The purpose of the study was to investigate the relationship between critical thinking abilities and critical thinking dispositions of preservice teachers in Taiwan. Critical Thinking Scale and Critical Thinking Disposition Scale were administrated to preservice teachers in Taiwan. A total of 1094 valid samples were obtained for investigating preservice teachers¡¦ critical thinking abilities, and 853 valid samples were obtained for investigating preservice teachers¡¦ critical thinking dispositions and the relationship between critical thinking abilities and critical thinking dispositions. The data were analyzed by descriptive statistics, independent sample t-test, one-way ANOVA, one-way MANOVA, and canonical correlation. The results showed: (1) the scores of preservice teachers¡¦ critical thinking abilities and critical thinking dispositions were quite high; (2) female preservice teachers¡¦critical thinking abilities were significantly higher than male preservice teachers¡¦; (3) significant differences of critical thinking abilities across age levels were only found in Interpretation Subscale; (4) there were no significant differences of critical thinking abilities in education levels; (5) critical thinking abilities of preservice teachers at technological and vocational universities were significantly lower than general universities and universities of education; (6)critical thinking abilities of preservice teachers from college of social sciences were significantly lower than those from college of liberal arts and college of science; (7) there were significant differences of critical thinking abilities between those who took philosophical courses and those who did not take philosophical courses; (8) there was no significant relation between preservice teachers¡¦ critical thinking abilities and critical thinking dispositions; (9) preservice teachers¡¦ background, relevant curriculum experiences, and critical thinking dispositions accounted for 13% of critical thinking abilities through two canonical factors.

The intent of this explanatory sequential mixed-method study is to examine Islamic teachers thoughts on improving critical thinking skills in elementary schools in the Southwestern province of Saudi Arabia. This study involves the collection of quantitative data and an explanation of the quantitative results with qualitative data. In the first phase, a survey is administered to Islamic teachers in Saudi elementary schools to assess their opinions on improving students' critical thinking skills and to investigate the factors that influence or hinder their implementation of critical thinking instruction. In the second phase, qualitative data is collected using semi-structured interviews with a number of Islamic teachers in order to explore more fully their perceptions toward improving students' critical thinking skills in Saudi elementary schools. The reason for collecting both quantitative and qualitative data is to obtain a better understanding of the gathered information than would be possible using only one of these methods. In regard to the barriers for improving the critical thinking ability in elementary education students, the study participants reported seven major obstacles, which are student ability, teaching methods, classroom structure, Saudi society and the school community, pre-service teachers preparation programs and in-service teacher professional developmental programs, and the Islamic studies curriculum. The highest ranked obstacle was student ability, with an overall mean of 4.31. Teaching methods, with a total mean of 4.29, was the second most cited barrier. The third was classroom structure, with a total mean of 3.72. The study participants ranked society and school community as the fourth obstacle, with a total mean of 3.70, and pre-service teachers preparation programs and in-service teacher professional developmental programs with a total mean of 2.69. The Islamic studies curriculum was ranked sixth in obstacles to improving critical thinking for elementary education students, with a total mean of 2.57. These findings suggests there is a need to examine female Islamic teachers' perceptions toward critical thinking in the Southwestern region of Saudi Arabia in order to identify the similarities and differences between the perceptions of male and female teachers. It is vital to investigate perceptions of teacher of other disciplines, such as language art, social science, English, and math, in an effort to provide policy makers in the Ministry of Education with a holistic picture of the Saudi educational system. Qualitative studies, interviews with students, and classroom observation can be carried out to investigate students' perceptions as to how critical thinking is taught in the classroom and whether teaching style is a primary obstacle to it being taught. There is an urgent need to examine in depth the influence society and the school community has on teaching students' thinking in general and critical thinking in particular. Finally, more research is needed on the pre-service education programs and in-service professional training programs in terms of building teaching programs on critical thinking skills.

In 1997, NLNAC added critical thinking as a required outcome for accreditation of associate degree nursing (ADN) programs. Until recently general critical thinking tests were the only available standardized critical thinking assessment tools. The emphasis has shifted to discipline specific tools. This concurrent validity study explored the correlation between two critical thinking tests, a general skills test, the California Critical Thinking Skills Test (CCTST) and a discipline specific test, the Arnett Critical Thinking Outcome Evaluation (CTOE). Both tests are based on the same definition of critical thinking. The CCTST, developed in 1990, covers discipline neutral content in multiple choice items. The CTOE, a free entry, written response test developed in 1998, assesses critical thinking in nursing situations using a partial credit model. A convenience sample of 434 sophomore ADN students from 9 programs in Texas completed the demographic survey and critical thinking tests in 1999. The sample was 87.9% female and 74.2% Caucasian, with a mean age of 31, mean GPA of 3.13, mean 3.7 years healthcare employment experience, mean CCTST score of 15.0023 and mean CTOE of 82.69. The sample also included 22.4% current LVNs, 15.7% with prior degrees and 53.5% in the first generation of their family to go to college. With Pearson correlation, three of four hypotheses concerning correlation between CCTST and CTOE scores were accepted, showing weak but significant correlation. GPA positively correlated but healthcare employment experience, first generation and minority status negatively correlated with CCTST scores. GPA correlated positively with CTOE scores. Stepwise multiple linear regression with CCTST scores retained GPA, healthcare employment experience, prior degree, and first generation in college status. The significant, positive correlation between CCTST and CTOE scores was weaker than expected. This may be due to the different formats of the tools, or a fundamental difference between a general critical thinking skills test and a discipline specific tool. Critical thinking is highly contextually sensitive and disciplines emphasize skills differently. Both tests may be useful in a critical thinking assessment program since they measure different aspects and contribute to a composite picture of critical thinking. Research should continue on discipline specific tools.
