书提供了计算反应速率常数、标准反应焓、氧化还原电位、平衡反应常数和表面辅助机理的详细程序。我们希望dft运作的虚拟实验室能协助学生取得学习成果,并促进他们在上述科目上的自学。从更广泛的角度来看,所提出的案例研究希望鼓励学生欣赏DFT的实际应用,不仅在学术领域,而且在工业领域。

Abstract Conservation Science Education Online (CSEO) is a new online resource that shares strategies for teaching science in art conservation and related cultural heritage fields. An overview will be given of how undergraduate chemistry curricula in the United States have used examples from cultural heritage. The field of art conservation will then be described with an emphasis on the science curricula taught in art conservation programs around the world. Challenges include relating theoretical learning to real-world applications and teaching scientific terminology and concepts to students who may have limited science backgrounds; as well, there is a lack of textbooks and resources with appropriate case studies. The newly launched CSEO online resource offers freely available, effective teaching methods in the form of modules developed by international educators in the field. The inaugural CSEO Conference 2022 served as an introduction to the online resource for a global audience and was the first dedicated conference to bring together heritage science educators to discuss challenges and teaching strategies with the goal of building such a resource. The conference facilitated discussions among participants about teaching strategies, with the intention that these topics would become modules for the online resource, available to all science educators.

Abstract Learners’ independence and self-regulated learning (SRL) may be achieved by online teaching, promoting learners’ 21st century skills. Transitioning into online learning and teaching requires a variety of teachers’ knowledge types and competencies. Mapping these knowledge types with a dedicated tool can help improve teachers’ professional development processes to enhance the SRL of teachers and subsequently students. We aimed at investigating the types of knowledge chemistry teachers expressed in online assignments they had designed, which included guidelines to foster their students’ SRL, and reviewing their reflections upon implementing these assignments. The participants were 20 high school chemistry teachers, who took part in two professional development programs focusing on fostering students’ SRL skills in online assignments, the teachers had designed. Research tools included teachers’ online assignments and teachers’ written reflections. We analyzed the assignments using a special rubric, which consists of three types of teachers’ knowledge: technological pedagogical and content knowledge (TPACK), assessment knowledge (AK), and SRL. Findings show that the analysis rubric of online assignments, designed by teachers, enabled identifying various teacher knowledge types and their levels. The use of a validated rubric for mapping and assessing teachers’ knowledge types is a methodical contribution to research on chemistry teachers’ professional development.
在线教学可以实现学习者的自主学习和自我调节学习,提高学习者的21世纪技能。向在线学习和教学过渡需要教师具备多种知识类型和能力。使用专用工具绘制这些知识类型有助于改善教师的专业发展过程,从而提高教师和学生的SRL。我们的目的是调查化学教师在他们设计的在线作业中表达的知识类型,其中包括培养学生SRL的指导方针,并回顾他们在实施这些作业时的反思。参与者是20名高中化学教师,他们参加了两个专业发展项目,重点是在教师设计的在线作业中培养学生的SRL技能。研究工具包括教师的在线作业和教师的书面反思。我们使用一个特殊的标题来分析作业,该标题由三种类型的教师知识组成:技术、教学和内容知识(TPACK)、评估知识(AK)和SRL。研究结果表明,由教师设计的在线作业分析标题能够识别教师的各种知识类型及其水平。使用一个经过验证的标准来绘制和评估教师的知识类型,是对化学教师专业发展研究的一个系统贡献。

An interactive platform for formative assessment and immediate feedback in laboratory courses 在实验室课程中进行形成性评估和即时反馈的互动平台
Q2 EDUCATION, SCIENTIFIC DISCIPLINES Pub Date : 2023-08-23 DOI: 10.1515/cti-2022-0049

Abstract The aim of this work is to use the laboratory platform as a unique tool for engaging and encouraging the students to develop critical thinking and guided self-evaluation abilities. Moreover, the fact that the teaching process in the lab is held in small groups enables the detection of difficulties in an early stage, thus allowing an immediate feedback and relevant assistance. Taking advantage of this unique environment we have developed a rubric score based interface for students and teaching assistants (TAs) aimed to encourage student’s reflection and engagement while enabling a rational and valid grading of students’ performance by the TAs. The rubric consists of eight parameters which are evaluated in each lab session, both by the student and the TA. Following the lab session, a comparison of both evaluations is performed by the lab manager thus enabling real time intervention and formative assessment, along with important insights on the learning process of the student.

摘要这项工作的目的是将实验室平台作为一种独特的工具,吸引和鼓励学生发展批判性思维和引导自我评价能力。此外,实验室的教学过程是以小组形式进行的,这使得能够在早期发现困难,从而获得即时反馈和相关帮助。利用这种独特的环境,我们为学生和助教开发了一个基于评分标准的界面,旨在鼓励学生的反思和参与,同时使助教能够对学生的表现进行合理有效的评分。该准则由八个参数组成,这些参数由学生和助教在每次实验中进行评估。在实验室会议之后,实验室经理对两种评估进行比较,从而实现实时干预和形成性评估,以及对学生学习过程的重要见解。我们在化学实验室进行的初步研究表明,这种方法能够对课程中的学习过程进行有效的形成性评估。这个工具可以通过刺激持续的反思过程,帮助学生快速提高他们在实验室课程中的表现。

Abstract Digitalization leads to an increased importance of digital educational content for learning in higher education as well as in the sciences. The investigation of individual factors (e.g., motivation, self-efficacy, attitudes) influencing the intention to use digital educational content is a major research interest in design and implementation of suitable content (Hsu, J.-Y., Chen, C.-C., & Ting, P.-F. (2018). Understanding MOOC continuance: An empirical examination of social support theory. Interactive Learning Environments, 26(8), 1100–1118), yet to date without differentiation by discipline. A questionnaire following the Theory of Planned Behavior (Fishbein, M., & Ajzen, I. (2010). Predicting and changing behavior: The reasoned action approach. Psychology Press. http://site.ebrary.com/lib/alltitles/docDetail.action?docID=10462474) was developed to analyze relationships between STEM students’ individual beliefs and their personal motivation to use digital educational content. In November 2021, a total of 662 STEM students from 8 universities in Germany participated in the study. Analyses showed differences within the group of STEM students: science students rated their digital skills lower and expected more difficulties compared to other STEM students, but did not differ in terms of their motivation. For science students, unlike other STEM students, motivation was predicted only by attitudes and digital skills. Moreover, the present results suggest that, first, the focus of the design should be on learning environment rather than on digital tools, and second, the potential of collaboration is largely unrecognized by students.
摘要数字化使数字教育内容在高等教育和科学领域的学习中变得越来越重要。对影响使用数字教育内容意图的个人因素(如动机、自我效能感、态度)的调查是设计和实施合适内容的主要研究兴趣(Hsu,J.-Y,Chen,C.-C,&Ting,P.-F.(2018)。理解MOOC持续性:社会支持理论的实证检验。交互式学习环境,26(8),1100–1118),迄今为止尚未按学科进行区分。遵循计划行为理论的问卷调查(Fishbein,M.,&Ajzen,I.(2010)。预测和改变行为:理性行动方法。心理学出版社。http://site.ebrary.com/lib/alltitles/docDetail.action?docID=10462474)旨在分析STEM学生的个人信仰和他们使用数字教育内容的个人动机之间的关系。2021年11月,共有来自德国8所大学的662名STEM学生参与了这项研究。分析显示,STEM学生群体内部存在差异:与其他STEM学生相比,理科学生的数字技能评分较低,预计会遇到更多困难,但在动机方面没有差异。对于理科学生来说,与其他STEM学生不同,动机只能通过态度和数字技能来预测。此外,目前的研究结果表明,首先,设计的重点应该放在学习环境上,而不是数字工具上;其次,学生们在很大程度上没有认识到合作的潜力。
