Purpose: This qualitative case study investigates a primary science teacher’s TPACK development in the context of two interdependent learning spaces: a joint-school and a within-school professional learning community. The school’s organizational and sociocultural influences on teacher learning are also examined.
Participant: Teacher Sean (pseudonym) embarked on a science innovation project after two years of teaching in a Singapore mainstream school. He was tasked to integrate mobile-based inquiry learning and visible thinking pedagogical approaches, and to pilot the designed lessons for a primary three class.
Design and methods: A case-study approach involving multiple sources of data with cultural historical activity theory as the analytical lens was employed, to unpack the complementary and contradictory interactions across different interrelated activity systems. The purpose was to understand the (mis)alignments within and between the two professional learning communities.
Results: The findings indicate that Sean’s (subject) learning from the joint-school professional learning community to the within-school professional learning community faced multiple tensions that hindered his TPACK development (object). He faced difficulty in manipulating tools (technology and visible thinking routines) to translate the joint-school co-designed lessons into classroom implementation. Additionally, the volatility of the school’s organizational routines (rules) and the lack of communicative leader–teacher partnership (division of labor) did not afford sufficient infrastructure or instructional support.
Conclusions: Interactions between the teacher’s personal and contextual factors inhibited the designed TPACK from being implemented successfully. For ambitious pedagogical undertakings as illustrated in this case, more perceptive and synergistic organizational design thinking is needed to support beginning teachers’ TPACK development. 相似文献
Objective: This study aimed at testing a hypothesized model of achievement in CS in terms of the learner and the learning environment characteristics.
Method: Data were collected using a questionnaire administered to a random sample of 315 eleventh and twelfth-grade advanced CS students (28% girls). Structural equation modelling (SEM) analysis was utilized to test the proposed structural model.
Findings: The hypothesized structural model fits the data reasonably, yet five of the 17 assumed effects were not significant. A modified model with only significant effects fit the data well and accounted for 41% of the variance. Mathematics achievement, self-efficacy and classroom learning environment are the most influential variables on achievement in CS.
Implications: The findings bear important implication for helping students by resolving obstacles that obstruct their learning and achievement. 相似文献
Purpose: This study examined Grades 5 and 9 students’ views of uncertainty in their personal scientific research and the formal scientific research of professionals.
Sample: This study included 33 students in Grade 5 (n = 17) and Grade 9 (n = 16). The students were recruited from a charter school that emphasised inquiry instruction.
Design and methods: Data were collected through interviews. Students were asked their views of their inquiry-based projects and their views of professional science.
Results: Interview data and statistical analyses indicated that students recognized uncertainty in personal science, which varied across elements of the scientific process. Additionally, their views of uncertainty in formal science tended to change across grades and knowledge of uncertainty in personal and formal science were positively correlated.
Conclusion: These findings offer insights into the processes by which students come to understand uncertainty in science and point to ways of fostering such knowledge through teaching practices. 相似文献
Purpose: The purpose of this research is to examine both the direct and indirect relationships between the inquiry-based self-efficacy, the achievement goal orientation, the learning strategies, and the inquiry skills variables.
Sample: This research was conducted during the 2015-2016 school year among 498 seventh and eighth graders at public schools in Turkey’s Ayd?n province.
Design and methods: The Inquiry-based Self-Efficacy Scale, the Goal Orientation Scale, the Learning Approach Scale, and the Inquiry Skills Test were applied to the students. The analysis of data was carried out through the Multilevel Structural Equation Model (MSEM).
Results: The findings related to the first model did not provide evidence for either direct or indirect effects of the inquiry-based self-efficacy on inquiry skills, achievement goal orientation, and learning strategies. However, findings from the final models provided evidence for both direct and indirect effects of separately inquiry-based self-efficacy and the achievement goal orientation on the inquiry skills through the learning strategies.
Conclusions: This study demonstrates the potential that relations with self-efficacy, achievement goal orientation, and task value theory while improving inquiry skills. 相似文献
Purpose The study examined how an interactive theatre performance, where professional actors deliver a performance but invite regular audience participation as a way to promote active learning, benefited both understanding of plant reproduction and attitudes towards plants. Perceptions of the play and the way in which specific elements influenced learning and emotions were examined in detail and placed in a theoretical context.
Sample Opportunity sampling was used to recruit participants from five public primary schools in Devon, UK. One hundred and forty-four students (aged 9–11 years) participated in the study.
Design and methods A mixed methods approach was adopted. Quantitative analysis of pre- and post-intervention knowledge tests involved t-tests and repeated measures ANCOVA. Qualitative analysis of semi-structured interviews made use of an emerging theme analysis with a priori categories.
Results Pre- and post-intervention tests indicated an increase in both knowledge of plant reproduction and positive attitudes towards plants. Follow-up interviews identified elements that were particularly beneficial for learning and enjoyment, including the thematic singing, humour, novelty of the play, visual elements and participatory art activities.
Conclusions This case study demonstrates the potential that an interactive theatre production offers for enhancing appreciation and interest in school science while improving knowledge. 相似文献
Purpose: This study frames peer assessment as a social process in the science classroom. The aim is to explore peer assessment in science education as social practice in order to contribute to an understanding of the affordances and constraints of using peer assessment as a learning tool in science education.
Design and Method: The study was conducted in four lower secondary school classes, school years 8 and 9, in two different schools. An intervention study was designed focussing on the topic of experimental design. It involved the students in a process of peer assessment where they designed experiments individually, and then exchanged their designs, conducted each other’s experiments, provided feedback to each other and revised their original design after discussing the feedback in groups. Data were collected in the form of audio recordings of student discussions and written work.
Results: The results show that, although not all peer feedback resulted in revisions, peer feedback was useful to the students in group interaction when negotiating quality in their work.
Conclusions: To conclude, the potential for using peer assessment in science education should not only be evaluated through the students’ revisions but also in terms of in what ways the feedback constitutes interactional resources for defining quality in student work. 相似文献
Design/methodology/approach: FFSs that are commonly used in guiding rural development processes involve a long process of preparation, weekly meetings and dissemination of new technologies with a greater knowledge flows from researchers or institutions to farmers than contrariwise. We have simplified FFS components and modified its curriculum focusing on extracting and integrating farmers’ feedback into adaptation measures. Surveys were conducted and their results were validated through focus group discussions, which provided an adequate database to simplify the steps in the FFS approach.
Findings: Only four meetings for agroecosystems analysis that emphasised an analytical and reflective learning cycle generated suitable adaptation measures selected from farmers’ feedback. Repetition of the shortened FFS over several rice cropping cycles proved more effective than the frequent meetings within one cropping cycle.
Practical implications: The modified FFS could be considered as a promising approach to training farmers, whilst simultaneously identifying and discovering adaptations of agricultural innovations and monitoring the evolution of complex polycultures like CRSs, under diverse conditions.
Theoretical implications: The modified FFS provides participants additional time to reflect on the training topics, resulting in a significant improvement in their knowledge and the performance of the CRS.
Originality/value: The modified FFS approach is focused on reflexive learning cycles and adaptation of innovations. Therefore, it is highly suitable for management of complex polycultures such as CRSs. 相似文献
Purpose: The purpose of this study was to examine the impact on overall educational performance as a result of engaging with technology subjects at post-primary level.
Sample: A five year cohort study was designed to gather longitudinal data from a total sample of 1761 pupils’ grades from the Irish Leaving Certificate examination. The sample was distributed across four schools.
Design and methods: Grades from the Irish Leaving Certificate were selected because the examination is considered high stakes as it serves as the country’s primary mechanism for matriculation into third-level education. Individual examinations are designed externally to schools by a government body ensuring the validity of each examination in capturing the holistic interpretation subject syllabi. Finally, a points system is used to score each examination facilitating comparisons between subjects.
Results: The results show that pupils who study the technology subjects are statistically significantly less likely to perform well overall in comparison to pupils who study science and mathematics subjects. They also show that for pupils who study the technology subjects, those subjects are statistically significantly likely to be their best performing subjects.
Conclusions: Due to the array of variables impacting subject selection, a definitive causal explanation cannot be deduced from the data for these results. However, it is possible to infer that the variance in knowledge types between the science and technology subjects has an impact on the results. A case is made that a compulsory technological component should be incorporated into educational curricula to provide a comprehensive and general education and to facilitate the holistic development of pupils. 相似文献
Design/methodology/approach: The paper presents a model of four reflective practice modules conceived as successive building blocks in the professional development of a reflective agricultural advisor and examines the model through the lens of theory and the lens of experience of the first cohort of students to complete the programme.
Findings: Experiential learning with structured critical reflection is shown to support the integration of knowledge gained into new professional identities as agricultural advisors.
Practical Implications: Curricula for higher education in agricultural extension need to be revitalised and refreshed to address the mismatch between the emphasis on the social dimensions of extension in the literature and the general lack of attention to this in the education and formation of agricultural advisors.
Theoretical Implications: The paper presents a model of reflective practice that draws on experiences in other professions that could be applied to early career and continuing professional development for agricultural advisors.
Originality/Value: By presenting a model for reflective practice, the author intends to stimulate a wider discussion on the importance of the different levels of reflection in agricultural extension higher education. 相似文献
Purpose: This study explores STEM students’ encounters with an interdisciplinary first year. Specifically, motivational patterns towards learning in two introductory courses followed by students from multiple study programmes are investigated.
Sample: 173 Danish undergraduate students enrolled in three science programmes: biomedicine; biochemistry and molecular biology; and physics.
Design and methods: Within the framework of Self-Determination Theory, a measure of autonomous and controlled motivation forms the basis for quantitative analyses (n = 173). A qualitative thematic analysis of students’ open responses further supplements and gives nuance to the findings.
Results: The motivational pattern of physics students is found to differ significantly from that of biochemistry and molecular biology (BMB) students and biomedicine students. The comments reveal that some students struggle to realise the relevance of the course content for their chosen study programme to an extent that makes them reconsider their study choice.
Conclusions: The study offers input to the discussion of how to present inter- and/or multidisciplinarity to students and points to implications on two levels: curriculum design and course content. The findings are of importance to educational planners, decision-makers and teachers dealing with the motivational range that exists within their courses. 相似文献
Design and methodology: We used participatory action research (PAR) in a programme building sustainable farming practices for nutrition and income in Solomon Islands as our case study. Two qualitative PAR data streams were analysed: (i) documentation of community activities over three years including action planning, learning activities, training workshops, focus group discussions, key informant and informal interviews and (ii) documentation of the research teams’ own learning and reflection sessions.
Findings: Agricultural research and learning activities facilitated through PAR can help researchers and extension officers see, understand and challenge processes that cause social exclusion and marginalisation and lead to inequitable access to agricultural opportunities. A combination of (i) starting with a collective vision; (ii) facilitating systematic reflection exercises; and (iii) having locally tuned facilitators creating safe spaces; makes processes of social exclusion tangible, discussable and ultimately actionable, illustrating the potential of the research and extension processes to facilitate social change in real time.
Theoretical Implications: The paper makes a contribution to the growing body of theory and literature on innovation systems and people-centred approaches to agricultural development, by highlighting the facilitation challenges and opportunities that can create more learning focused and power-aware agricultural programming.
Practical Implications: Our approach, examined in this paper, can improve implementation of policies such as the Solomon Islands Agriculture and Livestock Sector Policy (2015–2019), which aims for active participation of women and youth in agricultural development.
Originality: Using a PAR approach to discover how agricultural research and extension activities can help transform the processes that cause social exclusion and create disadvantage and marginalisation. 相似文献
Design/methodology/approach: We applied principles of Transformative Learning and Communicative Action theories to design a learning process structured by the Qualitative Expert Assessment Tool for Conservation Agriculture Adoption in Africa (QAToCA). Elements of the process include: agroecosystem health exploration, stakeholder mapping, innovation timeline, participatory video, the QAToCA exercise, and specifying change promotion. We tested this approach with a group of farmers and experts in Koumbia, Burkina Faso.
Findings: The agroecosystem in Koumbia is under demographic, economic, and climatic pressure. Conservation Agriculture has not been successfully integrated into socio-economic realities or implemented beyond a trial scale. The stakeholder mapping showed that dominant economic players and traditional means of communicating are essential to achieve innovation. Past interventions were not coordinated and focused on technical challenges. The participatory videos were rich in contextual information and created process ownership for research participants. The QAToCA provided a structure for lessons learned and suggestions for change.
Practical implications: The learning process may be applied to initiate innovation initiatives in an efficient manner.
Theoretical implications: The study shows how Transformative Learning and Communicative Action theories can be used for agricultural innovation. It also underlines the need for further work on how to address the implicit superiority of the process initiator and the integration of learning in institutional practice.
Originality: Few studies have attempted to design and test learning processes on agricultural innovation based on theories of learning and Communicative Action. 相似文献
Purpose: The purpose of this study was to identify preservice teachers’ ideas about how to increase students’ long-term interest in science.
Sample: The participants were 235 preservice primary teachers and 33 preservice secondary science teachers.
Design and Methods: Data collection was by questionnaire, interview and classroom observations.
Results: It was found that participants in both primary and secondary groups had very similar ideas about how to develop pupils’ long-term interest in science. These ideas mainly involved the use of hands-on activities, making science relevant, and using student-centred strategies or electronic media to make lessons fun and to enhance engagement. These can be interpreted as representing sources of situational interest (i.e. short-term interest arousal). These ideas broadly parallel the current theory on interest development, such that long-term individual interest is thought to develop from repeated experiences of short-term, situational interest.
Conclusion: The participants’ ideas in this study were intuitive, because they were not derived from an understanding of theory, but rather from their personal experiences of interest arousal at university, school and practicum. Nevertheless, their ideas were workable for a practitioner, because they broadly paralleled current theory on interest development. 相似文献
Objective: We explored the relationship between students’ first programming languages and both their final grades in an introductory computer science course and their attitudes about programming.
Method: Multiple matching techniques compared those whose first language was graphical (e.g., Scratch), textual (e.g., Java), or absent prior to college.
Findings: Having any prior programming experience had positive effects on both attitudes about programming and grades in introductory computer science courses. Importantly, students whose first language was graphical had higher grades than did students whose first language was textual, when the languages were introduced in or before early adolescent years.
Implications: Learning any computer language is better than learning none. If programming is to be taught to students before early adolescence, it is advised to start with a graphical language. Future work should investigate the transition between different types of programming languages. 相似文献
Purpose: The purpose of this exploratory study is to investigate student perceptions in a Science Extended Curriculum Program (ECP) of both the traditional pen and paper method they used in 2016, and the new online resource method they used in 2017 to better prepare them for Physics laboratories, and to compare the two methods.
Sample: N = 51 students from a first-year Extended Curriculum Programme in physics at a South African university voluntarily participated in this study.
Design and methods: The research was conducted using two non-standardised structured questionnaires where the enrolled ECP students were asked both open-ended – and closed questions (using a Likert response scale). Google Forms using graphs assessed these responses. An additional source of data was iKamva/Sakai which is the University of Western Cape’s institutional Learning Management (LMS) system, which allowed for detailed information regarding online activities.
Results: Four main research questions focussing on preparedness, time spent, lab activities and online resources were identified. Findings from these suggest that an introduction of an online environment positively affected the students’ perceptions of the online environment for pre-laboratory preparation in comparison with using traditional pen and paper.
Conclusions: The present study has successfully managed to both reveal that the introduction of online environment for Physics laboratories brought about some positive benefits as perceived by the students, as well as fruitful avenues for future research. While more work is needed, in terms of research and continuing evaluation of eLearning in Physics education, there is reason to be positive in terms of renewed emphasis to add blended learning within the broader Physics learning and teaching communities. 相似文献
Design/Methodology/Approach: Guided by the Unified Theory of Acceptance and Use of Technology (UTAUT), this study followed a correlational design and survey data were conveniently collected from 200 farmers of Trinidad.
Findings: Findings showed most farmers of the sample knew how to send and receive text messages, and many owned Internet-enabled smartphones. In addition, most farmers were willing to communicate with extension officers through text messages.
Practical Implications: Ministry Extension should revisit and revise their policies of communicating with farmers. Administrators should encourage extension officers to use SMS to respond to farmers’ requests and information needs.
Theoretical Implications: While the UTAUT provided an appropriate framework for understanding farmers’ use of text messaging, researchers should tailor the moderator variables to the country’s context.
Originality/Value: This study is the first to look at farmers’ willingness to use two-way information communication technologies in Trinidad. Results showed there is potential for Ministry Extension to use text messaging to communicate with farmers. 相似文献
