Comments on Assignment #1 35
Some Observations ö silly mistakes, e. g. , öa nameless answer script ö a table cut into two pieces on two pages ö more important mistakes ö ö not answering the question grammatical errors 36
The Question ö “In this assignment, you first browse the web for statistics related to container terminals. Then put down your assertions (observations, points, claims, conjectures, etc. ) in about 300 words. Use the statistics collected to substantiate your assertions. ” 37
The Question ö the question asks for ö (1) statistics related to container terminals ö (2) your assertions ( ) from statistics ö (3) justifications of assertions by statistics observations, points, claims, conjectures, etc. ö more than simpler supplying statistics 38
Some Observations ö the most important mistakes: directly copying sentences from web ö plagiarism, one of the biggest mistakes in school ö loss of opportunity of self improvement ö at the end of the day, your abilities and skills that matter, not your degree 39
To Avoid Plagiarism drop down statistics but not phrases, certainly not sentences ö summarize ideas and points in your own words ö reorganize material in the way suitable for the purpose, not the structure of your source ö 40
My Grading Principle ö looking for ideas, organization, presentation, grammar Self-Expressing Strong ideas and organization Strong Weak 41 Weak
