Moreover, many faculty members often struggle with knowing \u201chow much\u201d of a particular subject they should teach to their students and at what level. This small-scale, exploratory study seeks to uncover the existence of \u201cthreshold concepts\u201d within Web development. Threshold concepts are the fundamental concepts which, once mastered, allow a learner to progress to a deeper understanding of a subject. An online questionnaire was sent out to 24 instructors within UK higher education institutions who teach Web development subjects. Nine participants responded to the questionnaire and interviews were conducted with five to discuss and expand on the responses provided, resulting in the identification of four areas that were perceived as difficult for students to grasp when learning Web development. Analysis of these areas suggests that threshold concepts do exist within the subject and we offer up two candidates for the field of Web development:\n            <jats:italic>basic programming principles and decomposition and abstraction<\/jats:italic>\n            . Designing a curriculum based on threshold concepts and less on the latest methods, tools, and techniques can go a long way in helping students to become experts in their chosen discipline.\n          <\/jats:p>","DOI":"10.1145\/2700513","type":"journal-article","created":{"date-parts":[[2015,3,9]],"date-time":"2015-03-09T19:03:01Z","timestamp":1425927781000},"page":"1-18","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":12,"title":["Uncovering \u201cThreshold Concepts\u201d in Web Development: An Instructor Perspective"],"prefix":"10.1145","volume":"15","author":[{"given":"Peter","family":"Alston","sequence":"first","affiliation":[{"name":"University of Liverpool, UK"}]},{"given":"David","family":"Walsh","sequence":"additional","affiliation":[{"name":"Edge Hill University, UK"}]},{"given":"Gary","family":"Westhead","sequence":"additional","affiliation":[{"name":"Edge Hill University, UK"}]}],"member":"320","published-online":{"date-parts":[[2015,3,4]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"crossref","first-page":"36","DOI":"10.1177\/1474022212460743","article-title":"Understanding arts and humanities students: Experiences of assessment and feedback","volume":"1","author":"Adams Joelle","year":"2013","unstructured":"Joelle Adams and Nicole McNab . 2013 .
