{"product_id":"9781446252420","title":"The Science of Evaluation: A Realist Manifesto","description":"\u003cp\u003eEvaluation 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 \u003ci\u003eRealistic Evaluation\u003c\/i\u003e and \u003ci\u003eEvidence-based Policy\u003c\/i\u003e. In answer, he provides a detailed blueprint for an evaluation science based on realist principles.\u003c\/p\u003e","brand":"SAGE Publications","offers":[{"title":"Default Title","offer_id":47015190954224,"sku":"9781446252420","price":130.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781446252420_p0.jpg?v=1763817551","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781446252420","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
