Understanding motivational structures that differentially predict engagement and achievement in middle school science

Middle school has been documented as the period in which a drop in students’ science interest and achievement occurs. This trend indicates a lack of motivation for learning science; however, little is known about how different aspects of motivation interact with student engagement and science learning outcomes. This study examines the relationships among motivational factors, engagement, and achievement in middle school science (grades 6–8). Data were obtained from middle school students in the United States (N?=?2094). The theoretical relationships among motivational constructs, including self-efficacy, and three types of goal orientations (mastery, performance approach, and performance avoid) were tested. The results showed that motivation is best modeled as distinct intrinsic and extrinsic factors; lending evidence that external, performance based goal orientations factor separately from self-efficacy and an internal, mastery based goal orientation. Second, a model was tested to examine how engagement mediated the relationships between intrinsic and extrinsic motivational factors and science achievement. Engagement mediated the relationship between intrinsic motivation and science achievement, whereas extrinsic motivation had no relationship with engagement and science achievement. Implications for how classroom practice and educational policy emphasize different student motivations, and in turn, can support or hinder students’ science learning are discussed.     

The relationship between affect and achievement in science

The relationship between affect and achievement in science was examined in two stages. First, a model was developed and tested for science-related affect, the complex of students' attitudes toward, interests in, and perceptions about science at school. The LISREL approach to path analysis was used to demonstrate the fit of the model to data collected from grade 8 students in two different schools on two different occasions. In the second stage of the research, multiple linear regression was used to examine the direction of the relationship between science related affect and achievement and to apportion variance common between previous and subsequent achievement and the components of science-related affect. It was found that affect is related more strongly to previous than subsequent achievement and that much of the common variance can be attributed to students' perceptions of their competence in science.     

Background aptitude and school factors related to achievement in year 12 science subjects

Conclusion The foregoing analyses suggest that achievement in Year 12 students was not related to either the use of exploratory teaching methods or the standard of science facilities. Possibly this was due to the fact that only senior students who had chosen to study science were included in the investigation. These results are based on data from Year 12 students who had chosen to study science and may therefore be different in important respects from other Year levels. It is possible that data from a sample of the whole age group in junior secondary school could yield a different pattern of relationships. Other studies (Ainley, 1978c) have suggested that in the junior secondary area the provision of better facilities was associated with enriched science learning experiences. Perhaps the Australian Science Facilities Programme would have been of greater benefit had it been directed more to the junior science area rather than to the senior science specialities.     

Negative school factors and their influence on math and science achievement in TIMSS 2003

The aim of the present study was to conduct an analysis of TIMSS (Trends in International Mathematics and Science Study) 2003 database and to determine how negative school factors, such as aggression, are associated to the mathematical and science achievement of students. The analyses were conducted separately for national and international data. National analyses for Slovenia show significant associations between math and science achievement and the experience of aggressive behaviour. Students who experienced aggressive behaviour scored lower in math and science, both in the fourth and in the eighth grade. The results of the regression analysis show that negative factors, such as aggressive behaviour, are good predictors of educational achievement in Slovenia. International analyses for the selected countries (high‐ and low‐achieving countries from the whole TIMSS population) confirm that this type of finding is culturally impartial as well as valid for the level of achievement both in math and in science.     

An analysis of frequency of hands-on experience and science achievement

A variance analysis of the relation between the amount of time students spent experiencing hands-on science and science achievement was performed. Data collected by the National Education Longitudinal Study of 1988 on a nationally representative sample of eighth-grade students were analyzed. Student achievement in science was measured by a cognitive test battery developed by the Educational Testing Service. Information regarding the frequency of hands-on experience was collected through a self-administered teacher questionnaire, which included a series of questions specific to the science curriculum. From the analysis it was concluded that significant differences existed across the hands-on frequency variable with respect to science achievement. Specifically, students who engaged in hands-on activities every day or once a week scored significantly higher on a standardized test of science achievement than students who engaged in hands-on activities once a month, less than once a month, or never. © 1996 John Wiley & Sons, Inc.     

Patterns of compensation of public and private school teachers

General impressions suggest that public school teachers are paid higher salaries than private school teachers. Indeed, the evidence is consistent with this general impression. But why the difference? Do public school teachers have better qualifications? Are private schools better places in which to work, and are they able to pay lower wages for comparable teachers? Do public and private schools even operate in the same market for teaching personnel? Are those individuals who seek employment in the private school sector from the same population as those seeking public school employment? What part does the ownership structure of the school play in the determination of teacher compensation? It is the purpose of this paper to provide some insights into these and related questions about the patterns of variation in compensation of public and private school teachers. Our findings reveal that public school teachers earn more than teachers in non-public schools. Teachers in parochial schools are the lowest paid, while teachers in non-sectarian private schools are the highest paid among non-public school teachers. There appear to be structural differences in the patterns of wage variation between the different sectors. Public school teachers possess greater quantities of those characteristics that are valued in the market than non-public school teachers. Non-public school teachers sacrifice between 10 and 40% of the public school teacher salary to work in the non-public sector (depending on the type of school within the non-public sector) and they are aware of their sacrifice. Organizational and ownership structure of the school also appears to make a difference in salaries, with profit-making schools being among the lowest paying, second only to parochial schools.

Learning environment,motivation, and achievement in high school science

In a study of the relationship between high school students' perceptions of their science learning environments and their motivation, learning strategies, and achievement, 377 students in 22 introductory science classrooms completed surveys in the fall and spring of their ninth‐grade year. Hierarchical linear regression was used to model the effects of variables at both the classroom and individual level simultaneously. High intraclass agreement (indicated by high parameter reliability) on all classroom environment measures indicated that students shared perceptions of the classroom learning environment. Controlling for other factors, shared perceptions that only the most able could succeed in science classrooms and that instruction was fast‐paced and focused on correct answers negatively predicted science achievement, as measured on a districtwide curriculum‐linked test. Shared perceptions that classrooms focused on understanding and independent thinking positively predicted students' self‐reported satisfaction with learning. Implications of these results for both teaching and research into classroom environments are discussed. © 2003 Wiley Periodicals, Inc. J Res Sci Teach 40: 347–368, 2003     

Relationship between affect and achievement in science and mathematics in Malaysia and Singapore

Background : The Trends in International Mathematics and Science Study (TIMSS) assesses the quality of the teaching and learning of science and mathematics among Grades 4 and 8 students across participating countries.

Purpose : This study explored the relationship between positive affect towards science and mathematics and achievement in science and mathematics among Malaysian and Singaporean Grade 8 students.

Sample : In total, 4466 Malaysia students and 4599 Singaporean students from Grade 8 who participated in TIMSS 2007 were involved in this study.

Design and method : Students’ achievement scores on eight items in the survey instrument that were reported in TIMSS 2007 were used as the dependent variable in the analysis. Students’ scores on four items in the TIMSS 2007 survey instrument pertaining to students’ affect towards science and mathematics together with students’ gender, language spoken at home and parental education were used as the independent variables.

Results : Positive affect towards science and mathematics indicated statistically significant predictive effects on achievement in the two subjects for both Malaysian and Singaporean Grade 8 students. There were statistically significant predictive effects on mathematics achievement for the students’ gender, language spoken at home and parental education for both Malaysian and Singaporean students, with R ² = 0.18 and 0.21, respectively. However, only parental education showed statistically significant predictive effects on science achievement for both countries. For Singapore, language spoken at home also demonstrated statistically significant predictive effects on science achievement, whereas gender did not. For Malaysia, neither gender nor language spoken at home had statistically significant predictive effects on science achievement.

Conclusions : It is important for educators to consider implementing self-concept enhancement intervention programmes by incorporating ‘affect’ components of academic self-concept in order to develop students’ talents and promote academic excellence in science and mathematics.     

Project design factors that affect student perceptions of the success of a science research project

Throughout the United States, various summer science programs for precollege students are conducted with an aim toward increasing the involvement of young people in science. Most of these programs are perceived as successful by teachers and scientists because they involve students in hands-on science activities, improve their scientific skills and confidence, and allow them the opportunity to use science to answer questions and solve problems. The work described here involves a detailed assessment of a summer National Science Foundation (NSF) Young Scholars Program, which was carried out over 2 summers. Student participants were entering 9th and 10th grade. The data used for this assessment included journals kept by teaching assistants, questionnaires administered to the participants and parents, and interviews with the participants. Analysis revealed that students perceived program success differently from teachers and program organizers. Their perception of the success of a program is directly related to whether or not their individual research project met its goals, regardless of other project activities. Designing projects that have a high likelihood of success from this perspective can be complex, but this work identified six variables that must be incorporated appropriately into the design of a project to ensure its success: (1) extent of project structure and who structures the project, faculty or student; (2) project relevance; (3) project flexibility; (4) project background research; (5) tangible results; and (6) project introduction.     

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.     

High school students presenting science: An interactional sociolinguistic analysis

Presenting science is an authentic activity of practicing scientists. Thus, effective communication of science is an important skill to nurture in high school students who are learning science. This study examines strategies employed by high school students as they make science presentations; it assesses students' conceptual understandings of particular science topics through their presentations and investigates gender differences. Data are derived from science presentation given by eight high school students, three females and five males who attended a summer science program. Data sources included videotaped presentations, ethnographic fieldnotes, interviews with presenters and members of the audience, and presenter notes and overheads. Presentations were transcribed and submitted to discourse analysis from an interactional sociolinguistic perspective. This article focuses on the methodology employed and how it helps inform the above research questions. The author argues that use of this methodology leads to findings that inform important social-communicative issues in the learning of science. Practical advice for teaching students to present science, implications for use of presentations to assess conceptual learning, and indications of some possible gender differences are discussed.     

Home and school contributions to science achievement in elementary schools in israel

This article reexamines the relative status of “school variables” versus “home variables” in explaining the variance in science achievement, based on data from Israeli elementary schools in 1984. The contribution of school variables was found to be “subject specific”—larger in subjects taught in school and less dependent on general ability, and “system specific”—larger in low socioeconomic schools and small in high socioeconomic schools.     

Trends and transitions in the institutional environment for public and private science

The last quarter-century bore witness to a sea change in academic involvement with commerce. Widespread university-based efforts to identify, manage, and market intellectual property (IP) have accompanied broad shifts in the relationship between academic and proprietary approaches to the dissemination and use of science and engineering research. Such transformations are indicators of institutional changes at work in the environment faced by universities. This paper draws upon a fifteen-year panel (1981–1995) of university-level data for 87 research-intensive US campuses in order to document trends and transitions in relationships among multiple indicators of academic and commercial engagement. The institutional environment for public and private science is volatile, shifting in fits and starts from a situation conducive to organizational learning through high volume patenting to a more challenging arrangement that links indiscriminate pursuit of IP with declines in both the volume and impact of academic science. The pattern and timing of these transitions may support an enduring system of stratification that offers increasing returns to first-movers while limiting the opportunities available to universities that are later entrants to the commercial realm. Unpacking the systematic effects of university research commercialization requires focused attention on the sources and trajectories of profound institutional change.     

An alternative instrument for private school competition

Empirical studies estimating the effect of private school competition on student outcomes commonly use the share of Catholics in the local population as an instrument for private school competition. I show that this is not a valid instrument since it is endogenous to private school competition and suggest using instead the local share of Catholics in the population in 1890 and its squared term. These instruments are very strong and are also exogenous to both student achievements and private school competition. I further show that using the current Catholic share as an instrument results in seriously flawed estimates of the effect of private school competition on math test scores and on educational attainment, to the extent that significant positive effects of private school competition on these outcome measures do not hold when the historical Catholic share in 1890 is used as an alternative instrument. The historical Catholic share in 1890 can also be applied to estimate the treatment effect of Catholic schools.     

The investigation of school effects on student achievement in science: A multilevel analysis of educational data

The Second International Science Study provides a large Australian data base for the purpose of secondary analyses. This data base consists of a large number of student and school level variables which were examined with reference to the students nested within the schools. Multilevel analysis involves the use of the hierarchical linear model to adequately compensate for variability between-schools, as well as within-schools. The role of the school organization and effects such as the average student ability and average social factors were found to substantially influence student achievement in science. These school effects were also found to influence boys and girls differently with respect to their science achievement as measured by the tests in this study. Specializations: large scale data analysis, gender differences, socioeconomic factors, epidemiology.
