To help this journey to evidence, robust qualitative and quantitative research can help decisionmakers identify more promising approaches that provide value for money. In the context of the utilisation of scarce resources, an important source of evidence commonly used in health and social care research is an understanding of the economic impact of intervention choices. However, there are currently very few examples where these methodologies have been used to improve the evaluation of education interventions. In this paper we describe the novel use of an economic analysis of educational interventions (EAEI) approach to understand both the impact and the cost of activities in the evaluation of a formative assessment implementation project (FAIP) designed to improve teachers’ understanding and use of formative assessment strategies. In addition to utilizing a mixed method quasi-experimental design to explore the impact on learner wellbeing, health utility and attainment, we describe the use of cost-consequence analysis (CCA) to help decisionmakers understand the outcomes in the context of the resource costs that are a crucial element of robust evaluations. We also discuss the challenges of evaluating large-scale, universal educational interventions, including consideration of the economic tools needed to improve the quality and robustness of these evaluations. Finally, we discuss the importance of triangulating economic findings alongside other quantitative and qualitative information to help decisionmakers identify more promising approaches based on a wider range of useful information. We conclude with recommendations for more routinely including economic costs in education research, including the need for further work to improve the utility of economic methods.","PeriodicalId":11472,"journal":{"name":"Education Sciences","volume":"4 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142208692","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 intervention involved 24 in-service English as a Foreign Language (EFL) teachers who engaged in crafting activities and assessments using researcher-designed prompts. Utilizing a mixed-methods approach, the researchers assessed the participants’ ChatGPT integration proficiency through a custom-designed assessment tool aligned with the technological pedagogical content knowledge framework. The eight-week intervention introduced educators to various applications of ChatGPT in EFL teaching, including lesson planning. A quantitative analysis revealed statistically significant improvements in the teachers’ ChatGPT integration proficiency across all measured dimensions. The qualitative findings highlight the perceived benefits, challenges, and future prospects of ChatGPT in EFL education. While the practical significance of the improvement was modest, the results suggest that the guided integration of generative chatbots can bolster teachers’ ability to leverage this technology appropriately. This study contributes to the limited body of empirical research on integrating large language models into teaching and offers insights into the practical applications and challenges of using ChatGPT in EFL contexts.","PeriodicalId":11472,"journal":{"name":"Education Sciences","volume":"12 7 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142208664","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}

Learning objectives and questions on mid-term exams for four semesters of General Chemistry I (two traditional semesters and two guided inquiry semesters) were analyzed by the Cognitive Process and Knowledge dimensions of Bloom’s revised taxonomy. The results of this comparison showed the learning objectives for the guided inquiry semesters had a higher proportion of Conceptual and Understand with a corresponding decrease of Factual, Procedural, Remember and Apply learning objectives. On mid-term exams, the proportion of Remember, Understand, Analyze/Evaluate, Factual, and Conceptual questions increased. We found that guided inquiry learning objectives and mid-term exam questions are more conceptual than traditional courses and may help explain how active learning improves equity in introductory chemistry.","PeriodicalId":11472,"journal":{"name":"Education Sciences","volume":"18 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142208666","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}

Richard, Shelby Cosner","doi":"10.3390/educsci14090944","DOIUrl":"https://doi.org/10.3390/educsci14090944","url":null,"abstract":"Throughout the globe, there is growing attention being paid to issues of equity and efforts to produce more equitable student learning outcomes in schools, and much of the scholarship internationally has begun to center school leaders as key drivers of more equitable conditions. Indeed, in the United States, persistent inequities in education have highlighted the need for K-12 principals who can effectively support diverse students. Effective leader preparation and development, particularly with a focus on equity, is crucial, as it equips school leaders with the knowledge and skills to create inclusive and equitable learning environments. U.S.-based research highlights that high-quality, equity-centered preparation programs can significantly impact student outcomes, emphasizing the importance of integrating equity-focused training in leadership development. However, we know less about the design of high-quality preparation programs oriented around equity, and scholars have noted that current programs are often ill-equipped to prepare equity-centered leaders. Therefore, this study provides an integrative review of the U.S.-based equity-centered principal preparation literature to extract learnings from several types of publications, including descriptive and empirical studies, literature reviews, and conceptual essays. This study provides insights into four key elements of equity-centered principal preparation and development: program vision, curriculum, pedagogy, and assessment. This review consolidates insights from the existing literature into a single, accessible article, offering valuable learnings for program faculty, others who prepare school principals, and researchers focused on equity-centered preparation. Additionally, while centered on the U.S. context, this review is likely to be of value to leadership preparation and development programs in other national contexts, particularly those that have more recently begun to form.","PeriodicalId":11472,"journal":{"name":"Education Sciences","volume":"7 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142208663","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}

Experiment 1 investigated learning to play a series of piano clips of varying complexity. Results demonstrated improved learning efficiency with imitative practice compared to no practice. Experiment 2 featured a paper-folding task, and results indicated that real practice led to significantly greater learning than no practice. Furthermore, a significant interaction was found with gender and practice, where females learned best with both real and imitative practice, but males did not benefit from these interventions. However, males outperformed females in the no practice condition. Overall, we found benefits of practice versus no practice for both tasks. However, the most effective type of practice was dependent upon the task: imitative practice for piano playing, and real practice for paper folding.

Inclusive education has been proposed as a possible framework that can promote positive educational outcomes; however, in South Africa, there has not been enough attention paid to inclusive education in ECD especially focusing on children with CCNs. The study therefore explored the perceptions of parents of children with CCNs and early childhood development teachers on inclusive education. Semi-structured interviews and a focus group were conducted with 8 ECD teachers and 8 parents of children with CCNs, who were purposively selected. Data were imported into NVivo 1.5 software and analysed using an inductive thematic analysis approach. Findings from the study revealed the following themes: i. Perceived benefits of inclusive education; ii. Preference for special needs education; iii. Shortcomings of special needs education in addressing the needs of learners with CCNs; iv. Factors informing school placement; v. Communication as a barrier to learning, teaching and socializing; vi. The need for disability conscientization. Although both parents and teachers of learners with CCNs acknowledge the value of inclusive education in facilitating access to education, they have a mistrust of inclusive education because of fear of stigma, discrimination, exclusion, bullying and exclusionary teaching practices. While they preferred special education, they acknowledged the gaps in teacher’s knowledge on communication disorders, training of teachers, teaching aids and assistive devices. Educating a child with a disability is expensive because of other additional costs, especially transportation.","PeriodicalId":11472,"journal":{"name":"Education Sciences","volume":"17 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142208689","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}

Teachers of all subjects are expected to pass on key digital competencies along with subject-related knowledge to facilitate students’ employability and navigation in a society characterized by the impact of digital technology in all areas of life. However, several studies have shown that there is still a lack of integration of digital competencies in teacher training programs. Hence, to add to these previous studies, this paper aims to find and explore strategies and measures to equip secondary-level pre-service teachers with digital competencies and support them in professionally promoting their students’ digital skills. This happens by investigating what advanced pre-service teachers at a large European university miss and suggest changing to become more confident in promoting digital competencies at secondary school levels (K5–K12). In this context, the authors deepened a previously conducted university-wide survey among advanced secondary-level pre-service teachers through two focus groups to sharpen insights into challenges and good practices from the perspective of pre-service teachers. A thematic analysis of these focus groups confirmed the presumption that most pre-service teachers are keen on actively acquiring relevant digital competencies and gave insights into how they wish to have digital skills integrated into their studies. Additionally, it became evident that even though pre-service teachers can acquire several digital skills through self-study, they longed for collaboration and guidance to reach a professional level for “teaching” them to their students.","PeriodicalId":11472,"journal":{"name":"Education Sciences","volume":"8 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142208672","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}

Grounded in an ecological perspective on teacher agency and emotional vulnerability, the study investigates how and why the teacher exercised agency in navigating her emotional challenges and adapting to the virtual teaching environment. Data were collected from various sources, including interviews, observations, field notes, and artifacts, for three years. The findings showed that the intricate connection between the teacher’s multiple and dynamic emotions, beliefs, and concurrent working environments significantly influences her engagement in digital teaching practices. Furthermore, the teacher’s emotional vulnerability in virtual teaching facilitated her engagement in reflective and action-oriented practices, leading to a more proactive approach to exploring and implementing alternative teaching methods online. The findings highlight the interplay between emotions, agency, and identity development, emphasizing the importance of experiencing, understanding, negotiating, and expressing emotions to discover potential alternative teaching resources and methods in ever-changing teaching environments. This study provides insights into how teachers can leverage their emotions and exercise teacher agency to enhance their professional growth and adaptability in digital learning environments.","PeriodicalId":11472,"journal":{"name":"Education Sciences","volume":"46 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142208671","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}
