The purpose of this study is to develop a survey of technological pedagogical and content knowledge (TPACK). The survey consists of seven subscales forming the TPACK model: 1) technology knowledge (TK), 2) pedagogy knowledge (PK), 3) content knowledge (CK), 4) technological pedagogical knowledge (TPK), 5) technological content knowledge (TCK), 6) pedagogical content knowledge (PCK), and 7) TPAC...

Abstract This study identifies proficiency levels in pre‐service physics teachers' pedagogical content knowledge (PCK) and reveals how teacher education can promote transitions into higher proficiency. Teacher plays a fundamental role supporting PCK development. Proficiency are powerful source when evaluating this development because they characterize what learners likely to be able know on spe...

The study investigates how Science teachers articulate their self-confidence in teaching with technology. Technological Pedagogical Content Knowledge (TPACK) is used as the primary tool to describe practice. Using a quantitative approach, an initial survey of 408 science from 59 secondary schools state East Malaysia, descriptive and inferential statistics were conducted assess teachers’ level T...

Nitrogen fertilizer application rates in intensive agricultural systems have increased dramatically in recent years, especially in protected vegetable production systems. This excessive use of nitrogen fertilizer has resulted in soil secondary salinity, which has become a significant environmental stress for crops such as cucumber, in the protected farmlands. It is thus necessary to illuminate ...

The purpose of this study is to investigate pre-service teachers’ technological, pedagogical and content knowledge (TPACK) in Turkey. By using the “Survey of Pre-service Teachers’ Knowledge of Teaching and Technology” developed by Schmidt et al. (2009), the study sought to determine if significant differences could be found in pre-service teachers’ perceptions of TPACK when examined by gender, ...

Creatine kinase (CK) BB, a member of the CK gene family, is a predominantly cytosolic CK isoform in the brain and plays a key role in regulation of the ATP level in neural cells. CK BB levels are reduced in brain regions affected by neurodegeneration in Alzheimer's disease (AD), Pick's disease, and Lewy body dementia, and this reduction is not a result of decreased mRNA levels. This study demon...

The role of technology in education is undeniable (Niess, 2005). Teachers as moulders of human beings need to be skillful in integrating technology in education to deliver what they teach effectively. According to Malaysian Education Blueprint (2012) pre-service service teachers of Universiti Utara Malaysia are expected to master Information and Communication Technology (ICT) integration in the...

The effect of gastrointestinal surgery on serum creatine kinase activity was studied in 30 patients. The MB isoenzyme was demonstrated in sera of 30% of the patients and BB isoenzyme in 23%. MB content varied from 0.8 to 10.3% of the total creatine kinase activity, and the BB content from 0.6 to 18.4%. The CK-BB was probably of gastrointestinal origin, since gastrointestinal tract contains high...

Creatine kinase (CK) forms a small family of isoenzymes playing an important role in maintaining the concentration of ATP and ADP in muscle cells. To delineate the impact of a lack of CK activity, we studied contractile performance during a single maximal tetanic contraction and during 12 repeated tetanic contractions of intact dorsal flexors of CK knockout (CK(-/-)) mice. To investigate the ef...
