The <span style=\"text-decoration: underline\">significance<\/span> of a literature review lies in its role as a basis for innovation; it highlights current knowledge, identifies technological gaps, and informs design considerations for new projects. Its <span style=\"text-decoration: underline\">purpose<\/span> is to contextualize engineering challenges within the broader field, justify the necessity of further development, and refine research objectives by outlining the limitations and opportunities in existing engineering solutions.<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h1 class=\"wp-block-heading\" style=\"font-size:22px\">Learning Outcomes<\/h1>\n\n\n\n<ul style=\"font-size:22px\" class=\"wp-block-list\">\n<li style=\"font-size:22px\"><strong>Explain the purpose and significance<\/strong> of a literature review in the context of engineering research.<\/li>\n\n\n\n<li style=\"font-size:22px\"><strong>Identify the key elements <\/strong>of a literature review, including the purpose, historical development, key contributors, and existing knowledge gaps.<\/li>\n\n\n\n<li style=\"font-size:22px\"><strong>Develop a systematic approach<\/strong> to conducting a literature review.<\/li>\n\n\n\n<li style=\"font-size:22px\"><strong>Analyze and synthesize information<\/strong> from key and fringe papers to address contradictions, correlations, and gaps in the literature<\/li>\n<\/ul>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what-is-a-literature-review\" style=\"font-size:52px\">What is a Literature Review?<\/h2>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<p style=\"font-size:22px\">The goal of a <strong>literature review<\/strong> is to provide an overview of existing research or knowledge on a specific topic.
