“…Most of the studies reported that over a third or probably half of the students enrolled in calculus course(s) each year failed the courses. Numerous studies had been conducted, focusing on the difficulty in acquiring a good working knowledge of calculus (Dreyfus, 1991;Madison & Hart, 1990;Cipra, 1988;NCTM & MAA, 1987;Orton, 1983a;1983b) and on the influencing factors that contributed to the underachievements in calculus (Tang et al, 2010, Chen et al, 2002Tucker & Leitzel, 1995;Orton, 1979). As many problems exist with regards to calculus, there were many national attempts towards calculus reform (Smith III & Star, 2007;Hurley et al, 1999;Narasimhan, 1993;Ferrini-Mundy & Graham, 1991).…”

This study seeks to examine university students’ attitudes and their perceptions on calculus education. Lecturers’ suggestions to remedy the current situation of calculus learning were also investigated. The instruments of this study consisted of three sets of questionnaires, aimed at collecting data regarding students’ attitudes and perceptions on calculus and lecturers’ suggestions. The respondents consisted of 278 full-time diploma students in a public university in Malaysia. The findings indicate that the students’ attitudes towards the Course of calculus according to gender were insignificant. However, there was a significant difference in the students’ attitudes towards the Field of calculus between female and male students. Students of Pre-Calculus and Calculus I were found to be feeling, thinking, and behaving similarly about calculus. Their attitudes towards the Field of calculus among the four engineering and science programmes were significant. After attempting 39.27% of the given questions, students’ perceptions on the difficulty of the questions remained the same, which was neither easier nor harder than they expected. Nevertheless, students’ perceptions changed positively (questions more difficult than expected) in 19.45% of the questions and negatively (questions easier than expected) in 41.28% of the questions. The implications from these findings provided inputs to improve calculus teaching and learning. Information regarding students’ attitudes toward calculus could help lecturers to design comprehensive calculus lessons that suit all kinds of students. Students also need to change their attitudes towards calculus, for example by having a closer inspection of the exact nature of the calculus questions before attempting them.

Structure/Activity/Property Relationships (SARs, SPRs, and PARs) appears with the studies of Louis Plack HAMMETT in 1937 [1]. The most important applications of Hammett's equation were summarized in [2].Quantitative relationships (QSAR, QSPR, QPAR) occur when the property/activity is quantitative. Not all properties and activities of chemical compounds can be classified as quantitative. In fact, few properties meet all theoretical requirements to be quantitative [3]. From this reason in the last time are avoided to be used QSAR, QSPR, and QPAR, in their place being used (Q)SAR, (Q)SPR, and (Q)PAR, or more simple SAR, SPR, and PAR. Structure-based approaches have two levels (topological and geometrical). In the topological based level, an atom, a bond from a molecule can exist (and then are evidenced through electronic transitions and/or molecular vibrations and/or rotations) or not (being a matter of 0 and 1). Not so simple stays things related to molecular geometry (especially on liquid or gas phases). Heisenberg uncertainly principle [4] shows the uncertainly rules presented at micro level (molecular and atomic level). More than that, molecular geometry depends on the environment where the molecule is (vicinity of the molecule), temperature, pressure, so on, thus dealing with molecular geometry is both a matter of relativity and a matter of uncertainty. Thus, Structure-Property-Activity Relationships (SPARs) must deal with certainties (such as molecular topology), uncertainties (such as molecular geometry), relativities (such as biological activities) and evidences (such as physical and chemical quantitative properties MATERIALS:The hydrophobicity on Hessa et al. scale [ 10 ] of fifteen standard amino acids was the property of interest.The experimental values of hydrophobicity were as follows: alanine (0.11), asparagine (2.05), aspartate (3.49), cysteine (-0.13), glutamine (2.36), glutamate (2.68), glycine (0.74), isoleucine (-0.6), leucine (-0.55), lysine (2.71), methionine (-0.1), phenylalanine (-0.32), serine (0.84), threonine (0.52), and valine (-0.31).
