This second edition elaborates on the application of additional measurement scales and of content analysis. It contains more practical examples of the application of scientific criteria and it includes additional marginal notes that facilitate the comprehension of key concepts. The book also features learning aids, such as executive summaries, self-evaluation and portfolio tasks, plus criteria that students, lecturers and examiners can use to assess the achievement of learning outcomes and evidence of performance. The book ends with a very useful framework of criteria and guidelines to be used when planning, writing, analysing and evaluating research reports.
