    Dr. Bob Belford has created many pencasts for chemistry to support his Preparatory Chemistry (Chemistry 1300) course at UALR (University of Arkansas at Little Rock).* These pencasts complement lecture outlines and interactive quizzes which Dr. Belford “hopes to move to a dynamic site in the near future”. Altogether the pencasts, outlines, and quizzes make for an extraordinary set of resources for beginning chemistry students.

    Dr. Belford makes an important note about how pencasts sometimes replay: “Please note that the [Livescribe] pen capture software has some flaws and some of the penstrokes are not presented as they were performed. Like when I cancelled out a unit, it is now showing that occuring as I write the unit, not afterwards. You need to follow the logic of the audio file.” I (Tim Fahlberg) have also noticed this in a few of my pencasts and will share this feedback and hope for a fix from the Livescribe software development team.

    Dr. Belford’s pencasts are here: chem1300 and include:

    1.C Pencasts These are experimental pencasts using a livescribe pulse pen. This material is under development and I am not happy with the way they are currently posted. Be sure to turn your speakers on.

    a. Algebra Review:

    Pencast 1.1 PV=nRT, solve for R
    Pencast 1.2 E=hc/lambda, solve for lambda
    Pencast 1.3 Q=mc(TF-TI), solve for TF
    Pencast 1.4 mCcC(TF-TC) = -mHcH(TF-TH), solve for TH
    Pencast 1.5 mCcC(TF-TC) = -mHcH(TF-TH), solve for TF
    Pencast 1.6 E = R[(1/ni2)- (1/nf2)], solve for nf

    b. Arithmetic with Scientific Notation and SI Prefixes:

    Pencast 1.7 Addition and Substraction of numbers in Scientific Notation
    Pencast 1.8 Multiplication and Division of numbers in Scientific Notation
    Pencast 1.9 Converting SI prefixes for numbers in scientific notation

    c. Percent Calculations

    Pencast 1.10 Calculating Mass % from the Mass of Two Species
    Pencast 1.11 Calculating Mass from Mass % and the Mass of Other Species


    d. Calculations Involving Conversion Factors or Temperature Conversions

    Please note that the pencapture software has some flaws and some of the penstrokes are not presented as they were performed. Like when I cancelled out a unit, it is now showing that occuring as I write the unit, not afterwards. You need to follow the logic of the audio file.

    Pencast 1.12 Volume from length measurements
    Pencast 1.13 Mass from Volume and Density
    Pencast 1.14 Fahrenheit from Celsius Measurements
    Pencast 1.15 Celsius from Fahrenheit Measurements

    * From Dr. Belford’s site “This is a temporary site being used to organize class material. It is hoped that this material will be moved to a dynamic site in the near future. This is not an online course …”
