This study examined the effect of a short-term training programme οn in-service physical education teachers’ behaviour and students’ engagement in learning. Teachers (n = 32) were randomly divided into an experimental and a control group. Each teacher’s behaviour was observed in six lessons; two for each measurement (pre, post and retention) and analysed with qualitative dimensions of lesson introduction, task presentations and lesson closure. Student engagement was analysed with the time analysis form. The total and successful attempts of selected students were also recorded. The experimental group attended a two-hour lecture followed by a two-hour practicum, and showed significant improvement and learning of all the examined behaviours as well as significantly higher performance than the control group. Also, students of the experimental teacher group presented significantly greater activity time, more practice attempts and more successful ones than their peers in the control group. The results establish the effect of the training programme on teacher behaviour and student engagement in learning.  相似文献

Following a model on the cyclical nature of teacher (“trait”) self-efficacy and context-, task- and situation-specific (“state”) mastery experiences (TSSME), we investigated the variability and effects of lesson characteristics (e.g. lesson sequence), student group characteristics (e.g. proportion of students receiving free school meals) and teacher characteristics (e.g. teacher experience) on teachers' situation-specific mastery experience. Forty-three teachers reported on 1,055 lessons in 385 student groups using electronic questionnaires in Personal Digital Assistants during a period of 2 weeks. Two domains of TSSME (support of learning and organisation of classrooms) and perception of students (engagement and behaviour) were found. Multilevel models found roughly a quarter of the variance in TSSME between teachers, a quarter between student groups and half between lessons. Student group characteristics differentially predicted TSSME. Perceived student engagement was more predictive of TSSME than perceived student behaviour. More experienced and high-efficacy teachers had higher TSSME. The findings have implications for our understanding of teachers' everyday practice with different student groups.  相似文献

ABSTRACT

To address students’ poor literacy outcomes, an intervention using a computer-based literacy tool, ABRACADABRA, was implemented in 6 Northern Australia primary schools. A pretest, posttest parallel group, single blind multisite randomized controlled trial was conducted with 308 students between the ages of 4 and 8 years old (M age = 5.8 years, SD = 0.8 years). Findings suggested that computer-based instruction under controlled conditions can improve student literacy, especially for Indigenous students at risk of reading difficulties. The authors examine the fidelity with which the computer-based literacy tool was implemented and the impact of implementation fidelity measures on student outcomes. Student exposure to and use of the literacy tool, and quality of instruction and lesson delivery, were analyzed for their influence on students’ literacy outcomes. Implementation fidelity measures accounted for between 1.8% and 15% of the variance of intervention students’ scores.  相似文献

ABSTRACT

A Bayesian IRT-model approach was used to investigate the validity and reliability of student perceptions of teaching quality. Furthermore, the student perceptions were compared with ratings of teaching quality by external observers. Grade 4 students (n = 675) filled out a questionnaire that was used to measure their opinions about the lessons of their teachers. Three lessons of 39 teachers were recorded and rated by 4 raters. The analyses showed that student perception and lesson observation scales fit best in an 11-dimensional model, which was an indication of construct validity and discriminant validity. Student perception scales were reliable, although not all items contributed to the scales to the same extent. Student ratings and lesson observations scores generally correlated moderately (ranging from r = .18 to r = .50). Higher correlations were found for scales with a similar content; however, no clear pattern was apparent. Suggestions for future research are presented.  相似文献

Experiences and reflection have long been regarded as a foundation for pedagogical content knowledge (PCK) development. However, little is known about how experienced teachers develop their PCK via reflection-in-action during their moment-to-moment classroom instruction. Drawing upon data sources including classroom observations, semi-structured interviews and stimulated recall interviews based on lesson videos, this study examined instances when four experienced teachers were found to invent new instructional strategies/representations on the spot during the lesson (referred to as on-site PCK development) in their first attempts at teaching a new topic. The study documented the moment-to-moment experiences of the teachers, including their reconstructed thought processes associated with these instances of on-site PCK development. An explanatory model of a three-step process comprising a stimulus, an integration process and a response was advanced to account for the on-site PCK development observed among the teachers. Three categories of stimulus that triggered on-site PCK development were identified. Factors influencing the integration process and, hence, the resulting response, included teachers’ subject matter knowledge of the new topic, their general pedagogical knowledge and their knowledge of student learning difficulties/prior knowledge related to the new topic. Implications for teacher professional development in terms of how to enhance teachers’ on-site PCK development are discussed.  相似文献

This study investigated gender- and age-related differences in academic motivation and classroom behaviour in adolescents. Eight hundred and fifty-five students (415 girls and 440 boys) aged 11–16 (M age = 13.96, SD = 1.47) filled in a questionnaire that examined student academic motivation and teachers completed a questionnaire reporting student classroom behaviour. Interestingly, early adolescent boys’ (11–12 years) self-reported academic motivation was significantly more closely associated with reports of student classroom behaviour completed by teachers. However, a surprising result was the significant drop in girls’ adaptive motivation from early to mid-adolescence (13–14 years) and a significant increase in mid-adolescence (13–14 years). Furthermore, teachers reported a significant increase in negative classroom behaviour in mid-adolescent and late adolescent girls (15–16 years). The need to further understand the association between academic motivation and classroom behaviour at different stages in adolescence, and to design interventions to improve classroom behaviour, is deliberated.  相似文献

Chemical representations serve as a communication tool not only in exchanges between scientists but also in chemistry lessons. The goals of the present study were to measure the extent of student teachers’ knowledge about chemical representations, focusing on chemical formulae and structures in particular, and to explore which factors related to the education in school and university contribute to inter-individual differences. Using a quantitative cross-sectional design, 322 students from 12 German universities in different stages of their university education were tested with the Chemical Representations Inventory (CRI, Taskin, Bernholt, & Parchmann, 2015). In addition, a short questionnaire was administered containing demographic data and possible factors that could have an effect on students’ success in solving the items of the inventory. The data was analyzed by using Rasch modeling. The results show that student teachers’ knowledge about chemical representations is quite low, with an average of students’ total achievement of 50 % in the corresponding inventory on chemical representations. A multivariate linear model revealed that passing exam(s) in organic chemistry at university, the grade of school leaving certificate, gender as well as studying chemistry in upper secondary school on basic and advanced levels are significant predictors of student teachers’ knowledge. In total, these predictors are able to explain 30.3 % of the variance in the test results. The dominance of school-related variables in the regression analysis indicates that school education seems to be still important after several years of studying and is not equalized by education at university.  相似文献

The purpose of this study was to compare the effects of using two- and three-dimensional model representations of molecular structures on student learning of organic chemical structures. Organic structures were taught to high school students using one of four methods of molecular representation: (1) two-dimensional textbook representations, (2) three-dimensional computer models, (3) three-dimensional ball and stick models, and (4) combination of the computer molecular models and the ball and stick models. The computer software used in this study wasMolecular Editor. Students in the combination group of using both computer and ball and stick models scored significantly higher on the retention test of isomeric identification compared to the other groups. Molecules were represented in this test in the same mode as the instructional representation. However, on a similar two-dimensional post-instructional test of isomeric identification, this group had a significantly lower mean than the other groups; the two-dimensional group had the highest mean. This difference was not observed with the two-dimensional retention test of isomeric identification. When given a two-dimensional test of isomeric construction, no significant difference was found among the group means with either the posttest or the retention test.  相似文献

This paper presents the development and evaluation of a web‐based lesson—Lesson Rainbow. This lesson features multiple representations (MRs), which purposefully deliver concepts in relation to distinctive disciplinary subject areas through story‐based animations that are closely related to learners’ life experiences. The researchers selected 58 2nd‐year junior high school students as the participants (32 males and 26 females). A quasi‐experimental method together with semi‐structured interviews was utilised. This research project was intended to investigate students’ conceptual progress, and to evaluate the use of MRs and of situated learning components in the design of Lesson Rainbow. The statistical results indicated that: (1) students’ science concepts significantly increased (t= 3.84, p < 0.01) through the use of Lesson Rainbow, and (2) students thought that the use of MRs in this web‐based lesson was an effective pedagogical tool inasmuch as it allows for the learning of specific theoretical viewpoints in addition to the necessary background information. Lesson Rainbow employing MRs helps learners to understand the meanings of, and interrelationships between, different kinds of external representations. This kind of design facilitates their understanding of the correspondence between abstract symbolic expressions and real‐world situations.  相似文献

Positive student–teacher relationships are related to students’ academic achievement and behavioural and emotional adjustment. How a student’s behavioural and emotional strengths are associated with these relationships and how the relationships influence students’ academic performance remains unknown. We examined this framework using a cross-lagged panel model with a group of Finnish students and their parents from Grade 5 to Grade 7. The results revealed that the parents rated behavioural and emotional strengths are stable over a 1-year (r = .78) and 2-year (r = .71) period and that students’ perceptions of student–teacher relationships demonstrated greater change over time (r’s = .54, .35). Behavioural and emotional strengths demonstrated a positive relationship with student–teacher relationships as well as academic achievement (β = .39, p < .01). Strengths were also indirectly associated with academic achievement via student–teacher relationships. Study limitations, implications and future research are discussed.  相似文献

Researchers have shown a growing interest in science teachers’ professional knowledge in recent decades. The article focuses on how chemistry teachers impart chemical bonding, one of the most important topics covered in upper secondary school chemistry courses. Chemical bonding is primarily taught using models, which are key for understanding science. However, many studies have determined that the use of models in science education can contribute to students’ difficulties understanding the topic, and that students generally find chemical bonding a challenging topic. The aim of this study is to investigate teachers’ knowledge of teaching chemical bonding. The study focuses on three essential components of pedagogical content knowledge (PCK): (1) the students’ understanding, (2) representations, and (3) instructional strategies. We analyzed lesson plans about chemical bonding generated by 10 chemistry teachers with whom we also conducted semi-structured interviews about their teaching. Our results revealed that the teachers were generally unaware of how the representations of models they used affected student comprehension. The teachers had trouble specifying students’ difficulties in understanding. Moreover, most of the instructional strategies described were generic and insufficient for promoting student understanding. Additionally, the teachers’ rationale for choosing a specific representation or activity was seldom directed at addressing students’ understanding. Our results indicate that both PCK components require improvement, and suggest that the two components should be connected. Implications for the professional development of pre-service and in-service teachers are discussed.  相似文献

ABSTRACT

Context-based learning (CBL) is advocated as beneficial to learners, but more needs to be understood about how different contexts used in courses influence student outcomes. Gilbert defined several models of context that appear to be used in chemistry. In one model that achieves many criteria of student meaning-making, the context is provided by ‘personal mental activity’, meaning that students engage in a role to solve a problem. The model’s predicted outcomes are that students develop and use the specialised language of chemistry, translate what they learn in the immediate context to other contexts, and empathise with the community of practice that is created. The first two of these outcomes were investigated in two large-enrolment university chemistry courses, both organised as this CBL model, in which students were introduced to kinetic molecular theory (KMT). Sample 1 students (N1?=?105) learned KMT through whole-class kinaesthetic activity as a human model of a gas while focusing on a problem identifying substances in balloons filled with different gases. Sample 2 students (N2?=?110) manipulated molecular dynamics simulations while focusing on the problem of reducing atmospheric CO2. Exam answers and pre-/post-test responses, involving a new KMT context, were analysed. Students in Sample 1 demonstrated a stronger understanding of particle trajectories, while Sample 2 students developed more sophisticated mechanistic reasoning and greater fluidity of translation between contexts through increased use of chemists’ specialised language. The relationships of these outcomes to the contexts were examined in consideration of the different curriculum emphases inherent in the contexts.  相似文献

Purpose: To address the dynamic challenges associated with developing a globally sustainable society, numerous scholars have stressed the need to cultivate the imagination of agricultural students. This study aimed to explore how pictorial representations stimulate the imaginative capacities of agricultural extension students. Design/methodology/approach: We adopted a focus group method that enabled in-depth discussions amongst selected participants. Three focus group discussions were held with 15 student participants in Taiwan. Regarding the pictorial representations, a series of works from three great artists were selected, namely Jean-François Millet, Pablo Picasso and Joan Miró. The works were chosen. Findings: The results indicated that different indicators of imaginative capacities were stimulated by different types or combinations of pictorial representations. For example, realistic visual stimuli were beneficial for cultivating student intuition of problem solving. The atmosphere and colour of visual stimuli affected student sensibilities. The abstract stimuli and remote analogues were beneficial in generating original ideas and breaking design fixations. These stimulations occurred largely according to encountering problems and project needs. Practical implications: These findings can assist agricultural educators in developing imaginative curricula and instructional strategies and might increase students’ creative performance. Originality/value: This research provides intriguing insights into the complexities of human imagination. First, the present study developed a novel approach to assess how pictorial representations stimulate the imaginative-capacity indicators of agricultural extension students. Our results indicated that various indicators were stimulated by various types or combinations of pictorial representations, and how and why these stimulations occurred largely depended on design problems and project needs.  相似文献

Teachers play a key role in creating effective conditions for students to succeed in school. The quality of student–teacher relationships is consistently associated with social, emotional, behavioural and academic adjustment, and this is even more relevant for students with special educational needs (SEN), considering these students’ emotional, social and learning vulnerabilities. This study aimed to examine the associations between students’ externalising and internalising behaviour, social skills and academic performance, and teachers’ perceptions of conflict and closeness in their relationships with students with and without SEN. Data regarding 360 students in Year 3, Year 5 and Year 7 (169 students with SEN) were collected. Teachers (n = 74) reported on the student–teacher relationship and students’ social skills, behaviour problems and academic performance. Special education teachers (n = 38) provided information regarding the diagnosis and profile of functioning of students with SEN. Results showed that teachers’ reports of students’ social skills and externalising problems were the strongest predictors of closeness and conflict. Internalising problems and SEN status also predicted decreased closeness, despite smaller effects. Taken together, findings support the importance of professional development opportunities focusing on facilitating teachers’ relationships with students with perceived challenging behaviour.  相似文献

This constructivist study investigates 225 student drawings and explanations from three different schools in the midwest in the US, to identify seventh grade students' mental models of the greenhouse effect. Five distinct mental models were derived from an inductive analysis of the content of the students' drawings and explanations: Model 1, a ‘greenhouse’ for growing plants; Model 2, greenhouse gases cause ozone depletion or formation, causing the Earth to warm; Model 3, greenhouse gases, but no heating mechanism, simply gases in the atmosphere; Model 4, greenhouse gases ‘trap’ the sun's rays, heating the Earth; and Model 5, the sun's rays are ‘bounced’ or reflected back and forth between the Earth's surface and greenhouse gases, heating the Earth. Science textbooks are critiqued in light of the students' mental models and curricular and instructional implications are explored.  相似文献

The study aims to assess the relative importance of a large number of variables for predicting students’ positive-activating emotions during mathematics learning. Participants were 668 first-year upper secondary school students from 33 schools of different sizes and locations. Two questionnaires were distributed, one assessing students’ perceptions and beliefs about their learning situation in mathematics in general, and the other assessing the characteristics of a particular mathematics lesson and the students’ emotional experiences during this lesson. Single-construct and multivariate models for predicting students’ emotions were computed. The results show that the multivariate models were the most efficient, predicting as much as 59 % of the variance in students’ emotional experiences. The two most important constructs were students’ type of motivation and perceived degree of learning, which together predicted 48 % of the students’ emotions. Single-construct models predicted, at most, 36 %. The relative and absolute predictive ability of different motivational constructs are reported. The relationships between constructs and their implications for teaching are discussed.  相似文献

The focus on standardized testing in the areas of reading and mathematics in early elementary education often minimalizes science and the arts in the curriculum. The science topics of health and nutrition were integrated into the reading curriculum through read aloud books. Inclusion of creativity skills through figural transformation drawings allowed students to display nutrition comprehension, modeling how these subject areas can fit into a narrowed curriculum. This repeated measures study examined the weekly effect of teacher lesson introduction on 19 second grade students’ (11 female, 8 male) creativity and content knowledge of nutrition under two conditions that alternated every 2 weeks over a 16-week period: a brief, positive, standard lesson introduction (control) compared to a more enhanced introduction promoting originality, risk-taking and persistence (experimental). Students listened to read-aloud books on nutrition and completed figural transformation drawings related to the stories. Findings showed that student work evidenced more creativity during the experimental condition with a very large effect size for breaking perceived boundaries; a large effect size for depicting movement in drawings; medium effect sizes for fluency, originality, storytelling articulateness, humor, wisdom, emotion, and total creative traits; and a small effect size for elaboration. Students also evidenced greater overall knowledge of health/nutrition content during the experimental condition with a small effect size. Small changes in the way a lesson was introduced had a significant impact on student knowledge and creative performance, indicating that early childhood teachers should implement similar lesson introductions to increase student creativity.  相似文献

The inter-rater reliability of university students’ evaluations of teaching quality was examined with cross-classified multilevel models. Students (N = 480) evaluated lectures and seminars over three years with a standardised evaluation questionnaire, yielding 4224 data points. The total variance of these student evaluations was separated into the variance components of courses, teachers, students and the student/teacher interaction. The substantial variance components of teachers and courses suggest reliability. However, a similar proportion of variance was due to students, and the interaction of students and teachers was the strongest source of variance. Students’ individual perceptions of teaching and the fit of these perceptions with the particular teacher greatly influence their evaluations. This casts some doubt on the validity of student evaluations as indicators of teaching quality and suggests that aggregated evaluation scores should be used with caution.  相似文献

This study examines whether 3 teacher-rated aspects of school effectiveness differ across school segregation profiles in Stockholm, and to what extent these indicators are associated with the academic achievement of 9th-grade students. Analyses were based on 2 cross-sectional data collections performed in 2014 and 2016, respectively (147 school units), one among teachers (n = 2,024) and the other among 9th-grade students (n = 9,151). Multilevel analysis was applied, estimating 2-level random intercept linear regression models. Results show that teachers’ ratings of school leadership, teacher cooperation, and school ethos, as well as student-reported marks differ across school segregation profiles. Findings further reveal significant associations between these school effectiveness indicators and student performance, even when taking student family background and the school’s student body composition into consideration. In part, these associations are also identified within segregation profiles. Moreover, results show that school ethos acts as a mediator between school segregation profile and student achievement.  相似文献
