Introductory chemistry textbooks often present valence bond (VB) theory as useful, but incorrect and inferior to molecular orbital (MO) theory, citing the electronic structure of O2 electron delocalization evidence. Even texts that initially two theories on equal footing use language biases students toward MO approach. However, these “failures” VB are really just misconceptions and/or misapplic...

The research aims to solve the methodological issue of studying weather types in Introductory Geography Course. analysis school textbooks for Course showed that they contain either limited information on or no at all. A survey Year 6 students revealed their difficulty formulating definition concept “weather type”, as well lack differences definitions concepts type” and “weather”. Nevertheless, ...

Although instruction on meiosis is repeated many times during the undergraduate curriculum, many students show poor comprehension even as upper-level biology majors. We propose that the difficulty lies in the complexity of understanding DNA, which we explain through a new model, the DNA triangle The DNA triangle integrates three distinct scales at which one can think about DNA: chromosomal, mol...

A number of introductory textbooks for Haskell use calculations right from the start to give the reader insight into the evaluation of expressions and the behavior of functional programs. In fact, many programming concepts that are considered to be important by the functional programming paradigm, such as recursion, higher-order functions, pattern-matching, and lazy evaluation, can be explained...

The ability to solve probability word problems such as those found in introductory discrete mathematics textbooks, is an important cognitive and intellectual skill. In this paper, we develop a two-step endto-end fully automated approach for solving such questions that is able to automatically provide answers to exercises about probability formulated in natural language. In the first step, a que...

This study provides a meta-analysis of research on the associations between relationship conflict, task conflict, team performance, and team member satisfaction. Consistent with past theorizing, results revealed strong and negative correlations between relationship conflict, team performance, and team member satisfaction. In contrast to what has been suggested in both academic research and intr...

Although the standard hydrogen electrode is never used in practice today, it is the standard against which all other standard electrode potentials are referenced. Surprisingly, even though a drawing of the standard hydrogen electrode appears in most introductory textbooks on analytical chemistry, very few of the electrodes would work in practice. The answer why none of the depicted electrodes (...

In this case study, wiki technology was applied to the development of an introductory academic textbook on information systems. While the development, production and distribution of traditional textbooks are influenced by commercial interests, the wikitextbook was developed collaboratively by faculty and by students, and was made available online free of charge. After about two years of activit...

The most important part of an introductory programming course is to teach the students a systematic approach to the development of computer programs. Revealing the programming process is an important part of this; however, textbooks do not address the issue – probably because the medium is unsuitable for this kind of descriptions. We have found that videos in the form of narrated programming se...

Surgical diagnosis is riot a new idea, but we do not know of any other short and concise book which deals with this subject exclusively and completely. Such a book will therefore find a definite place in students' and practitioners' libraries, provided of course that it is up to standard. We have no hesitation in saying that this book meets this requirement. The chapter headings follow very muc...
