Using the Science Writing Heuristic Approach to Enhance Student Understanding in Chemical Change and Mixture

This study investigated the effect of the Science Writing Heuristic (SWH) approach on grade 9 students’ understanding of chemical change and mixture concepts. Four intact classes taught by two chemistry teachers from a Turkish public high school were selected for the study; one class was assigned as the treatment group, and the other class was assigned as the comparison group. Students in the treatment group were instructed by the SWH approach, while those in the comparison group were instructed with traditionally designed chemistry instruction. Tests measuring students’ conceptual understanding in the units of chemical change and mixture were administered as pre- and posttest for both groups. At the end of the instruction, semistructured interviews were conducted with 13 students from the treatment group and eight students from the comparison group. ANCOVA results revealed that the SWH approach was superior to the traditional approach on students’ understanding of chemical change and mixture concepts. Interview results indicated that students in the treatment group demonstrated better scientific understanding of chemical change and mixture concepts compared to those in the comparison group.     

Using the Internet to Enhance Student Understanding of Science: The Knowledge Integration Environment

We have developed the Knowledge Integration Environment (KIE) to promote lifelong learning. We believe that science courses can promote lifelong learning by offering students science models that apply to problems they encounter in their everyday lives and by engaging students in personally relevant science projects where they connect science models to typical science resources such as those found on the Internet. Our instructional framework, Scaffolded Knowledge Integration (SKI), guides the design of the Knowledge Integration Environment. In this paper we describe the Knowledge Integration Environment and report results of “design experiments” carried out to guide improvement of Knowledge Integration Environment instruction as well as to help us improve our understanding of lifelong learning.     

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.     

Assessing Student Attitudes Toward Sexual Assault by Using a Mock Trial

Despite the prevalence of sexual assault on college campuses, college students’ views regarding rape continue to be an understudied area. Using criminal justice and sociology students who either attended a mock sexual assault trial or viewed the trial video in their class, this study examined students’ attitudes toward rape and rape myth acceptance. Surveys assessed what students believed the verdict should be and why, along with questions surrounding rape myths and beliefs regarding women. Results indicate that female students were more likely to find the defendant guilty. None of the attitudinal variables or plans to work in the criminal justice system, however, had an effect on the verdict. Multiple factors such as gender, race, and hostility toward women influenced attitudes regarding rape myths. These findings suggest that attitudes may be less important when determining sexual assault defendants’ guilt than the facts of the case. Policy implications are discussed.     

STEM Integration in Middle School Life Science: Student Learning and Attitudes

In many countries around the world, there has been an increasing emphasis on improving science education. Recent reform efforts in the USA call for teachers to integrate scientific and engineering practices into science teaching; for example, science teachers are asked to provide learning experiences for students that apply crosscutting concepts (e.g., patterns, scale) and increase understanding of disciplinary core ideas (e.g., physical science, earth science). Engineering practices and engineering design are essential elements of this new vision of science teaching and learning. This paper presents a research study that evaluates the effects of an engineering design-based science curriculum on student learning and attitudes. Three middle school life science teachers and 275 seventh grade students participated in the study. Content assessments and attitude surveys were administered before and after the implementation of the curriculum unit. Statewide mathematics test proficiency scores were included in the data analysis as well. Results provide evidence of the positive effects of implementing the engineering design-based science unit on student attitudes and learning.     

Perception of Teacher,Home Support and Achievement in Attitudes towards Science

This study investigated the relationships of attitudes towards science with perception of the science teacher, home support and science achievement among a sample of Secondary Two (8th Grade) students. Using the full LISREL model, it was found that the perception of the science teacher was the most significant factor in the development of positive attitudes towards science. Achievement in science was also a significant factor for both girls and boys. Home support was, however, a significant factor for girls but not for boys.     

Using a Geriatric Mentoring Narrative Program to Improve Medical Student Attitudes Towards the Elderly

This study examined first-year medical student attitudes concerning the elderly before and after instituting a geriatric mentoring program. The program began and ended with a survey designed to assess students' attitudes toward the elderly. During the mentoring program, students visited the same senior for four visits throughout the academic year. After each visit, students were required to write a narrative that included reflections on assigned themes. Comparisons of pre- and postsurvey data indicated that students became more positive in their attitudes toward older patients after the geriatric experience. Narratives indicated students were highly engaged in the visits with their seniors.     

The College Classroom as a Community: Impact on Student Attitudes and Learning

Abstract. This study is an exploration of the "sense of community" in a college classroom. The construct was successfully developed by incorporating six variables borrowed from neighborhood community research. Sense of community scores significantly predicted students' classroom attitudes, perception of learning, and actual performance on course exams.     

Student Performance and Attitudes in a Contingency Management Course

Grade performances in a personalized instruction course are compared with those in traditionally-taught courses for students with good, average, and poor academic records. Average and poor students perform much better in a personalized instruction course than in traditionally-taught courses, and good students perform somewhat better. Course evaluation results suggest three factors that contribute to the particular effectiveness of contingency management techniques with average to poor students. 1.) Students tend to perceive the personalized instruction course as requiring a large amount of work, relative to their other courses for the semester, and to match their work input into the course with this perception. 2.) The method appears to produce “self-generated” reinforcers such as feelings of achievement and interest in course content which are unusual experiences for these students. 3.) Aspects of the technique modify poor study habits in a direction that leads to higher grade performance.     

科学与旋(玄)学是互补的

发生在20世纪20年代关于科学与玄学的那场争论,双方都是各执一偏的。这主要是他们都还没有弄清科学和旋(玄)学的本质及其绝对相对的关系。其实,科学是静态学,旋(玄)学是动态学;科学是绝对的,旋(玄)学是相对的。可见,科学与旋(玄)学之间的关系是互补关系,而不是相互排斥,你死我活的敌对关系。     

Virtual Transgenics: Using a Molecular Biology Simulation to Impact Student Academic Achievement and Attitudes

The transgenic mouse model is useful for studying the causes and potential cures for human genetic diseases. Exposing high school biology students to laboratory experience in developing transgenic animal models is logistically prohibitive. Computer-based simulation, however, offers this potential in addition to advantages of fidelity and reach. This study describes and evaluates a computer-based simulation to train advanced placement high school science students in laboratory protocols, a transgenic mouse model was produced. A simulation module on preparing a gene construct in the molecular biology lab was evaluated using a randomized clinical control design with advanced placement high school biology students in Mercedes, Texas (n?=?44). Pre-post tests assessed procedural and declarative knowledge, time on task, attitudes toward computers for learning and towards science careers. Students who used the simulation increased their procedural and declarative knowledge regarding molecular biology compared to those in the control condition (both p?<?0.005). Significant increases continued to occur with additional use of the simulation (p?<?0.001). Students in the treatment group became more positive toward using computers for learning (p?<?0.001). The simulation did not significantly affect attitudes toward science in general. Computer simulation of complex transgenic protocols have potential to provide a ??virtual?? laboratory experience as an adjunct to conventional educational approaches.     

The Effects of Dichotomous Attitudes toward Science on Interest and Conceptual Understanding in Physics

The literature on students' attitudinal constructs in science education asserts that students hold dichotomous attitudes toward science (AS). For instance, studies from the Relevance of Science Education project reveal that students possess negative attitudes in terms of their favourableness toward school science, preference toward scientific careers, and emotional states toward science (negative intrinsic AS), despite their positive perception that science is important for society (positive extrinsic AS). The issue demands in‐depth examination, since not enough science educators have studied the effects of the dichotomous AS on science education. Rather, they have attempted to improve the uncategorised AS for stimulating student achievement in science education. Hence, the aim of this study is to clarify how the dichotomous attitude (intrinsic AS and extrinsic AS) relates to the two educational products in science: interest inventory and conceptual understanding. One hundred and sixteen physics learners in Japan were sampled for fitting the structural equation model in this study. Our final model validated by LISREL suggests that intrinsic AS exclusively stimulate students' interest and conceptual understanding in physics, while extrinsic AS fail to play their expected role. Finally, features of the sampled 10th‐graders and their dichotomous AS are further interpreted with the prevalent concept of the hidden curriculum.     

Effects of a Science Education Module on Attitudes towards Modern Biotechnology of Secondary School Students

This article evaluated the impact of a four‐lesson science module on the attitudes of secondary school students. This science module (on cancer and modern biotechnology) utilises several design principles, related to a social constructivist perspective on learning. The expectation was that the module would help students become more articulate in this particular field. In a quasi‐experimental design (experimental‐, control groups, and pre‐ and post‐tests), secondary school students’ attitudes (N = 365) towards modern biotechnology were measured by a questionnaire. Data were analysed using Chi‐square tests. Significant differences were obtained between the control and experimental conditions. Results showed that the science module had a significant effect on attitudes, although predominantly towards a more supportive and not towards a more critical stance. It is discussed that offering a science module of this kind can indeed encourage students to become more aware of modern biotechnology, although promoting a more critical attitude towards modern biotechnology should receive more attention.

Longitudinal Study of Student Attitudes in a Biology Program

This is among the first longitudinal studies to report student attitudes across 4 yr of a university program. We found that the attitudes of students in biology become significantly more expert-like from the first year to the fourth year of the program, that is, there was a significant positive shift in students’ overall percent favorable scores from 64.5 to 72%, as opposed to the expert response, which averaged 90%. There was a significant positive shift for the real world connection category (78–85%), the enjoyment (personal interest) category (74–82%), and the conceptual connections/memorization category (66–74%). Moreover, there was a significant correlation between students’ overall percent favorable scores and performance (cumulative grade point average) at the end, but not at the beginning, of the fourth year, with high-performing students having significantly more expert-like attitudes than low-performing students. The correlation between percent favorable score and performance was the strongest for the problem solving: synthesis and application category, in which the highest-performing students finished their fourth year with 90% favorable compared with 35% favorable for the lowest-performing students. A comparison of these results with previously reported results and their implications for teaching are discussed.
