The current impetus for increasing STEM in K-12 education calls for an examination of how preservice teachers are being prepared to teach STEM. This paper reports on a study that examined elementary preservice teachers’ (n = 21) self-efficacy, understanding of science concepts, and computational thinking as they engaged with robotics in a science methods course. Data collection methods included pretests and posttests on science content, prequestionnaires and postquestionnaires for interest and self-efficacy, and four programming assignments. Statistical results showed that preservice teachers’ interest and self-efficacy with robotics increased. There was a statistically significant difference between preknowledge and postknowledge scores, and preservice teachers did show gains in learning how to write algorithms and debug programs over repeated programming tasks. The findings suggest that the robotics activity was an effective instructional strategy to enhance interest in robotics, increase self-efficacy to teach with robotics, develop understandings of science concepts, and promote the development of computational thinking skills. Study findings contribute quantitative evidence to the STEM literature on how robotics develops preservice teachers’ self-efficacy, science knowledge, and computational thinking skills in higher education science classroom contexts.  相似文献

To determine the impact of an assignment and workshop intended to increase students’ information literacy skills, we conducted a quasi-experiment using a pretest-posttest assessment with undergraduate students in four sections of an introduction to developmental psychology course. Two sections (N = 81) received the assignment and instructions only, acting as the control group; two sections (N = 76) received the librarian-led workshop in addition to the assignment and instructions. Results of an independent-samples t-test revealed a significant difference on posttest scores on students’ information literacy skills between those who participated in the workshop and those who did not. There was also a positive change in students’ subjective views of their ability to use the library and online library resources.  相似文献

Abstract

The aim of this article is to report on a study conducted to assess the effect of an intervention programme to improve SRL and the achievement of a group of poorly performing undergraduate students at the Tshwane University of Technology. SRL was used as theoretical framework. The case study reports on 20 Engineering students who attended learning skills intervention sessions and wrote a college version of the learning and study strategies inventory (LASSI) pre-test and post-test. The intervention consisted of 12 workshop sessions presented over a period of three months. The LASSI pre-test showed that the group scored below the 50th percentile on four scales (anxiety, attitude, selecting main ideas and test-taking strategies). Observed improvements in the post-test scores of the LASSI scales for seven out of ten scales were statistically significant. The students’ academic achievements also improved. The findings are important for improving student success and throughput in South African higher education.  相似文献

The aim of this study was to explore a group of prospective primary teachers’ conceptual understanding of diffusion and osmosis as they implemented a 5E constructivist model and related materials in a science methods course. Fifty prospective primary teachers’ ideas were elicited using a pre- and post-test and delayed post-test survey consisting of ten two-tier questions of which an explanatory part was integral. Individual interviews were conducted with six prospective teachers at the end of the implementation of the unit using four questions. Test scores were analyzed quantitatively and qualitatively. Post-instructional interviews were analyzed qualitatively. Statistical analysis using one-way ANOVA of student test scores pointed to statistically significant differences between pre- and post- and delayed post-test (p < 0.05). A qualitative analysis of the prospective teachers’ explanations in the two-tier questions revealed changes in their ideas overtime. Both quantitative and qualitative analyses suggest that the teaching activities promoted students’ conceptual understanding. No statistically significant differences were found between post-test and delayed post-test scores, suggesting that the teaching activities based on 5E model enabled students to retain their new conceptual understanding.  相似文献

In this paper we investigate whether computer programming has an impact on high school student’s reasoning skills, problem solving and self-efficacy in Mathematics. The quasi-experimental design was adopted to implement the study. The sample of the research comprised 66 high school students separated into two groups, the experimental and the control group according to their educational orientation. The research findings indicate that there is a significant difference in the reasoning skills of students that participated in the “programming course” compared to students that did not. Moreover, the self-efficacy indicator of students that participated in the experimental group showed a significant difference from students in the control group. The results however, failed to support the hypothesis that computer programming significantly enhances student’s problem solving skills.  相似文献

A study was carried out to test the effects of a 2-week structured intervention program on academically challenged students’ career development. A quasi-experimental study was designed using pre-tests, post-tests, and a control group approach to examine the effects of the intervention program. Data were collected from both the experimental and control groups. The test was carried out on eight schools in the state of Kedah in Malaysia. Eight school counselors were trained to facilitate the assignment to the experimental groups and to collect data. A total number of 335 students with low academic achievement participated in this study. This number included male (43.6 %) and female (56.4 %) students who were aged 15–16 and a half. Modes of measurement used consisted of a career planning inventory (measuring career planning skills), an academic learning motivation scale (measuring attitude toward academic learning), and an academic study skills test (measuring academic study competencies). Analysis was performed using t-tests and the multivariate analysis of variance to examine the differences in the mean scores. The results show that the sample’s career academic score improved significantly from the pre-test to the post-test. A simple regression analysis was also performed to see the effect of the intervention program on the three dependent variables, which revealed that the career intervention program has positive and significant effects on the three variables. However, further studies on the career program for academically challenged students are highly recommended to support the present study.  相似文献

ABSTRACT

Numerous studies show the positive effects of introducing video games into learning contexts. These instruments help develop twenty-first-century skills, such as creativity, from a dual perspective: (i) the students’ perspective, since they develop skills and competencies that allow them to find innovative solutions to the challenges posed by games, and to become digital culture producers; and (ii) the education professionals’ perspective, to use these instruments in schools and thereby change the way students learn. Using a sample of 85 first-year secondary school students, this study aims to provide empirical evidence about the development of creativity through the introduction of video games in the classroom. To do this, an eight-week pedagogical workshop was developed in which the Minecraft video game was introduced in the subject of technology. To assess the results of the workshop, the participants’ creativity was analysed using a pre-test/post-test design through the CREA Creative Intelligence Test, as well as the evaluation of the students’ machinima productions by their teachers. Results show a significant increase in creativity and high scores for machinima productions, highlighting the opportunity to introduce these tools in classrooms in order to develop innovative educational contexts where creative processes and products are the protagonists.  相似文献

This study evaluated the effects of HeadsUp! Reading (HUR), a professional development literacy workshop series, with and without supplementary mentoring on early childhood educators’ (ECEs) practices and its subsequent effect on preschool children's literacy skills. ECEs who served children in high poverty communities participated in a 15-week satellite broadcast training series. Pre- and post-assessments were completed for both the control and intervention groups. Participants in HUR and HUR + mentoring significantly exceeded the control ECEs on the quality of their classroom environments. Children's literacy skills improved more in the HUR classrooms than in control classrooms. Mentoring did not enhance preschool children's literacy skills more than HUR alone. The treatment was equally effective for Spanish- and English-speaking children. Early childhood educator participation in HeadsUp! Reading can enhance the effectiveness of classroom literacy practices and has subsequent benefits on language and literacy skills of preschool children from poverty backgrounds. These findings further support the crucial role of high quality programs for the development of children's literacy skills.  相似文献

Several researchers have shown that invented spelling activities in kindergarten foster preschool children’s early literacy skills. However, few studies have assessed its impact on learning to read and write in the first year of primary school. Our goal was to analyse the impact of an invented spelling programme with kindergarteners on their literacy skills until the end of Grade 1. A follow-up study was conducted with 45 five-year-old Portuguese children attending two classes of two schools in Lisbon. The teaching effect was controlled as children from each class were randomly assigned into two groups (experimental/control) — equivalent on letter knowledge, cognitive abilities and phonological awareness. The participants were assessed in kindergarten with a pre-test, immediate post-test and delayed post-test (spelling; reading; phonemic awareness) and at the end of Grade 1 (spelling; reading). The experimental group participated in invented spelling sessions, while control children participated in storytelling activities. Data analysis revealed statistically significant differences between the two groups. The experimental group scored higher, not only in kindergarten but also in the follow-up year for all literacy measures.  相似文献

Reading skills are an important component of academic success for school-age youth, and are associated with increased academic performance and positive attitudes about school. The presence of an animal appears to reduce stress during reading. Therefore, the goal of this study was to assess the feasibility and effects of a 6-week after-school canine-assisted reading program in a public elementary school setting. Second-grade students were randomized to either an intervention group (n?=?14) in which they read to a registered therapy dog for 30 min once weekly for 6 weeks or a control group (n?=?14) with a standard classroom curriculum. Children’s reading skills were assessed biweekly and attitudes about reading were assessed pre- and post-intervention. The 6-week after-school canine-assisted reading program was feasible. Reading skill scores did not change significantly for either group. Although scores on recreational reading attitudes also did not change significantly for either group, the academic reading attitudes scores increased significantly in the intervention group (p?=?.002), but not in the control group (p?=?.06). These results support the benefits of an animal-assisted intervention for child literacy on children’s attitudes about reading and can inform future programs evaluating reading programs that include dogs.  相似文献

The aim of the present study was to investigate the effect of the “Visual Awareness Education Programme” developed to support the visual literacy skills of preschool children. The study group comprised 40 children (20 children in the experimental group and 20 children in the control group) attending preschool in the 2014–2015 school year. The pre-test post-test experimental model was used in the study. The “Visual Literacy Inventory for Preschool Children” and the “Children’s Visual Literacy Rating Inventory for Parents” were used to determine visual literacy level of children. Study results revealed significant differences in favour of the experimental group children in the sub-dimensions and the post-test scores of the “Visual Literacy Inventory for Preschool Children” and the post-test scores of the “Children’s Visual Literacy Rating Inventory for Parents”.  相似文献

The aim of the present study was to investigate the effect of productive classroom talk and metacommunication on the development of young children’s oral communicative competence and subject matter knowledge. This study can be characterized as a quasi-experimental study with a pre-test-intervention-post-test design. A total of 21 teachers and 469 children participated in this study. 12 teachers were assigned to the intervention condition and participated in a Professional Development Program on productive classroom dialogue. Multilevel analyses of children’s oral communicative competence pre- and post-test scores indicated that our intervention had a significant and moderate to large effect on the development of young children’s oral communicative competence. No significant effects were found for children’s subject matter knowledge. The results of this study suggest that dialogically organized classroom talk is more beneficial than non-dialogical classroom talk for the development of children’s oral language skills.  相似文献

The main purpose of this study was to investigate the effects of cooperative learning based on conceptual change approach instruction on ninth-grade students’ understanding in chemical bonding concepts compared to traditional instruction. Seventy-two ninth-grade students from two intact chemistry classes taught by the same teacher in a public high school participated in the study. The classes were randomly assigned as the experimental and control group. The control group (N?=?35) was taught by traditional instruction while the experimental group (N?=?37) was taught cooperative learning based on conceptual change approach instruction. Chemical Bonding Concept Test (CBCT) was used as pre- and post-test to define students’ understanding of chemical bonding concepts. After treatment, students’ interviews were conducted to observe more information about their responses. Moreover, students from experimental groups were interviewed to obtain information about students’ perceptions on cooperative work experiences. The results from ANCOVA showed that cooperative learning based on conceptual change approach instruction led to better acquisition of scientific conceptions related to chemical bonding concepts than traditional instruction. Interview results demonstrated that the students in the experimental group had better understanding and fewer misconceptions in chemical bonding concepts than those in the control group. Moreover, interviews about treatment indicated that this treatment helped students’ learning and increased their learning motivation and their social skills.  相似文献

Abstract

This mixed methods study examined how engagement in robotics and game design influenced students’ self-efficacy, STEM attitudes, and computational thinking (CT) skills. Predominantly African-American students engaged in engineering and computer science tasks during informal learning environments. Results revealed students’ self-efficacy scores on computer gaming increased significantly. Focus group data supported these findings, revealing that computer programing was challenging, but students enjoyed the tasks, added elements of culture in some cases, and valued the agency the tasks provided. Focal students were also able to make connections to STEM-related careers. Observational data demonstrated that focal students exhibited substantive CT during robotics and moderate CT during game design. Results support the idea that robotics and game design may be used to broaden underrepresented students’ participation in STEM.  相似文献

Twenty-first century education systems should create an environment wherein students encounter critical learning components (such as problem-solving, teamwork, and communication skills) and embrace lifelong learning. A review of literature demonstrates that new technologies, in general, and robotics, in particular, are well suited for this aim. This study aims to contribute to the literature by studying teachers' perceptions of the effects of using robotics on students' lifelong learning skills. This study also seeks to better understand teachers' perceptions of the barriers of using robotics and the support they need. Eleven primary/elementary teachers from Newfoundland and Labrador English Schools District participated in this study. The results of this study revealed that robotics is perceived by teachers to have positive effects on students' lifelong learning skills. Furthermore, the participants indicated a number of barriers to integrate robotics into their teaching activities and expressed the support they need.  相似文献

A pre- and post-test quasi-experimental design was used to test the impact of a 30-week, theoretically-based social and emotional learning (SEL) curriculum, The RULER Feeling Words Curriculum (“RULER”), on the academic performance and social and emotional competence of 5th and 6th grade students (N = 273) in fifteen classrooms in three schools. Academic performance was assessed by report card grades. Social and emotional competence was assessed with teacher reports of student behavior. Students in classrooms integrating RULER had higher year-end grades and higher teacher ratings of social and emotional competence (e.g., leadership, social skills, and study skills) compared to students in the comparison group. This study provides preliminary empirical evidence that SEL programs like RULER improve important student outcomes.  相似文献

This study examined the effects of a 10 week invented writing program with five-year-old preschoolers (mean age 5.7 years) on their immediate post intervention literacy skills and also the facilitative effects of the intervention on the subsequent learning to read during the first 6 months of schooling. The study included 105 children (54 girls) from 12 preschools in Norway. The preschools were randomly assigned to the experimental group with the invented writing program, or the control group with the ordinary program offered to preschoolers. The classroom-based programs (40 sessions) were conducted by the children’s regular teachers. The children’s emergent literacy skills were evaluated using a pre-test, a post-test and a follow-up test 6 months later, and the data were analyzed using latent autoregressive models. The results showed that the invented writing group performed significantly better than the control group on the post-test for the measures of phoneme awareness (d = .54), spelling (d = .65) and word reading (d = .36). Additionally, indirect effects were observed on the delayed follow-up tests on phoneme awareness (d = .45), spelling (d = .48) and word reading (d = .26). In conclusion, we argue that invented writing appeared to smooth the progress of emergent literacy skills in preschool, including the subsequent reading development in school. Contextualized in a semi-consistent orthography and a preschool tradition that does not encourage the learning of written language skills, the findings add to our knowledge of how children learn to write and read.  相似文献

ABSTRACT

Background and Context: Current introductory instruction fails to identify, structure, and sequence the many skills involved in programming.

Objective: We proposed a theory which identifies four distinct skills that novices learn incrementally. These skills are tracing, writing syntax, comprehending templates (reusable abstractions of programming knowledge), and writing code with templates. We theorized that explicit instruction of these skills decreases cognitive demand.

Method: We conducted an exploratory mixed-methods study and compared students’ exercise completion rates, error rates, ability to explain code, and engagement when learning to program. We compared material that reflects this theory to more traditional material that does not distinguish between skills.

Findings: Teaching skills incrementally resulted in improved completion rate on practice exercises, and decreased error rate and improved understanding of the post-test.

Implications: By structuring programming skills such that they can be taught explicitly and incrementally, we can inform instructional design and improve future research on understanding how novice programmers develop understanding.  相似文献

OBJECTIVE: The effects of the sexual child abuse prevention program ESPACE were evaluated by means of a Solomon-type design with first and third grade children. ESPACE is an adaptation of the American Child Assault Prevention Program (CAP). Possible side effects of the program were also examined. METHOD: A total of 133 children (64 first-graders and 69 third-graders) participated in the study. Children completed a knowledge questionnaire and a video vignette measure designed to evaluate preventive skills towards abusive and potentially abusive situations. A follow-up measure (2 months) was administered to verify whether knowledge and skills were maintained. RESULTS: Results indicated that children participating in the prevention program showed greater preventive knowledge and skills relative to children not participating. Follow-up data showed that knowledge gains were maintained while the preventive skill gains may attenuate. However, while global skill scores decreased between post-test and follow-up, children still showed greater preventive skills at follow-up than before the program. In terms of unanticipated side effects, results revealed that almost half of the parents noted positive reactions following children's participation in the ESPACE program. Furthermore, the majority of parents did not identify negative reactions in their children following their participation in the workshop. CONCLUSION: The findings suggest that the Quebec adaptation of the CAP program was effective in training children in abuse prevention concepts and skills.  相似文献
