Differential effects of problem-solving demands on individual and collaborative learning outcomes

The effectiveness and efficiency of individual versus collaborative learning was investigated as a function of instructional format among 140 high school students in the domain of biology. The instructional format either emphasized worked examples, which needed to be studied or the equivalent problems, which needed to be solved. Because problem solving imposes a higher cognitive load for novices than does studying worked examples it was hypothesized that learning by solving problems would lead to better learning outcomes (effectiveness) and be more efficient for collaborative learners, whereas learning by studying worked examples would lead to better learning outcomes and be more efficient for individual learners. The results supported these crossover interaction hypothesis. Consequences of the findings for the design of individual and collaborative learning environments are discussed.     

Timing of Information Presentation in Learning Statistics

This study in the domain of statistics comparesfour information presentation formats in a 2 × 2factorial design: timing of supportiveinformation (before or during taskpractice) × timing of procedural information(before or during task practice).Seventy-two psychology and education students(7 male and 65 female; mean age 18.5 years,SD = 2.85) participated. Theeffectiveness of the learning material wasmeasured by test performance. The instructionalefficiency was measured by a combination ofmental effort during practice and testperformance (i.e., a high test performancecombined with a low mental effort duringpractice denotes a high instructionalefficiency). ANOVA showed a main effect fortiming of supportive information: presentationduring practice led to more efficient learning than presentationbefore practice. Moreover, an interactioneffect was found. Simultaneous presentation ofprocedural information before andsupportive information during practiceled to the most efficient learning.     

Practical work at the Open University of the Netherlands

Achieving practical objectives in an open distance educational system is a real challenge. Its philosophy requires self-instructional materials that students can study at their own time, place, and pace. Practical work, in particular laboratory work, can test the limits of this philosophy. A new way of thinking about practical work and modern electronic media make it possible to develop a natural sciences degree program with a minimum amount of laboratory sessions and, hopefully, to pursue practical aims which are useful in the student's later profession. The way the Open University of the Netherlands has been developing a practical program according to these starting points is discussed in the first part of this paper. Examples of alternatives for traditional practical work are described in more detail in the second part. Advantages and disadvantages with regards to traditional practical work are discussed.     

Fostering self-regulation in training complex cognitive tasks

In complex cognitive domains such as air traffic control, professionals must be able to adapt to and act upon continuing changes in a highly advanced technological work environment. To function optimally in such an environment, the controllers must be able to regulate their learning. Although these regulation skills should be part of their training, this is not usually the case. This study evaluates a training program that integrates air traffic control skills with regulation skills. The participants were 29 air traffic control students who followed either the original training program (n = 12) or a new program (n = 17) in which the development of regulation skills was embedded in the training of domain specific skills. Compared to students in the original program, the students in the new program showed increased self-efficacy in the use of self-regulated learning skills with improved performance in domain specific competences. The implications of these findings are discussed with regard to the daily training practice of complex cognitive skills.     

A computer-supported method to reveal and assess Personal Professional Theories in vocational education

This article introduces a dedicated, computer-supported method to construct and formatively assess open, annotated concept maps of Personal Professional Theories (PPTs). These theories are internalised, personal bodies of formal and practical knowledge, values, norms and convictions that professionals use as a reference to interpret and acquire knowledge, and to direct their behaviour, and which vocational students are expected to develop. Monitoring the development of PPTs and assessing their quality are difficult as they are, essentially, mental schemes. Traditional methods, such as semi-structured interviews and concept mapping, are either too labour-intensive to be used in an educational setting or are not able to reveal their full quality. The study presents a new method which is valid, reliable and easy to use in education and which reveals the quality in a way that is comparable to or better than interviews.     

Teachers’ opinions on quality criteria for Competency Assessment Programs

Quality control policies towards Dutch vocational schools have changed dramatically because the government questioned examination quality. Schools must now demonstrate assessment quality to a new Examination Quality Center. Since teachers often design assessments, they must be involved in quality issues. This study therefore explores teachers’ opinions on assessment quality evaluation criteria. Pre-vocational and vocational teachers (N=211$N=211$) responded to a questionnaire. Contrary to expectations, results show that teachers deem classical and competency-based quality criteria equally important. Vocational teachers gave higher importance scores than pre-vocational teachers, possibly due to the pressure they experience to improve the quality of their assessments.     

Audiotape feedback for essays in distance education

Students who were required to write three short essays for a university level course on photochemistry at the Open university of the Netherlands received either audio-cassette or written feedback on their essays. The students receiving the audio feedback described their experience as personal, enjoyable, complete and clear. Those receiving written feedback described their experience as adequate. The amount of time spent by instructors supplying the feedback differed minimally (X_audio=53 minutes per student; X_written=49 minutes) with the major difference lying in the amount of time spent in preparation. This difference, possibly attributable to novelty with audio as a mode for feedback, was not significant. The amount communicated to the students with audio feedback (per instructor) was significantly greater than the amount communicated with written feedback. There was no difference in the final grades for the two groups of students.Paul A. Kirschner received his Masters in Educational Psychology from the State University of Amsterdam.

Social Aspects of CSCL Environments: A Research Framework

Although there are research findings supporting the positive effects of computer-supported collaborative learning (CSCL), problems have been reported regarding the learning process itself, group formation, and group dynamics. These problems can be traced back to impeded social interaction between group members. Social interaction is necessary (a) for group members to learn from each other in a CSCL environment and (b) for socioemotional processes to help create a social space where trust, sense of community, and strong interpersonal relationships exist. This article introduces a theoretical framework consisting of three core elements: sociability, social space, and social presence, along with their relationships with group members’ mental models, social affordances and learning outcomes. It postulates that the three core elements influence the social interaction needed for both learning and the emergence of a social space. This framework serves as a basis for a research agenda for systematic social CSCL research.
