The effects of environment‐based education on students' critical thinking skills and disposition toward critical thinking

This study examined the relationship between environment‐based education and high school students' critical thinking skills and disposition toward critical thinking. Four hundred four 9^th and 12^th grade students from 11 Florida high schools participated in the study. A Pretest‐Posttest Nonequivalent Comparison Group Design (9^th grade) and a Posttest Only Nonequivalent Comparison Group Design (12^th grade) were used. Interviews of students and teachers were used in the classic sense of triangulation. Data collection took place over the 2001–2002 school year. When controlling for pretest score, grade point average (GPA), gender, and ethnicity, environment‐based programs had a positive effect on 9^th grade students' critical thinking skills (p=.002). When controlling for GPA, gender, and ethnicity, environment‐based programs had a positive effect on 12^th grade students' critical thinking skills (p < .001) and disposition toward critical thinking (p < .001). The results of this study support the use of environment‐based education for improving critical thinking and can be used to guide future implementation.     

对西安市城镇高中生批判性思维的初步调查

This paper reports the development of critical thinking of urban high school students in the Chinese city of Xi’an. It presents the assessment of the students’ two components of critical thinking: dispositions towards critical thinking and critical thinking skills, using the California Critical Thinking Disposition Inventory and the California Critical Thinking Skills Test. Results show that the students’ dispositions toward critical thinking are at an average level while their critical thinking skills are very low. This research also shows that there is no significant difference between students from science classes and arts classes in their critical thinking dispositions while science students have a higher level of critical thinking skills. Students from advanced classes have a higher level of the two components of critical thinking than their counterparts from general classes. There are no differences between male students and female students in both components.      

A study of urban middle school students with high and low attitudes toward science

Scientific literacy is essential to survive in this technological world, but it appears that scientific literacy is not of high priority for many students. This research project was undertaken to gather demographic data, intentions to engage in science, and attitudes of urban, middle school students. Scores on the Simpson-Troost Attitude Instrument were analyzed using the Statistical Analysis System. Results indicate less than 50% of the students come from high-school-graduated parents who work full-time to support the family. Less than 50% of these students indicate any interest to engage in science at the high school level, yet many plan to enter a science-related career. A majority of the students possess an uncertain attitude toward their science teachers and science curricula. However, all possessed high achievement motivations, strong positive attitudes toward their families, and high self-concepts.     

Stimulation of thinking skills in high school students

The objective of this research was to examine the effects of the instruction method “thinking actively in an academic context (TAAC)” on thinking skills, creativity, self‐regulation and academic achievement. The design was pre‐test–intervention–post‐test with control group. The sample included 46 participants (aged 16 to 18 years), 24 experimental and 22 controls. Before and after application of the method, six instruments were used to measure thinking skills and academic achievement. The method, divided into eight stages, was followed in each didactic unit during an academic course. The method allows teaching the thinking skills, the creativity and the self‐regulation simultaneously with the syllabus content. The results showed that greater changes were obtained with the new method of instruction in all the dependent variables. Relevant scientific and educational implications are drawn from the study.     

The science support scale: Its appropriateness with high school students

Implementing the idea that more emphasis should be placed on student achievement in the affective domain is contingent upon the concurrent development of suitable instruments for the assessment of prescribed criteria. One such instrument, the Schwirian Science Support Scale (Tri-S scale), was reported in a recent NSTA publication as a promising tool for measuring student science support. Recent research using the Tri-S scale with high school pupils showed that scores on this instrument did not increase after the students had taken a tenth grade introductory course in biology. Further analysis indicated students of teachers scoring “high” in science support did not produce higher scores on the Tri-S scale than students studying biology from teachers “low” in science support. Reliability estimates using high school student scores were well below previous estimates using scores from college undergraduates. Factor analysis of inter-item correlations indicated that student interpretation of item meaning did not correspond to the five subtest structure of the Tri-S scale. Findings from this study demonstrate that the Tri-S scale is not an appropriate instrument for measuring attitudinal changes of tenth grade high school students. This study is suggestive of the fact that went and future instruments that purport to measure achievement in noncognitive areas should be carefully analyzed before they are recommended for use with specific populations.

Accelerating the development of formal thinking in middle and high school students II: Postproject effects on science achievement

A one-year lag was found between the effect of an intervention intended to promote formal operational thinking in students initially 11 or 12 years of age and the appearance of substantial science achievement in the experimental groups. A one-year lag was also reported on cognitive development: Whereas at the end of the two-year intervention the experimental groups were up to 0.9σ ahead of the control groups, one year later the differential on Piagetian measures had disappeared, but the experimentals now showed better science achievement of even greater magnitude. Although the control groups showed normal distribution both on science achievement and cognitive development, the experimental groups showed bi- or trimodal distribution. Between one-half and one-quarter of the students involved in the experiment in different groups showed effects of the order of 2σ both on cognitive development and science achievement; some students appeared unaffected (compared with the controls), and others demonstrated modest effects on science achievement. An age/gender interaction is reported: the most substantial effects were found in boys initially aged 12+ and girls initially 11+. The only group to show no effects was boys initially aged 11+. It is suggested that the intervention methods may have favored the abstract analytical learning style as described by Cohen 1986.     

Achievement goal orientation and the critical thinking disposition of college students across academic programmes

This study links achievement goal theory and models of critical thinking by investigating the relationship between motivational goals and the thinking dispositions of college students enrolled in five different academic programmes in Thailand (N = 1336, males = 32.9% and females = 67.1%). We found significant differences in goal orientations and thinking dispositions across academic programmes. For example, nursing students were significantly more mastery goal-oriented and had a higher level of ‘analytical’ thinking disposition than students in business, engineering, education and vocational programmes. Multiple regression analysis found a positive influence of mastery goals and a negative influence of performance avoidance goals on the levels of critical thinking dispositions. We found that critical thinking dispositions are related to goal orientation response patterns and vary with the curricular context.     

A cluster analysis of high school science classroom environments and attitude toward science

This study provides a test of a theory which suggests that student perceptions of their classroom environment affect their attitudes toward science. Using the statistical technique of cluster analysis, 27 high school science classes were divided into three distinct clusters which were most distinguishable by the amount of involvement, affiliation with students, teacher support, order and organizations, and innovative teaching strategies. One of the clusters provided a classroom environment which was significantly different from the other two and the students in that environment had more positive attitudes toward science. The dimensions of the classroom environment which make a difference are those which teachers may develop and change in order to enhance the science attitudes and, possibly, the science achievement of their students.     

Interpreting experimental data: the views of upper secondary school and university science students

In this paper we examine students' views about the interpretation of experimental data within a specified science context. A written survey was completed by 731 science students drawn from upper secondary schools and universities in five European countries. An additional 19 upper secondary science students were interviewed individually after they had completed the survey. A minority of students emphasized the role of models in the interpretation of the data, despite the emphasis placed on theoretical models within the survey text. A substantial proportion of respondents focused on the quantity and quality of the data to be interpreted. Post-survey interviews showed that many students had difficulty in articulating a view concerning the role of theoretical models. Our data support previous studies, typically involving younger respondents, which have found that science students tend not to recognize the role of theoretical models in the interpretation of data.

Accelerating the development of formal thinking in middle and high school students

In an attempt to accelerate the development of formal operations in average young adolescents, intervention lessons relating to all formal schemata were designed in the context of school science courses. Over a period of two years, up to 30 intervention lessons were given by science teachers to their classes in eight schools. Boys who started the program aged 12+ showed a pre-posttest effect size on Piagetian tests of 0.89 SD compared with control classes. In terms of British norms for the development of operational thinking this was a mean change from the 51st to the 74th percentile. Neither the middle school students nor the 12+ girls showed greater gain than the controls. Gains were shown by girls in one 11+ class and in the two 11+ laboratory classes. In the laboratory school students given intervention lessons by the researchers maintained their gains over controls in formal operations at a delayed posttest one year after cessation of the program. There was no effect on tests of science achievement during the intervention. It was argued that the interventions needed to be accompanied by in-service training designed to enable teachers to change their teaching style in line with their students' increased operational thinking capacity.
