New societal demands call for schools to train students' collaboration skills. However, research thus far has focused mainly on promoting collaboration to facilitate knowledge acquisition and has rarely provided insight into how to train students' collaboration skills. This study demonstrates the positive effects on the quality of students' collaboration and their knowledge acquisition of an instructional approach that consists of conventional instruction and an online tool that fosters students' joint reflection on their collaborative behavior by employing self-and peer assessment and goal setting. Both the instruction and the collaboration reflection tool were designed to promote students' awareness of effective collaboration characteristics (the RIDE rules) and their own collaborative behavior. First-year technical vocational students (N = 198, M age = 17.7 years) worked in heterogeneous triads in a computer-supported collaborative learning environment (CSCL) on topics concerning electricity. They received either 1) conventional instruction about collaboration and the online collaboration reflection tool, 2) collaboration instruction only, or 3) no collaboration instruction and no tool. Analysis of chat data (n = 92) and knowledge tests (n = 87) showed that students from the instruction with tool condition outperformed the other students as far as their collaborative behavior and their domain knowledge gains.

Abstract. Nowadays, the knowledge economy is growing rapidly. To sustain future growth, more well educated people in STEM (science, technology, engineering and mathematics) are needed. In the Go-Lab project we aim to motivate and orient students from an early age on to study STEM fields in their future educational path by applying inquiry learning using online labs. This paper presents an inquiry learning portal where teachers can discover, use and enhance online labs appropriate for their courses and students can acquire scientific methodology skills while doing experiments using the labs. The Go-Lab portal architecture is presented, which contains a repository of online labs, inquiry learning spaces and complementary services. The paper discusses a first version of the portal and our future plans.

Despite a growing effort to implement computational thinking (CT) skills in primary schools, little research is reported about what CT skills to teach at what age. Therefore, the research questions that guide this study read: (1) How is age related to students' success in computational thinking tasks? (2) How are computational thinking tasks perceived by students? (3) How do students' experience learning with respect to computational thinking? 200 primary school students between the age of 6 and 12 participated in this study. These students got introduced to two CT subjects: abstraction and decomposition. We found that age seems to be related with these concepts, with an interaction effect for gender in the abstraction task. No differences found between young and older students in the constructs perceived difficulty, cognitive load, and flow indicate that young primary school students can engage in learning these CT skills.

Science Created by You (SCY) is a project on learning in science and technology domains. SCY uses a pedagogical approach that centres around products, called 'emerging learning objects- (ELOs) that are created by students. Students work individually and collaboratively in SCY-Lab (the general SCY learning environment) on 'missions' that are guided by socio-scientific questions (for example 'How can we design a CO2-friendly house?'). Fulfilling SCY missions requires a combination of knowledge from different content areas (eg, physics, mathematics, biology, as well as social sciences). While on a SCY mission, students perform several types of learning activities that can be characterised as productive processes (experiment, game, share, explain, design, etc), they encounter multiple resources, collaborate with varying coalitions of peers and use changing constellations of tools and scaffolds. The configuration of SCY-Lab is adaptive to the actual learning situation and ma y provide advice to students on appropriate learning activities, resources, tools and scaffolds, or peer students who can support the learning process. The SCY project aims at students between 12 and 18 years old. In the course of the project, a total of four SCY missions will be developed, of which one is currently available

Creating shared representations can foster knowledge acquisition by elementary school students by promoting active integration and translation of new information. In this study, we investigate to what extent awareness support and scripting facilitate knowledge construction and discourse quality of elementary school students (n=94) in a computersupported collaborative drawing scenario. Students in the awareness condition received feedback prompts based on the characteristics of their drawing. The script foresaw a sequence of creating, comparing, discussing, and merging individual drawings to arrive at a shared representation of the subject matter, which was photosynthesis. Both forms of support, (awareness and scripting) facilitated the learning processes and outcomes. Discourse analysis revealed that awareness and scripting increased (the share of) integrative and conflict-oriented consensus-building activities as well as (the share of) off-task and coordination-related activities in comparison to the control group. Awareness and scripting facilitated deeper understanding of the processes and relations of domain concepts. The scripted students acquired significantly more conceptual knowledge than the unscripted students.
