Piaget’s cognitive development theory and Johnstone’s cognitive load theory served as the theoretical foundations. A large, public school district in the state of Utah provided the de-identified, archival data for this study, which consisted of students that took a chemistry course and chemistry EOC exam in 2015-2016 or 2016-2017. The research question sought to find whether there was a statistically significant difference in chemistry EOC exam scores for high school students in both groups. A one-way ANOVA demonstrated a statistically significant difference between the POGIL and non-POGIL student groups on the dependent variable of chemistry EOC exam scores, F(1, 314) = 29.91, p < .001, partial η2 = .087, (p < .05). This study supported POGIL pedagogy as an effective instructional strategy for improving student chemistry EOC exam scores.","PeriodicalId":156311,"journal":{"name":"Science Education International","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128400485","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 aim was to investigate how chemistry discussions mediated by representations, contribute to second language students’ development in the language of chemistry. The study took place in three multilingual upper secondary classes. Participating students were (n=16) second language learners and (n=14) first language learners. There were in total eight different first languages represented. Data comprised of polymeric concept descriptions, audio recordings, and photos taken during modelling. The concept descriptions were analysed by an inductive content analysis which was then used for a deductive analysis of the modelling-activity. The results show that 65% of second language learners’ concept descriptions showed an increased clarity, and 45% showed increased use of chemical concepts after the modelling-activity. This study highlights how students in a multilingual context develop their language of chemistry by discussing chemistry scaffolded by representations. The results show that second language learners in a multilingual context benefited from the modelling-activity. As such, the study acknowledges that modelling contexts can be used in teacher education, both in-service and pre-service, to highlight the importance of the role of representations when teaching in the multilingual context.","PeriodicalId":156311,"journal":{"name":"Science Education International","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123427243","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}

On the other hand, in the qualitative results, it was reported that the problem-based STEM education created a positive effect as cognitive maturity and innovativeness in the students' feelings, thought and behaviours. It was concluded that the students used the inter-disciplinary knowledge with the problem-based STEM activities; found the problem solving, understanding the problem and working with their friends favourably.

The analytical chemistry laboratory (ACL) course was reorganized by replacing the traditional laboratory approach with the FL approach that established the context with the environment. The data were obtained through a conceptual understanding test (CUT) which was developed by the researchers, which consisted of five open-ended questions. The CUT was used as a pre-test and post-test along with an interview form. Results showed that the reorganization of the traditional laboratory course in accordance with the nature of action research and its integration with the flipped learning approach had a positive effect on the prospective teachers’ learning and opinions about the course. Also, it was determined that PSTs’ interpretation ability related to environmental problems in the chemical dimension improved significantly. However, despite this increase, it was concluded that they could not reach a sufficient level in terms of producing solutions to environmental problems. Considering that the effectiveness of FL practices both teaching subjects and environmental problems in ACL course, it is thought to be beneficial to use this approach in another laboratory course.","PeriodicalId":156311,"journal":{"name":"Science Education International","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121640422","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 data from the questionnaire were analysed using descriptive statistics. The findings revealed that the use of web-based technology instructional approach during lessons delivery and accessing the internet to search for information during instructional hours provided opportunities for students to access internet information at their own pace. It also came to light that the use of web-based instruction improved students’ understanding in biology concepts, stimulated students’ interest and thinking, and was not a waste of instructional time. The study revealed that students could use web-based software without any difficulties, the use of web-based instruction was not boring, the use of web-based instructions individualised learning and finally, the use of web-based technology for biology instruction was not time-consuming.

A purposive sampling technique of the non-probability sampling procedure was used to select the pre-service science teachers in an intact class. Pre-Service Science Teachers’ Hydrocarbon Concept Diagnostic Test and Pre-Service Science Teachers’ Hydrocarbon Concept Achievement Test were the research instruments used to collect the data. The instruments were pilot-tested at St. Ambrose College of Education and the reliability index found to be 0.75 for the pre-intervention test and 0.78 for the post-intervention test.

Results indicated the existence of a consistency between pictorial representations, providing indications that this kind of representation could be used as a consistent tool in order to study students’ understanding of the contribution of quantum number characteristics in the configuration of the atomic structure.
