传统的教学方式试图把知识与行动、理论与实践结合起来,即:首先是教授理论,然后是布置“应用”或“转化”型的作业,但已经有许多实证和理论研究都对其有效性明确提出了质疑.基于相关理论研究并结合实践,认为:要将实践与理论平等地结合起来;要对错误持开放的态度;要通过敏捷性来促进实质性学习.这样既能在理论上也能在实践上培养学习者的创新能力.

Patients with scalp psoriasis suffered from a lower quality of life relating to the highly visible site of their psoriatic lesions. In consequence this fact stimulates investigations involving treatments of this dermatologic disease. The aim of this review is to evaluate the topical treatments for scalp psoriasis compared with placebos. Methods: A systematic review was performed using searches in the database LILACS, MEDLINE, Cochrane Library, and Embase. As selection criteria were chosen eligible publications involving randomized controlled trials, patients with scalp psoriasis diagnosed clinically or by biopsy, interventions with topical treatments for scalp psoriasis compared with placebo. Outcome related to the reduction in severity of psoriasis of the scalp, assessed by physicians and patients, and assessment of adverse effects that required discontinuation of treatment. The results have shown that the patients were aged 12 to 97 years, including 3441 patients. Ten of the fifteen studies included reported gender data. Patients were mostly female. Twelve studies were about psoriasis’s severity. These studies in which the severity has been described, the classification of severity was mild (0 study), mild to moderate (1 study), moderate to severe (11 studies) and severe (0 study). In conclusion, topical corticosteroids, calcipotriol, ciclopirox olamine and associations between them are effective in the treatment of scalp psoriasis. Clobetasol propionate (0.05%) was the most effective active ingredient in several vehicles in the induction treatment of scalp psoriasis.
