• Introduction
• In the period from March to June 2003, a distant
  course on the usage of computers in physics
  laboratory was held by the Department of Physics
  Education.
• Duration of the course 12 weeks
• Topic Coach 5 experiments and data processing,
  computer modelling and data video measurements
• Participants a small group of voluntary
  secondary-school teachers from various regions of
  Slovakia. Some of them already had prior
  experience with Coach before the course started.
• Tools for the distance communication - commonly
  available at any university or, without any
  special costs for performing the course.
• Follow up - continuation with the same group,
• - a new group of in-service
  teachers
• Support of national projects
• Aim
• To develop methods and find tools for distance
  instructing of computer-based measurements,
  dynamical computer modelling and video clip
  analysis

3

• Objectives
• Participants after taking active part in DE
  should be able to
• communicate by e-mail and a videoconferencing
  system with the training centre
• carry out computer-based measurements with
  interface and selected sensors
• be familiar with the basics of dynamical
  modelling
• analyse video clips depicting real-life physical
  situations and perform video measurements on them
• use spreadsheets for data processing
• use graphs for communication of physical
  information together with graphical analytical
  tools such as derivative, integral
• build their own new activities, make up physical
  tasks by means of Coach 5 software
• create electronic presentations with images and
  video clips inserted directly in slides
• publish their experience at a web site,
  participate in building web database of physical
  experiments
• implement new methods into physics education

• Structure of the distance course in computer
  assisted secondary physics education
• initial presence meeting
• lending of the necessary Coach hardware
• basic instruction in hardware and software usage
• fundamentals of electronic communication
• several distance lessons
• measurement and data processing 5
• dynamical modelling 3
• data video measurements - 2
• mainly carried out asynchronously but were
  supplemented with synchronous meetings on demand
  for consultation at the agreed time and date
• evaluation of the course in an on-line survey
• presence final meeting
• presentation of a measurement, model or a video
  measurement made on their own
• discussion of their experience with Coach usage
  at schools
• bringing back of the experimental set.

Communication tools All the selected tools were
computer-based technologies.

Types of resources and methods of their
deliveriveng Texts and assignments organised by

• Supporting materials
• Two CD-ROMs Chapters on Didactics of Physics
  and Experiments and Models in computer-based
  laboratory
• Activities (Coach files offered to students with
  detailed procedure instructions)
• Web materials (to be gradually produced)

• NetMeeting
• NetMeeting provides powerful conferencing and
  collaboration functions in a complete, integrated
  package for the Internet or intranet.
• Possibilities and Advantages
• Cost effective free software to download or
  already included in Windows package
• Point-to-point audio and video conferencing
• Multipoint data conferencing using tools
• Whiteboard
• Chat (and Whisper- secret message)
• File transfer (sending assignments,results)
• Program sharing (of a single program)
• Remote desktop sharing
• Disadvantages and Deficiencies
• Group audio/video conferences are not possible
• Windows application only
• Technical equipment required for audio/video
  digital conferencing sound card, microphone,
  speakers, video camera (video capture card)

• Moodle
• Moodle is a software package for producing
  internet-based courses and web sites.
• Possibilities and Advantages
• Free as Open Source software
• More than 28 language versions every user can
  choose the language for Moodle interface.
• Students create their own login accounts. Email
  addresses are verified by confirmation.
• Course formats - week or topic lessons or
  discussion-focussed social format
• Course activities of the following type -
  Forums, Journals, Quizzes, Resources, Choices,
  Surveys, Assignments, Web links
• Teachers opportunity of tracking activity of
  each student on one page
• System of deadlines of assignments
• Grading with exporting into text and/or excel
  files
• Teacher-student feedback, e-mail notification of
  it
• Building of a database of questions,
  multiple-choice questions with either single or
  multiple answer
• Attachment of a file (up to 2MB)
• Voluntary or compulsory subscription to
  discussion forums

• Moodle
• Disadvantages and Deficiencies
• Administration of courses is a bit clumsy, no
  finished courses are stated and a course contents
  could be more transparent
• Compatibleness with standard electronic courses
  is not granted
• Accessibility of discussion contribution to
  every participant, it cannot be chosen by a
  student to whom to address a topic or a reply
• No Help in navigation for course participants
• Grades are not stated in percents of the total
  course credits
• When compared to News board, planning calendar
  for personal and public events is missing
• The possibility of open survey is missing (only
  some standard surveys with set of prepared
  questions are at ones disposal)
• The environment is still under construction
• Weak studentstudent interaction (they are not
  motivated by results of the others)
• No platform for ideas sharing with attached
  documentation

• VNC viewer (Virtual Network Computing)
• A remote display system which enables to view a
  computing 'desktop' environment from anywhere on
  the Internet
• Possibilities and Advantages
• It is small and simple, no installation needed
• Platform-independent ( e.g. Windows, Linux)
• Sharable from multiple points by several persons
  to view, use and control.
• Free to use (under GNU General Public License).
• Disadvantages and Deficiencies
• Caution total computer sharing of multiple
  users, not only program sharing.

• VRVS
• VRVS is a web oriented system for
  videoconferencing and collaborative work over IP
  networks.
• Possibilities and Advantages
• Various conferencing rooms, which are booked in
  advance
• Integrated system combining various
  communication tools chat, audio and video
  conferencing, desktop sharing (VNC)
• Can be used with various platforms (e.g.
  Windows, Linux, Mac, Solaris)
• Video conferences are accesible from multiple
  points connected to a global net of reflectors.
• Many ways to share documentation During Room
  reservation, one can attach URL links of the
  documentation. During the meeting, there wiil be
  a list of icons pointing out the documents.
  Possibility of synchronized web browsing in
  chat window.
• Disadvantages and Deficiencies
• System requires net connection fast enough so
  that all its tools can function well
