Effects of thematic‐based,hands‐on science teaching versus a textbook approach for students with disabilities

Institutions of higher education, states, and local K–12 districts have been challenged to improve math and science education for our nation's students. In the past few years, there has been renewed interest in inquiry‐based, activity‐oriented instruction in science for students with disabilities. Yet, there still exists the need for further empirical evidence to support instructional improvements for students with more involved emotional and behavioral disabilities. This study describes a program in which 18 middle school students with serious emotional disturbances were instructed, over the course of 8 weeks, on “Matter” by two different instructional approaches. Students in one classroom received a traditional textbook approach to science content, whereas students in another classroom received science instruction by a hands‐on, thematic approach. Over the course of instruction, data were collected regarding students' behavior and achievement. Results indicate that, overall, students in the hands‐on instructional program performed significantly better than the students in the textbook program on two of three measures of science achievement, a hands‐on assessment and a short‐answer test. The students did not differ on a multiple‐choice format test. With regard to behavior, there were no significant differences in behavioral problems found between the two groups of students over the course of the study. Findings are discussed in relation to instructional implications for students with disabilities in the science classroom. © 2005 Wiley Periodicals, Inc. J Res Sci Teach 42: 245–263, 2005     

School climate and teacher beliefs in a school effectively serving poor South Carolina (USA) African-American students: A case study

This study examined the roles of school climate, teacher expectations, and instructional practices in one elementary school in South Carolina (USA) that produced effective achievement outcomes with poor and minority students. Survey data, teacher interviews, and classroom videotaping was used to identify school characteristics and instructional behaviors of six teachers nominated by colleagues as exemplary. The school was characterized by an emphasis on high student expectations, school staff cohesiveness, engaging instruction, high parent involvement, and multicultural instruction integrated with curriculum. The practices identified are consistent with literature on effective American schools; and the practices are key aspects of the sound instruction of poor and minority children. Teachers stated that teacher education programs did not prepare them to teach these students and that they had to learn this on the job.     

Social Activism in Elementary Science Education: A science,technology, and society approach to teach global warming

As part of a large‐scale instructional intervention research, this study examined elementary students’ science knowledge and awareness of social activism with regard to an increased greenhouse effect and global warming. The study involved fifth‐grade students from five elementary schools of varying demographic makeup in a large urban school district in the United States. The study was based on the analysis of students’ responses to a writing prompt addressing an increased greenhouse effect and global warming at the beginning of and at the completion of instruction over the school year. The results indicate that students with adequate science knowledge tended to express activism more frequently, and that their expression of activism increased as they gained better science knowledge after the instruction. The results highlight the importance of effective instruction of this contemporary and controversial issue with K‐12 students, so that they come to be aware of this societal problem, take action in solving the problem, and become socially responsible youth and adults.     

Collaborative Consultation: The San Juan Unified School District Project

Critically needed in the area of school consultation are field-based, evaluation reports of outcomes of actual implementation of school consultation. This article is such a report, describing how the Resource/Consulting Teacher model was implemented with resource specialists in a pilot program in Sacramento, California. We describe: (a) the procedures necessary to bring about such an implementation, (b) the district itself, and (c) the training efforts made to prepare the resource specialists for the new role. Emphasis is placed on how 13 resource specialists formed a collaborative working group among themselves, as well as their efforts to engage in collaborative consultation with classroom teachers and building administrators to assist certain special education students and certain students at risk for school failure. Preliminary evaluation data are included that describe the progress of individual students and groups of elementary students (N = 79) who received specialized remedial reading instruction, and individual students who received intervention to increase appropriate social behaviors. The specialized reading and behavior instruction was provided to special education students in resource rooms and general classrooms; the at-risk student instruction was in general education programs. As a result, 29 special education students were mainstreamed back into their general education reading classes, 7 students were nearly ready to be returned, and 9 students were totally dismissed from the special education program and reinstated as general education students.     

Examining tensions in the socioscientific issues classroom: Students' border crossings into a new culture of science

In the socioscientific issues (SSI) classroom, students need to cross the border between the subcultures of science (i.e., school science vs. everyday science). Traditional school contexts tend to present science as positivistic knowledge and unshakable truth unaffected by sociocultural factors. In contrast, everyday science, including SSI, is more nuanced, context-based, socially and culturally embedded. Thus, learning in an SSI classroom requires students to make additional efforts to successfully navigate between the subcultures of science. The expected norms located within these two educational contexts can create academic and sociocultural tensions for students. It is therefore necessary to explore the tensions caused these differential norms in order to successfully implement SSI. Through the lens of cultural-historical activity theory, we attempted to identify possible tensions that originate by implementing SSI instruction in a setting where teachers and students are accustomed to traditional lecture-based classroom instruction. One hundred thirty ninth graders at a public middle school located in Seoul, South Korea, participated in SSI programs on genetic modification technology during seven class periods over three to 4 weeks. Data was collected by classroom observation, audio-taping while students participated in various types of discourse, and semistructured interviews. We identified four noteworthy phenomena including intolerance of uncertainty, scientism, a sense of rivalry, and reaching an expedient and easy consensus. By revealing and understanding these tensions and phenomena, we aim to help inform teachers (and teacher educators) recognize instructional clues that can change not only students' epistemological views and attitudes toward science and science classes, but also better navigate the norms of classroom culture.     

Research–Practice Partnerships to Support the Development of High Quality Mathematics Instruction for All Students

The gap in achievement in mathematics between at-risk students and their more advantaged counterparts is a persistent problem of the U.S. education system. Although some research-based curricula and pedagogy have demonstrated promise in supporting students from diverse backgrounds to develop conceptual understanding and procedural fluency in mathematics, scaling up instructional change across a district organization is a significant challenge. The Middle School Mathematics and the Institutional Setting of Teaching (MIST) Project is a research–practice partnership seeking to understand how large urban school districts can support the development of rigorous and equitable middle-school mathematics instruction at scale. This article enumerates the goals and design of this multiyear, multidistrict partnership, and describes one illustrative example of how our partnership activities informed and supported one district's efforts to improve mathematics instruction over multiple years. General recommendations for district–researcher partnerships are discussed.     

Exploring Middle School Students’ Understanding of Three Conceptual Models in Genetics

Genetics is the cornerstone of modern biology and a critical aspect of scientific literacy. Research has shown, however, that many high school graduates lack fundamental understandings in genetics necessary to make informed decisions about issues and emerging technologies in this domain, such as genetic screening, genetically modified foods, etc. Genetic literacy entails understanding three interrelated models: a genetic model that describes patterns of genetic inheritance, a meiotic model that describes the process by which genes are segregated into sex cells, and a molecular model that describes the mechanisms that link genotypes to phenotypes within an individual. Currently, much of genetics instruction, especially in terms of the molecular model, occurs at the high school level, and we know little about the ways in which middle school students can reason about these models. Furthermore, we do not know the extent to which carefully designed instruction can help younger students develop coherent and interrelated understandings in genetics. In this paper, we discuss a research study aimed at elucidating middle school students’ abilities to reason about the three genetic models. As part of our research, we designed an eight-week inquiry unit that was implemented in a combined sixth- to eighth-grade science classroom. We describe our instructional design and report results based on an analysis of written assessments, clinical interviews, and artifacts of the unit. Our findings suggest that middle school students are able to successfully reason about all three genetic models.     

Using Preservice Teachers to Improve Computer Skills of At-Risk Alternative High School Students

This research examined the impact of preservice teachers delivering individualized instruction of basic computer skills to at-risk, ethnic minority alternative high school students in an urban school district in South Texas. The alternative high school students' achievement of computer skills, motivation to use computers, and self-efficacy as current and future students was assessed. University preservice teachers taught a keyboard/computer skills curriculum developed specifically for this collaborative teaching and learning project in 10 1-hr-long sessions 2 times a week over a 5-week period. A series of 2 by 2 repeated measures analysis of variance showed achievement gains as measured by a survey instrument within the treatment group. This small, preliminary study supports the use of preservice teachers in the delivery of an individualized, computer-based program of instruction for at-risk students.

Integrating mathematics,science, and technology: effects on students

Few studies have examined the student learning effects of integrating science with mathematics and technology. We compared a school that integrated mathematics, science and technology in grade 9 to a school in the same district that taught the three courses separately. The distinguishing feature of the integrating school was the reorganization of instruction in the three subjects to prepare students for seven group projects (involving a total of 25 h) that required the application of knowledge and skill that were shared by the three subjects, as well as learning outcomes that were unique to each. The study detected benefits for students in the integrated setting in terms of their ability to apply shared learning outcomes, student motivation, ability to work together and attitudes to appraisal of group work. Female students in the integrated school had a better understanding of selected science learning outcomes. Attitudes toward mid‐term exams were higher in the control school.

The effects of learning–family conflict,perceived control over time and task-fit technology factors on urban–rural high school students’ acceptance of video-based instruction in flipped learning approach

Flipped learning approach combines video-based instruction (VBI) outside the classroom and problem-solving activities inside the classroom. The success of this instructional approach largely depends on students’ acceptance to learn the video presentation at home during pre-classroom activities. However, there are still very scarce insights regarding the evaluation of students’ eagerness to learn VBI. This paper aims to extend UTAUT model by adding learning–family conflict, perceived control over time and task-fit technology factors to investigate urban–rural high school students’ acceptance of VBI in flipped learning approach. 400 randomly selected students from urban and rural senior high school were used for the study. Structured equation modeling and multi-group analysis using t test were employed to analyze the survey data. The results showed that facilitation condition, task-fit technology, perceived control over time, performance expectancy, and learning–family conflict have positive influence on students’ behavioral intention to use VBI. Surprisingly, the t-test analysis indicated significant differences between groups, suggesting that students in the rural schools have low learning–family conflict, high perceived control over time, and high intention to use VBI than urban students. Detailed results and educational implications are discussed.     

Modifying Negative Attitudes Towards School Work Through Group Contingencies

Teaching a class of secondary school students can be either an exciting or a frustrating experience. Some students tend to be enthusiastic and self-motivated when engaged in certain learning tasks, but the evidence for poor motivation and a lack of enthusiasm is also present. The task of teaching demands that we should not lose sight of the fact that one of our primary responsibilities is to provide effective academic instruction in our classrooms. When we encounter some classroom problems such as negative attitudes towards school work, we should therefore not dismiss the difficulties as insurmountable, nor should we assume that because of their age, behaviour modification procedures will not be effective for secondary school students.     

INSTRUCTIONAL ACTIVITIES AND GROUP WORK IN THE US INCLUSIVE HIGH SCHOOL CO-TAUGHT SCIENCE CLASS

In the US, there is a significant number of learning-disabled high school students included in regular science classrooms. It has been argued that students with learning disabilities can succeed in science if they receive the kind of instruction they need. To facilitate such instruction, the special education teacher is often incorporated into the class along with the learning disabled students. We observed 53 high school science lessons from ten pairs of science and special-education teachers who were responsible for delivering instruction to groups of students, some of whom were learning-disabled. We analyzed narrative notes collected in these lessons reflecting the kinds of classroom activities, organization of work, and teachers’ roles. In addition, we interviewed the teachers individually to gain a better understanding of these inclusive classes. The underlying question of this research was whether inclusive classes with two teachers delivered the type of science education that is better than solo-teaching in addressing the needs of learning-disabled students. Our evidence indicates that even with a special-education teacher present in the class, learning-disabled students usually did not receive a science education that met their needs. We elaborate on the reasons for this problem and make suggestions for improvement.     

CONTENT ANALYSIS OF 1998–2012 EMPIRICAL STUDIES IN SCIENCE READING USING A SELF-REGULATED LEARNING LENS

In this study, we investigated the impact of teaming school-based instructional coaches with science or mathematics middle school teachers to build a community of practice around inquiry instruction. This professional development model began with a 2-week summer institute and continued with four follow-up sessions during the academic school year for the teacher and instructional coach participants. The teachers’ participation in this professional development program with (1) content instruction through inquiry lessons, (2) practice teaching to middle school students, and (3) coach-led reflection improved their understanding of inquiry-based practices and the quality of their classroom inquiry implementation. Professional development experiences that prepare teachers and coaches simultaneously in inquiry and content may help build a shared language for reform and accelerate inquiry instructional changes.     

Examining the Dual Purpose Use of Student Learning Objectives for Classroom Assessment and Teacher Evaluation

The process of setting and evaluating student learning objectives (SLOs) has become increasingly popular as an example where classroom assessment is intended to fulfill the dual purpose use of informing instruction and holding teachers accountable. A concern is that the high‐stakes purpose may lead to distortions in the inferences about students and teachers that SLOs can support. This concern is explored in the present study by contrasting student SLO scores in a large urban school district to performance on a common objective external criterion. This external criterion is used to evaluate the extent to which student growth scores appear to be inflated. Using 2 years of data, growth comparisons are also made at the teacher level for teachers who submit SLOs and have students that take the state‐administered large‐scale assessment. Although they do show similar relationships with demographic covariates and have the same degree of stability across years, the two different measures of growth are weakly correlated.     

Transformational Teaching: Theoretical Underpinnings, Basic Principles, and Core Methods

Approaches to classroom instruction have evolved considerably over the past 50?years. This progress has been spurred by the development of several learning principles and methods of instruction, including active learning, student-centered learning, collaborative learning, experiential learning, and problem-based learning. In the present paper, we suggest that these seemingly different strategies share important underlying characteristics and can be viewed as complimentary components of a broader approach to classroom instruction called transformational teaching. Transformational teaching involves creating dynamic relationships between teachers, students, and a shared body of knowledge to promote student learning and personal growth. From this perspective, instructors are intellectual coaches who create teams of students who collaborate with each other and with their teacher to master bodies of information. Teachers assume the traditional role of facilitating students’ acquisition of key course concepts, but do so while enhancing students’ personal development and attitudes toward learning. They accomplish these goals by establishing a shared vision for a course, providing modeling and mastery experiences, challenging and encouraging students, personalizing attention and feedback, creating experiential lessons that transcend the boundaries of the classroom, and promoting ample opportunities for preflection and reflection. We propose that these methods are synergistically related and, when used together, maximize students’ potential for intellectual and personal growth.     

Student Team Reading and Writing: A Cooperative Learning Approach to Middle School Literacy Instruction

The goal of this project was to create a middle school literacy program that was more responsive to the needs and abilities of early adolescents in urban middle schools. The program components included: (a) cooperative learning classroom processes; (b) a literature anthology for high interest reading material; (c) explicit instruction in reading comprehension; (e) integrated reading, writing, and language arts instruction; and (f) a writing process approach to language arts. The study was conducted in 5 schools in a large urban school district, 2 implementing Student Team Reading and Writing (STRW) and 3 comparison schools. The results indicated that the students in STRW had significantly higher achievement in reading vocabulary, reading comprehension, and language expression. The results suggest that a multifaceted approach to restructuring can effectively improve the achievement of students in urban middle schools.     

The Viability of Combining Academic and Career Pathways: A Study of Linked Learning

In an attempt to reform high schools and prepare students with the knowledge and skills needed for the 21st century, educators and policymakers have turned to programs that combine career and academic pathways. One such program, Linked Learning, has taken up the reform challenge by relying on technical adjustments, rearranging students’ schedules, and integrating career technical education (CTE) with a set of courses that support students’ eligibility for their state and university college system. Linked Learning has attempted to avoid the pitfalls often associated with an earlier vocational education model. This article reports findings from a year-long study of eight schools in five districts whose district leaders and principals have placed Linked Learning at the core of their platform for school reform. Interviews with these educators reveal that while changing the structure of students’ course schedules offered some advantages for students, school principals were challenged to keep their academic and career promises. This qualitative investigation has shown that to understand reform challenges it is essential to examine the broader school, district, and state context in which the reform is embedded. Both structural and cultural considerations must be addressed if high school reform is to more effectively support students.
