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.","PeriodicalId":93272,"journal":{"name":"Chemistry Teacher International : best practices in chemistry education","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136264249","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}

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.","PeriodicalId":93272,"journal":{"name":"Chemistry Teacher International : best practices in chemistry education","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135353910","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}

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.","PeriodicalId":93272,"journal":{"name":"Chemistry Teacher International : best practices in chemistry education","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44208691","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}

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.

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.","PeriodicalId":93272,"journal":{"name":"Chemistry Teacher International : best practices in chemistry education","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44991297","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}

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. Our preliminary studies, performed in Chemistry laboratories, indicated that this methodology enabled an efficient formative assessment of the learning process during the course. This tool might help students to rapidly improve their performance in laboratory courses, by stimulation of a continuous reflection process.","PeriodicalId":93272,"journal":{"name":"Chemistry Teacher International : best practices in chemistry education","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44325584","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}

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.","PeriodicalId":93272,"journal":{"name":"Chemistry Teacher International : best practices in chemistry education","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47367604","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}
