In research on the nature of science, there is a need to investigate the role and status of different scientific knowledge forms. Theories and models are two of the most important knowledge forms within biology and are the focus of this study. During interviews, preservice biology teachers (N = 10) were asked about their understanding of theories and models. They were requested to give reasons why they see theories and models as either tentative or certain constructs. Their conceptions were then compared to philosophers’ positions (e.g., Popper, Giere). A category system was developed from the qualitative content analysis of the interviews. These categories include 16 conceptions for theories (n tentative = 11; n certain = 5) and 18 conceptions for models (n tentative = 10; n certain = 8). The analysis of the interviews showed that the preservice teachers gave reasons for the tentativeness or certainty of theories and models either due to their understanding of the terms or due to their understanding of the generation or evaluation of theories and models. Therefore, a variety of different terminology, from different sources, should be used in learning-teaching situations. Additionally, an understanding of which processes lead to the generation, evaluation, and refinement or rejection of theories and models should be discussed with preservice teachers. Within philosophy of science, there has been a shift from theories to models. This should be transferred to educational contexts by firstly highlighting the role of models and also their connections to theories. 相似文献

The current intervention study investigated the sustained effectiveness of phonological awareness training on the reading development of 16 children in French immersion who were identified as at-risk readers based on grade 1 English measures. The intervention program provided children from three cohorts with supplemental reading in small groups on a withdrawal basis. Children in the experimental group (n = 5) received English phonological awareness training in combination with letter-sound correspondence instruction twice per week for 18 consecutive weeks, while those in the control condition (n = 7) engaged in English vocabulary-building activities. Significant gains were made after the training and maintained for 2 years on both French phonological awareness and French word reading skills for the experimental group. Results suggest that a phonologically based intervention in English can effectively address phonological awareness deficits and facilitate reading acquisition for French immersion children who may be at-risk for later reading difficulties. 相似文献

Studies have shown that children benefit from a spelling pronunciation strategy in remembering the spellings of words. The current study determined whether this strategy also helps adults learn to spell commonly misspelled words. Participants were native English speaking college students (N = 42), mean age 22.5 years (SD = 7.87). An experimental design with random assignment, pretests, training, and posttests assessed effects of the pronunciation strategy on memory for the spellings of 20 hard to spell words. Half of the participants were trained to read the words by assigning spelling pronunciations during learning (n = 21). The comparison group (n = 21) practiced reading the words normally without the strategy. Strategy trained adults recalled significantly more words, total letters, silent letters, and schwa vowel letters correctly than controls. Poor spellers benefited as much if not more from this strategy as good spellers. Results support orthographic mapping theories. Optimizing the match between spelling units and sound units, including graphemes and phonemes, syllables, and morphemes, to create spelling pronunciations when words are read enhances memory for spellings of the words. As a result, higher quality lexical representations are retained in memory. Results suggest the value of teaching college students this strategy to improve their ability to spell words correctly in their written work. 相似文献

Beginning readers in shallow orthographies acquire word reading skills more quickly than in deep orthographies like English. In addition to extending this evidence base by comparing reading acquisition in English with the more transparent German, we conducted a longitudinal study and investigated whether different early reading skills made different contributions to word reading as a function of orthography. Children (n = 133) were recruited from the first year of primary school in New Zealand (age 5;8) and Germany (age 7;2) and from kindergartens in Germany (age 5;0) to provide both age- and schooling-matched samples. Parallel measures of phonemic awareness, vocabulary, decoding skill, and word reading (accuracy) were administered at two time points, 1 year apart. An advantage for orthography and school attendance existed for reading development. Vocabulary made a greater contribution to word reading in English than in German as did decoding skill. Findings underscore the relative importance of vocabulary and decoding skills for early reading in English. 相似文献

For 2 years we followed lower-performing English learner (EL) and native English speaking (non-EL) students who participated in an efficacy trial of a supplemental first-grade code-oriented intervention implemented by paraeducators. At the end of grade three, across all students (n = 180 of the original 187 students), treatment effects were maintained on word reading (approximate d = .45), spelling (.36) and reading comprehension (.24). However, treatment effects tended to be smaller for EL students, and were significantly smaller for spelling in particular. While pretest grade one word reading did not moderate treatment response for either ELs or non-ELs, it was found to strongly predict all three end-of- grade-three outcomes, although to a lesser extent for ELs on reading comprehension. Findings add support to previous research on the benefits of early code-oriented tutoring. 相似文献

This study investigated the use of a wiki for collaborative writing among primary levels five (P5) and six (P6) students (n = 119) in a Chinese primary school in Hong Kong where English is taught as a second language (L2). Three classes of students and their English subject teachers participated in a three-month English language writing programme using a wiki. Quantitative and qualitative data were analyzed from activities recorded in the wiki system, including posted edits and comments, students’ group writings and student and teacher interviews. The wiki page history revealed information on the types of revisions that occurred, showing that different types of feedback elicited actual revisions, which may have resulted in better group writing. Findings from the study may shed light on how wikis can help provide support for students’ collaborative writing process with wikis, and how peer-feedback can influence this process. 相似文献

The current study examined the contribution of cross-language phonological and morphological awareness to reading acquisition in bilingual children. Participants were 140 children (M age = 8.26 years) between Grades 1–4 who learned Chinese as their first language and English as their second language. Awareness of phoneme, onset-rime, compound structures and polysemy (i.e. words with multiple meanings) were measured using conceptually comparable tasks in both languages. Oral vocabulary, single word reading, and reading comprehension were also assessed. Path analysis revealed significant direct effects from Chinese rime awareness to both English word reading and reading comprehension. English phoneme awareness also had a significant direct effect on Chinese word reading. There was a significant direct effect from Chinese polyseme identification to English reading comprehension. Awareness of compound structure in one language also had indirect effects on reading outcomes in the other language via within-language compound structure awareness. These finding provided evidence for bi-directional cross-language phonological and morphological transfer in Chinese–English bilingual reading acquisition. 相似文献

Peer assessment has been widely applied to actively engage students in learning to write. However, sometimes students resist peer assessment. This study explores reviewers’ attitudes and other underlying factors that influence students’ participation in online peer assessment. Participants were 234 Chinese undergraduates from two different academic backgrounds: engineering majors (n = 168) and English majors (n = 66). Gender, academic background and prior experience with peer assessment were all related to participation levels. Moreover, factor analyses revealed three attitudinal factors: (1) positive attitude (a general endorsement of the benefits of peer assessment), (2) interpersonal negative (concerns about the negative effects on interpersonal relationships), and (3) procedural negative (doubts about the procedural rationality of peer assessment). Among the attitudinal factors, procedural negative was negatively associated with participation, as expected. Interestingly, interpersonal negative was associated with greater participation, and positive attitude was associated with lower participation, in part because students worked hard on each review rather than doing many reviews superficially. Implications for instruction are discussed. 相似文献

This article examines the effects of changing teacher self-efficacy on student achievement. Results from a quantitative study of mathematics teachers in a USA mid-Atlantic state showed that teachers experienced reduced self-efficacy when working with English language learner students (ELLs) relative to non-ELLs. Further, the article explores professional development opportunities for strengthening teachers’ effectiveness with ELLs. The study utilized a four-part survey instrument based on the Teacher Sense of Efficacy Scale (TSES). All participants (n = 181) were mathematics educators from the highlighted state, and 94 % of them were preK-12 public school practicing classroom teachers. Study results indicate that teachers’ participation in professional development on ELL instruction is positively correlated to their heightened sense of self-efficacy. This finding points to continuing education as a potentially viable approach to reducing academic challenges for ELL students in mainstream mathematics classrooms by developing ever more effective practicing teachers. 相似文献

For nearly 50 years, leaders in American industry, military, education, and politics have focused considerable attention on STEM (science, technology, engineering, and mathematics) education. Given the increased societal demand for STEM careers, the relationships among classroom climate, self-efficacy, and achievement in undergraduate mathematics needed to be examined. A purposeful sample of college algebra instructors (n = 15), employed at public 4-year universities in various states (n = 10) across the nation, was administered the Principles of Adult Learning Scale at the beginning of the semester to assess classroom climate. At the end of the course semester, their college algebra students (n = 326) were administered the Mathematics Self-Efficacy Scale-Revised and final college algebra examinations. The results of the multi-level analysis indicated: (a) students having higher mathematics self-efficacy also had higher mathematics achievement, (b) teacher-centered classroom climates had greater mathematics self-efficacy levels, (c) classroom climate was not a significant predictor of mathematics achievement, (c) classroom climate did not moderate the relationship between mathematics self-efficacy and achievement, and (d) although boys reported higher mathematics self-efficacy than girls, gender differences were not found to exist in regard to mathematics achievement. 相似文献

Although research recognizes that student attitudes toward writing have the potential to influence a variety of writing outcomes, there is no consensus as to what writing attitude signifies. Further, disparities between conceptualizations of writing attitude make the extant literature difficult to reconcile. In the present study, we systematically review writing attitude research published between 1990 and 2017. Our search procedure and quality analysis led to the retention of 46 articles examining the writing attitudes of students and teachers. Relatively few studies (n = 10) provided an explicit definition of writing attitudes. Further, although the authors of many studies (n = 16) conceptualized writing attitude as including a measure of liking/disliking writing, there was considerable variability in both conceptualization and operationalization throughout the literature, with some studies including measures of self-efficacy, perceived value, and other related constructs. Student writing attitudes were measured in a majority of the included studies (n = 33), and teacher writing attitudes were measured in substantially fewer studies (n = 6). Based on the findings of this review, we offer suggestions for researchers making inferences from studies of writing attitudes. Themes of the reviewed literature and implications for future research are also discussed. 相似文献

There are a number of individual and affective factors which correlate foreign language learners’ achievement both positively and negatively. The aim of this study was to examine the relationship between perfectionism and English language achievement among high school third graders in Chenaran, a city in northeast of Iran, mediated by foreign language classroom anxiety. A sample of 239 students (110 males and 129 females) was assessed for their levels of perfectionism and foreign language anxiety using the Almost Perfect Scale-Revised and Foreign Language Classroom Anxiety Scale, respectively. Participants’ scores on their final English test were also used as the measurement of their English achievement. The results did not reveal strong correlations between perfectionism and participants’ English achievement (F = .515, p > .05); however, the mean English score of the participants was lower for maladaptive perfectionists. Also, foreign language classroom anxiety was found to be significantly and negatively correlated with English achievement (r = ?.357, p < .01). The results of analysis of variance revealed a significant positive association between perfectionism and foreign language anxiety, where maladaptive perfectionists were found to be more anxious than adaptive and non-perfectionists. Results did not support the hypothesis about foreign language anxiety as a mediator of the relationship between perfectionism and English achievement. Implications for both teachers and learners, and suggestions for further research are provided. 相似文献

This study examines the contribution of learner cognitive and motivational characteristics to achievement in science at three grade levels. Specifically, the relations between domain-specific epistemic beliefs about the development and justification of scientific knowledge, achievement goals, knowledge, self-concept, self-efficacy, and achievement in science were simultaneously examined. Students in fifth (n = 213), eighth (n = 202), and eleventh (n = 281) grades completed questionnaires measuring the various constructs, and a domain knowledge test. Their grades in science were also collected. Results from structural equation modeling reveal that the hypothesized model fitted the observed data at the three grade levels, although not all expected paths were statistically significant. Students’ epistemic beliefs about the development of scientific knowledge had a direct effect on domain knowledge, whereas beliefs about the justification of scientific knowledge had a direct and an indirect effect via achievement goals on knowledge acquisition. Mastery, performance-approach, and performance-avoidance goals had a direct effect on self-efficacy. Knowledge had a direct and an indirect effect via self-concept on achievement. Educational implications are discussed. 相似文献

This paper summarizes how collaborative online projects (COPs) are used to facilitate science content-area learning for English Learners of Hispanic origin. This is a Mexico-USA partnership project funded by the National Science Foundation. A COP is a 10-week thematic science unit, completely online, and bilingual (Spanish and English) designed to provide collaborative learning experiences with culturally and linguistically relevant science instruction in an interactive and multimodal learning environment. Units are integrated with explicit instructional lessons that include: (a) hands-on and laboratory activities, (b) interactive materials and interactive games with immediate feedback, (c) animated video tutorials, (d) discussion forums where students exchange scientific learning across classrooms in the USA and in Mexico, and (e) summative and formative assessments. Thematic units have been aligned to U.S. National Science Education Standards and are under current revisions for alignment to the Common Core State Standards. Training materials for the teachers have been integrated into the project website to facilitate self-paced and independent learning. Preliminary findings of our pre-experimental study with a sample of 53 students (81 % ELs), distributed across three different groups, resulted in a 21 % statistically significant points increase from pretest to posttest assessments of science content learning, t(52) = 11.07, p = .000. 相似文献

Understanding academic vocabulary is essential to student success in school. Use of academic vocabulary words in writing is considered one of the strongest measures of how well a reader understands a given word. In theory, willingness to use academic vocabulary in writing indicates the complexity of acquiring representations of the word’s orthography, phonology, and semantics based on the word’s characteristics. In addition, a learner’s overall literacy skills should relate to whether they attempt to use words. In the present study, sixth graders (n = 66), seventh graders (n = 60), and eighth graders (n = 41) learned 25 academic vocabulary words in a supplementary academic vocabulary intervention and were then asked to use those words in short persuasive essay drafts. We measured whether these students attempted to use a word (a binary uses outcome) and the number of times a student used a word (a continuous attempts outcome) and used cross-classified random effects models to examine how (a) the orthographic, phonological, and semantic characteristics of words and (b) the students’ literacy-related characteristics related to their uses and attempts. For word characteristics, students were more likely to use and attempt high frequency than low frequency words. For student characteristics, students proficient on the state exam were more likely to use and attempt the words, and students learning English were less likely to attempt the words. Implications for vocabulary intervention and writing instruction are discussed. 相似文献

The present educational design research involved analysing Finnish upper secondary school students’ participation in the improvement of their psychosocial and technology-enhanced physical learning environment (LE). It examined which LE characteristics students considered important when redesigning their LE, and whether they felt that their ideas for improvement had been taken into account in the LE change process and if there was an improvement in these characteristics. A Learning Environment Design (LED) framework balancing the various LE dimensions, namely, communality and individuality, comfort and health, novelty and conventionality, was utilised in the analysis for four sets of data collected for four cycles: (a) co-design activities (students, n = 11) and (b) student feedback (n = 175); (c) professional design evaluation (students, n = 2); and (d) student satisfaction survey (n = 83). Students considered all LE dimensions important. In addition, they felt that their wishes were generally taken into account in the redesign and also they perceived an improvement in most of the LE characteristics. Student involvement helped to avoid overly radical changes, fostered a participatory culture, and contributed to understanding what students view as important to their learning and wellbeing. The study demonstrated the usefulness of the LED-framework for LE design and suggests content-related design principles to serve as a starting point in LE improvement projects involving learners. 相似文献

Researchers state that teachers in different contexts reported different technological pedagogical content knowledge (TPACK). This phenomenon may partially be explained by cultural differences. Based on this consideration, the development and validation of the Chinese pre-service teachers’ technological pedagogical content knowledge (CTPCK) scale is described in this article. The sample was split into two subsamples on random basis (n1 = 229, n2 = 207) for the purpose of conducting (1) exploratory factor analysis (EFA) and (2) confirmatory factor analysis (CFA), respectively. After the EFA, the CTPCK scale excluded six items and included eight factors with 42 items. Reliability and correlations were discussed. The findings revealed that the CTPCK scale was a valid and reliable instrument for measuring the TPACK of Chinese pre-service teachers’ knowledge with or without linking educational technology. 相似文献

Argumentation skills play a crucial role in science education and in preparing school students to act as informed citizens. While processing conflicting scientific positions regarding topics such as sustainable development in the domain of ecology, argumentation skills such as evaluating arguments or supporting theories with evidence are beneficial for developing deep understanding and well-grounded conclusions. We developed a 50-min training intervention to foster argumentation skills in the domain of ecology on topics related to sustainable development and analyzed its effects in a control-group design: (a) training intervention to foster argumentation skills (n = 41), (b) no such training intervention (n = 42). Results showed that this short-term training intervention successfully fostered three components of argumentation skills (i.e., evaluative knowledge, generative knowledge, and argument quality) and declarative knowledge about argumentation. The positive effect on declarative knowledge was stable 1 week after the training and it was mediated by learning processes during the training intervention: self-explaining the principles of argumentation underlying the video-based examples mediated the effect on declarative knowledge 1 week after the training. In short, the training intervention is an effective instructional method to enhance argumentation skills as well as declarative knowledge about argumentation. 相似文献

The current study examined the effects of stress and campus climate perceptions on the persistence decisions of students of color and White students using Bean and Eaton’s (2000) Psychological Model of College Student Retention. A sample of first-year students (N = 1,491) at a predominantly White research university were survey enduring their second semester and their enrollment status was subsequently tracked after 2 years. Path analysis was conducted on the sample of students of color (n = 548) and White students (n = 943). Results indicated models that explained 27 % of the variance for students of color and 44 % of the variance for White students in persistence after 2 years of college. Among the initial 37 variables included in the models, 17 had significant direct and indirect effects on students’ of color persistence including observing racism on campus, having comfortable academic interactions, stress related to the academic environment, and feelings about the campus environment. For White students, 13 variables had significant direct and indirect effects on persistence, including having opportunities for diverse peer interactions and comfortable academic interactions, stress related to the social environment on campus, and feelings about the campus environment. The discussion highlights the usefulness of the Bean and Eaton model for examining retention for students of color and White students. 相似文献
