Strategizing computer-supported collaborative learning toward knowledge building

The purpose of this paper is to explore how university students can develop knowledge in small task-based groups while acquiring hands-on computer skills. Inspired by the sociocultural perspective, this study presents a theoretical framework on co-construction of knowledge and on computer-supported collaborative learning. The participants were selected from student teachers in Rwanda after a training program on searching, retrieving and exploiting web-based literature. The findings show that university students working together in small groups to acquire hands-on computer skills can adopt one of three major learning patterns: individual-led, group-led or individual-group hybrid-led. Moreover, the results indicate that the group-led framework seems to create a supportive environment for knowledge building. Nevertheless, university students showed a need for teacher support to enable them to focus on criterion-referenced reflection to regulate their learning.     

The Transition from School to University in Mathematics: Which Influence Do School-Related Variables Have?

Particularly in mathematics, the transition from school to university often appears to be a substantial hurdle in the individual learning biography. Differences between the characters of school mathematics and scientific university mathematics as well as different demands related to the learning cultures in both institutions are discussed as possible reasons for this phenomenon. If these assumptions hold, the transition from school to university could not be considered as a continuous mathematical learning path because it would require a realignment of students’ learning strategies. In particular, students could no longer rely on the effective use of school-related individual resources like knowledge, interest, or self-concept. Accordingly, students would face strong challenges in mathematical learning processes at the beginning of their mathematics study at university. In this contribution, we examine these assumptions by investigating the role of individual mathematical learning prerequisites of 182 first-semester university students majoring in mathematics. In line with the assumptions, our results indicate only a marginal influence of school-related mathematical resources on the study success of the first semester. In contrast, specific precursory knowledge related to scientific mathematics and students’ abilities to develop adequate learning strategies turn out as main factors for a successful transition phase. Implications for the educational practice will be discussed.     

Content and timing of feedback in a web-based learning environment: effects on learning as a function of prior knowledge

This study investigated the effectiveness of different types of feedback content (elaborate versus global) and feedback timing (immediate versus delayed) for learning genetics in a web-based learning environment as a function of learners' prior knowledge. It was hypothesized that learning outcomes of students with low prior knowledge would be fostered by immediate elaborate feedback, whereas those of students with more prior knowledge would be enhanced by delayed global feedback. Students' perceptions of the feedback they received were explored. Results showed a significant positive effect of global feedback on learning outcomes for higher prior knowledge learners, although those who received elaborate feedback gave a higher appreciation rating. The findings are discussed in terms of implications for the design and delivery of feedback in web-based learning environments.     

Meaningful learning from practice: web-based video in professional preparation programmes in university

Web-based video is one of the technologies which can support meaningful learning from practice – in addition to practical benefits such as accessibility of practices, flexibility in updating information, and incorporating video into multimedia resources. A multiple case study was set up on the use of a web-based video learning environment in two post-graduate teacher education programmes and two university Bachelor programmes. The later analysis of practice was reported by students to be the most valuable aspect. Teacher feedback was perceived as more helpful than peer feedback, characterising most peer feedback as pep-talk. Direct video observation is suggested to be insufficient for students’ reflection on conceptual questions and on a more general level of practical experience. Implications for the preparation for professional practice in the university context are indicated.

Effects of active‐learning experiences on achievement,attitudes, and behaviors in high school biology

Active‐learning labs for two topics in high school biology were developed through the collaboration of high school teachers and university faculty and staff and were administered to 408 high school students in six classrooms. The content of instruction and testing was guided by State of Texas science objectives. Detailed teacher records describing daily classroom activities were used to operationalize two types of instruction: active learning, which used the labs; and traditional, which used the teaching resources ordinarily available to the teacher. Teacher records indicated that they used less independent work and fewer worksheets, and more collaborative and lab‐based activities, with active‐learning labs compared to traditional instruction. In‐class test data show that students gained significantly more content knowledge and knowledge of process skills using the labs compared to traditional instruction. Questionnaire data revealed that students perceived greater learning gains after completing the labs compared to covering the same content through traditional methods. An independent questionnaire administered to a larger sample of teachers who used the lab‐based curriculum indicated that they perceived changing their behaviors as intended by the student‐centered principles of the labs. The major implication of this study is that active‐learning–based laboratory units designed and developed collaboratively by high school teachers and university faculty, and then used by high school teachers in their classrooms, can lead to increased use of student‐centered instructional practices as well as enhanced content knowledge and process learning for students. © 2007 Wiley Periodicals, Inc.

Can learning of basketball be enhanced through a web-based multimedia course? An experimental study

This study’s aim is the creation of a web-based multimedia course for Physical Education (PE) students’ familiarization with the teaching of basketball, and the evaluation of its use as a complementary tool to conventional instruction, in terms of learning effectiveness and student acceptance. The course includes multimedia learning material as well as interactive learning activities and quizzes on the cognitive components of basic basketball skills and on other basketball-related topics (history of the sport, referee’s signals, training aids, basketball court). The study involved 88 undergraduate students during one semester. They were randomly assigned to two groups: a group that used the web-based multimedia course and also attended a conventional face-to-face course on the teaching of basketball (N?=?45), and another group that only attended the conventional face-to-face course (N?=?43). A pretest/posttest research design was followed. For both groups basketball knowledge was measured at the beginning and at the end of the semester through written questionnaires. The responses of the students of the first group towards the web-based course were also assessed, at the end of the semester, through a written feedback questionnaire. Within both groups, significant increases in students’ basketball knowledge were found. However, the web-based multimedia course in combination with conventional face-to-face instruction was significantly more effective than conventional face-to-face instruction alone in increasing students’ cognitive learning regarding the sport of basketball, at the same time being well-accepted by the students. These findings support the effectiveness of blended learning for PE at higher education level as well as the acceptance of this mode of learning by PE students.     

The Content of Physics Self-Explanations

Several earlier studies have found the amount learned while studying worked-out examples is proportional to the number of self-explanations generated while studying examples. A self-explanation is a comment about an example statement that contains domain-relevant information over and above what was stated in the example line itself. This article analyzes the specific content of self-explanations generated by students while studying physics examples. In particular, the content is analyzed into pieces of constituent knowledge that were used in the comments. These were further analyzed in order to trace the source of knowledge from which self-explanations could be generated. The results suggest that there are two general sources for self-explanations. The first is deduction from knowledge acquired earlier while reading the text part of the chapter, usually by simply instantiating a general principle, concept, or procedure with information in the current example statement. The second explanation is generalization and extension of the example statements. Such construction of the content of the example statements yield new general knowledge that helps complete the students' otherwise incomplete understanding of the domain principles and concepts. The relevance of this research for instruction and models of explanation-based learning is discussed.     

Prior knowledge in mathematics and study success in engineering: informational value of learner data collected from a web-based pre-course

The article describes the development and evaluation of a web-based pre-course in mathematics, delivered to four cohorts of engineering students at a German university. Based on demographic, personal, and learning-related data relationships between students’ preconditions, their learning gains in the pre-course, and study success in the degree programme were analysed. The results support the existing literature in that domain-related prior knowledge and secondary school achievement play a dominant role regarding study success in engineering. The analyses also showed that the influence of cognitive predictors could only be compensated for by a strong learner engagement. At-risk students with high pre-course learning gains showed significantly better first-year performance. The number of self-tests a student attempted was positively related to pre-course learning gains and even to first-year performance, suggesting that this variable is a good indicator of student engagement.     

网络多媒体课件中信息流量的控制策略

一个网络多媒体课件所提供的信息流量必须与学生的接受能力相适宜才能取得更好的教学效果。因此,在制作课件时,如何对学生的学习能力进行有效评估,如何根据学生的学习能力在哪些地方进行课件信息流量控制设计,以及在学习过程中学生如何根据自身特点自己掌握控制信息流量,这些问题决定着网络多媒体课件的成败。     

关于远程教育学习支持服务系统构成的思考

远程教育以学生的自主学习为主要特征,但在现实中,有不少学习者限于多年接受灌输式传统学习惯性和自身工作生活处境,对＂求何知、如何学＂的认识不够充分,导致面对浩瀚如烟的网上学习资源,在短期内难以找到适合自己的学习目标和坐标,严重影响了学习质量。因此,需要建立高效、完善的学习支持服务系统,为学生提供个性化学习帮助,使学习者实现有效学习。目前设立学习中心,构建网络学习环境,已经成为远程教育学习过程支持服务的重要工作,这在客观上对学习者支持服务的产生提供了可能性。     

Just-in-Time Teaching Exercises to Engage Students in an Introductory-Level Dinosaur Course

The Just-in-Time Teaching (JiTT) technique allows students to be engaged in course material outside of the classroom by answering web-based questions. The responses are summarized and presented to students in class with a follow-up active learning exercise. College students enrolled in an introductory-level general education geoscience course were surveyed over a two-semester period on their engagement level during lecture and perceived learning of course content. Data show that students are able to reflect on their prior knowledge and construct new knowledge with weekly graded JiTT exercises. Despite increasing and competing pressures outside of the classroom, students reported increased learning and engagement in a course with required weekly assignments.

Student Learning Through Participation in Inquiry Activities: Two Case Studies in Teacher and Computer Engineering Education

The two case studies reported in this article contribute to a better understanding of how inquiry tasks and activities are employed as resourceful means for learning in higher professional education. An observation-based approach was used to explore characteristics of and challenges in students’ participation in collaborative inquiry activities in two first-year introductory courses in teacher and computer engineering education. The findings highlight that the students’ activities varied with regard to focus and structure and were shaped by the types of inquiry tasks, i.e. case analysis and project-based work, by how the inquiry process was guided and supported and the way the domain-specific knowledge resources and practices were introduced. An exploratory strategy and rather confined use of resources characterised the teacher education students’ inquiry, while collaborative programming, a trial-and-error approach and extensive use of external resources that of the engineering education students’. For the teacher students, the main challenge was to construct meaning of conceptual knowledge and to integrate different forms of knowledge as a lens for analysing practice. The computer engineering students experienced challenges with unpacking the underlying principles and knowledge black-boxed in the widely available resources. The article suggests that future research and curriculum designs should depart from a more refined understanding of inquiry as a learning means, by connecting inquiry activities to the specific knowledge domains, the type of tasks most suited to explore each of this domains and the challenges that may arise for students.     

Students’ Perceptions of E‐learning in University Education

This paper examines students’ perceptions of e‐learning taking students at Jönköping University in Sweden as an example. The students had experiences from two years of e‐learning on campus. Students (n = 150) filled in a questionnaire with closed as well as open‐ended questions. The answers were analysed in a multiple regression analysis, putting the students’ perceptions in relation to gender, age, previous knowledge of computers, attitudes to new technology, learning styles and the way of implementing e‐learning at the university. Advantages and disadvantages of e‐leaming were categorized in a qualitative content analysis. The main conclusion from the study was that the strategy of implementing the e‐leaming system at the university was more important in influencing students’ perceptions than the individual background variables. Students did not regard access to e‐learning on campus as a benefit. Male students, students with previous knowledge of computers and students with positive attitudes to new technologies were all less positive to e‐leaming on campus than other students.     

Examining the Effect of Enactment of a Geospatial Curriculum on Students’ Geospatial Thinking and Reasoning

A potential method for teaching geospatial thinking and reasoning (GTR) is through geospatially enabled learning technologies. We developed an energy resources geospatial curriculum that included learning activities with geographic information systems and virtual globes. This study investigated how 13 urban middle school teachers implemented and varied the enactment of the curriculum with their students and investigated which teacher- and student-level factors accounted for students’ GTR posttest achievement. Data included biweekly implementation surveys from teachers and energy resources content and GTR pre- and posttest achievement measures from 1,049 students. Students significantly increased both their energy resources content knowledge and their GTR skills related to energy resources at the end of the curriculum enactment. Both multiple regression and hierarchical linear modeling found that students’ initial GTR abilities and gain in energy content knowledge were significantly explanatory variables for their geospatial achievement at the end of curriculum enactment, p < .001. Teacher enactment factors, including adherence to implementing the critical components of the curriculum or the number of years the teachers had taught the curriculum, did not have significant effects on students’ geospatial posttest achievement. The findings from this study provide support that learning with geospatially enabled learning technologies can support GTR with urban middle-level learners.     

Assisting Performance in Teaching and Learning

Although Vygotskian principles involving the Zone of Proximal Development (ZPD) are hailed as tenets undergirding teaching and learning within a constructivist setting, these principals have not been implemented widely within school classrooms. Tharp and Gallimore, building on the notion that learning can be maximized when a teacher has a heightened awareness of a student's ZPD and stimulates new learning based upon this understanding, argue that true teaching is a matter of “assisting performance”. This study examines the efforts of one university instructor to assist the performance of her graduate students as they learned to teach, scaffold and support struggling readers. The findings suggest that the university instructor successfully assisted her students by providing supportive feedback, extending their learning and providing appropriate resources through ongoing Email correspondence and face‐to‐face meetings and tutoring sessions. Success was attributed to the instructor's extensive knowledge of supporting struggling readers, awareness of her students' ZPD's in relation to the context of their learning and her efforts to consistently provide appropriate and specific feedback through iterative dialogue.
