Construction and Validation of an Instrument to Measure Taiwanese Elementary Students’ Attitudes toward Their Science Class

The main purpose of this study is to develop a valid and reliable instrument for measuring the attitudes toward science class of fourth‐ and fifth‐grade students in an Asian school culture. Specifically, the development focused on three science attitude constructs—science enjoyment, science confidence, and importance of science as related to science class experiences. A total of 265 elementary school students in Taiwan responded to the instrument developed. Data analysis indicated that the instrument exhibited satisfactory validity and reliability with the Taiwan population used. The Cronbach’s alpha coefficient was 0.93 for the entire instrument indicating a satisfactory level of internal consistency. However, both principal component analysis and parallel analysis showed that the three attitude scales were not unique and should be combined and used as a general “attitudes toward science class” scale. The analysis also showed that there were no gender or grade‐level differences in students’ overall attitudes toward science class.     

My Attitudes Toward Science (MATS): the development of a multidimensional instrument measuring students’ science attitudes

The number of students in the United States choosing science, technology, engineering or mathematics careers is declining at a time when demand for these occupations is rapidly increasing. Numerous efforts have been undertaken to reverse this trend, yet results are uncertain. One’s attitude is key to many choices one makes, and this includes, for many, what career is pursued. Hence, teachers, informal science educators and researchers often wish to measure children’s attitudes towards science using a pretest and a posttest to determine the effects of a curriculum, an activity or an intervention. However, measuring children’s attitudes toward science has been problematic because of both the limited use of basic psychometrics in checking reliability and validity of instruments and the lack of a single construct of students’ attitudes towards science being surveyed. This article reports the development and testing of an instrument for measuring students’ science attitudes across several dimensions. Thirty-two scientists and teachers from the northeastern and south central United States participated in content validity trials. The instrument was field tested with 549 children (92 elementary-school students, 327 middle-school students and 130 high-school students) from 6 rural and suburban school systems located in the northeastern United States to determine inter-item reliability for each dimension. The resulting instrument, entitled My Attitudes Toward Science (MATS), has 40 items that measure four dimensions: (1) Attitude towards the subject of science; (2) Desire to become a scientist; (3) Value of science to society; and (4) Perception of scientists. The MATS, as a multidimensional instrument, can measure several facets of students’ attitude toward science and is designed to be used across grades levels and to be scored easily.     

A quantitative and qualitative inquiry into the attitudes toward science of nonscience college students

The attitudes toward science of nonscience college students were investigated using quantitative and qualitative forms of inquiry. Quantitative methods were used to determine (a) how attitudes toward science of nonscience college students compare with attitudes of science majors, and (b) whether attitudes toward science change with instruction. Qualitative assessment was used to investigate attitude development as it relates to science. The subjects were 102 nonscience students and 81 science students. Six attitudinal variables were investigated using the Attitudes Toward Science Inventory (ATSI) as the quantitative instrument. Hotelling's T² showed a significant difference (p = 0.0001) in attitudes between the two groups. T tests revealed significant differences between the two groups for all six variables. A significant difference (p = 0.0001) was found between pretest and posttest results for the nonscience students. T tests showed significant differences between the two sets of scores for all six variables, indicating a favorable change in attitudes. An interview questionnaire was used to investigate factors contributing to attitude development. The interview results suggested that attitudes toward science are formed by interactions of both school and nonschool variables.     

Relationships of attitude toward classroom environment with attitude toward and achievement in science among tenth grade biology students

The purpose of the study was to examine the relationship of classroom environment to attitudes toward science and achievement in science among tenth grade biology students. An attitude instrument was administered at three times during the school year to measure student attitudes toward science and the classroom environment. The classroom environment measures examined six areas: emotional climate of the science classroom, science curriculum, physical environment of the science classroom, science teacher, other students in the science classroom, and friends attitudes toward science. Student achievement in science was measured by teacher reported semester grades. The results of the study indicated: (1) student attitudes toward the classroom environment predicted between 56 to 61% of the variance in attitudes toward science, (2) student attitudes toward the classroom environment predicted between 5 to 14% of the variance in achievement in science, (3) student attitudes toward science and attitudes toward the classroom environment predicted between 8 and 18% of the variance in achievement in science.     

A study of the perceptual orientation of community college students and their attitudes toward science as they relate to science achievement

The purpose of this study was to investigate the perceptual orientation and attitudes toward science of freshman community college students and the relationship of these characteristics toward science achievement. It was found that perceptual orientation (field independence-dependence) was related to attitudes toward science. In addition, it was found that students who were field independent and possessed a positive attitude toward science scored significantly higher on the science achievement test than students who were field dependent and possessed a negative attitude toward science.     

Development and Validation of an Instrument to Measure University Students’ Biotechnology Attitude

The impact of biotechnologies on peoples’ everyday lives continuously increases. Measuring young peoples’ attitudes toward biotechnologies is therefore very important and its results are useful not only for science curriculum developers and policy makers, but also for producers and distributors of genetically modified products. Despite of substantial number of instruments which focused on measuring student attitudes toward biotechnology, a majority of them were not rigorously validated. This study deals with the development and validation of an attitude questionnaire toward biotechnology. Detailed information on development and validation process of the instrument is provided. Data gathered from 326 university students provided evidence for the validity and reliability of the new instrument which consists of 28 attitude items on a five point likert type scale. It is believed that the instrument will serve as a valuable tool for both instructors and researchers in science education to assess students’ biotechnology attitudes.     

Development of the attitude toward science in school assessment and its use to investigate the relationship between science achievement and attitude toward science in school

There is much interest in science courses in high school and student attitudes toward those courses. A valid and reliable instrument that measures such attitudes is not available. This study first developed and validated the Attitude toward Science in School Assessment (ATSSA). The instrument was used to evaluate the relationship between such attitude and achievement in science. A low correlation was found between attitude and various achievement tests. A moderate correlation was found between attitude and achievement that included an evaluation of the quality of work, as in a course grade.     

Measuring Primary Teachers' Attitudes Toward Teaching Science: Development of the Dimensions of Attitude Toward Science (DAS) Instrument

In this article, we present a valid and reliable instrument which measures the attitude of in-service and pre-service primary teachers toward teaching science, called the Dimensions of Attitude Toward Science (DAS) Instrument. Attention to the attitudes of primary teachers toward teaching science is of fundamental importance to the professionalization of these teachers in the field of primary science education. With the development of this instrument, we sought to fulfill the need for a statistically and theoretically valid and reliable instrument to measure pre-service and in-service teachers' attitudes. The DAS Instrument is based on a comprehensive theoretical framework for attitude toward (teaching) science. After pilot testing, the DAS was revised and subsequently validated using a large group of respondents (pre-service and in-service primary teachers) (N = 556). The theoretical underpinning of the DAS combined with the statistical data indicate that the DAS possesses good construct validity and that it proves to be a promising instrument that can be utilized for research purposes, and also as a teacher training and coaching tool. This instrument can therefore make a valuable contribution to progress within the field of science education.     

INVESTIGATING THE EFFECTIVENESS OF INQUIRY-BASED INSTRUCTION ON STUDENTS WITH DIFFERENT PRIOR KNOWLEDGE AND READING ABILITIES

This study examined the differential impacts of an inquiry-based instruction on conceptual changes across levels of prior knowledge and reading ability. The instrument emphasized four simultaneously important components: conceptual knowledge, reading ability, attitude toward science, and learning environment. Although the learning patterns and effect size analyses indicated that students from all subgroups demonstrated substantial gains on weather concepts, students from the low prior conceptual knowledge group demonstrated greater gains in conceptual knowledge than subgroups with more prior knowledge; and these gains remained stable 3 weeks after the instruction ceased. However, students from the low language proficiency group showed the least gains in conceptual knowledge. Students’ prior knowledge and reading ability were found to be positively and significantly associated to conceptual development. Recent perspectives on the role of language in science education and suggestions that support learning during instruction are briefly described.     

The Strong Vocational Interest Blank and Occupational Proficiency*

Abstract

While the original Estes Attitude Scale Toward Reading is a valid and reliable instrument for measuring the attitudes of secondary students toward reading, its vocabulary and sentence structure made it too difficult to use with elementary students. The purposes of this study were: (a) to simplify the Estes Scale without changing the concepts, (b) to validate the modified instrument, and (c) to investigate the relationship between attitude and reading achievement among elementary students. A total of 697 students from urban and rural areas and from grade levels three through six were involved. Student and teacher reading criterion measures, used to validate the Estes Scale, were employed to assure validation consistency. With the attitude scale as the treatment variable, and grade level and criterion measures as the classification variables, several two-way ANOVAs were computed for each criterion measure. It was found that the main effects, grade level and criterion measure, were highly significant for each ANOVA. Correlation between attitude and achievement scores was significant but low. It was concluded that the modified instrument can be used as a screening device to differentiate students with high and low attitudes toward reading.     

Effects of discovery and expository instructional methods on the attitude of students to biology

The effects of discovery and expository instructional methods on the attitude of students to biology was investigated. The sample consisted of 240 Form IV biology students randomly drawn from six selected secondary schools in the Oyo state of Nigeria. They were assigned into two groups—experimental and control. The experimental group was exposed to the discovery method, and the control group was taught using the expository method. The science class of Form IV in each of the six schools was selected intact for the study. A nonrandomized pretest-posttest control group design was employed. The major instrument was the 40–item Scientific Attitude Questionnaire (SAQ). It is a Likert-type questionnaire using five scales. Two hypotheses were tested. Analyses of the results showed that the experimental group evinced a significantly more favorable attitude to biology than the control group (t = 8.87, p < 0.01). It was also found that the high, average-, and low-ability groups in the experimental class evinced a more favorable attitude to biology than their counterparts in the control class. However, there was no significant difference in the attitude of male and female students exposed to the discovery and expository methods (F1,227 = 0.07, p > 0.999). The article concludes with a recommendation that science learning using the discovery method may enable the learner to evince more a favorable attitude toward problem recognition and problem solving than when learning is done by the expository method.     

The effects of matching instructional strategy with selected student characteristics on ninth grade physical science students' attitudes and achievement

The study investigated the benefits of a matching model of instruction for students enrolled in ninth grade physical science classes in one high school in a small, urban school district. Based on social learning theory, three independent variables were identified for purposes of matching: need level, cognitive style, and locus of control; attitude and achievement outcomes served as the dependent variables. Results of separate analyses of covariance revealed that attitude toward science in general improved with matching, but achievement, attitude toward physical science, attitude toward instruction, and attitude toward the teacher did not improve. Recommendations for subsequent “matching” experiments are discussed in light of the findings in this investigation.     

A REEXAMINATION OF THE FACTOR STRUCTURE OF THE AGING SEMANTIC DIFFERENTIAL USING A GENERALIZED SOCIAL OBJECT

During the past thirty years, gerontologists and educational professionals have attempted to determine the effects of teaching courses in gerontology and aging on the attitudes of students. The results of studies of attitude toward the elderly before and after such courses have been mixed. This study discusses some of the problems in assessing attitudes toward the elderly and reexamines the Aging Semantic Differential, an instrument developed in an attempt to clarify the factors accounting for attitudes toward the elderly and to provide a viable instrument for attitude measurement. The instrument was reported to consist of three underlying factors. It was reported that factor scales could be used to do profile analyses to determine variations in attitude toward different age groups. The original instrument was developed utilizing a social object of young, middle‐aged, and old men. In many of the studies conducted with the instrument, a more generalized social object such as old person has been used. The current study attempts to determine if three factors are appropriate, as originally reported, and whether the items reported to load on the original three factors are the same if a more generalized social object is used. Suggestions for appropriate use of the Aging Semantic Differential by educational professionals who wish to do a profile analysis of attitude and attitude change as a result of educational intervention are included.     

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.     

STUDENT INTEREST IN TECHNOLOGY AND SCIENCE (SITS) SURVEY: DEVELOPMENT,VALIDATION, AND USE OF A NEW INSTRUMENT

This study presents the systematic development, validation, and use of a new instrument for measuring student interest in science and technology. The Student Interest in Technology and Science (SITS) survey is composed of 5 sub-sections assessing the following dimensions: interest in learning science, using technology to learn science, science careers, technology careers, and attitudes toward biotechnology. Our development process included review of existing instrumentation, pilot testing, and expert panel review. The resulting instrument was administered before and after implementation of a biotechnology intervention which used a computer-based game to engage learners in the use of biotechnology to address a societal issue. We employed item response theory (IRT) to explore instrument validity and precision. Results of the psychometric analyses suggest that the SITS survey has a well-defined structure and meets IRT assumptions. Difficulty and discrimination parameters as well as reliability analyses indicate that SITS items provide useful measures of student interest. Finally, we use the SITS to explore the extent to which the intervention used in this study supports changes in student interest and association between students’ interest and related content knowledge. Implications for the future use of this instrument are discussed.     

Middle school students’ attitudes toward physical education

The purpose of this study was to determine middle school students’ attitudes toward physical education using an attitude instrument grounded in attitude theory. In addition, this investigation also sought to ascertain if gender and grade level influence student attitudes toward the subject matter. Participants for this study were 995 students from grades 6 to 8. A previously validated attitude instrument based on a two-component view of attitude with scores that showed evidence of reliability and validity was used. Overall all students had moderately positive attitudes toward physical education. There was, however, a decline in attitude scores as students progressed in grade level. Higher grades had lower mean scores.     

Design,validation, and use of an evaluation instrument for monitoring systemic reform

Over the past decade, state and national policymakers have promoted systemic reform as a way to achieve high‐quality science education for all students. However, few instruments are available to measure changes in key dimensions relevant to systemic reform such as teaching practices, student attitudes, or home and peer support. Furthermore, Rasch methods of analysis are needed to permit valid comparison of different cohorts of students during different years of a reform effort. This article describes the design, development, validation, and use of an instrument that measures student attitudes and several environment dimensions (standards‐based teaching, home support, and peer support) using a three‐step process that incorporated expert opinion, factor analysis, and item response theory. The instrument was validated with over 8,000 science and mathematics students, taught by more than 1,000 teachers in over 200 schools as part of a comprehensive assessment of the effectiveness of Ohio's systemic reform initiative. When the new four‐factor, 20‐item questionnaire was used to explore the relative influence of the class, home, and peer environment on student achievement and attitudes, findings were remarkably consistent across 3 years and different units and methods of analysis. All three environments accounted for unique variance in student attitudes, but only the environment of the class accounted for unique variance in student achievement. However, the class environment (standards‐based teaching practices) was the strongest independent predictor of both achievement and attitude, and appreciable amounts of the total variance in attitudes were common to the three environments. © 2001 John Wiley & Sons, Inc.

Relationship among laboratory instruction,attitude toward science,and achievement in science knowledge

This study investigated the use of a hands-on laboratory program as a means of improving student attitude toward science and increasing student achievement levels in science knowledge. Using a posttest-only control group design, curriculum referenced objective examinations were used to measure student achievement in science knowledge, and a posttest Q-sort survey was used to measure student attitude toward science. A one-way analysis of variance compared the groups' differences in achievement and attitude toward science. Analysis of covariance was used to determine the effect of the laboratory treatment on the dependent achievement variable with attitude toward science as the covariable. The findings showed that students who had regular laboratory instruction (a) scored significantly higher (p < .01) on the objective examination of achievement in science knowledge than those who had no laboratory experiences; (b) exhibited a moderate, positive correlation (r = .406) between their attitude toward science and their achievement; and (c) scored significantly higher (p < .01) on achievement in science knowledge after these scores were adjusted on the attitude toward science covariable. There were no significant differences in achievement or attitude toward science for the limited English proficiency groups. It was concluded that laboratory instruction influenced, in a positive direction, the students' attitude toward science, and influenced their achievement in science knowledge. It was recommended that science instruction include a regular laboratory experience as a demonstrated viable and effective instructional method for science teachers. This model of science instruction has been shown to be effective with students of diverse backgrounds who live within large urban centers. J Res Sci Teach 34: 343–357, 1997.
