ABSTRACT

Background and Context: Computer Science attrition rates (in the western world) are very concerning, with a large number of students failing to progress each year. It is well acknowledged that a significant factor of this attrition, is the students’ difficulty to master the introductory programming module, often referred to as CS1.

Objective: The objective of this article is to describe the evolution of a prediction model named PreSS (Predict Student Success) over a 13-year period (2005–2018).

Method: This article ties together, the PreSS prediction model; pilot studies; a longitudinal, multi-institutional re-validation and replication study; improvements to the model since its inception; and interventions to reduce attrition rates.

Findings: The outcome of this body of work is an end-to-end real-time web-based tool (PreSS#), which can predict student success early in an introductory programming module (CS1), with an accuracy of 71%. This tool is enhanced with interventions that were developed in conjunction with PreSS#, which improved student performance in CS1.

Implications: This work contributes significantly to the computer science education (CSEd) community and the ITiCSE 2015 working group’s call (in particular the second grand challenge), by re-validating and developing further the original PreSS model, 13 years after it was developed, on a modern, disparate, multi-institutional data set.  相似文献

Abstract

Background: This article critically discusses the key tensions and challenges arising from the educational policy borrowing in China, through its current education reform. Focussing on the new curriculum reform (NCR), the paper highlights the interactions and conflicts between foreign and local ideologies and practices.

Sources of evidence: The main sources of evidence that form the basis of the analysis for this article were research data from an open-ended questionnaire and semi-structured interviews conducted with 166 school principals, vice-principals and teachers from China between 2013 and 2015.

Main argument: It is argued that the NCR has borrowed selective ideas and practices from elsewhere, such as a school-based curriculum, student-centred pedagogy and formative assessment. It is further suggested that the borrowed policies are mediated and moderated by the ideological attitude of the Chinese educational stakeholders, stemming from the notion of ‘theory-ladenness’ within an exam-oriented paradigm.

Conclusions: The example of China illustrates the effects of an ideological attitude on educational policy borrowing that challenges the notion of universally appropriate ways of teaching, learning and reforming an educational system.  相似文献

Background and purpose:

The purpose of this study was to investigate the comparative effects of a prediction/discussion-based learning cycle (HPD-LC), conceptual change text (CCT) and traditional instruction on 10th grade students’ understanding of genetics concepts.

Sample:

Participants were 112 10th basic grade male students in three classes of the same school located in an urban area. The three classes taught by the same biology teacher were randomly assigned as a prediction/discussion-based learning cycle class (n?=?39), conceptual change text class (n?=?37) and traditional class (n?=?36).

Design and method:

A quasi-experimental research design of pre-test–post-test non-equivalent control group was adopted. Participants completed the Genetics Concept Test as pre-test–post-test, to examine the effects of instructional strategies on their genetics understanding. Pre-test scores and Test of Logical Thinking scores were used as covariates.

Results:

The analysis of covariance showed a statistically significant difference between the experimental and control groups in the favor of experimental groups after treatment. However, no statistically significant difference between the experimental groups (HPD-LC versus CCT instruction) was found.

Conclusions:

Overall, the findings of this study support the use of the prediction/discussion-based learning cycle and conceptual change text in both research and teaching. The findings may be useful for improving classroom practices in teaching science concepts and for the development of suitable materials promoting students’ understanding of science.  相似文献

BackgroundA number of risk factors for gang involvement have been identified in the literature, such as victimization, poor parental monitoring, aggressive behavior, and affiliation with delinquent peers. However, few studies have examined the influence of maltreatment experiences during childhood on gang involvement later in adolescence.ObjectiveThis study examines how differential experiences of maltreatment might impact future gang involvement.Participants and settingWe analyze self-report data and official maltreatment records on 611 youth (52% female; 76% non-white) in the US, from a larger dataset (Longitudinal Studies on Childhood Abuse and Neglect; N = 1354).MethodsMultinomial logistic regression models were used to examine the influence of experiencing different types of maltreatment on gang involvement.ResultsResults show that childhood experiences of maltreatment (p = .005) generally and neglect (p = .013) specifically were significantly associated with an increased risk of involvement in stable gang affiliations later in adolescence.ConclusionsThese findings demonstrate the value of considering gang involvement as an outcome of maltreatment and tailoring best practice interventions to support maltreated youth at risk of gang involvement.  相似文献

ABSTRACT

Background: Recent developments in STEM and computer science education put a strong emphasis on twenty-first-century skills, such as solving authentic problems. These skills typically transcend single disciplines. Thus, problem-solving must be seen as a multidisciplinary challenge, and the corresponding practices and processes need to be described using an integrated framework.

Purpose: We present a fine-grained, integrated, and interdisciplinary framework of problem-solving for education in STEM and computer science by cumulatively including ways of problem-solving from all of these domains. Thus, the framework serves as a tool box with a variety of options that are described by steps and processes for students to choose from. The framework can be used to develop competences in problem-solving.

Sources of evidence: The framework was developed on the basis of a literature review. We included all prominent ways of domain-specific problem-solving in STEM and computer science, consisting mainly of empirically orientated approaches, such as inquiry in science, and solely theory-orientated approaches, such as proofs in mathematics.

Main argument: Since there is an increasing demand for integrated STEM and computer science education when working on natural phenomena and authentic problems, a problem-solving framework exclusively covering the natural sciences or other single domains falls short.

Conclusions: Our framework can support both practice and research by providing a common background that relates the ways, steps, processes, and activities of problem-solving in the different domains to one single common reference. In doing so, it can support teachers in explaining the multiple ways in which science problems can be solved and in constructing problems that reflect these numerous ways. STEM and computer science educational research can use the framework to develop competences of problem-solving at a fine-grained level, to construct corresponding assessment tools, and to investigate under what conditions learning progressions can be achieved.  相似文献

Pathologizing the Poor: A Framework for Understanding Ruby Payne's Work

The poor person does not exist as an inescapable fact of destiny. His or her existence is not politically neutral, and it is not ethically innocent. The poor are a by-product of the system in which we live and for which we are responsible.

Background: Knowledge construction and technology have been identified as critical for an understanding of the future of teacher education. Knowledge is discovered, applied and created collaboratively from authentic starting points. Today’s new mobile and blended learning environments create increased opportunities for such processes, including learner-centred approaches, authenticity and dialogical knowledge construction. However, teaching still requires appropriate learning design and structuring. The presented study explored, and was designed and implemented, using the ‘Dialogical Authentic Netlearning Activity’ (DIANA) pedagogical model, which is seen as one of the learning designing models for existing digital, open and mobile learning environments.

Purpose: The purpose of this study was to identify the challenges and opportunities inherent in the adoption of the DIANA model and to examine student-teachers’ reflections concerning authentic and dialogical knowledge construction. The focus is on the learning process.

Sample: Participants were 63 student-teachers who were following the study module ‘Networks in Vocational Education’ at the School of Professional Teacher Education, in Hämeenlinna, Finland.

Design and methods: This qualitative study uses a deductive content analysis to discern relationships between the data and the existing theory. The data for this study were drawn from an online questionnaire and participants’ self-reflective accounts.

Findings: The results indicate that achieving deep-oriented learning through dialogical actions is the most challenging part of using the DIANA model. Some of the students had difficulty understanding the concept of ‘authenticity’.

Conclusions: The findings of this study suggest enhancing learner-centred scaffolding and guidance, particularly at the outset of the learning process. In addition, methods that develop dialogical skills and competences ought to be integrated into teacher education as extensively as possible, in order to make collaborative work and problem-solving genuinely dialogical and equal.  相似文献

Background

Budgets for teacher education programmes have been substantially reduced as a result of the global economic crisis.

Purpose

The purpose of this study was to compare the teacher education budget cutting processes and procedures for universities in Romania versus one university in the United States.

Sample

The data were collected from six Romanian universities that all have teacher education programmes. These universities represent the range of higher education quality in the country as indicated by their publication rates. Data from these universities were compared with those from the University of Nevada, Reno (UNR). UNR is the flagship university in the Nevada System of Higher Education, and Nevada has been harder hit by the recent global economic crisis than any other state in the United States and cuts to teacher education there have been substantial.

Design and methods

Data about the budget cutting processes and decisions in the teacher education programmes of six Romanian universities were collected through an electronic survey. These data were compared with the processes and decisions made at the UNR.

Results

The budget cutting processes in Romania were less transparent, and involved less input from stakeholders such as faculty and staff. Most decisions were made at a higher level of authority in Romania, and cuts in Romania were more likely to be across the board rather than more strategically targeted as they were in Nevada.

Conclusions

These differences are discussed in terms of the historical legacy of structures and policies in Romania, and the resistance to reform inherent in those structures and policies.  相似文献

Background: Helping upper elementary and lower secondary school students develop an awareness of various aspects of the nature of science (NOS) and nature of technology (NOT) is a widely recognized goal of science teaching. In this study, we focus on the connections between science and technology (S&T).

Purpose: We report on the design, development, enactment and evaluation of a teaching-learning sequence (TLS) that combines hands-on activities in geometrical optics with explicit epistemological discourse for reflection purposes. The design of the TLS draws on perspectives from the inquiry-oriented and design-based teaching and learning frameworks.

Sample: The enactment of the TLS involved a class of 17 sixth-grade students, aged 10–11 years old, of a public elementary school in Cyprus.

Design and methods: We present findings from written responses to both closed and open-ended tasks as well as follow-up semi-structured interviews that probed students’ understanding of the difference between the main goals of S&T.

Results: The results illustrate elementary students’ readiness to engage with epistemic issues and demonstrate the potential of prompting young learners’ ability to develop informed awareness of the NOS and NOT. The results also provided feedback for the revision of the TLS so as to further enhance its effectiveness in achieving the stated learning objectives.

Conclusion: We discuss the implications of our findings for the teaching of the NOS and NOT and for the design and validation of TLSs. It is possible for students of this age group to develop an awareness of issues related to the NOS and NOT. TLSs can be improved through design-based research approaches to serve as productive tools to this end.  相似文献

Background : Advance organizers are instructional materials that help students use previous knowledge to make links with new information. Short animation movies are a possible format and are well suited for physics, as they can portray dynamic phenomena and represent abstract concepts.

Purpose : The study aimed to determine guidelines for the construction of an instructional short animation movie, with the role of an advance organizer. A film was created in order to evaluate the effectiveness of the approach, making part of a physics lesson and concerning the subject ‘moment of a force’.

Sample : The study took place in a Brazilian school in the city of Arapoti, in the south region of the country. Thirty-eight students participated, having an average age of 16 and following the third year of high school.

Design and methods : Criteria drawn from a literature review directed the construction of the movie and the lesson. Data were collected using pre- and post-tests; registers of oral comments were also done during the class. The post-test included open-ended questions, allowing students to write remarks concerning the lesson and the animation.

Conclusions : The article describes steps and guidelines to orient the process of designing an animation movie with the role of advance organizer. Data indicated that the movie facilitated the construction of links between pre-existent knowledge and the new information presented in the lesson. The proposed methodology can be considered a valid framework to derive similar approaches.  相似文献

ABSTRACT

Background: Undergraduate research is evident in many forms across higher education: in journals, at conferences and on research placements. It is widely reported that undergraduate research can encourage the development of discipline-specific and transferable communication skills and, in some cases, a more complex development of higher-order critical appraisal. Recent studies of extracurricular undergraduate research conferences have also found that participants report a development of self-authorship and an appreciation of the conference as liminal and transformative space. With many published studies measuring immediate feedback surrounding conference events, there is also a need to explore participants’ reflections over a longer term period of time.

Purpose: This small-scale project investigated participants’ self-report of whether and in what ways participation in a non-assessed, extracurricular undergraduate research conference had impacted their academic and professional practices, one year after their involvement in the conference.

Method: The qualitative study took place over two academic years with participants from an undergraduate conference which was held annually. The investigation adopted an action research methodology and completed two cycles of research. Data were collected firstly through an online survey with open questions, yielding feedback from 44 respondents. Focus groups were then conducted with nine of these students to explore this data further. A thematic approach was used to analyse the data.

Findings: The two cycles of data collection and analyses resulted in the identification of four central themes: (1) general positive impact on studies or career; (2) the development of presentation skills and personal confidence; (3) the development of research skills and perspectives; (4) an increased engagement with extracurricular opportunities.

Conclusions: Overall, our analysis identified that participants reported a development in communication skills and an enhanced relationship with the concept of ‘research’ and self-authorship. Students’ report that participation directly led to increased engagement with additional extracurricular activities is particularly noteworthy, as it contributes something new to the growing body of literature surrounding undergraduate research. More widely, the study suggests the potential for undergraduate conferences to act as springboards for increased extracurricular engagement.  相似文献

Abstract

In this paper we address practical questions such as: How do symbols appear and evolve in an inquiry-oriented classroom? How can an instructor connect students with traditional notation and vocabulary without undermining their sense of ownership of the material? We tender an example from linear algebra that highlights the roles of the instructor as a broker, and the ways in which students participate in the practice of symbolizing as they reinvent the diagonalization equation A = PDP?1.  相似文献

This paper reports on part of an ongoing research project in England concerning the Nature of Science (NOS). The particular focus is on the initial thinking of the graduate scientists starting a one-year, Postgraduate Certificate of Education (PGCE) course and the way the course approaches adopted influence their views and understanding of NOS and their teaching. The research is set against a wealth of literature indicating that teachers find it difficult to teach curricula that emphasise NOS. Thus a key impetus for research in this area has been to look for ways that beginning teachers might be better prepared to face such challenges.

Sample

The paper draws on data from three cohorts of secondary PGCE students in a university–schools partnership, involving a total of 169 students.

Design and method

The research lies within a design research tradition. It has used mixed methods, involving written tasks, interviews and focus groups, with an iterative approach where the outcomes from one cohort have been used to inform course developments in successive years.

Results

The results from these cohorts suggest that, while the students starting the course have a less restricted view of NOS than indicated by some other studies, in most cases there is a lack of breadth and depth to their understanding. There is some evidence that the use of specific tasks focusing on NOS in university-based sessions may be helping to develop and deepen understanding. However, the impact of current approaches remains fairly limited and attempts to develop teaching practices often face considerable barriers in the school-based practicum.

Conclusions

Graduate science students’ understanding of NOS as they embark on the PGCE is not highly developed. Hence, the emphasis on aspects of NOS in the school curriculum presents a considerable challenge. This study suggests that there is a need to both further develop an explicit focus on NOS in university-based sessions and to develop closer relationships between schools and university faculty in seeking to support developments in classroom practice in this difficult area.  相似文献

ABSTRACT

Background and Context: In spite of the decades spent developing software visualization (SV), doubts still remain regarding their effectiveness. Furthermore, student engagement plays an important role in improving SV effectiveness as it is correlated with many positive academic outcomes. It has been shown that the existing SV has failed to engage students effectively.

Objective: Therefore, there is a need to understand the theories behind SV design from the engagement perspective to produce a roadmap for future tool construction. The aim of this study was to identify the theories have been used in literature to explain or construct student engage- ment with SV in computer science courses for novices.

Method: We performed a systematic literature review that identified a total of 58 articles published between 2011 and 2017, which were then selected for the study. However, among them, only 18 articles had discussed their theoretical framework.

Findings: The results of this study show a richness in the theoretical framework obtained from different disciplines, however, constructivism is still dominant in the computing education research (CER) domain. It is evidently clear from the findings that the theories generated from the CER domain are needed to enhance the effectiveness of SV.

Implications: As a result of this review, we suggest several design principles and engagement attributes to be considered while creating an engaging SV.  相似文献

Background: Scientific models have important roles in science and science education. For scientists, they provide a means for generating new knowledge or function as an accessible summary of scientific studies. In science education, on the other hand, they are accessible representations of abstract concepts, and are also organizational frameworks to teach and learn inaccessible facts. As being indispensable parts of learning and doing science, use of scientific models in science classes should be reinforced. At this point, uncovering pre-service science teachers’ (PSTs) understandings of scientific models are of great importance since they will design and conduct teaching situations for their students. Purpose: The study aimed to provide an answer to the research question: What understandings do PSTs possess about scientific models? Sample: The sample of the study consisted of 14 PSTs enrolled in an Elementary Science Education program in a public university in Ankara, Turkey. Design and methods: Data were collected by using an open-item instrument and semi-structured interviews, and were analyzed by using qualitative data analysis methods. Results: Findings showed that PSTs held fragmented views of models by having informed views in some aspects while having naïve views on others. That is, although they displayed a constructivist orientation by acknowledging the presence of multiple models for the same phenomenon depending on scientists’ perspectives or creativity involved in the production of scientific knowledge, PSTs also expressed logical positivist views by believing that models should be close to the real phenomena that they represent. Findings further revealed that PSTs generally conceptualized models’ materialistic uses, yet they did not think much about their theoretical and conceptual uses. It was observed that roles like reifying and visualizing were overestimated and models were dominantly characterized as three-dimensional representations. Conclusions: It is clear that PSTs, having difficulties in grasping the concept of models, would possibly have problems in planning their lessons effectively and would not develop accurate concepts in their students. These findings apparently support the need for appropriate pedagogic training of PSTs to scientifically reflect on and professionally make use of models in science classes.  相似文献

Background: The active involvement of learners as critical, reflective and capable agents in the learning process is a core aim in contemporary education policy in Australia, and is regarded as a significant factor for academic success. However, within the relevant literature, the issue of positioning students as agents in the learning process has not been fully examined and needs further exploration.

Purpose: This study aims to explore ways in which aspects of self-regulated learning theory may be integrated with the concept of agentic engagement into classroom practice. Specifically, the study seeks to scaffold students’ self-assessment capabilities and self-efficacy by using a formative assessment-as-learning process. The research examines how scaffolded planning, as part of the forethought phase in the Assessment as Learning (AaL) process, influences self-regulation and student agency in the learning process.

Sample: 126 students from school years two, four and six (student age groups 7, 9 and 11 years), and 7 teachers at an independent (co-educational, non-religious) primary school in the Northern Territory, Australia, participated in the study.

Design and methods: Conducted as a one-setting, cross-sectional practitioner research study, the data sources included students’ planning templates, writing samples, interviews with students and teachers and email correspondence with teachers. The data were analysed for emerging themes and interpreted from a framework of social cognitive theory.

Findings: In this study, students were given the opportunity and support to exercise agentic engagement. Findings suggested that, in particular, students who were identified by their teachers as low-achieving and/or with poor motivation, were perceived by the teachers as exceededing expectations by demonstrating relatively greater motivation, persistence, effort and pride in their work than would be the case usually.

Conclusions: The findings from this formative AaL study suggest that AaL has the potential to help scaffold primary students’ development of assessment capabilities.  相似文献

Background: In the last decade, much research attention has been paid to notions of leadership and the professional identity of school. It is widely agreed that school principals play a very important role in school improvement; international reports point to ‘school leadership’ as a key factor in education quality, and recent studies suggest that the leadership identity of principals is critical for achieving effective leadership in schools worldwide.

Purpose: The purpose of this study was to conduct a thematic exploration of the literature relating to school principals and leadership identity.

Design and methods: A scoping review was carried out. Two major databases were searched for papers published on this topic in the last decade. Once we had established an overview of research on this subject, we conducted a thematic analysis to identify the topical focus of research.

Results: We found that the literature reflected an increasing and intensified interest in the topic of school leadership as the decade progressed. Furthermore, a range of emerging subtopics was identified. These included the relationship between school culture and professional identity in school principals; the influence of ethical and personal factors on the professional development of principals; the dilemmas of balancing education policies and personal experiences; and the relationships between gender identity, racial identity, professional experience/career, training and leadership identity.

Conclusions: Several key issues emerged from the studies included in this review, such as the importance of external and internal influences in the construction of the professional identity of school principals. Some of the research suggested that school leaders felt the need to develop a new professional identity. Overall, the study indicates that school leadership and its relationship with school improvement should remain an important focus for educational research investigation.  相似文献
