Facilitating Computer-Supported Collaborative Learning with Question-Asking Scripting Activity and its Effects on Students’ Conceptual Understanding and Critical Thinking in Science

Computer-supported collaborative learning (CSCL) provides an environment that enhances social interaction and shared knowledge construction among students. However, limited research has examined CSCL reinforced by question-asking scripting activity. This research investigated the effects of CSCL with question-asking scripting activity on the development of conceptual understanding and critical thinking in science. Moreover, the research design was a three-group pre-test-post-test quasi-experimental study in which the research sample were 106 Grade 7 students. The only difference between the control and the experimental groups was the exposure to CSCL. The experimental groups were exposed to CSCL approaches: one without scripting while one was exposed with question-asking scripting activity. Results revealed that CSCL approaches significantly affected the development of students’ conceptual understanding and critical thinking. Specifically, CSCL with scripting stimulated more intellectual discussion which allowed learners to deepen lesson comprehension and improve their critical thinking skills. Insights on the innovations through technology integration, collaborative inquiry learning, and question-asking activity to enhance science education were also discussed. The findings of this study have important implications for future practice

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
