The effect of case based learning on tenth grade students' understanding of human reproductive systemand their perceived motivation

Saral, Sevim
The effect of case based learning on 10th grade students’ academic achievement in the unit of human reproductive system and their perceived motivation (Intrinsic Goal Orientation, Extrinsic Goal Orientation and Task Value) was investigated in this study. The study was conducted during 2007-2008 spring semester in a private high school in Ankara, Turkey. A total of 80 (48 males and 32 females) tenth grade students from four biology classes of two teachers were involved in the study. One class of each individual teacher was assigned as control group and the other class of the same teacher was assigned as experimental group to sustain randomization. Two of the classes assigned as experimental group were instructed with case based learning, while two classes of the control group were received traditionally designed biology instruction. In the experimental group, two cases that are divided into several parts were assigned in an interrupted manner. Students learned the human reproductive system via cases in experimental group without any additional method. The cases include incomplete data and students were needed to search for and discuss to answer the questions posed in the cases and by themselves and to complete the data. When the students completed a part of the case, next part was distributed. While dealing with the dilemma presented in cases, students did independent study as well as group work. In the control group, instruction was based on teacher explanations and web based notes prepared by the biology department of the high school. Human Reproductive System Achievement Test, Motivated Strategies for Learning Questionnaire were administered as pre-test and post-test to the students in both groups to measure the students’ academic achievement in the unit of human reproductive system; and their perceived motivation; specifically, task value, intrinsic goal orientation, and extrinsic goal orientation. Multivariate Analysis of Variance (MANOVA) was used to investigate the effect of case based learning on the students’ academic achievement in the unit of human reproductive system and their perceived motivation. Results revealed that case based learning improved students’ academic achievement and task value.

Karacan, Nurten; Güneri, Oya; Department of Educational Sciences (2009)
This study aims to design and investigate the effect of “Self-Esteem Enrichment Bibliocounseling Program” on the self-esteem level of sixth grade students. Twenty four subjects (13 female, 11 male) out of 166 total sixth grade students from a university affiliated private middle school in Ankara, were randomly selected based on Coopersmith Self-Esteem Inventory (CSEI) total scores and assigned to treatment and no-treatment control group conditions. An experimental design with one selfesteem treatment group ...

Apaçık, Mükerrem; Bulut, Safure; Department of Secondary Science and Mathematics Education (2009)
The purpose of the study was to determine the effects of problem-based learning (PBL) on 9th grade students’ geometry achievement. The study was conducted in a rural town of Ankara with 44 ninth-grade high school students. The randomized pretest-posttest control group design was used. The experimental group was instructed with hybrid PBL and the control group was instructed with traditional teaching methods. The treatment was given for 4 hours every week for a total of six weeks. Geometry Achievement Test (...
The importance of teacher-student interpersonal relationships for Turkish students' attitudes towards science
Telli, Sibel; den Brok, Perry; Çakıroğlu, Jale (Informa UK Limited, 2010-01-01)
The purpose of this study was to examine associations between Turkish high school students' perceptions of their science teachers' interpersonal behaviour and their attitudes towards science. Students' perceptions of the teacher-student interpersonal relationship were mapped with the Questionnaire on Teacher Interaction (QTI), which uses two relational dimensions: influence and proximity. Data on Students' subject-related attitudes were collected with the Test of Science Related Attitudes (TOSRA). A total o...
The Relationship Among Mathematics Teaching Efficacy, Math Anxiety, and Mathematical Self-Concept: The Case of Turkish Pre-Service Elementary Teachers
Işıksal Bostan, Mine (Philippines Journals Online (PhilJOL), 2010-11-01)
The purpose of this study was to investigate the relationship among pre-service teachers' mathematics teaching efficacy belief, math anxiety, and mathematical self-concept scores. The analysis was based on 276 elementary pre-service teachers enrolled in teacher education programs in Turkey. The Mathematics Teaching Efficacy Belief Instrument, the Abbreviated Mathematics Anxiety Scale, and the Experience with Mathematics Questionnaire were used as the measuring instruments. Structural equation modeling was u...
The effect of conceptual change based instruction on students’ understanding of rate of reaction concepts
Kaya, Ebru; Geban, Ömer; Department of Secondary Science and Mathematics Education (2011)
The purpose of this study was to investigate the effects of conceptual change based instruction accompanied by demonstrations (CCBIAD) and gender on 11th grade students’ understanding and achievement in rate of reaction concepts, and their attitudes toward chemistry as a school subject compared to traditionally designed chemistry instruction (TDCI). Sixty nine 11th grade students from two classes in a public high school in Ankara participated in this study in the Fall Semester of 2008-2009. These classes we...
