Excellence in Engineering Education: Views of Undergraduate Engineering Students

The purpose of this study was to understand the views and perceptions of engineering undergraduate students on engineering education. The method of content analysis was used to analyze the language used by engineering undergraduate students, and to extract the underlying common factors or perceived characteristics of “Excellence in Engineering Education.” These common factors were then used to identify and compare the similarities and differences in views between engineering students and perspectives from three types of stakeholders in the field. Forty‐seven undergraduate engineering students (17 females and 30 males) participated voluntarily in this study to answer four individual questions and ten group questions. The results showed that students strongly emphasized the importance of their own roles in the educational system and the value of instructional technology and real work examples in enhancing the quality of engineering education. The implications of the research results on excellence in engineering education are discussed.     

First Steps in Understanding Engineering Students' Growth of Conceptual and Procedural Knowledge in an Interactive Learning Context

The development of procedural knowledge in students, i.e., the ability to effectively solve domain problems, is the goal of many instructional initiatives in engineering education. The present study examined learning in a rich learning environment in which students read text, listened to narrations, interacted with simulations, and solved problems using instructional software for thermodynamics. Twenty‐three engineering and science majors who had not taken a thermodynamics course provided verbal protocol data as they used this software. The data were analyzed for cognitive processes. There were three major findings: (1) students expressed significantly more cognitive activity on computer screens requiring interaction compared to text‐based screens; (2) there were striking individual differences in the extent to which students employed the materials; and (3) verbalizations revealed that students applied predominantly lower‐level cognitive processes when engaging these materials, and they failed to connect the conceptual and procedural knowledge in ways that would lead to deeper understanding. The results provide a baseline for additional studies of more advanced students in order to gain insight into how students develop skill in engineering.     

建筑工程快速估价的一种模型及应用

应用模糊数学的理论和计算方法,建立了一种建筑工程造价的快速估算模型：首先拟定建筑工程的特征元素,建立典型工程的特征值矩阵,然后通过公式转换,建立典型工程隶属度矩阵并确定各典型工程与拟建工程的贴近度,最后由贴近度最大的典型工程来计算拟建工程造价。实例应用表明,该模型具有优越性。

包装工程专业本科教育中产学研的结合

包装工程本科教育中产学研相结合的问题,存在不同的层次,侧重点也不相同。包装工程本科教育与包装产业结合的主要方式有认识实习、生产实习、设计大赛、校企科研合作、课外导师制、开设与生产实践相关的选修课、生产实践人员进课堂、设置专项奖助学金等;学校教育之间的合作也是产学研结合的重要组成部分,学生的思想素养以及教师的职业道德,对产学研结合的实践效果和可持续发展具有直接影响;包装工程本科教育还需与科学研究相结合,以培养学生的科学思维能力,包装工程专业教师也应不断提高科研水平,以满足持续发展的本科教育需求。

Gender Differences in Elements of the Undergraduate Experience that Influence Satisfaction with the Engineering Major and the Intent to Pursue Engineering as a Career

Background Groups within and outside of educational institutions are interested in factors that influence satisfaction among students enrolled in the engineering major as well as elements within the college environment that shape students' intentions to work in engineering in the future and whether these elements differ by gender. Purpose (Hypothesis ) This study identified gender differences on indicators of the undergraduate experience including faculty‐related and student‐related variables as well as measures of satisfaction with the institutional environment that are related to satisfaction with the engineering major and intent to pursue a career in engineering ten years from now. Design /Method The mixed methods approach used for this investigation involved nine institutions with engineering undergraduate degree programs. An online questionnaire was administered to undergraduate students enrolled in engineering. Qualitative data was collected through focus group interviews with students at each of the nine participating institutions. Results Findings reveal that satisfaction with the engineering major does not translate directly to pursuing a career in engineering, particularly among women. In terms of elements of the undergraduate experience, some types of interactions with faculty and peers have both short‐ and long‐term impacts on interest in engineering as a major and as a career. Conclusions Creating learning environments that emphasize care and respect for students as well as overseeing student interaction during group work can make a difference in students' satisfaction in the engineering major and in interest in engineering as a career, particularly for women.     

Numerical Methods in Engineering and Science

In our daily lives, we often need to identify individuals whose longitudinal behavior is different from the behavior of those well-functioning individuals, so that some unpleasant consequences can be avoided. In many such applications, observations of a given individual are obtained sequentially, and it is desirable to have a screening system to give a signal of irregular behavior as soon as possible after that individual’s longitudinal behavior starts to deviate from the regular behavior, so that some adjustments or interventions can be made in a timely manner. This article proposes a dynamic screening system for that purpose in cases when the longitudinal behavior is univariate, using statistical process control and longitudinal data analysis techniques. Several different cases, including those with regularly spaced observation times, irregularly spaced observation times, and correlated observations, are discussed. Our proposed method is demonstrated using a real-data example about the SHARe Framingham Heart Study of the National Heart, Lung and Blood Institute. This article has supplementary materials online.
