Cronbach's Alpha Reliability Test
The Cronbach's Alpha Reliability Test measures the internal consistency or the internal consistency reliability of a questionnaire through the calculation of Cronbach's alpha (α)coefficient.
Cronbach's alpha will generally increase when the correlations between the items increase.
α can take values between negative infinity and 1. As a rule of thumb, Cronbach’s α coefficient of 0.7 or higher (obtained on a substantial scale) indicates a high level of reliability of the ‘translated’ questionnaire.

Session 4: Assessing the Learning Environment II
The school learning environment can be broadly categorised by school, teacher and student dimensions. By these dimensions, we mean --
School: Leadership, school vision and strategic thrusts, school culture, discipline, security and other physical aspects of the environment.
Teachers: Teaching methodology, nurture, beliefs and the ability to bring out the best in every child.
Students: Interactions and relationships with teachers and fellow schoolmates, learning style, attitude and socioemotional learning.
Quantitative measurement of the school learning environment can be measured using the SLEQ (School Level Environment Questionnaire). The dimensions of the questionnaire follow Moo's schema of Relationship, Personal Development and System Maintenance and Change. These dimensions include: Student support, affiliation (in terms of bonding and identity), professional interest, achievement orientation, staff freedom (in terms of personal growth), involvement in participatory decision making, innovation, resource adequacy and work pressure. The questions follow a cyclical format for each dimension (eg. student support follows questions 1, 10, 19, 28) in a scale of 4 to 6 questions. This is to minimise inaccurate answering on the part of survey participants. The responses are graded on a 4-point Likert Scale.
The groups then came together to discuss 3 different case studies of secondary schools in Singapore. The case studies were very authentic and gave perspectives of different learning environments in each school.
Later in the day, we learnt about the use of SPSS software to analyse results obtained from the WIHIC questionnaire by doing the Cronbach alpha reliability test. After compiling the raw data on Excel, we copied the numerical data onto SPSS, leaving out the headings. Edit the headings in the variables view.
Sequence:
1) Click on Analyse
2) Go to Scale
3) Choose Reliability Analysis
4) To calculate value for student cohesiveness, highlight Pref1Sc--7Sc and move them over to the right column
5) Choose statistics
6) Choose Item, Scale......leaving Tukey's test and Intraclass coefficient unchecked.
7) Generate results.
8) Save results (filename.spo)
9) Change the filename to .html or .ppt format so that the file can be viewed without using the SPSS software.
In the analysis of the results, refer to Reliability Statistics, Summary Item Statistics and Scale Statistics.

Reflection for Session 3: What Have I Learnt Today?
Today's takeaway was on the Assessment of Learning Environments -- rationale and approaches in terms of choosing the appropriate instrumentation tool. We were first introduced to the development of major philosophies behind the psychosocial aspect of learning such as motivation, needs, etc beginning with Murray and Lewin's research from the 1930s which transcended to Moo, Walberg, Fisher and Fraser. We also viewed some short video clips comparing lesson delivery styles - didactic, kinesthetic, problem-based and socratic, and how each of them can be effective in meeting the needs of the learners.
There are a wide range of quantitative instrumentation tools that can be used to assess Learning Environments. The rationale for assessing Learning Environments is to ensure that there is a reciprocity on the part of the learner on the teacher's intention so that effective teaching and learning can take place. In the event that reciprocity is not evident, then perhaps the instructor needs to reflect and improve on the classroom processes and the learning environment in general.
As a Science teacher, the instrument that I am particularly interested in will be the Science Laboratory Learning Environment Inventory (SLEI) as it complements Science Practical Assessments. Evidently, as we aspire towards TLLN, teaching and learning in the classroom will be continually evolving towards student-centred learning and constructivist approaches to teaching and learning.
My classmates have surfaced many interesting learning theories in the various researchers' works in the course of their presentations. Will have to go home and read up again. :)

Session 3: Assessing the Learning Environment I
The lesson started off with a recap of what constitutes Learning Environments, the why and what to assessing LE.
We were introduced to the background of prior research in LE, and were exposed to the works of Murray, Lewin, Leary (from the 1930s), Walberg, Moos (from the 1950s) and Fraser, Fisher (from the 1960s to 70s).
Using the Copernic software that was downloaded from http://www.copernic.com/, we were able to conduct a comprehensive search on Murray on the internet.
Background Studies on Murray
Henry A. Murray (1893 - 1988) was an American psychologist. He was one of the most important pioneers who introduced psychoanalysis into American academic psychology.
Drawing influences from Sigmund Freud and Carl Jung, he was most noted for developing the "Need-Press" personality theory and developing the Thematic Apperception Test (TAT) with the help of Christiana Morgan. His TAT test was a means of drawing forth from people by means of words and stories important aspects of personality that an individual could or would not volunteer. The TAT test was designed to be both a diagnostic tool and a research tool, and has contemporary applications even to-date.
His most famous single book, which was the outcome of collaborating with others at his Psychological Clinic, was Explorations in Personality (1938). He also co-edited, with the Harvard anthropologist Clyde Kluckhohn, an influential book of readings, Personality in Nature, Culture, and Society (1948).
Murray's identification of core psychological needs (Murray's Psychogenic Needs), including Achievement, Affiliation and Power (1938) provided the theoretical basis for the later research of David McClelland and underpins development of competency-based models of management effectiveness (Richard Boyatzis), Maslow's Hiearchy of Needs, and ideas relating to Positive Psychology.
*Note:
Psychogenic: originating in the mind or in mental or emotional conflict (according to the online Merriam-Webster dictionary at http://www.m-w.com)
