Writing4practice in engineering courses: Implementation and assessment approaches

In this article, we analyze a two‐semester effort to integrate writing instruction into a multi‐disciplinary sophomore engineering design course in Northern Arizona University's College of Engineering and Technology. Specifically, we describe the programmatic implementation and assessment approach to evaluate whether student writing improved over the course of the semester. After discussing the reasons for taking a writing‐intensive approach to engineering, we analyze the results of a pre‐and post‐test administered over the span of an academic semester. Although the outcome of our assessment did not show significant improvement, we argue that writing instruction is important for increasing students’ overall learning skills. We conclude by pointing out several benefits and disadvantages of trying to assess writing improvement over two one‐semester periods.     

Multi-Method Evaluation of Instruction in Engineering Classes

Student evaluation of instruction in college and university courses has been a routine and mandatory part of undergraduate and graduate education for some time. A major shortcoming of the process is that it often relies exclusively on the opinions or qualitative judgments of students rather than the learning or transfer of knowledge that takes place in the classroom. To develop a more objective system of assessment, this research focused on a learning-centered approach to course work and teaching evaluation. Standardized testing tools were developed suitable for measuring the content knowledge of students in a representative group of undergraduate courses. Course evaluations were conducted using two systems of assessment: the traditional student questionnaire feedback system and one based on the learning-centered approach using a computer-based question bank and on-line testing. Significant performance differences were evident in pretest/posttest comparisons of student learning. Favorable ratings of instruction are reflected in opinions on student questionnaires. No relationship was demonstrated between learning and traditional course evaluation outcomes. Our hypothesis that the learning-centered approach provides information that is not available using the traditional student feedback system was supported.Support for this research was provided in part by Grant No. P116B981224-00 from the U.S. Department of Education, Fund for the Improvement of Post-Secondary Programs awarded to the University of North Carolina at Charlotte. The opinions expressed do not necessarily reflect the position or policy of the Department of Education, and no official endorsement should be inferred.     

The Use of Seven Simulation Games in a College Economics Course

This study investigated the impact of four student characteristics and the instructors on the relative abilities of a simulation-gaming method and the lecture-discussion method to increase the economic knowledge, retention of economic knowledge, and interest toward economics of college students enrolled in an introductory economics course. The study indicated that the relative effectiveness of the methods of instruction was influenced by the students’ pre-course economic knowledge, previous economic training, and scholastic abilities. While the limitations of the study should be considered, it was suggested that a student’s economic knowledge, previous training, and scholastic ability could be used to place the student in the appropriate introductory economics course section.     

The adult learner and performance in introductory economics,a personalized system of instruction

The primary goal of this study is to determine the effectiveness of the personalized system of instruction format which is currently utilized in the introductory economics course at Empire State College, State University of New York. It will attempt to determine if adult students working in a personalized instruction system can learn as much as students in conventional settings. The study will also explore the broader objective of explaining and predicting adult student performance in the introductory economics course. In addition, an analysis will be made of any patterns which have emerged in the level of learning and the types of competencies aquired by students.     

Environmental Education within a Science Course in the Initial Education of Primary Teachers

This paper describes an attempt to infuse an environmental dimension into a science course through which prospective primary teachers are trained. The innovation concerns teaching science concepts not in the context of the discipline, but within a context of everyday life, and as such the focus chosen was drinking water. In formulating the course, learners’ ideas about aspects of the issue were taken into account. The evaluation was based on a post‐course questionnaire. The main conclusions to be drawn from this evaluation is that the science knowledge learned through this approach helped students gain a better understanding of a variety of aspects which concern that issue. The majority of students appreciated such an integrated approach and thought the approach taken was more promising than the stereotypical one that they had been accustomed to up to that point.     

Faculty Views of Student Evaluation of College Teaching

The literature abounds with psychometric studies of course evaluation measures and articles debating the merits of student ratings of instruction, but little research has focused on faculty perceptions of this procedure. In the present study faculty perceptions are explored at a teachers' college where evaluation is carried out annually on a sample of courses. The sample includes 101 instructors who completed the research questionnaire. Faculty attitudes reflected a broad range of responses towards validity of student ratings, and their usefulness for improving instruction. Although overall attitudes were mildly positive, few instructors reported changing instruction as a result of student ratings. Moreover, few supported sending evaluation results directly to college administrators or publishing them for student consumption.     

Teaching philosophies guiding sexuality instruction in US colleges and universities

Teaching philosophies are central to the approach of pedagogical strategies but there has been little examination of discipline-specific teaching philosophies. This study addresses a significant gap in the literature by discussing the teaching philosophies of 122 instructors of sexuality courses. Sexuality education is unique compared to most disciplines due to the personal nature of the content, thus being more difficult for students and instructors to distance themselves from the course content. The teaching philosophies in this study conveyed two overarching approaches to sexuality instruction: the instructor’s perspective of the course and the approach of the sexuality instruction. Although teaching philosophies typically inform one’s practice of teaching and course content, this study proposes that sexuality education is intrinsically different than other areas of instruction despite the interdisciplinary backgrounds of college instructors.     

Projects in Undergraduate Engineering Education in America

A survey of engineering educators in the US was conducted to ascertain actual practice regarding the delivery of engineering projects in the curriculum. The survey focused only on project experiences carrying significant academic credit that are free-standing elements of the curriculum; that is, they are not associated with or part of a course. Inquiries covered: the degree to which such activities meet requirements for graduation, accreditation and/or professional licensure; the extent of involvement of off-campus professionals in the conduct of the project, and in its support and its evaluation and assessment; the size and make-up of student teams in such activities, and the preparation and evaluation techniques used for team efforts; and the degree to which faculty members act as advisors or teachers. This paper briefly describes what is meant generally by the project mode of instruction in engineering education in the US, and describes the breadth of pedagogy in the current delivery of engineering projects represented by the survey responses, and by the engineering education literature discussing project education. The paper is intended to provide a basis for the international exchange of ideas on how engineering project education is being presented in various nations. Current trends in US engineering education that affect project education are also highlighted for comparison with those in other countries.     

Implementation of a peer‐led team learning instructional approach in an undergraduate organic chemistry course

This study focuses on the implementation of a peer‐led team learning (PLTL) instructional approach for all students in an undergraduate organic chemistry course and the evaluation of student outcomes over 8 years. Students who experienced the student‐centered instruction and worked in small groups facilitated by a peer leader (treatment) in 1996–1999 were compared with students who experienced the traditional recitation section (control) in 1992–1994. Quantitative and qualitative data show statistically significant improvements in student performance, retention, and attitudes about the course. These findings suggest that using undergraduate leaders to implement a peer‐led team learning model that is built on a social constructivist foundation is a workable mechanism for effecting change in undergraduate science courses. © 2002 Wiley Periodicals, Inc.

A responsive evaluation of a graduate seminar

It was in the late sixties when the formal evaluation of teachers and their courses by students in their classes first became routinized at the University of Illinois at Urbana. Students and teachers alike were told that the purpose of the evaluations was to improve college teaching. The instruments were advocated on the basis of being vehicles for student expression in the higher education process and as part of the whole move towards accountability. In practice, however, the evaluations were used by department heads or chairpersons as part of the basis for decisions about salary, retention, promotion, and tenure. Thus, the need for a new approach to course evaluation, concentrating on improving instruction was recognized. This paper is an account of a course evaluation using the responsive approach.     

Moving the classroom to the computer lab: Can online learning with in-person support improve outcomes in community colleges?

Colleges are experimenting with integrating technology into the classroom to improve student learning and reduce costs. While fully online models appear to have negative effects on student learning compared to in-person instruction, there is less evidence about models that blend elements of online and in-person instruction. In this study, I estimate the effect of adopting a blended approach to teaching called the emporium model in which students complete online work in an on-campus lab with instructors onsite to assist. Using a triple difference identification strategy, I find that using the emporium model compared to traditional instruction in remedial math courses in a state community college system reduces course pass rates, retention, and degree attainment. Effects were generally consistent across all three levels of remediation, suggesting there was little variation by students’ incoming placement test score.     

Educational Research in an Introductory Astronomy Course

The lecture is a common method used in college instruction, but many teachers are questioning its effectiveness. For this study, two successive spring semester sections of introductory astronomy for non-science majors were studied. The spring 1999 semester was the instructor's first attempt to incorporate innovative instructional techniques to include hands-on, minds-on instruction within the lecture setting. The educational research involved classroom observations, personal interviews, and pre-instruction/post-instruction administration of the Texas Attitude Survey and the Astronomy Diagnostic Test. During the spring 2000 semester, the instructor modified instruction to respond to student concerns from the previous semester. Student scores for the second course showed significant improvement in astronomy content and the institutional course survey, but not in student self-efficacy.     

Student Evaluation of Instruction: In the New Paradigm of Distance Education

Distance education has experienced soaring development over the last decade. With millions of students in higher education enrolling in distance education, it becomes critically important to understand student learning and experiences with online education. Based on a large sample of 11,351 students taught by 1,522 instructors from 29 colleges and universities, this study investigates the factors that impact student evaluation of instruction in distance education, using a two-level hierarchical model. Key findings reveal that in a distance education setting, gender and class size are no longer significant predictors of quality of instruction. However, factors such as reasons for taking the course, student class status and instructor’s academic rank have a significant impact on student evaluation of learning and instruction. Findings from this study offer important implications for institutional administrators on utilizing the evaluation results and on developing strategies to help faculty become effective online instructors.     

Using Blogs to Identify Misconceptions in a Large Undergraduate Nutrition Course

We describe two iterations of the design, development, implementation and evaluation of small online activity and reflection blogging groups into a large undergraduate lecture course in nutrition. Our goal was to promote student learning and conceptual change through reflection and interaction in blog conversations. We found the blog conversations to be highly useful to the instructors as a source of data on student understandings and misconceptions of course topics. These misconceptions could then be addressed with further instruction. We found that, even with initial training, graduate teaching assistants needed significant guidance in facilitation strategies and that finding the ideal balance between structure and autonomy is a design challenge.     

Personalizing instruction in business and economics

This paper examines personalized instruction in business and economics at the Long Island Learning Center, Empire State College, State University of New York. In this mode of instruction the course of study is tailored to the individual background, interests, needs, and abilities of the student. Learning activities often incorporate some aspect of the student's academic or professional experience. Most of the students have fairly well-established goals, are highly motivated, have jobs, and have enjoyed considerable success in their fields. Various examples are provided that indicate how the subject matter gains relevance when basic theoretical concepts are applied to real-life situations.     

Effects of a Pre‐service Teacher Preparation Programme on Effective Instruction

A quasi‐experimental, treatment‐control group investigation was designed to test the effects of a pre‐service training course on effective instruction. Research findings from teacher effects research and cognitive strategy instruction were translated into two direct instructional models: one model for explicit or well‐structured skills and one model for implicit skills or higher‐level thinking strategies. Following a course on effective instruction from their teacher educators, student teachers implemented standardised lessons to apply selected research‐derived teaching behaviours and to increase pupil engagement rates. Based on trained observers’ pre‐and post‐training classroom observations, a significant treatment effect was found for student teachers’ teaching behaviours regarding effective instruction and for pupil engagement rates. Ratings from supervising teachers also showed that the student teachers who participated in the course on effective instruction used the recommended instructional skills after completion of the course significantly better than prior to the course.     

Promoting understanding of chemical bonding and spontaneity through student explanation and integration of ideas

This article explores the effectiveness of intervention discussion sections for a college general chemistry course designed to apply research on student preconceptions, knowledge integration, and student explanation. Two interventions, on bond energy and spontaneity, were tested and intervention student performance was compared with that of a control group that did not use the experimental pedagogy. Results indicate that this instruction, which identifies students' initial conceptions and integrates those ideas into class discussion, leads to enhanced conceptual understanding. The intervention group outperformed the control group on a written course midterm, the thermodynamics portion of a standardized American Chemical Society examination, and an in‐depth interview. In interviews, the intervention group students explained the energetics of bond breaking and formation at a more sophisticated level than did the control students. In contrast, control students were more tenuous in their thinking, tended to contradict themselves more when discussing bond energy, and harbored more misconceptions about spontaneity. © 2002 Wiley Periodicals, Inc.

建构主义教学模式在理论经济学课程中的运用与思考

建构主义教学模式是以学生为中心、通过合作与发现学习的非支配模式。这种教学模式对内容抽象的理论经济学课程有一定的帮助，但又会与理论经济学课程特点有着不可避免的矛盾。所以，在理论经济学课程中，应建立将建构主义教学手段融入到传统教学方式中的半推动型教学模式：教师与学生合作设计，教师给予明确而详尽的教授与讲解，同时对学生的学习参与给以明确的引导。     

STUDENT EVALUATION OF INSTRUCTION: PERCEPTIONS OF COMMUNITY COLLEGE STUDENTS,FACULTY, AND ADMINISTRATORS

The purpose of this study was to compare the opinions of students, teachers, and administrators relative to student evaluation of instruction in selected community colleges. While important educational decisions in community colleges are made on the basis of students’ evaluations (as in retention, promotion, tenure, and pay), little has been accomplished in testing the assumptions behind student evaluation of instruction. The student evaluation process assumes that students are honest, serious, and evaluate instruction, not some incidental activity.

A 25‐item Student Evaluation Process Scale was completed by 607 students, 130 faculty, and 45 administrators in five Illinois community colleges. Findings revealed little significant differences in the opinions of students regarding evaluation of instruction based on variables of sex, age, school location, student type (transfer or occupational), and class standing. There were little significant differences in faculty opinion and within the administrative groups based on selected variables. There were significant differences when the opinions of students, faculty, and administrators were compared. Students and faculty tended to agree with those items that questioned the objectivity of student evaluation of instruction. Administrators and students tended to agree with items reflecting the seriousness with which students evaluate instruction. Faculty and administrators indicated that student evaluation of instruction impacted faculty members’ instructional performances. Neither students, faculty, nor administrators supported the concept of merit pay tied to student evaluation of instruction.

The role of student evaluation of instruction in a faculty evaluation system must be investigated. A variety of groups should participate in this investigation.
