This exercise demonstrates the principle of parsimony in constructing cladograms. Although it is designed using mammalian cranial characters, the activity could be adapted for characters from any group of organisms. Students score categorical traits on skulls and record the data in a spreadsheet. Using the Mesquite software package, students…

The purpose of this paper is to examine a specific online pedagogical tool, "Digital Moments" that can be an effective strategy for building online communities in a knowledge building environment. While the paper will examine the specific techniques and teaching methodologies that enabled the authors to create authentic online learning…

In grade 1, Danish students used a talking book with TTS (text-to-speech) and participated in a learning design with emphasis on decoding and reading for meaning in written text. The students all read the same unfamiliar text, which for many of the students would traditionally be considered being at their frustration level. Basing the intervention…

Assessment of groups in CSCL context is a challenging task fraught with many confounding factors collected and measured. Previous documented studies are by and large summative in nature and some process-oriented methods require time-intensive coding of qualitative data. This study attempts to resolve these problems for teachers to assess groups…

The purpose of this study was to explore the variables that affect an individual's intention to use business intelligence technology in organizations.

This paper describes the use of the free software, to teach graphs of logarithmic functions at an Ethiopian College of Teacher Education. Data comprised two video-recorded lessons and interview data provided by a mathematics teacher educator, and three primary school mathematics pre-service teachers who were in the class of learners. Pre-service…

Information retrieval (IR) systems have tremendously broaden users' access to information. However, users need to select their needs from trillions of information indexed daily. Due to the "semantic gap" between queries and indexed terms in IR system, whether users can satisfy their needs depends on whether they use the correct terms as…

Instructors are under pressure to integrate technology into their traditional or online instruction, but often they aren't sure what to do or why they should do it. The "Technology Toolbelt for Teaching" offers instructors a down-to-earth guide to common technologies, explains the pedagogical purposes they serve, and shows how they can be used…

Serious games have a great potential for training and educating people in novel and engaging ways. However, little empirical research has been done on the effectiveness of serious games, and although early findings do point to a moderately positive direction, even less is known about why some games succeed in effectively educating while others do…

This study discusses and presents various strategies employed by novice programmers concerning exception handling. The main contributions of this paper are as follows: we provide an analysis tool to measure the level of assimilation of exception handling mechanism; we present and analyse strategies to handle exceptions; we present and analyse…

IMS Learning Design is a specification to capture the orchestration taking place in a learning scenario. This paper presents an extension called Generic Service Integration. This paradigm allows a bidirectional communication between the course engine in charge of the orchestration and conventional Web 2.0 tools. This communication allows the…

Organizations expend a great deal of time, effort and money on the implementation of enterprise resource planning (ERP) systems. They are considered the price of entry for large organizations to do business. Yet the success rate of ERP systems is poor. IS literature suggests that one possible reason for this is the underutilization of these…

Users assume statistical software packages produce accurate results. In this article, the authors systematically examined Statistical Package for the Social Sciences (SPSS) and Statistical Analysis System (SAS) for 3 analysis of variance (ANOVA) designs, mixed-effects ANOVA, fixed-effects analysis of covariance (ANCOVA), and nested ANOVA. For each…

Purpose: A greenhouse gas (GHG) inventory was conducted for Yale University's procurement of goods and services over a one-year period. The goal of the inventory was to identify the financial expenditures resulting in the greatest "indirect" GHG emissions. This project is part of an ongoing effort to quantify and reduce the university's…
