PURPOSE For depressed older primary care patients, this study aimed to examine (a) characteristics associated with depression treatment preferences; (b) predictors of receiving preferred treatment; and (c) whether receiving preferred treatment predicted satisfaction and depression outcomes. DESIGN AND METHODS Data are from 1,602 depressed older primary care patients who participated in a mult...

To investigate the effect of massed and distributed collaborative and non-collaborative presentation on L2 learners’ comprehension and production of lexical collocations, 105 participants at Takestan Islamic Azad University in 4 groups were assigned to four different treatment conditions (collaborative-massed; collaborative-distributed; noncollaborative-massed; and noncollaborative-distributed ...

Two critical issues of the typical computer-supported collaborative learning (CSCL) systems are inappropriate selection of student groups and inaccurate assessment of individual contributions of the group members. Inappropriate selection of student groups often leads to ineffective and inefficient collaboration, while inaccurate assessment of individual contributions of the group members (1) hi...

high blood pressure has become increasingly commonbetween people and also it takes a major risk factor for many diseases. the present study is done toperformthe collaborative care model in patients with high blood pressure. hypertension is defined as: systolic blood pressure (sbp) ≥140 mmhg or diastolic blood pressure (dbp) ≥90 mmhg .a collaborative care model is a native educating method based...

Introduction: Wikis are multiuser platforms that have been used with positive results for learning in higher education. As knowledge artefacts they include both semiotic and material aspects that could potentially be realized through collaborative learning and the assessment of interprofessional and problem based learning using portfolios. Purpose: The aim of the present study is to investigate...

Automatic assessment of group processes in collaborative groups is one of the holy grails of the computer supported collaborative learning community. The conversation in collaborative work provides an important window into the inner workings of a group. In this paper we present work towards detecting where students are displaying “reasoning” in conversational speech and how others are building ...

Collaborative problem solving (ColPS) proficiency was developed as a new assessment for the Programme for International Student Assessment (PISA) in the 2015 international evaluation of student skills and knowledge. The assessment framework defined by the PISA ColPS 2015 expert group crossed three major collaboration processes with four problem solving processes that were adopted from the PISA ...

Recommendation and collaborative filtering systems are important in modern information and e-commerce applications. As these systems are becoming increasingly popular in the industry, their outputs could affect business decision making, introducing incentives for an adversarial party to compromise the availability or integrity of such systems. We introduce a data poisoning attack on collaborati...

In this paper we propose an approach to organizing Adaptive Problem-Based Learning (PBL) leading to the development of Higher-Order Thinking (HOT) skills and collaborative skills in students. Adaptability of PBL is expressed by changes in fixed instructor assessments caused by the dynamics of developing HOT skills needed for problem solving, flexible choice of control tests and problems for stu...
