An investigation of teacher impact on student inquiry science performance using a hierarchical linear model

Teachers play a central role in inquiry science classrooms. In this study, we investigate how seven teacher variables (i.e., gender, experience, perceived importance of inquiry and traditional teaching, workshop attendance, partner teacher, use of technology) affect student knowledge integration understanding of science topics drawing on previous research. Using a two‐level hierarchical linear model, we analyze year‐end knowledge integration performance of 4,513 students taught by 40 teachers across five states. Results indicate that students of teachers who value inquiry teaching strategies have significantly higher levels of knowledge integration understanding than those of teachers who believe in traditional teaching methods. In addition, workshop attendance and having a partner teacher teaching the same unit in the same school also have a positive impact on students' knowledge integration levels. The results underscore the importance of professional development and collegial support in enhancing student success in inquiry science. © 2009 Wiley Periodicals, Inc.

Investigating the relationship between instructional practices and science achievement in an inquiry-based learning environment

ABSTRACT

This study investigates the discrete effects of inquiry-based instructional practices that described the PISA 2015 construct ‘inquiry-based instruction’ and how each practice, and the frequency of each practice, is related to science achievement across 69 countries. The data for this study were drawn from the PISA 2015 database and analysed using hierarchical linear modelling (HLM). HLMs were estimated to test the contribution of each item to students’ science achievement scores. Some inquiry practices demonstrated a significant, linear, positive relationship to science achievement (particularly items involving contextualising science learning). Two of the negatively associated items (explaining their ideas and doing experiments) were found to have a curvilinear relationship to science achievement. All nine items were dummy coded by the reported frequency of use and an optimum frequency was determined using the categorical model and by calculating the inflection point of the curvilinear associations in the previous model e.g. students that carry out experiments in the lab in some lessons have higher achievement scores than students who perform experiments in all lessons. These findings, accompanied by detailed analyses of the items and their relationships to science outcomes, give stakeholders clear guidance regarding the effective use of inquiry-based approaches in the classroom.     

comparison of three growth modeling techniques in the multilevel analysis of longitudinal academic achievement scores: Latent growth modeling, hierarchical linear modeling, and longitudinal profile analysis via multidimensional scaling

This study introduces three growth modeling techniques: latent growth modeling (LGM), hierarchical linear modeling (HLM), and longitudinal profile analysis via multidimensional scaling (LPAMS). It compares the multilevel growth parameter estimates and potential predictor effects obtained using LGM, HLM, and LPAMS. The purpose of this multilevel growth analysis is to alert applied researchers to selected analytical issues that are required for consideration in decisions to apply one of these three approaches to longitudinal academic achievement studies. The results indicated that there were no significant distinctions on either mean growth parameter estimates or on the effects of potential predictors to growth factors at both the student and school levels. However, the study also produced equivocal findings on the statistical testing of variance and covariance growth parameter estimates. Other practical issues pertaining to the three growth modeling methods are also discussed.     

Goals,data use,and instruction: the effect of a teacher professional development program on reading achievement

In this paper, we investigated whether student reading comprehension could be improved with help of a teacher Professional Development (PD) program targeting goals, data use, and instruction. The effect of this PD program on 2nd- and 3rd-grade student achievement was examined using a pretest-posttest control group design. Applying propensity score matching, 35 groups in the experimental condition were matched to 35 control groups. Students in the experimental condition (n = 420) scored significantly higher on a standardized assessment than the control condition (n = 399), the effect size being d = .37. No differential effects of the PD program were found in relation to initial reading performance or grade. Different model specifications yielded similar albeit smaller effect sizes (d = .29 and d = .30). At the end of the program, students in the experimental condition were more than half a year ahead of students in the control condition.     

Perceived teacher affective support in relation to emotional and motivational variables in elementary school science classrooms in Turkey

Background: In recent research, affective learning environments and affective support have been receiving increasing attention for their roles in stimulating students’ learning outcomes. Despite its raising importance, little is known about affective support in educational contexts in developing countries. Moreover, international student assessment programmes (e.g. PISA and TIMSS) reveal poor science proficiency of students in most of those countries, which provokes the question of how to make positive changes in students’ perspectives and attitudes in science.

Purpose: In the current study, the purpose was to investigate the relations among perceived teacher affective support (PTAS), academic emotions (academic enjoyment, academic anxiety, and academic hopelessness), academic self-efficacy and behavioural engagement in elementary school science classrooms in Turkey.

Sample: A total of 633 fourth- and fifth-grade students in eight elementary schools in Istanbul, Turkey were participated in the study.

Design and methods: A self-report questionnaire was administered to participating students. The data were analysed using structural equation modelling.

Results: Findings showed that PTAS was both directly and indirectly related to the given variables. PTAS was found to be significantly positively associated with students’ academic enjoyment, academic self-efficacy and behavioural engagement and significantly negatively related to their academic anxiety and academic hopelessness in science classrooms. An important finding is that the total effect of PTAS on behavioural engagement, a factor strongly associated with academic success in all disciplines, was as strong as the effect of students’ perceived academic self-efficacy beliefs in science.

Conclusions: Findings suggest that PTAS may help promoting positive emotions and motivation among students in science classrooms, eventually leading to more desirable attitudes and achievement outcomes in science. Teacher affective support deserves greater recognition from researchers, educational policy-makers, administrators and teachers to build better learning conditions for all students.     

The influence of early science experience in kindergarten on children's immediate and later science achievement: Evidence from the early childhood longitudinal study

This study explores the impacts of selected early science experiences in kindergarten (frequency and duration of teachers' teaching of science, availability of sand/water table and science areas, and children's participation in cooking and science equipment activities) on children's science achievement in kindergarten and third grade using data for 8,642 children from the Early Childhood Longitudinal Study‐Kindergarten cohort (ECLS‐K). A theoretical model that depicts the relationships between the study variables was developed and tested using structural equation modeling. Results demonstrated that availability of science materials in kindergarten classrooms facilitated teachers' teaching of science and children's participation in science activities. Likewise, the frequency and the duration of kindergarten science teaching was a significant predictor of children's science activities but not of the children's end of kindergarten science achievement scores. Children's engagement with science activities that involved using science equipment also was not a significant predictor of their end of kindergarten science achievement. However, children's participation in cooking activities was. Children's prior knowledge, motivation, socio‐economic status, and gender were all statistically significant predictors of their science achievement at the end of kindergarten and end of third grade. Results of this study indicate that early science experiences provided in kindergarten are not strong predictors of children's immediate and later science achievement. Findings of the study suggest that the limited time and nature of science instruction might be related to the limited effect of the science experiences. Implications for teacher education programs and educational policy development are discussed. © 2010 Wiley Periodicals, Inc. J Res Sci Teach 48: 217–235, 2011     

Science self-beliefs and science achievement of adolescents in Gulf Cooperation Council countries

This study explored the predictive effects of science self-beliefs on science achievement for 24,680 13-year-old students from Gulf Cooperation Council member countries – Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates – who participated in the Trends in International Mathematics and Science Study (TIMSS) 2007. The performance of adolescent students in Qatar and Saudi Arabia on the TIMSS 2007 science assessment was significantly below the TIMSS scale average. Adolescent students’ science beliefs had both positive and negative predictive effects on science achievement across the Gulf Cooperation Council member countries.     

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.     

The role of perceived classroom goal structures,self-efficacy,and engagement in student science achievement

Background: Numerous studies have been conducted to investigate the factors related to science achievement. In these studies, the classroom goal structure perceptions, engagement, and self-efficacy of the students have emerged as important factors to be examined in relation to students’ science achievement.

Purpose: This study examines the relationships between classroom goal structure perception variables (motivating tasks, autonomy support, and mastery evaluation), engagement (behavioral, emotional, cognitive, and agentic engagement), self-efficacy, and science achievement.

Sample: The study participants included 744 seventh-grade students from 9 public schools in two districts of Gaziantep in Turkey.

Design and methods: Data were collected through the administration of four instruments: Survey of Classroom Goals Structures, Engagement Questionnaire, Motivated Strategies for Learning Questionnaire, and Science Achievement Test. The obtained data were subjected to path analysis to test the proposed model.

Results: Students’ perceptions of classroom goal structures (i.e. motivating tasks, autonomy support, and mastery evaluation) were found to be significant predictors of their self-efficacy. Autonomy support was observed to be positively linked to all aspects of engagement, while motivating tasks were found to be related only to cognitive engagement. In addition, mastery evaluation was shown to be positively linked to engagement variables, except for cognitive engagement, and self-efficacy and engagement (i.e. behavioral, emotional, and cognitive engagement) were observed to be significant predictors of science achievement. Finally, results revealed reciprocal relations among engagement variables, except for agentic engagement.

Conclusions: Students who perceive mastery goal structures tend to show higher levels of engagement and self-efficacy in science classes. The study found that students who have high self-efficacy and who are behaviorally, emotionally, and cognitively engaged are more successful in science classes. Accordingly, it is recommended that science teachers utilize inquiry-based and hands-on science activities in science classes and focus on the personal improvement of the students. Furthermore, it is also recommended that they provide students with opportunities to make their own choices and decisions and to control their own actions in science classes.     

Outside school time: an examination of science achievement and non-cognitive characteristics of 15-year olds in several countries

Elementary and secondary students spend more hours outside of class than in formal school and thus have more time for interaction with everyday science. However, evidence from a large international survey, Program of International Student Assessment (PISA) (OECD 2012), found a negative relationship between number of hours attending after-school science and science assessment scores in many countries, raising questions about why. The secondary analysis of the 2006, 2009, and 2012 PISA surveys found that in most Western countries the longer students attended after-school science programs (in a typical week), the lower their PISA standardized science test score, but the higher their positive attitudes toward future science careers, interest in science, and self-confidence in science. Several potential hypotheses for this relationship are examined and rejected. Further analysis of a causal relationship between frequent attendance in after-school programs and student achievement and attitudes should clearly identify the content of the program so that the analysis could distinguish experiences closely related to regular school curricula from the informal science activities that are not. A new analysis also should include carefully designed longitudinal surveys to test the effectiveness of informal experiences on later life choices in career and study.     

Differential effects of three professional development models on teacher knowledge and student achievement in elementary science

To identify links among professional development, teacher knowledge, practice, and student achievement, researchers have called for study designs that allow causal inferences and that examine relationships among features of interventions and multiple outcomes. In a randomized experiment implemented in six states with over 270 elementary teachers and 7,000 students, this project compared three related but systematically varied teacher interventions—Teaching Cases, Looking at Student Work, and Metacognitive Analysis—along with no‐treatment controls. The three courses contained identical science content components, but differed in the ways they incorporated analysis of learner thinking and of teaching, making it possible to measure effects of these features on teacher and student outcomes. Interventions were delivered by staff developers trained to lead the teacher courses in their regions. Each course improved teachers' and students' scores on selected‐response science tests well beyond those of controls, and effects were maintained a year later. Student achievement also improved significantly for English language learners in both the study year and follow‐up, and treatment effects did not differ based on sex or race/ethnicity. However, only Teaching Cases and Looking at Student Work courses improved the accuracy and completeness of students' written justifications of test answers in the follow‐up, and only Teaching Cases had sustained effects on teachers' written justifications. Thus, the content component in common across the three courses had powerful effects on teachers' and students' ability to choose correct test answers, but their ability to explain why answers were correct only improved when the professional development incorporated analysis of student conceptual understandings and implications for instruction; metacognitive analysis of teachers' own learning did not improve student justifications either year. Findings suggest investing in professional development that integrates content learning with analysis of student learning and teaching rather than advanced content or teacher metacognition alone. © 2012 Wiley Periodicals, Inc.

Investigation of the science achievement models for low and high achieving schools and gender differences in Turkey

A science achievement model was separately investigated for students in low and high achieving schools (LAS and HAS) in Turkey. Then, gender differences based on variables that significantly contributed to each achievement model were investigated. The student-level variables that were under investigation for multiple regression analyses include attitudes toward science, epistemological beliefs, metacognition, views on science teaching, and socioeconomic status (SES). The science achievement scores of students on a nationwide exam were used to measure science achievement. Both for LAS and HAS, two schools were selected. Results were reported for 241 and 320 students in LAS and HAS, respectively. According to the results, self-concept in science, knowledge of cognition, SES, importance of science, gradual learning, and views on lab work significantly contributed to the science achievement model in LAS. On the other hand, self-concept in science, SES, gradual learning, studying, and learning science in school significantly contributed to the science achievement model in HAS. Results also revealed that girls outperformed boys on knowledge of cognition and importance of science in LAS. Moreover, girls scored higher than boys on gradual learning and studying in HAS. According to these findings, implications for science education were discussed.     

Self‐concept and science achievement: Investigating a reciprocal relation model across the gender classification in a crosscultural context

Science achievement and self‐concept are articulated in this study to examine a model of reciprocal relationship during a crosscultural transition. Trend data have been gathered to assess changes of the perceived English importance before and after Hong Kong's sovereignty handover from Britain to China. The data analyses were conducted four times across dimensions of gender and timing over which the political transition took place. Besides small gender differences in the statistical results, weak but significant reciprocal relationships have been found between science achievement and self‐concept. In line with a policy of switching the medium of instruction from English to Chinese in most secondary schools, interpretation of different path coefficients obliges incorporation of cross‐cultural understanding in science education. © 2006 Wiley Periodicals, Inc.

Socio‐economic background,parental involvement and teacher perceptions of these in relation to pupil achievement

Parental involvement and teacher perceptions of parental involvement in the education of children were studied in relation to level of parental education and pupil achievement. A questionnaire was administered to 218 parents and 60 teachers. Correlational analyses and paired‐sample analyses showed teacher perceptions to be weakly related to parental reports of their own involvement and to operate at a different level. Regression analyses and analyses of variance showed teacher perceptions of parental involvement to affect pupil achievement more strongly than parental reports. The results suggest that teacher perceptions of parents may be stereotyped and that such stereotypes can clearly affect academic results.     

Investigating the impacts of targeted professional development around models and modeling on teachers' instructional practice and student learning

Developing understanding of models and proficiency with modeling practice is challenging for both teachers and students. This 2‐year study first investigated existing instructional strategies employed by teachers while teaching Earth and Space Science with dynamic physical models. Summer professional development introduced a conceptual framework, based on analogical reasoning, to help students strengthen and deepen the connections they make between a model and its real‐world referent. The framework draws explicit attention to correspondences and non‐correspondences between model and referent, an often overlooked component of modeling practice which underpins the ability to evaluate and thus improve a model. Teachers were guided to reflect on their own instructional use of models and to plan for integrating specific instructional strategies around models into their Year 2 practice. Classroom observation data reveal that from Years 1 to 2, teachers shifted from a more didactic approach in which they used physical models primarily as tools for demonstration toward more student engagement with models as problem‐solving tools. On an assessment measuring their students' ability to reason with and about models, pre‐post learning gains were higher in Year 2 than Year 1 across students at all ability levels. Together, these findings present evidence that teachers can learn to guide their students toward using physical models in ways that approximate key aspects of how scientists use runnable models, as envisioned by the Developing and Using Models practice of the Next Generation Science Standards.     

Changes in self-esteem across the first year in college: the role of achievement goals

This longitudinal study examined the effects of achievement goals on the growth trajectories of self-esteem during the first-year at a comprehensive public university. College freshmen (N?=?311) were followed for one academic year with three time points. Between-individual differences and within-individual change in achievement goals were distinguished and used as predictors for the growth trajectories of self-esteem. A growth curve analysis revealed that initially high mastery goals and subsequent increases in mastery goals were related to high self-esteem while initially high performance-avoidance goals were related to low self-esteem. The initial levels of performance-approach goals were not related to self-esteem but subsequent increases in performance-approach goals were associated with low self-esteem. Theoretical and practical implications are discussed.     

Students and school characteristics related to elementary school students' views of the nature of science

The purpose of this study is to investigate student- and school-level factors that help to explain the difference in the nature of science (NOS) views. Overall, the design of this study is correlational. The sample consisted of 3062 students enrolled in the sixth, seventh, and eighth grades of elementary schools in Turkey. A hierarchical linear modelling was selected as a modelling technique. This study has established the importance of the student's socioeconomic background, learning approaches undertaken, self-efficacy, and motivational goals in the formation of their NOS views. The findings reveal that quality of both the physical infrastructure of schools and the educational resources in schools, parent educational levels, student achievement, self-efficacy, experience of meaningful learning, and learning goal orientation are positively related to different dimensions of student NOS views. Additionally, performance goal orientation and rote learning approaches have a negative relationship with different dimensions of student NOS views.
