Here are some approaches to finding books and articles on your topic: psychological aspects and behavioral issues of deaf children in educational settings. First, you can try a search for books and ebooks using the search box on the SCC Library home page. Here are links to results of two searches that I did for books and ebooks using the keywords "deaf children psychology" and "deaf children education." Relevant books will provide you with background information on the topic, and you can access our ebooks immediately. For example, the ebook Processes in Deaf Children with Complex Needs : An Evidence-based Practical Guide looks relevant to your topic.
Next, here are some tips on finding articles. Using OneSearch from the Library main page, I searched with the keywords "deaf children psychology behavior" and I see some promising results, including this scholarly article called "Challenging behaviour in deaf children." When searching the Library databases, it is good strategy to (1) experiment with different keywords, using different combinations of keywords, (2) narrow down your results with the limiters on the left-hand side of the results page, adjusting for date, subject, source type, and others appropriate to your needs, and (3) "drill down" further by looking at the Library's list of research databases, and search within a specific database - this can help you find more relevant results faster, because individual databases cover different disciplines.
In this final example, I searched ERIC, a database that covers educational research. My keywords were "deaf children in school" and the search results will show some articles that may help you delve further into the topic of deaf children in educational settings. I encourage you try the above strategies while experimenting with different keywords and use the filtering / limiting options to find ebook chapters and articles - and once you find something promising, spend a bit of time with it to analyze whether it meets your needs and whether you want to spend more time reading it. Also, feel free to stop by the Research Help Desk at the SCC Library for in-person, one-on-one help with a Librarian during open hours. Hope this helps!
