Star Library: Which Paper Towel is More Absorbent?
This group activity focuses on conducting an experiment to determine which of two brands of paper towels are more absorbent by measuring the amount of water absorbed. A two-sample t-test can be used to analyze the data, or simple graphics and descriptive statistics can be used as an exploratory analysis. Students are asked to think about design issues, and to write a short report stating their results and conclusions, along with an evaluation of the experimental design.
Data Analysis
The applet in this section allows for simple data analysis of univariate data. Users can either generate normal or uniform data for k samples or copy and paste data from another source to a text box. A univariate analysis is performed for all k samples.
Star Library: What is the Shelf Life?
The Food and Drug Administration requires pharmaceutical companies to establish a shelf life for all new drug products through a stability analysis. This is done to ensure the quality of the drug taken by an individual is within established levels. The purpose of this out-of-class project or in-class example is to determine the shelf life of a new drug. This is done through using simple linear regression models and correctly interpreting confidence and prediction intervals. An Excel spreadsheet

Philosopher and political commentator Daniel Herwitz launched the Gordon Institute for Performing and Creative Arts GIPCA 2010 Great Texts Big Questions lecture series on 4 March when he discussed Talk Show Democracy Stars Celebrities and American PoliticsProfessor Herwitz Director of the Institute for the Humanities at the University of Michigan USA is currently Mellon Visiting Research Fellow at UCT He is the author of Star as Icon about the creation of this media persona from the joint forces
In the experiment described in this paper we investigated the effects of different kinds of computer-based visualizations on the acquisition of problem-solving skills in the domain of probability theory. Learners received either purely text-based worked examples, text plus an instruction to mentally imagine the examples contents, or they could retrieve either static pictures or concrete animations that depicted the problem statement and the problem states achieved by applying a specific solut
Comparing multiple examples within problem categories is usually considered a necessary prerequisite for schema acquisition. However, there is an evident lack of conclusive empirical evidence supporting this claim. Moreover, there are findings indicating that carefully designed one-example conditions may allow for profitable processes of example comparison as well. In line with this reasoning, we present an experiment - that builds up on a series of studies conducted by Quilici and Mayer (1996)
Cognitive tools, defined here as instruments that support or perform cognitive processes for learners in order to support learning, can bridge the difference between open learning environments, like discovery learning environments and traditional supportive instructional environments. This article discusses a definition of the concept of cognitive tool and its use in learning. Two examples of cognitive tools for discovery environments are presented, and it is made clear how these tools can serve
Often research on online communities could be compared to archaeology [16]: researchers look at patterns in digital traces that members leave to characterise the community they belong to. Relatively easy access to these traces and a growing number of methods and tools to collect and analyse them make such analysis increasingly attractive. However, a researcher is faced with the difficult task of choosing which digital artefacts and which relations between them should be taken into account, and h
The Simulation discipline has to face new challenges such as the incorporation of Collaborative Technologies for professional use as well as for teaching purposes. This integration permits the creation of new kinds of support for collaborative learning processes. In this paper, we explore the potential of this synergy with DomoSim-TPC, a synchronous distributed collaborative environment for the teaching and learning of Domotics. The system supports an active, simulation-based and problem-based a
The goal of this paper is to explore the possibility of using CSCL component-based software under a Grid infrastructure. The merge of these technologies represents an attractive, but probably quite laborious enterprise if we consider not only the benefits but also the barriers that we have to overcome. This work presents an attempt toward this direction by developing a generic platform of CSCL components and discussing the advantages that we could obtain if we adapted it to the Grid. We then pro
Collaborative applications usually register user interaction in the form of semi-structured plain text event log data. Extracting and structuring this data is a prerequisite for later key processes such as the analysis of interactions, assessment of group activity, or the provision of awareness and feedback. Yet, in real situations of online collaborative activity the processing of log data is usually done offline since structuring event log data is, in general, a computationally costly process
This study aims to explore the importance of the efficient representation and management of the event information generated from group activity in online collaborative learning practices so that we can use it to provide awareness about individual and group behaviour. The achievement of this goal first involves the design of a conceptual model of collaborative learning interaction that structures and classifies the information generated in an online collaborative learning situation at several lev
Several intelligent tutoring systems contain modules that support reflection after practice exercises. However, there is very little research on reflective dialogue and its relation to dialogue during problem solving that can guide this effort. The approach to analyzing educational dialogue described in this paper was developed to address this problem. Using statistical and machine learning methods, we compared the frequency and structure of speech acts by avionics students and experts during pr
This paper aims at showing, through a case study, one possible application of Computer Learner Corpus (CLC) to Network Based Language Teaching (NBLT). Research has shown how CLC can be used both for Second Language Acquisiton (SLA) research and Foreign Language Teaching (FLT), especially if they are tagged, that is, if interpretative annotations are added to the corpus (e.g. error annotations). Online learning generally takes place inside virtual environments where learners exchange mainly writt
This research study aims to investigate the usability issues of a computer game; regarding how people learn a new game. Because the user characteristic and the strategies they use while learning a new tool are important factors for usability, they were also taken into account in the study. Both qualitative and quantitative methods were used in the study. 16 participants played the computer game. They were also observed and their eye-movements were recorded by an eye tracking device. Results show
A civil engineering professor at the University of California at Berkeley is working on a novel way of maintaining a building's structural stability after an earthquake or terrorist bomb. The team of researchers working with the professor have designed and tested a system that uses cables for backup support in case main support beams failed. This site is the homepage of the professor leading this research. A number of projects on which he is currently working are described, as well as an ongoing
