The Correlation of Binary Acid Strengths with Molecular Properties in First-Year Chemistry  Travis D. Fridgen
This article replaces contradictory explanations for the strengths of different binary acids in first-year chemistry textbooks with a single explanation that uses a BornHaber cycle involving homolyic bond dissociation energies, electron affinities, and ion solvation enthalpies to rationalize trends in the strengths of all binary acids.

Factors That Influence Relative Acid Strength in Water: A Simple Model  Michael J. Moran
The pKa's of diverse aqueous acids HA correlate well with the sum of two gas-phase properties: the HA bond-dissociation enthalpy and the electron affinity of the A radical. It is suggested that rather than bond strength alone or bond polarity, the sum of the enthalpies of these two steps is a fairly good indicator of relative acidity.

The computer as student: An application of artificial intelligence  Birk, James P.
The author describes how the development of computer software to teach about chemical reactivity also provides information about how we should teach several topics in general chemistry.

A procedure for determining formulas for the simple p-block oxoacids  Kildahl, Nicholas K.
Formulae for p-block oxoacids baffle high school and undergraduate students. This paper presents a procedure for developing these formulas based on the concept of total coordination number of the central atom in the molecule or ion.
