Teaching Time Savers: The Exam Practically Wrote Itself!, Michael E. Orrison Jr.

All HMC Faculty Publications and Research

When I first started teaching, creating an exam for my upper division courses was a genuinely exciting process. The material felt fresh and relatively unexplored (at least by me), and I remember often feeling pleasantly overwhelmed with what seemed like a vast supply of intriguing and engrossing exam-ready problems. Crafting the perfect exam, one that was noticeably inviting, exceedingly fair, and unavoidably illuminating, was a real joy.

This paper describes exercises developed to improve first year students' computer literacy through more learner-centered engagement. Exercises are designed to support learner-centered goals of independent and responsible learners, appropriate breadth and depth of content, teacher as facilitator, and assessment woven into learning. Exercise topics include purchase of a personal computer, basic logic via spreadsheets, an annotated bibliography built with electronic resources, and an integrated assignment customized by and for each student.

Teaching Time Savers: Is Homework Grading On Your Nerves?, Lisette G. De Pillis, Michael E. Orrison Jr.

All HMC Faculty Publications and Research

You have probably heard it said that we learn mathematics best when we do mathematics, or that mathematics is not a spectator sport. For most of our students, this means that their mathematics courses will involve a fair amount of homework. This homework is often used to evaluate individual student progress, but it can also be used, for example, as a catalyst for discussion, to emphasize a point made in class, and to identify common misunderstandings throughout the class as a whole. There is, however, the matter of grading homework.

Teaching Time Savers: Some Advice On Giving Advice, Michael E. Orrison Jr.

All HMC Faculty Publications and Research

There are always a lot of questions that need to be answered at the beginning of a course. When are office hours? What are the grading policies? How many exams will there be? Will late homework be accepted? We have all seen the answers to these sorts of questions form the bulk of a standard course syllabus, and most of us feel an obligation (and rightly so) to provide such information.

Teaching Time Savers: Style Points, Michael E. Orrison Jr.

All HMC Faculty Publications and Research

When I began as an assistant professor, I had a pretty good sense of how much time it would take for me to prepare for each class. After a few conversations with my new colleagues, I even had a good sense of how much time I should devote to tasks like office hours and committee work. Somewhere in the middle of grading my first exam, though, it became painfully clear that I had underestimated the amount of time I would need to grade exams!

Teaching Time Savers: A Recommendation For Recommendations, Michael E. Orrison Jr.

All HMC Faculty Publications and Research

I admit it — I enjoy writing recommendation letters for my students. I like
learning about their hopes and dreams, where they have been and where they want to go. A recommendation letter is an opportunity to remind myself how much my students can grow while they are in college, and how much I have grown as an instructor, advisor, and mentor.

How Have Teachers Affected The Disinterest Towards Mathematics?, Amy Brown

Senior Honors Projects

In our school system today there is a collective disinterest and lack of enthusiasm towards mathematics as a whole. This apathy is prevalent as early as elementary school and continues through higher education. It is disheartening that so many students avoid mathematics because of their misconception that it is too difficult and has little value in their future. How well prepared are our teachers to deal with this? I began my research by looking at the past perceptions of mathematics and how the reform movement has changed this perspective. I also looked at the changing standards and how the Principles …

Journey To The Center Of The Core: Computers And The Internet In The Core Curriculum, Jorge Pérez, Meg C. Murray

Faculty Articles

Computers, digitalization and the Internet have transformed modern society. Commerce, education, communication and socialization will never be the same. Surprisingly, many universities do not require a computing course in the core curriculum. Critical information technology (IT) competencies are often taken for granted, to the detriment of students who lack computing and Internet skills. This paper describes an initiative undertaken by a computer science and information systems department to assess and remediate IT skills needed by all university students, regardless of major. The project is evolving along several dimensions: identification of discipline-independent IT competencies, assessment of IT skills among current and …

Studying The Performance Of A Firewall In Network Courses, José M. Garrido

Faculty Articles

This paper presents a simple simulation model of a firewall to derive several performance metrics and briefly argues on the importance and value of modeling and simulation in courses that study various aspects of perimeter defense in network security.

The simulation model mentioned previously is part of an effort by faculty of our department to develop a multi-disciplinary repository of computational models that includes object-oriented discrete-event simulation models. One of the goals of this repository is to build resources that help educate students of computer science, software engineering, and information technology, in modeling and information security.

In August 2004, we had the opportunity to travel to Jamaica to lead a pilot workshop for Jamaican high school math teachers. The workshop focused on the importance of mathematical context in the teaching of mathematics. It was sponsored by the Gibraltar Institute, a Jamaica-based nongovernmental organization led by Trevor Campbell (Pomona College) and Reginald Nugent (Cal State Pomona), Jamaica’s College of Agriculture, Science and Education, and Harvey Mudd College.

How We Think About And Prepare To Teach Physics, Dewey I. Dykstra

Physics Faculty Publications and Presentations

We have been preparing physics teachers in the same manner for many decades. Yet, physics education research reveals for some observers disturbing evidence of little or no change in understanding the phenomena occurs as a direct result of physics instruction from elementary school through the college years. The apparent compatibility between these learning results and prevailing paradigm enables the construction of a description the paradigm. If it can be demonstrated that there is even just one alternative paradigm from which powerful alternative pedagogical practice is derived, are we not obligated to change how we prepare to teach physics?

An Interactive Learning Environment For A Dynamic Educational Digital Library, Ee Peng Lim, Dion Hoe-Lian Goh, Yin-Leng Theng, Eng-Kai Suen

Research Collection School Of Computing and Information Systems

GeogDL is a digital library of geography examination resources designed to assist students in preparing for a national geography examination in Singapore. We describe an interactive learning environment built into GeogDL that consists of four major components. The practice and review module allows students to attempt individual examination questions, the mock exam provides a simulation of the actual geography examination, the trends analysis tool provides an overview of the types of questions asked in previous examinations, while the contributions module allows students and teachers to create and share knowledge within the digital library.

Move To Component Based Architectures: Introducing Microsoft's .Net Platform Into The College Classroom, Meg C. Murray

Faculty Articles

A transformation has been occurring in the architectural model for computer-based application intense software systems. This new model, software-as-a-service, will have a profound impact on the design and development of software for many years to come and as such college level computing curriculums will need to incorporate the concepts and methodologies associated with this new architecture. The platform is built upon a view of interrelated, distributed peer-level software modules and components that work in tandem to achieve specified functional goals. From Microsoft's viewpoint, migration to the new platform requires a radical shift in the software development lifecycle. It is becoming …

As the World Wide Web evolves into an immense information network, it is tempting to build new digital library services and expand existing digital library services to make use of web content. In this paper, we present the design and implementation of G-Portal, a web portal that aims to provide digital library services over geospatial and georeferenced content found on the World Wide Web. G-Portal adopts a map-based user interface to visualize and manipulate the distributed geospatial and georeferenced content. Annotation capabilities are supported, allowing users to contribute geospatial and georeferenced objects as well as their associated metadata. The other …

Examining The Reflective Outcomes Of Asynchronous Computer-Mediated Communication On Inservice Teacher Development, Mark Hawkes, Alexander Romiszowski

Instructional Design, Development and Evaluation - All Scholarship

This study explored the professional development experiences of 28 practicing teachers in 10 Chicago suburban schools involved in a two-year technology supported Problem-Based Learning curriculum development effort. Asynchronous computer-mediated communications (CMC) were featured as teacher communication tools of the project. The computer-mediated discourse produced by the teachers was compared with the discourse produced by teachers in face-to-face meetings. Research methods including discourse analysis and archival data analysis were applied to determine the nature of the teacher discourse and its reflective content. The results show that while the computer-mediated teacher dialogue was less interactive, it was significantly more reflective (t=4.14, p=.001) …

Metastable States In Classical And Quantum Systems, Mark Makela, Samantha Parmley, Roger Yu

All Faculty Scholarship for the College of the Sciences

The classical vibrational metastable states in a one-dimensional two-mass system are investigated experimentally and theoretically via the transmission of a coherent wave packet propagating through the system. The Fourier transform of the vibrational signal recorded in between the masses reveals resonant excitations by the coherent wave packet. The time-resolved spectrum indicates that the lifetime of a metastable state of higher frequency is longer than that of lower frequency, which is in contrast with the quantum mechanical double-barrier system. This study, which is easily accessible to physics majors, also demonstrates quantum resonant tunneling in a very simple classical way.

Teaching Parallel Computing To Freshmen, Donald Johnson, David Kotz, Fillia Makedon

Dartmouth Scholarship

Parallelism is the future of computing and computer science and should therefore be at the heart of the CS curriculum. Instead of continuing along the evolutionary path by introducing parallel computation “top down” (first in special junior-senior level courses), we are taking a radical approach and introducing parallelism at the earliest possible stages of instruction. Specifically, we are developing a completely new freshman-level course on data structures that integrates parallel computation naturally, and retains the emphasis on laboratory instruction. This will help to steer our curriculum as expeditiously as possible toward parallel computing.

Our approach is novel in three distinct …

Implementing Educational Software And Evaluating Its Academic Effectiveness: Part Ii, Karen Jolicoeur, Dale E. Berger

CGU Faculty Publications and Research

In Part I, published last month, we presented a successful classroom implementation plan for integrating educational software into elementary school classrooms. Implementing educational software successfully into classrooms is an essential prerequisite to achieving the second goal of the present research-evaluating how much students learned by using specific software programs. In Part II, we will measure how effective eight software programs were at teaching fifth grade students new fraction concepts and spelling words. In addition, we will examine the validity of teacher and student software ratings based on the effectiveness of each program.

Implementing Educational Software And Evaluating Its Academic Effectiveness: Part I, Karen Jolicoeur, Dale E. Berger

CGU Faculty Publications and Research

Two major obstacles are responsible for the delay in getting good educational software into schools. First, software implementation is a complex process that many schools are simply not prepared to undertake. Second, there is very little empirical research available on the specific factors that make educational software effective, leaving it extremely difficult to separate good from poor quality software. We will describe a basic plan for implementing educational software into classrooms, incorporating a research design that permits educational researchers to measure the effectiveness of the software. Part I of this series of two articles presents a basic plan for implementing …

Do We Really Know What Makes Educational Software Effective? A Call For Empirical Research On Effectiveness, Karen Jolicoeur, Dale E. Berger

CGU Faculty Publications and Research

Empirical information on specific factors that make educational software effective in reaching instructional objectives would be of considerable value. The authors describe the current state of evaluation research with educational software and discuss how popular software review methods fall short of meeting our need to know how well specific programs work.
