The impact of student misconceptions on student persistence in a MOOC     

Chen Chen  Gerhard Sonnert  Philip M. Sadler  Dimitar Sasselov  Colin Fredericks 《科学教学研究杂志》2020,57(6):879-910

Massive Online Open Courses (MOOCs) provide opportunities to learn a vast range of subjects. Because MOOCs are open to anyone with computer access and rarely have prerequisite requirements, the range of student backgrounds can be far more varied than in conventional classroom-based courses. Prior studies have shown that misconceptions have a huge impact on students' learning performance; however, no study has empirically examined the relationship between misconceptions and learning persistence. This study of 12,913 MOOC-takers examines how students' misconceptions about the upcoming course material affect course completion. Using a survival analysis approach, we found that, controlling for the score in a pre-course test, students holding more misconceptions had a higher dropout rate at the start of the course, an effect that diminished over time. Other student variables were found to have a positive impact on survival that persisted throughout the entire course: U.S. location, higher age, an intention to complete, better English skills, prior familiarity with the subject, motivation to earn a certificate, and score and time spent on the previous problem set (homework). By contrast, student gender, education level, number of previous MOOCs completed, and motivation to participate in online discussion forums did not affect survival.  相似文献   

Concept Proliferation as an Educational Good: Epistemic Injustice,Conceptual Revolutions,and Human Flourishing     

A. C. Nikolaidis 《Educational theory》2020,70(4):463-482

This article presents a pedagogical approach for disrupting epistemic injustice. In it, A. C. Nikolaidis first demonstrates that different forms of epistemic injustice — testimonial, hermeneutical, and contributory — are the result of limited or distorted conceptual resources and then argues that concept proliferation can be a promising educational means for overcoming such limitations and distortions. Concept proliferation involves a combination of increasing exposure to diverse, especially marginalized, concepts and providing students with necessary critical tools for questioning harmful and erroneous concepts. Concept proliferation is beneficial for both individual students and society at large. It liberates students from the confines of harmful concepts that limit their self-understanding, but also provides them with skills necessary to challenge hegemonic concepts that distort collective (social) understanding and contribute to epistemic and systemic injustice.  相似文献   

Business Intelligence Capabilities and Firm Performance: A Study in China     

《International Journal of Information Management》2021

The development of artificial intelligence (AI) technology expands the boundary of business practice, inducing the emergence and application of business intelligence (BI) that has promoted the transformation of information techniques to optimize business decision and operation. However, there is a lack of theoretical consensus and measurement of the technology embedded in BI at present. This study exploratively develops the Sense-Transform-Drive (STD) conceptual model of BI based on dynamic capabilities theory and organizational evolutionary theory to explain the core BI capabilities. By using factoring analysis and structural equation modeling analysis, we extract the latent constructs and empirically verify the validity of the STD model and further examine the correlation and mode of interaction of the three core BI capabilities and the impact of BI application on firm performance in the real economy with a sample contextual to Chinese business practices. The study results show that there are direct and high-intensity cumulative positive effects among the structural components of the STD conceptual model and BI-related dynamic capabilities can enhance operating efficiency and firm performance.  相似文献   

Professional development design considerations in climate change education: teacher enactment and student learning     

Andrea Drewes  Joseph Henderson  Chrystalla Mouza 《International Journal of Science Education》2018,40(1):67-89

Climate change is one of the most pressing challenges facing society, and climate change educational models are emerging in response. This study investigates the implementation and enactment of a climate change professional development (PD) model for science educators and its impact on student learning. Using an intrinsic case study methodology, we focused analytic attention on how one teacher made particular pedagogical and content decisions, and the implications for student’s conceptual learning. Using anthropological theories of conceptual travel, we traced salient ideas through instructional delivery and into student reasoning. Analysis showed that students gained an increased understanding of the enhanced greenhouse effect and the implications of human activity on this enhanced effect at statistically significant levels and with moderate effect sizes. However, students demonstrated a limited, though non-significant gain on the likely effects of climate change. Student reasoning on the tangible actions to deal with these problems also remained underdeveloped, reflecting omissions in both PD and teacher enactment. We discuss implications for the emerging field of climate change education.  相似文献

Comparing balance and inverse methods on learning conceptual and procedural knowledge in equation solving: a cognitive load perspective     

Bing Hiong Ngu  Huy Phuong Phan 《Pedagogies: An International Journal》2016,11(1):63-83

We examined the use of balance and inverse methods in equation solving. The main difference between the balance and inverse methods lies in the operational line (e.g. +2 on both sides vs ?2 becomes +2). Differential element interactivity favours the inverse method because the interaction between elements occurs on both sides of the equation for the balance method but only on one side of the equation for the inverse method. In an experimental study, 63 students (mean age = 13) were randomly allocated to either balance or inverse group to undertake a pre-test, study an instruction sheet, complete acquisition equations, sit for a post-test and a concept test. Procedural knowledge was assessed on performance on practice equations and post-test, whereas conceptual knowledge was assessed on performance on the concept test. The inverse group outperformed the balance group on practice equations but not the post-test. Both the balance and inverse groups scored higher on the inverse concept test than the balance concept test. Positive association between performance on procedural knowledge and performance on conceptual knowledge was found for the inverse group but not the balance group. Overall, the evidence obtained indicates a number of educational implications for implementation.  相似文献
