ABSTRACT:  More than 76 million persons become ill from foodborne pathogens in the United States each year. To reduce these numbers, food safety education efforts need to be targeted at not only adults, but school children as well. The middle school grades are ideal for integrating food safety education into the curriculum while simultaneously contributing to national and state education standards in science, technology, and family and consumer sciences. For this project, a multimedia, self-paced online resource for delivering a food safety curriculum to middle school children was developed. Animated characters were used to deliver the lesson content. The application also included video segments, quiz feedback, and interactive games and activities. The effectiveness of the Web site was evaluated using validated cognitive and attitudinal assessment tools, and by comparing student cognitive gains to individual student learning styles. Participants were recruited from 6 middle schools in 5 states, totaling 217 students (20 sixth graders, 157 seventh graders, and 40 eighth graders). The results show that students had statistically significant modest gains in pretest to posttest knowledge and enjoyed using the Web site. The 6th grade students had significantly lower pretest to posttest improvement compared to 7th and 8th grade students, suggesting that this program may not be appropriate for this grade level. Furthermore, the results indicate that this Web-based computer application meets the needs of varying individual student learning styles.  相似文献

The research reported in this article sought to provide a broader understanding of high school science students as persons by describing the personal thoughts, or everyday thinking, about a question relevant to science: What is Nature? The purpose was to gain an understanding of students' fundamental beliefs about the world on the basis that developing scientific literacy can be successful only to the extent that science finds a niche in the cognitive and cultural milieu of students. The theoretical background for this research came from cultural anthropology and the methodology was interpretive, involving student interviews. The assertions of the study in summary form were: (a) The ninth‐grade students in the study tended to discuss Nature using several different perspectives (e.g., religious, aesthetic, scientific, conservationist). A rich breadth of perspectives typically characterized any one student's discussion of Nature. (b) After 9 years of schooling, however, the level of science integration within everyday thinking remained low for many of these ninth graders. In their discussions of Nature, most volunteered little school knowledge of science. They were aware of school science topics such as the ozone layer, rain forests, and the Big Bang theory. Such topics were voluntarily mentioned but usually without elaboration even when asked. (c) Science grade success was not correlated with the concepts these ninth graders typically chose to use in a discussion about the natural world. The students with the most grade success in science had not necessarily grasped fundamental concepts about Nature and science. (d) Regardless of school grade success, including school science grade success, most of the ninth graders attached considerable importance to personal experiences with Nature. Their environmental inclinations were strong. The article ends with a discussion of the implications. © 1999 John Wiley & Sons, Inc. J Res Sci Teach 36: 541–564, 1999  相似文献

The purpose of this study was to investigate and compare the impact of Internet Virtual Physics Laboratory (IVPL) instruction with traditional laboratory instruction in physics academic achievement, performance of science process skills, and computer attitudes of tenth grade students. One-hundred and fifty students from four classes at one private senior high school in Taoyuan Country, Taiwan, R.O.C. were sampled. All four classes contained 75 students who were equally divided into an experimental group and a control group. The pre-test results indicated that the students’ entry-level physics academic achievement, science process skills, and computer attitudes were equal for both groups. On the post-test, the experimental group achieved significantly higher mean scores in physics academic achievement and science process skills. There was no significant difference in computer attitudes between the groups. We concluded that the IVPL had potential to help tenth graders improve their physics academic achievement and science process skills.  相似文献

We investigate the relationship between teacher licensure test scores and student test achievement and high school course-taking. We focus on three subject/grade combinations—middle school math, ninth-grade algebra and geometry, and ninth-grade biology—and find evidence that a teacher's basic skills test scores are modestly predictive of student achievement in middle school math and highly predictive of student achievement in high school biology. A teacher's subject-specific licensure test scores are a consistent and statistically significant predictor of student achievement only in high school biology. Finally, we find little evidence that students assigned to middle school teachers with higher basic-skills test scores are more likely to take advanced math and science courses in high school.  相似文献

This study was designed to assess whether the level of performance of selected Jamaican 11th-grade physics students on some numerical problems on the energy concept was satisfactory and if there were significant differences in their performance linked to their gender, socioeconomic background (SEB), school location, English language and mathematical abilities. The 331 sampled students consisted of 213 boys and 118 girls; 197 students were from a high SEB and 134 students from a low SEB; 296 students were from seven urban schools and 35 students from three rural schools; 112, 153 and 66 of the students had high, average and low English language abilities, respectively, while 144, 81 and 106 of the students had high, average and low mathematical abilities, respectively. An Energy Concept Test (ECT) consisting of six structured numerical questions was employed for data collection. The results indicated that although the students’ level of performance was regarded as fairly satisfactory, there was a lot of room for improvement. There were statistically significant differences in the students’ performance on the ECT linked to SEB, and mathematical abilities in favour of students from a high SEB, and high mathematical abilities, respectively. There was a positive, statistically significant but weak correlation between the students’ (a) mathematical abilities, and (b) English language abilities and their performance on the ECT, while there were no correlations among their gender, school location, and SEB and their performance on the ECT.  相似文献

Research Findings: The purpose of this study was to investigate the factorial structure of kindergarten children's mathematics and science process skills and the impact of children's competencies in process skills on their performance on mathematics and science achievement tests in 3rd grade. A subset of the Early Childhood Longitudinal Study–Kindergarten cohort data set (n = 8,731) was analyzed using multilevel structural equation modeling. Results demonstrated that science and mathematics process skills were highly related at the construct level but not at the indicator level, as was anticipated. Kindergarten children's competency in mathematics process skills was a strong predictor of their performance on science and mathematics achievement tests in the 3rd grade. However, children's competency in science process skills was only a significant predictor of their performance on a science achievement test in the 3rd grade. Moreover, socioeconomic status and gender were statistically significant predictors of process skills and performance on achievement tests. Practice or Policy: The findings of the present study suggest that the development of children's science and mathematics process skills should be supported utilizing integrated inquiry-based science and mathematics activities to help children recognize the connection between mathematics and science and to contribute to their science and mathematics achievement in later grades.  相似文献

The purpose of this study was to collect and analyze data on sexual differences in secondary school students' attitudes towards science. Attitudinal differences were also analyzed for the independent variables of science programs and grade levels. Data were collected from 988 students using a modified version of the Fennema-Sherman Mathematics Attitude Scales to represent attitudes toward science. Reliabilities of the modified science subscales were all high ( > 0.83). Multivariate analysis of variance (MANOVA) was used to analyze the data for the main and interaction effects of the independent variables of sex (male, female), grade level (10th, 11th, 12th), and science program (advanced placement, academic, general, terminal). Significant differences (p < 0.05) were indicated for all main effects (sex, grade, science program). Interaction effects were not found. Mean separations for the various levels of sex, grade, and science program were performed for all attitudinal subscales. Females evidenced a significantly more positive attitude (p ? 0.01) than males on three subscales: Attitude Toward Success in Science Scale, Science as a Male Domain Scale, and Teacher Scale. Although not significant, males evidenced more positive attitudes on all the remaining five subscales. Eleventh graders evidenced significantly more positive attitudes than tenth graders on all but the Effectance Motivation Scale. Students in 11th grade had more positive attitudes than 12th-grade students on all scales but Science as a Male Domain Scale; however, these differences were not significant. Tenth graders differed significantly from 12th graders on three subscales; Science Usefulness Scale, Confidence in Learning Science Scale, and Teacher Scale. Positive attitudes decreased from advanced placement to terminal programs. Academic students did not differ significantly from general students except on the Father Scale; however, they were significantly different (more positive) from the terminal students for all subscales. General students were also significantly different from terminal students except on the three subscales of Attitudes Toward Success in Science, Science as a Male Domain, and Effectance Motivation.  相似文献

The present study challenges the assumption that cultural capital benefits students' academic achievement regardless of their educational stages. Meta-analytic results from 105 studies published 2000–2017 indicated that nine cultural capital variables (e.g., home educational resources, maternal and paternal education, parental expectations, cultural participation, home support, school participation) benefited all students while five cultural capital variables exhibited a differentiated pattern of relationship with student achievement depending on educational stages. First, compared to students from higher grade levels, kindergarteners benefited most from parental education, parental academic emphasis, and parent-child reading. Second, compared to 1st–6th graders, 7th-12th graders benefited more from academic discussions. Third, compared to 1st–6th graders, both kindergarteners and 7th-12th graders benefited from parental school involvement. These results provide compelling evidence that while there are some forms of cultural capital that all students will benefit from, there are others whose association with students’ achievement depends on their educational stages.  相似文献

This study examined the relationship of school ethical climate and students' school performance within the context of a Chinese high school. Gender and grade‐level differences in ethical climate perceptions were also explored. Survey data on perceptions of school ethical climate based upon the dimensions of student‐to‐teacher, student‐to‐student and teacher‐to‐student interactions and relationships were obtained from 754 students. Results of the study showed that students' perceptions of their high school's ethical climate were related to academic achievement, gender and grade level. Students' involvement in extracurricular activities and student leadership generally did not seem to relate to their perceptions of ethical climate. Based upon these findings, the school's moral education intervention programs should increase their focus on the area of teacher‐to‐student relationships and interactions and the subgroups of male students, students in higher grades and students with lower academic achievement. Implications for future research on school climate are also discussed.  相似文献

This paper explores 30 students' views on the purposes for studying US history. Twelve students were 5th graders, 12 were 8th graders, and six were high school students. Responses were drawn from detailed interview protocol data compiled over three years in the context of a larger research programme that extensively studied the teaching and learning practices in five American history classrooms, two at 5th grade, two at 8th grade, and one at the high school level. Two questions from the protocol frame this exploration:'Why do you think they teach you American history in school?' and 'How might learning American history help you in your life away from school?'. Responses indicated that (a )all the students were able to construct some answer to the questions; (b ) rationales for learning history varied considerably by age, interest and ethnic background, but versions of the Santayanan rationale and utilitarian responses were most common; (c ) students seemed initially puzzled by the questions as though they had never considered them before; and (d ) students appeared to hold a 'stabilized', consensus view of history, meaning that they thought of history as a collection of putative facts and that their task was to learn them. Implications are considered against the backdrop of teaching and learning American history and the current history curriculum.  相似文献

Remote learning during the COVID pandemic has led to short- and long-term consequences for students' learning. So far, data on learning loss in early schooling have been limited. In this paper, we evaluate the effect of remote learning on 1st graders' school readiness skills and 2nd–8th graders’ performance in mathematics, reading and science using rich data collected in Hungary before and during the pandemic (n ≈ 55,000). The results show that kindergarten children and 1st–4th-grade students were significantly negatively affected by COVID restrictions compared to their older peers. This difference was extremely large in schools with a high share of disadvantaged students. More specifically, 1st–4th-grade low-SES students made little or no progress while learning from home.  相似文献

This study aimed at establishing if the level of performance of 500 Jamaican Grade 11 students on an achievement test on the concept of respiration was satisfactory (mean=28 or 70% and above) or not (<70%); if there were statistically significant differences in their performance on the concept linked to their gender, cognitive abilities in biology, self-esteem, school location, socioeconomic background (SEB), school-type and school location; and if there were significant relationships among the six variables and the students’ performance. The sample (n=500) consisted of 212 boys and 288 girls selected from five all-boys’ schools (119 students), five all-girls’ schools (159 students), and six coeducational schools (222 students). The students were from six rural schools (137 students) and ten urban schools (363 students), out of which 291 were from a high SEB and 209 were from a low SEB. A 40-item multiple choice test on respiration and a self-esteem questionnaire were used to collect data. The results revealed that the students’ level of performance (mean=23.44 or 58.60%, SD=6.86) was regarded as fairly satisfactory; there were statistically significant differences in the students’ performance on respiration based on their cognitive abilities, and school-type in favour of students with high cognitive ability in biology and all-boys’ schools respectively. There was a positive statistically significant but weak relationship between the students’ (a) cognitive abilities, and (b) school-type and their performance on respiration.  相似文献

Abstract

This study compares achievement levels for high ability students attending charter schools and students in traditional public schools in Georgia. Researchers examined student achievement (as assessed by the state's Criterion-Referenced Competency Tests) using three comparison groups: students in the closest traditional schools with similar grade levels, schools with similar demographics, and comprehensive school reform schools. Hierarchical loglinear analysis was used to determine the impact of school type and student demographic variables on student achievement mobility (i.e., the degree to which students, from 2004 to 2005, moved into or out of the top 10% of each grade level on the CRT mathematics subtest). Results for the first comparison did not provide evidence of a significant relationship between school type and achievement mobility, but results for the second and third comparisons suggest that Black students generally experienced positive or neutral achievement mobility in traditional schools and negative mobility in charter schools; White students generally saw negative achievement mobility in traditional schools and neutral to positive mobility in charter schools. Implications for the study of gifted education and gifted students within charter schools are discussed.  相似文献

This study investigated Jamaican 9th graders' attitudes towards science and if there were statistically significant differences in their conceptual knowledge of matter linked to their gender, attitudes towards science, school-type, and socio-economic background (SEB). The 216 participating students comprised 109 males and 107 females; 65, 98 and 53 (25%) students had highly favourable, moderate and low attitudes towards science respectively; 73 boys were from two all-boys' schools, 71 girls from two all-girls' schools, 36 boys and 36 girls were from two coeducational schools; 108 students each were from a high and a low SEB, all in Kingston. Attitudes to science questionnaire and the knowledge of matter test were used to collect data. The results showed that most of the students exhibited favourable attitudes to science; there were statistically significant differences in the students' knowledge of matter linked to attitudes to science, and school-type in favour of the boys, students with highly favourable attitudes to science, and students in all-boys' schools respectively. There was a positive, statistically significant but weak relationship between the students' (a) attitudes to science, and (b) school-type and their knowledge of matter, while there was no relationship between their (c) gender, and (d) SEB and their knowledge of matter.  相似文献

The purposes of this study were to validate an instrument of attitudes toward science and to investigate grade level, type of school, and gender differences in Taiwan’s students’ personality traits and attitudes toward science as well as predictors of attitudes toward science. Nine hundred and twenty‐two elementary students and 1,954 secondary students completed the School Student Questionnaire in 2008. Factor analyses, correlation analyses, ANOVAs, and regressions were used to compare the similarities and differences among male and female students in different grade levels. The findings were as follows: female students had higher interest in science and made more contributions in teams than their male counterparts across all grade levels. As students advanced through school, student scores on the personality trait scales of Conscientiousness and Openness sharply declined; students’ scores on Neuroticism dramatically increased. Elementary school and academic high school students had significantly higher total scores on interest in science than those of vocational high and junior high school students. Scores on the scales measuring the traits of Agreeableness, Extraversion, and Conscientiousness were the most significant predictors of students’ attitudes toward science. Implications of these findings for classroom instruction are discussed.  相似文献

This study compared the Reform of Secondary Education (ROSE) students’ and nonROSE students’ perceptions of five psychosocial dimensions of their science practical tasks: Student Cohesiveness, Open-Endedness, Integration, Rule Clarity and Material Environment. The sample comprised 177 ROSE and 223 nonROSE Jamaican students, 230 and 170 of them were 8th and 9th graders respectively, 209 were boys and 191 were girls. The Actual Form of Fraser, Giddings and McRobbie’s (1995) Science Laboratory Environment Inventory (SLEI) was adapted and used as an instrument. The results indicated that the students’ perceptions were relatively favourable; ROSE students had significantly better perceptions of Open-Endedness and Material Environment than nonROSE students; the girls had significantly better perceptions of all the dimensions (except Open-Endedness) than the boys; ROSE girls’ and boys’ perceptions of Open-Endedness were significantly better than those of nonROSE students; grades 8 and 9 students’ perceptions were not statistically significantly different.  相似文献

This research addressed the following questions: (1) Which science topic do junior high school students prefer to study—plants or animals? (2) Is their preference related to the variables of grade level and sex of student? Public school students from grades 7, 8, and 9 in Avoca, New York participated in the study. Findings show that 9th grade students have a greater interest in biological science topics than do students in the other grades studied. Girls are more interested in biological science topics than boys are. Girls also showed a significant preference for animals over plants. As a group, junior high school students revealed that they prefer animal study over plant study. About half of the student responses categorized as “biological science” did not express a clear-cut preference for either plants or animals. A caution about generalizability is expressed. Interviews of students suggest that the following characteristics of animals are important determinants of preferences: Animals move, eat, have eyes for sight, communicate by sound, exhibit behaviors that are fun to watch, have short and observable live cycles, interact with humans, can learn, have mates, give birth, and raise their young. It was obvious that most students think of mammals when they hear the term “animal.”  相似文献

For more than half a century concerns about the ability of American students to compete in a global workplace focused policymakers' attention on improving school performance generally, and student achievement in science, technology, engineering, and mathematics (STEM) specifically. In its most recent form—No Child Left Behind—there is evidence this focus led to a repurposing of instructional time to dedicate more attention to tested subjects. While this meant a narrowing of the curriculum to focus on English and mathematics at the elementary level, the effects on high school curricula have been less clear and generally absent from the research literature. In this study, we sought to explore the relationship between school improvement efforts and student achievement in science and thus explore the intersection of school reform and STEM policies. We used school‐level data on state standardized test scores in English and math to identify schools as either improving or declining over three consecutive years. We then compared the science achievement of students from these schools as measured by the ACT Science exams. Our findings from three consecutive cohorts, including thousands of high school students who attended 12th grade in 2008, 2009, and 2010 indicate that students attending improving schools identified by state administered standardized tests generally performed no better on a widely administered college entrance exam with tests in science, math and English. In 2010, students from schools identified as improving in English scored nearly one‐half of a point lower than their peers from declining schools on both the ACT Science and Math exams. We discuss various interpretations and implications of these results and suggest areas for future research. © 2012 Wiley Periodicals, Inc. J Res Sci Teach 49: 804–830, 2012  相似文献

In a technologically driven society, math and science students in the United States are falling further and further behind their international counterparts, resulting in an influx of STEM focused, reformed K-12 schools, including schools focused on project-based learning (PBL). This article reports a study of the effectiveness of PBL on high school students' performance on state mandated standardized mathematics and science achievement measures. Manor New Tech High School is a nationally recognized model STEM school, with a diverse student population, where all instruction is delivered through PBL. Although there is ample research suggesting that PBL is advantageous for increasing STEM learning compared to conventional teaching approaches, there is a lack of studies randomly assigning students to receive PBL. Further, some of the effects observed for students attending project-based schools could be due to a self-selection bias for students or parents that choose such an alternative learning environment. This study addresses both of these concerns and found that students taught through PBL, as a group, matched performance of conventionally taught students on all science 11th grade and mathematics 9th, 10th, and 11th grade TAKS achievement measures and exceeded performance by a scale score increase of 133 for the 10th grade science TAKS measure by (B = 133.082, t = 3.102, p < .05). One possible explanation of the differences observed in this study could be the TAKS instrument used to capture student math and science achievement that interprets “real-life applications” of content differently between math and science questions. These results align with literature on the effects of PBL and deepen our understanding of these effects by providing a controlled study with random assignments to the PBL experience. Future research looking at the effect of PBL on achievement on the PISA could be beneficial in identifying benefits of PBL implementation in schools.  相似文献
