A meta-analysis of the effects of various science teaching strategies on achievement

This study is a meta-analysis of the question “What are the effects on achievement of different teaching techniques?” Twelve categories of teaching techniques were specified. Among these are questioning, wait-time, testing, focusing, manipulative, presentation approach, inquiry or discovery, audio-visual, and teacher direction. A coding form was then developed to allow for the uniform examination and recording of 76 variables from each study. One or more effect sizes were calculated and coded for each study. Over 300 microfilmed dissertations covering the past 30 years were examined. Some 2000 ERIC science abstracts were reviewed and suitable studies obtained. Finally, journal articles were reviewed. A total of 400 effect sizes representing 160 studies were produced. The main effect size overall was 0.34. Thus, for all samples considered the experimental science teaching techniques on the average resulted in one-third of a standard deviation improvement over traditional techniques. Mean effect sizes also were calculated for each technique. More than 20 other variables such as class size, community type, and science subject area were cross-tabulated with effect size.     

Teacher perceptions and individual differences: How they influence rural teachers’ motivating strategies

This study examined the influence of high school teachers’ perceptions and individual difference characteristics on teachers’ use of motivating strategies in their classrooms. Participants were 75 teachers in 19 rural, public high schools. A mixed method approach was used. Quantitative measures included demographics, individual differences, perceptions, and motivating strategies, analyzed as correlations and regressions. Qualitative measures included generative self-report of motivating a student, and semi-structured interviews, which were open coded and then axial coded to identify themes and issues. Peer-related environment stood out among teacher perceptions predicting student motivation. Teacher support and efficacy predicted motivating strategies, but teacher perceptions of student goals and causes of lack of motivation did not. Teachers admit that they lack knowledge and efficacy for motivating students. Findings can inform teacher education, professional development, and administrative support for teaching effectiveness.     

Students' Perceptions of Interpersonal Aspects of the Learning Environment

This study examined variables associated with differences in students' perceptions of interpersonal teacher behavior. The perceptions of 3023 students and 74 teachers in 168 classes in seven secondary schools were used in the analyses. Investigating variance at the student, class, teacher and school levels revealed that several variables are significantly related to students' perceptions: student and teacher gender, student and teacher ethnic background, student age and grade, class size, grade level, subject taught and teacher experience. There were interaction effects between some variables, such as student ethnicity and student gender, as well as student and teacher gender. While significant, the amount of variance explained by these was low (around 10%). The outcomes generally confirmed earlier research, although some new effects were found. Perhaps the main result of the study was its verification of the complex and interactive nature of students' perceptions of the learning environment and researchers' understanding of it.     

Student Authoritarianism and Teacher Authoritarianism as Factors in the Determination of Student Performance and Attitudes

Recent investigations designed to elucidate the teacher behaviors which are facilitative of positive student attitudes and increased student performance have presented inconsistent results. It is hypothesized that the inconsistency between studies may be due to an interaction between teacher characteristics and student characteristics in the determination of the dependent variables involved. To test this hypothesis, teachers and students in a West Coast high school were administered a revised version of the California F-Scale (a measure of authoritarianism). High- and Low-F groups of both teachers and students were selected, and students’ grades and attitudes toward their teachers were observed. It was found that High-F students exposed to Low-F teachers showed particularly low attitudes toward their teachers and particularly low grades. Data for other combinations of student and teacher characteristics were essentially equivalent.     

EFFECT OF CLASS SIZE,GRADES GIVEN,AND ACADEMIC FIELD ON STUDENT OPINION OF INSTRUCTION

This study reviewed the effect of class size, grades given, and academic field on student opinion of instruction. Data analysis showed that there were no significant correlations between variables of the three groups: (a) class size and student opinion of instruction; (b) grades given and student opinion of instruction, and (c) college and national academic field rankings and student opinion of instruction. These results leave teacher effectiveness as the most likely variable to explain ratings of student opinion of instruction.     

Exploring how teacher-related factors relate to student achievement in learning advanced algebra in technology-enhanced classrooms

In this study, we examine the relationship between contextual variables related to teachers and student performance in Advanced Algebra classrooms in the USA. The data were gathered from a cluster-randomized study on the effects of SimCalc MathWorlds^®, a curricular and technological intervention as a replacement for Algebra 2 curriculum, on student learning of Algebra 2 content. Conditional measures (teacher background characteristics) and instructional measures (self-reported instructional preferences, stances, and classroom practices) were subjected to a variety of empirical analyses to discern their relationship to student learning. Researchers examined both the overall effect of teacher contextual variables on student learning and the specific effect of SimCalc on both teacher instructional measures and student performance. There is evidence to support that teachers who use the SimCalc curriculum value classroom communication, deep understanding of math concepts, and support for both routine and non-routine problems.     

Teacher and child variables as predictors of academic engagement among low‐income African American children

A causal model for understanding the complex interplay between student‐reported teacher behaviors, student self‐systems, and student engagement was tested. One hundred seventeen African American students in grades 1 through 12 completed a comprehensive questionnaire regarding teacher context, self, and engagement variables. A series of hierarchical regression analyses were conducted to test the hypothesized mediation models and to construct a path model. Most hypotheses were supported. Student self‐system variables (perceived competency and autonomy) mediated relations between teacher context (structure and autonomy support), and engagement. Contrary to predictions, however, teacher involvement exerted a strong and direct effect on student engagement even when controlling for grade level and self‐system variables. Given existing research showing that African American students are at risk for low teacher involvement and that engagement is critical for academic success, research and intervention strategies are urgently needed to promote teacher involvement with these students. © 2002 Wiley Periodicals, Inc.     

Bias hypotheses under scrutiny: investigating the validity of student assessment of university teaching by means of external observer ratings

To advance the discussion on the validity of student evaluations of university teaching, student ratings of two teaching dimensions – student involvement and rapport – were compared with corresponding observer ratings. Seven potential bias variables were tested with regard to their impact on the students’ teaching assessment: three teacher characteristics (first impression, enthusiasm, humour) and four student characteristics (prior interest, expected grades, study experience, class attendance). Bias was defined as an impediment of the students’ assessment of teaching on course level. By means of bivariate correlations with course averages and two-level latent moderated structural equations, data of 1,716 students in 80 courses were analysed. Results showed that all three teacher characteristics were genuinely connected to rapport, and even explained variance of the student-rated variable when controlling for observer-rated rapport. The assessment of student involvement was not modified by the teacher characteristics except for teacher enthusiasm, which affected the student evaluation when controlling for observed involvement and, moreover, moderated the relation between the observed and the student-rated variable. For the examined student characteristics, no biasing effects were found – neither on rapport nor on student involvement.     

Meeting the highly qualified teachers challenge

The moulding of the future of a nation depends on the teachers and the education they provide in schools. Research evidence from the US. National Assessment of Educational Progress (NAEP) confirms this to be the case. Quantitative analysis of data indicates that measures associated with pre-service teacher preparation are by far the strongest correlates of student achievement (Darling-Hammond 2000). The research report of Wilson, Floden, and Ferrini-Mundy (2001) also suggests a strong relationship between teacher preparation and teacher effectiveness. Other research studies similarly indicate that differences in teacher quality are the most crucial for student achievement when compared with variables such as class size, streaming, or the amount of homework (Anderson & Helms 2001; Mendro 1998; Powell & Anderson 2002; Rivkin, Hanushek & Kain 2001; Saunders & Horn 1994; Strong & Tucker 2000) as possible contributory factors. In the pursuit of improved student achievement, we therefore need to examine seriously the role of teacher variables, ranging from teacher qualifications and their subject matter knowledge, to what motivates them to take up teaching as a career and as a consequence, how they teach in classrooms.     

School quality and learning gains in rural Guatemala

I use unusually detailed data on schools, teachers and classrooms to explain student achievement growth in rural Guatemala. Several variables that have received little attention in previous studies – including the number of school days, teacher content knowledge and pedagogical methods – are robust predictors of achievement. A series of decompositions by student ethnicity and type of school shed some additional light on important questions in the Guatemalan context, and beyond. The large indigenous test score gap is not explained by differences in an extensive list of observable features of schools. The large effect for community characteristics suggests peer group effects or more general institutional differences related to services or labor markets. PRONADE community schools are associated with moderate gains vis-à-vis public schools in areas related to utilization of capacity, such as days worked. But these gains are largely offset by lower teacher capacity, which highlights the challenge of improving school quality in poor, rural areas.     

Schools as Learning Organisations - Effects on Teacher Leadership and Student Outcomes

This article examines the nature of organisational learning and the leadership practices and processes that foster organisational learning and, more importantly, the impact of these variables on teacher leadership. A path model is used to test these school variables as well as school characteristics such as availability of resources and community focus against the impact of SES and school size on students' views of teachers' work in the classroom and student outcomes such as attendance, and participation in and engagement with school. The importance of reconceptualising schools as learning organisations to promote successful school change is discussed.     

Child level correlates of teacher–student relationships: An examination of demographic characteristics,academic orientations,and behavioral orientations

The purpose of this investigation was to examine associations between different child characteristics and conflict, closeness, and dependency within teacher–student relationships. The participants were primarily students of color from lower socioeconomic status backgrounds in a large urban school district. The strength of associations between student demographic variables, academic orientations, behavioral orientations, and aspects of teacher–student relationships was examined. Findings indicated that these variables accounted for a significant amount of variance in teacher ratings of conflict and dependency in teacher–student relationships. Externalizing and internalizing symptomology demonstrated the strongest associations with the conflict and dependency relationship constructs. Preliminary implications of these findings for teachers and school psychologists are explored. © 2004 Wiley Periodicals, Inc. Psychol Schs 41: 751–762, 2004.     

Teacher Professional Development and Student Reading Achievement: A Meta-Analytic Review of the Effects

Abstract

Research-based instruction is necessary to support students’ reading development, and professional development (PD) is a critical avenue to ensuring high-quality instructional practices. To date, there has been no comprehensive review focused on the effects of teacher PD on student reading achievement. As such, the purpose of the present meta-analysis was to examine the impact of teacher PD on reading outcomes for students in kindergarten through 8th grade. A secondary aim was to determine whether study, program, or participant characteristics were potential moderators of these effects. A comprehensive search of published and unpublished research between 1975 and 2017 resulted in 28 studies that met prescribed criteria. Results indicate that teacher PD has a moderate and significant, positive average effect on reading achievement. However, moderator analyses did not explain the variance in the effects of PD on student outcomes. Primarily, studies represented typically-developing students in the elementary grades, with only three studies including middle school students and four studies including reading outcomes of students with or at-risk for reading disabilities. Recommendations for improved study designs that allow for more in-depth investigation of the characteristics of effective PD and mechanisms of change in student outcomes are discussed.     

Two teacher quality measures and the role of context: evidence from Chile

This research examines empirically the relationship between two measures of teacher quality: one based on professional standards and a second one using teacher value-added estimates. It also studies the extent to which teacher observable characteristics, such as teacher training variables, are associated to better performance on either of these measures and whether any of these two assessments is able to effectively measure teacher quality isolated from the effect of the context where teachers work. Context in this article is defined as any variable that is not under the direct control of the teacher but plays an important role on student learning and we believe is captured by school and municipal variables. The study uses hierarchical linear models and information from national and standardized assessments from Chile, specifically from the municipal education sector. Results show a small correlation between the two measures of teacher quality, in the lower end of results from previous studies conducted in the USA, and suggest that there is only a limited relationship between both measures of teacher quality. Teacher initial education type and professional development were statistically associated only to the standard-based measure of teacher quality. Context (both the school and municipal levels) plays an important role in the teacher effect measure, and in the standard-based measures, therefore, we conclude that neither of these measures are context-free. We expect that these results will contribute to the discussion about how to best measure teacher quality and how to evaluate teacher performance both in Chile and other parts of the world.     

The role of goal orientations and goal structures in explaining classroom social and affective characteristics

Examining motivational variables may prove to be particularly fruitful towards our understanding of classroom processes, student behaviors and school outcomes. The present study examined the role of personal and contextual goals (goals and goal structures) towards explaining social relationships (peer, teacher–student and home–school). 1493 fifth and sixth grade primary school students (10 to 12 years of age) from different areas of Greece formed a representative sample. Questionnaires were administered assessing students' goal orientations, goal structures and classroom relationships. The data were analyzed using latent variable modeling. Mastery goal structures had significant effects on positive school relationships such as student relations, teacher–student relations, peer inclusion, and peer conflict (the latter two reversely coded). Performance goal structures exerted negative or null effects on the same processes, demonstrating their negative propensities. In addition, the effects of mastery goal structures were partially mediated by the effects of personal mastery goals with regard to teacher–student relations with the former exerting both direct and indirect effects. On the contrary, the negative effects of performance goal structures were not buffered by the presence of high levels of personal performance goals. The findings have significant implications for educational practice in terms of the importance of classroom contexts as predictors of classroom relatedness specifically where mastery goals are concerned.     

Teacher and Classroom Context Effects on Student Achievement: Implications for Teacher Evaluation

The Tennessee Value-Added Assessment System (TVAAS) has been designed to use statistical mixed-model methodologies to conduct multivariate, longitudinal analyses of student achievement to make estimates of school, class size, teacher, and other effects. This study examined the relative magnitude of teacher effects on student achievement while simultaneously considering the influences of intraclassroom heterogeneity, student achievement level, and class size on academic growth. The results show that teacher effects are dominant factors affecting student academic gain and that the classroom context variables of heterogeneity among students and class sizes have relatively little influence on academic gain. Thus, a major conclusion is that teachers make a difference. Implications of the findings for teacher evaluation and future research are discussed.     

The relationship between science process abilities of teachers and science achievement of students: An experimental study

The objective of this experimental study is to investigate the relationships among science teacher characteristics and student outcomes. The selected characteristics of teachers are their understanding of science processes and their ability to control variables, and the outcomes of students are the achievement in science contents and processes. The results support the hypothesized relationships and show that the teacher ability to control variables is a more valuable characteristic than the understanding of science processes for student achievement. Conclusions are drawn about the implications for the education of science teachers.     

How do student teachers reflect on their practice through practicum courses? A case study from Iran

The present study investigates the nature of Iranian student teachers’ reflections and their professional development in the context of teacher education practicums. The participants were student teachers (N = 41) enrolled in teacher education colleges at Farhangian University in Tehran, Iran. A total of 620 reflective writing excerpts were coded using deductive content analysis across three cohorts in three different practicums during a two-year period. To analyse the data, this study applied a rubric for evaluating student teachers’ reflections developed by Ward and McCotter. The analysis also involved Friedman’s test and follow-up Wilcoxon tests. The results show that routine levels of reflection significantly decreased across the three practicums, while technical levels of reflection significantly increased. The higher levels of reflection, namely dialogic and transformative levels, were rarely found in student teachers’ reflective writings across the practicums. This study discusses the need both to develop appropriate methods to guide student teachers in centralized contexts such as Iran and to investigate further aspects that enhance or hinder progress in the quality of reflection in teacher education.     

Teachers' attributions for students' low achievement: A validation of cooper and good's attributional categories

Teachers' explanations for students' low achievement were reliably classified using the attributional coding system proposed by Cooper and Good (1983). Teachers most frequently attributed low achievement to a typical pattern of low effort. They viewed acquired student characteristics (e.g., low motivation, poor work habits) as more important than either teacher variables or classroom variables in explaining students' low achievement. Implications of these attribution patterns for improving student achievement and for developing student self-esteem are discussed.
