Improving Science and Literacy Learning for English Language Learners: Evidence from a Pre-service Teacher Preparation Intervention

This paper present findings from a pre-service teacher development project that prepared novice teachers to promote English language and literacy development with inquiry-based science through a modified elementary science methods course and professional development for cooperating teachers. To study the project’s impact on student learning, we administered a pre and post assessment to students (N = 191) of nine first year elementary teachers (grades 3 through 6) who experienced the intervention and who taught a common science unit. Preliminary results indicate that (1) student learning improved across all categories (science concepts, writing, and vocabulary)—although the effect varied by category, and (2) English Language Learner (ELL) learning gains were on par with non-ELLs, with differences across proficiency levels for vocabulary gain scores. These results warrant further analyses to understand the extent to which the intervention improved teacher practice and student learning. This study confirms the findings of previous research that the integration of science language and literacy practices can improve ELL achievement in science concepts, writing and vocabulary. In addition, the study indicates that it is possible to begin to link the practices taught in pre-service teacher preparation to novice teacher practice and student learning outcomes.     

Relationship between Science Teaching Practices and Students’ Achievement in Singapore,Chinese Taipei,and the US: An Analysis Using TIMSS 2011 Data

The assumption that inquiry-based instruction is more effective in influencing student science achievement than traditional didactic teaching has been the driving force of science education reform in recent decades and in many countries. However, the empirical relationship between these two kinds of science teaching and student science performance is not soundly established, which is worth a careful examination. Framed through the theoretical perspectives of inquiry-based instruction and culturally relevant pedagogy, using a two-level hierarchical linear modeling (HLM) approach and simultaneous multiple regression, this study examines the above relationship using the Trends in International Mathematics and Science Study (TIMSS) 2011 8th grade dataset from Singapore, Chinese Taipei, and the US. The study found that for the low-performing students, none of the inquiry-based teaching practice items measured had a significant relationship with the science achievements at any performance levels of students in any country/region except for the case of two inquiry-based teaching practice items that were positively related to Chinese Taipei students’ achievements. No didactic teaching practice items were associated with the Singapore students’ science achievement, three of these practice items were found negatively related to Chinese Taipei students’ science achievement, and one traditional didactic teaching practice was negatively related to the science achievement of U.S. students. However, for medium- and high-performing students, none of these inquiry-based or traditional didactic science-teaching practices were found to be positive predictors of science performance in all three countries/regions. However, in the case of Chinese Taipei, one didactic teaching practice item was negatively related with the medium level performing students’ achievement and two didactic teaching practices were found to hinder high-performing students’ science achievements.     

The Impact of Design-Based STEM Integration Curricula on Student Achievement in Engineering,Science, and Mathematics

The new science education reform documents call for integration of engineering into K-12 science classes. Engineering design and practices are new to most science teachers, meaning that implementing effective engineering instruction is likely to be challenging. This quasi-experimental study explored the influence of teacher-developed, engineering design-based science curriculum units on learning and achievement among grade 4–8 students of different races, gender, special education status, and limited English proficiency (LEP) status. Treatment and control students (n = 4450) completed pretest and posttest assessments in science, engineering, and mathematics as well as a state-mandated mathematics test. Single-level regression results for science outcomes favored the treatment for one science assessment (physical science, heat transfer), but multilevel analyses showed no significant treatment effect. We also found that engineering integration had different effects across race and gender and that teacher gender can reduce or exacerbate the gap in engineering achievement for student subgroups depending on the outcome. Other teacher factors such as the quality of engineering-focused science units and engineering instruction were predictive of student achievement in engineering. Implications for practice are discussed.     

Moderation of the effects of scientific inquiry activities on low SES students’ PISA 2015 science achievement by school teacher support and disciplinary climate in science classroom across gender

Scientific inquiry activities are considered as productive science instruction to improve students’ science learning and achievement. Supportive teacher-student relationships and positive disciplinary climate in the classroom are also two important factors that could facilitate student learning. This study investigates whether the association between the inquiry-based science activities and student science achievement varies by teacher support and disciplinary climate in science classrooms, particularly when taking into consideration of student gender difference and socioeconomic status (SES). This study performed regression analyses using Beijing, Shanghai, Jiangsu, and Guangdong (B-S-J-G-China) students’ science performance and background survey data of 2015 Program for International Student Assessment (PISA). Results showed that disciplinary climate, rather than teacher support, could moderate the association between inquiry-based science activities and student science achievement for both genders. Implications for instruction and further research were discussed as well.     

Impact of professional development on teacher practice: Uncovering connections

An Inquiry Learning Partnership (ILP) for professional development (PD) was formed between a university, science centre, and two urban school districts to offer 4–6th grade teachers specific science content and pedagogical techniques intended to integrate inquiry-based instruction in elementary classrooms. From pre/post content exams, PD surveys, focus group, and assessment data, teachers increased their science content knowledge, reported implementing inquiry practices in their classrooms and their students experienced modest gains on 5th grade standardized science achievement exams. While some teachers were transferring knowledge/skills gained in professional development to their classrooms, others encountered barriers to implementing PD. These obstacles included limited resources, time constraints, mandated curriculum pacing, language learning, and classroom management issues. Strategies to mitigate these barriers in order to maximize the impact of professional development need to be a priority in professional development reform.     

A Review of Empirical Literature on Inquiry Professional Development: Alignment with Best Practices and a Critique of the Findings

This review brings together the literature on inquiry-based teaching and learning and science teacher professional development (PD). We present a targeted critical review of research focused specifically on the nature of PD programs purported to emphasize inquiry. Our review analyzes the features of each program and critiques the reported outcomes of each study. Findings from this review suggest a general alignment with recommended features of effective PD as outlined in the literature with a few notable exceptions, including: supporting teachers in developing inquiry-based lesson plans, providing authentic inquiry experiences, and focusing on science content for teachers. More importantly, our review reveals that no reported study has connected participation in inquiry-based PD with all the desired outcomes of teacher PD: enhanced teacher knowledge, change in beliefs and practice, and enhanced student achievement. Implications for future research on inquiry-based PD programs are discussed.     

Do Teachers’ Instructional Practices Moderate Equity in Mathematical and Scientific Literacy?: an Investigation of the PISA 2012 and 2015

Many efforts have been made to reach educational equity, especially to reduce mathematics and science achievement gaps by students’ socioeconomic status. Across countries, educators strive to reform traditional teacher-centered instructional approaches to more student-centered/inquiry-based instruction to improve equity in education. In this context, this study examines whether relationships between socioeconomic status and scientific or mathematical literacy are moderated by student-centered instruction. Ten countries covering a wide range of achievement levels as well as equity in education are selected for an international comparison. A linear regression analysis is applied to student achievement, equity, and frequency of student-centered instruction data from the PISA 2012 and PISA 2015. We find mixed results: As student-centered instruction is offered more frequently, the gap in mathematical and scientific literacy between low and high socioeconomic status is generally narrowed or maintained. In most countries, students’ mathematical and scientific literacy scores are expected to decrease across all socioeconomic status as student-centered instruction is given more frequently. The findings necessitate further scrutiny of how teachers implement student-centered instruction in various educational systems. This further research need to consider the complexity of implementation related to sociological and pedagogical aspects.     

The Impact of Professional Development on Elementary Teachers’ Strategies for Teaching Science with Diverse Student Groups in Urban Elementary Schools

This study examined elementary teachers’ instructional strategies for promoting scientific understanding and inquiry and supporting English language development with diverse student groups including English language learners. The study was part of a 5-year research and development project consisting of reform-based science curriculum units and teacher workshops aimed at providing effective science instruction to promote students’ science and literacy achievement in urban elementary schools. Data consisted of 213 post-observation interviews with third, fourth, and fifth grade teachers. The teachers reported using instructional strategies to promote scientific understanding, but generally did not employ more sophisticated inquiry-based strategies. They also reported using instructional strategies to support English language development. There were significant differences among grade levels and by years of teacher participation.     

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.     

Project Clarion: Three Years of Science Instruction in Title I Schools among K-Third Grade Students

The purpose of the study was to measure the effects of higher level, inquiry-based science curricula on students at primary level in Title I schools. Approximately 3,300 K-3 students from six schools were assigned to experimental or control classes (N?=?115 total) on a random basis according to class. Experimental students were exposed to concept-based science curriculum that emphasized ??deep learning?? though concept mastery and investigation, whereas control classes learned science from traditional school-based curricula. Two ability measures, the Bracken Basic Concept Scale-Revised (BBCS-R, Bracken 1998) and the Naglieri Nonverbal Intelligence Test (NNAT, Naglieri 1991), were used for baseline information. Additionally, a standardized measure of student achievement in science (the MAT-8 science subtest), a standardized measure of critical thinking, and a measure for observing teachers?? classroom behaviors were used to assess learning outcomes. Results indicated that all ability groups of students benefited from the science inquiry-based approach to learning that emphasized science concepts, and that there was a positive achievement effect for low socio-economic young children who were exposed to such a curriculum.     

Socioeconomic status and students' science self-efficacy

The present study ascertains the relationship between socioeconomic status (SES) and students' science self-efficacy using data involving 509,182 15-year-old students and 17,678 school principals in 69 countries/regions who participated in the Programme for International Student Assessment (PISA) 2015. Hierarchical linear modelling results show that, after controlling for science teachers' instructional practices (science class disciplinary climate, inquiry-based instruction, teachers' support, direct instruction, provision of feedback, instructional adaptation), school science resources and various student variables (gender, grade levels, type of school programme), SES was related to students' science self-efficacy in the majority of countries/regions (62–68 countries/regions, depending on the SES indicators used). Specifically, SES was related to students' science self-efficacy in a larger number of countries/regions when it was measured using home cultural resources, home educational resources or a composite indicator (economic, social and cultural status) than when it was measured using parental education levels or occupational status. In contrast, students' science self-efficacy was unrelated to the science teachers' instructional practices examined (except inquiry-based instruction) in most of the countries/regions. These results expand our understanding of students' science self-efficacy, as a type of learning motivation, from being a largely psychological attribute to one that is also influenced by social origins such as family SES. They imply that SES may have a larger influence on student achievement than we may have assumed if we include the indirect influence of SES on student achievement via students' self-efficacy.     

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.     

The Pedagogical Orientations of South African Physical Sciences Teachers Towards Inquiry or Direct Instructional Approaches

In recent years, inquiry-based science instruction has become widely advocated in science education standards in many countries and, hence, in teacher preparation programmes. Nevertheless, in practice, one finds a wide variety of science instructional approaches. In South Africa, as in many countries, there is also a great disparity in school demographic situations, which can also affect teaching practices. This study investigated the pedagogical orientations of in-service physical sciences teachers at a diversity of schools in South Africa. Assessment items in a Pedagogy of Science Teaching Test (POSTT) were used to identify teachers’ science teaching orientations, and reasons for pedagogical choices were probed in interviews. The findings reveal remarkable differences between the orientations of teachers at disadvantaged township schools and teachers at more privileged suburban schools. We found that teachers at township schools have a strong ‘active direct’ teaching orientation overall, involving direct exposition of the science followed by confirmatory practical work, while teachers at suburban schools exhibit a guided inquiry orientation, with concepts being developed via a guided exploration phase. The study identified contextual factors such as class size, availability of resources, teacher competence and confidence, time constraints, student ability, school culture and parents’ expectations as influencing the methods adopted by teachers. In view of the recent imperative for inquiry-based learning in the new South African curriculum, this study affirms the context specificity of curriculum implementation (Bybee 1993) and suggests situational factors beyond the curriculum mandate that need to be addressed to achieve successful inquiry-based classroom instruction in science.     

Differential Use of Elementary Science Kits

The use of kits in elementary science classes is a growing trend in some countries. Kits provide materials and inquiry lessons in a ready-to-teach format for teachers to use in their science instruction. This study examined elementary teachers' instructional strategies, classroom practices, and assessment types in relation to the frequency of science kit use. A total of 503 elementary teachers from an urban school district received professional development, implemented kits in their classrooms for a year, and then completed a survey about science kit use and teaching practices. Despite similarities in demographic characteristics (gender, ethnicity, certification/educational level), there were significant differences in teachers' use of inquiry-based teaching and assessment practices by kit use. Teachers who reported using kits the most often were significantly more likely to report that their students designed and implemented laboratory investigations as well recorded, represented, and analyzed data. In addition, the high kit users indicated that they were more likely to use student groups, require students to use evidence to support claims, and use alternative assessments of student work including portfolios, notebooks, and long-term projects than those teachers who used kits less frequently. Those teachers who reported using kits the least often were significantly more likely to report having students practice for standardized tests. The role of kits in promoting reform-based teaching practices is discussed.     

The Impact of High School Science Teachers’ Beliefs,Curricular Enactments and Experience on Student Learning During an Inquiry-based Urban Ecology Curriculum

Inquiry-based curricula are an essential tool for reforming science education yet the role of the teacher is often overlooked in terms of the impact of the curriculum on student achievement. Our research focuses on 22 teachers’ use of a year-long high school urban ecology curriculum and how teachers’ self-efficacy, instructional practices, curricular enactments and previous experience impacted student learning. Data sources included teacher belief surveys, teacher enactment surveys, a student multiple-choice assessment focused on defining and identifying science concepts and a student open-ended assessment focused on scientific inquiry. Results from the two hierarchical linear models indicate that there was significant variation between teachers in terms of student achievement. For the multiple-choice assessment, teachers who spent a larger percentage of time on group work and a smaller percentage of time lecturing had greater student learning. For the open-ended assessment, teachers who reported a higher frequency of students engaging in argument and sharing ideas had greater student learning while teachers who adapted the curriculum more had lower student learning. These results suggest the importance of supporting the active role of students in instruction, emphasising argumentation, and considering the types of adaptations teachers make to curriculum.     

Science Achievement for All: Improving Science Performance and Closing Achievement Gaps

This article addresses the serious and growing need to improve science instruction and science achievement for all students. We will describe the results of a 3-year study that transformed science instruction and student achievement at two high-poverty ethnically diverse public elementary schools in Texas. The school-wide intervention included purposeful planning, inquiry science instruction, and contextually rich academic science vocabulary development. In combination, these instructional practices rapidly improved student-science learning outcomes and narrowed achievement gaps across diverse student populations.     

A Randomized Study of a Literacy-Integrated Science Intervention for Low-Socio-economic Status Middle School Students: Findings from first-year implementation

This paper presents the findings from a randomized control trial study of reading/literacy-integrated science inquiry intervention after 1 year of implementation and the treatment effect on 5th-grade low-socio-economic African-American and Hispanic students’ achievement in science and English reading. A total of 94 treatment students and 194 comparison students from four randomized intermediate schools participated in the current project. The intervention consisted of ongoing professional development and specific instructional science lessons with inquiry-based learning, direct and explicit vocabulary instruction, and integration of reading and writing. Results suggested that (a) there was a significantly positive treatment effect as reflected in students' higher performance in district-wide curriculum-based tests of science and reading and standardized tests of science, reading, and English reading fluency; (b) males and females did not differ significantly from participating in science inquiry instruction; (c) African-American students had lower chance of sufficiently mastering the science concepts and achieving above the state standards when compared with Hispanic students across gender and condition, and (d) below-poverty African-American females are the most vulnerable group in science learning. Our study confirmed that even a modest amount of literacy integration in inquiry-based science instruction can promote students' science and reading achievement. Therefore, we call for more experimental research that focus on the quality of literacy-integrated science instruction from which middle grade students, particularly low-socio-economic status students, can benefit.     

Differentiated instruction in a data-based decision-making context

In this study, the relationship between differentiated instruction, as an element of data-based decision making, and student achievement was examined. Classroom observations (n = 144) were used to measure teachers’ differentiated instruction practices and to predict the mathematical achievement of 2nd- and 5th-grade students (n = 953). The analysis of classroom observation data was based on a combination of generalizability theory and item response theory, and student achievement effects were determined by means of multilevel analysis. No significant positive effects were found for differentiated instruction practices. Furthermore, findings showed that students in low-ability groups profited less from differentiated instruction than students in average or high-ability groups. Nevertheless, the findings, data collection, and data-analysis procedures of this study contribute to the study of classroom observation and the measurement of differentiated instruction.     

The Effect of a State Department of Education Teacher Mentor Initiative on Science Achievement

This study investigated the effectiveness of a southern state??s department of education program to improve science achievement through embedded professional development of science teachers in the lowest performing schools. The Science Mentor Program provided content and inquiry-based coaching by teacher leaders to science teachers in their own classrooms. The study analyzed the mean scale scores for the science portion of the state??s high school graduation test for the years 2004 through 2007 to determine whether schools receiving the intervention scored significantly higher than comparison schools receiving no intervention. The results showed that all schools achieved significant improvement of scale scores between 2004 and 2007, but there were no significant performance differences between intervention and comparison schools, nor were there any significant differences between various subgroups in intervention and comparison schools. However, one subgroup, economically disadvantaged (ED) students, from high-level intervention schools closed the achievement gap with ED students from no-intervention schools across the period of the study. The study provides important information to guide future research on and design of large-scale professional development programs to foster inquiry-based science.
