The Effects of Dichotomous Attitudes toward Science on Interest and Conceptual Understanding in Physics

The literature on students' attitudinal constructs in science education asserts that students hold dichotomous attitudes toward science (AS). For instance, studies from the Relevance of Science Education project reveal that students possess negative attitudes in terms of their favourableness toward school science, preference toward scientific careers, and emotional states toward science (negative intrinsic AS), despite their positive perception that science is important for society (positive extrinsic AS). The issue demands in‐depth examination, since not enough science educators have studied the effects of the dichotomous AS on science education. Rather, they have attempted to improve the uncategorised AS for stimulating student achievement in science education. Hence, the aim of this study is to clarify how the dichotomous attitude (intrinsic AS and extrinsic AS) relates to the two educational products in science: interest inventory and conceptual understanding. One hundred and sixteen physics learners in Japan were sampled for fitting the structural equation model in this study. Our final model validated by LISREL suggests that intrinsic AS exclusively stimulate students' interest and conceptual understanding in physics, while extrinsic AS fail to play their expected role. Finally, features of the sampled 10th‐graders and their dichotomous AS are further interpreted with the prevalent concept of the hidden curriculum.     

EFFECTS OF AN INTERGENERATIONAL FRIENDLY VISIT PROGRAM ON THE ATTITUDES OF FOURTH GRADERS TOWARD ELDERS

This article describes the effects of an intergenerational friendly visit program on the attitudes toward the elders of one fourth grade class. Students visited with their elder "special friends" at a nursing home every week for five months. In-class lessons regarding students' knowledge and attitudes toward elders prepared students for the visits. The results of this qualitative study indicated that students gained a raised level of awareness regarding elders and the aging process. Their attitudes revealed a realistic view of both the positive and negative aspects of aging. Their attitudes toward their "special friends" were consistently positive and their empathy increased during the course of the study.     

School Work,Homework and Gender

This paper explores female and male students' attitudes towards school work in terms of application and achievement. The data are drawn from interviews with students, teachers, careers officers and welfare officers in three semi‐rural comprehensive schools in one local education authority (LEA) [1]. (The students were in their last year of compulsory schooling, Year 11, and were aged 16 [2].) The three schools had invited the authors to explore why boys were achieving below their potential in terms of course work and end of course grades. The findings of the study show how school, peer group and community factors influence students' attitudes towards school work and homework. However, the situation is not just one of boys' under‐performance: the pattern of girls' achievement at 16 (the school leaving age) is not always carried through post‐16 or into career destinations. The problem is one of ‘equalising opportunities’ for all young people, taking into account the different patterns of need at different stages in their school careers.     

Skill and will: The role of motivation and cognition in the learning of college chemistry

This study investigated how students' level of motivation and use of specific cognitive and self-regulatory strategies changed over time, and how these motivational and cognitive components in turn predicted students' course performance in chemistry. Participants were 458 students enrolled in introductory college chemistry classes. Participants' motivation and strategy use were assessed at three time points over the course of one semester using self-report instruments. Results showed an overall decline in students' motivational levels over time. There was also a decline in students' use of rehearsal and elaboration strategies over time; students' use of organizational and self-regulatory strategies increased over time. These trends, however, were found to vary by students' achievement levels. In terms of the relations of motivation and cognition to achievement, the motivational components of self-efficacy and task value were found to be the best predictors of final course performance even after controlling for prior achievement.     

Influence of resequencing general science content on the science achievement,attitudes toward science,and interest in science of sixth grade students

This study was designed to determine the influence of resequencing general science content on sixth grade students' science achievement, attitudes toward science, and interest in science. Resequencing content was accomplished for experimental group students through revising the order of textbook chapters in a general science course, in order to clarify content structure and establish interrelationships among major concepts. The subjects were 203 sixth grade learners randomly assigned to the two treatment groups of resequenced content and nonresequenced content. The findings revealed that students for whom content structure was clarified through resequencing general science chapters exhibited significantly higher science achievement, significantly more positive attitudes toward science, and significantly greater interest in science than students for whom general science content was not resequenced.     

A survey of antecedents of attitudes toward science

Relationships among attitudes of students toward science, as measured by the WASP (Wareing Attitudes Toward Science Protocol), perceived antecedents of such attitudes, and class achievement or performance indicated by reported grades were investigated for a survey sample of 1,740 students in 87 high school science classes from five communities. Additionally, students' self-reported number of tests administered in a given course, perceived rewards, degree of stress, and internal structure of the course were examined as potential predictor variables. Results indicate a significant correspondence between report card grades, degree of structure, degree of stress, gender, degree of rewards, number of tests, and students' attitudes toward science.     

Effectiveness of conceptual change instruction on understanding of heat and temperature concepts

This study investigated the differential effects of two modes of instructional program (conceptual change oriented and traditionally designed) and gender difference on students' understanding of heat and temperature concepts, and their attitudes toward science as a school subject. The subjects of this study consisted of 72 seventh grade students from two General Science Classes taking the course from the same teacher. Each teaching method was randomly assigned to one class. The experimental group received reinforcement via the conceptual change texts while the control group utilized traditionally designed science texts over a period of four weeks. Analysis of covariance was used. Logical thinking ability was taken as a covariate. The results showed that the conceptual change oriented instruction produced significantly greater achievement in understanding of heat and temperature concepts. The result for science attitudes as a school subject showed no significant difference between the experimental and control groups. Also, no significant difference was found between the performance of females and that of males in terms of learning heat and temperature concepts and attitudes toward science, but the interaction of treatment regarding to gender was significant for learning the concepts. In addition, it was found that students' logical thinking ability accounted for a significant portion of variation in heat and temperature concepts achievement.     

The Educational and Behavioral Impacts of the Ewing Marion Kauffman Charter School

The Kauffman School is a public charter school serving students from low-income neighborhoods in Kansas City, Missouri. This paper used a matched comparison group design to estimate the impacts of the Kauffman School on student achievement, attendance, and suspensions. We found that the Kauffman School had large positive impacts on student achievement in mathematics, reading, and science. This paper also used qualitative data to explore possible mechanisms for the school's effects. We found evidence that the Kauffman School's hallmarks are being implemented faithfully, and that stakeholders believe the school's methods are having a positive influence on students' attitudes and performance     

Cognitive foundations for science assessment design: Knowing what students know about evolution

To improve assessments of academic achievement, test developers have been urged to use an “assessment triangle” that starts with research‐based models of cognition and learning [NRC (2001) Knowing what students know: The science and design of educational assessment. Washington, DC: National Academy Press]. This approach has been successful in designing high‐quality reading and math assessments, but less progress has been made for assessments in content‐rich sciences such as biology. To rectify this situation, we applied the “assessment triangle” to design and evaluate new items for an instrument (ACORNS, Assessing Contextual Reasoning about Natural Selection) that had been proposed to assess students' use of natural selection to explain evolutionary change. Design and scoring of items was explicitly guided by a cognitive model that reflected four psychological principles: with development of expertise, (1) core concepts facilitate long‐term recall, (2) causally‐central features become weighted more strongly in explaining phenomena, (3) normative ideas co‐exist but increasingly outcompete naive ideas in reasoning, and (4) knowledge becomes more abstract and less specific to the learning situation. We conducted an evaluation study with 320 students to examine whether scores from our new ACORNS items could detect gradations of expertise, provide insight into thinking about evolutionary change, and predict teachers' assessments of student achievement. Findings were consistent with our cognitive model, and ACORNS was revealing about undergraduates' thinking about evolutionary change. Results indicated that (1) causally‐central concepts of evolution by natural selection typically co‐existed and competed with the presence of naïve ideas in all students' explanations, with naïve ideas being especially prevalent in low‐performers' explanations; (2) causally‐central concepts were elicited most frequently when students were asked to explain evolution of animals and familiar plants, with influence of superficial features being strongest for low‐performers; and (3) ACORNS scores accurately predicted students' later achievement in a college‐level evolution course. Together, findings illustrate usefulness of cognitive models in designing instruments intended to capture students' developing expertise. © 2012 Wiley Periodicals, Inc.

Generation Psy: Student characteristics and academic achievement in a three-year problem-based learning bachelor program

This study investigated the simultaneous impact of demographic, personality, intelligence, and (prior) study performance factors on students' academic achievement in a three-year academic problem-based psychology program. Information regarding students' gender, age, nationality, pre-university education, high school grades, Big Five personality traits, intelligence (i.e., numerical, verbal, spatial), observed learning activities, and self-study time was collected among almost 1800 students enrolled in this psychology bachelor program at Erasmus University Rotterdam between 2003 and 2009. Academic achievement was measured by students' yearly number of acquired credit points, a course test, and a knowledge progress test. Multiple regression analyses showed that observed learning activities, first- and second-year performance, high school grades, conscientiousness, and verbal ability were most strongly and consistently related to academic achievement in the bachelor. Other student factors also contributed to academic achievement, but their influence was less prominent and mainly restricted to the first year. These results suggest that (prior) educational achievements and observable learning activities are most important for academic success in a problem-based learning bachelor program.     

Variation among schools on classroom practices in science based on TIMSS‐1999 in Turkey

The purpose of this study was to investigate the differences among schools using student responses in the Trends in Mathematics and Science Study–1999 (TIMSS‐99) data. Schools were classified into two groups based on eighth grade students' overall achievement in science. Two different discriminant function analyses were performed to distinguish high‐ and low‐performing schools, based both on classroom practices and factor structures (student‐centered activities, teacher‐centered activities, attitudes toward technology use, socioeconomic status [SES], and doing well in science). The results indicate that there were significant differences between the two classifications of schools on ten variables regarding classroom practices and activities, and 29 variables regarding classroom practices, attitudes toward science, use of the computer and overhead projector (OHP), parental background characteristics, and need to do well in science. Contrary to general expectations, technology use (computer, OHP, etc.) was found to be negatively related to science achievement. Teachers should be trained on how to use technology in their classrooms. Turkey recently revised its curriculum to a student‐centered approach and this might increase students' ability to transfer knowledge into real life. Teachers and schools should pay more attention to SES effects. Teachers should also work toward building students' confidence in science. © 2007 Wiley Periodicals, Inc.

Students' achievement in relation to reasoning ability,prior knowledge and gender

This study investigated students' achievement regarding photosynthesis and respiration in plants in relation to reasoning ability, prior knowledge and gender. A total of 117 eighth‐grade students participated in the study. Test of logical thinking and the two‐tier multiple choice tests were administered to determine students' reasoning ability and achievement, respectively. An analysis of covariance (ANCOVA) was conducted to assess the effect of reasoning ability on students' achievement. The independent variable was the reasoning ability (low, medium, high), the dependent variable was the scores on the two‐tier test. Students' grades in science in previous year were used as a covariate. Analysis revealed a statistically significant mean difference between students at high and low formal levels with respect to achievement. Stepwise multiple regression analysis revealed that reasoning ability, prior knowledge and gender were significant predictors of students' achievement in photosynthesis and respiration in plants, explaining 42% of the variance.     

College students' perceptions of the theory of evolution

Although a well‐corroborated scientific theory, the theory of evolution has continued to cause dilemmas for some individuals who have not easily been able to accommodate the concepts of this theory within their “cognitive culture.” The reason lies in the overlap of some ideas that the theory advocates with other social, epistemological, and religious beliefs. This study describes how 11 college biology students who completed a course on the theory of evolution perceive the relationship among their epistemological beliefs about science, their beliefs about religion, and their perception of nature and causality and their position regarding the theory of evolution. It also compares the different positions of the students to that of the course instructor. Questionnaires and semistructured interviews were used to collect data. Qualitative methods were used to analyze the data and identify the various positions of the students and course instructor. The students' positions ranged from complete acceptance to complete rejection of the theory of evolution. The results suggest that students' personal beliefs should not be dismissed or underestimated when teaching the theory of evolution. © 2008 Wiley Periodicals, Inc.

Student affect and conceptual understanding in learning chemistry

This study explores the relationship between affective and cognitive variables in grade 9 chemistry students (n = 73). In particular, it explores how students' situational interest, their attitudes toward chemistry, and their chemistry‐specific self‐concept influence their understanding of chemistry concepts over the course of a school year. All affective variables were assessed at two time points: at the middle of the first semester of grade 9, and at the end of the second semester of grade 9, and then related to students' postinstructional understanding of chemical concepts. Results reveal that none of the affective variables measured at the earliest time point have a significant direct effect on postinstructional conceptual understanding. Looking at the different affective variables as intermediary constructs, however, reveals a pattern in which self‐concept and situational interest measured at the middle of grade 9 contribute to self‐concept measured at the end of grade 9, which in turn, has a positive, significant effect on students' postinstructional conceptual understanding. These results reveal the importance of a strong and positive self‐concept, the feeling of doing well in the chemistry class, for developing a meaningful understanding of scientific concepts. © 2006 Wiley Periodicals, Inc.

An exploration of Illinois students' attitudes toward science using multivariate multilevel modeling with a cross-sectional sample of responses from grades 5 through 10

The present study examined students' attitudes toward science and associated constructs, based on the theories of reasoned action and planned behavior, and explored relationships between individual and school-related variables common to the research literature. Responses from 1,291 students in Grades 5 through 10 were collected using the 30-item Behaviors, Related Attitudes, and Intentions toward Science (BRAINS) Survey along with background information questions. Additional self-report data were collected from teachers (n = 56; 82.4%) in participating schools (n = 68) to obtain information about their education and experience, characteristics and practices, as well as other classroom variables, which could influence students' outlook. Student information, teacher data collected, and other data compiled about participating schools, were used to explore patterns in students' attitudes, beliefs, and intentions. These variables were used to generate multivariate multilevel models through a forward construction process. The final model presented favors individual variables to explain differences in students' responses on all five of the BRAINS subscales, more than group-level variables captured. Of the predictor variables explored, students' perceived science ability and frequency of talk with family were influential on all subscales, and increasing these variables had a positive effect on the estimated mean scores according to the final model presented. Findings from this study also include commonly observed relationships, such as the decline in attitudes over time, but these were found to be less pervasive in this sample. The paper concludes with a discussion about the comparative ineffectiveness of teacher and school-related variables in explaining students' attitudes toward science in this study, in light of design decisions and limitations, to guide future investigations.     

Students' cognitive focus during a chemistry laboratory exercise: Effects of a computer‐simulated prelab

To enhance the learning outcomes achieved by students, learners undertook a computer‐simulated activity based on an acid–base titration prior to a university‐level chemistry laboratory activity. Students were categorized with respect to their attitudes toward learning. During the laboratory exercise, questions that students asked their assistant teachers were used as indicators of cognitive focus. During the interviews, students' frequency and level of “spontaneous” use of chemical knowledge served as an indicator of knowledge usability. Results suggest that the simulation influenced students toward posing more theoretical questions during their laboratory work and, regardless of attitudes, exhibiting a more complex, correct use of chemistry knowledge in their interviews. A more relativistic student attitude toward learning was positively correlated with interview performance in both the control and treatment groups. © 2007 Wiley Periodicals, Inc.

Student Perceptions as Distance Learners in Internet-Based Courses

With the increasing prevalence of Internet-based courses in higher education, it is important to examine students' experiences to provide an optimal learning environment. This research found that students reporting positive attitudes about their online course experience exhibited attributes of constructivist learners, including self-direction. Students with negative attitudes seemed less able to understand the course content and to trust self-assessment of their learning, and reported the need for more guidance. In addition, students' expectations were a determining influence in their online course experience and strategies. This study also explored strategies that students use to be successful and discusses ways by which instructors can recognize and meet the needs of a wide range of learners.     

Contextualizing instruction: Leveraging students' prior knowledge and experiences to foster understanding of middle school science

Contextualizing science instruction involves utilizing students' prior knowledge and everyday experiences as a catalyst for understanding challenging science concepts. This study of two middle school science classrooms examined how students utilized the contextualizing aspects of project‐based instruction and its relationship to their science learning. Observations of focus students' participation during instruction were described in terms of a contextualizing score for their use of the project features to support their learning. Pre/posttests were administered and students' final artifacts were collected and evaluated. The results of these assessments were compared with students' contextualizing scores, demonstrating a strong positive correlation between them. These findings provide evidence to support claims of contextualizing instruction as a means to facilitate student learning, and point toward future consideration of this instructional method in broader research studies and the design of science learning environments. © 2007 Wiley Periodicals, Inc.

Secondary School Students' Attitudes Towards Science

Four hundred and fifty‐one students' attitudes towards science were investigated. Two types of instruments (questionnaire and Attitude Scale) were used to collect the data. The results show that the students in general hold a favourable attitude towards science; male students have more positive attitude towards science than female students; the type of school (science‐school, single‐sex school or general secondary school) attended have an effect on the students' attitudes to science. The low enrollment in science is not due to the lack of interest or negative attitudes to the subject but may be due to some other variables that need to be investigated.     

Concentrations and Methods

This study compared 248 graduating seniors with 301 beginning juniors at 10 bachelor's-level social work programs in the Northeast concerning their knowledge and attitudes regarding working with substance-abusing clients. Graduating seniors demonstrated modestly higher levels of knowledge and only slightly more positive attitudes toward working with this population. In a multivariate analysis, however, having taken a substance abuse course in college or training in settings outside of school improved students' attitudes in this regard. The students' ethnic/racial identity and personal exposure to substance abuse through family, close friends, or self also had a significant impact on their knowledge and attitudes.
