Using Portfolios in Higher Education.
One constructivist approach to assessing student learning is the use of portfolios. The contents of a portfolio demonstrate what a student knows and can do. The portfolio indicates actual products and processes a student has developed, as exemplified in the description of the contents of a student portfolio in a teaching methods course. Portfolios may also be used to extend the scope of the curriculum. The portfolio may be the major data course for a grade, but pride of ownership and achievement may motivate the student to learn more. A portfolio can be an important toyin linking course objectives, learning opportunities, and assessment procedures.

Use of reflective portfolios in health sciences education.
Reflective portfolios are a collection of evidence that through critical reflection on its contents demonstrate achievement as well as personal and professional development. The purpose of this paper is to provide a review of the literature on the use of reflective portfolios and to develop a set of factors to guide schools and colleges of pharmacy as they implement reflective portfolios into their respective curricula as stated in Standards 2007.
Testosterone levels, handedness and sex ratio at birth.
Geschwind has hypothesized that levels of androgens in utero affect postnatal laterality preferences, high levels being associated with left-handedness of offspring. I have hypothesized that high parental androgen levels at the time of conception are associated with subsequent male births. However, left-handed parents seem to produce an excess of female, not male, offspring. This finding could be reconciled with the two hypotheses if individuals who were exposed to high levels of androgens in utero had low circulating levels in adulthood. Some evidence for this loophole is reviewed here. Lyster & Lloyd (1987, J. theor. Biol. 126, 125) have reported that (consistent with the hypotheses) index left-handed men have an excess of brothers; but, contrary to the hypotheses, index left-handed women have an excess of sisters. Accordingly these authors proposed that left-handedness in females is associated not with high levels of androgen in utero, but with a "sensitivity" to it. If such sensitivity were associated with low androgen levels, it might explain an excess of sisters among the sibs of left-handed women. It is shown here that evidence in agreement with this hypothesis (though not discriminating between it and Geschwind's) suggests that the sex ratios of offspring of LH male x RH female and of RH male x LH female matings, are both low.
