{"product_id":"books-the-science-of-evaluation-by-ray-pawson","title":"The Science of Evaluation","description":"Evaluation researchers are tasked with providing the evidence to guide programme building and to assess its outcomes. As such, they labour under the highest expectations - bringing independence and objectivity to policy making. They face huge challenges, given the complexity of modern interventions and the politicised backdrop to all of their investigations. They have responded with a huge portfolio of research techniques and, through their professional associations, have set up schemes to establish standards for evaluative inquiry and to accredit evaluation practitioners. A big question remains. Has this monumental effort produced a progressive, cumulative and authoritative body of knowledge that we might think of as evaluation science? This is the question addressed by Ray Pawson in this sequel to Realistic Evaluation and Evidence-based Policy. In answer, he provides a detailed blueprint for an evaluation science based on realist principles.","brand":"World of Books ","offers":[{"title":"Default Title","offer_id":53675074453777,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9781446252437.jpg?v=1781537921","url":"https:\/\/www.worldofbooks.com\/en-gb\/products\/books-the-science-of-evaluation-by-ray-pawson","provider":"World of Books ","version":"1.0","type":"link"}
