Objective To develop an online discrete choice experiment (DCE) to elicit preferences for the format and content of tobacco treatment and determine the feasibility of the survey in face-to-face online interviews among college students. format content Participants A convenience sample of 28 college students. Methods A pilot online DCE survey with…

Background: Developing self-directed learning (SDL) skills in engineering students is critical to support life-long learning. This research was conducted at Iron Range Engineering (IRE), an innovative, problem-based learning (PBL) engineering program, which has suffused the concept of metacognition throughout its curriculum. Purpose/Hypotheses:…

As learning center professionals, we have much to gain by conducting assessment to understand how our services help college students develop their academic strategies. The type of data we collect makes a difference in the interpretations we can draw, however. An initial step in becoming a scholarly practitioner is to consider the strengths and…

Models of physical systems are used to explain and predict experimental results and observations. The Modeling Framework for Experimental Physics describes the process by which physicists revise their models to account for the newly acquired observations, or change their apparatus to better represent their models when they encounter discrepancies…

The purpose of this study was to gain insight into 30, first year calculus students' understanding of the relationship between the concept of vertex of a quadratic function and the concept of the derivative. APOS (action-process-object-schema) theory was applied as a guiding framework of analysis on student written work, think-aloud and follow up…

Zero-order systems provide an interesting opportunity for students to think about the underlying mechanism behind the physical phenomena being modeled. The work reported here is part of a larger study that seeks to characterize how students integrate chemistry and mathematics in the context of chemical kinetics. Thirty-six general chemistry…

Previous studies have examined the online research behaviors of graduate students in terms of how they seek and retrieve research-related information on the Web across diverse disciplines. However, few have focused on graduate students' searching activities, and particularly for their research tasks. Drawing on Kuiper, Volman, and Terwel's (2008)…

Data and graphic analysis and interpretation are important parts of science process skills and science curriculum. So it refers to visual display of data using relevant graphical representations. One of the tools used in science courses is graphics for explain the relationship among each of the concepts and therefore it is important to know data…

Research comparing the use of retrospective interviews (RIs) and think-aloud protocols (TAPs) as two data sources of writers' composing processes is almost nonexistent. Trying to address this research gap, the present study examined the data obtained from the task-specific RIs and TAPs about the composing processes of 30 second language (L2)…

Reasoning skills have been clearly related to achievement in introductory undergraduate biology, a course with a high failure rate that may contribute to dropout from undergraduate STEM majors. Existing measures are focused on the experimental method, such as generating hypotheses, choosing a research method, how to control variables other than…

The purpose of this study was to determine how students, teachers, and outside observers perceive teaching effectiveness within a university-level string ensemble rehearsal setting. Students, teachers, and observers reflected on six rehearsal segments that used primarily nonverbal, co-verbal, or verbal instruction as outlined by Bob Culver in the…

This study reports the findings of a qualitative case study that examined how elements of design and organization were conceptualized and enacted in two graduate level online courses, and, how these conceptualizations and enactments evolved. Data was collected through interviews and "think-alouds" with the course instructors and through…

The purpose of this article is to describe the process of a proof construction. It is more specific on the failure of the process. Piaget's frameworks, assimilation and accommodation, were used to analyze it. Method of this research was qualitative method. Data were collected by asking five students working on problems of proof using think aloud…

Instruction promoting reasoning and proof should be a part of K-12 mathematics teaching. Preservice teachers (PSTs) need mathematics content instruction that helps them construct valid justifications for mathematical notions and develop positive perceptions of proof. This case study describes instruction with proof-related tasks and manipulatives…

Second language (L2) reading research suggests that successful reading comprehension usually involves a repertoire of strategies. Although Chinese is considered to be a challenging language for foreign language readers, thus far, few studies have investigated how strategies are orchestrated by readers of Chinese as a foreign language (CFL) to…
