532 Brain slow potentials and psychomotor learning in skilled sharpshooting

MacDonald, Kurt D., Eva Fifkova, Michael S. Jones, and Daniel S. Barth. Focal stimulation of the thalamic reticular nucleus induces focal gamma waves in cortex. J. Neurophysiol. 79: 474–477, 1998. Electrical stimulation of the thalamic reticular nucleus (TRN; 0.5-s trains of 500-Hz 0.5-ms pulses at 5–10 μA) evokes focal oscillations of cortical electrical potentials in the gamma frequency band (∼35–55 Hz). These evoked oscillations are specific to either the somatosensory or auditory cortex and to subregions of the cortical receptotopic map, depending on what part of the TRN is stimulated. Focal stimulation of the internal capsule, however, evokes focal slow potentials, without gamma activity. Our results suggest that the TRN's role extends beyond that of general cortical arousal to include specific modality and submodality activation of the forebrain.

Cognitive Learning Outcomes

The Effect of using the Problem Based Instruction (PBI) learning model to determine the effect on learning outcomes using the Problem Based Instruction (PBI) learning process. This research is a quasi experimental research which consists of a control class and an experimental class. The control class uses the conventional learning model and the experimental class uses the Problem Based Instruction (PBI) learning model, conducted in the X MIPA 1 and X MIPA 2 in SMA Negeri 1 Rumbia. The research data were obtained from test sheets and observations at the end of each lesson. The average cognitive learning outcomes of the experimental class were 80% and the control class was 63,83%. The average psychomotor learning outcomes of the experimental class were 80,46% and the experimental class was 75%. The results showed that there was an influence of the Problem Based Instruction (PBI) learning model on the learning outcomes of students in learning biology.

Static Group

The study aims at examming 1) the difference of cognitive leraning outcomes between students who were taught by using cooperative learning model of Make a Match type and the ones taught by using The Power of Two type, 2) the difference of affective learning outcomes between students who were taught by using cooperative learning model of Make a Match type and the ones taught by using the Power of Two type 3) the difference of psychomotor learning outcomes between students who were taught by using cooperative learning model Make a Match type and the ones taught by using The Power of Two type of grade XI students at SMAN 1 Sungguminasa Makassar. The study was a quasi-experiment research which employed the static group pretest posttest design. The study used the experiment group I by implementing cooperative learning model of Make a Match type and the experiment group II by implementing cooperative learning model of The Power of Two type. The instruments of the study were the test of learning outcomes to measure the cognitive learning outcomes, observation sheet to measure affective and psychomotor learning outcomes of the students. Data were analyzed using descriptive statistic analysis and inferential statistic analysis (uji t α = 0,05 ) supported by SPSS 17.0 for windows program. that the result using The Power of Two was higher than the one using The Power of Two.Penelitian ini bertujuan untuk 1) Mengetahui perbedaan hasil belajar kognitif siswa dengan penerapan model pembelajaran kooperatif tipe Make a Match dengan kooperatif tipe The Power of Two pada siswa kelas XI SMAN. 1 Sungguminasa Makassar 2) Mengetahui perbedaan hasil belajar afektif siswa dengan penerapan model pembelajaran kooperatif tipe Make a Match dengan kooperatif tipe The Power of Two pada siswa kelas XI SMAN 1 Sungguminasa Makassar 3) Mengetahui perbedaan hasil belajar psikomotorik siswa dengan penerapan model pembelajaran kooperatif tipe Make a Match dengan The Power of Two pada siswa kelas XI SMAN 1 Sungguminasa Makassar. Jenis penelitian ini adalah quasi eksperimen dengan rancangan The static Group Pretest Posttest Design. Instrumen penelitian berupa Tes Hasil Belajar (THB) untuk mengukur hasil belajar kognitif, dan lembar observasi untuk mengukur hasil belajar afektif dan psikomotorik siswa. Data dianalisis statistik deskriptif dan inferensial (Uji t α = 0,05) dengan bantuan program SPSS 17.0 for windows. Hasil penelitian ini menunjukkan bahwa 1) Hasil belajar kognitif siswa dengan penerapan model pembelajaran The Power of Two lebih tinggi dibandingkan dengan penerapan model pembelajaran kooperatif tipe Make a Match 2) Hasil belajar afektif siswa dengan penerapan model pembelajaran tipe Make a Match lebih tinggi dibandingkan dengan penerapan model pembelajaran kooperatif tipe The Power of Two 3) Hasil belajar psikomotorik siswa dengan penerapan model pembelajaran tipe Make a Match lebih tinggi dibandingkan dengan penerapan model pembelajaran kooperatif tipe The Power of Two.

Three Stages

Background: Survey of researchers in SMP N 38 Semarang, it turns out there are still many teachers who use conventional learning methods and combinations of several methods have not involved students' cognitive, affective, and psychomotor aspects. Learning activities are still dominated by teachers. This resulted in students tend to be passive and the classroom atmosphere became teacher centered. To overcome this problem learning needs to be varied so that the learning process activates students more. Method: The study was conducted through the development method (research and development) which consisted of three stages, namely introduction, development, and evaluation. Results: Based on data analysis, cognitive learning outcomes reached 71.4% completeness with the results of the Gain Test of 0.71 (high gain category). Psychomotor learning outcomes achieved 74.60% achievement, achievement of affective learning outcomes was 73.39% while inquiry skills gained 71.52%. Conclusion: Based on the achievement of learning outcomes, it can be concluded that the devices developed are considered effective. Positive responses of students to teaching materials were 86.40%, while the positive responses of students to LKS reached 87.46%. This means that learning devices developed can be applied in learning.

Slow Activity

1. Three thresholds are demonstrated in the first segmental nerve and two (sometimes three) in the second and third segmental nerves together. 2. Slow potentials recorded from the ventral nerve cord consist of several peaks. The first peak is composed of three spikes which make their appearance at different thresholds. Transmission of at least some of the slow potentials is decremental. 3. Transmission speeds in the nerve cord and segmental nerves range from 0.4 to 0.6 m./sec. 4. Action potentials in the longitudinal muscle are recorded in response to slow potentials in the nerve cord. 5. Two slow reflexes, one involving elongation, the other longitudinal contraction, are described. The latter has the lower threshold with peripheral stimulation. 6. Slow activity in the nervous system is discussed in relation to reflex activity of the earthworm and the neurone anatomy of the nerve cord and segmental nerves.
