Abstract

The purpose of this study was to determine if the DISTAR Reading I program was more effective than a basal reading program in increasing school-based language ability. Additionally, I examined the hypothesis that DISTAR develops language more effectively for children who enter school with lower initial language ability than for children with higher language ability, as measured by the Metropolitan Readiness Test. Subjects were 80 Black 1st-grade learners randomly selected from two urban elementary schools. I assessed initial language with the language subtest of the Metropolitan Readiness Test. The adjusted mean score of the DISTAR classes on the posttest of the Slosson Intelligence Test was approximately 9 points higher than the adjusted mean of the basal reader group. Contrary to the second hypothesis, the DISTAR program was equally as effective for students with average or high initial language ability as for students with low initial language ability. The results are discussed as support for the proposition that the use of DISTAR direct-instruction procedures is a successful means of developing school-based language.  相似文献

Being a teacher requires the ability to work with difficult behaviors—not just of students and parents but also of colleagues. Preservice teachers need the opportunity to develop and practice collaboration and communication skills in school settings. This essay draws on research from organizational psychology to offer a framework for understanding challenges to workplace collaboration in school settings and strategies for developing these skills in preservice teachers.  相似文献

The aim of the present study is to explore the effects of Meta‐strategic Knowledge (MSK) on scientific inquiry learning. MSK is a subcomponent of metacognition defined as general, explicit knowledge about thinking strategies. Following earlier studies that showed considerable effects of explicit instruction of MSK regarding the strategy of variables control, the present study explores whether similar effects are found in two additional scientific thinking strategies: Define Research Questions and Formulate Research Hypotheses. Participants were 119 eighth‐grade students from six classes of a heterogeneous school. Equal numbers of low‐achieving and high‐achieving students were randomly assigned into experimental and control groups. The findings showed dramatic developments in students’ performance following instruction. The effect of the treatment was preserved in a delayed transfer test. Our findings show that explicit teaching of MSK had a stronger effect for low‐achieving students than for high‐achieving students. The implications of the findings for teaching and learning in the context of scientific inquiry are discussed.  相似文献

This quasi‐experimental study investigates how the classroom learning environment changed after inquiry‐based activities were introduced and student questioning was encouraged. Three science teachers and three classes of fifth graders (n=92) participated in this study. The analysis of covariance reveals that although the experimental group students perceived that their teacher’s support was significantly lower than that for the comparison group did (p< 0.05), they were significantly more involved in learning (p< 0.05) than their counterparts. Classroom observations of student questioning and inquiry activities revealed that those students with high quality levels in asking or responding to questions outperformed their counterparts in the inquiry ability of designing experimental procedures.  相似文献

This study explored the effects of congruency between preferred and actual learning environment (PLE & ALE) perceptions on students’ science literacy in terms of science concepts, attitudes toward science, and the understanding of the nature of science in an innovative curriculum of High Scope Project, namely Sci-Tech Mind and Humane Heart (STMHH). A pre-/post-treatment experiment was conducted with 34 Taiwanese tenth graders involved in this study. Participating students’ preferred learning environment perception and pre-instruction scientific literacy were evaluated before the STMHH curriculum. Their perceptions toward the actual STMHH learning environment and post-instruction scientific literacy were also examined after the STMHH. Students were categorized into two groups; “preferred alignment with actual learning environment” (PAA) and “preferred discordant with actual learning environment” (PDA), according to their PLEI and ALEI scores. The results of this study revealed that most of the students in this study preferred learning in a classroom environment where student-centered and teacher-centered learning environments coexisted. Furthermore, the ANCOVA analysis showed marginally statistically significant difference between groups in terms of students’ post-test scores on scientific literacy with the students’ pre-test scores as the covariate. As a pilot study with a small sample size aiming to probe the research direction of this problem, the result of marginally statistically significant and approaching large sized effect magnitude is likely to implicate that the congruency between preferred and actual learning environments on students’ scientific literacy is noteworthy. Future study of this nature appears to merit further replications and investigations.  相似文献

Rooted in science education and science communication studies, this study examines 4th and 5th grade students’ perceptions of science information sources (SIS) and their use in communicating science to students. It combines situated learning theory with uses and gratifications theory in a qualitative phenomenological analysis. Data were gathered through classroom observations and interviews in four Turkish elementary schools. Focus group interviews with 47 students and individual interviews with 17 teachers and 10 parents were conducted. Participants identified a wide range of SIS, including TV, magazines, newspapers, internet, peers, teachers, families, science centers/museums, science exhibitions, textbooks, science books, and science camps. Students reported using various SIS in school-based and non-school contexts to satisfy their cognitive, affective, personal, and social integrative needs. SIS were used for science courses, homework/project assignments, examination/test preparations, and individual science-related research. Students assessed SIS in terms of the perceived accessibility of the sources, the quality of the content, and the content presentation. In particular, some sources such as teachers, families, TV, science magazines, textbooks, and science centers/museums (“directive sources”) predictably led students to other sources such as teachers, families, internet, and science books (“directed sources”). A small number of sources crossed context boundaries, being useful in both school and out. Results shed light on the connection between science education and science communication in terms of promoting science learning.  相似文献

This study measured and explored the relationships among elementary mathematics teachers’ skill in (a) determining what an item measures, (b) analyzing student work, (c) providing targeted feedback, and (d) determining next instructional steps. Twenty-three elementary mathematics teachers were randomly assigned to one of three conditions: analyzing items and student responses without rubrics, analyzing items and student responses with rubrics, or analyzing items and student responses with rubrics after watching a professional development program on providing feedback to students. Findings show there is a moderate to strong relationship between teachers’ abilities to analyze student responses to infer what a student knows and can do and their abilities to take action based on that information through either providing the student feedback or making appropriate instructional adaptations. Findings show it was relatively more difficult for teachers to provide feedback that was likely to move students forward in their learning than it was for them to analyze a student's response or to determine next instructional steps. No teacher skill differences associated with the different treatment conditions were found.  相似文献

We report on a study investigating the relationship between cognitive ability grouping, reflective inquiry scaffolding, and students’ collaborative explanations of an ecosystem disturbance which took place when a number of flamingo birds died in a salt lake because of nearby intensive human activities. Twenty-six pairs of students from two intact sixth-grade classes participated in the study. All students investigated scientific data relating to the ecosystem problem using a web-based learning environment. One class was provided with web-based reflective inquiry scaffolding (WorkSpace), while the other class used PowerPoint. The main data analyzed for this study consisted of each pair’s written explanation and task-related artifacts. Findings show that the web-based reflective scaffolding supported students in providing valid evidence in support of their explanations. The analyses of the students’ collaborative explanations showed no statistically significant differences that could be attributed to prior achievement between students in the WorkSpace condition, while differences were found between the different cognitive ability pairs in the PowerPoint class. These findings suggest that the WorkSpace scaffolding may have provided more influential support to lower cognitive ability pairs in creating evidence-based explanations.  相似文献

The purpose of this research was to look for possible benefits and drawbacks of the use of computer‐supported simulation in the teaching and learning of experimental research methodology and statistics. In the study three research methodology groups were compared. The results show that there were significant differences in favour of the computer‐supported simulation group, called the ALEL group. During the course the conversations of two students' in the ALEL group were audiotaped. Although the ALEL students performed better than the other students and showed an improvement during the course, the conversations analysed showed that their learning outcomes should be still better in order to meet the learning goals of the methodology and statistics curriculum. An inadequate knowledge base was shown in the post‐test and also in the discussions of the pair during the course.  相似文献

In recent years, unequal access to high-quality preschool has emerged as a growing public policy concern. Because of data limitations, it is notoriously difficult to measure disparities in access to early learning opportunities across communities and particularly challenging to quantify gaps in access to high-quality programs. Research Findings: Using unique data from Georgia’s universal prekindergarten program, this study provides empirical evidence of the relationship between community characteristics and the availability of high-quality preschool opportunities. We show that in Georgia, a national leader with respect to preschool access as well as quality, there are still meaningful differences in quality across communities. Low-income and high-minority communities offer state preschool classrooms that are rated significantly lower on a widely used and validated measure of classroom process quality. Practice or Policy: This process quality gap is troubling given the positive relationship between our process quality measure and children’s learning. Note that we do not see similar gaps in structural measures of quality, which are the aspects of quality more often regulated but are also weaker, inconsistent predictors of children’s learning. Implications for policy are discussed.  相似文献

Little change has been noted over 10 years of research into teacher knowledge and confidence to teach science in the early and primary years of schooling. There is a significant body of research demonstrating that early childhood and primary teachers lack confidence and competence in teaching science. However, much of this research blames the victim, and offers little analysis for the systemic reasons for teachers’ confidence and competence in science education other than a lack of science knowledge. This paper reports on a study that examined teacher philosophy and pedagogical practices within the context of an analysis of children’s concept formation within playful early childhood settings. Through teacher interviews, video recordings of science play, and photographic documentation of children’s science activities in one rural preschool, it was noted that teacher philosophy about how young children learn is a significant contributing factor to learning in science. It is argued that teacher philosophy makes more of a difference to children’s scientific learning than does teacher confidence to teach science or knowledge of science. The study also shows that without a mediational scientific framework for using materials in play‐based contexts, children will generate their own imaginary, often non‐scientific, narratives for making sense of the materials provided.  相似文献

This study explored relationships between characteristics of classroom talk exposure and immigrant first graders' acquisition of second language oral skills (vocabulary and listening comprehension) and literacy skills. Twenty‐six children (mean age = 6.10 years) with Turkish as their first language and Norwegian as their second, attending various multilingual and ethnically diverse classrooms in Norway, were videotaped during classroom conversations. Classroom talk was coded for vocabulary richness, discursive complexity and emergent phonics talk and the children's oral language and literacy skills were assessed. Classroom vocabulary richness and discursive complexity predicted the children's second language vocabulary skills and listening comprehension after controlling for maternal education, but did not predict their literacy skills. The density of emergent phonics talk did not predict target children's code‐related skills in this sample. Applied perspectives related to second language learning in multiparty settings are discussed.  相似文献

Schon (1987) has criticized the normative curriculum of professional schools including technical colleges: at first basic science (mathematics, physics, etc.), then applied science, and finally technical skills of day‐to‐day practice. In Schön's opinion, the tradition of professional education is an obstacle to changing teaching methods from drill and practice to open‐learning environments. Solomon (1986) presents the different approaches which teachers take in computer‐based instruction in stages from drill and practice to open‐learning environments. This paper reports a six‐year case study, inspired by the work of Schön and Solomon, on the impact of, and the teachers’ role in, the use of computers and Mathcad in the mathematics instruction of technical colleges. The teaching experiment was started with 51 first‐year students during the academic year 1988‐1989 at the Technical Institute of Jyvaskyld. The class of mechanical engineering had 162 and the class of electrical engineering 206 lessons of mathematics during the first experimental year. Two senior lecturers of mathematics taught the classes. Before the experiment, computers had never been used in mathematics instruction at the institute. The various ways of using Mathcad were classified on the basis of the forms filled and files saved by the teachers, as well as on the notes made by the researcher. The teachers’ ways of using computers in our experiment during the years 1988‐1995 clearly showed the existence of stages. Some of the stages were the same for both teachers, but there were also some differences. Both teachers started by fitting an open computer‐based environment into the traditional instruction.  相似文献

Studies have shown that there is a need for pedagogical content knowledge among science teachers. This study investigates two primary teachers and their objectives in choosing inquiry- and context-based instructional strategies as well as the relation between the choice of instructional strategies and the teachers’ knowledge about of students’ understanding and intended learning outcomes. Content representations created by the teachers and students’ experiences of the enacted teaching served as foundations for the teachers’ reflections during interviews. Data from the interviews were analyzed in terms of the intended, enacted, and experienced purposes of the teaching and, finally, as the relation between intended, enacted, and experienced purposes. Students’ experiences of the teaching were captured through a questionnaire, which was analyzed inductively, using content analysis. The results show that the teachers’ intended teaching objectives were that students would learn about water. During the enacted teaching, it seemed as if the inquiry process was in focus and this was also how many of the students experienced the objectives of the activities. There was a gap between the intended and experienced objectives. Hardly any relation was found between the teachers’ choice of instructional strategies and their knowledge about students’ understanding, with the exception that the teacher who also added drama wanted to support her students’ understanding of the states of water.  相似文献

This paper reports on a teacher’s and his students’ responsiveness to a new tetrahedral-oriented (Mahaffy in J Chem Educ 83(1):49–55, 2006) curriculum requiring more discursive classroom practices in the teaching of chemistry. In this instrumental case study, we identify the intentions of this learner-centered curriculum and a teacher’s development in response to this curriculum. We also explore the tensions this teacher experiences as students subsequently respond to his adjusted teaching. We use a Chemistry Teacher Inventory (Lewthwaite and Wiebe in Res Sci Educ 40(11):667-689, 2011; Lewthwaite and Wiebe in Can J Math Sci Technol Educ 12(1):36–61, 2012; Lewthwaite in Chem Educ Res Pract. doi:10.1039/C3RP00122A, 2014) to assist the teacher in monitoring how he teaches and how he would like to improve his teaching. We also use a student form of the instrument, the Chemistry Classroom Inventory and Classroom Observation Protocol (Lewthwaite and Wiebe 2011) to verify the teacher’s teaching and perception of student preferences for his teaching especially in terms of the discursive processes the curriculum encourages. By so doing, the teacher is able to use both sets of data as a foundation for critical reflection and work towards resolution of the incongruence in data arising from students’ preferred learning orientations and his teaching aspirations. Implications of this study in regards to the authority of students’ voice in triggering teachers’ pedagogical change and the adjustments in ‘teachering’ and ‘studenting’ required by such curricula are considered.  相似文献

This paper synthesizes findings from three studies to answer a general question: What do casual, adult visitors learn about science from their science‐related experiences in free‐choice settings? Specifically we asked whether there are changes in how people think about science in their daily lives, the nature and use of scientific knowledge, and its communication by scientists. The three studies involved samples of visitors to an interactive science centre, visitors to a traditional natural history museum, and attendees at a series of public lectures, each given by an expert scientist in human genetics. Pretest and post‐test data collected by parallel questionnaires indicated that, despite the different nature of their experience in the three different settings, participants became more positive about the value of science and the work done by scientists and their ability to communicate with the public. At all venues, however, participants became less scientific in their thinking about the nature of scientific knowledge, becoming more likely to believe it to be infallible. The consistency of these findings was surprising, and participants’ changed views about the nature of scientific knowledge were unexpected. Possible explanations for theses outcomes were suggested in terms of participants’ reasons for attending the venue, the nature of their engagement, and the non‐controversial ways in which the exhibitions and lectures were structured. The findings suggest that the educational role of free‐choice settings should be considered carefully, particularly with regard to the representation of science.  相似文献

For an educational reform to succeed, teachers need to adjust their perceptions to the reform’s new curricula and strategies and cope with new content, as well as new teaching and assessment strategies. Developing students’ scientific literacy through context-based chemistry and higher order thinking skills was the framework for establishing a new chemistry curriculum for Israeli high school students. As part of this endeavor, we developed the Taste of Chemistry module, which focuses on context-based chemistry, chemical understanding, and higher order thinking skills. Our research objectives were (a) to identify the challenges and difficulties chemistry teachers faced, as well as the advantages they found, while teaching and assessing the Taste of Chemistry module; and (b) to investigate how they coped with teaching and assessing thinking skills that include analyzing data from graphs and tables, transferring between multiple representations and, transferring between chemistry understanding levels. Research participants included eight teachers who taught the module. Research tools included interviews, classroom observations, teachers-designed students’ assignments, and developers-designed students’ assignments. We documented different challenges teachers had faced while teaching the module and found that the teachers developed different ways of coping with these challenges. Developing teachers’ assessment knowledge (AK) was found to be the highest stage in teachers’ professional growth, building on teachers’ content knowledge (CK), pedagogy knowledge (PK), and pedagogical-content knowledge (PCK). We propose the use of assignments designed by teachers as an instrument for determining their professional growth.  相似文献
