This study developed the software named as أPhysical Worldؤ which is a virtual laboratory program focusing on Newtonian Physics, which supports two modes called the أstudying by observationؤ and أstudying by programmingؤ. In أstudying by observationؤ mode, the motion is calculated due to equations known by the computer. And in أstudying by programmingؤ mode, students write equations of motion and the computer calculates motion due to those equations. A total of six high school second grade students studied force and motion concepts, using Physical World with assistance of one instructor, six hours each. Two of the students studied with أstudying by observationؤ, two of the students studied with أstudying by programmingؤ, and two of the students studied with use of both of the modes. All students received a test with 10 items chosen from FCI as a pretest and received the same test as a posttest. Students̕ test results were examined to find effects of Physical World̕s two modes and use of both of the modes over misconceptions about physics. Their actions and responds were examined to find Physical World̕s effects on scientific thinking for each of the three groups. Four specialists from related fields examined the software and filled evaluation forms and stated feedbacks. From the responds of students during the studies, evidence of positive effect of using the أstudying by programmingؤ mode on scientific thinking was found. And evidence of positive effect of using both modes on misconceptions was found.

Development of a three-tier test to assess ninth grade students' misconceptions about simple electric circuits
Peşman, Haki; Eryılmaz, Ali; Department of Secondary Science and Mathematics Education (2005)
The main purpose of this study was to develop a three-tier test for assessing ninth-grade students̕ misconceptions about simple electric circuits. The first tier of an item on the test presents an ordinary multiple choice question, the second tier presents a set of reasons for the response given to the first tier, and the third tier questions if examinees are confident for their responses to the first two tiers. The study was carried in Polatlı, the biggest outlying district of capital Ankara. In the light ...
Effectiveness of conceptual change instruction on overcoming students' misconceptions of electric field, electric potential and electric potential energy at tenth grade level
Vatansever, Orhan; Sancar, Mehmet Tevfik; Department of Secondary Science and Mathematics Education (2006)
The purpose of this study was to investigate the effectiveness of the conceptual change text based instruction over traditionally designed physics instruction to overcome tenth grade students’ misconceptions on electric field, electric potential and electric potential energy concepts. To provide conceptual change, conceptual change texts (CCT) were developed by the researcher. An Electric Potential and Electric Potential Energy Concept Test (EPEPECT) which consists of 10-items was developed and used to exam...
Comparison of linear and adaptive versions of the Turkish pupil monitoring system (PMS) mathematics assessment
Gökçe, Semirhan; Berberoğlu, Halil Giray; Department of Secondary Science and Mathematics Education (2012)
Until the developments in computer technology, linear test administrations within classical test theory framework is mostly used in testing practices. These tests contain a set of predefined items in a large range of difficulty values for collecting information from students at various ability levels. However, placing very easy and very difficult items in the same test not only cause wasting time and effort but also introduces possible extraneous variables into the measurement process such as possibility of...
SIMULATION OF ELECTRON-DIFFRACTION PATTERNS OF ALLOYS WITH ORIENTED PRECIPITATES
AKBAY, T; Aydınol, Mehmet Kadri; BOR, AS (1994-06-01)
A computer program has been developed to simulate the complicated electron diffraction patterns of alloys consisting of an underlying matrix phase in which are embedded various crystallographically oriented precipitates. These precipitates consist of different variants each with a specific orientation relationship to the underlying matrix. The program is designed to calculate the number of possible variants and the specific orientation of each variant using a general orientation relationship input by the us...
A structural equation modeling study : factors related to mathematics and geometry achievement across grade levels
Gökçe, Semirhan; Berbeoğlu, Halil Giray; Department of Secondary Science and Mathematics Education (2005)
The factors related to mathematics and geometry achievement were modeled in this study. It was based on the data obtained from the Student Assessment Program carried out by Ministry of National Education. Mathematics achievement tests and student questionnaires of each grade were analyzed by using principal component analysis to obtain different dimensions that are expected to be related with student achievement. Before the principal component analysis, a content based evaluation of the content of the mathe...
