Very good read on Exploratory Factor Analysis
am battling “zombies” these days and comes the time that i need to use factor analysis for analysis. however, there are so many questions for a newbie like me, came across a few readings but nothing as useful as this which Dr Chai CS has shared:
Costello, Anna B. & Jason Osborne (2005). Best practices in exploratory factor analysis: four recommendations for getting the most from your analysis. Practical Assessment Research & Evaluation, 10(7). Available online: http://pareonline.net/getvn.asp?v=10&n=7
if you are exploring the use of factor analysis and you have qns like which extraction methods to choose, no. of factors to retain, sample size etc, just grab this article and you’ll be on the way to a good start. Thank you 蔡老师 (:
ideas from Classroom News Feb 09
juz “fetched” my copy of feb 09 classroom news from the server.
some useful ideas within:
1. on cyber-wellness/safety: a study that involved emailing students who posted explicit contents to their socialnetworking profile (myspace, facebook as such). awareness through email brought about behavioural change to some students. this idea could be tested n come in handy for a teacher 🙂
2. students turned to video clips in youtube/teachertube/schooltube for learning. students can “watch the video as many times as … needed”; thinking out loud processes can be recorded and shared as well, and it may be ‘not as daunting’.
3. reports and discussed a survey that suggested “sending or posting nude or semi-nude cell phone pictures starts at a young age and becomes even more frequent as teens become young adults” … this would fall in the same category as (1) as well. some food for thoughts, including “Most parents have at least some sort of experience or
understanding of what adolescence was like in terms of other risky behaviors, but no one old enough to have teenage children today had a cell phone when they were
teens”
