Abstract

This study aimed to generate learning trajectories in learning number patterns by using lego in grade IX SMP. This study was conducted in SMP N 1 Tanjung Raja. The method of this study was design research consisted of three phases, i.e. preliminary, design experiment (pilot experiment and teaching experiment) and retrospective analysis. In this study, a series of instruction was designed and developed based on conjecture of learning processes and PMRI approach. In this paper discussed was teaching experiment phase. Results of this research was learning trajectory that includes a series of learning process that were activity constructs patterns by using Lego generate sequence to determine rules and the next number of sequence, activity outlines pattern to determine the n-th pattern of sequence, until activity number patterns to determine the amount of n tribe/number. Based on the activities undertaken in this study could help students to understand number patterns.

Abstract

Photic driving (PD) is a normal electroencephalography phenomenon in the parietooccipital region  during intermittent photic stimulation (IPS). The PD response is an indicator that is sensitive to age, brain maturity, certain abnormalities, changes in brain signal and brain complexity. Currently, there is not much  data about the PD response based on individual characteristics. Methods: It is a cross-sectional study with secondary data from EEG and medical records,  from January to December 2017. Result: Of 536 records, only 444 EEG records fulfilled the research criteria. PD response was more common in women (61.4%) and age group between 20-60 years (78.6%). Normal EEG result was 71.4%. PD responses were most commonly diagnosed with epilepsy etiology (33.8%). Only 28.6% of PD responses were found in abnormal EEG results. Conclusion: Distribution showed that the response of PD decreased in older age. The PD response is more common in patients with normal EEG results.  The more abnormal results of EEG, PD response rarely arise.
