A Nopreprint on the Pragmatic Logic of Fractions

Authors: Jan A Bergstra
Comments: 17 Pages.

A survey of issues concerning the pragmatic logic of fractions is presented, including a seemingly paradoxical calculation. The presence of nested ambiguity in the language of fractions is documented. Careful design of fraction related datatypes and of logics appropriate for such datatypes is proposed as a path towards novel resolution of these complications. The abstract datatype of splitting fractions is informally described. A rationale of its design is provided. A multi-threaded research plan on fractions is outlined.

Predicting a Student’s College Class Rank

Authors: Robert M. Hartranft
Comments: 2 Pages.

This paper describes a quantitative, verifiable method for predicting the college freshman year class rank at any American college of a student at any American secondary school. Using only existing data pools, the basic method also provides useful graphical summaries for individual secondary students and for entire secondary schools. If further given actual freshman rank data from simple student surveys and/or from visiting college representatives, the method appropriately refines and validates the predictions and the summaries. Given summary data from another school or group of schools, the method allows immediate and meaningful comparisons to the other school or group.

Why Should Governments Fund and Run the Usl Pilot Studies This Spring (Draft1)

Authors: Dongchan Lee
Comments: 5 Pages.

The USL pilot study series were created to dispel the doubts of its too-good-to-be-true claims. The previous off-line USL pilot study results imply that it is possible to boost the math skill average of a region (city, state, or even a country) by 1 year within a few weeks. If done simultaneously online, this can happen within a few days, which most people have been in total disbelief in spite of all the evidences and video testimonials and support videos of over 700 students, teachers and principals. This paper is to propose to various city, state, or national governments to participate in a series of scaled-down version of the previous USL pilot studies. We propose the USL 1.0, 0.5, and 0.25 each of which corresponds to quickly boost the regional math – proportionally speaking as the sample sizes will be limited - by 2 years (for the national governments only), 1 year (for the national or state governments) or ½ year (for the state or city governments) respectively. At the end, we propose to create Boards of Social Enterprises together where the USL team and the participating governments share the growths of the future Social Enterprises if the governments choose to do so as the implications out of even USL 0.25 (boosting the average math skill levels by half a year) or USL 0.5 (boosting the average math skill levels by half a year) are profound because it takes usually a few decades to improve the average math skill levels of a nation by 1/2 year in the history of OECD countries and rarely they boosted 1 year of math skills.
