The purpose of this study was to determine if the use of molecular drawing software would improve student understanding of polyatomic ions. Using software designed for producing drawings of molecules, students developed drawings of polyatomic ions during a regular activity of the state mandated core curriculum on ions. The sample consisted of students enrolled in chemistry at a rural south Louisiana high school-both Honors and Regular. Pretest and posttest scores were analyzed with a number of covariants. The statistical analysis of test scores indicated that there was no significant difference in the improved test scores between the treatment and control groups. The lack of a significant improvement in test scores fails to mirror the results of other documented studies such as that performed by Wu, Krajcik, and Soloway (2001), which made use of similar representations and produced positive gains in the understanding of formulas. However, interviews that were conducted seemed to indicate that the treatment students did obtain a greater understanding of polyatomic ions than did the control group students. More sensitive test items may be needed to detect changes in understanding caused by the intervention. Despite learning this new computer visualization skill in addition to mastering the traditional content, statistical analysis showed the intervention did not have a detrimental effect on test performance. Through personal observation of student performance in later lessons, some transfer appears to have been achieved amongst the students in the treatment group. The possibility of transfer follows some of the findings of Haskell (2001). It was also observed that students that had the opportunity to utilize the computer software had improved inquiry skills. The average test scores for all groups increased with the greatest increases in the treatment group scores. Despite these gains, there was no significant increase in test scores for the treatment group. Analysis of the Birnie-Abraham-Renner Quick Attitude Differential (Williamson, 1992) scores indicated no correlation between student attitudes and the intervention. From the analysis of the interviews, there is an indication that an improved understanding of polyatomic ion structure resulted from the intervention.

The purpose of this study was to explore the perceptions of developmental students enrolled in a developmental reading course in a community college setting. A reading course questionnaire and interest/attitude inventory was completed by the students. In addition, individual interview were conducted. Eight students participated in the study that addressed more fully the impact of the developmental reading course on their achievement. Research questions sought to explore developmental students past reading experiences, past reading experiences, and perceptions of the developmental reading course. Results of the study suggest that classroom instruction focusing on comprehension and vocabulary activities presented in a developmental reading course in a community college setting was helpful. Some of the case study participants indicated they were able to write better papers in other subject areas and increased their vocabulary skills and comprehension.

<p>According to recent studies, less than half of U.S. students perform at the proficient or advanced levels in mathematics by the time they reach grade 4 and the trend continues through high school. In order to improve instruction many districts have adopted scientifically based researched programs such as Response to Intervention (RTI), which allows for the examination of the effectiveness of the core curriculum that is being used in a school or classroom. In addition, RTI provides school administrators and teachers with educational tools to identify students who may be at-risk of failing and to inform teachers of supplemental instruction needed to build up skills that are identified as weak or lacking. Research on early mathematics skills indicates that skills performance at the kindergarten and first grade level may predict performance at later grade levels. Providing intervention early has been shown to have a positive effect on students' future mathematics success.</p> <p>This study investigated the long-term predictive validity of the AIMSweb measures for kindergarten through grade 2 and the Montana Comprehensive Assessment System (MontCAS). The kindergarten and grade 1 assessments included the Test of Early Numeracy which measures number sense skills that include Oral Counting, Number Identification, Quantity Discrimination, and Missing Number. The grade 1 and 2 Mathematics-Curriculum Based Measures assessed computational fluency. The scores on these K-2 assessments were analyzed to investigate correlations with the grade 3 MontCAS scores of the same students. The results indicated that Number Identification and Quantity Discrimination provided the most explained variance. Overall, the kindergarten scores were stronger indicators of grade 3 performance than the grade 1 scores.</p> <p>A sequential multiple regression model was also used to explore which of the TEN measures along with the hierarchy of tests from kindergarten through grade 2 had the greatest explained variance for the grade 3 MontCAS. The results showed that each test from kindergarten to grade 1 increased the predictability of the grade 3 MontCAS scores; however, the grade 2 scores did not contribute to the predictability of the grade 3 assessment. Overall, Oral Counting indicated the highest explained variance using this model.</p>

This study is a qualitative, autoethnographic study documenting the process of writing and submitting a charter school application in Post-Katrina New Orleans. The focus of the study is my professional journey to this point, and the journey the charter team. The school's mission and curriculum is unique and centered on special needs students who are "at-risk" for learning due to language and learning differences. Particular aspects of curriculum and instruction, climate and culture, professional development, student achievement goals, administration, and operational issues were developed by this team. The aim of the study is for this investigation to contribute to the body of knowledge about educating "at-risk" learners and designing innovative schools. The focus of the study is on the epistemological, methodological, and political insights encountered. The primary question for this investigation is: What are the components of a successful charter school for "at-risk" students? Secondary questions include: How do we determine who is "at-risk"? How do we balance state demands with best practice teaching for these "at-risk" students? Where does appropriate funding come from for such a project? Hopefully this narrow based study will lead to specific program improvement and evolvement.

This study investigated the impact of a media literacy education plan on the reading test scores of the Florida Comprehensive Assessment Test (FCAT) at an urban high school in Central Florida. A team of 9th and 10th grade teachers created a professional learning community and developed a treatment to enhance language arts instruction with various forms of media. This media literacy education plan included four lessons utilizing media such as television commercials, magazine photographs and the Internet; the lessons were taught during the four months leading to the administration of the 2007 FCAT. Data were gathered from the 2006 and 2007 FCAT scores of students in a control and treatment group. Using these pre test and post test data, statistical analysis comprised two independent t-tests and one repeated measures ANOVA. The data revealed statistical significance at the 9th and 10th grade level, but did not show statistical significance at any particular reading level (Levels 1-5). Implications from this study included strong professional learning communities produce effective teachers and that student achievement increases when a media literacy education plan is included in English Language Arts instruction. Furthermore, this study illustrates the need to embrace modern media as viable classroom instructional tools. Recommendations were made for further research utilizing different materials, different forms of media, different student populations. This study also concluded that further qualitative research be conducted. Ultimately, this study makes a strong argument for the inclusion of media and media literacy education in the secondary English Language Arts classroom.

For several years emerging trends in special education services have favored inclusion for students with disabilities. Concurrent to this evolution of philosophy in special education has been the advent of what could be considered inclusive instructional practices--those methods that aid in the successful inclusion of students with disabilities. These inclusive practices include co-teaching, cooperative learning, peer-mediated instruction, positive behavioral support, embedded learning strategies, and content-enhancements (Ehren, Lenz, & Deshler, 2005; King-Sears, 1997). As inclusive placements become an increasingly common standard of practice, particularly for students with learning disabilities, the need to assist general educators in establishing inclusive classrooms becomes a major priority. It is logical then to prioritize the propagation of inclusive practices in general education classrooms--practices that would take into account the natural diversity of student populations likely to be present in American classrooms. Cooperative learning, in the form of Literature Circles, is offered in this study as a highly effective method for laying the groundwork for inclusion. This study, rooted in the theory of anchored instruction, attempted to address the need for incorporating inclusive practices by investigating the potential for students with learning disabilities to implement Literature Circles by viewing video models. This research evaluated the impact of video models on three levels--the extent to which the video models improve the ability for students with learning disabilities to a) learn the foundational information and rationale of a strategy, b) implement the strategy effectively, and c) improve academic outcomes by implementing the strategy. Finally, an attempt was made to further probe student perception of learning a strategy from a video model through focus group interviews. Data was collected using a quasi-experimental design. Forty-nine classrooms were randomly assigned to video-based and traditional treatments. Students attempted to implement Literature Circles in their middle school social studies classes. Following data collection, quantitative statistical analysis was completed using Multivariate Analysis of Variance (MANOVA) to examine group differences in knowledge of the essential elements of the strategy, implementation of the strategy, and content achievement. Qualitative analysis of student focus group responses was completed by scrutinizing transcripts for general themes (Erickson, 1986). This study made a connection between lines of research on video-based anchored instruction for students with learning disabilities and video-anchors in teacher preparation. The full sample of 196 students, including 43 students with learning disabilities, demonstrated significantly more effective implementation of Literature Circles. Students in the video model focus group indicated that they benefited from the explicit, positive peer models demonstrated in the video. The continued proliferation of visual images in the form of video-based models represents a positive step toward increasing available resources to students and teachers and ultimately improving outcomes for students with learning disabilities.
