PERCEIVED SOCIAL RELATIONSHIPS AND SCIENCE LEARNING OUTCOMES FOR TAIWANESE EIGHTH GRADERS: STRUCTURAL EQUATION MODELING WITH A COMPLEX SAMPLING CONSIDERATION

Based on the Trends in International Mathematics and Science Study 2007 study and a follow-up national survey, data for 3,901 Taiwanese grade 8 students were analyzed using structural equation modeling to confirm a social-relation-based affection-driven model (SRAM). SRAM hypothesized relationships among students’ perceived social relationships in science class and affective and cognitive learning outcomes to be examined. Furthermore, the path coefficients of SRAM for high- and low-achieving subgroups were compared. Given the 2-stage stratified clustering design for sampling, jackknife replications were conducted to estimate the sampling errors for all coefficients in SRAM. Results suggested that both perceived teacher–student relationships (PTSR) and perceived peer relationships (PPR) exert significant positive effects on students’ self-confidence in learning science (SCS) and on their positive attitude toward science (PATS). These affective learning outcomes (SCS and PATS) were found to play a significant role in mediating the perceived social relationships (PTSR and PPR) and science achievement. Further results regarding the differences in SRAM model fit between high- and low-achieving students are discussed, as are the educational and methodological implications of this study.     

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.     

Nonscience majors learning science: A theoretical model of motivation

A theoretical model of nonscience majors' motivation to learn science was tested by surveying 369 students in a large‐enrollment college science course that satisfies a core curriculum requirement. Based on a social‐cognitive framework, motivation to learn science was conceptualized as having both cognitive and affective influences that foster science achievement. Structural equation modeling was used to examine the hypothesized relationships among the variables. The students' motivation, as measured by the Science Motivation Questionnaire (SMQ), had a strong direct influence on their achievement, as measured by their science grade point average. The students' motivation was influenced by their belief in the relevance of science to their careers. This belief was slightly stronger in women than men. Essays by the students and interviews with them provided insight into their motivation. The model suggests that instructors should strategically connect science concepts to the careers of nonscience majors through such means as case studies to increase motivation and achievement. © 2006 Wiley Periodicals, Inc.

Student conscientiousness,self‐regulated learning,and science achievement: An explorative field study

This explorative field study examined the mediating role of self‐regulated learning (SRL) in the relationship between the personality trait of conscientiousness, SRL, and science achievement in a sample of junior high school students. Over the course of an entire academic year, data on enacted SRL were collected each week for 52 eighth‐grade students in the context of an inquiry‐based ecology project. Data were also collected on personality traits, self‐reported study strategies, science project achievement, and grade point average. Findings show significant relationships between conscientiousness, SRL, and achievement. As hypothesized, conscientiousness was shown to significantly impact academic achievement in the inquiry‐based course, mediated by enacted SRL. © 2009 Wiley Periodicals, Inc.     

The influence of extracurricular activities on middle school students’ science learning in China

ABSTRACT

Informal science learning has been found to have effects on students’ science learning. Through the use of secondary data from a national assessment of 7410 middle school students in China, this study explores the relationship among five types of extracurricular science activities, learning interests, academic self-concept, and science achievement. Structural equation modelling was used to investigate the influence of students’ self-chosen and school-organised extracurricular activities on science achievement through mediating interests and the academic self-concept. Chi-square tests were used to determine whether there was an opportunity gap in the student’s engagement in extracurricular activities. The students’ volunteer and school-organised participation in extracurricular science activities had a positive and indirect influence on their science achievement through the mediating variables of their learning interests and academic self-concept. However, there were opportunity gaps between different groups of students in terms of school location, family background, and especially the mother’s education level. Students from urban areas with better-educated mothers or higher socioeconomic status are more likely to access diverse science-related extracurricular activities.     

A Cross-grade Comparison to Examine the Context Effect on the Relationships Among Family Resources,School Climate,Learning Participation,Science Attitude,and Science Achievement Based on TIMSS 2003 in Taiwan

This study aimed to examine whether the relationships among family resources, school climate, learning participation, science attitude, and science achievement are different between primary school students and junior high school students within one educational system. The subjects included 4,181 Grade 4 students and 5,074 Grade 8 students who participated in TIMSS 2003 in Taiwan. Using structural equation modeling, the results showed that family resources had significant positive effects for both groups of learners. Furthermore, a context effect for the structural relationship between school climate, learning participation, and science achievement was revealed. In the primary school context, Grade 4 students who perceived positive school climate participated in school activities more actively, and had better science performance. However, in the secondary school context, learning participation had a negative impact and led to lower science achievement. The implications about this result in relation to the characteristics of the two educational contexts in Taiwan were further discussed.     

Adjustment problems,self‐efficacy,and psychological distress among Chinese gifted students in Hong Kong

The relationships among adjustment problems, self‐efficacy, and psychological distress were investigated in a sample of 207 Chinese gifted students in Hong Kong. A mediation‐effect model specifying that adjustment problems had an effect on psychological distress mediated by self‐efficacy was hypothesized and tested using structural equation modeling procedures. For comparison, a direct‐effect model and a direct‐and‐mediation‐effect model were also fitted to the data. The results indicated that the direct‐and‐mediation‐effect model provided the best and a reasonably adequate fit, suggesting that the effects of adjustment problems on psychological distress could be direct, but more importantly the effects could also be mediated by self‐efficacy. Implications of the findings for enhancing the self‐efficacy of students to promote their psychological well‐being are discussed.     

Examining the mediating effect of science self-efficacy on the relationship between metavariables and science achievement

Current studies reveal that meta-level variables are very important in learning; however, little research has been devoted to the role of metaconceptual and meta-affective variables on student achievement. With the aim of filling this gap in the literature, the present study investigated the relationship between metavariables (metaconceptual awareness, metaconceptual regulation, affective awareness, and affective regulation) and science achievement with the mediating effect of science self-efficacy through structural equation modeling. A total of 576 eighth grade students participated in the study. Results indicated that science self-efficacy partially mediated the relationship that metaconceptual regulation and affective regulation have with science achievement. In other words, students who monitor and evaluate their existing conceptions and follow, control, and adapt their emotions are likely to have high science self-efficacy and then high science achievement. In addition, metaconceptual awareness, metaconceptual regulation, and affective regulation positively predicted science self-efficacy, which was itself a positive predictor of science achievement. The findings imply that metavariables are essential components of science achievement via self-efficacy.     

Testing a model of science process skills acquisition: An interaction with parents' education,preferred language,gender, science attitude,cognitive development,academic ability,and biology knowledge

Path analysis techniques were used to test a hypothesized structural model of direct and indirect causal effects of student variables on science process skills. The model was tested twice using data collected at the beginning and end of the school year from 67 9th- and 10th-grade biology students who lived in a rural Franco-American community in New England. Each student variable was found to have significant effects, accounting for approximately 80% of the variance in science process skills achievement. Academic ability, biology knowledge, and language preference had significant direct effects. There were significant mediated effects by cognitive development, parents' education, and attitude toward science in school. The variables of cognitive development and academic ability had the greatest total effects on science process skills. Implications for practitioners and researchers are discussed.     

A Structural Model of Prospective Science Teachers' Nature of Science Views

This study aims to establish a viable structural model of prospective science teachers' nature of science (NOS) views, which could be used as an analytical tool for understanding the complex relationships between prospective teachers' conceptions of NOS and factors possibly affecting their conceptions. In order to construct such a model, likely factors that might influence prospective teachers' NOS views were hypothesized. These included science process skills; attitudes toward science teaching; academic achievement in pedagogical and science courses; and social, religious, economic, political, aesthetic, and theoretical values. The hypothetical model was then developed and modified using structural equation modeling methodology. The final viable model indicates that attitudes toward science teaching, science process skills, academic achievement in pedagogical courses, religious values, and economic values explain NOS views with low predictive power.     

How object,situation and personality shape human attitude in learning: An activity perspective and a multilevel modeling approach

Based on Activity Theory, this article examines attitude formation in human learning as shaped by the experiences of individual learners with various learning objects in particular learning contexts. It hypothesizes that a learner's object-related perceptions, personality traits and situational perceptions may have different relationships with the general attitude toward all the learning objects involved and the specific attitude toward each. An empirical study was conducted to verify the hypothesized relationships with the method of multilevel structural equation modeling. The result suggests that object-related perceptions have stronger direct effects on the specific attitude, personality traits have weaker moderating effects on the general attitude, and situational perceptions have both moderating effects on the general attitude and mediated effects on the specific attitude through object-related perceptions.     

Motivational and affective determinants of self-regulatory strategy use in elementary school mathematics

The aim of the study was to investigate the relationships between elementary students’ reported use of self-regulatory strategies in mathematics and their motivational and affective determinants. Participants of the study were 344 fifth- and sixth-grade Greek students. Students were asked to complete self-reported measures regarding the strategies they use to self-regulate mathematics learning, their achievement goals in relation to mathematics, their self-efficacy concerning mathematics learning and achievement, the value they attribute to mathematics as a subject domain and their enjoyment of mathematics learning. Structural equation modelling confirmed a mediation model, that is, students’ mathematics self-efficacy, value beliefs about mathematics and enjoyment mediated the effects of achievement goals on reported strategy use. Results are discussed in terms of implications for elementary students’ self-regulated learning skills.     

Mediated Modeling in Science Education

Following two decades of corroboration, modeling theory is presented as a pedagogical theory that promotes mediated experiential learning of model-laden theory and inquiry in science education. Students develop experiential knowledge about physical realities through interplay between their own ideas about the physical world and particular patterns in this world. Under teacher mediation, they represent each pattern with a particular model that they develop through a five-phase learning cycle, following particular modeling schemata of well-defined dimensions and rules of engagement. Significantly greater student achievement has been increasingly demonstrated under mediated modeling than under conventional instruction of lecture and demonstration, especially in secondary school and university physics courses. The improved achievement is reflected in more meaningful understanding of course materials, better learning styles, higher success rates, lower attrition rates and narrower gaps between students of different backgrounds.

Resource Utilization Relative to Students’ Achievement in and Attitude Toward Science

Abstract

An examination of the relationships between the manner of utilization of human and material resources and students’ achievement in and attitude toward science was undertaken in this study. The results show that the frequency of use of laboratory resources had the highest positive correlation with achievement (.57) followed by the quality of use of laboratory resources (.51). Variables related to laboratory staff were not significantly related to achievement. For the attitude measure, the quality of use of laboratory resources had the highest correlation value (.42) followed by the frequency of use of laboratory resources (.39). When the nine resource utilization variables were regressed in a step-wise fashion on the dependent variables, only six made significant contributions to predictions of achievement and attitude. The relative contributions of the variables are reported in the paper.     

Relationships between attitude and achievement among college biology students

The purposes of this study were to (1) study changes in attitude toward science, school, and academic self among college biology students, and (2) to examine relationships between attitudes and achievement in an introductory college course in biology. The three attitude variables were assessed at the beginning and end of the study. Each of the three constructs was measured by the semantic differential and one additional instrument. One cognitive measure, biology achievement, was taken at the beginning and end of the study. This was accomplished by using the Nelson Biology Test. Another cognitive measure, grade in the course, as given by the instructor, was recorded at the end of the course. Normative data and correlation coefficients among pre- and postadministrations were calculated for each institution and the composite sample as well. An analysis of variance showed that while gains in scores on the Nelson Biology Test were significant beyond the 0.01 level of probability, changes in attitude scores were not. Correlations were calculated between the attitude and cognitive variables in this study. Relationships between academic self-concept and achievement in biology were the strongest. Data from this study show that while student cognitive behavior was changed during an introductory college biology course, selected attitudes either stayed the same or became slightly more negative. Affective as well as cognitive gains would appear to be desirable goals in college courses. As we learn more about relationships that exist between cognition and affect, science educators at all levels will become better equipped to improve learning in science.     

Effect of the Science Learning Environment on Science Achievement: A Comparison of 12 Countries from the IEA Second International Science Study

ABSTRACT

The International Association for the Evaluation of Educational Achievement (IEA) Second International Science Study (SISS) was conducted in 1984, resulting in a vast amount of educational data collected from 23 countries and educational systems. This research study reports on the analyses of 12 of those countries using multilevel modeling, investigating the relationships between the students’ reported perceptions of the science learning environment and their science achievement when controlling for student background variables. The three science learning environment scales which were collected in the SISS and analysed here were Student Participation, Teacher Directed Learning and Practical Work. Additionally, this research reports on the effect of these science learning environment scales on gender and socioeconomic differences in science achievement.

Opening up the black box: Teacher competence,instructional quality,and students’ learning progress

Existing research indicates inconsistent or at best weak predictive effects of teacher knowledge on student achievement. Data from Germany were used to examine the relation between teachers' content and pedagogical content knowledge, their perception, interpretation, and decision-making skills, the instructional quality implemented in class, and students' learning progression in mathematics. Rather than direct effects of teacher knowledge on students, we hypothesized an effect chain with multiple mediation processes while controlling for school type and student background. Multi-level modeling with 3496 students from 154 classrooms revealed a mediating role of teachers' skills and their instructional quality for the relation between teacher knowledge and students' learning progress. Effect sizes were medium to strong, and the model explained a large amount of variance. No direct effects of teachers’ knowledge on student progress were found. We discuss our findings with respect to the teacher-competence-as-a-continuum model and with respect to future research.     

Students’ approaches to learning in problem-based learning: Taking into account professional behavior in the tutorial groups,self-study time,and different assessment aspects

Problem-based learning (PBL) represents a major development in higher educational practice and is believed to promote deep learning in students. However, empirical findings on the promotion of deep learning in PBL remain unclear. The aim of the present study is to investigate the relationships between students’ approaches to learning (SAL) and academic achievement in a PBL environment, taking into account the role of self-study time and students’ professional behavior in the PBL tutorial groups. In addition, different knowledge categories that determine achievement (i.e., understanding of concepts, understanding of the principles that link concepts, and the linking of concepts and principles to conditions and procedures for application) were taken into account. A hypothesized structural equation model including these variables was tested. Results showed that the PBL students in this study reported more use of a surface compared to a deep approach to learning. The hypothesized model demonstrated an excellent fit of the model with the data. The relationship between SAL and academic achievement was mediated by self-study time and professional behavior. These findings imply that self-study time and professional behavior are crucial variables to take into account when studying SAL.
