Background If we are to effect change in teacher practices and decision making regarding instruction, college preparation, and career success in engineering, then knowledge of teachers' beliefs and expectations about engineering needs to be understood. Purpose (Hypothesis ) The primary purpose was to develop a statistically reliable survey instrument to document teachers' beliefs and expectations about pre‐college engineering instruction, college preparation, and career success in engineering, called the Engineering Education Beliefs and Expectations Instrument (EEBEI), and to compare teachers' views. Design /Method Using two samples of teachers, EEBEI was established as a statistically reliable survey and was used to examine the beliefs and expectations of Project Lead the Way (PLTW) and non‐PLTW teachers. The results were used to further examine teachers' decisions in advising fictional students (described in vignettes) with varying academic and socioeconomic profiles. Results High school STEM teachers report their instruction was influenced by students' interests, family background, and prior academic achievement. Comparisons between PLTW and non‐PLTW teachers revealed that non‐PLTW teachers agreed more strongly that an engineer must demonstrate high scholastic achievement in math and science whereas PLTW teachers were more likely to report that science and math content was integrated into engineering activities. Although teachers report that students' socioeconomic status was not influential when asked explicitly, it did influence situated decision‐making tasks using fictional student vignettes. Conclusions Findings address challenges of STEM integration and reveal conflicting purposes of K‐12 engineering education as being for a select few or to promote technological literacy for all students, which affects recruitment, instruction, and assessment practices. 相似文献

Robotics and automation provide potentially paradigm shifting improvements in the way materials are synthesized and characterized, generating large, complex data sets that are ideal for modeling and analysis by modern machine learning (ML) methods. Nanomaterials have not yet fully captured the benefits of automation, so lag behind in the application of ML methods of data analysis. Here, some key developments in, and roadblocks to the application of ML methods are reviewed to model and predict potentially adverse biological and environmental effects of nanomaterials. This work focuses on the diverse ways a range of ML algorithms are applied to understand and predict nanomaterials properties, provides examples of the application of traditional ML and deep learning methods to nanosafety, and provides context and future perspectives on developments that are likely to occur, or need to occur in the near future that allow artificial intelligence to make a deeper contribution to nanosafety. 相似文献

The role of artificial intelligence (AI) in material science and engineering (MSE) is becoming increasingly important as AI technology advances. The development of high-performance computing has made it possible to test deep learning (DL) models with significant parameters, providing an opportunity to overcome the limitation of traditional computational methods, such as density functional theory (DFT), in property prediction. Machine learning (ML)-based methods are faster and more accurate than DFT-based methods. Furthermore, the generative adversarial networks (GANs) have facilitated the generation of chemical compositions of inorganic materials without using crystal structure information. These developments have significantly impacted material engineering (ME) and research. Some of the latest developments in AI in ME herein are reviewed. First, the development of AI in the critical areas of ME, such as in material processing, the study of structure and material property, and measuring the performance of materials in various aspects, is discussed. Then, the significant methods of AI and their uses in MSE, such as graph neural network, generative models, transfer of learning, etc. are discussed. The use of AI to analyze the results from existing analytical instruments is also discussed. Finally, AI's advantages, disadvantages, and future in ME are discussed. 相似文献

This study developed a survey entitled Conceptions of Learning Engineering (CLE), to elicit undergraduate engineering students' conceptions of learning engineering. The reliability and validity of the CLE survey were confirmed through a factor analysis of 321 responses of undergraduate students majoring in electrical engineering. A series of ANOVA analyses revealed that students who preferred a classroom setting tended to conceptualize learning engineering as “testing” and “calculating and practicing,” whereas students who preferred a laboratory setting expressed conceptions of learning engineering as “increasing one's knowledge,” “applying,” “understanding,” and “seeing in a new way.” A further analysis of student essays suggested that learning environments which are student‐centered, peer‐interactive, and teacher‐facilitated help engineering students develop more fruitful conceptions of learning engineering. 相似文献

A survey incorporating qualitative measures of student self‐efficacy beliefs was administered to 1,387 first‐year engineering students enrolled in ENGR 106, Engineering Problem‐Solving and Computer Tools, at Purdue University. The survey was designed to identify factors related to students' self‐efficacy beliefs, their beliefs about their capabilities to perform the tasks necessary to achieve a desired outcome. Open‐ended questions prompted students to list factors affecting their confidence in their ability to succeed in the course. Students were then asked to rank these factors based on the degree to which their self‐efficacy beliefs were influenced. Gender trends emerged in student responses to factors that affect confidence in success. These trends are discussed in light of the categories identified by efficacy theorists as sources of self‐efficacy beliefs. The results presented here provide a useful look at the first‐year engineering experiences that influence students' efficacy beliefs, an important consideration in explaining student achievement, persistence, and interest. 相似文献
