High-throughput, cost-effective, and portable devices can enhance the performance of point-of-care tests. Such devices are able to acquire images from samples at a high rate in combination with microfluidic chips in point-of-care applications. However, interpreting and analyzing the large amount of acquired data is not only a labor-intensive and time-consuming process, but also prone to the bias of the user and low accuracy. Integrating machine learning (ML) with the image acquisition capability of smartphones as well as increasing computing power could address the need for high-throughput, accurate, and automatized detection, data processing, and quantification of results. Here, ML-supported diagnostic technologies are presented. These technologies include quantification of colorimetric tests, classification of biological samples (cells and sperms), soft sensors, assay type detection, and recognition of the fluid properties. Challenges regarding the implementation of ML methods, including the required number of data points, image acquisition prerequisites, and execution of data-limited experiments are also discussed.  相似文献   

Pre-service English as a foreign language teachers' perceptions of the relationship between multiple intelligences and foreign language learning     

Perihan Savas 《Learning and individual differences》2012,22(6):850-855

The relationship between intelligence, language, and learning is a challenging field of study. One way to study how this relationship occurs and works is to investigate the perceptions of advanced language learners. Therefore, this paper reports a study that was conducted to explore 160 pre-service English language teachers' perceptions about which type(s) of multiple intelligence(s) play a role in foreign language learning. The findings of the study indicated that virtually all participants (97%) agreed on making use of all intelligence types in the process of foreign language learning and linguistic intelligence alone does not guarantee success in learning a foreign language. The results of the study also illustrate that multiple intelligences and foreign language learning have an ongoing, complex, and interactive relationship. Finally, a foreign language learning discipline MI profile is suggested.  相似文献   

Understanding critical race theory as a framework in higher educational research     

Gokhan Savas 《British Journal of Sociology of Education》2014,35(4):506-522

This paper reviews the existing literature to discuss how critical race theory has been applied as a theoretical framework to higher educational research in the United States and what its contributions are. To provide necessary context, I will discuss race and racism in the United States, the background of US higher education in relation to race, the emergence of critical race theory and its application in US higher education.  相似文献   

A Multilevel Analysis of Students’ Science Achievements in Relation to their Self-Regulation,Epistemological Beliefs,Learning Environment Perceptions,and Teachers’ Personal Characteristics

This study adopted a cross-sectional and correlational research design in an attempt to add our understanding of student- and teacher-level factors that help explain variability in students’ science achievement to the existing literature. More specifically, the present article examined students’ science achievement in relation to their constructivist learning environment perceptions, epistemological beliefs, and self-regulation as well as their science teachers’ characteristics. Data were gathered from both 137 science teachers and their 3281 seventh grade students via administering self-report questionnaires. Hierarchical linear modeling (HLM) analysis was conducted to analyze the two-level data (student level and teacher level). Students’ learning environment perceptions, epistemological beliefs, achievement goals, and self-regulation constituted student-level data while teachers’ self-efficacy, achievement goals, and epistemological beliefs constituted teacher-level data. The findings indicated that students’ constructivist learning environment perceptions were significant predictors of their science achievement. Additionally, students with sophisticated epistemological beliefs appeared to be more successful in science. Also, performance avoidance goals were negatively related to science achievement. Among teacher-level variables, teachers’ self-efficacy and sophisticated epistemological beliefs were found to be positively linked to students’ science achievement.  相似文献   

First‐year secondary school mathematics students’ conceptions of mathematical proofs and proving     

Savas Basturk 《Educational studies》2010,36(3):283-298

The aim of this study is to investigate students’ conceptions about proof in mathematics and mathematics teaching. A five‐point Likert‐type questionnaire was administered in order to gather data. The sample of the study included 33 first‐year secondary school mathematics students (at the same time student teachers). The data collected were analysed and interpreted using the methods of qualitative and quantitative analysis. The results have revealed that the students think that mathematical proof has an important place in mathematics and mathematics education. The students’ studying methods for exams based on imitative reasoning which can be described as a type of reasoning built on copying proof, for example, by looking at a textbook or course notes proof or through remembering a proof algorithm. Moreover, they addressed to the differences between mathematics taught in high school and university as the main cause of their difficulties in proof and proving.  相似文献
