Exploring the interactive patterns of concept map-based online discussion: a sequential analysis of users’ operations,cognitive processing,and knowledge construction

Concept maps can be used as a cognitive tool to assist learners' knowledge construction. However, in a concept map-based online discussion environment, studies that take into consideration learners' manipulative actions of composing concept maps, cognitive process among learners' discussion, and social knowledge construction at the same time are still lacking. Therefore, this study employed lag sequential analysis to empirically explore learners' behavioral patterns in a concept map-based online discussion environment. We explored learners' operations in the concept map tool, and their discussion behavioral patterns of cognitive processing phases and social knowledge construction. The results showed that it was easier for learners to define a node than to define a relationship when they used the concept map. Additionally, the concept map can enhance higher level cognitive processing phases and lead learners to return to the main discussions from off-topic discussions significantly.     

A context-specific detrimental effect of UCS preexposure on place conditioning with morphine

The effect of morphine preexposure on place conditioning with morphine was investigated. In the first experiment, five injections of 10 mg/kg morphine were administered to rats prior to place conditioning or taste-aversion training with morphine. Although this number of preexposures retarded taste-aversion learning, there was no effect on place conditioning. In subsequent experiments we investigated the role of context blocking in UCS preexposure in place conditioning. In one experiment, preexposure to five morphine injections prior to place conditioning resulted in a reduced place preference, compared with preexposure and place conditioning in different contexts. However, the overall detrimental effect of morphine preexposure was questionable, because the rats that were preexposed were only marginally different from those that were not preexposed. In a final experiment we examined the effect of a context change from preexposure to place conditioning with 15 preexposures and demonstrated a detrimental effect of preexposure on place conditioning that was context specific. These results support a role of classical conditioning in place-preference conditioning with morphine.     

Understanding the Link Between Noncognitive Attributes and College Retention

The attention to students’ noncognitive attributes has recently flourished within academic research and public discourse. This paper adds to the literature by examining the interrelationships among several key noncognitive attributes as well as exploring direct and indirect relationships between noncognitive attributes and second-year retention. Within a multi-institutional sample of 10,622 students, academic self-efficacy, academic grit, self-discipline, and time management all load onto a single noncognitive factor with strong inter-item correlations and internal reliability. Moreover, structural equation modeling analyses indicate a sizable and positive indirect effect of noncognitive attributes on college retention, which is mediated by social adjustment, institutional commitment, and college grade point average.

     

Belief, Knowledge, and Science Education

Epistemological questions about the nature of knowledge and belief underlie many of the controversial issues fundamental to research and practice in science teaching and learning. In an effort to bring some clarity to questions of knowledge and belief embedded within science education research and teaching, we first describe the distinctions drawn between knowledge and belief in both philosophy and educational psychology, each of which have shaped the various definitions employed within science education. This discussion is followed by an examination of the distinctions drawn between knowledge and belief employed by three groups of science educators: the traditional distinctions of the foundationalists that are co-opted by researchers focusing on teacher thinking/cognition, the nonfoundational epistemology of the fallibilists and the evolution educators working from this framework, and the radical constructivists who react to and attempt to move past the limitations of these other positions. In this analysis, we explicate the different ways in which knowledge and belief are understood and operationalized in a broad spectrum of research, we describe the theoretical and philosophical assumptions underlying these approaches, and we explore the important areas of contention (both theoretical and empirical) surrounding each of these distinctions.     

Investigation of multiple human factors in personalized learning

In the past decade, a number of personalized learning systems have been developed and they mainly focus on learners' prior knowledge. On the other hand, previous research suggested that gender differences and cognitive styles have great effects on student learning. To this end, this study examines how human factors, especially gender differences and cognitive styles, affect learners' reactions to a personalized and non-personalized learning systems based on learners' prior knowledge. Forty-four university students participated in this study. The results show that females and Serialists show positive reactions to the personalized learning system, while males and Holists demonstrate similar reactions to the personalized learning system and the non-personalized learning system. The implications of these results for the design of personalized learning systems are discussed.     

Multisensory programs in the public schools: A brighter future for LD children

A longitudinal study followed the progress of a group of elementary SLD students as they were instructed using the Alphabetic Phonics (AP) curriculum. After a three year period, the AP curriculum produced positive results in reading comprehension for most SLD students, particularly those who began the program in first and second grade. Students in resource and self-contained settings made significant gains in reading comprehension, although the two types of students exhibited different patterns of progress. Students of different ability levels responded differently to the AP curriculum. Average and above average students made significant progress in reading comprehension, but below average students did not advance substantially in relation to their ability level. At the end of three years, classroom teachers had a significantly more positive view of students’ word attack, oral reading, and silent reading comprehension skills.     

Using a Multilevel Assessment Scheme in Reforming Science Methods Courses

The development of new courses is strengthened by assessment and a response to the assessment. Two new science methods courses for elementary and secondary preservice teachers were developed, fostered by the Great Salt Lake Project. The preservice teachers designed and performed research projects that they then converted into inquiry-based teaching units. The professors applied a 3-layer assessment scheme to evaluate the courses and the preservice teachers based on changes in student attitudes, student-generated curricula, and internal course evaluations. Each type of assessment effectively informed the reform process, and strengths and weaknesses of the courses were revealed. Strengths of the courses included students learning to see science as a process and comprehending inquiry as a pedagogical approach. Weaknesses observed included a lack of understanding in three areas: the role of assessment, the need to address cultural issues, and the significance of scientific literacy.     

Professional currency among midcareer college faculty: Family and work factors

This study examined work and family factors that differentiate midcareer faculty members who were current from less current faculty with regard to the disciplinary knowledge base. The sample included 97 faculty (69 males, 28 females; 72 English, 25 Engineering) and their spouses. Cluster analyses of the work and family variables identified faculty subgroups within discipline. ANCOVAs showed a significant relationship between the clustered work-family profiles and levels of currency.Family differences: Current faculty and spouses reported spending more time on family-related responsibilities and experiencing greater stress from combined work-family responsibilities. Current Engineering faculty reported less flexibility in reallocating family responsibilities.Work differences: Faculty reported a greater commitment to their careers and to professional development: They reported higher scores on the Inner Work Standards scale; current English faculty read more professional journals and spent more time on research; current Engineering faculty spent more time on research and had more publications.     

The Juvenile Victimization Questionnaire: reliability, validity, and national norms

OBJECTIVE: To assess the utility and performance of the 34-item Juvenile Victimization Questionnaire (JVQ) in eliciting the recent victimization experiences of a national sample of children ages 2-17. METHOD: The JVQ was administered in a national random digit dial telephone survey about the experiences of 2,030 children. The experiences of children 10-17 years old were assessed through youth self-report on the JVQ, and the experiences of children 2-9 assessed through JVQ caregiver proxy report. RESULTS: Large numbers of recent victimizations were disclosed using the JVQ (71% of the sample reporting at least one victimization in the last year, with an average of 2.63 victimizations per child). There were few indicators of respondent confusion and little resistance to even the most sensitive questions. In a test of construct validity, endorsements of JVQ items correlated well with measures of traumatic symptoms. The instrument showed adequate test-retest reliability in a 3 to 4 week re-administration. Large numbers of victimizations were reported across the spectrum of ages, and there were no major discontinuities between the self-reports and proxy reports, suggesting that caregivers provided generally adequate and comparable information to child self-reports about the experiences of children under the age of 10. CONCLUSION: The JVQ has potential for use in future epidemiological research as well as clinical evaluation concerning the victimization of children.     

Exploring the effectiveness of engagement in a broad range of disciplinary practices on learning of Turkish high-school chemistry students

This study examines the influence of laboratory instruction that engages students in a wide range of the practices of science on Turkish high-school students’ chemistry learning. In this mixed methods study, student learning in two different laboratory settings was compared, one that featured an instruction that engaged students in a wide range of disciplinary practices (through Argument-driven Inquiry – ADI) and similar laboratories in which a more traditional Structured Inquiry (SI) approach was employed. The data sources included a Chemistry Concept test, an Argumentative Writing Assessment, and Semi-structured interviews. After seven weeks of chemistry instruction, students experiencing ADI instruction scored higher on the Chemistry Concept test and the Argumentative Writing Assessment than students experiencing SI instruction. Furthermore, girls who experienced ADI instruction scored higher on the assessments than their majority peers in the same class. The results suggest that Turkish students can substantially improve their chemistry proficiency if they have an opportunity to engage in instruction featuring a broad array of the practices of science.
